Evaluation of Root Migration Distance After Coronectomy of Impacted Third Molars

Not Applicable

Completed

• Conditions: Impacted Tooth With Abnormal Positioning
• Interventions: Procedure: coronectomy

• Registration Number: NCT06620718
• Lead Sponsor: Mustafa Kemal University

Brief Summary

The aims of this study were to investigate postoperative pain, edema, and trismus after coronectomy procedure, to assess the risk of endodontic lesion formation at sixth month, and to determine relationship of the root migration distance with age.

Detailed Description

The roots of impacted lower third molars may be associated with the inferior alveolar nerve (IAN). To mitigate this risk and reduce trauma to the patient, a conservative approach involving the removal of the problematic crown portion and leaving the root may be adopted.

This clinical study was conducted between 2021-2022 years and was accordance with the Helsinki Declaration of 1975, as revised 2013. All subjects were informed about the study and clinical procedures and provided written consent The study included 73 patients aged between 18-55 years. These patients were divided into two age groups: The first group, consisting of patients aged 18-30. The second group, consisting of patients aged 31-55.

The coronectomy was surgically performed. Postoperative pain, swelling, and interincisal distance were evaluated based on age. Pain was assessed using a 10 cm Visual Analog Scale (VAS) with patients providing ratings before the operation and on the 3rd and 7th postoperative days. The progresion of endodontic lesion was evaluated in 6 months after coronectomy.

The distance of root migration achieved at 6 months after coronectomy was measured by independent examiner. Calibrated panoramic radiographs were used to determine the level of migration.

The statistical analysis of the data obtained in our study was performed using SPSS software The needed statistical analyses were used for comparison of the data. The Levene test was used for comparison of the root migration distances in the age groups. The significance level was set at 0.05.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 73

Inclusion Criteria

• The study focused on applying coronectomy, a more conservative approach, instead of extraction for mandibular third molars associated with the inferior alveolar nerve that were indicated for prosthetic, orthodontic, prophylactic purposes, or those causing pericoronitis

  • Systemically health,
  • To maintain ideal oral hygiene,
  • Absence of caries, pulpal and endodontic lesions in the impacted third molar indicated for extraction
  • No known allergies to any antibiotics, or no use or history of bisphosphonate medication
  • No use of tobacco or any illicit drugs by the patient.
  • Not being pregnant

Exclusion Criteria

• Other conditions unlike abovementioned items.

Arm && Interventions

Group	Intervention	Description
Evaluation of root migration at sixth month after coronectomy	coronectomy	Seventy three patients were divided into two age groups: The first group, consisting of patients aged 18-30, included 17 males and 23 females. The second group, consisting of patients aged 31-55, included 17 males and 16 females

Primary Outcome Measures

Name	Time	Method
the mesaurement of root migration distance	six months after coronectomy procedure	the distance from the enamel-cement line of the adjacent tooth to the remaining root or roots after coronectomy.

Secondary Outcome Measures

Name	Time	Method
the percentage of edema	postoperatively 3rd and 7th day after coronectomy	percentage of edema was measured extraorally
the measurement of the distance of interincisal opening	postoperatively 3rd and 7th day after coronectomy	maximum interincisal distance was measured using a calliper during the maximum opening of the mouth
the pain assessment	postoperatively 3rd and 7th day after coronectomy	A 10 cm or 100 mm-Visual Analogue Scale was used for assessment. The findings suggested that 100-mm VAS ratings of 0 to 4 mm can be considered no pain; 5 to 44 mm, mild pain; 45 to 74 mm, moderate pain; and 75 to 100 mm, severe pain.
