15. LEVEL OF GUMMY SMILE AND SOME CAUSES AMONG PATIENTS COMING FOR MEDICAL EXAMINATION AND TREATMENT
Main Article Content
Abstract
Objective: Describe the clinical characteristics of gummy smile and some causes in the group of patients visiting the National Hospital of Odonto - Stomatology and the Institute of Odonto - Stomatology Training, Hanoi Medical University in 2023.
Method: A cross-sectional study design on 40 patients with gummy smile at maximum smile, aged 18-35, without maxillofacial deformities. Data were collected through clinical examination, photography and observation of the study subjects and analyzed by SPSS software.
Results: Straight smile arc had the highest proportion, followed by parallel smile arc and the least was inverted smile arc. The exposure of the upper incisors in the resting position increased statistically significantly and had a moderate positive linear correlation with gummy smile. People with gummy smile have a 0.93 mm reduction in the height of the upper central incisor, a 1.67 mm reduction in the height of the philtrum, and a 1.5 mm increase in the maximum mobility of the upper lip when smiling compared to the normal mobility limit. Excessive upper lip mobility when smiling is the characteristic with the highest percentage (75%). 30% of subjects have gummy smile due to at least two causes, 5% of subjects have a combination of all three causes.
Conclusion: Patients with gummy smile need to continue to analyze photos, draw films, and analyze cephalometric films to have appropriate treatment methods.
