ABSTRACT:
Various Risk factors initiate Submucous fibrosis which may be augmented by NSAIDs. A number of animal studies on their mechanism indirectly support it especially regarding alterations in prostaglandin synthesis. This study has been designed to find association of these drugs with Oral Submucous fibrosis in the presence of risk factors. Newly diagnosed patients of Oral Sub mucous fibrosis were recruited for this study who attended Dental Department of Karachi Medical and Dental College from July 1 till Dec 31,2013.A structured interview and medical record of each patient was used to determine the demographic profile, any addiction, previous and present illnesses and drug (s) used. Through examination of Oral cavity was carried out to access the severity of disease as per modified Khanna & Andrade Classification (1995). Statistical Analysis was done by SPSS 15. Total 102 patients were recruited from dental OPD as per criteria of inclusion. Among these patients 36 (49.31%) were using NSAIDs in which Acetaminophen (30.55%), Acetylsalicylic acid (25.00%) and Diclophenac (19.44%) were 1st, 2nd and 3rd most common drugs. Data shows that 14 patients (28.88%) had mild and 22(61.11%) had sever fibrosis which was significantly high (P<0.05). Mild fibrosis was seen in 05 (45.46%) and Sever fibrosis in 06 (54.54%) out of total 11 patients who were using NSAIDSs since less than or equal to 6 months. Similarly mild fibrosis was seen in 09 (36.00%) and Sever fibrosis in 16 (64.00%) out of total 25 patients who were on NSAIDs since more than 6 months. No statistical significant difference (P>0.05) in severity of fibrosis is seen in patients who were using NSAIDs since less than or equal to 6 months but statistical significant difference (P<0.05) in severity of fibrosis is seen in patients who on these drugs since more than 6 months. Addiction burden was calculated by Average Duration x Average Frequency, which was 92.72 for Pan, 88.88 for Supari and 61.30 for Miscellaneous. No statistically significant difference (P>0.05) was seen in addiction burden of various substances in these patients. An association of NSAIDs with Oral Sub mucous fibrosis exists. The pathology is augmented if these drugs are used in the presence of risk factors. Therefore these drugs should not be prescribed to these patients until a clear benefit is not targeted.
