BACKGROUND The authors undertook a study to measure how the addition of amorphous calcium phosphate (ACP) to a professionally dispensed 16 percent carbamide peroxide equivalent bleaching gel affects tooth color and dentinal hypersensitivity. METHODS The authors assigned two groups to use either the test gel containing ACP or a control gel. Both groups used their respective products for three ...

BACKGROUND High dose oral ascorbic acid substantially improved myelination and locomotor function in a Charcot-Marie-Tooth type 1A mouse model. A phase II study was warranted to investigate whether high dose ascorbic acid also has such a substantial effect on myelination in Charcot-Marie-Tooth type 1A patients and whether this treatment is safe. METHODS Patients below age 25 years were random...

In this paper, a double-side milling method on spiral bevel gear is proposed. First, according to the tooth taper processed by method, influence of dedendum angle was researched. Taking cut parameters into comprehensive consideration, geometric were designed through inclination root line and modified mean point in which machine setting calculated selected. Only met meshing equation, error press...

OBJECTIVE The purpose is to compare temperature rise in the pulp chamber during fabrication of provisional crowns using different materials and on different types of teeth using direct technique. MATERIALS AND METHODS An extracted, sound, caries free maxillary central incisor and a mandibular molar were selected for the study and crown preparations of all ceramic and all metal were done on ce...

Mechanical errors seriously affect the transmission performance of mechanical structure, especially for high-precision structure. With development virtual simulation technology, test structure in environment is gradually applied. Under background, this paper takes movable tooth reducer as research object and puts forward a method by combing with technology. The profile key components are obtain...

introduction:there are conflicting reports on the effects of surgical removal of impacted mandibular third molars on the periodontium of the adjacent teeth. the aim of this study was to compare the condition of the periodontium six months after extraction of impacted mandibular third molars with baseline values. methods: fifty patients with mesioangular impacted mandibular third molarsparticipa...

introdouction:tooth eruption is recognized as an important aspect of human growth and development. it can be influenced by a number of factors, and it may reflect the general development of a child’s body. the purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the city ...

Introduction Regenerating a tooth completely in human oral cavity is not achieved by current studies yet. Here, we have conceived a man-induced method to construct a teeth germ which might be used to regenerate a tooth in vivo. This idea was generated by traits of the development of the compound odontoma, a benign tumour of tooth malformation. This is a kind of developmental tooth malformation,...
