Summary

Wisdom teeth in the lower jaw are frequently buried in bone and must be taken out surgically. To reach the tooth, the surgeon lifts the gum away from the bone as a flap, and the shape of that flap is left to the surgeon's judgement. Two outlines are in everyday use. The first runs only along the necks of the teeth, so the gum is lifted without any additional cut. The second adds a short downward cut in front, which opens the field more widely but also divides some of the small vessels that run within the gum.

Because the tissues around a wound rely on a rich network of tiny vessels while they repair themselves, it is worth knowing whether these two outlines leave the local circulation in a different state. This project measured that circulation directly. A laser probe was placed against the tooth in front of the extraction site and against three points on the cheek-side gum, and the amount of moving blood beneath the probe was recorded. To make sure the probe returned to exactly the same spots at every visit, a thin clear plastic guide with prepared openings was made for each participant from a plaster model of the mouth.

Measurements were taken before the operation and again on the third and the seventh day afterwards. Facial swelling and how widely the mouth could be opened were recorded on the same occasions. Participants were assigned to one of the two flap outlines in turn, and every operation was carried out by the same surgeon so that the comparison depended on the flap outline alone.

  • Surgical Flaps
  • Oral Surgical Procedures
  • Regional Blood Flow
  • Tooth, Impacted
  • Molar, Third

Interventions

PROCEDURE

Sulcular flap elevation for wisdom tooth removal

The mucoperiosteum is raised through an incision confined to the gingival sulcus, carried from the mesial aspect of the first molar back to the distal aspect of the second molar and then along the external oblique ridge.

PROCEDURE

Three-cornered flap elevation for wisdom tooth removal

The same sulcular and posterior incision is used, with the addition of a vertical relieving cut placed anterior to the second molar and kept clear of the interdental papilla
