RESUMO
To investigate the association between parenting style and child's dental caries. Parents presenting with their children to the Department of Pediatric Dentistry at Tufts University School of Dental Medicine for an initial exam or re-care appointment completed a demographic survey and the parenting styles and dimensions questionnaire. Recruitment of subjects started in May 2019 and ended in February of 2020. Child's decayed, missing, and filled teeth (dmft) index, diet score, sex, and age were recorded, as were parent's race, education level, and form of payment. Adjustment for confounders was done using multivariable negative binomial regression. The sample size was 210 parent/child dyads. In the multivariable analysis, parenting style and child's dmft were not significantly associated (p > 0.05). Parents with an education level less than high school (p = 0.02) and at the high school graduate level (p = 0.008) were significantly associated with children who had higher dmft, compared to parents with a college degree or higher. Children with excellent diet scores had significantly lower dmft than children with a diet score in the "needs improvement" category (p = 0.003). There was no significant evidence that parenting style is associated with child's dental caries. Parent's education level and child's diet score were significantly associated with child's dmft, less than high school (p = 0.02) and at the level of high school graduate (p = 0.008). Pediatric dental professionals should be aware of these risk indicators.

OBJECTIVE: To investigate the prevalence of self-reported depressive symptoms among predoctoral dental students in the United States and examine potential correlates. METHODS: A survey was emailed to all 66 dental schools in the United States, inviting them to distribute it to their predoctoral students. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Data collection occurred from February to April 2020. Multivariable ordinal logistic regression was used to assess associations between demographic variables and depressive symptom severity category, adjusting for potential confounding. RESULTS: Of an estimated 25,000 predoctoral dental students at the 66 schools, 631 students from 21 schools completed the survey. A total of 24.1% were categorized as having minimal or no depressive symptoms, 33.6% as having mild depressive symptoms, and 42.3% as having moderate, moderately severe, or severe depressive symptoms. Gender (p = 0.015) and race/ethnicity (p = 0.002) were significant predictors of severity, adjusting for other variables. Students identifying as female had higher odds of self-reporting greater depressive severity symptoms compared with students identifying as male. Students identifying as African American/Black (non-Hispanic) and Asian/Pacific Islander had higher odds of self-reporting greater depressive severity symptoms compared with students identifying as White. CONCLUSION: There is evidence of a high prevalence of depressive symptoms among predoctoral dental students in the United States. Demographic variables may be risk indicators within this population. Approaches to reduce depressive symptoms among US predoctoral dental students are needed.

INTRODUCTION: Lowe syndrome (LS) is an uncommon condition that affects the brain, kidneys, nervous system, and eyes, predominantly in males. The aim of this study was to examine dental conditions, dental treatments, and access and/or barriers to care for those with LS compared to healthy individuals. METHODS: Surveys assessing dental conditions, dental treatments, and access and/or barriers to care were administered to families in the Lowe Syndrome Association and families with healthy children who had dental appointments at the Tufts University School of Dental Medicine (TUSDM) pediatric dental clinic. One parent or a guardian of pediatric patients with LS or not at TUSDM was asked to complete an online survey. RESULTS: One hundred and eight surveys were obtained (n:58 from the LS group and n:50 from the healthy group). The LS group was significantly more likely (p < .05) to report "crooked/misaligned teeth," "difficult time chewing," "bad breath," and "mouth cysts" and was significantly less likely to report 6-month examination, "cleaning," and "filling." The LS group reported significantly greater difficulty locating a dentist. CONCLUSION: The findings of this study indicate that individuals with LS are more vulnerable to developing severe dental conditions and experiencing difficulties in accessing dental care than healthy individuals. Additionally, those who present with this syndrome may be less likely to receive specific necessary dental treatments. As a result, it is essential to offer appropriate dental care and support to individuals with LS to guarantee they achieve optimal oral health.

OBJECTIVE: This cross-sectional study assessed the implementation of documenting a baseline caries risk assessment (CRA) of patients seen by predoctoral dental students and its association with the presence of caries risk management (CRM) treatment. METHODS: A convenience sample of 10,000 electronic axiUm patient records at Tufts University School of Dental Medicine was retrospectively assessed for the presence or absence of a completed CRA and CRM after IRB approval following predetermined inclusion and exclusion criteria. The CRM variables (nutrition counseling, sealant, fluoride) were identified by procedure codes that were completed by the student. Associations were assessed via the chi-square test, Kruskal-Wallis test (with Dunn's test and the Bonferroni correction used in post-hoc tests) and Mann-Whitney U test. RESULTS: Most patients (70.5%) had a CRA completed. However, only 24.9% (out of the 7045 patients with a completed CRA) received CRM, while 22.9% of the 2,955 patients without a CRA received CRM. The difference between the groups with and without a completed CRA in terms of the percentage receiving CRM was not clinically significant. Significant associations were found between a completed CRA and in-house fluoride treatment (p = .034) and between a completed CRA and sealant treatment (p = .001). Patients with higher baseline CRA levels (i.e., greater risk) were more likely to have CRM (16.9% of the 785 patients at low risk, 21.1% of the 1282 patients at moderate risk, 26.3% of the 4347 patients at high risk, and 32.6% of the 631 patients at extreme risk). The association between these two variables was significant (p < .001). CONCLUSION: There is evidence that students were mostly compliant with completing a CRA for most patients; however, there is a deficiency in implementation of CRM approach to help support dental caries management, and there is still much room for improvement.

OBJECTIVE: The purpose of this research was to investigate correlates of burnout among predoctoral dental students in the United States. METHODS: All 66 dental schools in the US were invited to distribute a survey on topics such as demographics, year of dental school, and burnout to their predoctoral students. Burnout was assessed via the Maslach Burnout Inventory-Human Services Survey, which has three subscales: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA). Multivariable modeling was conducted via generalized linear models using the lognormal distribution to adjust for confounding. RESULTS: The survey was completed by 631 students from 21 dental schools. When adjusting for confounding, students identifying as African American/Black (Non-Hispanic) (regression coefficient [95% CI]: -0.13 (-0.23, -0.02]) or Asian/Pacific Islander (-0.08 [-0.13, -0.02]) reported feeling significantly lower PA than students identifying as white. Students identifying as female reported feeling significantly greater EE (0.18 [0.10, 0.26]), but significantly less DP (-0.26 [-0.44, -0.09]), than students identifying as male. Third- (0.28 [0.07, 0.50]) and fourth-year (0.40 [0.17, 0.63]) students reported significantly higher EE than first-year students, while second- (0.40 [0.18, 0.62]), third- (1.06 [0.59, 1.53]), and fourth-year (1.31 [0.82, 1.81]) students reported significantly higher DP than first-year students. CONCLUSIONS: Risk indicators for burnout among US predoctoral dental students may depend on the dimension of burnout. Identifying those at higher risk of burnout can facilitate the implementation of counseling and other effective intervention strategies. Such identification can also provide insight into how the dental school environment might be contributing to the marginalization of those at higher risk.

OBJECTIVE: The aim of this retrospective study was to evaluate a Dental Sleep Medicine Mini-Residency (DSMMR) continuing education (CE) program using the Kirkpatrick model. METHODS: After receiving ethical approval, data from participants in the 2019-2020 DSMMR CE course were included for the Kirkpatrick evaluation. The analysis was stratified and all the Kirkpatrick levels were integrated: level 1 (satisfaction) was assessed via Likert scale and open-ended questions; level 2 (learning) was evaluated using pretest and posttest knowledge data following Module 1 (M1) and an assessment of multiple-choice questions (MCQs) developed by participants; level 3 (behavior) was evaluated using Likert scale questions; and level 4 (results) was assessed via the percentage of participants who passed the American Board of Dental Sleep Medicine (ABDSM) examination on their first attempt. RESULTS: A total of 90 participants were included in the study. At least 83.1% of participants agreed/strongly agreed with positively worded statements about satisfaction. Knowledge scores significantly increased from pre-M1 to post-M1 (p < 0.001); however, only 15.2% of MCQs were evaluated as well-formulated. At least 88.6% of participants agreed/strongly agreed with positively worded statements about transfer of knowledge/skills to their practice. 91.1% passed the ABDSM examination on their first attempt. CONCLUSION: The evaluation of the 2019-2020 DSMMR using the Kirkpatrick model suggests its overall positive impact as a training program. The Kirkpatrick model provided information that can be used to improve the quality of a program. Future studies should assess other dental CE programs using the Kirkpatrick model or another evaluation model.

INTRODUCTION: Cone-beam computed tomography (CBCT) scans are routinely used by endodontic residents and faculty at Tufts University School of Dental Medicine for diagnostic purposes but are not routinely read for pathologic findings by a radiologist. In a 2017 study by Oser et al (part 1), endodontic residents and a radiologist interpreted CBCT scans taken for endodontic diagnostic purposes, and their findings were compared. The results demonstrated that a radiologist is significantly more likely to report incidental findings in small field of view (FOV) scans. A limitation of this study was that the radiologist used a checklist of common findings to review the scans. The purpose of this study was to examine whether the use of a checklist would improve the sensitivity of the endodontic residents' reporting of incidental findings in small FOV CBCT scans. METHODS: The 203 small FOV CBCT scans used in part 1 were obtained and reviewed by endodontic residents in a systematic fashion. Radiographic findings were reported using a blank checklist. The results were compared with those previously reported. RESULTS: The radiologist reported abnormalities in 176 of the 203 subjects (87%), and the residents reported abnormalities in 184 of the 203 subjects (91%). There was an increase in false positive findings when the residents were using a checklist. CONCLUSIONS: The use of a checklist improved the sensitivity but decreased the specificity of the reporting of incidental findings in small FOV CBCT scans by endodontic residents.

High levels of inflammatory cytokines in serum have been reported in patients with severe SARS-CoV-2 infection. There is growing interest in recognizing the role of inflammatory biomarkers in saliva in diagnosing systemic diseases. This study assumed that estimating biomarkers in saliva samples from patients infected with SARS-CoV-2 would distinguish between mild and severe cases. Saliva was collected from 142 controls and 158 SARS-CoV-2 patients (mild 72 and severe 86) to measure interleukin-6 (IL-6), C-reactive protein (CRP), and C-X-C motif chemokine ligand-10 (CXCL-10). IL-6 and CXCL-10 were significantly increased in patients with mild and severe SARS-CoV-2 infections. CRP was significantly increased only in severe SARS-CoV-2 cases. All biomarkers were significantly higher in severe cases than in mild cases (p < 0.001). Among patients with SARS-CoV-2 infection, men showed significantly higher CRP and CXCL-10 levels than females (p < 0.01 and 0.05, respectively). In addition, elderly patients (40-80 years) had significantly higher IL-6, CRP, and CXCL-10 (p < 0.001). Patients with diabetes and hypertension showed elevated IL-6, CRP, and CXCL-10 (p < 0.001). There was a significant positive correlation between IL-6, CRP, CXCL-10, and between age, IL-6, CRP, and CXCL-10. Saliva may have a future value in measuring the inflammatory biomarkers associated with the severity of SARS-CoV2 infection and therapeutic monitoring.
RESUMO
Despite an explosion of mobile app offerings for management of pain and anxiety, the evidence for effectiveness is scarce. Placebo-controlled trials are the most desirable but designing inactive placebo apps can be challenging. For a prospective randomized clinical trial with 72 patients in a craniofacial pain center, we created an app with self-hypnotic relaxation (SHR) for use with iOS and Android systems. A placebo background audio (BA) app was built with the same look and functionality. Both iOS and Android SHR apps alone and in comparison to the BA group significantly reduced pain and anxiety during the waiting-room time. The Android BA app significantly reduced anxiety but not pain. The iOS BA app affected neither pain nor anxiety, functioning as an ideal placebo. Usage analysis revealed that different default approaches of the iOS and Android devices accounted for the difference in results.

INTRODUCTION: The spread of coronavirus disease 2019 (COVID-19) in the spring of 2020 resulted in the temporary suspension of elective dental procedures and clinical dental education in academic institutions. This study describes the use of the Tufts University School of Dental Medicine emergency dental clinic during the peak surge in COVID-19 cases in Massachusetts, highlighting the number of endodontic emergencies. METHODS: Aggregate data from clinical encounters and call records to an emergency triage phone line from March 30 through May 8, 2020, were used to describe the characteristics of dental emergencies, clinical encounters, and procedures performed. RESULTS: A total of 466 patient interactions occurred during this period, resulting in 199 patients advised by phone and 267 clinical encounters. The most common dental emergencies were severe dental pain from pulpal inflammation (27.7% of clinical encounters) followed by a surgical postoperative visit (13.1%). The most frequent procedures were extractions (13.9% of clinical encounters) and surgical follow-up (13.5%); 50.2% of the clinical encounters were categorized as aerosol generating, and 86.1% of encounters would have required treatment in a hospital emergency department if dental care was not available. There were no known transmissions of severe acute respiratory syndrome coronavirus-2 among clinic providers, patients, or staff during this period. CONCLUSIONS: These results highlight the importance of endodontic diagnosis and treatment in the provision of emergency dental care during a pandemic and demonstrate that dental treatment can be provided in a manner that minimizes the risk of viral transmission, maintaining continuity of care for a large patient population.

INTRODUCTION: Radiography has played a fundamental role in the advancement of nonsurgical root canal therapy (NSRCT), allowing for more accurate diagnosis and treatment. Typically, providers choose to perform NSRCT using periapical (PA) radiographs alone or, often in more difficult cases, in conjunction with cone-beam computed tomographic (CBCT) imaging. This study aimed to evaluate the outcomes of NSRCT based on imaging modality selection for the initial treatment of maxillary first molars. METHODS: A retrospective chart review was conducted using 1385 cases of NSRCT on maxillary first molars. Charts were reviewed for patient demographics and treatment outcomes. Based on the imaging modality used, patients were stratified into 2 groups (PA radiographs alone or PA radiographs + CBCT imaging). Those who required additional treatment(s) after the completion of NSRCT were classified as having "posttreatment disease." Statistical analysis was performed to assess the differences between groups. RESULTS: After the completion of primary endodontic therapy, 5.8% (n = 81) of the entire sample had posttreatment disease. CBCT imaging was used in 13.4% (n = 185) of NSRCTs. Although not significant, cases that were difficult enough to require the use of CBCT imaging had a higher rate of posttreatment disease compared to those that could be completed with PA radiographs alone (8.6% vs 5.4%, P > .05). Results from a multivariable logistic regression model showed that the need for CBCT imaging had a nonsignificant positive association with posttreatment disease (P > .05). CONCLUSIONS: The decision to use CBCT imaging appears to serve as a proxy for case complexity and the associated increase in risk of posttreatment disease. This is important to keep in mind when assessing treatment prognosis.

The use of surveys is popular in dental education research. However, designing and conducting a survey can have many pitfalls. This article aims to prepare a new researcher or one with little experience to undertake survey research. It covers points such as survey design (including question construction), pilot testing for validity and reliability, sampling strategy, methods to increase response rates, logistical considerations, and items to include when writing the manuscript. Careful consideration of a survey from beginning to end can help one design and conduct a successful study that meets its research aims and adds valuable evidence to the literature.

INTRODUCTION: Screening of patients for opioid risk has been recommended prior to opioid prescribing. Opioids are prescribed frequently in the emergency department (ED) setting, but screening tools are often of significant length and therefore limited in their utility. We describe and evaluate three approaches to shortening a screening tool: creation of a short form; curtailment; and stochastic curtailment. METHODS: To demonstrate the various shortening techniques, this retrospective study used data from two studies of ED patients for whom the provider was considering providing an opioid prescription and who completed the Screener and Opioid Assessment for Patients with Pain-Revised, a 24-item assessment. High-risk criteria from patients' prescription drug monitoring program data were used as an endpoint. Using real-data simulation, we determined the sensitivity, specificity, and test length of each shortening technique. RESULTS: We included data from 188 ED patients. The original screener had a test length of 24 questions, a sensitivity of 44% and a specificity of 76%. The 12-question short form had a sensitivity of 41% and specificity of 75%. Curtailment and stochastic curtailment reduced the question length (mean test length ranging from 8.1-19.7 questions) with no reduction in sensitivity or specificity. CONCLUSION: In an ED population completing computer-based screening, the techniques of curtailment and stochastic curtailment markedly reduced the screening tool's length but had no effect on test characteristics. These techniques can be applied to improve efficiency of screening patients in the busy ED environment without sacrificing sensitivity or specificity.

OBJECTIVES: To investigate the association between upper lip thickness and the amount of upper lip repositioning upon retraction of maxillary incisors. SETTING AND SAMPLE POPULATION: Pre- and post-treatment lateral cephalograms of 101 patients were reviewed. All subjects were treated with fixed orthodontic appliances including extraction of two maxillary premolars. Only subjects without change in lip thickness between pre- and post-treatment cephalograms were included. MATERIAL AND METHODS: Digital software measurements for lip thickness, pre- and post-treatment upper lip position were performed. Appropriate regression models were developed to explore the correlation between maxillary incisor retraction and lip retraction when controlling for lip thickness and other confounding factors. The level of statistical significance was set at 0.05 for all analyses. RESULTS: A significant correlation was found between change in maxillary incisor position following premolars extraction and change in upper lip position (r = 0.95, P < 0.001). The average ratio between maxillary incisor retraction and upper lip repositioning was 1.43:1. Upper lip thickness was not significantly associated with this ratio (r = 0.003, P > 0.05). CONCLUSION: Although there is a highly significant correlation between maxillary incisor retraction and upper lip repositioning, lip thickness is not significantly associated with the amount of repositioning.

The countdown method is a well-known approach to reducing the average length of screening instruments that are presented by computer. In the countdown method, testing is terminated once the result of the screener ("positive" or "negative") has been unambiguously determined from prior answers. Previous research has examined whether presenting dichotomously scored items in order from "least to most frequently endorsed" or "most to least frequently endorsed" is more efficient when the countdown method is used. The current study describes the Mean Score procedure, an extension of the above item ordering procedures to polytomously scored items, and evaluates its efficiency relative to the distribution of other possible item orderings in 2 real-data simulations. Both simulations involve item responses to the Posttraumatic Stress Disorder (PTSD) Checklist for DSM-5 (PCL-5). In the first simulation, items were scored polytomously, and a single cutoff point was used to determine the screening result. In the second simulation, items were converted to dichotomous scores, as well as categorized into 4 clusters; a positive result for the entire assessment was obtained if and only if a positive result was obtained for each cluster. The latter simulation also investigated the effect of reordering the clusters themselves on the efficiency of the countdown method. Results indicated that the Mean Score procedure does not necessarily produce the optimal ordering, but tends to assemble an efficient item ordering relative to the distribution of possible orderings. In the second simulation, reordering the clusters themselves affected efficiency. Future research directions are suggested. (PsycINFO Database Record

BACKGROUND: The Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) is a 24-item assessment designed to assist in the prediction of aberrant drug-related behavior (ADB) among patients with chronic pain. Recent work has created shorter versions of the SOAPP-R, including a static 12-item short form and two computer-based methods (curtailment and stochastic curtailment) that monitor assessments in progress. The purpose of this study was to cross-validate these shorter versions in two new populations. METHODS: This retrospective study used data from patients recruited from a hospital-based pain center (n=84) and pain patients followed and treated at primary care centers (n=110). Subjects had been administered the SOAPP-R and assessed for ADB. In real-data simulation, the sensitivity, specificity, and area under the curve (AUC) of each form were calculated, as was the mean test length using curtailment and stochastic curtailment. RESULTS: Curtailment reduced the number of items administered by 30% to 34% while maintaining sensitivity and specificity identical to those of the full-length SOAPP-R. Stochastic curtailment reduced the number of items administered by 45% to 63% while maintaining sensitivity and specificity within 0.03 of those of the full-length SOAPP-R. The AUC of the 12-item form was equal to that of the 24-item form in both populations. CONCLUSIONS: Curtailment, stochastic curtailment, and the 12-item short form have potential to enhance the efficiency of the SOAPP-R.

INTRODUCTION: The use of cone-beam computed tomography (CBCT) in endodontics has increased in recent years. In clinical application of small field of view (FOV) CBCTs, these scans are not reviewed routinely by a radiologist. Studies of large FOV CBCT scans show the prevalence of incidental findings to be greater than 90%. The purpose of this study was to evaluate the prevalence of missed findings by endodontic residents as compared with a radiologist on small FOV CBCT scans. METHODS: Two hundred three small FOV CBCTs obtained for endodontic purposes were analyzed by an endodontic resident and a medical radiologist. The reported findings of each practitioner were compared to evaluate for missed incidental findings by the endodontic resident. RESULTS: The radiologist reported abnormalities in 176 of the 203 subjects (87%), with a total of 310 abnormalities reported. The endodontic resident reported abnormalities in 102 of the 203 subjects (50%), with a total of 126 abnormalities reported. The percentage of scans with any abnormality reported by the radiologist was significantly greater than the endodontic resident (P < .001). There was no significant difference between jaw locations in percentage of missed findings for the 3 most common types of finding-rarefying osteitis, sinusitis/mucosal lining thickening, and excess restorative material in the periapical area. Rarefying osteitis was missed significantly less than the other 2 types of findings (P < .001). CONCLUSIONS: A radiologist is significantly more likely to identify incidental findings in small FOV CBCT scans than an endodontic resident. Scan location had no significant association with the rate of missed findings.

AIM: To test whether the use of collagen matrix seal (CMS) results in similar hard and soft tissue remodelling to that with collagen sponge (CS) used as barriers 4 months following alveolar ridge preservation (ARP), in combination with freeze-dried bone allograft (FDBA). MATERIALS AND METHODS: Twenty-eight patients were randomly assigned to the two groups. Clinical and radiographic measurements were recorded with the same stent at baseline and 4 months for standardization. The flapless technique following a traumatic extraction was used for the two types of barriers. RESULTS: All patients completed the study, 14 in the CMS group and 14 in the CS group. Reduction in coronal ridge width (1.21 mm-14.91% CMS and 1.47 mm-20.40% CS) and vertical buccal bone resorption (0.30 mm CMS and 0.79 mm CS) were not significantly different. A slight increase in buccal gingival thickness at the coronal part was observed in both groups (0.9 mm CMS and 0.5 mm CS). CONCLUSIONS: Collagen matrix seal and CS, when combined with FDBA, significantly minimized ridge resorption in all dimensions and maintained buccal soft tissue thickness in sockets with a buccal plate loss of <2 mm in comparison to previously reported findings recorded after tooth extraction without ARP.
