Clinical and patient-level predictors of procedure and tooth survival after direct pulp capping.

BACKGROUND: Historical reports of unpredictable outcomes associated with vital pulpal therapies, particularly direct pulp capping (DPC), have contributed to clinicians' skepticism of the procedure. Contemporary reports highlight more predictable outcomes of vital pulpal therapies, inclusive of DPC. There is a dearth of reported patient-centered outcomes of these procedures. METHODS: Insurance claims were used in an observational, retrospective cohort study to evaluate outcomes of DPC performed on permanent teeth. Statistical analyses included Kaplan-Meier survival estimates and Cox proportional hazards regression. Log-rank tests were used to evaluate unadjusted differences in survival. Cox proportional hazard regression was used to evaluate the adjusted hazard of adverse event occurrence. RESULTS: The analytic cohort included 4,136 teeth from 3,716 patients. DPC procedures were identified in public-payer (85.5%) and private-payer (13.4%) insurance claims databases. After DPC, procedure survival rate was 83% and tooth survival rate was 93% during a mean follow-up time of 52 months. Molar tooth type, same-day permanent restoration placement, and amalgam restoration type were significant positive predictors of procedure (DPC) survival. Age was not a statistically significant predictor of procedure survival after controlling for tooth type, gender, time to restoration, and restoration type. Nonmolar tooth type and younger age were significant positive predictors of tooth survival after DPC. Failures were most likely to occur within the first year. CONCLUSIONS: DPC has favorable patient-centered outcomes and contributes to long-term tooth survival. PRACTICAL IMPLICATIONS: The favorable patient-centered outcomes of DPC bolster calls to consider cost-effectiveness and access to care for endodontic procedures.

Access to Care Considerations for the Endodontic Treatment of Immature Permanent Teeth: A National Survey of Pediatric Dentists and Endodontists.

INTRODUCTION: This study aimed to investigate access to care and financial considerations associated with the endodontic treatment of immature permanent teeth. METHODS: Surveys were distributed to endodontists (n = 2,457) and pediatric dentists (n = 3,974) in the United States. Data were analyzed using X2 analysis and logistic regression. The level of significance was set to 0.05. RESULTS: The response rate was 13% (n = 840). Respondent specialist groups were similar by age and years since specialty residency completion, but significantly different with regard to primary practice setting (eg private practice, Federally Qualified Health Center, hospital), (P = .001). The majority (91%) of respondents reported participation with dental insurance. Pediatric dentists (69%) were significantly more likely than endodontists (17%) to participate with public-payer dental insurance (P < .001). The majority of respondents (82%) indicated that patients reported economic factors (time or money) as a barrier to accessing endodontic treatment. Pediatric dentists were significantly more likely to consider economic factors when planning for treatment (P < .001). Pediatric dentists were more likely than endodontists to have the opinion that endodontic procedures for treatment of necrotic immature permanent teeth should cost less than root canal therapy (apexification, P < .001; regenerative endodontic procedures, P = .002). Pediatric dentists (33%) reported encountering barriers when attempting to refer their patients to an endodontist. Inability to find an endodontist that participates with dental insurance was the most frequently cited barrier. CONCLUSIONS: Limited clinician participation with dental insurance and gaps in insurance coverage for endodontic procedures appear to contribute to access to care barriers for pediatric patients.

A comparative analysis of public and private dental benefit payer types for the provision and outcomes of root canal therapy on permanent teeth of children and adolescents in Massachusetts.

BACKGROUND: Despite substantial increases in dental benefits and improvements in the use of dental services among children and adolescents in the United States, oral health disparities according to dental insurance payer type persist. METHODS: The authors used an all-payer claims (2013-2017) database to perform a comparative analysis of the provision and treatment outcomes of an endodontic procedure (root canal therapy) in the permanent teeth of a pediatric population aged 6 through 18 years, according to dental insurance payer type. Statistical analyses, including logistic regression, Cox proportional hazards regression, and the Kaplan-Meier method, were performed at person and tooth levels. RESULTS: Compared with privately insured children and adolescents, public-payer children and adolescent beneficiaries were more likely to have had root canal therapy (adjusted odds ratio, 1.91; 95% CI, 1.73 to 2.11) and had poorer treatment outcomes associated with the procedure (adjusted hazard ratio, 2.19; 95% CI, 1.53 to 3.14; P < .0001) during the study period. Those enrolled in private insurance were more likely to receive treatment from an endodontist (specialist in providing root canal therapy) (P < .0001). Amounts allowed and paid by the insurer were significantly higher for private payers (P < .001). CONCLUSIONS: There were significant differences in the provision and outcomes of endodontic treatment between privately and publicly insured children and adolescents. PRACTICAL IMPLICATIONS: Despite ostensibly equal access to care, differences in the provision of oral health care exist between privately and publicly insured patients. These differences may be contributing to persisting oral health disparities.

Apexification Outcomes in the United States: A Retrospective Cohort Study.

INTRODUCTION: This epidemiological analysis used procedure codes from dental insurance claims data to identify apexification cases and evaluate survival at the tooth-level. METHODS: Dental insurance claims data from New York State (2006-2019) and Massachusetts (2013-2018) were used in an observational, retrospective cohort study to evaluate the provision and treatment outcomes of apexification. Statistical analyses included Kaplan-Meier survival estimates and Cox proportional hazards regression. Cox proportional hazard regression was used to evaluate the hazard of adverse event occurrence by age, gender, tooth type, placement of permanent restoration, and dental provider type. A sensitivity analysis evaluated potential bias in the survival estimates and adjusted hazard ratios (aHRs) due to differential loss to follow-up. Robust standard errors were used to account for potential dependence between teeth within an individual. RESULTS: The analytic cohort of 575 individuals included 632 teeth, with an average follow-up time of 64 months. The survival rates of apexification procedures were 95% at 1 year; 93% at 2 years; 90% at 3 years; and 86% at 5 years. Tooth retention following apexification was 98% at 1 year; 96% at 2 years; 95% at 3 years; and 90% at 5 years. Tooth type and subsequent placement of a permanent restoration were significant predictors of survival after apexification. CONCLUSIONS: The procedural and tooth survival outcomes of apexification were high and comparable to studies that analyzed clinical data on tooth survival following apexification.

Exploring Public Perceptions of Dental Care Affordability in the United States: Mixed Method Analysis via Twitter.

BACKGROUND: Dental care expenses are reported to present higher financial barriers than any other type of health care service in the United States. Social media platforms such as Twitter have become a source of public health communication and surveillance. Previous studies have demonstrated the usefulness of Twitter in exploring public opinion on aspects of dental care. To date, no studies have leveraged Twitter to examine public sentiments regarding dental care affordability in the United States. OBJECTIVE: The aim of this study is to understand public perceptions of dental care affordability in the United States on the social media site, Twitter. METHODS: Tweets posted between September 1, 2017, and September 30, 2021, were collected using the Snscrape application. Query terms were selected a priori to represent dentistry and financial aspects associated with dental treatment. Data were analyzed qualitatively using both deductive and inductive approaches. In total, 8% (440/5500) of all included tweets were coded to identify prominent themes and subthemes. The entire sample of included tweets were then independently coded into thematic categories. Quantitative data analyses included geographic distribution of tweets by state, volume analysis of tweets over time, and distribution of tweets by content theme. RESULTS: A final sample of 5314 tweets were included in the study. Thematic analysis identified the following prominent themes: (1) general sentiments (1614 tweets, 30.4%); (2) delaying or forgoing dental care (1190 tweets, 22.4%); (3) payment strategies (1019 tweets, 19.2%); (4) insurance (767 tweets, 14.4%); and (5) policy statements (724 tweets, 13.6%). Geographic distributions of the tweets established California, Texas, Florida, and New York as the states with the most tweets. Qualitative analysis revealed barriers faced by individuals to accessing dental care, strategies taken to cope with dental pain, and public perceptions on aspects of dental care policy. The volume and thematic trends of the tweets corresponded to relevant societal events, including the COVID-19 pandemic and debates on health care policy resulting from the election of President Joseph R. Biden. CONCLUSIONS: The findings illustrate the real-time sentiment of social media users toward the cost of dental treatment and suggest shortcomings in funding that may be representative of greater systemic failures in the provision of dental care. Thus, this study provides insights for policy makers and dental professionals who strive to increase access to dental care.

A comparative analysis of outcomes of root canal therapy for pediatric medicaid beneficiaries from New York State.

Objectives: This study investigated differences in the provision of root canal therapy and outcomes in a publicly insured cohort of children and adolescents. Methods: New York State Medicaid administrative claims from 2006 to 2018 were analyzed. Enrollees aged 6-18 were included in the study if they had initial non-surgical root canal therapy (NSRCT), in the permanent dentition, that allowed for at least 1 year of post-treatment follow-up. Descriptive analyses, multivariable logistic regression, and multivariable Cox proportional hazard models were used to examine the association between demographic variables (gender, age, race/ethnicity, and area-based factors) and dental treatment provision and outcomes. Results: Male gender was associated with having more than one initial NSRCT (adjusted odds ratio (aOR) = 1.06; 95% confidence interval (CI) = 1.02-1.10), as was rurality (aOR = 1.15; 95% CI = 1.06-1.24). Black/African American (AA) and Hispanic children were less likely than non-Hispanic white children to have multiple NSRCTs (aOR = 0.88; 95% CI = 0.83-0.93 and aOR = 0.78; 95% CI = 0.74-0.83). Being older or female conferred a lower hazard of an untoward event (aHR = 0.93; 95% CI = 0.92-0.94 and aHR = 0.86; 95% CI = 0.81-0.91). Compared to non-Hispanic white children, Hispanic and Black/AA children had a higher risk of untoward event (aHR = 1.31; 95% CI = 1.21-1.41 and aHR = 1.55; 95% CI = 1.43-1.67) while children of Asian descent had a lower incidence after initial NSRCT (aHR = 0.79; 95% CI = 0.71-0.88). Conclusion: Race/ethnicity was the strongest demographic predictor of provision of initial non-surgical root canal therapy, subsequent placement of a permanent restoration and the occurrence of an untoward event after NSRCT in this cohort.
