DETRIMENTAL EFFECTS OF GINGIVAL BIOTYPE ON POST ORTHODONTIC TREATMENT PATIENTS INDUCED GINGIVAL RECESSION. A RETROSPECTIVE STUDY

Abstract Introduction: Accurately assessing periodontal tissue dimensions before orthodontic treatment is essential, because it influences its aesthetic outcome. [...]the objectives of this retrospective study were: (i). to mainly focus on the development of new gingival recession and associated changes in gingival biotype after orthodontic treatment and (ii). also to examine changes (improvement, worsening or no change) in preexisting gingival recession and gingival biotype after orthodontic treatment. Conclusions: Correction of proclination and crowding of teeth by orthodontic treatment and its positive impact on gingival recession with a thin gingival biotype showed a significant association Keywords: gingival biotype, gingival recession, orthodontic treatment. 1.INTRODUCTION Gingival recession (GR) is defined as the apical shift of the gingival margin with respect to the cemento-enamel junction (CEJ). [...]usually, the main factors for GR development are the presence of gingival retraction before orthodontic movement, poor oral hygiene, gingivitis and/or a thin gingival/ bone biotype, together with proclination of incisors [17]. [...]the objectives of this retrospective study were: 1. MATERIALS AND METHODS Source of data The present study follows a retrospective observation on 200 plaster models of both male and female subjects between 22 to 55 years of age who have completed the treatment in the Orthodontic Department at College of Dentistry, "King Khalid" University, Saudi Arabia.
