Dentigerous cysts are one of the most prevalent types of odontogenic cysts and are associated with the crown of an unerupted tooth, especially of the mandibular third molar. In this study, the characteristics of a dentigerous cyst developed around a mandibular third molar on panoramic radiographs were investigated. The panoramic images of 257 consecutive dentigerous cyst cases associated with a mandibular third molar were analyzed. The mean age of the patients was 45.9 ± 13.3 years. The size of the cyst did not significantly correlate to the age of the patient. The unilocular type (89.1%) and the crown side type (68.5%) were significant. The associated mandibular third molars had a high frequency of class III (64.6%) and position B (48.3%) in Pell and Gregory classification and of horizontal position (36.3%) in angulation. Dentigerous cysts were thought to originate and grow commonly around deeply impacted third molars. The associated third molar with dentigerous cyst tends to have a mesial inclination. Dentigerous cysts do not appear to develop gradually after the crown formation has finished, but arise at various periods randomly.

Dentigerous cyst is an odontogenic cyst that surrounds the crown of an impacted tooth, caused by fluid accumulation between the reduced enamel epithelium and the enamel surface, usually associated with mandibular third molars. The purpose of this study was to find out the prevalence of dentigerous cyst caused by impaction of mandibular third molar at the oral and maxillofacial surgery department of Hasan Sadikin hospital Bandung. This study was a descriptive survey study. Samples were taken from the data of patient’s medical record from July 2006 until June 2011. The result of this study showed the number of oromaxillofacial cyst cases in the period was as much as 316 (0.78%). Dentigerous cyst was the most common odontogenic cyst (48,64%). Dentigerous cyst most commonly caused by impaction of the mandibular third molar (13,89%). The amount of male and female patients with dentigerous cyst was the same (50% each). The most age group that suffered dentigerous cyst due to impaction of the mandibular third molars was the age group of 41-50 years (40%). The most chosen therapy was enucleation (100%). From the results of this study can be concluded that dentigerous cyst due to impaction of mandibular third molars was the most common case, with the same frequency found in both male and female, the most age group of impacted was the age group of 41-50 years old, and the most chosen therapy was enucleation.

<p><strong>Aim</strong>: 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.</p><p><strong>Methods</strong>: 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.</p><p><strong>Results</strong>: 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 <em>p </em>value is 0.043 0.048 respectively.</p><p><strong>Conclusion</strong>: 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. </p>
