Pattern of mandibular third molar impaction in patients attended the Hawler College of Dentistry: a retrospective radiographic study

Abstract

Background and objective: The aim of this study was to assess radiographically the angulations and depth of impacted mandibular third molars. Methods: In a retrospective study 163 impacted mandibular third molars of 100 patients were examined on orthopantomograms (OPT) in the College of Dentistry/ Hawler Medical University during 2008. From these orthopantomograms the angulations (mesioangular, distoangular, vertical, and horizontal) and the depth (types A, B, and C) of the impacted mandibular third molars were recorded. The frequencies of unilateral and bilateral impaction were also recorded. Results: The average age of the patients was 26.5 + 5 ranging from 20-40 years with a median of 25 years. Fifty eight (58%) of the cases were female and 42 (42%) were male. The frequency of mesioangular, distoangular, vertical and horizontal impactions were 73 (44.8%), 37 (22.6%), 28 (17.2%), and 25(15.4%) successively. The depths of the impactions were 45 (27.6%) depth A, 74 (45.4%) depth B, and 44 (27%) depth C.The frequency of unilateral impaction was 26 (26%) and that of bilateral impaction was 74 (74%). Conclusion: Impacted mandibular third molars are more common in female. Mesioangular impaction is more common followed by distoangular. Depth B most common and most of the patients have bilateral impaction.

A Retrospective Study on the Etiological Factors of Orofacial Pain in a Malaysian Sample

“…There was a statistically significant association between 25 and 34 years' age group and orofacial pain, which is in agreement with Pau et al 26 and Kurchid et al 27 Pain originated from dentoalveolar and supporting structures contributed to the highest numbers of patients with age group of 25 to 34 years old compared with other types of orofacial pain. Among this type of orofacial pain, pulpitis and pericoronitis are the commonest form of dental condition in this age group that cause patients to seek for a treatment.…”

“…Those findings are in contrast to study done by Smiljic et al 21 and Aggarwal et al 22 However, the present study showed that there was statistically no significant difference between genders in relation to orofacial pain, which is in line with Rikmasari et al 23 In addition, the number of females was more than males in pericoronitis which is similar to the studies performed by Yamalik and Bozkaya 24 and LeResche. 25 There was a statistically significant association between 25 and 34 years' age group and orofacial pain, which is in agreement with Pau et al 26 and Kurchid et al 27 Pain originated from dentoalveolar and supporting structures contributed to the highest numbers of patients with age group of 25 to 34 years old compared with other types of orofacial pain.
