Regeneration of dental pulp after pulpectomy was accomplished recently by autologous transplantation of dental pulp stem/ progenitor cells into the root canal. The identical patterns of qualitative and quantitative protein and mRNA expression in the regenerated pulp and normal pulp demonstrated complete pulp regeneration. The lack of tissue specific markers in the dental pulp is a major challen...

The present study examines the effect of a sympathetic stressor on a short-term memory test, and changes in cortical Beta wave amplitude, which when present, indicate active cognition. While testing these variables, heart rate (HR) and blood pressure (BP) were also recorded to ensure that sympathetic stimulation occurred; control subjects were also used as a reference to ensure that stimulation...

Previous work suggests that inductive and deductive reasoning may be accomplished by different processes. Here, we examine whether different phenomena of inductive reasoning, previously explained in the same way, may rely on different types of processes. In Experiment 1 we show that trials which examine sensitivity to sample size in inductive reasoning have greater effects on secondary task per...

Vital Pulp Protection and Therapy (VPPT) is the treatment that maintains pulp tissue in a healthy and functional state, whenever the dentin-pulp complex has been compromised by caries, trauma or restorative procedures. Pulp vitality and function is not essential for mature tooth survival. Mature permanent teeth without a vital pulp can survive for a long time after a successful endodontic treat...

INTRODUCTION Direct pulp capping procedure is a therapeutic application of a drug on exposed tooth pulp in order to ensure the closure of the pulp chamber and to allow the healing process to take place. OBJECTIVE The aim of this study was to examine the histological effects of Emdogain® on exposed tooth pulp of a Vietnamese pig (Sus scrofa verus). METHODS The study comprised 20 teeth of a V...

Endodontic regeneration shows promise in treating dental pulp diseases; however, no suitable scaffolds exist for pulp regeneration. Acellular natural extracellular matrix (ECM) is a favorable scaffold for tissue regeneration since the anatomical structure and ECM of the natural tissues or organs are well-preserved. Xenogeneic ECM is superior to autologous or allogeneic ECM in tissue engineering...

The purpose of this study was to assess the histological appearance of the pulp of human primary incisors extracted because of deep, unrestorable caries, and to determine how clinical pulp exposures affected the histological status of the pulp compared to nonexposures. Caries was removed carefully from all teeth after fixation; 24 incisors had pulp exposures, and 29 teeth had no pulp exposures....

Objectives. This study aimed to investigate the influences of N-acetyl cysteine (NAC) on cytotoxicity and mechanical properties of Poly-methylmethacrylate (PMMA) dental resins. Methods. Experimental PMMA resin was prepared by incorporating various concentrations of NAC (0, 0.15, 0.3, 0.6 and 0.9 wt.%). MTT assay was performed to investigate viability of human dental pulp cells after exposure to...

Objective. The aim of this study was to investigate quality and safety of supplemental intraoral anesthesia periodontal ligament anaesthesia (PDL) and intraseptal anaesthesia (ISA) after computer-controlled articaine delivery. Method. 54 ASA I volunteers randomly divided into 2 groups participated in this study. 0.4 ml of 4% articaine with 1:100.000 epinephrine were randomly administered with c...
