Deep neck infection after third molar extraction.

Odontogenic and oropharyngeal infections are relatively common in the cervicofacial region. In rare cases, odontogenic or peritonsillar abscesses may spread through the deep fascial cervical spaces and cause life-threatening complications. Odontogenic infection is the most common cause of deep neck infections and it accounts for 43% of the cases.

Difficulty of impacted mandibular third molar tooth removal: predictive ability of senior surgeons and residents.

Purpose: The present study investigated whether residents are able to estimate the degree of difficulty of mandibular third molar removal to the same extent as senior surgeons.

Materials And Methods: The study included 2 residents and 2 senior surgeons, each of whom extracted 50 mandibular third molars of similar complexity. The clinical variables evaluated included patient age, gender, body size, maximal mouth opening, and tongue interference.
