Objectives
We investigated general dentists’ reasons for recommending
removal or retention of third molars and whether patients adhered to
dentists’ recommendations.
Methods
In a 2-year prospective cohort study (2009–2011) in the
Pacific Northwest, we followed 801 patients aged 16 to 22 years from 50
general dental practices. Generalized estimating equations logistic
regressions related patient and dentist characteristics to dentists’
recommendations to remove third molars and to patient adherence.
Results
General dentists recommended removal of 1683 third molars from 469
(59%) participants, mainly to prevent future problems (79%)
or because a third molar had an unfavorable orientation or was unlikely to
erupt (57%). Dentists recommended retention and monitoring of 1244
third molars from 366 (46%) participants, because it was too early
to decide (73%), eruption path was favorable (39%), or space
for eruption was sufficient (26%). When dentists recommended
removal, 55% of participants adhered to this recommendation during
follow-up, and the main reason was availability of insurance
(88%).
Conclusions
General dentists frequently recommended removal of third molars for
reasons not related to symptoms or pathology, but rather to prevent future
problems.
