Frenum is a thin mucous membrane fold which is enclosed by muscle fibers that attach the lips to the alveolar mucosa and the underlying periosteum. The high frenal attachment leads to spacing (diastema), gingival recession,interference in prosthodontics treatment and speech difficulty. The treatment frenectomy is mainly done to correct high frenal attachment.The aim of the study was to find the common reasons for frenectomy and the other factors associated with high frenal attachment . This retrospective study included the patients who underwent frenectomy/ frenotomy for high frenal attachment in a dental hospital from June 2019 to March 2020. No gender or age restrictions were. 99 patients were included in the study. Digital case sheets were reviewed and the following data including the details like patients gender, age, site of high frenal attachment, reason for frenectomy were extracted, tabulated and analysed statistically with Chi square test using SPSS version 20. Among those 99 frenectomy cases. The males were ( 43.4%) and females were (56.6%). The prevalence of frenectomy was more in female gender as compared to male gender. The common reason behind frenectomy was spacing (61.6%) and the more common site of high frenal attachment was S2 (Maxillary anterior sextant) (55.5%) compared to S5 (Mandibular anterior sextant). There was a significant difference in the reasons for frenectomy between site(p < 0.05 )and sites underwent frenectomy and age of the patient(p < 0.05).No significant difference in the reasons for frenectomy between males and females (p > 0.05). From the study it can be concluded that the common reason for frenectomy is diastema and the reasons for frenectomy is influenced by the site of high frenal attachment and the age of the patients.
