Um método para o retratamento da recidiva do desalinhamento dentário

INTRODUÇÃO: o ortodontista clínico deve esperar alguma perda do alinhamento dentário obtido durante o tratamento ortodôntico nos casos em que a contenção ortodôntica foi suspensa pelo profissional ou perdida pelo paciente. Nessa situação, os pacientes são, frequentemente, relutantes em novamente usar braquetes para retratar o alinhamento dentário perdido após o tratamento. OBJETIVO: esse artigo descreve o uso de uma técnica simples e eficiente para corrigir pequenas alterações do alinhamento dentário. Esse procedimento, inovador e de baixo custo, produz a resolução da recidiva em poucas semanas. A força usada para realinhar os dentes é obtida através de um fio elastomérico transparente amarrado a uma contenção fixa, de vários filamentos, colada às arcadas superior e inferior.

Neuropsychiatric symptoms in the prodromal stages of dementia

Purpose of reviewTo critically discuss the neuropsychiatric symptoms in the prodromal stages of dementia in order to improve the early clinical diagnosis of cognitive and functional deterioration.Recent findingsCurrent criteria for cognitive syndrome, including Alzheimer's disease, comprise the neuropsychiatric symptoms in addition to cognitive and functional decline. Although there is growing evidence that neuropsychiatric symptoms may precede the prodromal stages of dementia, these manifestations have received less attention than traditional clinical hallmarks such as cognitive and functional deterioration. Depression, anxiety, apathy, irritability, agitation, sleep disorders, among other symptoms, have been hypothesized to represent a prodromal stage of dementia or, at least, they increase the risk for conversion from minor neurocognitive disorder to major neurocognitive disorder. Longitudinal investigations have provided increased evidence of progression to dementia in individuals with minor neurocognitive disorder when neuropsychiatric symptoms also were present.SummaryAlthough neuropsychiatric symptoms are strongly associated with a higher risk of cognitive and functional deterioration, frequently the clinician does not acknowledge these conditions as increasing the risk of dementia. When the clinician accurately diagnoses neuropsychiatric symptoms in the prodromal stage of dementia, he could early establish appropriate treatment and, may be, delay the beginning of clinical and functional deterioration.

Avaliação da contagem plaquetária pelo contador automático QBC Vet Autoread comparado com estimativa em esfregaço sanguíneo e contagem em hemocitômetro

The platelet blood count in laboratorial routine provides to the clinician important information about the hemostasis of the patient. There are many techniques described, however the gold standard techniques realized in hemocytometer spent a lot of time, making this technique impracticable in great routines. This research had the intent to evaluate if the automatic veterinary blood counter QBC Vet Autoread (R), whose results get five minutes to be ready, is capable to offer a trustworthy platelet count number. To this end, were evaluated the correlations among three different forms of platelets count in dogs: count in automatic blood counter QBC Vet Autoread (R), estimative in blood smear and the gold standard method by manual count in hemocytometer. The viability and confidence use of automatic blood counters of the medicine veterinary routine. Seventeen dogs were chosen randomly way, in the medical and surgical routine of HOVET-USP. The analysis revel high correlation between the hemocytometer and the estimative in blood smear (r=0,875) and between the hemocytometer and automatic blood count by QBC Vet Autoread (R) (r=0,939). Conclude that the platelet blood cont by QBC Vet Autoread (R), in addition to be fast, it's more truthful when compared with estimative in blood smear, although the latter one also had elevated correlation. However, morphological analysis through the smears cannot be dismissed because none of the other two techniques evaluated have the ability to assess platelet morphological changes.

Cuidados essenciais e muitas vezes negligenciados na hospitalização de pequenos animais: nutrição e analgesia

The benefits of proper nutrition and analgesia are closely linked when it comes to animals that are suffering from any illness and are hospitalized. In patients who are ill or under the stress of hospitalization, increase secretion of glucagon, catecholamines, cortisol and growth hormone antagonize the effects of insulin, leading to hyperglycemia and degradation of tissue proteins to provide substrate for gluconeogenesis. These changes result in loss of lean body mass, reflecting negatively on tissue repair processes, immune response and prognosis. Likewise, the pain induced by noxious stimulation can lead to protein catabolism, stress, immunosupression, delayed wound healing and acceleration of disease processes. This review confirms the nutrition and pain control importance in hospitalized patients, showing their physiological benefits and reduction in hospital stay when the clinician understands these benefits and the animals are treated with such care

Os efeitos do lupus eritematoso sistêmico no sistema urinário de pequenos animais

Systhemic lupus erythematous is a imunomediated disorder witch affects primarly dogs between two and nine years. Clinical manifestations are very diverse, including renal signs, that may lead to chronic renal disease, and dermatologic and joint sings. Systhemic lupus erythematous diagnostic is a challange to the clinician, due to its diverse list of differecial diagnoses and its low availability of specific tests. The treatment consists of corticosteroids and imunomodulators, and supportive therapy that inhibits the progression of the disease. Monitoring the animal with systhemic lupus erythematous is important, due to its recurrent caracteristic

Otimização do tracionamento de canino impactado pela técnica do arco segmentado: relato de caso clinico

Upper canines impaction are considered the second most frequent and are associated to important esthetics and functional limitations. Among the treatment strategies described in the literature the most commonly used are the extraction of the primary canines and the surgical exposure followed by orthodontic traction, that requires an adequate interdisciplinary approach. The aim of this case report is to draw the attention of the clinician to the possibility of adapting the segmented arch technique to manage a canine impaction clinical case.

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.

Associação da raspagem com antibioticoterapia em um caso de periodontite agressiva generalizada

The treatment of aggressive periodontitis is a challenge to the clinician, therefore the search for effective treatment protocols of this disease is important. The aim of this case report was demonstrate the effectiveness of the combination of systemic antibiotics with non-surgical periodontal therapy in the treatment of generalized aggressive periodontitis. a 27-year-old patient (RCS), smoker for 11 years (10 cigarettes/day on average), with no systemic alteration, attended the periodontal clinic with a complaint abnormal dental position. After the clinical examination, the diagnosis of generalized aggressive periodontitis was defined. The non-surgical periodontal treatment was executed associated with administration of amoxicillin plus metronidazole for ten days. Clinical parameters (Clinical Attachment level, marginal gingival level, periodontal probing depth, bleeding on probing, plaque index and gingival index) and radiographic parameters (distance between the cemento-enamel junction and the bone crest) were evaluated before and after non-surgical periodontal treatment, after antibiotic therapy and three, six and 12 months after the treatment. After one year follow-up, the results showed improvement in clinical and radiographic parameters with stabilized and decreased tooth mobility and absence of tooth loss. It was concluded that the association of non-surgical periodontal therapy with the administration of amoxicillin/metronidazole was effective in the treatment of generalized aggressive periodontitis.

Interação entre odontologia restauradora e periodontia - parte 2: reanatomização dentária

The development of new dental materials has expanded dental therapeutic modalities ensuring excellence in aesthetic restorative treatments. Thus, the direct restorative procedures have been used in cases of dental reconstruction allowing an effective treatment with a low cost, while preserving healthy tooth structure. However, the clinician must be used to the techniques and the material in order to ensure longevity and success in the direct restorative procedure. The aim of this paper is to descrive, after completion of periodontal surgical procedures, the direct restorative step performed for dental reconstruction and diastema closure. The integration between Restorative Dentistry and periodontics enableb the restoration of a harmonious smile in a conservative manner, ensuring aesthetics and patient stisfaction.

Methods for removal of resin remaining after debonding of orthodontic brackets: a literature review

The removal of resin debris and/or resin cement from the enamel surface without causing iatrogenic is the main objective when removing the orthodontic brackets. Some factors such as the time required for removal, damage to the tooth structure, are essential factors for the clinician at the time of removal. Various techniques are used for the removal of orthodontic brackets after the treatment; it is known that the use of clinical procedures such as the use of diamond burs and some pliers removers can damage the structure of the enamel, often depending on the bond strength that should be taken into consideration at the time of removal. This literature review aims to gather the most relevant studies that can clarify the clinical technique, which may be more suitable for removal of the brackets.

Cherubism: clinicoradiographic features and treatment

Cherubism is a congenital childhood disease of autosomal dominant inheritance. This disease is characterized by painless bilateral enlargement of the jaws, in which bone is replaced with fibrous tissue. The condition has sui generis clinical, radiographic and histological features, of which the clinician should be aware for a better differential diagnosis in the presence of a fibro-osseous lesion affecting the bones of the maxillomandibular complex. The purpose of present paper was to review the literature and to report the most important aspects of cherubism in order to facilitate the study of this disease. Literature was reviewed about cherubism, emphasizing the relevant clinicoradiographic features and treatment. Literature was selected through a search of PubMed and Scielo electronic databases. The keywords used for search were adolescent, cherubism, cherubism/physiopathology, cherubism/treatment, cherubism/radiography. A manual search of the reference lists of the identified articles and the authors' article files and recent reviews was conducted to identify additional publications. Those studies that described new features about cherubism were included in this review. In total 44 literature sources were obtained and reviewed. Studies that described new features about cherubism physiopathology, diagnostics and treatment were reviewed. Despite the exceptions, cherubism is a clinically well-characterized disease. In cases of a suspicion of cherubism, radiographic examination is essential since the clinical presentation, the location and distribution of the lesions may define the diagnosis. Histopathological examination is complementary. Nowadays, genetic tests should be used for final diagnosis of cherubism.

Higienização em prótese sobre implante

With the advances of osseointegration principles, the use of implant-supported prosthesis has become a routine treatment option. The success of an implant is initially associated to the surgical technique, primary stability and absence of bacterial contamination on the implant site. Subsequently, the absence of mechanical trauma (overload) and peri-implantitis are sine qua non conditions to the longitudinal success of implant treatment. Therefore, the strict maintenance of oral hygiene is highly important to avoid biofilm accumulation around the implant and consequently to provide last-long implant-supported dentures. The clinician has the responsibility to supply a favorable prognosis to the patient so that the rehabilitation succeed. For this reason, during prosthesis fabrication the clinician should observe the design and emergency profile of the prosthesis, the peri-implant sulcus depth as well as the presence of motor or psychological impairment by the patient. Subjects with missing teeth and that will be submitted to the implant treatment should be motivated and adequate instructed regarding oral hygiene and its importance since the best option to obtain treatment longevity and consequently patient’s satisfaction is the prevention. Therefore, this study aimed to perform a literature review about the hygiene of implant-supported prosthesis.
