Background:The efficacy of a nonsteroidal anti-inflammatory agent, ketorolac tromethamine, was evaluated in pain control after periodontal surgery. This type of agent acts peripherally by inhibiting the release of prostaglandins and minimizing the local inflammatory response. Thus, there may be an advantage in pretreatment administration of ketorolac tromethamine, 10 mg, compared with placebo on operative pain during periodontal surgery.Materials and Methods:Two groups of 40 outpatients from the Department of Periodontology, Darshan Dental College and Hospital, Udaipur, were selected for this study. Patients who were to undergo periodontal surgery were randomly given either one group 10 mg ketorolac immediately before surgery or the other group placebo tablets at least 30 minutes before administration of local anesthesia (LA). All procedures were performed under LA, and the total volume of anesthetic used was recorded. The duration of surgery from the time of incision to the placement of the last suture was recorded. At the completion of the surgery, patients were supplied with printed record forms and were asked to rate their subjective operative pain intensity using a visual analog scale.Statistical analysis:The data were analyzed using the student t test.Results:Results indicated that preoperative treatment with ketorolac significantly reduced initial pain intensity of operative pain as compared with placebo. No adverse reactions related to preoperative medication were observed.Conclusions:The results of this study showed that 10-mg ketorolac administered immediately before periodontal surgery was effective for alleviating the operative painful sequelae.

Aim:The present study is undertaken to examine the film thickness of three most commonly used luting cements and to determine their usage as a luting agent. Materials and methods:This study was carried out strictly according to the guidelines of American Dental Association (ADS) specification no. 8. Two glass slabs of 5 cm in length and 2 cm in width were used. One glass slab was kept over the other glass slab and the space between the two glass slabs was measured using metallurgical microscope at the power of 10×. Two brands of glass ionomer cement (GIC) and one dualcured resin cement were used in this study. The test cement is sandwiched between two glass slabs. A static load of 15 kg was applied using universal testing machine on the glass slabs for 1 hour and the space present between the two glass slabs was measured using metallurgical microscope at the power of 10×.Results: Greatest film thickness was found in group III (Paracore) followed by group II (micron) and lowest in group I (GC luting and lining cement). All the tested samples can be used for luting purposes. Conclusion:Greatest film thickness was observed in Paracore followed by micron and lowest in GC luting and lining cement. This suggests that the 25 to 27°C is ideal for mixing of the cement when used for luting consistency. The cement with film thickness more than 30 µm should never be used for luting purposes.Clinical significance: The dentist should choose the luting cement with utmost care noting the film thickness and bond strength of the cement. The cement with low exothermic heat production and good bond strength should be encouraged.
