the Relationship Between Various Clinical Variables and Surgical Difficulty of Patients Have Impacted Lower Third Molar

NCT05320744 | Unknown DMC

• 1 other identifier: impacted lower third molar
• Study Type: observational
• Target: 50
• Locations: 1 country
• Sites: 1

Brief Summary

This study is to evaluate the effect of angle of impaction, impaction depth, and bone density on surgical difficulty of impacted lower third molar, by measuring the angle of impaction, the depth of impaction (Winter's Red line), and bone density (gonial, and antegonial indices) preoperatively by using panoramic radiograph and to correlate the angle, the depth of impaction, and bone density with the surgical difficulty by operation time and surgical technique.

Conditions

Impacted Third Molar Tooth

Outcome Measures

Primary Outcomes (5)

• Angle of impaction

  is measured along the lamina dura of lower second and third molar by using Planmeca Romexis Software.

  preoperative

• Winter Red line

  is measured by drawing perpendicular line from amber line to the point of application of dental elevator by using Planmeca Romexis Software

  preoperative

• Gonial index

  is measurement of mandibular cortical thickness by using bisectrix the gonial angle by using Planmeca Romexis Software

  preoperative

• Antegonial angle

  is the measurement of the mandibular cortical thickness measured on the line perpendicular to the mandibular cortex at the intersection with the tangent line to the anterior border of the ramus by using Planmeca Romexis Software

  preoperative

• operative difficulty

  determined by the surgical techniques of the extraction and the duration of extraction according to Pernambuco difficulty scale

  intraoperative

Interventions

surgical extraction of impacted lower third molar PROCEDURE

surgical removal of impacted third molar under local anesthesia.
