Designing a safety checklist for dental implant placement: A Delphi study

BackgroundComplications during and after dental implant placement can be a hindrance to successful treatment. Checklists are emerging as useful tools in error reduction in various fields. The authors selected a Delphi panel to explore the appropriate clinical practices involved in implant placement, with the objective of formulating a safety checklist that would aid in reducing errors.MethodsThe authors administered a Delphi method survey to an expert panel of 24 board-certified periodontists to determine if consensus existed regarding the critical steps involved in implant placement. They defined consensus as 90 percent agreement among participants. Using the Delphi data, the authors designed a safety checklist for implant placement.ResultsThe panelists generated 20 consensus statements regarding essential steps in implant placement. The authors divided the statements into preoperative, intraoperative and postoperative phases. To determine the rationale for consensus decisions, the authors conducted a thematic qualitative analysis of responses to all open-ended questionnaire items, asking panel members how or why a particular procedure was performed.ConclusionThe panelists reached a consensus regarding the steps they considered critical in implant placement. Further research is needed to assess the acceptance and effectiveness of this type of checklist in a clinical setting.Practical ImplicationsThe authors developed a checklist that may be useful in reducing errors in placement of dental implants. If effective, this checklist ultimately will aid in minimizing risk and increasing implant success rates, especially for inexperienced practitioners, dental students, surgical residents and dental implant trainees (that is, dentists undergoing training to place implants through continuing education courses).     

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.     

Risk of adrenal crisis in dental patients: Results of a systematic search of the literature

BackgroundThe authors performed a systematic search of the literature to identify the frequency of, risk of experiencing and factors associated with adrenal crises in dental patients.MethodsThe authors searched PubMed and Ovid MEDLINE (1947-June 20, 2012) and Embase (1974-2012) for English-language articles related to cases of adrenal crisis in dentistry and extracted and analyzed data from the articles. The six authors determined whether the cases identified met a consensus definition of adrenal crisis.ResultsOf 148 articles identified in the initial screening, 34 articles were included in the final review, from which six cases met the criteria of adrenal crisis. The authors categorized four cases as “suggestive of adrenal crisis” and two cases as “consistent with adrenal crisis.” Risk factors were significant adrenal insufficiency, pain, infection, having undergone an invasive procedure, having received a barbiturate general anesthetic, and poor health status and stability at the time of presentation. The authors estimated risk to be less than one in 650,000 in patients with adrenal insufficiency.ConclusionsAdrenal crisis is rare in dental patients, with only six reports of it having been published in the past 66 years. Risk is associated with unrecognized adrenal insufficiency, poor health status and stability at the time of treatment, pain, infection, having undergone an invasive procedure and having received a barbiturate general anesthetic.Clinical ImplicationsRisk of adrenal crisis is reduced through proper evaluation of the patient, identification of risk factors and following appropriate preventive measures.     

Implications of medical screenings of patients arriving for dental treatment: The results of a comprehensive laboratory screening

BackgroundThe authors conducted medical laboratory screenings in a dental setting to determine the relationships between the laboratory test results and self-reported medical health findings.MethodsThe authors collected serum, urine and medical histories from 171 patients (116 [68 percent] women; mean age, 43.4 years) who arrived for dental treatment as a component of a clinical trial and performed complete blood cell counts, standard blood chemistry panels and urinalysis on the samples.ResultsThe authors found 414 abnormal laboratory test results (an average of 2.42 per patient). Eighty-three percent of participants had one or more abnormal test results, 83 percent had abnormal test results and did not indicate a relevant disease in their medical history, and 18 percent had laboratory test results outside the 99 percent reference range (that is, > three standard deviations from the mean). Abnormal test results were significantly associated with sex, age, race and medical history (P < .05). Abnormal test results associated with kidney disease were related to patients with cardiovascular disease and diabetes, as well as those who tended to be on average older than 50 years.ConclusionsThe high frequency of significant abnormal laboratory test results detected in this study suggests that many patients may be unaware of their medical statuses.Practical ImplicationsAbnormal laboratory test results are detected frequently in the serum and urine of patients arriving for dental treatment, which could indicate undiagnosed disease and less than optimal medical management.     

Predicting anxiety during dental treatment using patients'self-reports: less is more

BACKGROUND: Self-reported dental fear measures seldom are used in clinical practice to assess patients' fears. This study examined how well dental fear measures predicted anxious behaviors displayed during dental treatment. METHODS: One hundred eight adult patients (54 percent female) in a periodontology clinic completed several paper-and-pencil demographic, dental fear and general anxiety measures before treatment. Dental practitioners, blinded to their patients' responses, rated their patients' anxiety during treatment on a series of 100-millimeter visual analog scales. RESULTS: Higher Dental Fear Survey scores, younger age, more invasive treatment type and previous avoidance of dental care because of a bad experience all were predictive of greater observed anxiety. Neither self-reported nor observed anxiety was affected by previous experience with a particular practitioner or treatment. CONCLUSIONS: Dentists may assess patients' anxiety quickly and accurately with the Dental Fear Survey or a similar measure, as well as by asking patients about their current dental attendance and previous dental experiences.     

A pilot study of a chiropractic intervention for management of chronic myofascial temporomandibular disorder

BackgroundTemporomandibular pain has multiple etiologies and a range of therapeutic options. In this pilot study, the authors assessed the feasibility of conducting a larger trial to evaluate chiropractic treatment of temporomandibular disorders (TMDs).MethodsThe authors assigned 80 participants randomly into one of the following four groups, all of which included a comprehensive self-care program: reversible interocclusal splint therapy (RIST), Activator Method Chiropractic Technique (AMCT) (Activator Methods International, Phoenix), sham AMCT and self-care only. They made assessments at baseline and at month 2 and month 6, including use of the Research Diagnostic Criteria for Temporomandibular Disorders.ResultsThe authors screened 721 potential participants and enrolled 80 people; 52 participants completed the six-month assessment. The adjusted mean change in current pain over six months, as assessed on the 11-point numerical rating scale, was 2.0 (95 percent confidence interval, 1.1–3.0) for RIST, 1.7 (0.9–2.5) for self-care only, 1.5 (0.7–2.4) for AMCT and 1.6 (0.7–2.5) for sham AMCT. The authors also assessed bothersomeness and functionality.ConclusionsThe authors found the study design and methodology to be manageable. They gained substantial knowledge to aid in conducting a larger study. AMCT, RIST and self-care should be evaluated in a future comparative effectiveness study.Practical ImplicationsThis pilot study was a necessary step to prepare for a larger study that will provide clinicians with information that should be helpful when discussing treatment options for patients with TMD.     

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.     

Preventing percutaneous injuries among dental health care personnel

BACKGROUND: The Occupational Safety and Health Administration and the Centers for Disease Control and Prevention (CDC) recommend that health care personnel (HCP) adopt safer work practices and consider using medical devices with safety features. This article describes the circumstances of percutaneous injuries among a sample of hospital-based dental HCP and estimates the preventability of a subset of these injuries: needlesticks. METHODS: The authors analyzed percutaneous injuries reported by dental HCP in the CDC's National Surveillance System for Health Care Workers (NaSH) from December 1995 through August 2004 to describe the circumstances. RESULTS: Of 360 percutaneous injuries, 36 percent were reported by dentists, 34 percent by oral surgeons, 22 percent by dental assistants, and 4 percent each by hygienists and students. Almost 25 percent involved anesthetic syringe needles. Of 87 needlestick injuries, 53 percent occurred after needle use and during activities in which a safety feature could have been activated (such as during passing and handling) or a safer work practice used. CONCLUSIONS: NaSH data show that needlestick injuries still occur and that a majority occur at a point in the workflow at which safety syringes--in addition to safe work practices and recapping systems--could contribute to injury prevention. CLINICAL IMPLICATIONS: All dental practices should have a comprehensive written program for preventing needlestick injuries that describes procedures for identifying, screening and, when appropriate, adopting safety devices; mechanisms for reporting and providing medical follow-up for percutaneous injuries; and a system for training staff members in safe work practices and the proper use of safety devices.     

A usability evaluation of four commercial dental computer-based patient record systems

BackgroundThe usability of dental computer-based patient record (CPR) systems has not been studied, despite early evidence that poor usability is a problem for dental CPR system users at multiple levels.MethodsThe authors conducted formal usability tests of four dental CPR systems by using a purposive sample of four groups of five novice users. The authors measured task outcomes (correctly completed, incorrectly completed and incomplete) in each CPR system while the participants performed nine clinical documentation tasks, as well as the number of usability problems identified in each CPR system and their potential relationship to task outcomes. The authors reviewed the software application design aspects responsible for these usability problems.ResultsThe range for correctly completed tasks was 16 to 64 percent, for incorrectly completed tasks 18 to 38 percent and for incomplete tasks 9 to 47 percent. The authors identified 286 usability problems. The main types were three unsuccessful attempts, negative affect and task incorrectly completed. They also identified six problematic interface and interaction designs that led to usability problems.ConclusionThe four dental CPR systems studied have significant usability problems for novice users, resulting in a steep learning curve and potentially reduced system adoption.Clinical ImplicationsThe significant number of data entry errors raises concerns about the quality of documentation in clinical practice.     

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.

Effectiveness of a resin-modified glass ionomer liner in reducing hypersensitivity in posterior restorations: A study from the Practitioners Engaged in Applied Research and Learning Network

BackgroundThe objectives of this randomized comparative effectiveness study conducted by members of the Practitioners Engaged in Applied Research and Learning (PEARL) Network were to determine whether using a resin-modified glass ionomer (RMGI) liner reduces postoperative hypersensitivity (POH) in dentin-bonded Class I and Class II resin-based composite (RBC) restorations, as well as to identify other factors (putative risk factors) associated with increased POH.MethodsPEARL Network practitioner-investigators (P-Is) (n = 28) were trained to assess sensitivity determination, enamel and dentin caries activity rankings, evaluation for sleep bruxism, and materials and techniques used. The P-Is enrolled 341 participants who had hypersensitive posterior lesions. Participants were randomly assigned to receive an RBC restoration with or without an RMGI liner before P-Is applied a one-step, self-etching bonding agent. P-Is conducted sensitivity evaluations at baseline, at one and four weeks after treatment, and at all visits according to patient-reported outcomes.ResultsP-Is collected complete data regarding 347 restorations (339 participants) at baseline, with 341 (98 percent) (333 participants) recalled at four weeks. Treatment groups were balanced across baseline characteristics and measures. RBC restorations with or without an RMGI liner had the same one-week and four-week POH outcomes, as measured clinically (by means of cold or air stimulation) and according to patient-reported outcomes.ConclusionsUse of an RMGI liner did not reduce clinically measured or patient-reported POH in moderate-depth Class I and Class II restorations. Cold and air clinical stimulation findings were similar between groups.Practical Implications. The time, effort and expense involved in placing an RMGI liner in these moderate-depth RBC restorations may be unnecessary, as the representative liner used did not improve hypersensitivity outcomes.     

The effect of dental sealants on bacteria levels in caries lesions: a review of the evidence

BACKGROUND: Concern about inadvertently sealing over caries often prevents dentists from providing dental sealants. The objective of the authors' review was to examine the effects of sealants on bacteria levels within caries lesions under dental sealants. METHODS: The authors searched electronic databases for comparative studies examining bacteria levels in sealed permanent teeth. To measure the effect of sealants on bacteria levels, they used the log(10) reduction in mean total viable bacteria counts (VBC) between sealed and not-sealed caries and the percentage reduction in the proportion of samples with viable bacteria. RESULTS: Six studies--three randomized controlled trials, two controlled trials and one before-and-after study-were included in the analysis. Although studies varied considerably, there were no findings of significant increases in bacteria under sealants. Sealing caries was associated with a 100-fold reduction in mean total VBC (four studies, 138 samples). Sealants reduced the probability of viable bacteria by about 50.0 percent (four studies, 117 samples). CONCLUSIONS: The authors found that sealants reduced bacteria in carious lesions, but that in some studies, low levels of bacteria persisted. These findings do not support reported concerns about poorer outcomes associated with inadvertently sealing caries. CLINICAL IMPLICATIONS: Practitioners should not be reluctant to provide sealants-an intervention proven to be highly effective in preventing caries-because of concerns about inadvertently sealing over caries.     

Metabolic syndrome: pathogenesis, medical care and dental implications

BACKGROUND: The dental literature contains little information about metabolic syndrome (MetS) and its dental implications. TYPES OF STUDIES REVIEWED: The authors conducted a MEDLINE search for the period 2000 through 2005, using the term "metabolic syndrome" to define its pathophysiology, medical treatment and dental implications. RESULTS: MetS is the co-occurrence of abdominal obesity, hyper-triglyceridemia, reduced high-density lipoprotein cholesterol levels, hypertension and impaired fasting glucose, which results from consumption of a high-calorie diet and decreased levels of physical activity superimposed on the appropriate genetic setting. Components of MetS synergistically promote the development of atherosclerosis, resulting in myocardial infarction and stroke. CLINICAL IMPLICATIONS: Deteriorating oral health status is associated with worsening of the atherogenic profile. Tooth loss often results in chewing difficulties because of inadequate occlusive surfaces and may lead to alterations in food selection and dietary quality. This, in turn, adversely affects body composition and nutritional status, both of which are related to vascular health. Dentists should develop treatment plans that preserve and restore the dentition, thus ensuring maximum masticatory efficiency and affording patients the optimum opportunity to consume food that will not foster atherogenesis.     

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.     

Craniofacial pain as the sole symptom of cardiac ischemia: a prospective multicenter study

BACKGROUND: Craniofacial pain can be the only symptom of cardiac ischemia. Failure to recognize its cardiac source can put the patient's life at risk. The authors conducted a study to reveal the prevalence of, the distribution of and sex differences regarding craniofacial pain of cardiac origin. METHODS: The authors prospectively selected consecutive patients (N = 186) who had had a verified cardiac ischemic episode. They studied the location and distribution of craniofacial and intraoral pain in detail. RESULTS: Craniofacial pain was the only complaint during the ischemic episode in 11 patients (6 percent), three of them who had acute myocardial infarction (AMI). Another 60 patients (32 percent) reported craniofacial pain concomitant with pain in other regions. The most common craniofacial pain locations were the throat, left mandible, right mandible, left temporomandibular joint/ear region and teeth. Craniofacial pain was pre-ponderantly manifested in female subjects (P = .031) and was the dominating symptom in both sexes in the absence of chest pain. CONCLUSIONS: Craniofacial pain commonly is induced by cardiac ischemia. This must be considered in differential diagnosis of toothache and orofacial pain. CLINICAL IMPLICATIONS: Because patients who have AMI without chest pain run a higher risk of experiencing a missed diagnosis and death, the dentist's awareness of this symptomatology can be crucial for early diagnosis and timely treatment.
