Impact of the COVID-19 pandemic on oral health care use in the United States through December 2021.

BACKGROUND: The purpose of this study was to assess the effects of the COVID-19 pandemic on oral health care provided from July 2020 through December 2021 using national claims data. METHODS: Deidentified quarterly claims from 2017 through 2021 were analyzed (2017-2019 provided prepandemic data). Data were sorted into multiple treatment categories. Analyses compared prepandemic with postpandemic procedure volumes and were stratified according to age groups (0-5 years, 6-18 years, 19-64 years, ≥ 65 years). RESULTS: For children aged 0 through 5 years, use of sealants and topical fluorides other than varnish were considerably lower in 2021, as were direct operative and palliative procedures from 2020 through 2021. Only use of silver diamine fluoride, prefabricated crowns, and oral surgery increased significantly (P < .05) in some quarters. For children aged 6 through 18 years, diagnostic, direct operative, periodontic, oral surgery, and palliative procedures were significantly lower in most of 2020 through 2021, and only prefabricated crowns and indirect operative procedures increased significantly in more than 3 quarters. For adults aged 19 through 64 years, diagnostic and preventive procedures were significantly lower in 3 quarters, and direct operative, gingival surgery, endodontic, and palliative procedures were significantly lower in most of 2020 through 2021. Only occlusal guards and scaling and root planing increased significantly in more than 3 quarters. For adults 65 years and older, direct operative, gingival and osseous surgery, and palliative procedures were significantly lower in more than 3 quarters; all other procedures increased significantly in more than 3 quarters. CONCLUSIONS: The pandemic was associated with changes in the provision of oral health care that persisted for more than 1 year. PRACTICAL IMPLICATIONS: Reductions in preventive procedure volumes across age groups younger than 65 years may have implications for longer-term effects of the pandemic.

Impact of the COVID-19 pandemic on pediatric Medicaid dental claims in Arizona.

OBJECTIVES: To examine the role COVID-19 had on access to dental services among children in Arizona by comparing paid pediatric dental claims made before and during the pandemic. METHODS: In a retrospective descriptive study, we examined Medicaid paid claims for dental services among pediatric patients from March through December 2019 and during the outbreak in 2020. Using dental claims data obtained from the Centers for Health Information and Research at Arizona State University (ASU), we analyzed Medicaid (Arizona Health Care Cost Containment System [AHCCCS]) reimbursed dental services. RESULTS: During the COVID-19 pandemic, paid preventive dental claims for children aged birth to 21 years decreased in 2020 compared to the same time period in 2019. Pediatric patients in Arizona utilized fewer dental services and had less access to credentialed Medicaid dental providers during the pandemic. Further, rural counties had statistically significant fewer preventive, minor restorative, major restorative, and endodontic claims compared to urban counties. Arizona rural counties also had fewer providers who were paid $10,000 or more per year during 2020 than in 2019. CONCLUSIONS: COVID-19 has had a detrimental impact on pediatric dental service utilization. While dental services were provided during the COVID-19 pandemic, preventive and restorative dental claims dropped for rural Arizona children aged birth to 21 years. This reveals potential negative impacts on oral health. Further research should examine the direct and indirect impact the COVID-19 pandemic has had on dental service utilization and oral health for the general pediatric population.

Validity of diagnoses and procedures in Japanese dental claims data.

BACKGROUND: Dental claims data have been used for epidemiological studies without establishing the validity of the recorded diagnoses or procedures. The present study aimed to examine the accuracy of diagnoses, procedures, operation time, and the number of teeth recorded in dental claims data. METHODS: We reviewed the charts of 200 patients who visited and 100 patients who were hospitalized in the Department of General Dentistry, Orthodontics, and Oral and Maxillofacial Surgery in an academic hospital between August 2012 and December 2017. The sensitivity and specificity of the dental claims data for five diseases and 15 procedures were evaluated. We assessed the difference in the number of teeth and duration of general anesthesia between claims data and chart reviews. RESULTS: Sensitivity was more than 86% for six out of seven diagnoses except for pericoronitis (67%). Specificity ranged from 72% (periodontal disease) to 100% (oral cancer for inpatient). The sensitivity of procedures ranged from 10% (scaling for inpatient) to 100%, and the specificity ranged from 6% (food intake on the day of the surgery) to 100%. The mean (standard deviation [SD]) number of teeth in the chart review was 22.6 (6.8), and in the dental claims was 21.6 (8.6). The mean (SD) operation time was 171.2 (120.3) minutes, while the duration of general anesthesia was 270.9 (171.3) minutes. CONCLUSIONS: The present study is the first study to validate dental claims data, and indicates the extent of usefulness of each diagnosis and procedure for future dental research using administrative data.

Dental treatment injuries in the Finnish Patient Insurance Centre in 2000-2011.

Objective The Patient Insurance Centre in Finland reimburses patients who sustained injuries associated with medical and dental care without having to demonstrate malpractice. The aim was to analyse all dental injuries claimed through the Patient Insurance Centre over a 12-year period in order to identify factors affecting reimbursement of claims. Methods This study investigated all dental patient insurance claims in Finland during 2000-2011. The injury cases were grouped as (K00-K08) according to the International Classification of Diseases (ICD-10). Calendar year, claimant's age and gender, dental disease group and health service sector were the explanatory factors and the outcome was the decision of a claim. Multiple logistic regression modelling was used in the statistical analyses. Results The total number of decisions related to dental claims at the PIC in 2000-2011 was 7662, of which women claimed a clear majority (72%). Diseases of the pulp and periapical tissues (K04) and dental caries (K02) were the major disease groups (both 29%). Of the claims 40% were eligible for reimbursement, 27% were classified as insignificant or unavoidable injuries and 32% were rejected for other reasons. The proportion of reimbursed claims declined during the period. Patients from the private sector were more likely to be eligible for compensation than were those from the public sector (OR = 1.89, 95% CI = 1.71-2.10). Conclusions The number of dental patient insurance claims in Finland clearly rose, while the proportion of reimbursed claims declined. More claims received compensation in the private sector than in the public sector.
