Updated recommendations for managing the care of patients receiving oral bisphosphonate therapy: An advisory statement from the American Dental Association Council on Scientific Affairs

Background and OverviewIn 2005, the American Dental Association (ADA) Council on Scientific Affairs convened an expert panel to develop clinical recommendations for dentists treating patients who are receiving oral bisphosphonate therapy. The Journal of the American Dental Association published the resulting report in 2006. This 2008 advisory statement is the first of projected periodic updates of the 2006 clinical recommendations.ConclusionThis 2008 advisory statement concludes, on the basis of a review of the current literature, that for patients receiving bisphosphonate therapy, the risk of developing bisphosphonate-associated osteonecrosis (BON) of the jaw apparently remains low. It also newly concludes that current screening and diagnostic tests are unreliable for predicting a patient's risk of developing the condition. This statement updates the 2006 recommendations regarding general dentistry, management of periodontal diseases, implant placement and maintenance, oral and maxillofacial surgery, endodontics, restorative dentistry and prosthodontics, and orthodontics.     

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.     

Dental findings and management in a child with hypomelanosis of Ito

Hypomelanosis of Ito (HI) is a rare neuroectodermal disorder characterized by hypopigmented whorls of skin along the Blaschko lines. Mental retardation and intractable epilepsy are also commonly observed in HI. However, there are only a few published reports describing dental observations in HI patients. Here, we report the oral management and novel dental findings of a male HI patient aged 3 years and 10 months. The chief complaint was spontaneous gingival bleeding due to gingival hyperplasia induced by anticonvulsants, which was improved with plaque control and gingival massage. Numerous additional dental abnormalities were also evident, including enamel hypoplasia and large pulpal chambers.     

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.

Dental arcade arteriovenous fistulas: From diagnosis to treatment with emphasis on the role of endovascular or percutaneous treatment: Single centre experience

ObjectiveDental arcade arteriovenous fistula (DA-AVF) are rare. The purpose of this study was to understand the angioarchitecture of these lesions, changing strategies of endovascular treatment and to analyse the best therapeutic option which will allow normal skeletal development especially in children.Materials and methodsRetrospective study of all the patients of DA-AVF managed at our centre over the last 16 years. Detailed analysis of the clinical features, the imaging findings, endovascular treatment and angiographic outcomes was done.ResultsTotal of six patients were treated. 5 were in the mandible and one in the maxilla. Transarterial glue embolization was done in 3 patients and direct puncture of the intraosseous venous pouch in 2. Transarterial Onyx was used in 2 patients through dual lumen balloon catheter. Overall cure was achieved in 5 out of 6 patients (83%).ConclusionHigh index of suspicion is required to diagnose it on panoramic radiographs. CT/MR/CTA can lead to early diagnosis. Transarterial Onyx embolization using dual lumen balloon catheter is a promising technique & allows excellent penetration of Onyx into the intraosseous venous pouch.     

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.     

Adverse events associated with chlorhexidine use: results from the Department of Veterans Affairs Dental Diabetes Study

BACKGROUND: The authors report adverse events (AEs) related to the use of chlorhexidine gluconate mouthrinse in a clinical trial of the efficacy of periodontal treatment in older adults with diabetes. METHODS: Participants were U.S. veterans with uncontrolled diabetes (hemoglobin A(1c) value > or =8.5 percent) and periodontal disease. Treatment included periodontal scaling, 0.12 percent chlorhexidine lavage during ultrasonic scaling and use of chlorhexidine mouthrinse at home. RESULTS: Forty-four (31 percent) of 140 subjects reported having AEs. Most common were taste changes and tooth staining, sore mouth and/or throat, tongue irritation and wheezing/shortness of breath; the latter was reported more commonly before chlorhexidine use than after. Only body mass index greater than 30 was significantly related to AEs. CONCLUSIONS: AEs are common among subjects using chlorhexidine mouthrinse. Most AEs (taste change and staining) were resolved easily by subjects' discontinuing mouthrinse use and receiving dental prophylaxis. No serious AEs were reported. CLINICAL IMPLICATIONS: Clinicians should advise patients using chlorhexidine mouthrinse of possible side effects. If necessary, patients should discontinue mouthrinse use and obtain medical care. Careful monitoring of AEs in patients using chlorhexidine is warranted.     

At-home oral care for adults with developmental disabilities: A survey of caregivers

BackgroundLittle is known about effective at-home oral care methods for people with developmental disabilities (DDs) who are unable to perform personal preventive practices themselves and rely on caregivers for assistance.MethodsA convenience sample of 808 caregivers (84.5 percent paid, 15.5 percent family members) who accompanied adults with DDs (20 years or older) to appointments at a specialized statewide dental care system completed computer-assisted personal interview surveys. The authors used these data to investigate caregivers' at-home oral care experiences and to explore differences between caregivers who were paid and those who were family members.ResultsCaregivers reported that a high proportion (85 percent) of dentate adults with DDs received assistance with tooth cleaning. They also reported a high prevalence of dental problems, and low adherence to brushing (79 percent) and flossing (22 percent) recommendations. More caregivers reported that they felt confident assisting with brushing than with flossing (85 percent versus 54 percent). Family members and paid caregivers differed with respect to confidence and training.ConclusionsAt-home oral care, particularly flossing, presents substantial challenges for adults with DDs. Solutions must be tailored to address the different experiences and distinct needs of the family members and paid caregivers who assist these adults.Practical ImplicationsCaregivers play an important role in providing at-home oral care, and they must be included in efforts to improve oral health outcomes for people with DDs.     

Cost-effectiveness of treatments for temporomandibular disorders: biopsychosocial intervention versus treatment as usual

BACKGROUND: The authors conducted a randomized clinical trial to evaluate the cost-effectiveness of a biopsychosocial intervention with patients who are at high risk (HR) of progressing from acute to chronic TMD-related pain. METHODS: The authors classified 96 patients with acute TMD (less than six months' duration) as HR according to a predictive algorithm and randomized them into an early intervention (EI) or a nonintervention (NI) group. The NI group received a biopsychosocial treatment that included cognitive behavioral skills training and biofeedback. Both groups were followed up for one year. The authors collected TMD cost data throughout the year. RESULTS: The authors found that the EI group spent significantly fewer jaw-related health care dollars, relative to the NI group, from intake to the one-year follow-up. CONCLUSION AND CLINICAL IMPLICATIONS: The reduced jaw-related health care expenditures for patients in the EI group compared with expenditures for patients in the NI group at one year suggest that an early biopsychosocial intervention is a cost-effective measure in dealing with often unnecessarily costly TMD-related pain.

The Dental Practice-Based Research Network (DPBRN) provided a means to investigate whether certain procedures were performed routinely. The authors conducted a study to quantify rubber dam use during root canal treatment (RCT) among general dentists and to test the hypothesis that certain dentist or practice characteristics were associated with rubber dam use.MethodsDPBRN practitioner-investigators (P-Is) answered a questionnaire that included items about rubber dam use and other forms of isolation during RCT. DPBRN enrollment questionnaire data provided information regarding practitioner and practice characteristics.ResultsA total of 729 (74 percent) of 991 P-Is responded; 524 were general dentists who reported providing at least some RCTs and reported the percentage of RCTs for which they used a rubber dam. Of these 524 P-Is, 44 percent used a rubber dam for all RCTs, 24 percent used it for 51 to 99 percent of RCTs, 17 percent used it for 1 to 50 percent of RCTs, and 15 percent never used it during RCT. Usage varied significantly by geographic region and practice type. The use of cotton rolls and other forms of isolation also was reported.ConclusionsSimilar to other reports in the literature, not all DPBRN general dentists used a rubber dam during RCT.Clinical ImplicationsBecause the clinical reference standard is to use a rubber dam during RCT, increasing its use may be important.     

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.     

Twenty-month follow-up of occlusal caries lesions deemed questionable at baseline: Findings from The National Dental Practice-Based Research Network

Background.A questionable occlusal caries (QOC) lesion can be defined as an occlusal surface with no radiographic evidence of caries, but caries is suspected because of clinical appearance. In this study, the authors report the results of a 20-month follow-up of these lesions.Methods.Fifty-three clinicians from The National Dental Practice-Based Research Network participated in this study, recording lesion characteristics at baseline and lesion status at 20 months.Results.At baseline, 1,341 QOC lesions were examined; the treatment that was planned for 1,033 of those at baseline was monitoring (oral hygiene instruction, applying or prescribing fluoride or varnish, or both), and the remaining 308 received a sealant (n = 192) or invasive therapy (n = 116). At the 20-month visit, clinicians continued to monitor 927 (90 percent) of the 1,033 monitored lesions. Clinicians decided to seal 61 (6 percent) of the 1,033 lesions (mean follow-up, 19 months) and invasively treat 45 (4 percent) of them (mean follow-up, 15 months). Young patient age (< 18 years) (odds ratio = 3.4; 95 percent confidence interval, 1.7-6.8) and the lesion&apos;s being on a molar (odds ratio = 1.8; 95 percent confidence interval, 1.3-2.6) were associated with the clinician&apos;s deciding at some point after follow-up to seal the lesion or treat it invasively.Conclusions.Almost all (90 percent) QOC lesions for which the treatment planned at baseline was monitoring still were planned to undergo monitoring after 20 months. This finding suggests that noninvasive management is appropriate for these lesions.Practical Implications.Previous study results from baseline indicated a high prevalence of QOC lesions (34 percent). Clinicians should consider long-term monitoring when making treatment decisions about these lesions.     

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.
