Abstract. Introduction: The occurrence of dental erosion (DE) involves the prolonged contact of acids of extrinsic and intrinsic origin with the
tooth tissues, without intervention of pathogenic bacteria. Gastro esophageal reflux disease (GERD) is one of the most common disorder of digestive
tract causing several extra-esophageal manifestations including impacting the hard dental structures. Objective: We investigate the distribution/severity
and the relationships of DE with associated factors in patients from two French medical centers involved in an international
AUF project: Digestive Diseases Institute, University of Nantes and Faculty of Dentistry Victor Segalen, University of Bordeaux. Material and
method: A total of 119 patients comprising 77 (64.7%) female and 42 (35.3%) male, mean age 43.81± 14.42 years were included in the study.
Two questionnaires regarding alimentary habits, lifestyle, general and digestive diseases and medications associated that favor the occurrence
of DE and gastro-esophageal reflux were completed. Oral examination to quantify the severity of DE was done using the Basic Erosive Wear
Examination Index. Buccal (B), palatal/ lingual (P /L) and occlusal (O) / incisal (I) surfaces are examined and the highest score was recorded.
Results: DE scores were higher on the palatal/ lingual and incisal surfaces of the anterior teeth and the palatal/lingual and occlusal surfaces
of the posterior teeth in patients with GERD. No statistically differences were found between DE scores and age, gender, diet or medications.
Conclusion: The most affected surfaces by DE in the presence of GERD were the palatal/ lingual and incisal surfaces of the anterior teeth and
the palatal/lingual and occlusal surfaces of the posterior teeth.

Key Words: dental erosion, risk factors, gastro-esophageal reflux.
