Abstract

Background
This retrospective study aimed to evaluate vectoral alteration of impacted mandibular third molars (IMTMs) over time in patients
aged 15–32 years.
Materials and methods
Angulation values of the IMTMs of 87 patients were evaluated and compared using three different references at three different
time points. Angulation values of IMTMs for each reference point at each time interval were compared. Data were analyzed using
chi-squared test, Mann-Whitney U test, and Kruskal-Wallis test.
Results
A significant change (p < 0.05) in angulation over time (either increase or decrease) was observed in the measured IMTMs at all
three reference points. However, no significant result was found in terms of the direction of this change in any group.
Conclusion
The angle between the IMTM axis and different reference points may change over time. However, estimation of the magnitude or
direction of angular change does not seem to be possible.The decision to recommend extraction or retention of asymptomatic
IMTM should be made by considering the patient’s expectations, needs and the physician’s experience.
