Description of intervention(s) / exposure
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

Diagnosis / Prognosis
Comparator / control treatment
Total-etch (3M ESPE Adper Single bond plus Adhesive) was applied on the other tooth as a comparator treatment. All the restorations were performed on the same day without any break by single qualified dentist in the Department of Operative dentistry, Rawal Institute of Health Sciences (RIHS), Islamabad.
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.
Total etch requires multiple bottles and involves etching, rinsing and application of primer and bond. Total etch system requires removal of smear layer which is thought to be responsible for causing post- operative hypersensitivity but universal adhesive system involves in the modification of smear layer; thence, is responsible for less hypersensitivity as claimed by their manufacture. Moreover, Universal bond application is a single step procedure which consumes lesser time.
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. Cavity was prepared by bur and then Total etch adhesive was applied in the following way: 37% Phosphoric acid was applied for 25 seconds on the prepared cavity. The acid was then washed by air and water pressure through triple syringe for 20 seconds. Then 2 coats of primer + bond were applied by rubbing through micro brush for 40 seconds. When the surface became shiny, it was light cured for 20 seconds. After application of bond, the composite material was applied in increments of 1-2 mm layer thickness in both cases (Universal adhesive as well as on Total-etch technique). Curing each increment was done for 20 second.
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 30 to 40 minutes
Quantity of adhesive applied was 2 drops of adhesive from the bottle per tooth

Outcomes
Primary outcome [1] 331620 0
Post- Operative hypersensitivity on VAS before applying universal bonding.

Timepoint [1] 331620 0
immediately after placement
(Post operative hypersensitivity on VAS is taken after three step /universal bond application and composite restoration)
Secondary outcome [1] 410557 0
post operative hypersensitivity on VAS after applying total etch bonding system
Timepoint [1] 410557 0
24 hours after placement
(Post operative hypersensitivity on VAS is taken 24 hours after completing the composite restoration i.e. the next day)

Summary
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.
