Aim: To study the effect of age, gender, side and impaction types on surgical difficulty during mandibular third molar extraction through the data collected over a period of one year by single maxillofacial surgeon. All the extractions were performed under the same environment and conditions.Methods: Descriptive clinical study of 401 patients was carried out between the ages of 16 to 45years. Age, gender, impaction side and impaction types (according to the winter classification) were recorded on proforma. Duration of surgery for each patient was recorded after starting incision to the completion of suture which was divided into less than 10 minutes (mild), 11 to 20 minutes (moderate) and above 21 minutes (severe). Pearson’s Chi-square test was used for data analysis and significance level was less than or equal to 0.05.Results: Among 401 participants, 225 (56.1%) were male and 176 (43.9%) were female. Mean age was 31.5 years and mean operation time was 17.59 minutes. After statistical analysis there was a significant correlation among gender and side of impaction where p value is 0.043 0.048 respectively.Conclusion: There is a statistically significant correlation between gender and side of impaction with duration of surgery which is considered as the objective measure of surgical difficulty whereas age and impaction types didn’t show any significant correlation.

“…Gender is one of the predictors of difficulty of impacted third molar surgery. 17,19 There is a statistically significance relation between gender and surgical duration which was also noted in the study undertaken by Susarla and Dodson 16 and Sundus AM, Maha MA, Khawlah TH,Ahmed SA. 19 However many studies are not in favor of this.…”

Introduction: This study was conducted to assess the relationship of patient's age, gender, side and impaction types to surgical difficulty during mandibular third molar extraction through the data collected over a period of one year by single maxillofacial surgeon. All the extractions were performed under the same environment and conditions. Methods: Descriptive clinical study of 401 patients was carried out between the ages of 16 to 45 years.Age, gender, impaction side and impaction types (according to the Winter classification) were recorded on proforma. Duration of surgery for each patient was recorded after starting incision to the completion of suture which was divided into less than 10 minutes (mild), 11 to 20 minutes (moderate) and above 21 minutes (severe). Pearson's Chi-square test was used for data analysis and significance level was less than or equal to 0.05. Results:Among 401 participants, 225 (56.1%) were male and 176 (43.9%) were female. Mean age was 31.5 years and mean operation time was 17.59 minutes. After statistical analysis there was a significant correlation among gender and side of impaction where p value is 0.043 and 0.048 respectively. Conclusions:There is a statistically significant correlation between gender and side of impaction with duration of surgery which is considered as the objective measure of surgical difficulty whereas age and impaction types didn't show any significant correlation. v e r t i c a l , h o r i z o n t a l , m e s i o a n g u l a r a n d distoangular. 10,13 Most of the authors believe that there is a relation between surgical difficulty and radiographic factors such as type and depth of impaction and number of roots 2,9,12,13 but the correlation between patient factors and surgical duration is still a controversy. 2,6,7,9 Removal of the impacted teeth is more difficult with advancing age. 1 Younger patients will have relatively soft and more resilient bone whereas older patients will have stiff and harder bone. Bone removal in older patients during surgery require more time and amount of bone removal is also more, resulting in Keywords RESULTSThe total of 500 patients were referred for impacted third molar extraction during the study period. Only 401 patients were fit to be enrolled in the study. DISCUSSIONThe present study compared the effects of age, gender, side and angulation of impacted tooth to the operative difficulty which was measured in terms of duration of extraction of impacted tooth as more the duration, more difficult will be extraction. A number of studies have used surgical technic and surgical time as determinants of difficulty. 8,11,16,18 Clinical as well as radiological findings prior to the surgery will help to correctly plan the surgery and Original Article Mandibular third molar extraction; Bhuju K G et al. Side of impaction of third molar tooth also has statistical significant correlation with surgical duration. This is mainly due to the advantage of right handed surgeon, which makes it easy to retract cheek and elevate the to...

“…[1] There are some classification methods for determining surgical difficulty in the literature. Pederson proposed a difficulty index for the removal of mandibular third molars, [2,4,7] and Pederson scale scores are based on local anatomy and radiographs, [2,10] while the modified Parant scale is used to estimate surgical difficulty postoperatively based on the surgical conditions. [2] Previous studies in the literature have set out to identify factors associated with postoperative pain, swelling, and trismus.…”

Background: The objective of the study was to investigate the effect of surgical difficulty detected using the Pederson and Parant scales and the duration of the surgery on postoperative pain, swelling, and trismus. Methods: Surgical difficulty for each mandibular third molar was estimated using the Pederson and Parant scales and the duration of the surgery in 50 healthy patients. Postoperative pain, swelling, and trismus were evaluated preoperatively and on the 2nd and 7th days post-operation and the recorded data was analyzed with statistical significance set at P = 0.05. Results: Age was found to be a risk factor for 7th day postoperative pain (p = 0.032) and trismus (p = 0.008). The relationship between the duration of surgery and the Parant scale was statistically significant (p = 0.000), and the duration of surgery was found to be a risk factor for 7th day postoperative trismus (p = 0.017). Conclusion: There were no significant relationships between the postoperative complications and the Pederson and Parant scale scores.
