GONDIM, Candice Regadas et al. Prevalence of impacted teeth in panoramic radiographs. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2010, vol.10, n.3, pp. 085-090. ISSN 1808-5210.

AIMS: To evaluate which groups had most impacted teeth in relation to gender and age. MATERIAL AND METHODS: We conducted a retrospective, cross-sectional study, analyzing 3,500 panoramic radiographs. The patients, aged from 15 to 35 years, of both genders, all had complete permanent dentition, and the radiographs showed at least one impacted tooth. A previously prepared form was used for the collection of data, which were descriptively analyzed with measurements showing the main trends in means, standard deviation, maximum and minimum values and inferential statistics using the chi-square test, adopting a significance level of 0.05 (p=0.05) in all cases. RESULTS: The group of molars showed the highest means (2.81). No statistically significant differences (p=0.825) were found between gender and presence of the impacted tooth. There was a statistically significant difference (p=0.001) between age and presence of an impacted tooth, which was most prevalent among patients aged 15 to 20 years. CONCLUSIONS: The molars were found to be the most impacted group of teeth. Females had more impacted teeth than males, but the difference was not statistically significant. The most prevalent age group was 15 to 20 years.
