Purpose. The aim of the present study was to evaluate the clinical response of the pulp in teeth with chronic periodontitis.Methods.\r\nConsecutive patients who had been admitted to the Clinics of Periodontology and fulfilled the criteria of inclusion were enrolled\r\nfrom January to December 2007. Ninety-eight single-root teeth from 27 patients with chronic periodontitis were evaluated clinically\r\nwith regard to clinical attachment level (CAL), probing depth (PD), and gingival recession (REC). After periodontal measurements,\r\nPulpal Sensitivity (PS) was evaluated with the use of a cooling stimulus test. Data was analyzed with Studentâ��s t test and\r\ncontingency C coefficient. Results. Teeth that responded positively to PS test presented lower values of CAL (7.8 �± 2.8 mm), PD\r\n(5.0 �± 2.3 mm), and REC (2.8 �± 1.8mm) in comparison to those that responded negatively (CAL = 12.0 �± 2.2 mm; PD = 7.9 �±\r\n1.6 mm; REC = 4.1 �± 2.4mm) (P < 0.01, Studentâ��s t test). In addition, significant correlations were observed between PS and\r\nperiodontal parameters. Conclusions. Within the limits of this study, it could be suggested that the progression of periodontitis\r\nmay significantly influence the negative pulpal response.
