AIM: This study aims to evaluate the effectiveness of intra-articular injection chondroitin sulfate and sodium hyaluronate in cases temporomandibular joint (TMJ) degenerative osteoarthritis. MATERIAL AND METHODS: Thirty patients ASA I both sexes, who were selected from outpatient clinic Oral Surgery Department, Faculty Dentistry – Suez Canal University, complaining painful TMJ, presence unilate...

The aim of this study was to compare the accuracy of the Radiovisiography (RVG) with conventional Radiographic in canal length estimation in vitro for root canal treatment. Forty-single-rooted teeth were endodontically assessed and working lengths were determined using both conventional intra-oral dental film and Radiovisiography (RVG) 1R1X 70 intra-oral x-ray system. Measurement assessment was...

Currently calcium hydroxide is often used as an intra-canal medication during root canal treatment. It has a pH of approximately 12.5, and it has antimicrobial activity, tissue-dissolving ability, inhibits tooth resorption and induces repair by hard tissue formation. It has been promoted for intra-canal placement for various endodontic conditions, including apexification, apexogenesis, after tr...

Background. The aim of this study was to compare the push-out bond strengths of calcium silicate-based ProRoot MTA and Biodentine cements and SureFil SDR and EverX Posterior bulk-fill composite resins. Methods. Twenty-four single-rooted maxillary central incisors were sectioned below the cementoenamel junction, and the root canals were instrumented using rotary files. Thereafter, a parallel pos...

removal of smear layer and disinfection of canals are important objectives of teeth root canal cleaning. in order to achieve this purpose, rinsing substances, intra canal drugs as well as ultrasound are used. today, use of laser to remove smear layer and to disinfect root canals has increasingly attracted the attentions. till now different lasers such as co2, nd:yag, er:yag, er,cr:ysgg have bee...

AIM To monitor ex vivo intra-canal irrigation with three endodontic needles (25, 27 and 30 gauge) and compare them in terms of irrigant flow rate, intra-barrel pressure, duration of irrigation and volume of irrigant delivered. METHODOLOGY A testing system was constructed to allow measurement of selected variables with pressure and displacement transducers during ex vivo intra-canal irrigation...

OBJECTIVE To compare the consistency rates of pre- and intra-operative radiological findings in patients with chronic suppurative otitis media (CSOM). METHODS In a cross-sectional study, 80 patients with CSOM underwent pre-operative CT scanning and we compared the results with intra-operative clinical findings during mastoidectomy from 2000-2004 in the Otology Department, Amiralmomenin Hospit...

microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. the use of mechanical debridement, chemical irrigation or other antimicrobial protocols and intra-canal medicaments are critical to attain this goal. the aim of this ...

The purpose of this study was to compare regional bond strength at middle and cervical thirds of the root canal among glass fiber-reinforced composite (FRC) endodontic posts luted with different cements, using the push-out test. To compare the performance (retention) of two types of luting cements polycarboxylat cement and Glass ionomer cement used to cement translucent fibre post. and To compa...
