COMPARISON OF COMPOSITE RESIN AND RESIN MODIFIED GLASS IONOMER RESTORATIONS ON DENTINAL HYPERSENSITIVITY IN NON-CARIOUS CERVICAL LESIONS
Dentin Hypersensitivity (DH) is frequently encountered in teeth with Non Carious Cervical Lesions (NCCLs) and often requires restoration with an adhesive material. Although Resin Modified Glass Ionomer (RMGI) and Composite Resin (CR) are both effective in reducing pain of DH, the literature is equivocal regarding the best one for this purpose. The purpose of Present study was to compare the mean decrease in Numeric Pain Assessment Score (NPAS) of DH in NCCLs restored with CR versus RMGI. It was a randomized clinical trial conducted at Operative Dentistry Department, Lahore Medical and Dental College, Lahore. Total 100 patients aged 20 to 60 years with hypersensitive NCCLs were randomly allocated to CR or RMGI groups. Baseline and 24 hours post-operative NPAS were recorded and decrease in pain scores were calculated. Data was analysed in SPSS version 19.0 using independent sample t-test. The mean pain scores at baseline in CR and RMGI groups were 6.50±1.82 and 6.70 ± 1.69 respectively. At 24 hours both groups showed significant decrease in mean pain scores which were 3.20 ± 1.38 and 4.50±1.32 respectively. Independent sample t-test showed that the decrease in pain in CR was higher than RMGI and the difference was statistically significant (P value < 0.001). Conclusion: It was concluded that both materials were effective in reducing DH in NCCLs and CR was significantly more efficient than RMGI.
