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

Overview

Pain after periodontal surgical procedures is a common manifestation. The perception of pain is highly subjective and varies substantially among individuals. Many factors affect pain perception, such as the nature, duration, and extent of the surgery and psychological aspects (e.g., stress and anxiety). Pain after periodontal surgery is an example of acute dental pain of mild to moderate severity. Non-steroidal anti-inflammatory drugs (NSAIDs) have a significant advantage in the control of pain after periodontal or oral surgical procedures.

Diclofenac is a powerful anti-inflammatory and analgesic drug that is well suited for local use in the oral cavity. Diclofenac competes with arachidonic acid in a dose dependent manner for binding with platelet COX. This results in decreased production of PG and thus reduces inflammation, swelling and pain.

As Diclofenac associated with many adverse effects, like gastric irritability, nausea, headache, dizziness. Undesirable effects may be minimized by using the lowest effective dose for the shortest duration necessary to control symptoms. As many of clinical trials have suggested Diclofeanc 50 mg alleviates the postoperative pain. So main aim of the study was to evaluate the effectiveness of low dose Diclofenac(25mg) in reducing the post operative pain after periodontal flap surgeries. Thus comparing the effects of low dose Diclofenac and Diclofenac 50mg for reducing post-operative pain.

Detailed Description

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.

Interventions

  • Drug: low dose diclofenac
    • it is a split mouth design in which one side recieved low dose diclofenac(25mg) after periodontal flap surgery and in next week second side will recieve diclofenac 50mg after flap surgery.

Arms, Groups and Cohorts

  • Experimental: study group one side
    • All patients were scheduled for open flap debridement surgery on at least two quadrants ≥1 weeks apart.One group will receive Low Dose Diclofenac tablets (25mg Diclofeanc and 325 mg paracetamol), BID for 3 days. The patients who are diagnosed with generalized moderate/severe chronic periodontitis will be included in study. For each quadrant, a flap was raised under local anesthesia (2% lignocaine with 1:80,000 epinephrine). In both the quadrants same technique of anesthesia will be employed. The location and the extent of surgery, volume of the local anesthesia given, and time required to perform the surgical procedure will be recorded in the patient file. Patients will be instructed to complete a pain diary chart for 3 days.
  • Placebo Comparator: study group second side
    • Other group will receive Diclofeanc (50mg Diclofenac and 325mg paracetamol), BID for 3 days. The patients who are diagnosed with generalized moderate/severe chronic periodontitis were included in study. For each quadrant, aperiodontal flap was raised under local anesthesia (2% lignocaine with 1:80,000 epinephrine). In both the quadrants same technique of anesthesia will be employed. The location and the extent of surgery, volume of the local anesthesia given, and time required to perform the surgical procedure was recorded in the patient file. Patients were instructed to complete a pain diary chart for 3 days.
