The records of 350 patients with 379 extractions were examined to analyze possible relationships between postoperative complications following third molar extraction and parameters such as age, sex, position of the molar, surgical technique and postoperative care.
Younger patients tend to suffer more often from complications.
Surgery performed in female patients was also resulted in more complications after third molar extractions. There were more complications when the position of the third molar was more aberrant. A single impacted tooth is more common in the permanent dentition and the teeth usually involved are the mandible third molar and the maxillary cuspids. A discrepancy between tooth size and jaw size is probably the result of a combination of both genetic and environmental factors. The dental arches must undergo considerable anteroposterior growth to accommodate all permanent molars because the mandible third molar tends to erupt relatively late and slowly, disturbances associated with its eruption and position, pericoronitis and impaction, easily arise in the second and third decades of life.
