Background & Aim: Different and contradictory results are concluded in studies conducted about the effect of different antiseptic solutions on post surgery infection rate and pain intensity. So, this study was performed to compare Betadine and normal saline in reducing complications after the surgical removal of impacted third molars in dental socket irrigation.
Methods & Materials: The study was performed experimentally. A group of 42 patients, referring to Tehran Milad Hospital dental unit and a private clinic, were selected sequentially for the purpose. The impacted third molars were extracted by means of a clinical indication. One side of the socket was irrigated with Betadine solution when the opposite side was irrigated with normal saline, comparing the infection rate and other post - surgical complications at two sides. Quantitative variables such as age and number of the sutures along with qualitative variables such as gender, pain, swelling, infection, dry socket and etc, were assessed. Statistical software of SPSS for windows was used for data analysis, using student t - test for quantitative and chi - square test for qualitative variables as statistical tests in order to compare the sides.
Results: The age of the patients was 24.3+7.8 years, 13 individuals (31%) were males while the next 29 individuals (69%) were females. There was no statistically significant difference between two sides irrigated with normal saline and betadine considering intensity of pain, swelling, infection and dry socket.
Conclusion: The study reveated no significant difference between number of sutures used in both sides, verifying the correctness of the study. No significant difference between all factors at both sides resulted in this study had been reported in other studies. Complications such as allergy, stimulation, mucosal redness, itching, subsequent sense of heat and possible burning associated with the use of betadine suggests the use of normal saline in minor teeth and oral surgery for irrigation.
