AIM To assess the nociceptive and antinociceptive effects of white mineral trioxide aggregate (WMTA) using the orofacial formalin test in rats. METHODOLOGY Rats (n = 10 in each group) were separately injected into the ipsilateral upper lip with either 40 microL of a 2.5% formalin solution and eugenol (50 mg kg(-1)) or WMTA (5, 10 and 20 mg dissolved in(More)
The aim of this report is to describe the positive effect of plasma-rich in growth factor (PRGF) on pulp regeneration and apex formation in cases with necrotic pulps and open apices. After access cavity preparation and cleaning of the canal, triple antibiotic paste was inserted into the canals for the purpose of disinfection. After two weeks, apical(More)
AIM To compare the apical seal of lateral condensation technique, thermafil and one-step by using this model. MATERIALS AND METHODS A two-chamber bacterial microleakage model using E. faecalis as microbial marker was used for evaluation of the leakage. Bacterial penetration was monitored over a 60-day period. Leakage was recorded when turbidity was(More)
We examined the macronutrient intake of residents in Padang area, West Sumatra, Indonesia. The daily energy intake (1130±420 kcal) of elderly people in a rural traditional group was significantly lower than that in an urbanised "modernised" group (1700±460 kcal) (p<0.01). Even in young urbanised people (younger than 60 years old), 44.2% were below 2000 kcal(More)
INTRODUCTION The purpose of this case series was to report the clinical and radiographic results of a pulp regenerative procedure using platelet-rich fibrin (PRF), a second-generation platelet concentrate, in immature teeth with necrotic pulps. METHODS Root canal revascularization using PRF was performed on 4 immature teeth with necrotic pulps. After(More)
INTRODUCTION Mineral trioxide aggregate (MTA) is an endodontic material with different clinical applications e.g. root-end filling, pulp capping and perforation repair. It has been reported to possess antimicrobial and antifungal activities. The aim of this study was to examine the effect of White MTA on formalin-induced hyperalgesia in a rat with(More)
The aim of this study was to perform a literature review of published in-vitro and ex-vivo studies, which evaluated microbial leakage in endodontics in the past 10 years. A comprehensive electronic literature search was carried out in PubMed database for English articles published from 2005 to 2016 using the keywords "endodontics," "in vitro," "ex vivo,"(More)
BACKGROUND The aim of this study was to compare the antibacterial efficacy of endemic Satureja Khuzistanica Jamzad (SKJ) essential oil as root canal irrigation versus 2.5% sodium hypochlorite and 2% chlorhexidine gluconate. METHODS In current in vitro experimental study, fifty four single-rooted teeth were randomly divided into 6 groups of 9 samples: 2.5%(More)
The aim of this study is to compare the effect of treated dentine matrix (TDM) and tricalcium phosphate (TCP) scaffolds on odontogenic differentiation and mineralization of dental pulp stem cells (DPSCs) in furcation perforations created in the pulp chamber floor of premolar teeth in dogs. DPSCs were isolated and cultured from the dental pulp of the(More)
