1. Rebonding of unused brackets with different orthodontic adhesives
OBJECTIVE: To compare in vitro shear bond strength (SBS) of different orthodontic adhesives in bonding and repeatedly rebonding metal brackets, and to evaluate the bond failure site with the adhesive remnant index (ARI). METHODS: Specimens consisted of 90 extracted human first premolars, randomly divided into three groups (n=30). The adhesives Alpha Plast (A

2. Morphological analysis of glass, carbon and glass/carbon fiber posts and bonding to self or dual-cured resin luting agents
OBJECTIVE: The aim of this study was to evaluate the morphology of glass (GF), carbon (CF) and glass/carbon (G/CF) fiber posts and their bond strength to self or dual-cured resin luting agents. MATERIAL AND METHODS: Morphological analysis of each post type was conducted under scanning electron microscopy (SEM). Bond strength was evaluated by microtensile tes

3. Avaliação da resistência ao Cisalhamento de braquetes novos recolocados com diferentes resinas ortodônticas / Evaluation of shear bond strength of new metallic brackets rebounded with different orthodontic resins
The present study evaluated in vitro the shear bond strength of new bonded and rebounded metallic brackets with three orthodontic composites. Ninety extracted first superior premolars were randomly divided in three groups, according to the different tested composite. All bonding procedures followed the manufacturers specifications with a 300g standard pressu

4. Analise in vitro da resistencia ao cisalhamento de braquetes metalicos submetidos a reciclagem repetida : fixados com diferentes materiais
The aim of this research was to evaluate in vitro shear bond strength of metallic orthodontic brackets submitted to two consecutive recyclings with aluminium oxide air abrasion, making use of four different bond materials. The sample consisted of 40 bovine incisives. Forty metallic orthodontic edgewise brackets of central incisor Ultraminitrim (Dentaurum), w

5. Regeneração térmica de areia ligada quimicamente
The thermal reclamation of sand discarded in the process of molds and cores production with chemically bonded sand consists of a technical and economically viable option for the foundry industry, making possible the reuse in the original process. The present research approaches the study of the characteristics of thermally reclaimed core sand and the respect
