Adoption and Effect of Sealants for Occlusal Noncavitated Caries in a Large Dental Network in the USA.

INTRODUCTION: Dental sealants applied to occlusal pit-and-fissure surfaces have been shown to prevent caries and arrest occlusal noncavitated carious lesions (NCCLs). The American Dental Association (ADA) recommends that oral healthcare providers apply sealants on occlusal NCCLs. Though the evidence is clear that sealants are effective, few studies have examined the adoption of the ADA guideline by dentists and the duration of protection provided by sealants in a large real-world setting. METHODS: This study used observational electronic health record (EHR) data from a network of dental clinics to follow teeth over a 2 year time period from when they were diagnosed as having an occlusal NCCL until either they were treated with a restoration or the time period ended with no restoration. The objectives of the study were to determine: (1) the degree to which dentists adopted the guideline, (2) whether the duration of protection was different for teeth that received a sealant from teeth that did not receive a sealant, and (3) whether dentists' experience placing sealants was associated with the duration of protection. RESULTS: Overall, there were 7,299 teeth in the sample. Of those, dentists restored 591 teeth and applied sealants on 164. The sealant application rate for eligible teeth was 2.2%. Sealant application was associated with provider, with 1.9% of providers placing more than half of the sealants. By the end of the observation period, the proportion of teeth progressing to restorations was 8.2% for teeth that had not received a sealant and 3.0% for teeth that had received one (RR = 0.37; 95% CI: 0.16-0.88; p = 0.02). Multilevel survival analysis showed that teeth that had not received a sealant were restored sooner than teeth that had received a sealant (aHR = 0.11; 95% CI: 0.03-0.36; p < 0.01). Overall, teeth that received a sealant had an 89% reduced hazard of restoration within 2 years compared with teeth that did not receive sealants. CONCLUSION: This study found that by arresting decay, the presence of sealants led to fewer restorations and delayed restorations compared with teeth not receiving a sealant or restoration in the 2 years following diagnosis of occlusal NCCL in clinical settings.

Protraction Headgear Compliance and Orthognathic Surgery in Patients With Cleft Lip and Palate.

Assess cephalometric parameters and the need for orthognathic surgery (OS) and its relationship with compliance in protraction headgear (PHG).Retrospective case series.Hospital cleft-craniofacial center.23 patients with nonsyndromic cleft lip and palate and history of lip and palate repair.Patients received PHG and orthodontic treatment. Compliant patients were compared to patients that were not. Protraction was applied with 170-gram elastics and patients were instructed to wear for at least 12 hours daily.Cephalometric measurements at initial (T1), post-PHG (T2), and pre-surgical or post-orthodontic treatment (T3) of at least age 15 for females and 17 for males and the presence of OS were compared.83% (19) of patients reported compliance with therapy. Of those compliant, 68% (13) had OS and 32% (6) did not (P = .99). Inter-group comparisons at T1 between compliant and noncompliant showed no significant differences and the non-OS patients started with larger nasolabial angles (P < .05). At T2, there were no significant cephalometric differences between groups. At T3, compliant patients showed significantly more upper incisor proclination than noncompliant patients. Between OS and non-OS, OS patients had significantly decreased ANB, Wits, convexity, overjet, and FMA and larger nasolabial angles (P < .05).Patients compliant with PHG showed no difference in the need for OS. However, after orthodontic treatment, compliant patients showed more upper incisor proclination and OS patients with decreased ANB, Wits, convexity, overjet, FMA, and larger nasolabial angles.

Digital intraoral imaging: analysis of retakes and reduction in radiation exposure using rectangular collimation.

The purposes of this study were to examine the distribution and extent of retakes with digital intraoral imaging when operators transitioned from using round to rectangular collimators and to determine the effect of collimator shape on radiation exposure to patients. This study was conducted using digital intraoral radiographic data from 2018 to 2019 in a dental school radiology clinic. Digital intraoral radiography was performed with round collimators during 2018 and then with rectangular collimators in 2019 with the same cohort of students. Exposure values were obtained, and effective doses were calculated. Although the number of retakes increased with the transition from round to rectangular collimators, the transition also resulted in a statistically significant reduction in the overall effective dose for patients (P < 0.01; Pearson chi-square test), with an average difference of 60% between round and rectangular collimators. Even with the increase in the number of retakes, a decrease in effective dose was observed when rectangular collimation was used. Most retakes were due to placement errors, defined as missing contact points, missing apices of teeth, or a missing area of interest. As students gained more experience and practice with rectangular collimation, the number of retakes decreased. With proper clinical and didactic training and emphasis on the importance of rectangular collimation, a transition from round to rectangular collimation can be achieved with a minimal initial increase in retakes and subsequent normalization of rates, resulting in a significant reduction of the radiation dose to patients.

Cone-Beam Computed Tomography Incidental Findings in Individuals With Cleft Lip and Palate.

OBJECTIVES: The use of cone-beam computed tomography (CBCT) is well-established in clinical practice. This study seeks to categorize and quantify the incidental finding (IF) rate on CBCT in patients with cleft lip and palate (CLP) prior to orthodontic or surgical treatment. METHODS: This is systematic retrospective review of head and neck CBCTs in patients with nonsyndromic CLP taken between 2012 and 2019 at a single tertiary referral center. All assessments were performed independently by 4 observers (a head and neck radiologist and 3 orthodontists, including 2 fellowship-trained cleft-craniofacial orthodontists ). The images were divided into 9 anatomical areas and screened using serial axial slices and 3D reconstructions. The absolute number of IFs was reported for each area and statistical analysis was performed. RESULTS: Incidental findings were found in 106 (95.5%) of the 111 patients. The most common sites were the maxilla (87.4%, principally dental anomalies), paranasal sinuses (46.8%, principally inflammatory opacification), and inner ear cavities (18.9%, principally inflammatory opacification). Eleven patients had skull malformations. Thirty-three patients had IFs in 1 anatomical area, 49 patients in 2 anatomical areas, 19 patients in 3 areas, and 5 patients presented with IFs in 4 of the 9 anatomical areas. DISCUSSION: In patients with CLP, IFs on CBCT exam were present in the majority of cases. Most patients with IFs had them in multiple anatomical areas of the head and neck. The maxillary dental-alveolar complex was the most common area. Inflammatory changes in the inner ear cavities and paranasal sinuses were also common; however, cervical spine and skull abnormalities were also identified. Clinicians caring for patients with CLP should be aware of IFs, which may warrant further investigation and treatment.

Barriers to sealant guideline implementation within a multi-site managed care dental practice.

BACKGROUND: The purpose of this study was to identify barriers frequently endorsed by dentists in a large, multi-site dental practice to implementing the American Dental Association's recommendation for sealing noncavitated occlusal carious lesions as established in their 2016 pit-and-fissure sealant clinical practice guideline. Although previous research has identified barriers to using sealants perceived by dentists in private practice, barriers frequently endorsed by dentists in large, multi-site dental practices have yet to be identified. Identifying barriers for these dentists is important, because it is expected that in the future, the multi-site group practice configuration will comprise more dental practices. METHODS: We anonymously surveyed the 110 general and pediatric dentists at a multi-site dental practice in the U.S. The survey assessed potential barriers in three domains: practice environment, prevailing opinion, and knowledge and attitudes. Results were summarized using descriptive statistics. RESULTS: The response rate to the survey was 62%. The principal barrier characterizing the practice environment was concern regarding liability; endorsed by 33% of the dentists. Many barriers of prevailing opinion were frequently endorsed. These included misunderstanding the standard of practice (59%), being unaware of the expectations of opinion leaders (56%) including being unaware of the guideline itself (67%), and being unaware of what is currently being taught in dental schools (58%). Finally, barriers of knowledge and attitudes were frequently endorsed. These included having suboptimal skill in applying sealants (23% - 47%) and lacking knowledge regarding the relative efficacy of the different ways to manage noncavitated occlusal carious lesions (50%). CONCLUSIONS: We identified barriers frequently endorsed by dentists in a large, multi-site dental practice relating to the practice environment, prevailing opinion, and knowledge and attitudes. All the barriers we identified have the potential to be addressed by implementation strategies. Future studies should devise and test implementation strategies to target these barriers.

A comparison of crown preparation grading via PrepCheck versus grading by dental school instructors.

Recent reports in the literature demonstrate the influence that digital dentistry is having on the preclinical training of dental students. However, none of these articles have discussed the use of PrepCheck (Sirona Dental Systems) in the evaluation of preparation taper in a preclinical environment. The present study compared the subjective grading of student tooth preparations by experienced, well-calibrated faculty with objective digital grading of the same preparations by means of the PrepCheck software. Sixty-nine sophomore dental student preparations were first subjectively graded by their dental instructors, and then the preparations were evaluated by the PrepCheck software. Neither the students nor the instructors were aware that the second PrepCheck evaluation was going to occur. The statistically significant results of this study conclude that the subjective instructor grades were inflated compared with the digital PrepCheck grades. The inflated grading by the instructors may give students a sense that their progress is better than it actually is. The objective, exact nature of the PrepCheck evaluation gives students immediate feedback regarding their preclinical preparations. Although taper was the only parameter examined in this study, PrepCheck allows the operator to examine many other features of a student's preparation. Also made evident in this study is the fact that the present standard for preparation taper is unattainable in a preclinical environment and needs to be readjusted to a wider, attainable range.

Trajectories of opioid prescribing by general dentists, specialists, and oral and maxillofacial surgeons in the United States, 2015-2019.

BACKGROUND: Despite decreases in opioid prescribing from 2016 through 2019, some dentists (general, specialists, oral and maxillofacial surgeons) in the United States continue to prescribe opioids at high rates. The authors' objective was to define dentists' trajectories of opioid prescribing. METHODS: The authors identified actively prescribing dentists from the IQVIA Longitudinal Prescription data set, from 2015 through 2019. Group-based trajectory modeling identified opioid prescribing trajectories on the basis of dentists' annual prescribing rates for the overall sample (model 1) and for high prescribers (model 2). The authors used χ2 or Mann-Whitney U tests to characterize the model 2 trajectory groups. RESULTS: In model 1 (n = 199,145 prescribers), group-based trajectory modeling identified 8 trajectories that were grouped into 5 categories. A total of 14.8% were nonprescribers who composed less than 1% of all prescriptions, low prescribers (3 groups; 46.0%) prescribed at low rates (2015: 5.5%-16.9%; 2019: 1.5%-11.9%), decliners (7.3%) decreased prescribing rapidly (2015: 29.4%; 2019: 5.1%), moderately high prescribers (2 groups; 28.5%) prescribed moderately (2015: 28.7% and 39.2%; 2019: 18.1% and 28.8%), and consistently high prescribers (3.4%) prescribed at high rates (2015: 54.6%; 2019: 44.7%). In model 2, from consistently high prescribers (n = 6,845), 4 trajectories were identified. Of these 4 groups, 1 group (7.5%) declined prescribing rapidly. The groups did not differ meaningfully; however, the rapid decliners included fewer oral and maxillofacial surgeons (13.0% vs 18.4%), saw more Medicaid patients (2.5% vs 1.0%), and had higher opioid prescribing rates in 2015 (95.5% vs 91.6%) (P < .001 for all). CONCLUSIONS: The authors identified variations in dentists' opioid prescribing rates. Although 60% of dentists decreased prescribing rates by 30% through 83%, 3.4% of dentists consistently prescribed at high rates. PRACTICAL IMPLICATIONS: Some dentists continue to prescribe opioids at high levels, indicating that additional information is needed to better inform policy and clinical decision making.

Testing a Deliberative Democracy Engagement Intervention to Increase Guideline-Concordance Among Oral Health Providers: Results from the DISGO Cluster-Randomized, Stepped-Wedge Trial.

Background: Dental caries affects billions worldwide and in the U.S. is among the most prevalent noncommunicable diseases in both children and adults. Early in the caries process, it can be arrested by dental sealants, which are non-invasive and thus tooth sparing, however, few dentists have adopted this approach. Deliberative engagement processes enable participants to engage with diverse perspectives on a policy issue and develop and share with policy makers informed opinions about the policy issue. We examined the effects of a deliberative engagement process on the ability of oral health providers to endorse implementation interventions and to apply dental sealants. Methods: Using a stepped wedge design, 16 dental clinics were cluster randomized, and 680 providers and staff were exposed to a deliberative engagement process that included an introductory session, workbook, facilitated small group deliberative forum, and post-forum survey. Forum participants were assigned to forums to ensure diverse role representation. Mechanisms of action examined included sharing voice and diversity of opinion. Three months after each clinic's forum, the clinic manager was interviewed about implementation interventions deployed. There were 98 clinic-months in the non-intervention period and 101 clinic-months in the intervention period. Results: Compared with providers and staff in small clinics, providers and staff in medium and large clinics more strongly agreed that their clinic should adopt two of the three proposed implementation interventions targeting the first barrier and one of the two proposed implementation interventions targeting the second barrier. Compared with the non-intervention period, in the intervention period providers did not place more sealants on occlusal non-cavitated carious lesions. Survey respondents reported sharing both promotive and prohibitive voice. From the beginning to the end of the forums, most forum participants did not change their opinions about the possible implementation interventions. At the end of the forums, there was no significant within-group variability in implementation interventions endorsed. Conclusions: Deliberative engagement intervention may help clinic leadership identify implementation interventions when there is a challenging problem, a network of semi-autonomous clinics, and autonomous providers within those clinics. It remains to be determined whether there is a range of perspectives within clinics. Trial Registration: This project is registered at ClinicalTrials.gov with ID NCT04682730. The trial was first registered on 12/18/2020. https://clinicaltrials.gov/ct2/show/NCT04682730.

History of dysplasia and primary site associated with recurrence in T1N0 oral squamous cell carcinoma.

OBJECTIVE: Recurrent disease occurs in a significant proportion of early-stage oral squamous cell carcinoma (OSCC) despite removal of the entire tumor with clear surgical margins. Our study sought to identify clinicopathologic factors that increase the risk of locoregional recurrence in T1N0 OSCC. STUDY DESIGN: We conducted an observational retrospective analysis of 65 cases of T1N0 OSCC over a period of 13 years. For each case, we examined the clinical presentation, histopathologic appearance, and treatment characteristics of interest to evaluate the association between these variables and locoregional recurrence. RESULTS: The 5-year and 10-year locoregional recurrence rates were 29.2% and 33.8%, respectively. Individuals with prior oral dysplasia had significantly higher odds for locoregional recurrence (P < .01) and reduced 5-year disease-free survival rates (P < .01). OSCC of the tongue and floor of the mouth had lower recurrence odds than carcinomas of the gingiva, buccal mucosa, and palate (P < .05). Histologic grade (P = .80), depth of invasion (P = .82), and elective neck dissection (P = .80) did not appear to influence locoregional recurrence for T1N0 tumors. CONCLUSIONS: Given the morbidity and mortality associated with OSCC, understanding of the clinicopathologic factors associated with recurrent disease may lead to improved treatment and follow-up protocols for a subset of early-stage patients.

Study protocol: A stepped-wedge, cluster-randomized trial of the effectiveness of a deliberative loop in identifying implementation strategies for the adoption of a dental sealant guideline in dental clinics.

BACKGROUND: The American Dental Association (ADA) recommends dental providers apply dental sealants to the occlusal surfaces of permanent molars for the prevention or treatment of non-cavitated dental caries. Despite the evidence-based support for this guideline, adherence among general dentists is low, ranging from less than 5 to 38.5%. Thus, an evidence-to-practice gap exists, and it is unclear which implementation strategies would best support providers in adopting and implementing the evidence-based practice. One potential approach to selecting and tailoring implementation strategies is a deliberative loop process, a stakeholder-engaged approach to decision-making. This trial aims to test the acceptability, feasibility, and effectiveness of using a deliberative loop intervention with stakeholders (i.e., providers and staff) to enable managers to select implementation strategies that facilitate the adoption of an evidence-based dental practice. METHODS: Sixteen dental clinics within Kaiser Permanente Northwest Dental will be cluster randomized to determine the timing of receiving the intervention in this stepped-wedge trial. In the three-part deliberative loop intervention, clinic stakeholders engage in the following activities: (1) receive background information, (2) participate in facilitated small-group discussions designed to promote learning from each other's lived experiences and develop informed opinions about effective clinic-level implementation strategies, and (3) share their informed opinions with clinic leaders, who may then choose to select and deploy implementation strategies based on the stakeholders' informed opinions. The primary outcome of Reach will be defined as patient-level receipt of guideline-concordant care. Secondary outcomes will include the cost-effectiveness, acceptability, and feasibility of the deliberative loop process. Implementation strategies deployed will be catalogued over time. DISCUSSION: These results will establish the extent to which the deliberative loop process can help leaders select and tailor implementation strategies with the goal of improving guideline-concordant dental care. TRIAL REGISTRATION: This project is registered at ClinicalTrials.gov with ID NCT04682730. The trial was first registered on 12/18/2020. https://clinicaltrials.gov/ct2/show/NCT04682730.

Mother's Perceived Social Support and Children's Dental Caries in Northern Appalachia.

Purpose: The purpose of this study was to examine whether perceived social support among mothers with high levels of dental caries was associated with their children experiencing high levels of dental caries. Methods: In West Virginia and Pennsylvania from 2002 to 2009, mothers were interviewed and clinical exams were conducted on their one- to six-year-old children. Two hundred and fifty mother-child dyads were analyzed where the mother had high dental caries. Mothers reported perceived social support across four domains (appraisal, tangible, self-esteem, belonging) from the Interpersonal Support Evaluation List instrument (ISEL), with higher scores representing greater support. The association between each social support domain and the probability of high child dental caries was examined. Results: Twenty-seven percent of children (67 out of 250) had high dental caries, and the odds of children having high caries was lower by seven percent for every one point increase in the ISEL appraisal score (odds ratio equals 0.93; 95 percent confidence interval equals 0.88, 0.99). Tangible, self-esteem, and belonging social support ISEL subscales were not significantly associated with high child dental caries (P>0.05). Conclusions: Among mothers with high dental caries, there was modest evidence that appraisal support-the perceived availability of someone to talk to about problems-was associated with lower odds of their children having high dental caries.

Policies and Procedures That Facilitate Implementation of Evidence-Based Clinical Guidelines in U.S. Dental Schools.

The aim of this study was to determine the degree to which dental schools in the United States have policies and procedures in place that facilitate the implementation of evidence-based clinical guidelines. The authors sent surveys to all 65 U.S. dental schools in 2014; responses were obtained from 38 (58%). The results showed that, of the nine policies and procedures examined, only two were fully implemented by 50% or more of the responding schools: guidelines supported through clinical faculty education or available chairside (50%), and students informed of guidelines in both the classroom and clinic (65.8%). Although 92% of the respondents reported having an electronic health record, 80% of those were not using it to track compliance with guidelines. Five schools reported implementing more policies than the rest of the schools. The study found that the approach to implementing guidelines at most of the responding schools did not follow best practices although five schools had an exemplary set of policies and procedures to support guideline implementation. These results suggest that most dental schools are currently not implementing guidelines effectively and efficiently, but that the goal of schools' having a comprehensive implementation program for clinical guidelines is achievable since some are doing so. Future studies should determine whether interventions to improve implementation in dental schools are needed.

IPS multicentric study: Functional somatic symptoms in depression.

BACKGROUND: As a pilot project, Indian Psychiatric Society conducted the first multicentric study involving diverse settings from teaching institutions in public and private sectors and even privately run psychiatric clinics. AIM OF THE STUDY: To study the typology of functional somatic complaints (FSC) in patients with first episode depression. MATERIALS AND METHODS: A total of 741 patients from 16 centers across the country participated in the study. They were assessed on Bradford Somatic Symptom inventory for FSC, Beck Depression Inventory for severity of depression, and Comprehensive Psychopathological Rating Scale- anxiety index (CPRS-AI) for anxiety symptoms. RESULTS: The mean age of the study sample was 38.23 years (SD-11.52). There was equal gender distribution (male - 49.8% vs. females 50.2%). Majority of the patients were married (74.5%), Hindus (57%), and from nuclear family (68.2%). A little over half of the patients were from urban background (52.9%). The mean duration of illness at the time of assessment was 25.55 months. Most of the patients (77%) had more than 10 FSCs, with 39.7% having more than 20 FSCs as assessed on Bradford Somatic Inventory. The more common FSC as assessed on Bradford Somatic Inventory were lack of energy (weakness) much of the time (76.2%), severe headache (74%) and feeling tired when not working (71%), pain in legs (64%), aware of palpitations (59.5%), head feeling heavy (59.4%), aches and pains all over the body (55.5%), mouth or throat getting dry (55.2%), pain or tension in neck and shoulder (54%), head feeling hot or burning (54%), and darkness or mist in front of the eyes (49.1%). The prevalence and typology of FSCs is to a certain extent influenced by the sociodemographic variables and severity of depression. CONCLUSION: Functional somatic symptoms are highly prevalent in Indian depressed patients and hence deserve more attention while diagnosing depression in Indian setting.
