Incidence of Trismus in Transalveolar Extraction of Lower Third Molar.

Background: Conventional mandibular third molar removal produces tissue trauma that induces an inflammatory reaction, leading to postoperative sequelae, the most common ones being trismus which influences the patient's quality of life in the postoperative period. Identifying the factors determining trismus after mandibular third molar extraction helps us to evaluate and correlate the incidence of trismus with morphological and surgical factors that are associated with its incidence in the postoperative period.

Methodology: Patients referred to our institution for surgical removal of their impacted lower third molar between November 2014 and February 2015 were the participants of the study.

Incidence of Risk and Complications Associated with Orthodontic Therapeutic Extraction.

Background: Extraction in orthodontics are carried out in the cases where there is space deficiency to align the teeth. The elective extraction of first or second premolars has been discussed in the literature for more than 50 years. In the 1940s and 1950s Nance, Dewel and Carey reviewed this as a useful option, and in the 1970s Logan and other leading orthodontists favoured the extraction as choice.
