Cemento-Ossifying Fibroid Epulis in the Posterior Maxilla.

Cemento-ossifying fibroma is a benign fibro-osseous lesion arising from the periodontal ligament and has the potential to form cementum and bone in the periodontal ligament. Cemento-ossifying fibroma is a painless, pedunculated, or sessile, smooth exophytic growth arising attached to the gingival tissues. We present a case of cemento-ossifying fibroid epulis in the posterior maxilla attached to the interdental gingiva between the 26 and 27 region buccally in a 52-year-old female patient managed with surgical excision of the lesion, extraction of the involved teeth, curettage, and palatal obturator while under general anesthesia.

Tooth discoloration and internal bleaching after the use of ledermix paste with various bleaching agents - An study.

Background: To assess the reversal of discolouration caused by Ledermix using various bleaching agents.

Material And Methods: Twenty six extracted human mandibular premolars were taken and divided into four groups. Six teeth were divided into three each which are taken as positive and negative controls.

Fracture resistance of tooth restored with four glass fiber post systems of varying surface geometries-An in vitro study.

Background: The purpose of this study was to relate the fracture resistance of endodontically treated teeth in relation to post geometry.

Material And Methods: Forty single rooted mandibular premolars were instrumented by step - back technique and obturated by lateral condensation. Forty teeth were randomly divided into four groups: Reforpost glass fiber X-ray®, RelyX®, Exacto conical® and Parapost Fiber Lux®.

Evaluation of manual and two-rotary niti retreatment systems in removing gutta-percha obturated with two root canal sealers.

Objective. The objective of this study was to evaluate the efficacy of two retreatment NiTi systems (protaper universal retreatment files, R-Endo), when compared to manual technique in removing Gutta-percha obturated with two sealers. Study Design.
