Background: The etiology of mandibular third molar impaction is proposed to be mainly due to inadequate space between the distal of the second mandibular molar and the anterior border of the ramus of the mandible. This study was aimed to assess whether an association exists between different facial types and mandibular length to impaction of mandibular third molars. Materials and Methods: The study consisted of 170 patients who were assessed for facial type clinically based on facial index and mandibular length radiographically on lateral cephalogram. The impaction status was determined clinically and radiographically on orthopantomogram. The facial type was categorized as euryprosopic (broad face), mesoprosopic (normal facial type), leptoprosopic (long face), hypereuryprosopic (extra broad face), and hyperleptoprosopic (extra long face). Results: Of 170 patients, 18.8% of cases were with hypereuryprosopic profile, 33.5% of cases with euryprosopic profile, 24.7% with mesoprosopic profile, 21.8% with leptoprosopic, and 1.2% with hyperleptoprosopic profile were found. Nearly 42.2% of cases with hypereuryprosopic profile, 52.6% of cases with euryprosopic profile, 53.6% cases of mesoprosopic profile, and 60.3% cases of hyperleptoprosopic and leptoprosopic profile had impacted mandibular third molars. As for mandibular length assessment, 66% cases of short mandibular length, 64.5% cases of normal mandibular length, and 27.9% cases of long mandibular length had impaction. Conclusion: Within the limitations of the study, it was concluded that, though a higher incidence of impacted third molar was noted in patients with long facial pattern, no significant difference could be established among facial types and their association with impacted mandibular third molars. A significant association was noted between mandibular length and impaction.

Pseudoaneurysms are rare lesions secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery. They are usually produced by arterial breach leading to extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. This sac gradually expands and can be damaged. Nonsurgical interventions are the treatment of choice for pseudoaneurysms. In the case reported here, emergent endovascular injection of acrylic glue was successful in the treatment of a pseudoaneurysm from a branch of the internal maxillary artery secondary to surgical extraction of impacted maxillary third molar.

Background: Facemasks are recommended to control the COVID-19 pandemic transmission. This study was conducted with a purpose to investigate the knowledge, attitude and practices among general population regarding the usage of facemask during COVID-19 pandemic to limit the spread of the corona virus disease.Methods: A cross sectional study was conducted through Google forms. Questionnaire consisted of 7, 3 and 5 questions on knowledge, attitude and practices respectively. Questionnaire was shared on social media. Score of 1 was assigned to correct response and score of 0 for incorrect response, thus making a maximum score of 7 for a subject. Accordingly, score was <3 depicts individual had poor knowledge. 3-5 and >5 had good and excellent knowledge respectively.Results: Out of total 500 participants, we had 242 (48.4%) males and 258 (51.6%) females. The age of participants ranged from 20 to 60 years. Majority of participants (25.2%) were from Kerala State. Almost 97.6% reported that it was necessary to wear mask in current situation. The overall mean knowledge score was 5. The mean knowledge score was higher among females (5.07%) as compared to males (4.93%) and the difference was statistically significant. When they were asked if they know the correct steps of wearing a mask, almost 82.5% reported “yes” but while asking for coverage of mask on face only 75% were aware of it correctly.Conclusions: The overall knowledge of our study population was good. The knowledge was excellent for the age group of 20–30 and post-graduates.
