Author: Shaddad, Mohamed A.; Ahmed, Anas A.; Abuaffan, Amal H.; Yousif, Yousif O.
Abstract: Objectives: The purpose of the present study was to assess the prevalence and pattern of impacted mandibular and maxillary third molars in a sample of Sudanese population. Methods: A descriptive cross-sectional study conducted in radiographic dental center covering the majority of Khartoum state. A total of 2600 orthopantomograms records were inspected and 576 cases were selected as per the inclusion criteria. Each Orthopantomogram was evaluated for the frequency and angulation of impaction according to Winter’s classification. Descriptive statistics, frequency, distribution, tables were used. Chi-square test was used for data analysis. The level of significance was set to be p≤ 0.05. Results: Mandibular impacted third molars were the most prevalent followed by maxillary molars 53.8% & 46.2% respectively, females were more affected 79.6% than males 20.4%. No significant difference between genders (p-value = 0.25). Mesioangular pattern was recorded as the highest pattern of third molar impaction 25.7% and was seen generally in the mandible 45% while vertical pattern was the most common in the maxilla 32.2%. Conclusion:The prevalence and pattern of impacted third molar recorded in this study occurred within the range reported in the literature, with early detection of impaction a better treatment can be planned and performed. The study provided some evidence about the extent of the problem, however a strong conclusion cannot be drawn since the sample is not representative to whole Sudanese population. Therefore, further studies are recommended with large sample size including different provinces of Sudan in order to induce a better conclusion.
