RESUMEN

INTRODUCTION: Obesity is associated with greater utilization of medical resources, but it is unclear if a similar relationship exists for dental care. OBJECTIVES: This retrospective cohort study compared periodontal disease treatment among obese, overweight, and normal-weight patients attending an urban US dental school clinic. METHODS: Periodontal, demographic, and medical history data for 3,443 adult patients examined between July 1, 2010, and July 31, 2019, were extracted from electronic health records. Body mass index (BMI) was computed from self-reported height and weight and categorized as obese (≥30 kg/m2), overweight (25-29.9 kg/m2), or normal (18-24.9 kg/m2). Periodontal disease was categorized using clinical probing measures. Procedure codes defined treatment type (surgical, nonsurgical, local chemotherapeutics, or none). Logistic regression models controlling for initial periodontal disease severity, age, gender, tobacco use, history of diabetes, dental insurance type, and follow-up (log of days) estimated odds ratios (ORs) and 95% confidence intervals (CIs) of any treatment among obese and overweight relative to normal-weight patients. The association between BMI and a periodontal treatment intensity score, based on treatment type, number of teeth treated, and number of visits, was evaluated with multivariable negative binomial regression. RESULTS: Mean age at baseline was 44 ± 15 y, and severe periodontal disease was present in 32% of obese, 31% of overweight, and 21% of normal-weight patients. Average follow-up was 3.9 ± 1.6 y. Obese and overweight patients were more likely to have nonsurgical scaling and root planing or surgical procedures than normal-weight patients. Adjusted odds of any treatment were higher among obese (OR = 1.34; 95% CI, 1.14-1.72) and overweight (OR = 1.18; 95% CI, 0.97-1.42) relative to normal weight. Obese and overweight patients had 40% and 24% higher treatment intensity scores, respectively, than normal-weight patients. CONCLUSION: These results indicate obese and overweight individuals require more intensive periodontal treatment compared to normal-weight individuals, independent of initial disease severity. KNOWLEDGE OF TRANSFER STATEMENT: The results of this study can be used by dental providers and policymakers to better understand patient characteristics that influence the variability in frequency and length of periodontal treatment. Knowledge of a patient's body mass index may be useful in identifying patients who possibly will have a poorer periodontal prognosis.

RESUMEN

The prophylactic removal of asymptomatic third molars is a common but controversial procedure often rationalized as necessary to prevent future disease on adjacent teeth. Our objective in this retrospective cohort study of adult men was to examine whether second-molar loss differed by baseline status of the adjacent third molar, taking into account the individual's overall state of oral hygiene, caries, and periodontitis. We analyzed data from participants of the VA Dental Longitudinal Study who had at least 1 second molar present at baseline and 2 or more triennial dental examinations between 1969 and 2007. We classified second molars by third-molar status in the same quadrant: unerupted, erupted, or absent. Tooth loss and alveolar bone loss were confirmed radiographically. Caries and restorations, calculus, and probing depth were assessed on each tooth. We estimated the hazards of second-molar loss with proportional hazards regression models for correlated data, controlling for age, smoking, education, absence of the first molar, and whole-mouth indices of calculus, caries, and periodontitis. The analysis included 966 men and 3024 second molar/first molar pairs. Follow-up was 22 ± 11 y (median 24, range 3-38 y). At baseline, 163 third molars were unerupted, 990 were erupted, and 1871 were absent. The prevalence of periodontitis on the second molars did not differ by third-molar status. The prevalence of distal caries was highest on the second molars adjacent to the erupted third molars and lowest on the second molars adjacent to the unerupted third molars. Relative to the absent third molars, adjusted hazards of loss of second molars were not significantly increased for those adjacent to erupted (hazard ratio [HR] = 0.96, 95% confidence interval [CI] = 0.79-1.16) or unerupted (HR = 1.25, 95% CI = 0.91-1.73) third molars. We found similar results when using alveolar bone loss as the periodontitis indicator. Our findings suggest that retained third molars are not associated with an increased risk of second-molar loss in adult men.

RESUMEN

Early childhood caries (ECC) is a largely preventable condition that occurs when children develop caries in their primary teeth before the age of six. National trends of ECC indicate that prevalence is decreasing, but disparities between various sociodemographic groups may be increasing, despite intervention efforts. Dynamic mechanisms in caries development are hypothesized to be responsible for the observed population distributions of disease. Agent-based models (ABMs) have been utilized to explore similar hypotheses in many areas of health research. Therefore, we developed an ABM of ECC development mechanisms and examined population outcomes of hypothetical preventive intervention scenarios. We found that risk-based targeting had minimal impact on population averages or disparities and was largely due to the strength of the dynamic mechanisms among those considered to be at high caries risk. Universally increasing intervention access reduced population caries prevalence, but increased disparities between different groups of caries risk profiles. We show that population distributions of ECC can emerge as a result of dynamic mechanisms that have been shown to drive disease development. Understanding the effectiveness of a proposed intervention in relation to the hypothesized mechanism(s) that contributes to the outcome of interest is critical to future efforts to address population disparities in ECC.

RESUMEN

The American Association for Dental Research (AADR) is committed to providing a collegial, safe, and welcoming environment for all. As part of this effort, we assessed perceptions and experiences related to sexual, gender-based, and non-gender-based harassment among registrants at AADR annual meetings from 2015 to 2018 (n = 10,495); examined demographic factors associated with reported experiences; and identified facilitators and potential solutions concerning these types of harassment. Registrants were emailed an invitation to an anonymous online survey. Demographics were assessed categorically, and response distributions to close-ended survey items were evaluated by these variables. Bivariate analyses of participant demographics were conducted with 8 types of perceived harassment. To determine the demographic distribution of reporters, along with bivariate associations among them, restricted analyses were performed among individuals reporting any type of harassment. Qualitative data analysts conducted content analysis of the open-ended responses to questions asking participants to reflect on the topic. Peer debriefing was used to refine the coding schema. A total of 824 responses were received, of which 172 individuals reported experiencing ≥1 of the 8 types of harassment surveyed. Among those, reports of condescending remarks occurred most frequently (70%). Reported harassment of a more sexual nature was less common by comparison. Reporters of harassment were more likely to be women, members of the AADR/CADR (Canadian Association for Dental Research) divisions, and/or frequent meeting attendees. A total of 229 respondents answered at least 1 of the open-ended questions. While the majority of survey respondents reported no personal experience with harassment at AADR meetings, the fact that 1 in 5 did should be cause for concern. In 2018, AADR introduced a "Professional Conduct at Meetings Policy" delineating unacceptable behaviors, including intimidating or harassing speech and actions. Results of this survey form an important baseline from which its impact may be monitored to ensure that future AADR meetings are respectful, supportive, and safe environments for all.

RESUMEN

INTRODUCTION: Caries experience among preschool-age children has remained relatively unchanged for the past 2 decades, despite recently documented decreases in untreated decay. OBJECTIVES: In a community-based cluster-randomized controlled trial, a motivational interviewing (MI) intervention administered to primary caregivers was hypothesized to reduce caries increment over 2 y as compared with controls, among children aged 0 to 5 y at baseline living in public housing. METHODS: Public housing residents, who served as interventionists, were trained in MI with a focus on early childhood caries prevention. All 26 eligible public housing developments were randomized to either control (quarterly clinical examinations, fluoride varnish applications, toothbrush/toothpaste, and educational brochures) or intervention (same procedures as control plus MI counseling). Quarterly MI sessions were delivered in English or Spanish over 2 y, audio recorded, and assessed for treatment fidelity. The primary outcome was the increment in dmfs (decayed, missing, and filled tooth surfaces) as assessed by clinical examination at baseline, 12 mo, and 24 mo. Secondary outcomes included caregiver oral health knowledge and child oral health behaviors (child toothbrushing and sugar-sweetened beverage intake). Baseline characteristics were compared between groups and adjusted for housing-site clusters. Longitudinal outcomes were analyzed with mixed models. RESULTS: A total of 1,065 children (49% female, 55% non-White, 61% Hispanic, 89% below poverty level, n = 686 control) and their caregivers were enrolled. During 2 y of follow-up, the mean dmfs increment increased in both groups; however, there were no statistically significant group differences at 24 mo or group × time interactions. The mean increase in intervention caregivers' knowledge was significantly greater than that of control, F(2, 1,593) = 3.48, P = 0.0310, but there were no significant intervention effects on caregiver-reported child sugar-sweetened beverage intake or child toothbrushing. CONCLUSION: MI counseling plus intensive caries prevention activities resulted in knowledge increases but did not improve oral health behaviors or caries increment (ClinicalTrials.gov NCT01205971). KNOWLEDGE TRANSFER STATEMENT: When viewed in light of the findings from the companion Pine Ridge study and other recent MI studies, the results of this study suggest that when the complex disease of early childhood caries is addressed in high-risk populations, MI is not effective, and alternative approaches are warranted.

RESUMEN

The relationship between bone mineral density and tooth loss in men is unclear. The aim of this retrospective cohort study was to determine if relative metacarpal bone area (MCA) predicts tooth loss in a cohort of 273 male participants in the Dental Longitudinal Study and Normative Aging Study of the Department of Veterans Affairs. Outer and inner cortical bone widths of the middle metacarpal of the nondominant hand were measured on anteroposterior hand radiographs approximately 11 y apart. Baseline MCA was computed and categorized into quartiles. The men were followed from 1971 to 2015. Incident tooth loss during 2 intervals was examined: concurrent with the MCA measurements and long term over the total follow-up (17 ± 7 y). Radiographic alveolar bone loss (ABL) was measured on periapical radiographs as a percentage of the distance from the cementoenamel junction to root apex, and the number of teeth with ABL >40% was computed. Negative binomial generalized linear regression models estimated the mean number of teeth with ABL >40% and the number lost (concurrent and total), controlling for age, smoking, number of teeth at baseline, percentage teeth with ≥1 decayed/filled surface, and years of follow-up. At baseline, MCA was inversely related to number of teeth with >40% ABL. Men in the lowest MCA quartile (Q1) lost the most teeth, both concurrent with MCA measurements and long term, but the association differed by caries level (≤55% or >55% decayed/filled teeth). At the low caries level, the numbers lost in Q1 were 29% greater than in the highest MCA quartile (Q4). At the high caries level, the numbers lost in Q1 were more than twice those in Q4. Associations were attenuated when further controlled for number of teeth with ABL>40%. These findings suggest that systemic bone status plays a role in tooth loss and that the association may be mediated by alveolar bone loss. Knowledge Transfer Statement: Low relative metacarpal bone area was related to loss of alveolar bone and incident tooth loss in men. This information extends previous research, primarily studies of women, showing that osteoporosis adversely affects oral health. Knowledge of a patient's systemic bone status may be important for managing his or her periodontal disease. Tooth loss in the absence of periodontal inflammation may signify systemic bone loss. Interprofessional communication is central to maintaining optimal oral and bone health.

RESUMEN

Metabolic syndrome, a cluster of 3 or more risk factors for cardiovascular disease, is associated with periodontal disease, but few studies have been prospective in design. This study's aim was to determine whether metabolic syndrome predicts tooth loss and worsening of periodontal disease in a cohort of 760 men in the Department of Veterans Affairs Dental Longitudinal Study and Normative Aging Study who were followed up to 33 y from 1981 to 2013. Systolic and diastolic blood pressures were measured with a standard mercury sphygmomanometer. Waist circumference was measured in units of 0.1 cm following a normal expiration. Fasting blood samples were measured in duplicate for glucose, triglyceride, and high-density lipoprotein. Calibrated periodontists served as dental examiners. Periodontal outcome events on each tooth were defined as progression to predefined threshold levels of probing pocket depth (≥5 mm), clinical attachment loss (≥5 mm), mobility (≥0.5 mm), and alveolar bone loss (≥40% of the distance from the cementoenamel junction to the root apex, on radiographs). Hazards ratios (95% confidence intervals) of tooth loss or a periodontitis event were estimated from tooth-level extended Cox proportional hazards regression models that accounted for clustering of teeth within individuals and used time-dependent status of metabolic syndrome. Covariates included age, education, smoking status, plaque level, and initial level of the appropriate periodontal disease measure. Metabolic syndrome as defined by the International Diabetes Federation increased the hazards of tooth loss (1.39; 1.08 to 1.79), pocket depth ≥5 mm (1.37; 1.14 to 1.65), clinical attachment loss ≥5 mm (1.19; 1.00 to 1.41), alveolar bone loss ≥40% (1.25; 1.00 to 1.56), and tooth mobility ≥0.5 mm (1.43; 1.07 to 1.89). The number of positive metabolic syndrome conditions was also associated with each of these outcomes. These findings suggest that the metabolic disturbances that comprise the metabolic syndrome may play a role in the development or worsening of periodontitis.

RESUMEN

Prophylactic extraction of unerupted asymptomatic third molars is the most common oral surgery procedure in the United States. However, limited evidence exists to justify its costs and associated morbidity. We analyzed data collected over 25 years from 416 adult men enrolled in the Veterans Affairs Dental Longitudinal Study to evaluate the association of retained asymptomatic third molars with risk of adjacent second molar pathology (caries and/or periodontitis), based on third molar status (i.e., absent, erupted, or unerupted). Unerupted molars were further categorized as either "soft tissue" or "bony" impacted. We found that the lowest prevalence and incidence of second molar pathology occurred when the adjacent third molar was absent. The presence of a third molar that was soft tissue impacted increased the risk of incident second molar pathology 4.88-fold (95% confidence interval: 2.62, 9.08). Having an erupted or "bony" impacted third molar increased the risk of incident second molar pathology by 1.74 (95% confidence interval: 1.34, 2.25) and 2.16 (95% confidence interval: 1.56, 2.99), respectively. The retention of third molars is associated with increased risk of second molar pathology in middle-aged and older adult men.

RESUMEN

Vitamin D, an anti-inflammatory mediator, has potential benefits for physical and oral health. Although it is produced endogenously, some individuals have a greater need for dietary and supplemental sources. This repeated-measures cross-sectional study assessed associations between total vitamin D intake and periodontal health in older men. Participants were 562 members of the Department of Veterans Affairs Dental Longitudinal Study, mean age 62.9 years, who were examined 1 to 4 times between 1986 and 1998. A calibrated examiner measured probing pocket depth (PPD) and attachment loss (AL) on each tooth. Alveolar bone loss (ABL) was determined from radiographs. Severe periodontal disease was defined as PPD ≥ 5 mm on ≥ 1 tooth and AL ≥ 6 mm at ≥ 2 sites (not on same tooth), and moderate-to-severe alveolar bone loss as ABL ≥ 40% at ≥ 3 sites. Generalized estimating equations were used to compute the odds ratios (OR) and 95% confidence intervals (95% CI) of having periodontal disease by level of vitamin D intake. Total vitamin D intake ≥ 800 IU was associated with lower odds of severe periodontal disease (OR = 0.67, 95% CI = 0.55-0.81) and moderate-to-severe ABL (OR = 0.54, 95% CI = 0.30-0.96) relative to intake < 400 IU/day. Vitamin D intake may protect against periodontal disease progression.

RESUMEN

Most studies linking obesity and periodontal disease have been cross-sectional in design. We examined whether gains in body weight, waist circumference, and arm fat area are associated with periodontitis progression in 893 non-diabetic men followed for up to four decades in the prospective VA Dental Longitudinal Study. Probing pocket depth (PPD) was measured by calibrated examiners. Repeated-measures generalized linear models estimated the mean cumulative numbers of teeth with PPD events (PPD > 3 mm) at each dental examination and the slopes associated with increasing numbers of affected teeth over time. Means were adjusted for baseline PPD, education, and cigarette pack-years, and time-dependent values of age, mean plaque score, cigarette packs/day, brushing, and flossing. Men who were overweight at baseline and gained weight most rapidly (> 0.19 kg/yr or ~15 lb during follow-up) had significantly more PPD events than men in the lowest tertile of weight gain (≤ -0.05 kg/yr). Overweight men whose waist circumference increased > 0.14-0.39 or > 0.39 cm/yr experienced more PPD events than men in the lowest tertile (≤ 0.14 cm/yr). Increase in arm fat area was associated with disease progression in normal-weight men. These results suggest that tracking adiposity changes with easily obtained anthropometric measures may help predict risk of periodontitis progression.

RESUMEN

PURPOSE: This study's purpose was to compare changes in parent-reported pediatric oral health-related quality of life between children with early childhood caries (ECC) and children who were caries-free; the ECC children received surgical dental intervention between baseline and follow-up. METHODS: A newly developed self-report instrument, the POQL, was administered to 501 parents of 2- to 8-year-old children (caries-free=315; ECC=186) in hospital dental clinics in Columbus, Ohio, and Washington, D.C. RESULTS: At baseline, ECC children were more likely to have fair or poor oral health and were rated as having more pain and trouble with physical, mental, and social functioning due to their teeth or mouth vs caries-free children (P<.001). At 6 and 12 months following dental treatment for ECC, there were significant improvements in parental ratings of their children's oral health status and a significant reduction in problems reported with physical, mental, and social functioning (all P<.001). CONCLUSIONS: Compared with caries-free children, early childhood caries children were more likely to have worse questionnaire response scores and to experience greater negative impacts on physical, mental, and social functioning. Dental interventions in ECC children had a significant positive impact on parental ratings of their overall oral health and physical, mental, and social functioning.

RESUMEN

Early childhood caries (ECC) is a preventable form of dental caries that affects very young children, particularly among low-income families and certain racial/ethnic minorities. The current study examined the relationship of dietary quality, as measured by the Healthy Eating Index (HEI), to the prevalence of ECC in 2- to 5-year-old children. Data from the Third National Health and Nutrition Examination Survey (NHANES III) were used for the study. We used logistic regression to compute adjusted odds ratios (OR) for ECC and 95% confidence intervals (CI). Children with the best dietary practices (uppermost tertile of the HEI) were 44% less likely to exhibit severe ECC compared with children with the worst dietary practices (lowest tertile of the HEI). A healthy eating pattern geared for promotion of optimal child development and prevention of chronic disease in later life may also reduce the risk of early childhood caries, particularly severe early childhood caries.

RESUMEN

Data on the dose-dependent effects of smoking and smoking cessation on tooth loss are scarce. We hypothesized that smoking has both dose- and time-dependent effects on tooth loss incidence. We used longitudinal data on tobacco use and incident tooth loss in 43,112 male health professionals, between 1986 and 2002. In multivariate Cox models, current smokers of 5 to 14 and 45+ cigarettes daily had a two-fold (HR, 1.94; 95% CI, 1.72, 2.18) and three-fold (HR, 3.05; 95% CI, 2.38, 3.90) higher risk of tooth loss, respectively, compared with never-smokers. Risk decreased with increasing time since cessation, but remained elevated by 20% (95% CI, 16%, 25%) for men who had quit 10+ years before. Current pipe/cigar smokers had a 20% (95% CI, 1.11, 1.30) increased risk of tooth loss compared with never- and former smokers of pipes/cigars.
