Brief Summary

Periapical lesions are the commonly occurring pathologic lesions that affect the periradicular tissues of the tooth.This lesion can be classified as granuloma, cystic, or abscess .The pathological changes seen in some periradicular and periapical cases are due to the presence of microorganisms, and their byproducts.These released toxins have the ability to diffuse through inflamed pulpal tissue and get into the periapical area. In a necrotic pulp, the lack of blood flow in the root prevents host immunity from eliminating the infection.

Outcome Measures

Primary Outcomes (1)

  • Treatment of Postoperative Pain

    Patients will be evaluated for postoperative pain via (NRS) to record the intensity of pain.as follows: 0 reading represents "no pain" ; 1- 3 reading represents "mild pain" ; 4- 6 reading represents "moderate pain" and 7- 10 reading represents "severe pain".

    from 0 hours to 2 weeks after the procedure

Secondary Outcomes (1)

  • Periapical Healing

    After 6 months to 12 months

Study Arms (2)

Metapaste Calcium Hydroxide

ACTIVE COMPARATOR

About 13 healthy patients of both genders presented with periapical radiolucency will subject to complete preparation of the root canal system using the (Metapaste Calcium Hydroxide(Pre-mixed paste) as an intracanal medicament.

Other: Metapaste Calcium Hydroxide

Bio C-Temp

ACTIVE COMPARATOR

About 13 healthy patients of both genders presented with periapical radiolucency will subject to complete preparation of the root canal system using the (Bio C-Temp) as an intracanal medicament.

Other: Bio C-Temp

Interventions

To compare the effect of calcium hydroxide and Bio-C Temp as intra canal medications on postoperative pain via VAS and periapical healing via CBCT
