ABSTRACT
La Hipomineralización Molar-Incisivo (HMI) es un defecto de esmalte de origen sistèmico que afecta uno o varios molares permanentes, asociado en algunos casos a los incisivos permanentes. Defectos de esmalte, como la HMI pueden influenciar negativamente la calidad de vida, percepción estètica y autoestima de niños y adolescentes. Las opciones de tratamiento para este tipo de alteración, incluye desde medidas preventivas y procedimientos restauradores hasta la extracción dental. Factores como la edad y expectativas del paciente, severidad de la alteración y materiales deben ser considerados en el plan de tratamiento del paciente con HMI. La utilización de resinas compuestas para la restauración de molares e incisivos ha mostrado buenos resultados relacionados a la durabilidad y estètica. Este artículo presenta dos casos clínicos sobre el abordaje de la HMI en dientes anteriores, realizando preparos cavitários conservadores por medio de puntas ultrasónicas adaptadas a un sistema de ultrasonido y restauración con resina compuesta, obteniendo resultados estéticos favorables con un año de acompañamiento.
Molar-Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Enamel defects may produce many symptoms that have physical, social and psychological effects and influence day-to-day living or quality of life. The available treatment modalities for teeth with MIH are extensive, ranging from prevention, restoration, to extraction. Factors such as age, patient expectations, severity of the lesion and materials should be considered in the treatment of the patient with MIH. Restoration with composite resin is an alternative choice for posterior and anterior MIH defective teeth and its use has been show acceptable results. This article describes two clinical cases involving pediatric patients with MIH whose procedure of cavity preparation was based on the use of CVD ultrasound diamond tips and restored using composite resin obtaining favorable esthetics results after a 1 year follow-up.
ABSTRACT
Este estudo teve como objetivo realizar uma revisão sistemática da literatura para avaliar os efeitos dos hábitos parafuncionais de sucção sobre a ATM e estruturas adjacentes em crianças. Os artigos incluídos foram identificados por meio de pesquisas bibliográficas da Bireme, Pubmed, ClinicalTrials.gov, The National Research Register e Pro-Quest Dissertation Abstracts and Thesis, usando os termos de busca temporomandibular joint, sucking behavior and fingersucking. As pesquisas sobre os hábitos atuais ou anteriores de chupar o dedo e/ou uso de mamadeiras e chupetas e a presença de dor na ATM com crianças até 12 anos foram incluídas. Oito estudos foram selecionados, e 4 apresentaram uma associação, mas sem significância estatística. Os achados científicos demonstram uma associação baixa ou ausente de DTM com hábitos de sucção parafuncionais.
Objective: To assess the attitudes and knowledge about hepatitis by scholars and dental practitioners from Recife and its metropolitan region. Method: The research protocol was submitted and approved by the Ethics and Human Research Committee of the Federal University of Pernambuco. There were included 230 undergraduate students in dentistry and 104 dentists who exercise their professional activity in Recife and its Metropolitan Region. They signed a consent form and answered a questionnaire, the evaluative instrument, with objective questions about biosafety, transmission of hepatitis and sexually transmitted diseases. Results: About the types of hepatitis 133 (57.8%) students and 61 (58.7%) professionals claimed to know the types A, B and C. Concerning transmission 31 (13.5%) students and 25 (24.0%) professionals said that the main route of transmission were sexual and bloodstream respectively. Relating to imunization 221 (96.1%) students and 99 (95.2%) professionals reported that have been vaccinated against hepatitis B, however, only 126 (54.8%) students and 55 (52.9%) professionals have followed the immunization's schema. Regarding the cleaning of the office equipment, 18.7% of the students replied that they do not know who does it. 56.7% of professionals said that it was performed with alcohol 70 ° GL.Conclusions: The findings indicate that there is a concern for biosafety but the knowledge about the forms of hepatitis transmission and biosecurity measures need to be better settled.
