fa THE PREVALENCE OF BILATERAL THREE-ROOTED MANDIBULAR FIRST MOLAR IN INDIAN POPULATION اندودانتیکس Endodontics پژوهشي Research <p> <strong>Introduction:</strong></p><p>  The purpose of the present study was to evaluate the prevalence of bilateral three-rooted mandibular first and second molars in Indian population. </p><p> <strong>Materials and Methods:</strong></p><p>  A total of 215 patients were screened bilaterally for mandibular first and second molar and 430 samples of periapical radiographs were obtained. The gender, symmetry, and prevalence of three-rooted mandibular first and second molars were recorded. The correlation between left and right side occurrences and distribution were recorded and analysed using Z-test. </p><p> <strong>Results</strong>:</p><p>  The results showed that 33 teeth had three-rooted mandibular first molars, 16 male and 17 female (P=0.442). Overall, 21 teeth of right jaw and 12 teeth of left jaw (P=0.103) showed presence of an extra-root. The prevalence of three-rooted mandibular first molars was 7.67% and second molar was 0.23%. The bilateral frequency distribution was 3.72% for the first molar. There was no statistically significant difference between right side and left side mandibular molars. Also, gender did not show a significant relationship with this variant. <strong></strong></p><p> <strong>Conclusion:</strong></p><p>  The endodontic treatments of first mandibular molars require a careful clinical approach in Indian population as a high racial prevalence of 7.67% three-rooted molars was found. However, in the same population, 0.23% mandibular second molars had three roots. </p><hr><p></p><p> <strong>Source: </strong>Iranian Endodontic Journal </p><p><a href="http://journals.sbmu.ac.ir/index.php/iej/article/view/2956" target="_blank"><font color="#0000ff"> Full Text</font></a></p> Endodontic; Mandibular; Molars; Root canal; Three-Rooted 0 0 http://idai.ir/browse.php?a_code=A-10-32-2081&slc_lang=fa&sid=1 Rupali Karale drkarale79@rediffmail.com 10031947532846009748 10031947532846009748 Yes Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Champa Chikkamallaiah 10031947532846009749 10031947532846009749 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Jayshree Hegde 10031947532846009750 10031947532846009750 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Srirekha Aswathanarayana 10031947532846009751 10031947532846009751 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Lekha Santhosh 10031947532846009752 10031947532846009752 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Kusum Bashetty 10031947532846009753 10031947532846009753 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Shwetha Rajanna Susheela 10031947532846009754 10031947532846009754 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India Srinivas Panchajanya 10031947532846009755 10031947532846009755 No Department of Conservative Dentistry and Endodontics, Oxford Dental College, Bommahalli, Bangalore, India
