INTRODUCTION Many reciprocating file systems (RFs) have recently been introduced. This article reviews the properties, effectiveness, and clinical outcomes of the RFs. METHODS A PubMed electronic search was conducted by using appropriate key words to identify investigations on RFs. After retrieving the full-text relevant articles, the cross citations were also identified. RESULTS This revie...

Objective: To compare the root canal preparation of primary teeth with reciprocating and rotary NiTi instruments. Material Methods: Electronic databases (PubMed/MEDLINE, Web Science, TRIP, Lilacs, Embase, Scopus) were systematically searched until October 2020. In vitro studies comparing cleaning ability, debris extrusion, file deformation, or working time instruments in evaluated. Two reviewer...

In conventional endodontic treatment, alkaline solutions of sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) are used in combination to disinfect the root canal system and to eliminate debris and smear layers. An important concept that has emerged over recent years is the use of active physical methods for agitating these fluids to improve their penetration within areas th...

PURPOSE To report a case of primary conjunctival epithelial inclusion cyst with atypical manifestation. METHODS A 66-year-old woman presented with a yellowish, subconjunctival mass extending from the corneal limbus to the medial canthus in the left eye. Clinical, radiological and histological assays were performed. RESULTS The mass was well-delineated, and the overlying conjunctiva was norm...

The goal of root canal treatment is to prevent and treat apical periodontitis, by eliminating inflamed pulp tissue as well microorganism necrotic chemomechanical debridement providing a good quality filling. According Sjögren, et al. [1] the success rate goes high 96% in teeth without periapical lesions. Salehrabi, Rotstein [2] metanalyses, found 97% retention treated while Hannahan, Eleazer [3...

introduction: this study aimed to compare the efficacy of mtad, glyde and edta in removing the post-preparation smear layer and debris produced in apical third of curved molar root canals. materials and methods: forty extracted human maxillary first molars with curved mesiobuccal canals (30˚-35˚), similar root lengths and morphologies were divided into 3 experimental groups (n=12) and one contr...
