Cost-effectiveness and Acceptance in Children and Parents of the Hall Technique: Systematic Review of Clinical Trials.

Aims: The purpose of this systematic review was to evaluate the cost-effectiveness and acceptance of children and their parents of the Hall technique (HT) for dental rehabilitation in pediatric dentistry.

Background: The approach of the HT is that of minimally invasive treatment of the dental element and is used exclusively on primary molars. Various studies in the literature point to HT as a restorative option well accepted by children and parents and quite predictable, with low retreatment rates and good cost-effectiveness for the management of primary molars with carious lesions.

Optical clearing agents based on metallic and dielectric nanoparticles for caries diagnostic by optical coherence tomography.

Objective: This study aimed to assess the effect of titanium dioxide (TiO) and silver (Ag) nanoparticles dispersed in glycerol or water, serving as optical clearing agents nanocolloids (OCAs-NC), for improving optical coherence tomography (OCT) images and highlighting incipient lesions in ex vivo human teeth.

Materials And Methods: Twelve human teeth with incipient lesions were divided into seven groups according to the OCA-NC; they were subjected to G1 (air), G2 (glycerol), G3 (TiO 0.1%), G4 (TiO 0.

Malignant hyperthermia in maxillofacial surgery: Literature review supported by case presentation.

Objective: Malignant hyperthermia (MH) is characterized by a state of hypermetabolism after exposure to halogenated inhalational anesthetics or succinylcholine. The aims of this study were to carry out an updated review on the subject and report an illustrative case of MH in urgent maxillofacial surgery.

Material And Methods: A search of the PubMed/MEDLINE database using the keyword "malignant hyperthermia" was performed including articles published over the last 11 years in English, Spanish or Portuguese.

Comparison of two alar cinch base suture in orthognathic surgery: a randomized clinical trial.

Le Fort I osteotomy is widely used in orthognathic surgery to correct maxillary deformities. However, this osteotomy may be related with the increase of alar base width. The aims of the present study were to compare two alar cinch suture after Le Fort I osteotomy and observe which type presents a better result in controlling the enlargement of the alar base after maxillary repositioning in orthognathic surgery.

Profile and costs associated with the use of osteosynthesis materials in victims of traffic accidents.

Background/aims: Facial trauma arising from traffic accidents is one of the most prevalent injuries in urban trauma centers. The aim of this study was to evaluate the frequency, types, and costs associated with osteosynthesis material used in facial fractures of traffic accident victims seen at the Hospital da Restauração, Recife/PE, Brazil, from January to December 2014.

Materials And Methods: Data were collected from the medical records of hospitalized patients submitted to surgery under general anesthesia for the treatment of facial fractures during the period.

Pseudoaneurysm in internal maxillary artery after gunshot wound: Critical review and case report.

Introduction: Pseudoaneurysm is a vascular injury typically caused by rupture of arteries with extravasation of blood. The involvement of this entity in facial arteries after firearm aggression is extremely rare, and they need treatment as early as possible, thus avoiding irreversible damage to patients.

Study Design: A 40-year-old male victim of gunshot attack with an entrance orifice in the right posterior cervical region with ascending trajectory, lodging in the ipsilateral zygomatic-orbitary complex, which was submitted to removal of the bone fragments and the bullet.

Three-Dimensional Finite Element Analysis of Varying Diameter and Connection Type in Implants with High Crown-Implant Ratio.

The aim of this study was to evaluate the effect of varying the diameter, connection type and loading on stress distribution in the cortical bone for implants with a high crown-implant ratio. Six 3D models were simulated with the InVesalius, Rhinoceros 3D 4.0 and SolidWorks 2011 software programs.

Photodynamic Inactivation of Cariogenic Pathogens Using Curcumin as Photosensitizer.

Objective: This investigation assessed the susceptibility of Streptococcus mutans and Lactobacillus acidophilus to Photodynamic Therapy (PDT) when grown simultaneously in dentine carious lesions.

Background Data: PDT is a technique that utilizes light to activate photosensitizers in the presence of oxygen to produce reactive radicals.

Materials And Methods: A culture medium of 1% glucose, 2% sucrose, 1% young primary culture of L.

Effects of co-administered dexamethasone and nimesulide on pain, swelling, and trismus following third molar surgery: a randomized, triple-blind, controlled clinical trial.

This study aimed to determine the effect of the co-administration of dexamethasone 8mg and nimesulide 100mg given 1h before mandibular third molar surgery. A prospective, randomized, triple-blind, split-mouth clinical trial was developed at the study institution in Pernambuco, Brazil. A pilot study was first performed (95% confidence interval, 80% test power, and 5% error), and a sample of 40 patients aged between 18 and 40 years was selected.

Photodynamic effects of curcumin against cariogenic pathogens.

Background Data: The presence of Streptococcus mutans and Lactobacillus acidophilus in dental structure is an indicator of a cariogenic biofilm. Photodynamic therapy is a technique that involves the activation of photosensitizers by light in the presence of oxygen, resulting in the production of reactive radicals capable of inducing cell death. Reduction of bacteria levels can provide additional means of preventing dental caries.

The influence of composite resin restorations and lining on radiographic diagnosis and decision-making: an in vitro investigation.

The objective of this study was to evaluate the influence of resin-based restorations on the interpretation of digital and conventional radiographic images and to correlate the proposed diagnosis with decision-making. Class II cavities were prepared in one of the proximal surfaces of extracted human molars. Teeth were divided into five groups (n = 10) according to the restoratives used: Natural Flow (NF) and Filtek Supreme (FS); Filtek Flow (FF) and FS; Tetric Flow (TF) and FS; Protect Liner F (PLF) and FS; and FS alone.

Overall-mouth disinfection by photodynamic therapy using curcumin.

Background Data: Photodynamic therapy is a technique that involves the activation of photosensitizers by light in the presence of tissue oxygen, resulting in the production of reactive radicals capable of inducing cell death.

Objective: The present study assessed the overall susceptibility of pathogens of salivary flora to photodynamic therapy after sensitization with curcumin and exposure to blue light at 450 nm.

Methods: A randomized trial was executed with 13 adult volunteers.

Influence of socio-economic and demographic factors in determining breathing patterns: a pilot study.

Unlabelled: Breathing represents one of the vital functions of the organism, and its unbalance causes some series of alterations in several organs and systems.

Aim: Verify the influence of socio-economic and demographic factors in determining breathing patterns.

Study Design: cross-sectional.

Clinical comparative study of the effectiveness of two dosages of Dexamethasone to control postoperative swelling, trismus and pain after the surgical extraction of mandibular impacted third molars.

Purpose: The aim of this study was to evaluate the effect of two different concentrations (4 and 8 mg) of dexamethasone to decrease the swelling and trismus after the surgical extraction of mandibular impacted third molars.

Methods: This randomized clinical trial comprised thirty (30) adult patients of both genders with no local or systemic problems, with bilateral impacted lower third molars in similar position, where surgical extraction had been indicated. They were given 4 mg and 8 mg of dexamethasone 1 hour before the surgical procedure at the first or second surgery.
