Brief relaxation versus music distraction in the treatment of dental anxiety: a randomized controlled clinical trial

BACKGROUND: Dental anxiety is a significant cause of poor dental health. Because patients often prefer nonpharmacological interventions, the clinical effectiveness of clearly structured approaches is of particular interest. METHODS: This prospective randomized controlled study compares a brief relaxation method (BR) with music distraction (MD) and with a control group (C). The authors randomly assigned 90 patients with dental anxiety to BR, MD or C groups. They assessed the outcomes by means of the state anxiety subscale of the State-Trait Anxiety Inventory. RESULTS: Both BR and MD reduced dental anxiety significantly. In contrast, patients in the C group did not exhibit a significant change in their anxiety level. BR was significantly superior to MD. Stratification according to the patient's general level of dental anxiety revealed that BR also was particularly effective in highly anxious subjects, whereas MD did not have a clinically relevant effect on these subjects. CONCLUSIONS: BR appears to be a safe, economically sound and effective nonpharmacological approach to the short-term reduction of dental anxiety. Additional investigations are needed to validate these findings in a larger clinical trial and to determine the long-term effects of this intervention. CLINICAL IMPLICATIONS: Relaxation techniques are a pragmatic, effective and cost-saving method of facilitating dental treatment in anxious patients.     

Pain catastrophizing in dental patients: Implications for treatment management

Background”Pain catastrophizing“ refers to an exaggerated negative mental set brought to bear during an actual or anticipated painful experience. A patient's perception of a dental care experience as catastrophic can result not only in poor satisfaction with the therapy but also in avoidance of necessary treatments, resulting in the deterioration of oral health.MethodsThe author reviewed literature regarding pain catastrophizing regarding dental treatment as well as behavioral models related to catastrophizing.ResultsPeople who catastrophize show excessive attention to pain (rumination), exaggerate the threat value of pain (magnification) and feel unable to cope with their suffering (helplessness). During dental treatments, greater pain catastrophizing is associated with increased pain, dental anxiety and negative thoughts regarding pain and dental procedures.ConclusionsIt is important that clinicians identify dental patients who catastrophize so as to plan and provide the best treatment for their needs.Practical ImplicationsTo manage the care of patients who catastrophize, the clinician can actively probe patients' pain experience, help them reappraise threat, manipulate their attention to pain and improve dentist-patient communication.     

Assessment of treatment provided by dental health aide therapists in Alaska: a pilot study

BackgroundDental health aide therapists (DHATs) in Alaska are authorized under federal law to provide certain dental services, including irreversible dental procedures. The author conducted this pilot study to determine if treatments provided by DHATs differ significantly from those provided by dentists, to determine if DHATs in Alaska are delivering dental care within their scope of training in an acceptable manner and to assess the quality of care and incidence of reportable events during or after dental treatment.MethodsThe author audited the dental records of patients treated by dentists and DHATs who perform similar procedures for selected variables. He reviewed the records of 640 dental procedures performed in 406 patients in three health corporations.ResultsThe author found no significant differences among the provider groups in the consistency of diagnosis and treatment or postoperative complications as a result of primary treatment. The patients treated by DHATs had a mean age 7.1 years younger than that of patients treated by dentists, and the presence or adequacy of radiographs was higher among patients treated by dentists than among those treated by DHATs, with the difference being concentrated in the zero- to 6-year age group.ConclusionsNo significant evidence was found to indicate that irreversible dental treatment provided by DHATs differs from similar treatment provided by dentists. Further studies need to be conducted to determine possible long-term effects of irreversible procedures performed by nondentists.Clinical ImplicationsA need to improve oral health care for American Indian/Alaska Native populations has led to an approach for providing care to these groups in Alaska. The use of adequately trained DHATs as part of the dental team could be a viable long-term solution.     

The creation and development of the dental practice-based research network

BACKGROUND: Practice-based research networks (PBRNs) are consortia of practices committed to improving clinical practice. They have become more common and include dental PBRNs. Few reports in the literature, however, have addressed the structure and function of dental PBRNs. METHODS: After initial development in Alabama, the Dental Practice-Based Research Network (DPBRN) now includes practitioner-investigators in seven U.S. states and three Scandinavian countries. Although most of the function and structure was developed at the inception of DPBRN, valuable input from practitioner-investigators has led to significant ongoing refinements. RESULTS: DPBRN practitioner-investigators have contributed to research at each stage of its development, leading to substantial improvements in study designs and customization of study protocols to their daily clinical practices. Practitioner-investigators also have helped refine the structure and function of DPBRN to foster the potential impact of research. CONCLUSIONS: Practitioners from diverse settings are partnering with fellow practitioners and academics to improve daily clinical practice and meet the needs of clinicians and their patients in DPBRN. Practice Implications. Dental PBRNs can improve clinical practice by engaging dentists in the development and implementation of studies that are of direct interest to them and their patients, and by incorporating findings from these studies into their daily clinical practice.     

Factors associated with access to dental care for children with special health care needs

BACKGROUND: The authors examined the relationship between receipt of routine medical care and receipt of dental care among children with special health care needs (CSHCN) who resided in the American Dental Association's Fifth Trustee District, which includes Alabama, Georgia and Mississippi. METHODS: The authors conducted a cross-sectional study using data from the 2001 National Survey of Children with Special Health Care Needs, a module of that year's State and Local Area Integrated Telephone Survey (sponsored by the U.S. Department of Health and Human Services' Maternal and Child Health Bureau of the Health Resources and Service Administration, Rockville, Md., and conducted by the Centers for Disease Control and Prevention, Atlanta). The authors used bivariate and logistic regression analyses to explore the relationships (n = 2,092) between predisposing, enabling and need factors and receipt of dental care. RESULTS: The parents of an estimated 76 percent of CSHCN in the district reported that their child had a need for dental care in the previous 12 months. Of these, 13.1 percent did not receive care. Failure to obtain needed dental care was associated with failure to obtain routine medical care, as was having a lower income. CONCLUSIONS: Failure to obtain routine medical care may be a risk factor for failure to obtain dental care. Any income below 400 percent of the federal poverty guidelines appears to be a barrier to receiving dental care for CSHCN. PRACTICE IMPLICATIONS: Providers of routine medical care may play an important role in linking CSHCN to dental care. Investigators need to examine other barriers to dental care for CSHCN. Strategies to optimize access to dental care for CSHCN at all income levels are needed.     

Preventing dentists' involvement in torture: The developmental history of a new international declaration

BackgroundFor more than half a century, the risk of physicians participating in torture has received thoughtful attention in the field of medicine, and a number of international organizations have issued declarations decrying such involvement. Despite publications that provide evidence of dentists' having participated in torture as well, until recently the dental profession was quiescent on the subject.MethodsThe authors describe the historical background for a new declaration against dentists' participation in torture developed by the International Dental Ethics and Law Society and the Fédération Dentaire Internationale (FDI) World Dental Federation. They review various levels of involvement by dentists in torture and related activities in reference to existing World Medical Association declarations. Finally, they outline the process of drafting the new dental declaration, which was adopted by the FDI in October 2007.Clinical ImplicationsThe authors provide insight and guidance to clinicians who diligently serve their patients, unaware that they may face military or other pressures to participate in torture.     

Comparison of the intakes of sugars by young children with and without dental caries experience

BACKGROUND: Relationships among sugars and dental caries in contemporary societies are unclear. The authors describe young children's intakes of nonmilk extrinsic (NME) and intrinsic/milk sugars and relate those intakes to dental caries. METHODS: The authors conducted cross-sectional analyses of dietary data collected from the Iowa Fluoride Study using three-day diaries for subjects at ages 1, 2, 3, 4 and 5 years and for subjects aged 1 through 5 years according to dental caries experience at 4.5 to 6.9 years of age. They categorized foods and beverages as containing NME or intrinsic/milk sugars. RESULTS: Subjects' total, NME, food NME and intrinsic/milk sugars intakes at ages studied did not differ between subjects with and without caries experience. Beverage NME sugars intakes at age 3 years predicted caries (P < .05) in logistic regression models adjusted for age at dental examination and for fluoride intake. CONCLUSIONS: Dental caries is a complex, multifactorial disease process dependent on the presence of oral bacteria, a fermentable carbohydrate substrate and host enamel. A simple NME-intrinsic/milk sugars categorization appears insufficient to capture the complex dietary component of the caries process. CLINICAL IMPLICATIONS: Cariogenicity is more likely a function of the food and/or beverage vehicle delivering the sugar and the nature of exposure-that is, frequency and length of eating events-than of the sugar's categorization.     

Concordance between clinical practice and published evidence: Findings from The National Dental Practice-Based Research Network

BackgroundDocumenting the gap between what is occurring in clinical practice and what published research findings suggest should be happening is an important step toward improving care. The authors conducted a study to quantify the concordance between clinical practice and published evidence across preventive, diagnostic and treatment procedures among a sample of dentists in The National Dental Practice-Based Research Network (“the network”).MethodsNetwork dentists completed one questionnaire about their demographic characteristics and another about how they treat patients across 12 scenarios/clinical practice behaviors. The authors coded responses to each scenario/clinical practice behavior as consistent (“1”) or inconsistent (“0”) with published evidence, summed the coded responses and divided the sum by the number of total responses to create an overall concordance score. The overall concordance score was calculated as the mean percentage of responses that were consistent with published evidence.ResultsThe authors limited analyses to participants in the United States (N = 591). The study results show a mean concordance at the practitioner level of 62 percent (SD = 18 percent); procedure-specific concordance ranged from 8 to 100 percent. Affiliation with a large group practice, being a female practitioner and having received a dental degree before 1990 were independently associated with high concordance (≥ 75 percent).ConclusionDentists reported a medium-range concordance between practice and published evidence.Practical ImplicationsEfforts to bring research findings into routine practice are needed.     

A retrospective review of clinical international normalized ratio results and their implications

BackgroundWarfarin is a key element in therapy for atrial fibrillation, deep venous thrombosis (DVT), stroke (cerebrovascular accident) and cardiac valve replacement. Often, patients’ warfarin blood levels are not tightly controlled with regard to accepted therapeutic ranges, by virtue of the drug’s unpredictable nature.MethodsThe authors searched 16,017 active clinical charts for active patients of record from the three campuses of the School of Dentistry, Marquette University (MU), Milwaukee, for the years 2009 and 2010. Dental records of 315 patients contained entries including “INR,” the abbreviation for the term “international normalized ratio.” Only 247 of those records contained an indication of whether the patient’s INR values were within therapeutic range. The authors found that 1.96 percent of the total MU dental clinic patient population had a history of warfarin use.ResultsWhen the authors compared the INR values for patients with diagnoses of atrial fibrillation, DVT, stroke and cardiac valve replacement, they found that INR values for 107 of the 247 patients (43.3 percent) were not within therapeutic range for the respective diagnoses. For example, only 50 percent of the patients being treated for atrial fibrillation presented themselves for surgical dental treatment while their INR values were in tight control.ConclusionThe INR values for a significant number of dental patients are not within the therapeutic range for their medical conditions. These patients need to seek follow-up care from their medical care providers.Clinical ImplicationsScreening for INR in the dental office—especially before invasive dental treatment such as periodontal surgery, tooth extraction and dental implant placement—can help prevent postoperative complications. It also can aid the clinician in evaluating whether a patient’s INR is within therapeutic range and, subsequently, whether the patient’s physician needs to adjust the warfarin dosage.     

Hepatitis B virus transmissions associated with a portable dental clinic,West Virginia, 2009

BackgroundAlthough hepatitis B virus (HBV) transmission in dental settings is rare, in 2009 a cluster of acute HBV infections was reported among attendees of a two-day portable dental clinic in West Virginia.MethodsThe authors conducted a retrospective investigation by using treatment records and volunteer logs, interviews of patients and volunteers with acute HBV infection as well as of other clinic volunteers, and molecular sequencing of the virus from those acutely infected.ResultsThe clinic was held under the auspices of a charitable organization in a gymnasium staffed by 750 volunteers, including dental care providers who treated 1,137 adults. Five acute HBV infections—involving three patients and two volunteers—were identified by the local and state health departments. Of four viral isolates available for testing, all were genotype D. Three case patients underwent extractions; one received restorations and one a dental prophylaxis. None shared a treatment provider with any of the others. One case volunteer worked in maintenance; the other directed patients from triage to the treatment waiting area. Case patients reported no behavioral risk factors for HBV infection. The investigation revealed numerous infection control breaches.ConclusionsTransmission of HBV to three patients and two volunteers is likely to have occurred at a portable dental clinic. Specific breaches in infection control could not be linked to these HBV transmissions.Practical ImplicationsAll dental settings should adhere to recommended infection control practices, including oversight; training in prevention of bloodborne pathogens transmission; receipt of HBV vaccination for staff who may come into contact with blood or body fluids; use of appropriate personal protective equipment, sterilization and disinfection procedures; and use of measures, such as high-volume suction, to minimize the spread of blood.     

Foreign-trained dentists licensed in the United States: exploring their origins

BACKGROUND: The authors explored the origins of foreign-trained dentists seeking licensure in the United States. METHODS: The authors analyzed data received from the American Dental Association Department of Testing Services for candidates who took the National Board Dental Examinations (NBDE) Part II from 2002 through 2005. They also established proxies for the information they sought in lieu of existing direct data. RESULTS: A total of 4,136 candidates took NBDE Part II from 2002 through 2005. The greatest number of foreign-trained dentists originated from India, the Philippines and Colombia. CONCLUSION: The greatest number of potential U.S. dental licensees are primarily from Asia, the Middle East and South America. However, precise studies need to be conducted to generate more exact data about foreign-trained dentists who practice in the United States. CLINICAL IMPLICATIONS: The source of international dental graduates seeking licensure in the United States has implications for the licensure process and for the potential accreditation of foreign dental schools.     

The prevalence of caries and tooth loss among participants in the Hispanic Community Health Study/Study of Latinos

Background.The Hispanic and Latino population is projected to increase from 16.7 percent to 30.0 percent by 2050. Previous U.S. national surveys had minimal representation of Hispanic and Latino participants other than Mexicans, despite evidence suggesting that Hispanic or Latino country of origin and degree of acculturation influence health outcomes in this population. In this article, the authors describe the prevalence and mean number of cavitated, decayed and filled surfaces, missing teeth and edentulism among Hispanics and Latinos of different national origins.Methods.Investigators in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)—a multicenter epidemiologic study funded by the National Heart, Lung, and Blood Institute with funds transferred from six other institutes, including the National Institute of Dental and Craniofacial Research—conducted in-person examinations and interviews with more than 16,000 participants aged 18 to 74 years in four U.S. cities between March 2008 and June 2011. The investigators identified missing, filled and decayed teeth according to a modified version of methods used in the National Health and Nutrition Examination Survey. The authors computed prevalence estimates (weighted percentages), weighted means and standard errors for measures.Results.The prevalence of decayed surfaces ranged from 20.2 percent to 35.5 percent, depending on Hispanic or Latino background, whereas the prevalence of decayed and filled surfaces ranged from 82.7 percent to 87.0 percent, indicating substantial amounts of dental treatment. The prevalence of missing teeth ranged from 49.8 percent to 63.8 percent and differed according to Hispanic or Latino background. Significant differences in the mean number of decayed surfaces, decayed or filled surfaces and missing teeth according to Hispanic and Latino background existed within each of the age groups and between women and men.Conclusions.Oral health status differs according to Hispanic or Latino background, even with adjustment for age, sex and other characteristics.Practical Implications.These data indicate that Hispanics and Latinos in the United States receive restorative dental treatment and that practitioners should consider the association between Hispanic or Latino origin and oral health status. This could mean that dental practices in areas dominated by patients from a single Hispanic or Latino background can anticipate a practice based on a specific pattern of treatment needs.     

Advancing infection control in dental care settings: Factors associated with dentists' implementation of guidelines from the Centers for Disease Control and Prevention

Background and OverviewThe authors set out to identify factors associated with implementation by U.S. dentists of four practices first recommended in the Centers for Disease Control and Prevention's Guidelines for Infection Control in Dental Health-Care Settings—2003.MethodsIn 2008, the authors surveyed a stratified random sample of 6,825 U.S. dentists. The response rate was 49 percent. The authors gathered data regarding dentists' demographic and practice characteristics, attitudes toward infection control, sources of instruction regarding the guidelines and knowledge about the need to use sterile water for surgical procedures. Then they assessed the impact of those factors on the implementation of four recommendations: having an infection control coordinator, maintaining dental unit water quality, documenting percutaneous injuries and using safer medical devices, such as safer syringes and scalpels. The authors conducted bivariate analyses and proportional odds modeling.ResultsResponding dentists in 34 percent of practices had implemented none or one of the four recommendations, 40 percent had implemented two of the recommendations and 26 percent had implemented three or four of the recommendations. The likelihood of implementation was higher among dentists who acknowledged the importance of infection control, had practiced dentistry for less than 30 years, had received more continuing dental education credits in infection control, correctly identified more surgical procedures that require the use of sterile water, worked in larger practices and had at least three sources of instruction regarding the guidelines. Dentists with practices in the South Atlantic, Middle Atlantic or East South Central U.S. Census divisions were less likely to have complied.ConclusionsImplementation of the four recommendations varied among U.S. dentists. Strategies targeted at raising awareness of the importance of infection control, increasing continuing education requirements and developing multiple modes of instruction may increase implementation of current and future Centers for Disease Control and Prevention guidelines.The findings and conclusions in this report are those of the authors and do not necessarily represent the official position of the Centers for Disease Control and Prevention, Atlanta.The authors thank Jon Ruesch, who when this study was conducted was the director, Survey Center, American Dental Association, Chicago, for his effort in the collection of the data for this research project.

Restoration of noncarious tooth defects by dentists in The Dental Practice-Based Research Network

BackgroundThe authors conducted a study to quantify the reasons for restoring noncarious tooth defects (NCTDs) by dentists in The Dental Practice-Based Research Network (DPBRN) and to assess the tooth, patient and dentist characteristics associated with those reasons.MethodsData were collected by 178 DPBRN dentists regarding the placement of 1,301 consecutive restorations owing to NCTDs. Information gathered included the main clinical reason, other than dental caries, for restoration of previously unrestored permanent tooth surfaces; characteristics of patients who received treatment; dentists’ and dental practices’ characteristics; teeth and surfaces restored; and restorative materials used.ResultsDentists most often placed restorations to treat lesions caused by abrasion, abfraction or erosion (AAE) (46 percent) and tooth fracture (31 percent). Patients 41 years or older received restorations mainly because of AAE (P < .001). Premolars and anterior teeth were restored mostly owing to AAE; molars were restored mostly owing to tooth fracture (P < .001). Dentists used directly placed resin-based composite (RBC) largely to restore AAE lesions and fractured teeth (P < .001).ConclusionsAmong DPBRN practices, AAE and tooth fracture were the main reasons for restoring noncarious tooth surfaces. Pre-molars and anterior teeth of patients 41 years and older are most likely to receive restorations owing to AAE; molars are most likely to receive restorations owing to tooth fracture. Dentists restored both types of NCTDs most often with RBC.     

Sealants and dental caries: Insight into dentists’ behaviors regarding implementation of clinical practice recommendations

BackgroundThe authors conducted a qualitative study of private-practice dentists in their offices by using vignette-based interviews to assess barriers to the use of evidence-based clinical recommendations in the treatment of noncavitated carious lesions.MethodsThe authors recruited 22 dentists as a convenience sample and presented them with two patient vignettes involving noncavitated carious lesions. Interviewers asked participants to articulate their thought processes as they described treatment recommendations. Participants compared their treatment plans with the American Dental Association’s recommendations for sealing noncavitated carious lesions, and they described barriers to implementing these recommendations in their practices. The authors recorded and transcribed the sessions for accuracy and themes.ResultsPersonal clinical experience emerged as the determining factor in dentists’ treatment decisions regarding noncavitated carious lesions. Additional factors were lack of reimbursement and mistrust of the recommendations. The authors found that knowledge of the recommendations did not lead to their adoption when the recommendation was incongruent with the dentist’s personal experience.ConclusionsThe authors found that ingrained practice behavior based on personal clinical experience that differed substantially from evidence-based recommendations resulted in a rejection of these recommendations.Practical ImplicationsAttempts to improve the adoption of evidence-based practice must involve more than simple dissemination of information to achieve a balance between personal clinical experience and scientific evidence.     

Dental treatment intensity in frail older adults in the last year of life

BackgroundPalliative care focusing on pain and infection is recommended for patients who are terminally ill. It is difficult to implement this strategy in practice because of the lack of clear guidelines. The authors conducted a study to examine dental treatment provided to a group of long-term care (LTC) residents in the last year of life.MethodsThe authors retrospectively followed 197 LTC residents (60 years or older) in the last year of life to death. On the basis of the dental services patients received between the new patient examination and death, the authors categorized the patients into three groups: no care (NC), limited care (LC) and usual care (UC). The authors developed a multivariable continuation ratio logit model with shared regression coefficients across two logits to identify the factors associated with the end-of-life dental care pattern.ResultsThe authors found that 50.8 percent of the patients received NC before death. Among those who received treatment, 62.9 percent received UC, and 60.7 percent of the patients in the UC group had completed their treatment in the last three months of life. A three-month increment in survival and having dental insurance resulted in 1.74 (95 percent confidence interval [CI], 1.32–2.30) and 2.59 (95 percent CI, 1.03–6.52) times greater odds, respectively, of receiving some dental treatment before death. Neither survival nor dental insurance, however, was associated with dental care intensity in the last year of life (that is, UC versus LC).ConclusionsWhile most of the patients who were in the last year of life received insufficient dental care, comprehensive treatment was provided commonly to frail patients at the end of life, raising questions about quality of care.Practical ImplicationsPalliative oral health management needs to be revisited to improve quality of care for frail older adults at the end of life.     

Treating dental patients who use oral antithrombotic medication: a survey of dentists in the Netherlands

BackgroundFor many years, international guidelines have advised health care professionals not to adjust oral antithrombotic medication (OAM) regimens before invasive dental procedures. The authors conducted a study to examine the opinions of Dutch general dentists regarding the dental care of patients receiving treatment with these medications.MethodsThe authors invited via e-mail 1,442 general dentists in the Netherlands to answer a 20-item Internet-based questionnaire that they developed. Survey items consisted of questions about medical history taking, number of patients in the dental practice receiving OAM therapy, frequency of consulting with medical and dental colleagues and suggested dental treatment of patients during various invasive dental procedures.ResultsA total of 487 questionnaires were returned (response rate of 34 percent). The mean age of respondents was 47 years, and 77 percent were male. The majority of dentists responded that they obtain medical histories, but that they did not know how many of their patients were receiving OAM treatment. Dentists reported that they consult with medical colleagues frequently about antithrombotic medication. Ninety-one percent of respondents stated that they obtained their medical knowledge primarily in dental school. More than 50 percent of the dentists reported that they were not familiar with the international normalized ratio. The majority of dentists responded that they felt a need for clinical practice guidelines.ConclusionsAccording to the results of our survey, most dentists remain cautious when performing invasive dental procedures in patients who are treated with OAMs. Moreover, survey respondents tended to estimate that the risk of bleeding during dental procedures when OAM therapy is continued is higher than the risk of rethrombosis when use of antithrombotic medication is interrupted.Clinical ImplicationsA growing proportion of elderly patients and those with medically complex conditions are being treated in dental practices in the Netherlands. Consequently, more needs to be done to ensure that dentists are offered evidence-based guidance when treating patients who receive OAMs.     

Predoctoral teaching of temporomandibular disorders: a survey of U.S. and Canadian dental schools

BACKGROUND: In the United States and Canada, there are no specific curriculum guidelines for predoctoral dental education in the field of temporomandibular disorders (TMDs). This situation has the potential to cause confusion for new graduates. METHODS: The authors sent an 11-question survey regarding predoctoral teaching of TMDs to the appropriate faculty members in all U.S. and Canadian dental schools either electronically or via the postal service between June and December 2005. RESULTS: Predoctoral teaching of TMD--both didactic and clinical aspects--has progressed. Some schools, however, do not address these topics adequately, while others teach outdated concepts. CONCLUSIONS: Both qualitative and quantitative standards are needed to ensure that all predoctoral dental students learn about the diagnosis and treatment of nondental orofacial pain problems. Practice Implications. Owing to the lack of standardized predoctoral teaching of TMD, U.S. or Canadian patients with TMD or facial pain are at risk when seeking appropriate primary care for their problems.     

Chemomechanical caries removal in children: an operator's and pediatric patients' responses

BACKGROUND: This study investigated an operator's and pediatric patients' responses to chemo-mechanical caries removal (CMCR) versus the traditional method (TM) of caries removal using a handpiece and a round bur when treating dentinal-depth occlusal lesions with minimal enamel access in primary molars. METHODS: Data were collected from 50 children at baseline and before, during and after caries removal using CMCR or TM. The subjects in the CMCR group were on average younger than the subjects in the TM group and had more deep lesions. RESULTS: The operator rated CMCR as needing more clinical and technical effort and more total effort than TM. He was less satisfied with CMCR than with TM. Subjects in the CMCR group perceived the time needed for treatment as significantly longer than did the subjects in the TM group. Fear of the dentist decreased in subjects in the TM group from before to after the operative appointment, while it increased in subjects in the CMCR group. CONCLUSIONS: The authors found no direct advantage in using CMCR over using TM. CLINICAL IMPLICATIONS: CMCR cannot be recommended as an alternative to TM when treating dentinal depth occlusal lesions with minimal access in primary molars.
