Gingival Cleft Development at Two Time Points of Canine Retraction

Bahria University19 enrolled

Overview

The goal of this split-mouth randomized controlled trial is to assess whether the timing of extraction space closure-early vs. delayed initiation-affects the incidence of gingival cleft development in orthodontic patients. The main question it aims to answer is: Does the incidence of gingival cleft development get influenced by the specific time point at which orthodontic space closure is initiated following extraction? Quadrants will be assigned to the early movement group and the other to the delayed movement group and extractions will be performed accordingly. These will be assessed for the effect on development of gingival cleft development.

Inclusion Criteria: 1. Extraction advised of both first premolars from either maxilla, mandible or both. 2. All permanent dentition present apart from third molars. Exclusion Criteria: 1. Severe crowding 2. Smokers 3. Patients with systemic diseases that could interfere with bone remodeling. 4. Patients with periodontitis or poor periodontal health. 5. Patients who have previously undergone periodontal surgery in the area of interest. 6. Patients with other oral health conditions that could complicate the treatment or healing process.

Outcomes

Primary Outcomes

presence of gingival clefts after space closure initiation

The primary outcome will be the presence of gingival clefts, which will be measured at 3 months and 6 months after space closure initiation

Time frame: start of canine retraction to its completion (approximately 6 months)

Secondary Outcomes

craniofacial growth pattern

craniofacial growth pattern from sum of posterior angles

Time frame: craniofacial growth pattern will be measured at baseline

gingival biotype

gingival biotype by measuring thickness of gingiva using spreader of size 15

Time frame: At baseline (immediately prior to tooth extraction)

buccal bone dehiscence

bone dehiscence will be measured utilizing the periodontal probe(in mm) from the distal marginal ridge of premolar as reference point, on both the buccal and palatal/lingual side.

Time frame: Immediately post extraction

canine bulbosity

Maximum height of contour of canine will be measured on the pretreatment cast using the digital vernier caliper

Time frame: will be measured at baseline
