Three-dimensional (3D) reconstruction of cone-beam computed tomography (CBCT) scans appears to be a valuable method for assessing pulp canal configuration. The aim of this report is to describe endodontic treatment of a mandibular second premolar with aberrant pulp canal morphology detected by CBCT and confirmed by 3D modeling. An accessory canal was suspected during endodontic treatment of the...

The aim of this study was the fabrication and evaluation of a novel bioactive and bactericidal material, which could have applications in dentistry by supporting tissue regeneration and killing oral bacteria. Our hypothesis was that a new scaffold for pulp-dentin tissue engineering with enhanced antibacterial activity could be obtained by associating extracellular matrix derived from porcine bl...

Injectable hydrogels have the great potential for clinical translation of dental pulp regeneration. A recently developed PEG-fibrinogen (PF) hydrogel, which comprises a bioactive fibrinogen backbone conjugated to polyethylene glycol (PEG) side chains, can be cross-linked after injection by photopolymerization. The objective of this study was to investigate the use of this hydrogel, which allows...

Denticles are small, tooth-like protrusions that are commonly found on the palate of early tetrapods. Despite their widespread taxonomic occurrence and similar external morphology to marginal teeth, it has not been rigorously tested whether denticles are structurally homologous to true teeth with features such as a pulp cavity, dentine, and enamel, or if they are bony, tooth-like protrusions. A...

The adsorption of cellulases onto fibers may be one of the most important factors affecting the enzymatic reaction between cellulases and fibers. This study investigated the adsorption kinetics involved, using isothermal adsorption equations. Cellulose binding domains (CBDs) were isolated from a commercial cellulase, and their role in the adsorption and enzymatic reaction was evaluated. Approxi...

A case of a male patient presenting with unusual dental morphology, anterior supernumerary teeth, and agenesis of premolars associated with congenital cataracts, microphthalmia and anteverted pinna is described. Although 3 similar cases are in the medical literature, this is the first case in which the dental features are described in detail. Dental anomalies associated with many congenital and...

BACKGROUND AND AIMS Visualization of the internal and external root canal morphology is very important for a successful endodontic treatment; however, it seems to be difficult considering the small size of the tooth and the complexity of the root canal system. Film-based or digital conventional radiographic techniques as well as cone beam computed tomography provide limited information on the d...

The treatment of mandibular molars has been challenging to the endodontist due to its several anatomical variations. The majority of mandibular first molars are two rooted with one mesial root and one distal root. It can have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris). Success of endodontic treatment depends on thorough mechanical and chemical clean...

Abstract Charged groups in pulp have been shown to enhance the tensile strength of paper produced from pulp. Oxygen delignification introduces charged and it is interest determine how should be distributed between cooking oxygen stage with respect mechanical properties. A number unbleached kraft cooked delignified pulps within a wide kappa range were refined, effects refining on morphology prop...

BACKGROUND The aim of this study was to investigate the physical properties and biological effects of an experimentally developed injectable premixed calcium-silicate root canal sealer (Endoseal) in comparison with mineral trioxide aggregate (MTA) and a resin-based sealer (AHplus). METHODS The pH, solubility, dimensional change, flow, and radiopacity of the materials were evaluated. Biocompat...
