i ntroduction: nano-hydroxyapatite (nha) has been used for regeneration of osseous defects. calcium-enriched mixture (cem) cement is also used for various dental treatments. this trial compared the efficacy of nha and cem cement for direct pulp capping (dpc) of sound primary teeth. methods and materials: in this randomized clinical trial with split-mouth design, after attaining informed consent...

BACKGROUND The association between chronic respiratory diseases and work disability has been demonstrated a number of times over the past 20 years, but still little is known about work disability in occupational cohorts of workers exposed to respiratory irritants. This study investigated job or task changes due to respiratory problems as an indicator of work disability in pulp mill workers occu...

Epidemiologic aspects of traumatic dental injuries (TDI) were evaluated in the permanent dentition in a sample of 847 patients treated at the Dental Urgency Service of the Dental School of the Federal University of Goiás, Brazil, between May 2000 and May 2008. The statistical treatment analyzed data from frequency distribution and chi-square test. The level of significance was set at 5% for all...

OBJECTIVE In the present study, we examined whether 2, 2-bis [4-(2-hydroxy-3-methacryloxypropoxy) phenyl] propane (Bis-GMA) has effects on LSC2 cells, human dental pulp cell line. MATERIAL AND METHODS The viability, cell cycle, and morphology of LSC2 cells were analyzed after exposure to several different concentrations of Bis-GMA. The recovery of viability of Bis-GMA exposed cells was also a...

OBJECTIVES The aim of the present study was to investigate the effects of lipopolysaccharide (LPS) on the migration and adhesion of human dental pulp stem cells (hDPSCs) and the associated intracellular signalling pathways. METHODS hDPSCs obtained from impacted third molars were exposed to LPS and in vitro cell adhesion and migration were evaluated. The effects of LPS on gene expression of ad...

The objective herein was to evaluate the effect of processing, packaging type (with and without exposure light) storage time on quality functional attributes jelly prepared from curriola pulp. experimental design a completely randomized 2 × 5 factorial design, with two levels (transparent amber) five periods (0, 3, 6, 9 12 months). In general, processing pulp determined slight increase in pheno...

AIM Several new techniques and materials for in-office bleaching have been introduced recently. The aim of this in vitro study was to measure the temperature increase in the pulp chamber of extracted teeth produced by the Zoom! in-office bleaching system and to investigate the influence of this light in conjunction with the bleaching gel on pulp temperature rise. METHODS AND MATERIALS Ten ext...

The purpose of this study was to assess the pulp healing process in baboon teeth after pulpotomy using an enriched collagen solution (ECS) as a pulp dressing. Twenty-five noncarious permanent teeth of two young baboon monkeys were pulpotomized under a rubber dam. After coronal pulp resection and hemostasis, ECS was applied on the pulp stumps and covered with sterile dental wax. The controls wer...
