Background Outcome studies of nonsurgical root canal treatment (NSRCT) in permanent teeth of children are scarce. This study investigated survival and assessed the variables associated with failure of endodontically treated teeth (ETT) in 6- to 18-year-olds. Methods Records of subjects who received NSRCT at age 6–18 years at Boston University between 2007 and 2015 were assessed for the occurrence of untoward events. Kaplan–Meier survival curves were used to investigate the survival of ETT in the total sample. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) were estimated. Results The analysis included 341 patients (424 ETT). Kaplan–Meier survival curves differed according to age at treatment (log-rank P = 0.026), with survival being the lowest among the youngest age group. The estimated 5-year survival probability was 80% for 15- to 18-year-olds, 64.8% for 12- to 14-year-olds and 46.4% for 6- to 11-year-olds. Compared to age at treatment of 15–18 years, age at treatment of 6–11 years (aHR: 2.19, 95% CI 1.02–4.67) and 12–14 years (aHR: 2.02, 95% CI 1.15–3.55) was associated with an increased risk of ETT failure. In the total study sample, the estimated cumulative survival probability was 93.3% at 12 months, 88.0% at 24 months, 76.2% at 36 months, 71.0% at 48 months, and 69.1% at 60 months. Conclusions In children, ETT are more likely to survive when NSRCTs are performed at an older age.

Objective The aim of this study was to develop the Teen Oral Health-Related Quality of Life instrument (TOQOL) and demonstrate its validity and reliability in a diverse sample of 13–18-year-old adolescents. Methods A total of 363 adolescents aged 13–18 years participated in this cross sectional study. Oral screening examinations were conducted to collect oral health status data. Adolescents completed the TOQOL and a generic measure of health-related quality of life, the PedsQL. The psychometric properties of the TOQOL were evaluated in terms of face, content, convergent, concurrent and discriminant validity in addition to internal reliability. Results The 16-item TOQOL covers five domains: Physical functioning, Role functioning, Social functioning, Oral problems, and Emotional functioning. The total scale and subscales showed satisfactory reliability with Cronbach alpha ranging from 0.75 to 0.92. TOQOL scores showed significant associations with perceived oral health status and the PedsQL (convergent validity) and discriminated well between adolescents with caries and adolescents who were caries free (discriminate validity). Conclusion The TOQOL is a valid and reliable oral health-related quality of life measurement that can be recommended for self-report in adolescents aged 13-18 years.

There is a paucity of data on the validity of self-report of periodontal disease in African Americans. The Black Women's Health Study (BWHS), a United States national cohort study of 59,000 black women followed via mailed questionnaires since 1995, offered the opportunity to clinically validate self-reported periodontitis among a sample of participants.Oral health questionnaires were sent to study participants residing in Massachusetts. Respondents living in the Boston metro area were invited for clinical examination. Self-reports were compared with clinical data obtained from the 77 women (mean age: 59 years) who were examined. The authors examined the predictive ability of individual and combined questionnaire items with respect to clinical periodontal disease severity. Validation parameters were calculated for each question, and receiver operating characteristic statistics were generated to compare questionnaire items.Periodontitis prevalence in the validation sample was 24% for severe periodontitis and 61% for moderate disease. Performance of individual questionnaire items with respect to predicting periodontitis was better for severe compared with moderate disease. Combinations of questionnaire items improved the predictive ability with respect to severe disease beyond that of individual questionnaire items.Prevalence of severe periodontitis was similar to other age-comparable populations, without regard for race or sex, whereas prevalence of total periodontitis (moderate and severe) among women of similar age and/or race was much higher. Predictive ability of questionnaire items assessed in the BWHS was similar to that in other studies.

Objectives This study compared scores and psychometric properties from self-identified Hispanic parents who completed Pediatric Oral Health-related Quality of life (POQL) parent report-on-child questionnaires in Spanish or English. The study hypothesized that there were no differences in psychometric properties or POQL scores by parent reading language preference, controlling for dental needs, child's place of birth, age, insurance and use of care. Methods POQL scores were computed, and the internal consistency, feasibility, factor structure and construct validity of the Spanish language version assessed. Results Hispanic parents (N = 387) of 8-14 year old children (mean age 10.2) completed the survey; 237 in Spanish and 150 in English. Internal consistency scores were higher (Cronbach α range = .86-.93) among Hispanic parents who completed the questionnaire in Spanish than in English (.66-.86). POQL scores from parents who completed questionnaires in Spanish were higher (worse) overall (6.03 vs. 3.82, P = 0.022), as were physical (11.61 vs. 6.54, P = 0.001) and role functioning domains (1.87 vs. 0.82, P = 0.029). Items for crying, pain, and eating were higher (P

Objective Identify structure and process variables that significantly contributed to dentist productivity across VA Dental Service clinics using multiple VA national datasets from fiscal year 2010. Methods A retrospective, longitudinal analysis with the primary outcome of care provided, as measured by relative value units per clinically mapped full-time employee equivalent dentist, per year. Predictor variables included physical plant variables, staffing variables, complexity of the patient population, workplace climate, and environment of care. Predictor variables were initially assessed in a bivariate analysis with the primary outcome and those significant at P

Our objective was to examine the Teen Oral Health-related Quality of Life (TOQOL) questionnaire for use in adults receiving orthodontic treatment and assess validity and reliability by age group.Teenagers from 10 to 18 years and adults 18 and over completed surveys at the orthodontic clinic at Boston University. The survey consisted of sociodemographic information, dental behavior questions, and the TOQOL instrument. Malocclusion severity was assessed using the Index of Orthodontic Treatment Need.Overall, 161 teens and 146 adults participated. The mean ages were 13 years for the teens and 32 years for the adults. Subjects were represented by both sexes and diverse racial and ethnic backgrounds. In general, scores overall and by domains were higher for adults than for teens, signifying a greater effect of the malocclusion on the quality of life. Mean TOQOL scores as well as emotional and social domain scores (P 0.001) were worse (17.6) in adults than in teens (11.9; P 0.01). Construct validity was supported by strong a association of TOQOL scores with self-reported oral health. The Cronbach alpha was higher in adults overall and for all domains (0.75 in adults compared with 0.68 in teens).Adults who come for orthodontic treatment appear to be more affected by their malocclusion than are teens. The total TOQOL score and the emotional and social domains were significantly higher for adults. The total TOQOL score and the emotional and social domains were significantly higher (worse) for adults than teens. This project suggested that TOQOL may be a useful way to measure the impact of malocclusion on the quality of life in both adults and teens.

Objective: To assess the sensitivity of a newly developed brief measure of oral health-related quality of life (OQOL). Methods: Self-assessed oral health and OQOL were measured in three groups of patients who had presented for either prophylaxis (n = 32), endodontic care (n = 15), or for a denture (n = 16) in a dental school setting before and after treatment. Main outcome measures included the single-item self-report of oral health (OH-1) and the 6- and 12-item versions of a new OQOL instrument. General linear modeling was used to compute means of self-reported oral health by treatment group. Results: Of the 63 patients who completed the baseline questionnaire, 44 (70 percent) returned questionnaires after treatment. The sample averaged 43 ± 15 years, 48 percent male and 55 percent with some college education. Ethnic representation included 35 percent White, 33 percent Black, and 32 percent other – mostly Latino. The mean self-reported number of teeth was 20.6. In terms of sensitivity, significant differences were observed between the treatment groups on the items assessing being upset (P

Objective The aim of this study was to assess homeless veterans' perception of their oral health and the impact that oral disease and treatment have on self-assessed quality of life. Methods Outcomes included measures of general and oral-specific quality of life and functional status. Single-item self-report of oral health and the General Oral Health Assessment Index were assessed at baseline and after treatment. Results One hundred and twelve veterans completed the baseline questionnaire, and 48 completed the follow-up. Veterans who were eligible for ongoing dental care had improved General Oral Health Assessment scores, while patients who received only emergency dental care saw a decreased score (2.46 versus -2.12). General Oral Health Assessment improvement was significantly related to fewer teeth at baseline (18 versus 23), a lower baseline General Oral Health Assessment (23.6 versus 28.1), having a denture visit (22 versus 35 percent), and improvement in self-reported oral health (25 versus 42 percent). Conclusion There was significant improvement in homeless veterans'perceived oral health after receiving dental care.

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 ≥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.

Objectives: We are conducting a clinical trial of the efficacy of periodontal therapy in the improvement of glycaemic control in veterans with poorly controlled diabetes. This report describes study design, recruitment and randomization and compares baseline characteristics of the sample frame with those randomized into study groups. Methods: Veterans with poorly controlled diabetes were randomized in two groups: immediate periodontal therapy (“early treatment”) or usual care followed by periodontal therapy (“deferred treatment”). Half of each group continued care for 12 months; the other half returned to their usual care. We studied baseline patient characteristics, self-reported health measures, and clinical examination data. We examined means for continuous variables, frequencies for categorical variables and compared groups using t-tests and χ2 tests (α=0.05 for both). Results: The 193 randomized participants were younger (58 years) and had slightly higher HbA1c (10.2%) than the 2534 non-randomized participants (64 years, HbA1c =9.8%). The deferred treatment group was more likely than the early treatment group to have a history of stroke, transient ischaemic attacks, and less likely to be current or former smokers. Conclusions: The mechanism for randomization was largely successful in this study.

Objectives: Report results of a randomized-clinical trial of the efficacy of periodontal care in the improvement of glycemic control in 165 veterans with poorly controlled diabetes over 4 months. Methods: Outcomes were change in Haemoglobin A1c (HbAlc) in the Early Treatment versus untreated (Usual Care) groups and percent of participants with decreases in HbAlc. Analyses included simple/multiple variable linear/logistic regressions, adjusted for baseline HbAlc, age, and duration of diabetes. Results: Unadjusted analyses showed no differences between groups. After adjustment for baseline HbAlc, age, and diabetes duration, the mean absolute HbAlc change in the Early Treatment group was - 0.65% versus - 0.51% in the Usual Care group (p = 0.47). Adjusted odds for improvement by 0.5% in the Early Treatment group was 1.67 (95% confidence interval: 0.84, 3.34, p = 0.14). Usual Care subjects were twice as likely to increase insulin from baseline to 4 months (20% versus 11%, p = 0.12) and less likely to decrease insulin (1% versus 6%, p = 0.21) than Early Treatment subjects. Among insulin users at baseline, more increased insulin in the Usual Care group (40% versus 21%, p = 0.06). Conclusions: No significant benefit was found for periodontal therapy after 4 months in this study; trends in some results were in favour of periodontal treatment.

Objectives To examine the effect of overall dietary quality on number of teeth with new or recurrent root caries events during follow-up (root caries increment). Design Prospective study with dental examinations approximately every 3 years over 20 years. Setting Veterans Affairs Dental Longitudinal Study in greater Boston, Massachusetts, area. Participants Men aged 47 to 90 (N = 533). Measurements A single calibrated examiner assessed root caries and restorations, calculus, probing pocket depth, and attachment loss on each tooth at each examination. The adjusted root caries increment (root-ADJCI) was computed from new and recurrent root caries events on teeth with recession of 2 mm or more. Dietary information was obtained from food frequency questionnaires. An adherence score was computed by comparing consumption frequency of 10 food groups (fruits, vegetables, total dairy, low-fat dairy, meat, total grains, high-fiber grains, legumes, fats, sweets) from the Dietary Approaches to Stop Hypertension (DASH) diet guidelines. Mean root-ADJCIs were compared according to DASH adherence score quartile using generalized linear negative binomial regression models, controlling for age, number of teeth at risk of root caries, time at risk of root caries, calculus, presence of removable denture, history of dental prophylaxis, body mass index, and smoking status. Results Men with DASH adherence scores in the highest quartile had a 30% lower mean root-ADJCI (1.86 teeth) than those in the lowest quartile (2.68 teeth) (P = .03). Root-ADJCI was lower with greater adherence to recommendations for vegetables and total grains and greater with greater sugar-sweetened carbonated beverage consumption. Root caries incidence rate did not vary significantly between quartiles. Conclusion A higher-quality diet may reduce root caries risk in older men.

Objectives: To quantify the adverse effects of the number of xerostomic medications on dental caries, oral mucosa, andperiodontal disease. Design: Secondary analysis of across-sectional study of the Veterans Dental Study. Setting: Four New England area VA outpatient clinics. Subjects: The sample consists of 345 male veterans participating in The Veteran's Dental Study who also had pharmacy records. Main outcome measures: Oral health data included total surfaces of coronal caries, a modification of the root caries index, mean oral mucosa scores, and Community Periodontal Index of Treatment Need (CPITN). Oral health parameters were measured and recorded in clinical dental examinations. Exposures: Intake of xerostomic medications 14-385 days prior to the dental examination. Statistical Analyses: The relationships between exposure and outcome were analyzed via linear and logistic regression methods adjusting for possible confounding factors such as disease burden index, alcohol consumption, dental care, and smoking status. Results: Veterans who were taking at least one xerostomic medication were almost three times more likely to have mean mucosa scores in the worst 25 percentile than veterans taking no xerostomic medications, OR= 2.63 (confidence interval [CI] 1.34,5.16, p=0.03) after adjusting for age, number of teeth, disease burden index, income, smoking and alcohol use. Participants who were taking at least one xerostomic medication experienced higher but non-significant increases in coronal (OR =1.21; CI. 0.66, 2.25) and root caries (OR =1.10 CI. 0.54, 2.24) measured by numbers of total decayed surfaces. Conclusion: There were significant deleterious effects of xerostomic medications on oral mucosa. However, xerostomic medications do not appear to increase coronal caries, or periodontal index measured by CPITN among ambulatory, community dwelling participants who were able to perform routine preventive oral care.

We used data from Boston Medical Center, Massachusetts, to determine whether dental-related emergency department (ED) visits and costs increased when Medicaid coverage for adult dental care was reduced in July 2010. In this retrospective study of existing data, we examined the safety-net hospital’s dental-related ED visits and costs for 3 years before and 2 years after Massachusetts Health Care Reform. Dental-related ED visits increased 2% the first and 14% the second year after Medicaid cuts. Percentage increases were highest among older adults, minorities, and persons receiving charity care, Medicaid, and Medicare.

To develop a brief measure of oral health-related quality of life (OHQL) in children and demonstrate its reliability and validity in a diverse population.We administered the initial 20-item Pediatric Oral Health-Related Quality of Life (POQL) to children (Child Self-Report) and parents (Parent Report on Child) from diverse populations in both school-based and clinic-based settings. Clinical oral health status was measured on a subset of children. We used factor analysis to determine the underlying scales and then reduced the measure to 10 items based on several considerations. Multitrait analysis on the resulting 10-item POQL was used to reaffirm the discrimination of scales and assess the measure's internal consistency and interscale correlations. We established discriminant and convergent validity with clinical status, perceived oral health and responses on the PedsQL, and determined sensitivity to change with children undergoing ECC surgical repair.Factor analysis returned a four-scale solution for the initial items--Physical Functioning, Role Functioning, Social Functioning, and Emotional Functioning. The reduced items represented the same four scales--two each on Physical and Role and three each on Social and Emotional. Good reliability and validity were shown for the POQL as a whole and for each of the scales.The POQL is a valid and reliable measure of OHQL for use in preschool and school-aged children, with high utility for both clinical assessments and large-scale population studies.

To examine the association of xerogenic medications with the oral mucosa inflammation score (OMS) in US male veterans.The relationship of having the worst 25th percentile in OMS and intake of xerogenic medications with different pharmacologic indications was analyzed by logistic regression, controlling for age in 3 categories (or =44, 45-64,or =65), smoking, disease burden index, alcohol abuse, and the duration of medication, in 290 subjects participating in the Veterans Dental Study.When polypharmacy and denture-wearing status in addition to the aforementioned covariates were controlled, the odds ratios for cardiovascular disease medications and sympathetic agonists were 2.82 (95% confidence interval [CI] 1.35-5.91, P.006), and 2.96 (CI 1.21-7.26, P.02), respectively, and those for psychotropics and antihistamines were 2.12 (CI 0.94-4.80, P.06) and 2.09 (CI 0.80-5.48, P0.14), respectively.Xerogenic medication may be associated with oral mucosal pathology.
