Fístula infraorbitária associada à doença periodontal em cães

Veterinary Dentistry has grown considerably in recent years. This growth, associated to increase of knowledge among pet owners regarding responsible ownership of their pets, resulted in growing concern about the oral health of the animals that already can be observed at veterinary clinics. Among the oral diseases in dogs, infraorbital fistula, so called carnassial” fistula, is a periapical osteolytic lesion of the fourth premolar (4 SPM), often associated with periodontal disease. In its early stages, is characterized clinically by a swelling in the region of the jawbone before the formation of the fistula and leakage of a liquid serosanguineous or purulent secretion. Because of these clinical features, it is often misdiagnosed as a skin condition unrelated to the teeth. It is very important to obtain intraoral radiographs to confirm the diagnosis for performing the most appropriate treatment, according to the cause of the injury

Avaliação da prevalência do tipo de crescimento crânio facial nas diferentes más oclusões, de acordo com a classificação de angle

During the orthodontic correction planning in addition to dental-jaw correction, facial aesthetics is the orthodontist's and patient's major concern. To prevent facial aesthetics damage is really important to take into account the type of craniofacial growth: mesofacial (balanced), dolichofacial (vertical) or brachyfacial (horizontal). We evaluated 152 documentation files from the Department of Orthodontics of Dental University of Sao Jose dos Campos- UNESP in order to analyze what kind of growth occurs in most Class I malocclusions, Class II and Class III Angle of treated individuals from 6 to 12 years old. From the randomly collected samples, 15 of them belonged to Class I Angle malocclusions; 123 belonged to Angle Class II and 14 to Class III malocclusion. The results showed that in Class I, 66.67% were classified as dolicocephalic; in Class II, 64.23% were classified as dolicocephalic and in Class III, 50% were brachycephalic. We conclude that the dolichofacial was the type which ocurred the most, both in females and males and both in malocclusion Class I and Class II. The brachyfacial type most occurred in Class III malocclusion and the mesofacial type occurred in smaller numbers in the three malocclusions studied

Chauliocheilos saxatilis, a new genus and species of Hypoptopomatinae from rio Jequitinhonha basin, with a unique labial appendix (Teleostei: Loricariidae)

Chauliocheilos saxatilis, new genus and species, is described from headwater streams of the rio Itamarandiba, upper rio Jequitinhonha basin, southeastern Brazil. The new genus is diagnosed from all other Loricariidae members by having a unique labial appendix at laterodorsal portion of lower lip, associated to the proximal region of insertion of the maxillary barbel. From all Hypoptopomatinae genera, Chauliocheilos can be distinguished by having two additional series of lateral plates, one between the dorsal and mid-dorsal series, and the other between the mid-ventral and ventral series. In addition, the great number of lateral plates, the absence of the iris operculum, and the posterior dorsal-fin insertion contacting the neural spine of eighth vertebra, are other useful features to recognize the genus. The phylogenetic position of Chauliocheilos among the Hypoptopomatinae, as well as the morphology and possible functions of the labial appendix, are discussed.

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.

Tratamento da classe II hiperdivergente com o aparelho extra bucal de Thurow modificado

Objectives: natural dentofacial changes and that induced by the Thurow modified extra oral appliance (TMEOA) were evaluated in this prospective study. Methodology: the data consisted of fifteen Class II division 1 children 7 to 10 years old, with anterior open bite and hiperdivergent facial pattern treated with the Thurow appliance and of fifteen Class II division 1 children followed longitudinally from 6 to 12 years of age without treatment (Burlington Growth Centre, Toronto University, Canada). The analyses were based in traditional measurements obtained in lateral cephalometric radiographs scanned with the aid of the software Radiocef Studio®. Radiographs were taken in the beginning and after 1 year of treatment for the treated group and at the 6, 9 and 12 years of age for the control group. Results: the data analysis showed that the TMEOA significantly reduced the SNA, ANB, AOBO, SNPOc SNPM, SGO/NMe, OJ e OB. On the other hand the appliance did not interfere with the SNB e SNPP. The natural growth promoted significant change in the ANB, AOBO, SNPOc, OJ e OB from 6 to 9 years and in the SNB, SNPOc e SGo/NMe from 9 to 12 years. The restriction of the maxillary growth (SNA), reduction of the skeletal discrepancy (ANB) and the reduction of the overjet (OJ) were significant with the treatment considering the natural growth as verified in the control group. Conclusion: the TMEOA corrected the skeletal Class II malocclusion by maxillary restriction, reducing the overjet, closing the anterior open bite and decreasing both the hyper divergent facial pattern and mandible plane inclination.

Reaproveitamento imediato da ação expansora em um caso de expansão rápida da maxila assistida cirurgicamente

Immediate reutilization of the expanding action in a case of rapid maxillary expansion surgically assisted. The orthopedic rapid maxillary expansion (RME) and rapid maxillary expansion surgically assisted (RMESA) are conducted with the aim of giving an appropriate jaw, capable of providing a normal occlusion. In extreme cases, where there is a severe atresia, it is necessary to perform an expansion beyond that allowed by the expander, followed by another conventional device or a butterfly expander, when the atresia is in the anterior maxillary region. In this situation, there are two options: wait about 90 days to allow intermaxillary suture restructuring and perform a new RME / RMESA or proceed immediately to the expansion process. Considering the biological cost, financial and clinical time, the procedure of reusing the immediate expander action becomes the technique of choice in these cases, been the operational procedure performed simplified and in just four steps. This work will show a case report where, after accomplishing the RMESA was observed that even after changing the shape of the maxillary arch, the severity of atresia could not be corrected, especially in the anterior region, and more expansion was needed. Aiming to correct the atresia in the anterior maxilla, the technique used was to reuse the immediate expander action through the change of an intraoral screw expander for a conventional butterfly type screw expander.

Alterações dentoesqueléticas verticais e horizontais induzidas pelo ativador elástico Aberto de Klammt

The aim of this study was to evaluate the vertical and horizontal dentoskeletal changes induced by the Klammt Open Elastic Activator in the treatment of the Class II Division 1 malocclusion. The sample of 34 children was divided into two groups of 17 subjects each (ten girls, seven boys), matched by age and gender and with an initial mean age of 8.5 years. The data was analyzed using a Student's t-test for intragroup and intergroup comparison. The results showed that the appliance promoted dentoalveolar restriction of the maxilar growth within normal anteroposterior and vertical growth of the maxillary apical base; increment in the vertical displacement the mandibular symphysis associated with normal horizontal growth of the mandible; palatal tipping of the upper incisors; restriction of the anterior migration of the upper molars; greater eruption pattern and normal anterior displacement of the lower incisors and molars. It was concluded that Klammt appliance induce changes that are predominantly horizontal dentoalveolar in upper arch and vertical dentoalveolar in lower arch and vertical skeletal changes in the mandible.

Alterações dimensionais em pacientes submetidos à expansão rápida da maxila com aparelho do tipo Haas

The maxillary atresia is a alteration in the transverse dimension that can result in a unilateral or bilateral crossbite. For correction of atresia of the upper dental arch appliances with the intent to expand the arch of orthopedic or orthodontic manner are used, obtaining across-compatibility between the dental arches. The purpose of this study was to evaluate the dimensional changes of the maxillary in patients in the mixed dentition with atresia in the upper dental arch, using occlusal radiographs taken before, after rapid maxillary expansion and after removal of the appliance. Methods: the sample consisted of 35 patients who used the appliance type conventional Haas, in the mixed dentition, according to the standard protocol for installation, activation, containment and removal of the appliances rapid maxillary expansion. Results: the results confirm that the suture opening occurs in greater quantities in the anterior (4.3 mm) than posterior to (3.74 mm), representing a triangular opening of 7 degrees on average with the posterior opening 87% of the quantity of anterior opening. The molars region expanded about 5 mm, and the base bone 3.7 mm, representing a 74% bone expansion of the expansion teeth.
