Orthognathic Surgical Outcomes in Patients With and Without Craniofacial Anomalies.

PURPOSE: The objective of this study is to examine hospitalization outcomes after orthognathic surgery. This study tests the hypothesis that patients with craniofacial anomalies have higher billed hospital charges, longer lengths of stay, and increased odds of development of infectious complications when compared with patients without craniofacial anomalies. MATERIALS AND METHODS: The Nationwide Inpatient Sample for the years 2012 and 2013 was used. All patients who underwent an orthognathic surgical procedure were selected. The primary independent variable of interest was presence of a congenital cleft and/or craniofacial anomaly. The outcome variables were the occurrence of complications, billed hospital charges, and length of stay. Multivariable logistic and linear regression models were used to examine the effect of the presence of craniofacial anomalies on outcomes. RESULTS: During the study period, a total of 16,515 patients underwent an orthognathic surgical procedure in the United States. Of these patients, 2,760 had a cleft and/or craniofacial anomaly. An infectious complication occurred in 7.4% of those with a craniofacial anomaly (compared with 0.6% of those without a craniofacial anomaly). The mean billed hospital charges in those with a craniofacial anomaly was $139,317 (compared with $56,189 in those without a craniofacial anomaly). The mean length of stay in the hospital in patients with a craniofacial anomaly was 8.8 days (compared with 1.8 days in those without a craniofacial anomaly). These differences in outcomes between patients with and patients without craniofacial anomalies were significant after we adjusted for patient- and hospital-level confounders. CONCLUSIONS: Patients with a craniofacial anomaly are at higher risk of development of infectious complications, have higher hospital charges, and stay in the hospital for a longer duration after orthognathic surgery when compared with those without a craniofacial anomaly.

Survival Rates of Stainless Steel Crowns and Multi-Surface Composite Restorations Placed by Dental Students in a Pediatric Clinic.

PURPOSE: This study examined survival rates of multi-surface composite restorations and stainless steel crowns (SSCs) placed by students in a pediatric dental clinic as well as the length of time it takes for restorations to be replaced with stainless steel crowns. STUDY DESIGN: Data from electronic dental records for all children with at least one 2-surface composite restorations or SSCs on a primary first or second molar from January 1, 2007 to September 30, 2015 were analyzed. The primary outcome was the time to a new restoration or SSC on the same tooth, with time to a crown as a secondary outcome. Descriptive statistics were obtained and the cumulative incidence of the event of interest was estimated using 95% confidence intervals and compared between groups using Fine-Gray regression. RESULTS: A total of 6,288 teeth from 2,044 children were analyzed. Three years after the initial procedure, 1.5% of SSCs and 21% of 2 and 3 surface composite restorations failed and needed a replacement (Hazard Ratio [HR]= 14; 95% Confidence interval [CI] 9-22, p<0.001). Also, 6.8% of composite restorations needed replacement with SSCs' (HR=4; 95% CI: 3-7). CONCLUSIONS: The study demonstrates that stainless steel crowns had a higher survival rate than multi-surface composite resins placed by students at a pediatric dental clinic in primary molars of children.

Latino Acculturation and Periodontitis Status Among Mexican-Origin Adults in the United States: NHANES 2009-2012.

This study examined the association between Latino acculturation indicators (language and citizenship/nativity status) and periodontitis using data from the National Health and Nutrition Examination Survey (NHANES) 2009-2012. Descriptive statistics and logistic regression analyses were performed and all analyses were adjusted for the complex survey design. Results showed that 63.2% of participants had periodontitis: 9.4% mild, 37.9% moderate, and 16% severe. Language was significantly associated with periodontitis after adjusting for age, educational level, gender, usual source of care, flossing, smoking, and glycohemoglobin level (P = .02). Dental public and private health efforts should implement culturally tailored oral health promotion education efforts for this population.

Acculturation and Children's dental service utilization in the United States.

OBJECTIVE: The study examined changes in acculturation level, socio-economic status, and their association with preventive dental service use, receipt of restorative, or surgical care, and unmet dental needs. METHODS: Data from the Medical Expenditure Panel Survey (MEPS) for children aged 1 to 17 years from 2007 to 2015 were analysed. Firstly, a cross-sectional structural equation model (SEM) that included both a measurement model and a structural model was fitted simultaneously to obtain predicted latent variables for acculturation, socio-economic status (SES), dental service utilization, and unmet dental needs. Secondly, the change in acculturation, SES, dental service utilization, and unmet dental needs were calculated over two consecutive years within the same child. Finally, the structural model in these changes was fitted, and the indirect and direct pathways between acculturation and SES were tested with dental insurance as a mediator. RESULTS: Data for 33 507 children in both panel years were analysed. An increase in family acculturation resulted in lower utilization of preventive dental service and more unmet dental need, with socio-economic status and dental insurance kept constant between the panel years, and after adjusting for race/ethnicity, gender, and age. In addition, increased acculturation was associated with higher SES, and a higher probability of having obtained dental insurance, both of which resulted in increased preventive dental service utilization and less unmet dental need. The positive direct effect and negative indirect effect of acculturation on unmet dental need cancelled each other out and resulted to almost zero total effect between acculturation and unmet dental need. Similarly, the negative direct effect and positive indirect effect of acculturation on preventive dental service cancelled each other out leading to a small increase in preventive dental service utilization. CONCLUSION: Children of immigrant families are at risk of inadequate access to dental care as their families becomes more acculturated, without increase in SES and access to dental insurance. This study supports policies that promote immigrant family's adequate access to dental insurance and employment to improve their socio-economic status.

American Board of Dental Public Health diplomate survey, 2021: Competency domains and practice.

OBJECTIVE: To describe current Dental Public Health diplomates and list the competency domains that diplomates considered either essential or optional elements of their practice. METHODS: The American Board of Dental Public Health administered an electronic survey to active and life member diplomates during September 2021. The survey included 101 items in three sections: (1) Education and Work Experience; (2) Dental Public Health Tasks; and (3) Demographics. The Dental Public Health Tasks section asked individuals how essential work-related tasks were to their current practice. Descriptive analyses were conducted using SAS. RESULTS: The overall response rate was 82.6% (157 eligible of 190 returned). Most respondents were women, 35 to 54 years of age, and either non-Hispanic white or non-Hispanic Asian. Twice as many had DDS or DMD degrees than BDS degrees. The vast majority completed a Dental Public Health residency and received masters level training from an accredited program. About three-fourths worked in the United States and held a U.S. license. More than 37% reported a second doctoral degree and 70% worked in academia. Responses to questions about tasks closely aligned with working in academia and less so with positions related to advocacy, regulation, and program evaluation. CONCLUSIONS: Current diplomates are concentrated in academia. If this trend continues, it may be necessary to restructure the competencies, so training and skills acquisition remain timely and relevant. The specialty may also need to encourage future generations to consider non-academic positions so Dental Public Health remains an impactful component of the public health care system.

Dental Utilization of Refugee Children in Washington State Varies by Demographic Characteristics.

Purpose: To assess factors associated with the dental utilization of refugee children in Washington state who received oral health care. Methods: This study used Medicaid data of newly arrived children who resettled in 2015. Demographics, refugee population density groups, special care needs, dates of dental encounters, and dental claim variables were analyzed using descriptive statistics, analysis of variance (ANOVA), regression analysis, and the Cox proportional-hazard ratios (P<0.05). Results: Among 1,125 children, 78 percent had at least one dental claim. The majority were under six years (37 percent), male (55 percent), and without disabilities (98 percent). On average children started using dental care within 6.0 months (±4.0 standard deviation) of resettlement (median equals 4.4; interquartile range [IQR] equals 2.6 to 10.3). White children had the greatest mean number of dental claims, whereas Black children had the least (P<0.001). Children from the low-volume refugee population density group were significantly less likely to have a dental claim than children from the medium-volume refugee population density group (P<0.001). Compared to 13- to 21-year-olds, children aged zero to seven years and seven to 13 years had a 46.7 percent (95 percent confidence interval [95% CI] equals 24.9 to 72.3 percent) and 54.8 percent (95% CI equals 30.3 to 83.9 percent) significantly increased likelihood of having their first dental claim (P<0.001). Conclusions: A large percentage (78 percent) of children newly resettled in the state of Washington utilized at least one dental service. Age, race, and refugee population density group were significantly associated with utilization within the initial 12 months after resettlement.

Estimation of oral disease burden from claims and self-reported data.

OBJECTIVE: To compare the use of Medicaid and commercial claims data with self-reported survey data in estimating the prevalence of oral disease burden. METHODS: We analyzed 2018 Medicaid claims from the IBM Watson Medicaid Marketscan database, commercial claims from the IBM Dental Database, and Medical Expenditure Panel Survey (MEPS) data. The estimate of oral disease burden was based on standard metrics using periodontal and caries-related Current Dental Terminology (CDT) procedure codes. A direct comparison between the data sets was also done. RESULTS: Unweighted Medicaid and commercial enrollees were 11.6 and 10.5 million, respectively. The weighted proportion from MEPS for Medicaid and commercial plans ranged from 80 to 208 million people. Estimates of caries-related treatments were calculated from IBM Watson and MEPS data for Medicaid enrollees (13% vs. 12%, respectively) and commercial claims (25% vs. 17%, respectively). Prevalence of periodontal related treatments for those with a dental visit was estimated for IBM Watson and MEPS enrollees for Medicaid (0.7% vs. 0.5%, respectively) and commercial claims (7% vs. 1.6%, respectively). Dental disease estimates were higher in individuals with at least one dental visit across cohorts. Prevalence of disease for those with a dental visit based on specific procedures were higher in commercial plans than in Medicaid. CONCLUSIONS: Claims data has the potential to serve as a proxy measure for the estimate of dental disease burden in a population.

Medications prescribed in emergency departments for nontraumatic dental condition visits in the United States.

BACKGROUND: Prior research has documented factors associated with nontraumatic dental condition (NTDC) visits to emergency departments (EDs), but little is known about the care received by patients in EDs for NTDC visits. OBJECTIVE: We examined national trends in prescription of analgesics and antibiotics in EDs for NTDC visits in the United States. RESEARCH DESIGN: We analyzed data from the National Hospital Ambulatory Medical Care survey from 1997 to 2007. We used a multivariable logistic regression model to examine factors associated with receiving analgesics and antibiotics for NTDC visits in EDs. RESULTS: Overall 74% received at least 1 analgesic, 56% received at least 1 antibiotic, and 13% received no medication at all during NTDC visits to EDs. The prescription of medications at EDs for NTDC visits steadily increased over time for analgesics (odds ratio=1.11/y, P<0.0001) and antibiotics (odds ratio=1.06/y, P<0.0001). In the multivariable analysis, self-pay patients had significantly higher adjusted odds of receiving antibiotics, whereas those with nondental reasons for visits and children (0-4 y) had significantly lower adjusted odds of receiving a prescription for antibiotics in EDs for NTDC visits. Children (0-4 y), adults (53-72 y), and older adults (73 y and older) had lower adjusted odds (P<0.001) of receiving analgesics. CONCLUSIONS: Nationally, analgesic and antibiotic prescriptions for NTDC visits to EDs have increased substantially over time. Self-pay patients had significantly higher odds of being prescribed antibiotics. Adults over 53 years and especially those 73 years and older had significantly lower odds of receiving analgesics in EDs for NTDC visits.

Rural-urban differences in dental service use among children enrolled in a private dental insurance plan in Wisconsin: analysis of administrative data.

BACKGROUND: Studies on rural-urban differences in dental care have primarily focused on differences in utilization rates and preventive dental services. Little is known about rural-urban differences in the use of wider range of dental procedures. This study examined patterns of preventive, restorative, endodontic, and extraction procedures provided to children enrolled in Delta Dental of Wisconsin (DDWI). METHODS: We analyzed DDWI enrollment and claims data for children aged 0-18 years from 2002 to 2008. We modified and used a rural and urban classification based on ZIP codes developed by the Wisconsin Area Health Education Center (AHEC). We categorized the ZIP codes into 6 AHEC categories (3 rural and 3 urban). Descriptive and multivariable analysis using generalized linear mixed models (GLMM) were used to examine the patterns of dental procedures provided to children. Tukey-Kramer adjustment was used to control for multiple comparisons. RESULTS: Approximately, 50%, 67% and 68% of enrollees in inner-city Milwaukee, Rural 1 (less than 2500 people), and suburban-Milwaukee had at least one annual dental visit, respectively. Children in inner city-Milwaukee had the lowest utilization rates for all procedures examined, except for endodontic procedures. Compared to children from inner-city Milwaukee, children in other locations had significantly more preventive procedures. Children in Rural 1-ZIP codes had more restorative, endodontic and extraction procedures, compared to children from all other regions. CONCLUSIONS: We found significant geographic variation in dental procedures received by children enrolled in DDWI.

Hall Technique: Knowledge and Attitudes of Pediatric Dentists in the United States.

Purpose: To assess pediatric dentists' knowledge, attitudes, and factors associated with the use of the Hall technique (HT) in the United States.
Methods: An electronic questionnaire with a cover letter and consent form was sent to 6,277 active members of the American Academy of Pediatric Dentistry (AAPD) between April 15 and June 1, 2019. Descriptive and multivariate analyses were calculated.
Results: The response rate was 9.4 percent; 52 percent were males, 76 percent were white non-Hispanic, and 83 percent were in private practice. Ninety-seven percent were familiar with HT, and 39 percent had used it. Factors significantly associated with the use of HT were female dentists (P =0.01), patients with Medicaid insurance (P <0.001), rural locations (P =0.02), academic and community/public health clinics (P =0.004). Compared with AAPD members in the Western region, pediatric dentists in the North-Central region were more likely to use HT (odds ratio [OR] =2.50, 1.22 to 5.13, P =0.01) but pediatric dental residents in the North-Central region were less likely to use it (OR= 0.39,0.18 to 0.84, P =0.02).
Conclusion: Use of HT was considered a viable alternative in the management of dental caries. Despite the limitations of the technique, pediatric dentists' practice location and place of residency were significantly associated with its use.

Dental access and expenditures for adults with intellectual and other disabilities.

OBJECTIVES: Individuals with disabilities experience greater barriers accessing health care services and have poorer oral health outcomes than those without disabilities. The aims of this study were to examine dental access, utilization, expenditures, and sources of payment between adults with intellectual disabilities (ID), other types of disabilities, and without disabilities. METHODS: Secondary analyses of data from the 2017 Medical Expenditure Panel Survey (MEPS) allowed examination of dental access (being able to get dental care and receiving necessary dental care without delay), dental utilization (having a dental visit in the past year), total dental expenditures, and associated sources of payment between three groups of adults based on disability status using descriptive, bivariate, and multivariable statistics. RESULTS: Adults with ID have 2.70 (95% CI: 2.03, 3.61) times the odds of being unable to get dental care and 2.88 (95% CI: 2.11, 3.94) times the odds of having to delay necessary dental care compared with adults without disabilities. No significant differences were observed in dental utilization or mean total dental expenditure between the three groups after adjusting for demographic and socioeconomic variables. Among adults who incurred a dental expenditure, adults with ID had a greater share of dental care paid for by Medicaid, and adults without disabilities had a greater share of dental care paid for by private insurance. CONCLUSIONS: Despite similar mean total dental expenditures, reduced dental access reported by adults with ID suggests that this population experiences significantly greater challenges obtaining dental care. Adults with ID rely more heavily on Medicaid to finance dental care.

National Trends and Characteristics in Emergency Department Visits for Nontraumatic Dental Conditions Among Pediatric Patients.

Purpose: The purpose of this study was to examine trends and characteristics of pediatric nontraumatic dental condition (NTDC) visits to emergency departments (EDs) in the United States from 2010 to 2017. Methods: The 2010 to 2017 Nationwide Emergency Department Sample (NEDS) was analyzed for NTDC visits to EDs for children (zero to 20 years old). NTDC visits were identified based on ICD-9 and ICD-10 codes. Patient characteristics analyzed included age, sex, primary payor, county population, day of discharge, and household income. Descriptive statistics and a logistic regression analysis for 2016 and 2017 were completed. Results: Pediatric NTDC visits to EDs decreased from 103.1 to 89.3 per 10,000 ED visits between 2010 and 2017. Pediatric NTDC ED visits by Medicaid enrollees increased from 51 percent to 65.3 percent from 2010 to 2017. This was followed by a corresponding decrease among uninsured pediatric patients with NTDC visits to EDs. The odds of NTDC visits to EDs were higher among Medicaid enrollees, 15- to 20-year-olds, and the uninsured but were lower among those in wealthier zip codes. Conclusions: Emergency department visits for nontraumatic dental condition visits by pediatric patients decreased over time following the implementation of the Affordable Care Act. Despite this decrease, low socioeconomic status children continue to utilize emergency departments for dental conditions at higher rates than their peers.

Test of an organizational change model to reduce no-shows in dental care settings.

OBJECTIVES: To test the feasibility and preliminary effectiveness of the NIATx model for organizational change to reduce appointment no-shows in dental care settings. METHODS: The NIATx Dental Pilot Study used a clustered prepost interventional design and a mixed-methods approach. Five independent dental clinics serving Medicaid enrollees were recruited. Quantitative data on the impact of the NIATx model were complemented by qualitative assessment information collected from dental staff. The NIATx model was applied through a multisite learning collaborative that engaged participating organizations in adopting targeted no-show best practices. The primary outcome measure was no-show data collected at the preintervention phase (5 months), intervention phase (7 months), and postintervention phase (3 months). RESULTS: Female patients were in the majority (median 54.5 percent). Mean age ranged from 8 to 50 (median 35.2) years. The median percentage for Hispanics was 11.0 percent, and the proportion of uninsured patients was 25 percent. Preintervention no-show rates ranged from 14 percent (clinic B) to 38 percent (clinic E). All clinics had lower no-show rates during the postintervention period, with decreases ranging from 1 percent (clinic B) to 13 percent (clinic E). Overall, the no-show rates decreased in the study. CONCLUSIONS: The study demonstrated the feasibility of applying the NIATx model to reduce no-show rates, with some difficulty observed with sustainability across dental practices during the postintervention period.

Geographic variations in dental sealant utilization by Medicaid enrollees.

OBJECTIVE: To investigate geographical variations and their relationship to race/ethnicity in dental sealant utilization for first molars among Wisconsin Medicaid enrollees from 2010 to 2013. METHODS: Wisconsin Medicaid dental claims for sealants in children aged 6-16 years were analyzed. County-level population density, urban influence code, presence of dental health professional shortage areas, and population-per-dentist ratio were considered as geographic predictors. Descriptive statistics and mixed effects Poisson regression models were used to examine the effect of county level covariates on the number of dental sealants received per person-year (PY) of eligibility adjusting for patient-level characteristics. Over-dispersion was modeled by a random residual effect, and all models adjusted for single-year age and gender interaction and race/ethnicity main effect. RESULTS: Medicaid claims for sealants on first permanent molars for 2010-2013 totaled 288,019 over 1,130,000 PY. The age- and gender-standardized rate of first molar sealant applications per 100 PY were 27.9, 25.7, and 16.6 for White, Hispanic, and Black children, respectively. County-specific rates ranged from a low of 8.9 per 100 PY to a high of 62.6 per 100 PY. In the multivariate analysis after adjusting for geography, compared to Whites, Hispanics had highest rates (rate ratio (RR) = 1.33, 95% CI = 1.30-1.37) of dental sealant utilization followed by Blacks (RR = 1.25, 95% CI = 1.21-1.29). Population density was the only significant geographic predictor (RR = 0.56 per 10-fold increase, 95% CI = 0.45-0.69). CONCLUSIONS: Substantial geographic variability in the utilization of sealants for first molars was identified. Lower population density was the main geographical predictor of high sealant utilization.

Dental service utilization and immigrant family structure.

OBJECTIVES: To determine the patterns and time trends of dental services received and access to dental care among immigrant and US-born children living in the United States. METHODS: We analyzed the nationally representative Medical Expenditure Survey data for 2007-2015. Survey weighted mean and frequency were calculated for all the years and for each year for the complete cohort and for the four subgroups of children categorized based on the child's and parents' birthplace (United States or Foreign). These groups were compared to detect differences in dental service received. RESULTS: Overall 34,482 children aged <18 years were included in the analysis representing the weighted sample size of 564,255,643. Utilization of preventive dental services increased from 37.2 percent in 2007 to 44.4 percent in 2015 overall (P < 0.0001), with similar trend seen within all subgroups. Immigrant children compared to US-born children had higher numbers of surgical and restorative procedures (17 versus 16 per 100-person years, P = 0.03), fewer had at least one preventive dental visit in a year (32.8 percent versus 43.0 percent, P < 0.0001) and were less likely be unable to access dental care (3.0 percent versus 1.7 percent, P = 0.005). Fewer children had delayed access to dental care in recent years (2.0 percent in 2007 to 1.5 percent in 2015) and the decline was consistent in all the subgroups. CONCLUSION: Stratification into the different subgroups allowed for improved understanding of dental procedure utilization and dental services utilization in all subgroups increased over time. Immigrant children had lower utilization of preventive procedures and higher utilization of surgical and restorative procedures.

Provision of fluoride varnish treatment by medical and dental care providers: variation by race/ethnicity and levels of urban influence.

OBJECTIVE: In 2004, Wisconsin Medicaid policy changed to allow medical care providers to be reimbursed for fluoride varnish treatment (FVT) to children's teeth to improve access and utilization. To date, no study has been published on whether geographic and racial/ethnic variation in the provision of FVT in response to this policy change exists. This study's objective is to examine the association of rates of FVT for children enrolled in Wisconsin Medicaid with race/ethnicity, urban influence codes (UIC), and dental health professional shortage area (DHPSA) designation based on county of residence. METHODS: A retrospective, pre-post design was used based on FVT claims for children in the Wisconsin Medicaid program from 2002 to 2006. Poisson regression models were used to evaluate the association of rates of FVT claims with race/ ethnicity, UIC, and DHPSA designation. RESULTS: The rate of FVT claims varied by resident county-type according to UIC and DHPSA designation, age, and race/ethnicity. Post-policy, the largest increases were observed for Native Americans residing in non-DHPSA counties, enrollees living in rural counties, and for Hispanics living in partial and entire DHPSA counties. African-Americans residing in partial DHPSA and metropolitan counties displayed the lowest rates of FVT claims. CONCLUSIONS: Overall access and utilization of FVT increased, but substantial racial/ ethnic and geographic variation in the provision of FVT for children enrolled in Wisconsin Medicaid was observed. Future policies should incorporate measures that will specifically address the racial and geographic variations identified in this study.

Dental sealants and restorative treatment for first molars among Medicaid enrollees.

OBJECTIVES: To assess the association between dental sealant placement and subsequent restorative treatment of permanent first molars over time. METHODS: We analysed Wisconsin Medicaid claims data from 2001 to 2009 for children aged 6-16 years. Children entered the study cohort at age 6 and were censored if Medicaid eligibility was lost for >31 days. A fixed effects analysis via a Cox proportional hazards model, stratified by individual, was used to estimate the time-averaged and time-dependent effects of sealant placement on dental treatment defined as any restorative, endodontic or surgical procedure. RESULTS: A total of 185,262 children with permanent first molars who turned 6 years enrolled in Medicaid were examined. Sealant placement was higher for teeth #16 and 26 (5.42 and 5.46 per 100 person-years (100PY), versus 5.29 and 5.31/100PY for #36 and 46, respectively. The average rate for restorative treatments had the opposite pattern, with lower rate for teeth #16 and 26 (1.78 and 1.72/100PY) versus teeth #36 and 46 (2.14 and 2.12/100PY), respectively. In the fixed effects regression model, the hazard of dental treatment was substantially lower after sealant placement on a tooth, with time-averaged hazard ratio HR = 0.23 (95% CI 0.21-0.25, P < .001) versus before sealant. The largest effect was in the first year after sealant placement (HR = 0.13, 95% CI: 0.11-0.14), which decreased over time (HR = 0.50, 0.59 and 0.74 in years 2, 3 and 4, respectively), and was not statistically significant in later years. CONCLUSIONS: This study demonstrates that permanent first molar sealant placement delayed subsequent dental treatments in children enrolled in Medicaid.

Factors associated with receipt of preventive dental treatment procedures among adult patients at a dental training school in Wisconsin, 2001-2002.

BACKGROUND: Gender differences in oral health-related quality of life and the fear of dental pain in seeking and receiving preventive dental care have been recognized and documented. Preventive dental treatment procedures (PDTPs) are commonly accepted as the primary approach to prevent dental disease. OBJECTIVE: We examined whether the likelihood of receiving PDTPs differed by gender in adult patients receiving dental care at a dental training institution in Milwaukee, Wisconsin. METHODS: Data from the Marquette University School of Dentistry electronic patient management database for 2001 through 2002 were analyzed. Descriptive, bivariate, and multivariable analyses were performed. The preventive procedures used in the study were those coded in accordance with the American Dental Association's classification system: D1110 (adult prophylaxis: professional cleaning and polishing of the teeth), D1204 (adult topical application of fluoride), D1205 (adult topical application of fluoride plus prophylaxis), and D1330 (oral hygiene instruction). RESULTS: Of the 1563 consecutive patient records (888 women, 675 men) reviewed for the years 2001-2002, 794 individuals (51%), aged 18 to 60 years, were identified as having received PDTPs. At the bivariate level, a significant gender difference in the receipt of PDTPs was identified (423 women [48%] vs 371 men [55%]; P = 0.004). In the multivariable analyses, age, race/ethnicity, marital status, poverty level, and health insurance type (public, private, none) were significantly associated with the receipt of PDTPs (all, P < 0.05), but gender was not. CONCLUSIONS: Gender differences in receiving PDTPs were not found in this dental school patient population. Receipt of PDTPs was associated with other demographic factors such as age, race/ethnicity, marital status, income level, and health insurance.
