Periapical Lesions

After administration of LA and rubber dam isolation, acess cavity will be prepared using carbide burs in high speed hand piece with copious irrigation. Working length will be determined using root ZX apex locator and will be verified radiographically. Canal preparation will be done with protaper rotary instruments in which Sx to S2 will be used to shape the canals and F1 and F2 will be used to finish until the apex. 5ml of 5.25% NaOCl will be used as irrigant after each instrument. After instrumentation , the canals will be irrigated with 5.0 ml of 17% EDTA for 1minute followed by irrigation with 5.0 ml of 5.25% NaOCl. Canals will be dried with absorbent paper points, filled with calcium hydroxide paste and access cavity will be restored with IRM. Patients will be recalled after 1 week.At the next appointment, after paste removal, copious irrigation with 5.25% NaOCl will be done and canals will be dried with paper points. Canals will be obturated with Gutta-Percha and ZOE based sealer.

Influence of Glycemic Levels on Healing of Periapical Lesions in Type 2 Diabetic Patients Following Primary Nonsurgical Root Canal Therapy

Absence of signs and symptoms Absence of tenderness to percussion Tooth mobility of grade 1 or less Absence of associated soft tissue swelling or tenderness to palpation Attachment loss of less than 5mm .
Two experienced observers with no knowledge of the treatment protocol will independently examine the immediate post obturation and follow up radiographs, mounted side by side, under controlled conditions. The treatment is considered successful only when both clinical and radiographic criteria are met. The worst outcome of an individual root decide the overall outcome for the tooth. In the event of disagreement, the two observers will meet to discuss their findings and came to an agreement.

Absence of periapical alterations (radiolucency at furcal or periapical region) Scoring of each tooth will be done according to the following five point scale (PAI)
Score Description
Normal Periapical structure
Small changes in bone structure
Changes in bone structure with some mineral loss
Periodontitis with well defined radiolucent area
Severe periodontitis with exacerbating feature
Lesions with a PAI score < 2 was considered
