    Aim: The aim of the study was to estimate the normal mouth opening in adults. Background: Mouth opening varies from individual to individual and among the different population. There are many factors such as gender, race, and age which contribute to the variation in the range in normal mouth opening. The current study is an attempt to calculate the normal mouth opening in adult Chennai population. Normal mouth opening or maximal mouth opening (MMO) can be described as the distance between the incisal edge of maxillary central incisor to the incisal edge of mandibular central incisor when the mouth is opened as wide as possible without any difficulty. Materials and Methods: A total of 100 adults, from children to older people were studied. The subjects were asked to open their mouths maximally until no further opening was possible. Then, the distance between the incisal edges from the maxillary central incisor to the mandibular central incisor was measured using a calibrated ruler. Results: The average MMO for males and females was 48.5 mm. The range was 34–69 mm. The average MMO for males was 52 mm. The range was 39–69 mm. The average MMO for females was 45 mm. The range was 34–56 mm. It was observed that females had a smaller range than males. The range also decreases with age. Conclusion: The study showed that numerous factors such as age, sex, and race were responsible in variations in MMO. The normal mouth opening was found to be lesser in females as compared to males and also decreases with age. This study is relevant for surgical procedures such as temporomandibular joint diseases, craniofacial syndromes, and maxillofacial surgery.
