Evaluation of Guided Endodontic Microsurgery and Two Different Retrograde Filling Materials

Suez Canal University24 enrolled

Overview

The aim of this study was to evaluate the effect of guided endodontic microsurgical root end resection on bone healing compared to nonguided microsurgery using two different retrograde filling material (Well root putty, MTA) by cone-beam computed tomography.

Inclusion Criteria: * Tooth is restorable pocket depth is less than 4mm and mobility in its normal limit ( less than 1mm) * Persisting or emerging disease following root-canal treatment when root canal re-treatment is inappropriate. * Tooth with acceptable endodontic treatment and have a new post and crown restoration, but have a persistent or enlarging periapical lesion ( size less than 10 mm) * Obstructed canal (the obstruction proved not to be removable, by passed and the risk of damage was too great). * Extruded material or instrument with clinical or radiological findings of apical periodontitis and/or symptoms are present. Exclusion Criteria: * Non restorable tooth * Contraindicating medical condition ( severe systemic condition and psychological condition) * Anatomical contra indication * Poor general oral status and supporting periodontal tissue.

Outcomes

Primary Outcomes

Operating time

The operating time was measured from the beginning of osteotomy to the end of retrograde filling procedure

Time frame: perioperative

Secondary Outcomes

Change in bone density measurement over time

Time frame: 1 week, 6 months

Pain "Numerical Rating Scale (NRS)"

Pain was categorized into four categorical scores: (1) none \[score 0\], (2) mild \[score from 1-3\], (3) moderate \[score from 4-6\], (4) severe \[score from 7-10

Time frame: first day , 1 week

Change in Linear measurements over time

The evaluator located the slice on CBCT that will appear to demonstrate the largest size of the lesion and made a measurement of the lesion at what appeared to be the widest dimension. A second measurement of the widest dimension will be then made at 90 degrees to this initial measurement. These measurements will be made from a bone landmark to another bone landmark. These measurements will be performed in two planes for each lesion.

Time frame: baseline and 6 months

Bone healing assessment

For analysis of periapical radiographic healing, CBCT scans were oriented in the buccolingual plane along the longitudinal axis of the treated roots. The observers rated the radiographic healing based on the parameters described recently by von Arx et al. (2016) in. Healing was categorized and scored as follows: 1. Fully healed (score 2) , Partially healed (score 1) and Not healed (score 0)

Time frame: baseline and at 6 months

Change in volumetric measurement over time

Time frame: 1 week, 6 months
