229 - New Treatment Needs Following Full Mouth Dental Rehabilitation Within 2 Years

Purpose:

The aim of this study was to determine the percentage of patients needing treatment due to new carious lesions within 2 years of full mouth dental rehabilitation under general anesthesia.

Methods:

A 10-year retrospective chart review of electronic health records (axiUm) of cases of full mouth dental rehabilitation (FMDR) completed at Tufts University School of Dental Medicine from 1/1/2009 to 12/31/2019 was completed, ages 1-12. Information collected included type of treatment completed, how many teeth needed treatment, type of treatment modality, age at FMDR, gender, ethnicity, and insurance type. Associations were assessed using the chi-square test, with binary logistic regression and negative binomial regression also used to adjust for potential confounders.

Results:

Out of 1441 charts that were reviewed, 864 charts (one per subject) were included in the study. Of these subjects, 499 (58%) had new treatment needs within 2 years (95% CI: [55%, 61%]). Ethnicity was significantly associated with new treatment needs (P=.022). Age and ethnicity were significantly associated (P < .05) with new treatment needs when adjusting for the other independent variables, and significantly associated (P < .05) with the number of teeth needing treatment following FMDR. Patients aged 0-2 at time of FMDR needed on average 2 times more teeth treated compared to older patients.

Conclusion:

The majority of patients following FMDR will have new treatment needs within 2 years. Non-Hispanic ethnicity and younger patient age at time of FMDR may play a factor into likelihood of new treatment needs.
