RESUMEN
PURPOSE: This study aims to determine the number, symmetry, shape and individual characteristic of palatal rugae. METHODS: In our study, we performed on subjects ages 16 to 57 (23.01â±â7.12), ranging from a total of 230 (108 female and 122 male). Alginant impression material from each took dimensions of the upper jaw. Then casts were obtained by pouring hard casts. The shapes, lengths, and directions of rugae measured on these casts. The palatine photos were taken by using a mobile phone-Samsung brand with 12 MP camera and an orthodontic mirror. The casts and photographs were selected at random belonging to 100 subjects. Selected at random 10 photographs were matched among 100 casts. The ratios of correct matches were determined. RESULTS: In our study, the total number of palatal rugae was found as 9.49â±â1.87 in females and 9.42â±â1.92 in males. The most detected rugae pattern was wavy on both females and males. The most rarely seen rugae pattern was converged in the males and circular in the females. Regarding lengths of rugae, the most detected rugae pattern was the primary one. Regarding the direction of rugae pattern, positive-sided one was the most dominant in both genders. We determined the ratio of matching the casts belonging to Palatine with the photos as 63.5%. The number of rugae aged under 18 and above 41 was found to be statistically significant (Pâ=â0.003), but the number of curved and positive-sided rugae in older ages was not found to be statistically significant. CONCLUSIONS: Compared with data from earlier studies, the shapes, length, and direction of palatal rugae were seen specific in every individual, and it was seen to have discriminating characteristics among different populations. The possible differences in individual specific palatal rugae require further studies involving larger samples.
