Evaluation of Gingival Biotypes of Anterior Teeth in Adults With Abnormal Skeletal Jaw Relations

3. april 2018 oppdatert av: Ahmed magdy Mohamed Sabrah, Cairo University

Evaluation of Gingival Biotypes and Width of Keratinized Gingiva of Anterior Teeth in Adults With Abnormal Skeletal Jaw Relations: A Cross-sectional Study

The aim of this study is to evaluate gingival biotypes and width of keratinized gingiva in the anterior region of adults with abnormal skeletal jaw relations.

Detaljert beskrivelse

This study will include consecutive adult patients seeking orthodontic treatment with skeletal Class II and Class III jaw relations based on clinical and cephalometric values. Each group will be further divided according to their vertical skeletal pattern. Gingival biotype will be determined -using the probe transparency method- into either thick or thin biotype for all anterior teeth in both jaws. Width of keratinized gingiva will be measured from the muco-gingival junction to the free gingival margin in the middle of the crown of the maxillary and mandibular anterior teeth using a digital caliper with a sensitivity of 0.01 mm. Statistical analysis will be applied to see the correlation between gingival biotypes , width of keratinized gingiva , and abnormal skeletal jaw relations.

Kohorter og intervensjoner

Gruppe / Kohort
Intervensjon / Behandling
Skeletal Class II Group
From the lateral cephalometric radiograph , Steiner analysis (ANB angle should be higher than mean value, mean value 3 ±2), Witt's appraisal should be higher than mean value (mean value zero), and McNamara analysis (A-B diff NV should be higher than mean value, mean value 4±2).At least two of the three mentioned analyses should verify skeletal class II relation
Annen: exposure will be abnormal skeletal jaw relations
Class II skeletal jaw relation or class III skeletal jaw relation based on lateral cephalometric radiograph
Skeletal Class III Group
From the lateral cephalometric radiograph , Steiner analysis (ANB angle should be lower than mean value, mean value 3 ±2), Witt's appraisal should be lower than mean value (mean value zero), and McNamara analysis (A-B diff NV should be lower than mean value, mean value 4±2).At least two of the three mentioned analyses should verify skeletal class III relation
Annen: exposure will be abnormal skeletal jaw relations
Class II skeletal jaw relation or class III skeletal jaw relation based on lateral cephalometric radiograph

Tidsramme
Correlation between gingival biotypes and abnormal sagittal skeletal jaw relations.
Tidsramme: 6 months
Gingival biotype will be determined using the probe transparency method, in which probing is done in the sulcus at the mid facial aspect of maxillary and mandibular incisors and canines by a periodontal probe. Gingival thickness will be classified as thin when the underlying periodontal probe outline can be seen through the gingiva; otherwise, it will be considered thick. Results of the twelve anterior teeth will be recorded for each patient in a tabulated form. Statistical Analysis will be done to detect the correlation between gingival biotypes (Thick or thin ) and abnormal sagittal skeletal jaw relation ( skeletal class II or skeletal class III 9
