The purpose of this study was to evaluate the success and survival of anterior primary teeth that have had interproximal discing completed. Two hundred and seventy- five teeth that had discing completed on either the mesial and/or distal surfaces were included in this study (n=275). Data included patient’s gender, health status, age at time of treatment, date of initial treatment, depth of caries (into enamel or into dentin), clinical findings post treatment, and all post operative visits. Descriptive statistics (frequency, mean, standard deviation), independent sample t test, chi-square test, logistic regression and Kaplan-Meier survival analysis were used to analyze the data. The majority of teeth that had discing completed were central incisors (#E,F) and the overall success rate for teeth that had interproximal discing completed was 92%. Difference in survival time of teeth with caries into dentin vs. enamel was not statistically significant. Age at time of completion, depth of caries (into dentin or into enamel) and amount of follow up time were statistically significant factors. These findings indicate that interproximal discing is a viable treatment option of primary maxillary anterior teeth that have caries on the mesial or distal surfaces and future clinical trials are encouraged.
