Aim: As the patterns of impaction can affect the treatment plan of removing or remaining the
impacted tooth, the difficulty of surgery, and the post-surgical complications, this survey aimed for
assessment of the mandibular wisdom tooth impaction patterns in terms of angulation and depth
in the north population of Iran.
Materials and Methods: 196 Panoramic radiographs were gathered from patients attending
to the department of oral and maxillofacial surgery of GUMS in 2018-2019. To perform this
retrospective study the prevalence of impaction, angulation, and the level of the eruption were
assessed. The data were analyzed by SPSS 16.
Results: This study found that the most common pattern of impacted mandibular third molars
was level B in terms of depth and mesioangular in terms of angulation.
Conclusion: The current study notes the importance of determining the angulation and level of
wisdom tooth in designing the pre-surgical treatment and in post-surgical complaints.
Keywords: Impacted teeth; Panoramic radiography; Retrospective study; Third molar.

mities P<0.05. In addition There were statistical
differences in the satisfaction of four domains of the questionnaire (oral function, facial aesthetics,
psychological, and social aspects), between QOL of patients that had correction of the deformity
and the non-operated patients with same kind of deformities. This indicated that quality of life was
significantly higher in patients operated on by orthognathic surgery (P<0.001). Results showed
statistical differences between groups and suggested that people with no deformity (normal) and
those subjected to orthognathic surgery have a better quality of life compared to those with a facial
deformity and experiencing a QOL that is near normal.
Conclusion: Dentofacial correction by orthognathic surgery seems to have a positive effect on
the quality of life and it is an effective method in normalization of the social and psychological
state.
Keywords: Orthognathic surgery; Dentofacial deformities; Quality of life.
