| Summary: | <p><span class="fontstyle0"><strong>ABSTRACT</strong></span></p><p><strong><span class="fontstyle0">Background: </span></strong><span class="fontstyle2">Mandibular third molar (M3M) is the most posterior of the three molars present in each quadrant. Racial variation, genetic inheritance etc can affect the jaw size, size of tooth and ultimately the eruption state of M3M. So, studies of impacted M3Ms have been carried out in various populations. But data relating to these are not evident from most of the parts of Nepal. Hence, this study was done to assess the status of impacted M3Ms in a tertiary care center in eastern Nepal. </span></p><p><span class="fontstyle0"><strong>Materials & Methods</strong>: </span><span class="fontstyle2">Total of 220 patients’ M3Ms (i.e 440 sites of M3Ms) were assessed with Panoramic Radiographs, in Department of Oral Medicine and Radiology. The impaction status was divided as class of impaction (I, II, III), level of eruption (A, B, C) and angulation (mesioangular, vertical, distoangular and horizontal). Data were entered in Microsoft excel sheet and analyzed using SPSS software version 11.5. </span><span class="fontstyle0">Results: </span><span class="fontstyle2">Class II impaction state was<br />most commonly present in this population group, in 345 sites (85.18%) while none of the patients had class III impaction. Level A eruption was most prevalent, 315 sites (77.78%). The least prevalent was level C eruption, 14 sites (3.46%). Majority 18 sites (46.67%) had vertical inclination while only 32 sites (7.9%) had horizontal inclination. </span></p><p><strong><span class="fontstyle0">Conclusion: </span></strong><span class="fontstyle2">The most prevalent impaction state of M3M in this population<br />group is Class II, Level A with vertical angulation. </span></p><p><strong><span class="fontstyle0">Keywords: </span></strong><span class="fontstyle2">impacted teeth; mandible; panoramic radiography; third molar.</span> <br /><br /></p> |
