Survival analysis of crown margin repair

Dentists sought to understand the factors influencing the lifespan of tooth crown repairs, particularly the role of various dental materials. My contribution involved addressing the critical need for evidence-based insights by extracting and analyzing complex data from electronic health records. I collaborated closely with both the dental researchers and IT specialists to curate a robust dataset, meticulously validating the “time-to-event” outcome critical for this study. Through careful statistical modeling and rigorous data analysis, I generated a comprehensive report. The findings provided compelling evidence that dental material significantly impacts crown longevity, revealing that some materials are associated with a 1.5 to 2 times higher probability of needing re-intervention. These crucial results were subsequently published in an open-access dental journal (Jain et al., 2022), directly empowering dentists to make informed, evidence-based decisions in their practice, ultimately leading to improved oral health outcomes for patients.
