Abstract
Objective: The purpose of this study was to compare the incidence
of complications between surgical removal of third molar and
germectomy, objectively and subjectively.
Material and Methods: A prospective nonrandomized study for all
patients who were undergoing minor oral surgery of mandibular third
molar was carried out in the Oral & Maxillofacial Department (OMF) of
Sultan Abdul Halim Hospital, Malaysia (HSAH). The indication for surgery
was for orthodontic reasons. The patients were divided into three groups
according to their radiographic root morphology, namely Group I (root not
formed), Group II (root partially formed), and Group III (roots fully formed)
Results: A total of 44 patients were enrolled into this study;
2 teeth from each patient, henceforth involving 88 teeth. There
was a statistically significant difference in the age between the
three groups (p < 0.05). Germectomy was the shortest procedure.
In the objective evaluation conducted 1 week post-surgery, no sign
of trismus and facial swelling was observed in these three groups.
In the subjective evaluation, we found there were significant
differences in patients’ ability to tolerate orally (p < 0.05) and
ability to perform daily activities (p < 0.05) among the three
groups.
Conclusion: This study shows low incidence of complications in all the
three groups. Germectomy is a simple and safe procedure; thus, this
prompted the author advocate the early removal of mandibular third
molar.

molar-is it safe?

Introduction
Te mandibular third molar, which is the lower
wisdom tooth, has the highest rate of impaction
as compared to all the teeth, primarily due to
the lack of alveolar arch space between the ante-
rior border of ramus and the distal surface of the
second molar.

Surgical removal of mandibular
third molar, including germectomy for orthodontic
purposes, is one of the most common procedures
in our facility. Germectomy is a procedure of
removing a tooth that has formed one-third or less
of its root and has a radiographically discernible
periodontal ligament.

Early removal of these teeth is widely
acknowledged, as allegedly many studies have
demonstrated a direct correlation between age
and the incidence of complications.

However,
there is still lack of clinical evidence in texts,
whereby the duration of the procedure and
postoperative sequelae between germectomy and
surgical removal of third molar were compared for
further analysis. Te purpose of this study was to
compare the incidence of complications in relation
to germectomy, early removal of third molar and
surgical removal of third molar, objectively as well
as subjectively.
Material and methods
For the purpose this study, a prospective
non-randomized study for all patients undergoing
minor oral surgery of mandibular third molar was
carried out in Oral and Maxillofacial Department
(OMF), Sultan Abdul Halim Hospital(HSAH), from
April to September 2014. Te patients were divided
into three groups according to their radiographic
root morphology: Group I (roots not formed),
Group II (roots partially formed) and Group III
(roots fully formed) figures 1-3. Te study had
followed the tenets of the Helsinki Declaration on
medical protocol and ethics for research
involving human subjects and informed consent
was obtained from all participants and approved
by the National Ethical Committee (Medical
Research and Ethics Committee). Tis research
did not receive any specifc grant from funding
agencies in the public, commercial, or not-for-
proft sectors. To be included in the study
sample, all patients aged between 14 and 23
years must have bilateral mandibular third
molar. Te patients are excluded from the study if
they have a history of acute peri-coronitis;
pregnancy; underlying medical illnesses such as
metabolic disorder, cardiac problems
