Following a clinical examination, the teeth were categorized into three groups based on the severity of stage II periodontitis: mild, moderate, and severe. The pulpal responses to EPT and CT were recorded and compared with those of a sound control tooth from the same patient. The Chi-square test, Fisher&#39;s exact test, Kruskal-Wallis test, Mann-Whitney test, and Bonferroni adjustment (alpha=0.05) were used to analyze the data. </span></span></span></span><br> <span style="line-height:150%"><span calibri=""><b><span new="" roman="" times=""><span style="color:black">Results: </span></span></b><span new="" roman="" times=""><span style="color:black">The severity of stage II periodontitis had a significant impact on the pulpal response to CT (P<0.001), and teeth with severe stage II periodontitis significantly exhibited more pulpitis compared to those with moderate stage II periodontitis (P<0.001) and mild stage II periodontitis (P<0.001). However, the severity of stage II periodontitis did not significantly affect the pulpal response to EPT (P=0.199). Gender did not significantly influence the pulpal response to either CT (P=0.151) or EPT (P=0.772).&nbsp;&nbsp;&nbsp; </span></span></span></span><br> <span style="line-height:150%"><span calibri=""><b><span new="" roman="" times=""><span style="color:black">Conclusions: </span></span></b><span new="" roman="" times=""><span style="color:black">The results of the present study indicate that the severity of stage II periodontitis significantly affects the pulpal response to CT, with teeth affected by severe stage II periodontitis exhibiting more pulpitis. However, the severity of stage II periodontitis did not significantly affect the pulpal response to EPT.&nbsp; </span></span></span></span></span><br> <br> &nbsp; 0 0 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-78&slc_lang=fa&sid=1 Reza Nazem 10031947532846001330 10031947532846001330 No Faculty of dentistry, Isf.c., Islamic Azad University, Isfahan, Iran Parisa Ranjbarian 10031947532846001331 10031947532846001331 Yes Department of Endodontics, Faculty of Dentistry, Isf.c., Islamic Azad university, Isfahan, Iran Ehsan Rafiei 10031947532846001332 10031947532846001332 No Department of Periodontics, Faculty of Dentistry, Isf.c., Islamic Azad University, Isfahan, Iran Zahra Mohammadi 10031947532846001333 10031947532846001333 No Department of Endodontics, Faculty of Dentistry, Isf.c., Islamic Azad university, Isfahan, Iran
