Molar Extraction

Iatrogenic mandible fracture is a rare complication of a tooth extraction with an incidence between 0.0033–0.0034%. This study retrospectively analyzes a total of 8 patients who underwent lower molar extraction associated with mandible fracture during tooth removal in the period from April 2006 to March 2019. The assessed parameters were age and sex of patients, method of tooth extraction, side distribution of fracture, type of extracted tooth, the position of a lower third molar, presence of bone pathological lesion formed in connection with a tooth, displacement of bone fragments, and sensory impairment in the innervation area of the mental nerve. The position and impaction of the lower third molars were evaluated according to Pell and Gregory’s classification and Winter’s classification. One fracture was left-sided, and 7 fractures were right-sided. In 6 cases, Winter’s extraction elevator was used. In 7 patients, the mandible fracture was treated surgically by performing stable osteosynthesis with the plates and screws. One patient was treated conservatively. This work analyzes the causes of iatrogenic mandible fractures and provides recommendations to reduce the risk of their occurrence.

Apical Tooth

A 2-year-old Holstein heifer presented to a university teaching hospital with an apical tooth infection of the right mandibular third molar. A standing oral extraction technique was attempted for tooth removal; however, the molar could not be delivered intact. A tooth sectioning technique was performed, and the affected molar was successfully delivered. Three months postextraction, the heifer had fully recovered, and the extraction site had healed. To the authors’ knowledge, this is the first description of a tooth extraction in a cow using a tooth sectioning technique. This case describes an alternative technique for tooth removal in cattle with an apical tooth infection. The clinical, diagnostic, and therapeutic features of this case may be helpful to clinicians when they approach similar cases in the future.

<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>
