INTRODUCTION This study evaluated the root canal wall morphology under scanning electron microscopy magnification after removal of 2 types of root canal fillings by using ultrasonic tips, nickel-titanium (NiTi) rotary instruments, and hand K-files. METHODS Thirty-six extracted roots were filled by using AH Plus (DeTrey-Dentsply, Konstanz, Germany) as a(More)
PURPOSE The purpose of this study was to investigate the effect on enamel surface morphology of two commercially available bleaching products (AZ Whitestrips 6% hydrogen peroxide - Procter & Gamble; Platinum TWS 10% carbamide - Colgate Oral Pharmaceuticals) and their ability to prevent enamel demineralization in the presence of cariogenic solution, with or(More)
AIM This was to validate a taste test on healthy school children. A cross-sectional study was designed to perform a standardised clinical evaluation of the gustatory sensitivity. MATERIALS AND METHODS Forty (18 males and 22 females) children were selected. Inclusion criteria were age between 5 and 12 years, absence of systemic disease and no antibiotic(More)
Alagille Syndrome (AGS) is a genetically determined multisystem disorder affecting liver, hearth, eyes, skeleton and facies, less commonly kidney and CNS. The prognosis depends on the severity of the associated anomalies. The liver pathology plays a central role in that most clinical complications are due to long standing cholestasis as a consequence of(More)
Combined methylmalonic aciduria and homocystinuria (MMA-HC) is a rare metabolic disease characterized by an inborn defect in B12 vitamin metabolism. This case report concerns an 11-year-old patient with MMA-HC, which developed during the neonatal period. The patient shows some of the facial features that were already reported in the literature (high(More)
OBJECTIVE The aim of this study was to evaluate the fluoride release (release-tests) from two glass-ionomer cements (GIC), before and after NaF solution treatment (fluoride treatment) in different pH environments. MATERIALS AND METHODS After 21 days, every second sample was submitted to fluoride treatment to simulate a fluoride recharge. After fluoride(More)
This study tested the hypothesis that hybridization of intraradicular dentin eliminates interfacial gaps, thereby improving the coronal seal and retention of teeth restored with fiber posts. Post spaces were bonded with two types of fiber posts, using the corresponding etch-and-rinse adhesives and dual-cured resin cements. Longitudinal sections of the(More)
BACKGROUND The authors describe dental and periodontal conditions of two Chinese sisters affected by familial hypomagnesemia with hypercalciuria and nefrocalcinosis (FHHNC). FHHNC is a rare syndrome, genetically investigated since 1999, transmitted as an autosomal recessive disease. It is related to a mutation of PCN-1 gene which encodes for a tight(More)
The aim of this study was to describe the clinical treatment of young patients, affected by ectodermal dysplasia (ED), and to possibly establish clinical guidelines. The study design was case series. ED syndromes (EDs) are a heterogeneous group of inherited diseases characterised by abnormal development of tissues of ectodermal origin. The most common form(More)
X-linked hypophosphatemia (XLH) is a genetic disorder related to alterations in bones and teeth formation, due to low levels of phosphate in blood. Oral findings in XLH have been enamel and dentine abnormalities, high pulp horns, large pulp chambers, and some cases of periapical abscesses related to teeth without caries or traumatic injuries. The aim of our(More)
