Effect of Age, Gender, Side and Impaction Types on Surgical Difficulty During Mandibular Third Molar Extraction.

Abstract

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.

Transalveolar Extractions in Different Age Groups

“…This is mainly due to the advantage of right handed surgeons, which makes it easy to retract cheek and elevate the tooth while extracting. 25 . X axis represents age, Y axis represents tooth number.This bar graph depicts that transalveolar extractions were prevalent in the age group 31-40 years,and the tooth involved in this age group was found to be lower third molar teeth( 38 purple in color and 48 dark green in color).…”

Postoperative Complications of Impacted Mandibular Third Molar Extraction Related to Patient’s Age and Surgical Difficulty Level: A Cross-Sectional Retrospective Study

“…Furthermore, old age is accompanied by the activity of osteochondral cells and their progenitors in addition to weaker defense against foreign organisms, thereby being more susceptible to infections due to the lymphoid tissue changes including T cells that eventually will influence the antibodies' production [10,11]. Finally, compared to young patients, old patients have denser bone and more complete root development in addition to a higher probability of ankylosing spondylitis as to why old patients need a longer duration of bone removal during the surgery [12].…”
