SURVEY ON THE MUCOSA HARD PALATE OF THE PATIENTS TREATMENT AT HOSPITAL OF ODONTO-STOMATOLOGY HO CHI MINH CITY IN 2023
Main Article Content
Abstract
Background: The mucosa hard palatine is the commonly used area for grafting of connective tissue. The thickness of the collected connective tissue graft has an important role in determining the viability of the graft, the healing method and the clinical outcome of the gingival-mucosal surgery. Materials and Methods: a descriptive cross-sectional study was conducted on patients treated at the Ho Chi Minh City Odonto-Stomatology Hospital, from May 2022 to September 2022. Objectives: Determine the thickness of the adult hard palate by CT Cone Beam at teeth 3,4,5,6,7 with positions 2mm, 5mm, 8mm away from the gum line. Results: The study showed that the average thickness of the hard palate mucosa at tooth 3 (3.25±0.57), tooth 4 (3.37±0.68), tooth 5 (3.21±) 0.88) is higher than tooth position 6 (2.88±0.58) and tooth position 7 (2.92±0.84), the difference is statistically significant (p=0.001). Besides, the thickness of the palatal mucosa is greatest at the position of 8mm tooth 3 (3.85±0.64). The thickness of the palatal mucosa is the smallest at the position of 5mm of tooth 7 (2.40±0.782). The sites with palatal mucosal thickness greater than 3mm are the 5mm, 8mm positions of R3; 8mm position of tooth 4; position 5mm, 8mm of tooth 5; 8mm position of teeth 6, 7. Conclusion: cone-beam computed tomography can be used as a non-invasive means to accurately and uniformly determine the thickness of the hard palate mucosa with the help of a film trough. The most suitable area to take a connective tissue graft is tooth 3, tooth 4, tooth 5.
