Tongue movement and function associated with sex dimorphism in young adult ankyloglossia: a pilot study
Main Article Content
Abstract
Ankyloglossia defined as short and fibrous appearance of lingual frenulum, that plays an essential part in oral and maxillofacial system. The aim of this study was to investigate the association between gender and tongue mobility and function in young adult ankyloglossia. This case control study composed of 10 patients: 5 control patients and 5 ankyloglossia. Age, gender, height, weight and body mass index (BMI) were recorded. The ankyloglossia was characterized as free tongue movement. The tongue parameters, including maximal interincisal mouth opening (MIO), mouth opening with tongue tip to maxillary incisive papillae (MOTTIP), tongue range of motion ratio (TRMR), tongue mobility, and maximum tongue pressure, were observed. The free tongue movement (rs = 0.771, p < 0.05), tongue range of motion ratio (rs = 0.810, p < 0.05) and tongue mobility (rs = 0.932, p < 0.01) were significantly correlated with BMI in male. Additionally, positive correlations were shown between sex and free tongue movement (rs = 0.574, p < 0.05) and tongue mobility (rs = 0.538, p < 0.05) respectively. The analysis showed ankyloglossia as a higher predictor for male with odd ratio 0.67 (95% CI 0.005-0.970, p < 0.05). The findings suggested gender-related differences with tongue movement and function in ankyloglossia. Females had higher tongue movement in normal subjects, whether males had higher tongue limitations in ankyloglossia. Moreover, BMI seemed to be an influential factor in free tongue movement, the tongue of motion ratio and tongue mobility in male.
