<p>&nbsp;<b style="text-align: justify;"><span lang="EN-IN" style="font-size:12.0pt;&#10;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Objective</span></b><span lang="EN-IN" style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">: To compare digital Intra Oral Periapical (IOPA) Radiographs&nbsp; with Cone Beam CT (CBCT) images&nbsp; in detecting and localizing alveolar bone loss by comparing linear measurements of&nbsp; height, depth and width of the defects to analyse if use of CBCT is justified for assessing periodontal defects.</span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%;mso-layout-grid-align:none;text-autospace:none"><b><span lang="EN-IN" style="font-size:12.0pt;&#10;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Materials and method: </span></b><span lang="EN-IN" style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">35 CBCT images and digital IOPAs &nbsp;&nbsp;from the secondary database were assessed for horizontal and vertical bone loss&nbsp; using measurement tool and contrast enhancement &nbsp;features of the software.<o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%;mso-layout-grid-align:none;text-autospace:none"><b><span lang="EN-IN" style="font-size:12.0pt;&#10;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Result</span></b><span lang="EN-IN" style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">: No significant difference&nbsp; was seen between the two imaging methods in terms of identification of pattern of bone loss, depth and width of defect..&nbsp; 21of the 35 teeth evaluated had combined bone defects which could be detected only on CBCT.<o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%;mso-layout-grid-align:none;text-autospace:none"><b><span lang="EN-IN" style="font-size:12.0pt;&#10;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Conclusion</span></b><span lang="EN-IN" style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">: The two methods were similar in detecting height, depth and width of bone defects. CBCT however allowed analysis of&nbsp; buccal and lingual/palatal surfaces&nbsp; improving visualization of the morphology of the defect. Hence, CBCT should be only advised for advanced periodontitis.<o:p></o:p></span></p> <p class="MsoNormal" style="text-align:justify;line-height:200%"><span lang="EN-IN" style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">&nbsp;</span></p>
