The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.

This study focused on the validation of the Spanish version of the UNESP-Botucatu multidimensional composite pain scale to assess postoperative pain in cats. The original scale in Portuguese was translated into Spanish by two independent translators, and summarised in one version by a third individual. The summarised version was back-translated and minor adjustments were made. The scale was reviewed by three anesthesiologists with Spanish as their first language, and the final version was submitted to psychometric testing. Thirty cats undergoing ovariohysterectomy were video recorded during the perioperative period. Six observers from different spanish speaking countries, who had Spanish as the first language watched the videos and determined the pain scores using the Spanish version of the scale, identifying the cats that should receive analgesics. Videos were reanalysed in a different order about 2 months after the first assessment. The sensitivity to change, content and construct validity were established by the significant change in pain scores in response to surgery and analgesics. The agreement between the evaluations of the 'gold standard'(researcher that developed the scale) and the other observers confirmed the criterion validity. Inter- and intra-rater reliability, evaluated by intra-class correlation coefficient, ranged from good to very good for all scale items. The cut-off point for rescue analgesia identified by Receiver Operating Characteristic curve was > 7 with 92% of sensitivity and 91% of specificity. The Spanish version of the UNESP-Botucatu multidimensional composite pain scale is interpretable (has an optimal analgesic intervention score), valid and reliable instrument for assessing acute pain in cats undergoing ovariohysterectomy.

The indications for adenotonsillectomy in pediatric patients have changed considerably during the 90th decade. Local or systemic complications of the adenoid or tonsil hypertrophy itself have now been substituted by signs of obstructive ventilatory disturbances, including obstructive sleep apnea as the major indications for surgery. Objective: This study analyses the clinical profile of children submitted to adenotonsilectomy in their pre and postoperative state, at Botucatu Medical School-State University São Paulo, UNESP. Methods: 332 children of both genders, aged 1 to 12 years, who underwent adenotonsillectomy between 1999 and 2004, were studied, focused on epidemiological profile, pre and postoperative (1 month) symptoms, obtained from medical records. Height and weight were compared to brazilian normal age related values. Results: We found a predominance of the male gender, except in he group aged from 10 to 12 years. Considering wheight and height, we found important failure to thrive, mostly for height deficit. Among clinical aspects, we found a significant reduction in obstructive symptoms like snoring or apneia (p<0001) in the postoperative period. Conclusion: Our results were similar to the literature findings of patients clinical profile. The major indication for adenotonsillectomy in our service was clinical diagnosis of obstructive sleep apnea.

Cats are gradually occupying a more important position as pets and this preference is a result of how easy cat maintenance in an urban environment is, even though they are very prolific and need surgical sterilization. This paper aims at evaluating obtained data within 15 years of research in a university service program that offers free cats sterilization surgery. We carried out a statistical analysis of data shown in the records of animals treated by the program. Surgical sterilization was performed on 647 animals (409 females – 63% and 238 males – 37%). Unilateral cryptorchidism was observed in 9 (3.8%) male cats. Forty (10%) female cats were pregnant at the time of the surgery and the treatment with contraceptives was observed in 67 (16.4%) female cats. One death occurred during anesthesia recovery and 2 cats were euthanized because of wound infection, totalizing an amount of 0.5% of severe complications. From 1996 to 2004, 212 female cats were spayed (122 adults and 90 prepubertal) and during that time two different approaches for ovariohysterectomy were compared: flank laparotomy and ventral midline celiotomy. The flank laparotomy approach was used in only 46 female cats (21.7%) due to some disadvantages observed – the need of an incision on each flank in prepubertal or nulliparous animals and the difficulty or impossibility of total uterus removal. In the same period, 105 male cats underwent orchiectomy via an open technique in which the spermatic cord was linked with nylon thread. From 2005 to 2010, 197 females (106 adults and 91 prepubertal) were spayed. The minilaparotomy technique was used to perform ovariohysterectomy on 139 female cats (70.6%). In this procedure, ovaries and uterus were exteriorized in a blind fashion with a hook through a small midline incision. The traditional midline ovariohysterectomy, which incision length permits direct visualization of the ovaries and uterus, had to be performed in 58 (29.4%) female cats due to advanced pregnancy, full urinary bladder during surgery or obesity. Over the past 6 years, 133 male cats (48 adults and 85 prepubertal) were castrated by means of an open technique in which the spermatic cord was tied to itself. The demand for surgeries during the project demonstrated that people are becoming aware concerning the importance of sterilization when facing cat overpopulation and abandonment.

Many incisions have been described for approaches to zygomatic fractures. Precise repositioning of zygomatic complex fractures is difficult. The traditional approach is through an eyebrow incision, but it can produce a scar that causes aesthetic and psychological problems for the patient. We describe the supratarsal fold approach to expose the frontozygomatic suture and to reduce small displacements of frontal sinus anterior wall; it gives good access and excellent aesthetic results.

This work aimed to analyze clinically and histologically the allogen bone graft behavior at 6 and 9 months. A leukoderm, female, 55 years old patient sought dental care for oral rehabilitation with dental implants and implant supported fixed prosthesis in the maxilla. Bilateral sinus lifting procedure were performed in a same patient, the analysis were made after 6 and 9 months, respectively. At 6 months, there was lack of a better bone remodeling in the region, associated to the presence of fibrous connective tissue within the collected tissue, showing us that this is not the best stage of tissue maturation to place dental implants. The 9 months period showed an improvement, with a more organized bone tissue surrounding particles of homogenous bone, what possibly had increased implant stability at the time of surgery. There is no doubt about the increase of clinical applications of FFBA, but there are no studies available regarding the standardization of time to load implants inserted in allografts. So papers with long-term monitoring are necessary to eliminate questions that still remain to be answered.

Class III malocclusion is less common occlusal relationship, covering less than 5% of the population. There are various forms of treatment in Class III malocclusion. Depending on how the form is expressed Class III and age of the patient, the therapy may be orthopedic and orthodontic surgical orthodontics. The objective was to review the literature of the last 10 years about ways to compensatory treatment of Class III malocclusion. Several articles were published between 04/2003 and 04/2013 in the Pubmed database from the keyword "Class III malocclusion". However, only 19 articles that addressed the compensatory treatment of Class III were selected. Based on the selected items it was concluded that the treatment of Class III malocclusions in children before the peak of pubertal growth has better prognosis with greater effects orthopedic and orthodontic minor effects. The ideal treatment option for this condition is the Rapid maxillary expansion associated with maxillary protraction of the same. The treatment of Class III malocclusion in young people after the peak of pubertal growth is doubtful prognosis. You can opt to treat rapid maxillary expansion and maxillary protraction of the same or fixed appliance, however, orthopedic effects can be the same or smaller than the orthodontic effects, depending on the age of the patient. Depending on the degree of Class III malocclusion in adults, the treatment will consist of dental compensations or orthognathic surgery.

In order to evaluate the quality of life of patients with head and neck cancer, this study analyzed data of 24 patients with squamous cell carcinoma, which indicated therapy was radiotherapy or not be combined with chemotherapy and surgery. The study was conducted in the Unit of Radiotherapy of Megavoltage located in the São José de Rio Preto-SP, in the period August 2007 to January 2008. Then, it was used the questionnaire of quality of life from University of Washington which enabled the identification of different quality of life patterns associated with the different stages of radiotherapy, indicating to be viable the prospect of recognition of prognostic factors of reduction in multiple domains of quality of life. From the data collected and analyzed, it was identified that the areas with the worst score in the begin of radiotherapy were appearance, speech and anxiety; during the treatment were taste, saliva and anxiety; and in the end were taste, saliva and swallowing. Throughout the treatment, it was observed the deterioration of patients' mood. In this regard, emphasizes the importance of dental and psychological follow-up, within the framework of a multidisciplinary care for patients with head and neck cancer during radiotherapy treatment.
