Review of flap design influence on the of the health of the periodontium after mandibular third molar sugery

The purpose of this study is to review the effect of flap design in terms ofperiodontal status of the preceding second molar after lower thrd molar surgery.Impacted lower third molar surgery may result in periodontal complications on the distal surface of the adjacent second molar.Flap design that is used during impacted third molar surgery is important to prevent those complications. Several different flap techniques, mainly envelope, triangular (vertical) flaps, and theirmodifications have been developed to minimize those complications. Each technique has some advantages as well as disadvantages. It is also reported that the selection of the type of flap used for lowerthird molar sugery on the periodontal status of the second molas, as well as the factors that may influence this outcome, has been uncertain. The decision to use on one or the other of the flaps shouldbe based on surgeon´s preference ( Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2007; 104:18-23)

Third molars are the teeth that are most commonly impacted. They are present in 90% of thepopulation with 33% having at least impacted third molar.
These impactions are probably the result of both genetic and environmental factors.
The removal of impacted third molar is often advovated forvariety of reason, however, absolute indications and contraindications for the removal of these teeth have not been established. While there is little controversy over removal of the impacted thirdmolar associated with pathologic lesions, questions still remain about theprophylactic removal of these teeth . At the recent National Institutes of Health Consensus Development Conference on Removalof Third Molars is was agreed that impaction or malposition of a third molar was an abnormal state and might justify is removal such treatment was not considered to be “prophylactic” and thus...
