ASSESSMENT OF PERIODONTAL TISSUE STATUS IN STUDENTS AT CAN THO UNIVERSITY OF MEDICINE AND PHARMACY USING INTRAORAL SCANNER AND DIGITAL PHOTOGRAPHY
Main Article Content
Abstract
Background: In the context of increasing demands for more accurate periodontal tissue assessment, comparing digital photography and intraoral scanning plays an important role in optimizing the prevention, diagnosis, and monitoring of periodontal diseases. Objective: To determine the degree and location of gingival pigmentation in the anterior region of both jaws using digital photography and intraoral scanning among students at Can Tho University of Medicine and Pharmacy in 2024; and to compare the levels of gingival recession in the anterior region of both jaws between digital photography and intraoral scanning among these students. Materials and methods: The study participants were students attending Dental Clinic 2 of Can Tho University of Medicine and Pharmacy Hospital. An analytical cross-sectional study was conducted on 520 students aged 18–30 years, who were evaluated simultaneously using digital photography and intraoral scanning. Results: Although the two methods showed a high level of agreement, the Wilcoxon signed-rank test revealed statistically significant differences in Miller’s gingival recession classification at certain tooth sites, including R13 (p = 0.008) and R33 (p = 0.002). However, no significant differences were observed at most of the remaining teeth. The two methods showed a very high level of agreement (Kappa > 0.7) in determining the degree and location of gingival pigmentation according to the Takashi index. Conclusion: Digital photography and intraoral scanning showed a high level of agreement in assessing gingival recession in the anterior region of both jaws and gingival pigmentation according to the Takashi index. Intraoral scanning has an advantage in acquiring three-dimensional data and supporting morphological observation, whereas digital photography remains valuable for recording soft tissue color. The combination of both methods may provide a more comprehensive assessment of gingival recession and gingival pigmentation.
