CUIDADOS BUCALES EN PACIENTES CON FISURAS DE LABIO Y/O PALADAR

The aim of our study was to accomplish a review about dental cares in pacients with cleft lip and palate. Few papers are published about this theme, and consequently only specialized professionals are prepared to guide the parents appropriately on the preventive procedures. In accordance with the fissure type, the appropriate period for the surgical intervention is defaulted, and appropriates health and dental hygiene pattern before the surgery are decisive factors for a satisfactory clinical recovery.KEY WORDS: buccal care, cleft lip, cleft palate, review. RESUMENLa propuesta del estudio fue proporcionar una revisión de los cuidados bucales en pacientes con fisura de labio y/o paladar. Pocos trabajos fueron publicados con el tema, y con esto, solamente profesionales especializados son preparados a direccionar de forma apropiada a los padres en relación a los procedimientos preventivos. Teniendo en cuenta el tipo de fisura, se padroniza el mejor periodo para la intervención quirúrgica, en que la salud y higiene dental son primordiales para una recuperación clínica satisfactoria.PALABRAS- CLAVE: cuidados bucales, fisura labial, fisura paladar, revisión.RESUMOA proposta do estudo foi realizar uma revisão dos cuidados bucais em pacientes com fissuras de lábio e/ou palato.

Influence of luting agents on time required for cast post removal by ultrasound: an in vitro study

OBJECTIVE: This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal. MATERIAL AND METHODS: After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing acrylic resin. After casting procedures using a nickel-chromium alloy, the posts were randomly distributed into 3 groups (n=10) according to the luting material: G1- zinc phosphate (SS White) (control group), G2 - glass ionomer cement (Vidrion C; SS White), and G3- resin cement (C&B; Bisco). In G3, the adhesive procedure was performed before post cementation. After 24 h, the cement line was removed at the post/tooth interface using a fine diamond bur, and the ST-09 tip of an Enac ultrasound unit was applied at maximum power on all surfaces surrounding the posts. The application time was recorded with a chronometer until the post was completely dislodged and data were analyzed by ANOVA and Tukey's test (p<0.05). RESULTS: The roots were removed from the acrylic resin and inspected to detect cracks and/or fractures. The means for G1, G2, and G3 were 168.5, 59.5, and 285 s, respectively, with statistically significant differences among them. Two G3 posts resisted removal, one of which developed a vertical fracture line. CONCLUSIONS: Therefore, the cement type had a direct influence on the time required for ultrasonic post removal. Compared to the zinc phosphate and glass ionomer cements, the resin cement required a longer ultrasonic vibration time
