PERCEPTION OF FEMALE DENTAL STUDENTS TO SOME GINGIVAL DEFECTS
The main objective of this study was to assess the perception of smile attractiveness towards four periodontal defects; namely: gingival recession (GR), gingival pigmentation (GP), black triangle (BT) and gummy smile (GS) among female dental students (n=100) in five academic levels at College of Dentistry, King Saud University, Saudi Arabia. Fifteen standardized altered smile images, representing the four defects at varying severities, were displayed to the students in a power point. A questionnaire with visual analog scale (VAS) was used to estimate the perception to each defect at each severity (1500 responses). The perception score was based on a scale of 0-100, where 0= the defect is strongly unattractive, and 100= the defect is relatively attractive. Results showed that PG defect was the relatively most (p ≤0.05) attractive defect, whereas GR was the most unacceptable defect. Generally, perception scores decreased significantly (p ≤ 0.05) as the severity of each defect was increased. Education level of students had a strong effect; students at higher academic levels were more accurate and have more critical eyes than students in lower level.
