UNLABELLED Evidence-based dentistry is a critical evaluation, awareness of the available evidence to improve decision making about the care of individual patients and/or communities. OBJECTIVE To systematically analyze the available scientific literature on clinical and radiographic results of two materials used in pulpotomy in primary teeth: formocresol and mineral trioxide aggregate. MATE...

Mineral trioxide aggregate (MTA) has recently been used as a pulpotomy medicament for primary molars. The aim of this study was to evaluate and compare the proliferation and differentiation potential of dental pulp stromal cells of permanent teeth and deciduous teeth cultured on MTA-coated surface. Human dental pulp stromal cells were obtained from human permanent premolars and deciduous teeth ...

The purpose of this study was to determine the level of agreement between pediatric dentists and endodontists at a pulp therapy symposium conjointly sponsored by the American Association of Endodontists (AAE) and the American Academy of Pediatric Dentistry (AAPD) on November 2-3, 2007. Presymposium and postsymposium tests were administered, and respondent answers were compared between pediatric...

OBJECTIVE The aim of this study is to evaluate four different pulpotomy medicaments in primary molars. MATERIALS AND METHODS A total of 147 primary molars with deep caries were treated with four different pulpotomy medicaments (FC: formocresol, FS: ferric sulfate, CH: calcium hydroxide, and MTA: mineral trioxide aggregate) in this study. The criteria for tooth selection for inclusion were no ...

Considerable interest has been focused on miniature biofuel cells (BFCs) because of their portability and possibility to be implantable. Origami devices with hollow channels will provide novel insight into the assembly methods of miniature BFCs. Herein a miniature origami BFC has been fabricated from a MnO2-graphite flake consumed solid-state cathode. For further practical applications, miniatu...

Stingless bees may produce both large queens and "miniature" queens, but the adaptive significance of this is uncertain. Using biometry and statistical analysis we determined the proportion of miniature queens in Plebeia remota that were either mated (14%) or virgin (45%). Mated queens were mostly normalsized which indicated that they were more successful. Nevertheless, the presence of miniatur...

The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...

A student once told me that he preferred to work with another instructor because I took too long to make clinical decisions. When 1 asked him why, he gave me several examples of situations in which I had deliberated upon too long for his liking. None of these was simple in my opinion, nor did I agree with the other instructor's solutions. My dismay and introspection about this student's revelat...

The aim of this study was to evaluate histological aspects of the pulp-dentin complex of dogs submitted to pulpotomy and capped with ethyl-cyanoacrylate and calcium hydroxide. Thirty dog teeth were divided into 2 groups of 15 as follows: Group 1 - ethyl-cyanoacrylate; Group 2 - calcium hydroxide. The pulpotomies were carried out following all of the treatment precautions recommended for dogs. A...
