Scaling and root planing has always been considered an indispensable procedure in periodontal disease management. As a result of instrumentation, dentinal tubules become exposed and sensitivity develops. Besides causing discomfort, the condition may deter a person from establishing or maintaining adequate oral hygiene procedures, further complicating oral health. Although materials have been tested to alleviate post-operative dentinal hypersensitivity, the issue has not been comprehensively addressed in the literature. Moreover, very few 'in office' topical medicaments available for dentine hypersensitivity meet the requirements of the ideal desensitising agent. In view of the ongoing search for an ideal desensitiser, this article evaluates the clinical efficacy of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) and HEMA-G (aqueous solution of hydroxyethyl methacrylate and glutaraldehyde) desensitisers in managing dentine hypersensitivity following scaling and root planing.
Study design: Forty-eight patients undergoing periodontal treatment were included in the study. These patients presented with hypersensitivity following phase I therapy. After taking the baseline scores, agents were applied and reductions in post-operative dentine hypersensitivity were evaluated using the verbal rating scale at 0, 1, 4, 10 and 28 days. The results were analysed by percentage reduction in hypersensitivity and showed statistically significant differences between the control and treated teeth.
Results: Significant decreases were recorded for all the three test stimuli for group I (CPP-ACP) and group II (HEMA-G). Control group patients demonstrated a statistically non-significant (P > 0.05) decrease in mean discomfort score, observed from day 0 to day 4, which subsequently became significant on day 10. A highly significant (P < 0.0001) decrease was observed at day 28 for all the test stimuli, indicating that patients within the control group were also experiencing relief.
Conclusion: The study concluded that subgingival scaling and root planing followed by single application of CPP-ACP or HEMA-G provided higher short-term reductions in dentine hypersensitivity compared with controls.
