To Compare Efficacy of Low Dose Diclofenac (25mg) in Management of Postoperative Pain After Periodontal Flap Surgery

The present split mouth, single blind randomized controlled clinical trial was carried out in the

Department of Periodontology and source of the patients was from the outpatient section of Tatyasaheb Kore Dental College & Research Centre, New Pargaon.

Patients were enrolled in the study between November 2016 and June 2017. Based ' on the power of study that was l 80% with alpha of 0.05 with SD of ±1.47, we required

18 experimental quadrants and 18 control quadrants. Considering 10% dropout " sample size was finalized at 20.

The study included 20 patients [14 males and 6 females] with generalized chronic periodontitis.

With age ranging from 17-55 years, the selected patient had atleast 20 natural teeth, and with no history of previous periodontal therapy preceding six months of study. Medically compromised patients, pregnant and lactating mothers, smokers and alcoholics, and those with a history of taking anticoagulant therapy, patient reporting intake of steroidal or non-steroidal antiinflammatory drugs (previous 3 months) or antibiotics in previous six month were excluded from the study. Patient with known hypersensitivity to Diclofenac and gastric diseases were also not considered.

The protocol of the study was explained to each patient, and informed consent was obtained after explanation of the study. A split mouth design was used. A total of 40 quadrants in 20 patients (two quadrants in each patient) were operated. Complete medical evaluations of all the patients were done to rule out any systemic conditions.

All patients were scheduled for open flap debridement surgery on at least two quadrants >1 weeks apart. Each quadrant was randomly allocated (coin test) a different medication regimen for postoperative pain control. So in one patient two quadrant were operated one quadrant received Low Dose Diclofenac tablets (25mg Diclofenac and 325 mg paracetamol), BID for 3 days, whereas the other operated quadrant received Diclofenac (50mg Diclofenac and 325mg paracetamol), BID for 3 days.

A flap was raised under local anesthesia (2% lignocaine with 1:80,000 epinephrine). In both the quadrants same technique of anesthesia was employed. The location and the extent of surgery, volume of the local anesthesia given, and time required to perform the surgical procedure was noted in the patient file (Table/Fig 4). Participants were instructed to complete VAS chart once in the morning and once in evening for 3 days with the gap of 8 hours in between and recalled on 4thday and asked about any discomfort noted during following postoperative dayss in the form of questionnaire [Table/fig 5]. For measuring the clinical pain intensity the participants were provided with the visual analog scale (VAS). The VAS consists of a 10-cm line anchored by two extremes: no pain and pain that could not be more severe.

Participants were asked to make a mark on the line representing their level of perceived pain.

STATISTICAL ANALYSIS:- Data were analyzed using statistical software. The P value was set at 0.05 for all tests. The postsurgical pain parameters were presented as mean - SD and were compared using the independent t test.

While for the intra group analysis repeated measures of analysis of variance (ANOVA) test was used and data were presented as mean.
