BACKGROUND In the past few years, there has been a major research drive to increase bond strength between dental materials and dental hard tissue and to reduce the associated demineralization around fixed orthodontic appliances. Thus, a recent approach is to incorporate an antibacterial agent into the primer to reduce the demineralization and enhance bond strength. The objective of this study w...

INTRODUCTION This study compared the dentoalveolar and skeletal effects on Class II malocclusions of the distal jet with concurrent full fixed appliances and the pendulum appliance both followed by fixed appliances. METHODS The 2 samples each consisted of 32 subjects (19 girls and 13 boys) with mean ages at the start of treatment of 12 years 3 months in the distal jet group and 12 years 6 mon...

The purpose of this study was to investigate the effect of treatment of mandibular crowding with self-ligating and conventional brackets on dental arch variables. Fifty-six patients were selected from a pool of subjects satisfying the following inclusion criteria: non-extraction treatment in the mandibular or maxillary arches, eruption of all mandibular teeth, no spaces and an irregularity inde...

Non-destructive testing was used to predict the static modulus of elasticity (MOES) Scots pine (Pinus sylvestris) timber from northeast Spain. Three vibration tests were performed, longitudinal, flatwise and edgewise, obtain dynamic (MOEdyn) based on fundamental resonant frequencies. The MOEdyn additionally obtained ultrasound tests. Measurements different features performed various samples, wh...

This study investigated the long-term outcome of 27 consecutive young patients diagnosed with pseudo Class III malocclusion treated with simple fixed appliance (2 x 4 appliance), which resulted in a positive overjet in all cases. Of the original sample of 27 patients, 25 patients (93%) were examined at the five-year follow-up. Two patients dropped out soon after the active treatment was complet...

Imprecision in treatment response has been defined as inconsistent unpredictable results from the same treatment. Bias has been defined as systematic failure to achieve defined treatment goals. Concepts of imprecision and bias are applied to the results of a study of soft-tissue response to Class II treatment with edgewise and Herbst appliances.

This study described changes in mandibular movements during pronunciation of /m/ and /s/ sounds in Portuguese, in patients presenting dental wear before and after appliance insertion and tooth reconstruction. Subjects were divided into a control group of dentate patients and an experimental group of patients with incisal tooth wear due to bruxism. A magnetic jaw tracking device measured the jaw...
