OBJECTIVES To assess the fracture resistance of endodontically treated teeth with a novel Zirconia (Zr) nano-particle filler containing bulk fill resin composite. METHODS Forty-five freshly extracted maxillary central incisors were endodontically treated using conventional step back preparation and warm lateral condensation filling. Post space preparation was performed using drills compatible...

Background: The aim of this study was to determine and compare the fracture resistance of endodontically treated teeth restored with two different glass fiber posts. Materials and methods: Thirty extracted intact human premolar teeth were selected for the study. All the teeth were decoronated maintaining root length of 15mm from apex. Root canals were enlarged using protaper rotary file. Obtura...

This paper investigates some mechanical aspects of a new endodontic restoration technique, based on the idea that the root cavity can be more efficiently filled if multiple prefabricated composite posts (PCP) are employed. Multi-post technique increases bearing capacity and durability of endodontically treated teeth, as shown by numerical simulations performed through three-dimensional elastic ...

Objective The aim of this study was to evaluate and compare the 5-year survival and complication rate of metal-ceramic (MC) and composite single crowns performed within Public Dental Service, general dentistry, in three Swedish counties and with patients' gender, tooth position, root canal treatment and the presence of a post-and-core taken into account. Methods Data were collected from dental ...

INTRODUCTION Maxillary canine-first premolar transposition (Mx.C.P1) is an uncommon dental positional anomaly that may create many orthodontic problems from both esthetic and functional points of view. OBJECTIVE In this report we show the orthodontic management of a case of Mx.C.P1 associated with bilateral maxillary lateral incisor agenesis and unilateral mandibular second premolar agenesis ...

STATEMENT OF PROBLEM Teeth are weakened after endodontic treatment and should, ideally, be crowned, especially posterior teeth. However, this is not always possible. Information about the longevity of endodontically treated teeth without crown coverage may assist in selecting appropriate treatment modalities. PURPOSE The aims of this cohort study were to evaluate the survival rate for endodon...

INTRODUCTION The objectives of this investigation were to compare the initial cephalometric characteristics of complete Class II Division 1 malocclusions treated with 2 or 4 premolar extractions and to verify their influence on the occlusal success rate of these treatment protocols. METHODS A sample of 98 records from patients with complete Class II Division 1 malocclusion was divided into 2 ...

BACKGROUND Few dentists have seen an impacted mandibular canine and first premolar, and there is little information in the literature on the treatment of this rare condition. CASE REPORT A 13-year-old Japanese male with an impacted mandibular right canine and first premolar was treated orthodontically. We discuss both the surgical and orthodontic options and present the successful orthodontic...
