Abstract:

Objective: The aim in this study was to investigate preoperative coagulation values of patients undergoing oral surgery under local anesthesia. Material and Method: The study included 1598 patients who presented to the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry at Adıyaman University between 2017 and 2018 for various reasons and underwent surgery under local anesthesia based on examination. The patients’ age and gender as well as their coagulation values such as activated partial thromboplastin time (APTT), prothrombin time (PT) and international normalized ratio (INR) were recorded and analyzed statistically. Results: The age range of the patients included in the study ranged between 11 and 92, and their mean age was 30.51 ± 11.09. Of these patients, 63.06% (n = 1007) were female, and 36.94% (n = 591) were male. The total number of female patients admitted was more than that of the male patients in terms of the distribution by gender. When the number of patients admitted were examined in terms of age groups (0–20, 21–40, 41–60, > 60), statistically significant differences were found especially between the ages 0–20 and 21–40 in both gender (p <0.05). No significant differences were found in groups over the age of 40 (p > 0.05). Values outside the normal range were observed in all of the coagulation values examined. Among these, APTT and PT (%) values that were lower than the normal and INR and PT (s) values that were higher than the normal were found to prevail. An examination of these abnormal values in terms of gender revealed that the values other than PT (%) were found to be statistically significantly higher in women, compared to men. In terms of age groups, these abnormal values belonging to the four coagulation parameters were found to be statistically significantly the highest among the people who were 21–40 years old (p < 0.001). Conclusion: Taking preoperative coagulation tests prior to locally applied surgical procedures is especially important in patients for whom detailed medical history cannot be obtained.
