Estudo comparativo de dois programas de computador (Dolphin Imaging e Nemotec) versus o método manual utilizados para análises cefalométricas de pacientes com deformidade dento-facial padrão II

A-Nperp, Pg-Nperp e mandibular plane). Thirty patients (male or female), with age varying from 19 to 48 years old were analyzed. All patients were diagnosted with mandibular retrognathism and submitted to bilateral sagital mandibular advancement. All tracings were performed in lateral cephalometric radiographs obtained one week before surgery. The intraclass correlation coefficient analysis (ICC), the t test adjusted for Tukey-Kramer test and Schuirmann test were applied. The results showed that the manual tracings and Nemotec® tracing had excellent reliabilities for all measures (ICC > 0.98). The Dolphin Imaging® showed low reliability in anterior facial height (value of ICC = 0.70), Co-A (value of ICC = 0.47) and Co-Gn (ICC value = 0.49). In A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB there were no differences between the 3 tracings (p > 0.05), for the anterior facial height measures differences were found between the Dolphin Imaging® and Nemotec® tracings, but no differences were observed as compared to the manual tracing (p > 0.05), in Co-A and Co-Gn measures t Dolphin Imaging® presented a significantly lower mean than the other methods (p > 0.05). The manual tracings were equivalent in 6 of 8 measures (A-Nperp, Pg-Nperp, md Plan, SNA, SNB and Co-A), there was no equivalence between the methods in the anterior facial height and Co-Gn measures (p < 0.01). The Dolphin Imaging® method was not equivalent in any of the 8 measures. It was concluded that in the manual tracing only the Co- Gn, Pg-Nperp and SNB measures confirmed the diagnosis of mandibular retrognathism, and the Nemotec® software showed better results than the Dolphin Imaging® software.

Efeitos dentoesqueléticos do tratamento da classe II utilizando o aparelho de Herbst associados à mecânica Straight-wire

This study compared the effect of the treatment protocol for correcting Class Il malocclusion using the Herbst appliance followed by full fixed Straigh-wire mechanics, in two populations, one Brazilian and one of North American origin As a untreated control sample the data from the University of Michigan Elementary and Secondary School Growth Study (UMGS) was used. Our sample was composed of 12 males and 12 females, with initial mean age of 12 years 7 months and final mean ages of 15 years and 3 months. The Michigan patients comprised 21 females and 7 males, with an initial mean age of 11 years and 9 months and final mean age of 14 years and 4 months. The control sample was paired in number, sex and age to the treated Michigan sample. ln both treated groups, lateral cephalometric radiographs were obtained before the Herbst appliance was cemented and at the end of the fixed appliance phase, The first comparison involved the Brazil group and the untreated controls, which demonstrated that the association of the Herbst appliance followed by fixed Straight-wire appliances provoked positive effects on the dentofacial complex, improving pre-existing maxillo-mandibular relationships, besides increasing dentoalveolar compensations which contributed to correct the malocclusion. The second comparison, involved the Brazl1ian and North-American patients treated with the same protocol. Although the pre-treatment comparison showed that the two groups were not similar in all aspects, they presented almost identical therapeutic modifications, which indicate that the effect of' treatment was very similar. These results point out that, in Class ll treatment, the combination of Herbst/Straight-wire mechanics produce consistent and systematic effects, correcting or minimizing possible skeletal imbalances

Efeitos do aparelho de Herbst no tratamento proecoce da má oclusão classe II de Angle

Due to its high prevalence in general population, Angle Class II malocclusion has been widely studied by several authors, as well as the methods for its treatment. Among the possible treatment methods stands out the Herbst appliance. Reintroduced more than three decades ago in the orthodontics community, it became the most utilized appliance because it does not require patient compliance, and provides continued action through bilateral telescopic tubes. The objective of the present article was to demonstrate the early treatment of Class II Division 1 malocclusion with mandibular retrusion using Herbst appliance.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

Interactions between restorative dentistry and periodontics: luting post nonmetallic (Part II)

Endodontically treated teeth have necessary use of intracanal posts. Due to the constant need and search for esthetic materials with properties similar to tooth structure remaining fi berglass posts esthetic came good these shortcomings and are increasingly used as a fi rst option for prosthetic rehabilitation. In this case report is described step by step how to perform the cementation of a nonmetallic post and core construction for making a piece prosthetic onlay in a simplifi ed way, by choosing the self-etching cementation technique.

Synergist interaction between angiotensin II and DOCA on sodium and water balance in rats

Blockade of central angiotensin receptors with the specific antagonist [Leu8]-ANG II abolished water ingestion and water and sodium excretion induced by infusion of angiotensin II (ANGII) into the lateral ventricle (LV) of rats. The antagonist reduced but did not suppress the salt appetite induced by ANGII infusion. Subcutaneous injection of deoxycorticosterone acetate (DOCA) caused increases in water and 3% NaCl ingestion and decreases in sodium excretion. When central ANGII infusion was combined with peripheral DOCA, the water intake was similar to that induced by ANGII alone and the ingestion of 3% NaCl was increased, whereas sodium excretion was inhibited. When ANGII was infused alone, a detailed temporal analysis of fluid and sodium balance showed a negative balance similar those saline controls that persisted throughout the experiment. Combined administration of ANGII and DOCA induce significant changes in water and sodium balance. Sodium and water maintained a positive balance through out the 8-h experiment. The data support an interaction of central ANGII and DOCA on sodium intake and water and sodium balance. © 1994.

Effect of furosemide treatment on the central and peripheral pressor responses to cholinergic and adrenergic agonists, angiotensin II, hypertonic solution and vasopressin

The present study was performed to investigate the effect of treatment with furosemide on the pressor response induced by intracerebroventricular (i.c.v.) injections of cholinergic (carbachol) and adrenergic (norepinephrine) agonists, angiotensin II (ANGII) and hypertonic saline (HS, 2 M NaCl). The changes induced by furosemide treatment on the pressor response to intravenous (i.v.) norepinephrine, ANGII and arginine vasopressin (AVP) were also studied. Rats with a stainless-steel cannula implanted into the lateral ventricle (LV) were used. Two injections of furosemide (30 mg/kg b.wt. each) were performed 12 and 1 h before the experiments. Treatment with furosemide reduced the pressor response induced by carbachol, norepinephrine and ANGII i.c.v., but no change was observed in the pressor response to i.c.v. 2 M NaCl. The pressor response to i.v. ANGII and norepinephrine, but not AVP, was also reduced after treatment with furosemide. These results show that the treatment with furosemide impairs the pressor responses induced by central or peripheral administration of adrenergic agonist or ANGII, as well as those induced by central cholinergic activation. The results suggest that the treatment with furosemide impairs central and peripheral pressor responses mediated by sympathetic activation and ANGII, but not those produced by AVP. © 1992.
