Brief summary

Objective: To determine and compare the mean post-operative hypersensitivity of three step Total-etch technique and one step Universal bonding technique following composite restoration in two different teeth of the same patient. Design: A Randomized clinical trial Place and duration of study: Department of Operative dentistry, Rawal Institute of Health Sciences (RIHS), Islamabad from Jan 2019 to Jan 2020. Methodology: 100 patients were selected by consecutive sampling. Composite restorations were performed on two different teeth of the same patient by applying 3M ESPE Scotchbond Universal adhesive on one tooth and Total-etch (3M ESPE Adper Single bond plus Adhesive) on another tooth. The bonds and teeth were selected randomly. All the restorations were performed by single operator. Post-operative hypersensitivity (POH) was recorded by continuous visual analog scale (VAS of 0 – 10) before, immediately after and 24 hours after the placement of composite restoration using cold stimulus. Data was analyzed using SPSS version 20. Independent sample T test was applied. P-value < 0.05 was considered significant. Result: No significant association was found between POH of Total etch and Universal bond technique before (p-value= 0.7), immediately after (p-value= 0.87) and 24 hours after (p-value= 0.67) the restoration. Gender analysis showed significant association (p < 0.05) with Total etch adhesive i.e. before (p-value= 0.003), immediately after (p-value=0.04) and 24 hours after (p-value=0.001) the restoration. Males showed more hypersensitivity as compared to females’ restorations (p-value< 0.05). Insignificant association of hypersensitivity was found between males and females with Universal adhesive system at any time (p-value >0.05). Conclusion: No significant difference in POH was found between the two materials when a good sample size and proper technique was observed along with the removal of patients’ pain perception bias.

3M ESPE Scotchbond Universal adhesive system is a one step, single bottle, no mixing technique. It involves in the modification of smear layer; thence, is responsible for less hypersensitivity as claimed by their manufacturer. Current study aimed at determining whether there is any difference in post operative hypersensitivity felt by the patients between the Total etch and Universal adhesive system.

3M ESPE Scotchbond Universal adhesive system is a one step, single bottle, no mixing technique. It involves in the modification of smear layer; thence, is responsible for less hypersensitivity as claimed by their manufacturer. Current study aimed at determining whether there is any difference in post operative hypersensitivity felt by the patients between the Total etch and Universal adhesive system. All the restorations were performed and sensitivity were recorded by single operator (qualified dentist in post graduation training) in the department of Operative dentistry, Rawal Hospital. The two teeth were restored in the same clinic with no break in between. Post-operative hypersensitivity (POH) was recorded by continuous visual analog scale (VAS of 0 – 10) before, immediately after and 24 hours after the placement of composite restoration using cold stimulus. The hypersensitivity noted before the start of procedure was taken as a base line. The technique involved application of cold spray i.e. Tetrafluoroethane (TFE) on a small piece of cotton. This TFE soaked cotton was then applied on the mid facial surface of the tooth to measure hypersensitivity. The caries were removed by burs. After cavity preparation, Universal adhesive system was applied for 40 seconds by rubbing the entire preparation through micro brush. The surface was lightly air dried to remove the residual solvent. The second layer of adhesive was then reapplied and light cured for 20 seconds. Composite restoration was applied through incremental technique and light cured for 20 seconds. Sensitivity was recorded immediately after placement of restoration with composite. Finishing was performed after 24 hours with carbide finishing bur and polishing brush. The sensitivity was recorded again at this time. Duration for restoration was 20 to 30 minutes Quantity of adhesive applied was 2 drops of adhesive from the bottle per tooth
