Are impacted third molars always necessary to be removed?
The asymptomatic impactions with small potential risk for development of pathologies must be periodically followed up. However the author agreed that most of impacted teeth associated with a pathological condition must be surgically extracted to prevent future and more severe problems.
What is impacted lower third molar?
Abstract. Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth.
What is the most common impaction in mandibular 3rd molars?
Data analysis showed that impacted third molars were 1.9 times more likely to occur in the mandible than in the maxilla (P =0.000). The most common angulation of impaction in the mandible was mesioangular impaction (48.3%) and the most common angulation of impaction in the maxilla was the vertical (45.3%).
What is the lower third molar?
The lower third molar region corresponds to an anatomical region located in reference to the lower third molar, as such, it is found in the posterior zone of the oral cavity, between the lower molars and the mandibular ramus, extending medially to the floor of the oral cavity, and laterally up to the oral vestibule.
When Should 3rd molars be removed?
The American Association of Oral and Maxillofacial Surgeons states that “about 85% of third molars will eventually need to be removed.”10(p3) The association recommends extraction of all 4 third molars by young adulthood—preferably in adolescence, before the roots are fully formed—to minimize complications such as …

What is the primary reason for the removal of mandibular third molars?
Of 516 participants with follow-up data, 200 (39%) had 720 third molars extracted, and their main reasons for removal were availability of dental insurance (88%), tooth not likely to erupt (78%), and dentist’s recommendation (21%).
What happens after third molar extraction?
The initial recovery and healing from wisdom tooth extraction usually occurs over about three to five days. It is normal to have slight bleeding (oozing) from the site considering the surgical procedure performed. The minor bleeding (oozing) after extraction should start to ease after the first 24 hours.
What happens if impacted tooth is not removed?
Gum disease Along with tooth decay, the difficulty of cleaning impacted, partially erupted wisdom teeth increases the risk of developing a painful, inflammatory gum condition called pericoronitis. This can lead to pain and swelling in or around the tooth, jaw or cheeks, and will likely continue to recur if not treated.
Can a third molar be displaced during extraction?
Displacement of maxillary and mandibular third molars during extraction is a rare but potentially serious complication that can be managed either immediately or delayed, depending on the clinical situation.
How are teeth displaced in the maxillary sinus?

How to determine superior displacement of tooth 1-8?

Can a tooth be displaced at the time of surgery?
Teeth Displaced: Teeth at the Time of Surgery. Inadvertent displacement of teeth or fragments of teeth beyond the tooth socket during extraction is an uncommon occurrence. In this paper, we present two cases of displacement of impacted third molars, one maxillary and one mandibular.
