introduction: an overlooked but important part of successful root canal treatment is a straight-line access (sla). the purpose of this in vitro study was to compare the efficacy of introfile and prerace rotary instruments with gates glidden (gg) drills in gaining sla by cone-beam computed tomography (cbct). methods and materials: a total of forty five extracted mandibular first molars were sele...

Introduction Quantification of carious lesions and measurement of the distance to the pulp is an important task in conservative dentistry. This information can improve identification of cases with the potential for maintaining pulp vitality and monitor treatment success of indirect pulp capping. In the procedure of indirect pulp capping the nearly exposed pulp is covered with a chemical (usuall...

Despite the fact that it is preventable, dental caries remains a global public health problem—even with fluoride intervention—and it is the most common chronic disease on the planet. Moreover, researchers have already shown for some years that caries is a disease continuum that at the early stages is reversible, yet many Ministries of Health and dental professionals misunderstand this. We belie...

The aim of this study was to demonstrate construct validation of the haptic virtual reality (VR) dental simulator and to define expert benchmarking criteria for skills assessment. Thirty-four self-selected participants (fourteen novices, fourteen intermediates, and six experts in endodontics) at one dental school performed ten repetitions of three mode tasks of endodontic cavity preparation: ea...

Fermented papaya preparation (FPP) is a "natural health product." The high incidence of dental caries, gingivitis, periodontitis, and oral microbial infection cases among patients with diabetes mellitus continues to prevail. The potential role of FPP against common oral microbiota (Streptococcus mutans, Streptococcus mitis, and Lactobacillus acidophilus) isolated from the human oral cavity was ...

The mode of acquisition of gastric Helicobacter spp. infection in dogs has not been determined. It is suspected that oral-oral and faecal-oral transmission may be involved. The present study sought to determine if Helicobacter spp. DNA is present in the oral cavity of healthy and vomiting dogs. Thirty-eight pet dogs (27 vomiting and 11 clinically healthy) were studied. The presence of Helicobac...

INTRODUCTION Standard treatment for caries removal and cavity preparation for restorations using mechanical means is often accompanied by fear and pain for the patient. Although the pain may be reduced by local anaesthesia, fear of the needle, noise, and the vibration of mechanical preparation remain a cause of discomfort. Erbium, chromium:yttriumscandium- gallium-garnet (Er,Cr:YSGG) laser irra...

OBJECTIVES A review is made of the clinical, diagnostic, therapeutic and survival characteristics of Ewing sarcoma (ES) of the oral cavity. MATERIAL AND METHODS A systematic literature search was carried out, with restrictions referred to time (1960-2014), language (English and Spanish) and type of study (case reports, letters, datasets, reviews). The following MeSH terms and boolean operator...

The effect of variations in the design of class-II cavity preparations on the marginal degradation of amalgam restorations was included as a study aim in a clinical trial. Four hundred and sixty-eight restorations were placed in 210 patients by 7 Scandinavian dentists using 5 different alloys. The marginal degradation was scored on impressions of the restored teeth by means of a six-point ordin...

AIM To evaluate the effectiveness of haptic virtual reality (VR) simulator training using microcomputed tomography (micro-CT) tooth models on minimizing procedural errors in endodontic access preparation. METHODOLOGY Fourth year dental students underwent a pre-training assessment of access cavity preparation on an extracted maxillary molar tooth mounted on a phantom head. Students were then r...
