Aim: The aim of this retrospective study was to assess the frenum attachment recurrence and evaluate clinical parameters after conventional and diode laser-assisted frenectomy in patients with different abnormal frenum insertions.

Methods: Data records of 429 patients treated with maxillary labial frenectomy between January 1, 2016 and January 1, 2018 were screened. Records of 70 patients meeting the inclusion criteria were evaluated. Data were analyzed in terms of gender, age, category of frenum, presence of diastema, operation technique, type of periodontal disease. The distance between frenum attachment and mucogingival junction (FMGJ), plaque index (PI), gingival index (GI) and probing depth were assessed.

Inclusion Criteria:

(a) systemically healthy, (b) nonsmoker, (c) aged between 18 and 65 years, (d) received initial periodontal treatment before frenectomy, (e) presence of central and lateral incisors and canines at maxilla, (f) not received any kind of periodontal surgery, prosthodontic and restorative treatment which may affect the anatomy of the relevant region.
