The objective of this study was to compare the flexural strength and elasticity modulus of two types of staple reinforcement fibers, Interlig - Angelus/glass (Londrina, PR, Brazil) and Connect - KerrLab(R)/polyethylene (MFG Co., West Collins Orange, CA, USA), which are widely used in Dentistry for chairside use, after varying the number of layers employed and submitting or not to thermocycling. This study was performed on 72 specimens, divided into 8 groups: G1 - single layer of Interlig fibers without thermocycling; G2 - double layer of Interlig fibers without thermocycling; G3 - single layer of Interlig fibers with thermocycling; and G4 - double layer of Interlig fibers with thermocycling; G5 - single layer of Connect fibers without termocycling; G6 - double layer of Connect fibers without termocycling; G7 - single layer of Connect fibers with termocycling; G8 - double layer of Connect fibers with termocycling. For each group, values for flexural strength and elasticity modulus were obtained. The polyethylene fiber employed in a double layer presented the highest flexural strength (p < 0.05), independently of thermocycling (p < 0.001), when compared to the other evaluated combinations. The polyethylene fiber, used in a single layer without thermocycling, demonstrated a significantly higher elasticity modulus, when compared to the other groups (p < 0.05). Within the limits of this study, it was concluded that the polyethylene fiber in a double layer appears to be more resistant, regardless of whether it was submitted to thermocycling or not.
Ankyloglossia is an anatomical variation that has been associated with a variety of problems such as: suckling, swallowing and speaking. In this perspective, frenotomy is a surgical procedure commonly performed on babies to correct ankyloglossia. In this sense, the objective of this work is to report a clinical case of ankyloglossia in which the frenotomy procedure was performed on twin newborns, who had difficulty breastfeeding, carried out in the Extension Project “Língua Solta”, from the Federal University of Pernambuco. The evaluation of the lingual frenulum followed the protocol recommended by Martinelli, 2013. After application of the protocol, newborns showed the need to perform frenotomies. The surgeries were performed and, after 7 days, the babies showed significant improvement in breastfeeding. The diagnosis made, through the protocol and experienced professionals, is of fundamental importance for the success of the surgery. In addition, early intervention contributes to improved breastfeeding and development of the newborn.
A distração osteogênica para avanço mandibular é um tratamento viável para pacientes portadores de deformidades dentofaciais, além de ser o tipo de dis- tração mais utilizada nos ossos maxilofaciais. É muito empregada nos casos de micrognatia mandibular, em que é necessário realizar avanços de grande magnitude. A distração osteogênica favorece a harmonia facial, recupera a função do sistema estomatognático, a fonação, além de ser uma alternativa à osteotomia sagital bilateral do ramo mandibular. O objetivo do presente estudo é descrever um relato de caso clínico de uma paciente com 9 anos de idade, que apresentou um quadro de limitação de abertura bucal acentuada, micrognatia mandibular de causa idiopática, assim como discutir a utilização da distração osteogênica como conduta terapêutica para esta deformidade dentofacial.
