To investigate the effect of chronic periodontitis on dental pulps by assessing histological changes in the pulps of teeth with moderate to severe periodontitis.
A total of 242 teeth from 162 patients with moderate to severe periodontitis were collected, and histological changes in pulps were investigated by staining with haematoxylin and eosin. Baseline data were taken from the patients’ records before extraction. The morphologic changes observed in the pulp were classified as degreeI, degree II, degree III, degree IV. Statistical analysis of the severity of periodontitis and histological changes with the pulps was applied to Mann–Whitney U rank sum test, while the contingency coefficient was used to analyze the interrelationship between the severity of periodontitis and histological changes in the pulps.
The interrelationship between the severity of periodontitis and histological changes in the pulps was 0.274 (P<0 .001="" and="" between="" differences="" em="" existed="" group="" moderate="" periodontitis="" severe="" significant="" teeth="" with="">P0>
There was a positive association between the severity of periodontitis and histological changes within the pulp. More attachment loss was correlated with pathological changes within the dental pulp.
