SUMMARY OBJECTIVES The purpose of this study was to investigate time-related dental tissue reactions to tooth replantation in mature and immature human premolars by histomorphometric and radiographic methods. MATERIAL AND METHODS Sixty premolars were extracted, immediately replanted (T0), and left without intervention for 1, 2, 3, 6, 12, and 24 weeks before re-extraction (T1). Periapical radi...

High-sucrose diet and metabolic acidosis have some similar effects on bone and they both reduce the formation of dentine. This series of experiments was conducted in order to get information about the effects of acidosis and alkalosis on dentine during primary dentinogenesis and also to ascertain if high-sucrose diet affects dentine formation via acidosis. Chronic metabolic acidosis (0.25 mol/L...

The ability of ozone to kill micro-organisms associated with non-cavitated occlusal caries was investigated. The occlusal surfaces were treated with ozone (n = 53) or air (n = 49) for 40 s, and the underlying infected dentine was exposed. There was no significant difference between the number of bacteria recovered from the ozone-treated and the control sites (p > 0.1). Treatment of the exposed ...

BACKGROUND Translucency of dentine is the result of occlusion of the corresponding dentinal tubules by a mineral substance which has a refractive index similar to that of the rest of the dentine. CASE PRESENTATION This case report describes the microradiographic features of an upper cadaveric canine. Transverse microradiograph is one of the methods assessing apical dentine translucency for va...

The diffusion through dentine by a number of biological and synthetic molecules, including resins and dyes, is reported. In vitro measurements were derived by experiments with a modified 'split-chamber device'. Diffusion was found to be indirectly proportional to dentine thickness for all molecules. Permeability of water-soluble molecules and ethanol-soluble molecules was proportional to the mo...

Received: January 06, 2017; Accepted: January 16, 2017; Published: January 18, 2017 One of the most important components in dentistry is dentine, which is a complex structure with a high organic component. Majority of its organic component is consisted of collagen type I fibres followed by collagen type III, proteoglycans, MMPs and cysteine cathepsins. Thus, dentine can be introduced as one of ...

The objective of this study was to analyse the stress distribution in periodontal ligament and tooth structure a cementum-reinforced tooth, dentine-reinforced an immature during orthodontic loads using finite element analysis. A model maxillary incisor its supporting tissues developed. root segmented into two parts: part that represented state apical tissue formed after regenerative endodontics...

CONTEXT The gold standard treatment modality for dentine hypersensitivity has not yet been established. This review examines the effectiveness of self and professionally applied treatments for the reduction in pain from dentine hypersensitivity. MATERIALS AND METHODS Electronic (three databases) and hand searches were performed 14-21 July 2014 to identify randomized controlled trials for the ...

The purpose of this in vitro study was to evaluate the shear bond strength of glass ionomer sealer to dentine exposed to common endodontic irrigants in both well and poorly prepared dentine surface. In the methodology four groups of elephant dentine sample were used. Each group was well cleaned and prepared with different irrigants for the effective removal of smear layer. One group was treated...
