CLCN7 gene encodes the voltage gated chloride channel 7 (ClC-7) in humans. The mutations in CLCN7 have been associated with osteopetrosis in connection to the abnormal osteoclasts functions. Previously, we found that some osteopetrosis patients with CLCN7 mutations suffered from impacted teeth and root dysplasia. Here we set up two in vivo models under a normal or an osteoclast-poor environment...
INTRODUCTION Short Root Anomaly (SRA) is an uncommon disease and a challenge for orthodontic treatment as it tends to increase the risk of root resorption. OBJECTIVE Assess the current status of the diagnosis, etiology and orthodontic management of teeth with SRA, and present case reports. METHODS A literature review was carried out in PubMed, SciELO, LILACS, Scopus and Web of Science datab...
BACKGROUND Hypophosphatasia is a rare inherited disease derived from mutations in tissue non-specific alkaline phosphatase genes, with typical oral symptoms including short root anomaly and dysplasia of dentin or cementum. CASE PRESENTATION Two young female patients presented with short root anomaly with a history of premature loss of deciduous and/or permanent teeth. The laboratory and imagi...
The relatlon between the bonding eMcacy ef the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated, The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized O,5M EDTA solution (pH7.4) and 9.1% pyruvic acid containing 9,1% glycin, prior to the comb...
BACKGROUND Orodental diseases include several clinically and genetically heterogeneous disorders that can present in isolation or as part of a genetic syndrome. Due to the vast number of genes implicated in these disorders, establishing a molecular diagnosis can be challenging. We aimed to develop a targeted next-generation sequencing (NGS) assay to diagnose mutations and potentially identify n...
INTRODUCTION ADHESIVE DENTISTRY • Indications for Use of Adhesives • Advantages of Bonding Techniques • Mechanism of Adhesion • Factors Affecting Adhesion ENAMEL BONDING • Steps for Enamel Bonding • Mechanism of Etching DENTIN BONDING • Conditioning of Dentin • Priming of Dentin • Moist vs Dry Dentin DENTIN BONDING AGENT • Mechanism of Bonding • Evolution of Dentin Bonding Agents • Nanofilled B...
The mechanical properties of enamel and dentin were studied using test specimens having the same shape and dimensions because these properties might vary with the experimental conditions and specimen shapes and dimensions. Healthy human teeth were used as specimens for mechanical tests. The stress (MPa), strain (%), and elastic modulus (E, MPa) of the specimens were obtained from compression te...
The purpose of this study was to test the hypothesis that both human and bovine sclerotic dentin have similar hardness properties, in addition to similar micromorphological characteristics. Sixteen teeth (8 human and 8 bovine) exhibiting exposed dentin in the incisal edge and showing characteristics typical of sclerosis were used. Vickers surface microhardness testing was conducted. Three areas...
PURPOSE This study compared the dentin collagen cross-linking potential of carbodiimide (EDC) prepared in three most commonly used solvents in dental adhesive systems: water, ethanol, and acetone. MATERIALS AND METHODS Thirty-eight extracted caries-free human permanent molars were used in this study. Demineralized dentin beams were prepared and cross linked by 0.3 M EDC in water, acetone, or ...
Introduction Craniometaphyseal dysplasia (CMD) is a rare craniotubular bone dysplasia transmitted in autosomal dominant or recessive form. This disease is characterized by cranial bone hyperostosis and deformity of the metaphyses of the long bones. Using osteoclast-like cells formed from patient bone marrow cells, we investigated the pathophysiology ofCMD in a 3-yr-old patient. Untreated bone m...
