0%; Table 4). Table 3 illustrates Imatinib Mesylate solubility the fact that male individuals presented with extracted teeth approximately 4 times more frequently than females, although this difference was not statistically significant (P=0.05). No canine extraction was seen in this group. Intraarch measurements Diastemas and crowding In DMI, 44 subjects (20.6%) had crowding and 40 (18.7%) had diastemas in their dental arches. There were 29 males and only 15 females who had crowding (Table 2). In this research, crowding was divided into three groups: slight (0�C2 mm crowding in any dental arch), moderate (2�C4 mm), and severe (more than 4 mm). The distribution of subjects according to gender and severity of crowding is presented in Table 2. Extra data Oral hygiene Of all the participants, 49 (30.0%) DMI had good oral hygiene, 48 (29.

0%) had moderate hygiene, and 67 (41.0%) had poor oral hygiene (Table 5). There were statistically significant differences between genders who had good (P<.001), moderate (P<.05), and poor oral hygiene (P<.05). Table 5. Distribution of additional data between genders. Esthetic satisfaction Table 5 shows that 80 (81.0%) DMI were satisfied with their esthetics, whereas 19 (19.0%) were not. DISCUSSION Teeth are positioned in equilibrium, in the dental arch between the opposing forces of the lips and tongue. However, additional forces or tonus changes applied to the teeth over extended periods of time will upset the alignment of the dental arch, creating a malocclusion.

9 There is research proposing that prelingually deafened talkers do not displace the tongue in order to establish vowel steady-state postures and excessively displace the jaw, and that deaf subjects appear to have a less flexible tongue during speech production than do hearing subjects.8 Considering this difference, the present study evaluates the occlusal characteristics of deaf-mute individuals in the city of Ankara. Because the study group contains students from various parts of Anatolia, it is assumed to be a good representation of the Turkish population. Because of the large and widely scattered sample group, we used malocclusion record forms approved by the FDI for this study. This form was initially used for normal individuals in a study11 and we used it as an opportunity to compare those results with our own.

Interarch and intraarch measurements are evaluated separately because malocclusions have different features11 which do not permit grouping. The prevalence of different types of malocclusions may show great variability even Batimastat in a population of the same origin; Thilander et al12 reports that malocclusion prevalence varies from 39.0% to 93.0%. According to our results, 75.0% of subjects had a Class I molar relationship, 13.0% had a Class II, 8.0% had a Class III malocclusion, and 4.0% could not be grouped because of molar extractions and different molar relationships on the right and left sides.
