Official title
Studio Retrospettivo Monocentrico di Una Coorte di Pazienti Affetti da Lichen Planus Orale: Caratteristiche, comorbilità e Fattori di Rischio Per la Trasformazione Maligna
Overview
This case-control study will enroll 176 patients age- and sex- matched at the Oral Medicine Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome. There will be two groups: The control group will consist of 88 healthy patients enrolled among those routinely attending the dental outpatient clinic. An additional 88 patients diagnosed with OLP will form the case group. Both groups will undergo standard dental examinations, including periodontal probing. The primary objective is to evaluate whether patients with OLP present a higher prevalence and severity of periodontitis compared to healthy subjects. Secondary objectives include the assessment of gingivitis prevalence and RT1 gingival recessions in OLP patients compared with controls. Periodontal status will be assessed using major clinical indices and classified according to the 2017 AAP/EFP case definition. The study aims to contribute evidence on the shared immune-inflammatory mechanisms underlying both conditions, with potential clinical implications for the integrated periodontal management of OLP patients.
Primary outcome measures
- Rate of periodontitis in OLP patients compared with age- and sex-matched healthy controls, classified according to the 2017 AAP/EFP staging and grading system [Time frame: From 20 of May to 15 of June]
