ABSTRACT


Aim: Evaluation Of Gingival Biotypes And Width Of Keratinized Gingiva Of Anterior Teeth In Adults With Abnormal Skeletal Jaw Relations. Methodology: This Cross-sectional Study Included 182 Orthodontic Patient With Skeletal Class II And Skeletal Class III Pattern (74 Males, 108 Females) Who Applied For Orthodontic Treatment In Faculty Of Dentistry, Cairo University Starting From November 2018 October 2019. They Were Included Based On Wit;s Appraisal Measured On Lateral Cephalometric Radiograph Taken As A Record For Orthodontic Treatment. They Were Further Divided Into Six Groups Based On Vertical Growth Pattern According To Facial Axis Angle. Gingival Biotypes For The Anterior Teeth Have Been Determined Either Thick Biotype Or Thin Biotype Using Probe Transparency Method. Width Of Keratinized Gingiva Has Been Measured For Each Anterior Tooth Using Digital Caliper.

Results: The Results Of This Study Have Showed Statistical Significantdecrease In The Percentage Of Thin Gingival Biotypes In Upper Anterior Teeth In Skeletal Class II Patients With Hyperdivergent Growth Pattern. Also There Was A Statistical Significantincrease In The Distribution Of Thin Gingival Biotypes In Lower Anterior Teeth In Skeletal Class II Patients With Normal Vertical Growth Pattern And Skeletal Class III Patients With Hyperdivergent Growth Pattern. Width Of Keratinized Gingiva Of Anterior Teeth Seems Not To Be Correlated With Different Skeletal Sagittal And Vertical Malocclusion Patterns. Conclusion: Thin Gingival Biotype Is More Distributed In Lower Anterior Teeth In Skeletal Class II Patients With Normal Growth Pattern And Skeletal Class III Patients With Hyperdivergent Growth Pattern. Thick Gingival Biotype Is More Prevalent In Upper Anterior Teeth In All Skeletal Malocclusion Groups With The Most Prevalence In Skeletal Class II Patients With Hyperdivergent Growth Pattern
