Pulpal disease, specifically dental pulpitis, is triggered by exogeneous stimuli from cariogenic bacteria or traumatic injury. The specific host defense in the dental pulp is regulated by the innate and adaptive immunity, of which the pulp-dentin complex odontoblasts play an essential role in the early stage of the dental immune response. It has been reported that the NLRP3 inflammasome is expr...

A routine eye examination of a 69-year-old man revealed a scleral perforation of one of the haptics of the anterior chamber intraocular lens (AC IOL) which had been implanted many years ago. The patient was asymptomatic with good visual acuity. His history was negative for any trauma, eye rubbing, topical corticosteroid use, or autoimmune disease. The horizontal and vertical white-to-white diam...

taurodontism is a rare dental anomaly in which the involved tooth has an enlarged and elongated body and pulp chamber with apical displacement of the pulpal floor. endodontic treatment of these teeth is challenging, because it is hard to identify the number of root canals. in this article a case of bilateral involvement of maxillary first molars is presented. endodontic treatment of right maxil...

Purpose: To report two patients with spontaneous scleral perforation and bleb formation associated with Marfan syndrome (MFS); which one of them also showed bilateral optic nerve dural ectasia. Case reports: An 11-year-old girl was referred with progressive myopia. Past medical history was negative. Slit-lamp examination revealed bilateral scleral thinning and perforation with bleb formation, s...

Studies have shown the cariostatic effect of Er,Cr:YSGG (2.78 mm) laser irradiation on human enamel and have suggested its use on caries prevention. However there are still no reports on the intrapulpal temperature increase during enamel irradiation using parameters for caries prevention. The aim of this in vitro study was to evaluate the temperature variation in the pulp chamber during human e...

The purpose of this study was to evaluate the use of artificial teeth for endodontic teaching. A questionnaire was prepared and submitted to 18 professors of Endodontics from different Brazilian universities to evaluate the following features of five cloudy resin artificial teeth: internal and external anatomy; coronal chambers regarding their size, shape and canal path; root canal regarding th...

OBJECTIVE In this article, the authors report on an in vivo study in which they assessed the validity of two commonly used cold pulp tests (carbon dioxide [CO(2)]and 1,1,1,2-tetrafluoroethane) and an electrical pulp tester (EPT) in determining pulp vitality by using direct inspection of the pulp as the reference standard. METHODS One hundred fifty patients undergoing endodontic therapy at the...

Presence of extra roots and canals should be considered before initiation of root canal treatment for the success of endodontic treatment. A mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%. This case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...

The aim of this study was to observe the histopathological pulp response following direct pulp capping of mechanically exposed teeth in rats with a composite of beta-tricalcium phosphate-hydroxyapatite bioceramic (BC) and poly (glycolic)-poly (lactic acid) (PLGA) material or a calcium hydroxide [Ca(OH)2] material, compared to BC alone and a negative control of water. Pulp of the maxillary molar...
