Brazilian adaptation of the Woodcock-Johnson III cognitive tests

An adaptation of the standard battery of Woodcock-Johnson III Tests of Cognitive Abilities (WJ-III) for Brazilian children and youth was investigated. The sample was composed of 1094 students (54 percent girls), ages 7-17, living in Sao Paulo state (91 percent). Items from Brazilian school books as well as from the WJ-III Spanish version (Bateria-R) were added to comprehension-knowledge tests. Brazilian words were adapted to the auditory tests according to syllabic division and stressed syllables. Items were examined through IRT and age differences through analysis of variance. Results indicated the need to remove items from all WJ-III subtests with the exception of the visual learning test. Analysis of Variance indicated significant age differences (p <= 0.001) for all tests. Thus, the importance of a Brazilian adaptation for the WJ-III was confirmed.

Diagnóstico e tratamento precoce da Classe III: relato de um caso clínico

In malocclusion studies, may happen not only dental discrepancies but even skeletal discrepancies. In Class III malocclusion can be observed underdeveloped maxilla, mandible protraction or both of them, and, in most of the times associated with a narrow maxilla that causes anterior or posterior crossbites, in one side or in two sides. The aim of this case report is to evaluate the facial profile and occlusal effects of interceptive orthodontics therapy. The treatment with upper arch expansion and maxilla protraction was done in an early age to be effective in the circummaxillary sutural system and to make the orthopedic effect easier. The facial mask used is positioned on two facial points and allows an anterior maxillary replacement. Patients’ compliance is important to reach treatment success, this because using the mask still in this growth and development phase is essential to make the facial and occlusal effects happen. It is important to mention that patients with Angle Class III malocclusion need to be followed till the end of their growth.

Aparelho extrabucal como recurso auxiliar para alinhamento e nivelamento no tratamento orto cirúrgico de má oclusão classe III esquelética

When well indicated, the orthodontic surgical approach is the ideal treatment mean for Skeletal Class III adult patients. To improve facial esthetic results from orthognatic surgery, the leveling and alignment of maxillary dental arch must be achieved with minimal inclination and projection or even retro-inclination of anterior upper teeth. During a pre-surgical phase of 12 months, headgear bilateral force of 150 g/F was applied to the upper molars of a 22 years old male compliant patient with Class III skeletal malocclusion, to provide an upper teeth control of mesial tipping and projection during alignment and leveling. The ideal occlusal parameters required for surgical procedure were achieved without dental extractions permitting a total treatment period of 37 months. The outcomes remained stable over 3 years follow up after the removal of the appliance. The results indicate that, although headgear use depends greatly on patient compliance, when well indicated it is an interesting alternativetopromote dentaldecompensationon pre-surgical period, in order to allow surgical correction of skeletal Class III malocclusion.

Extração de incisivo inferior: uma alternativa no tratamento da classe III

The correction of a Class III malocclusion in adult patients is one of the major challenges in orthodontics due to facial deformities occurring during the unfavorable growth of this kind of pattern, as well as the treatment options capable of producing facial changes aesthetically acceptable and adequate for today's beauty standards. One acceptable alternative treatment is the removal of a lower incisor. For a Class III correction through a lower incisor extraction a thorough analysis and planning must be carried out by taking into consideration the amount of overjet and overbite, periodontal condition of the teeth and the possibility of obtaining a good dental occlusion with acceptable facial aesthetics. Will be presented two case reports of patients presenting an anteroinferior crowding, Class III malocclusion condition. The treatment through a lower incisor extraction and the reasons why this treatment was adopted will be discussed.

Avaliação da via aérea superior em pacientes classe III submetidos à cirurgia ortognática: revisão de literatura

Introduction: The configuration and dimensions of the upper airway are determined by anatomical structures such as soft tissues, muscles and craniofacial skeleton, composing or surrounding the pharynx. Anatomical abnormalities of the soft tissues and / or craniofacial skeleton may become more narrow upper airway. The orthognathic surgery, which is used in the correction of dentoskeletal deformities, also causes changes in the upper airway. Objective: In view of the facts presented, this article aims to review the literature on the changes of the upper airway in patients’ class III undergoing orthognathic surgery. Methodology: International Literature on Health Sciences (Pubmed ) and Port Journals CAPES original and review published between 1990 and 2010, in two bibliographic databases articles were selected. Results: thirty-nine (39) articles were selected for writing this review. Conclusion: The upper airway deformity and dental- skeletal class III should be carefully evaluated prior to orthognathic surgery and whenever surgical planning permit should prefer the maxillary advances to mandibular setbacks

Effect of platele-rich plasma on healing of class III furcation defects treated with autogenous bone grafting and guided tissue regeneration: a histomorphometric sutdy in dogs

Objective: The purpose of this study was to evaluate the effects of the platelet-rich plasma (PRP) when used in combination with autogenous bone graft and bioabsorbable membrane (Resolut® ) in the treatment of Class  III furcation defects in dogs. Material and method: Class III furcation defects (5 mm in height and in depth) were surgically created in the mandibular third premolars of five mongrel dogs. After nine weeks, the lesions were treated with scaling and root planning and each defect received one of the following treatments: autogenous bone graft + membrane (group C) or PRP + autogenous bone graft + membrane (group T). After a healing period of 90 days, the animals were sacrificed. Routine histological processing and staining with hematoxilyn and eosin and Masson trichrome were performed and a histomorphometric analysis determined the effect of the treatments on periodontal tissue regereneration. Data were analyzed by Hotelling’s T-squared (p < 0.05). Result: No statistically significant difference between C and T groups was observed by the histomorphometric analysis of the furcation area. Both treatment groups demonstrated similar regenerative results with the furcation defects partially filled and periodontal regeneration limited to the experimental notches of the lesions. (p > 0.05). Conclusion: According to the present results, PRP does not enhance the periodontal regeneration in class III furcation defects treated with autogenous bone graft and bioabsorbable membrane.
