Gingival Cleft, Orthodontic Space Closure
Conditions
Keywords
gingival cleft, Orthodontic Space Closure, gingiva, gingival disease, tooth extraction, tooth socket
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| presence of gingival clefts after space closure initiation | start of canine retraction to its completion (approximately 6 months) | The primary outcome will be the presence of gingival clefts, which will be measured at 3 months and 6 months after space closure initiation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| craniofacial growth pattern | craniofacial growth pattern will be measured at baseline | craniofacial growth pattern from sum of posterior angles |
| gingival biotype | At baseline (immediately prior to tooth extraction) | gingival biotype by measuring thickness of gingiva using spreader of size 15 |
| buccal bone dehiscence | Immediately post extraction | 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. |
| canine bulbosity | will be measured at baseline | Maximum height of contour of canine will be measured on the pretreatment cast using the digital vernier caliper |
