Assessment of Oral Health in Minors Incarcerated at Fleury Merogis: Retrospective Observational Study (DENTMIN)

The goal of this study is to assess the oral health of males juveniles incarcerated at Fleury-Mérogis over a given period.

The goal is also to understand the needs of these patients and improve their care in prison while raising awareness about oral health to achieve lasting results.

Hypothesis: Incarcerated juveniles often grew up in precarious conditions. Is their DMFT (decayed, missing, filled permanent teeth) index higher than the "standard" juvenile population? Public interest: Understanding the needs of these juvenile patients, public health data.

By comparing our results to those of the "standard" population (non-incarcerated minors) through a literature review regarding the DMFT index in these patients, we will determine whether incarcerated juvenile patients represent a population at risk of developing oral pathologies. Oral disease prevention for these patients to raise awareness of the importance of oral hygiene and follow-up dental appointments outside of the prison system. The earlier these patients are educated, the greater the chance they will develop better habits throughout their lives.

Study Overview

• Status: Completed
• Conditions: DMFT Index, ICDAS Score, Dental Plaque Index, Communication, Prevention, Dentist, Orthodontist
• Intervention / Treatment: Other: questionnaire and dental clinical examination

Detailed Description

This is a retrospective observational study in which we will collect data from the first dental consultation between June 2024 and December 2024.

The primary objective is to assess the oral health of minors incarcerated at Fleury-Mérogis using the primary outcome measure, the DMFT index.

77 male minors are included in the study. Data will be collected retrospectively by the research team from their medical records.

The data will be collected by the research team in a pseudo-anonymized form in an electronic CRF (case report form) and then analyzed by the biostatistician at the Clinical Research Unit of the Centre Hospitalier Sud Francilien.
