Abstract
Aims: To investigate the prevalence and pattern of impacted teeth in the sample of North-East China.
Study Design: Descriptive and Retrospective study.
Place and Duration of Study: School of Stomatology, Department of oral and maxillofacial surgery, Second Affiliated Dental Hospital of Jiamusi University Between Jun 2013 to October 2015.
Methodology: Orthopantomogram radiographs and clinical dental records are used to determine the impacted teeth in Five thousand seven hundred and eighty four randomly selected patients. All of 5784 patients were examined (3754 males, 2030 females), with an age range of 7-76 years and a mean age of 23±4 years. The minimum age for inclusion was 7 years. The data was entered into the computer and analyzed using the Statistical Package for Social Sciences (version 20. Inc. Chicago, USA). The Pearson’s Chi‑square was used to determine the differences in the distribution of impacted teeth between genders. The significant level was tested at the 5%.
Results: Out of 5784 patients, a total of 1342 (23.2%) presented an impacted tooth, 701 (52.2%) were male and 641(47.8%) were female. Among them, 1485 were the number of impacted teeth. The prevalence of impacted teeth was 23.2%; third molars were the most common (11.70%; n=677), followed by canines (5.55%; n=321), incisor and premolars (2.92%; n=169 and 2.82%; n=163). The impacted teeth were mostly seen in the age group between 17-26 years old (43.8%; n=774). No significant relationship between impacted teeth among the gender was found (p=0.22).
Conclusion: The prevalence of impacted teeth was 23.2% in this research and the patients aged between 17 to 26 years were most affected. The minimum age of 7 years must be an inclusion criteria study for to assess the real prevalence of incisor impaction.
