Análise comparativa entre duas metodologias para aferição de infiltração por corante em apicoplastias com retrobturações

Different methodologies to verify the success of odontologic materials in apicoplasties with retro obturations have been used in marginal infiltration studies for courant. This research objectified to evaluate props up them of infiltration of Rodamine B 1%, in an experimental group, comparing it depth of penetration of the courante with its area of impregnation, in the same samples in apicoplasties with retro obturations. The results had demonstrated to a shunting line low standard (4,79), for the mensuration through the area, and high (15,05), for mensuration through the depth of penetration of the courante. The Mann-Whitney test shows significant statistical differences between groups (p<0,0001). The use of area impregnation instead of dye penetration represents a better way to measure levels of marginal infiltration considered in this research

Semiologia da articulação temporomandibular

The base for the diagnosis of cause and effect is an agreement of the normal form and its relation with the function. It can still be considered that if it does not find a riot in the function, without a corresponding degree of alteration in the structure. Therefore, and for the fact of that a basic knowledge of the sthomatognatic system starts with the joint to temporomandibular (TMJ), it is basic the structural and anatomical study of this structure. The TMJ is a set of anatomical structures that, with the participation of special muscular groups, they make possible to the mandible to execute varied movements during the chew. Biaxial complex is classified in the synovial category, having had as component anatomical the articulate surfaces, the articulate disc, the capsules, the ligaments, beyond the synovial membranes. The articulate surfaces are formed by a surface of the head of the mandible and by a surface of the articulate part of the temporal bone. The situations will be presented all here that the TMJ can be involved as the Anatomy, Physiology, Histology, Pathology, Examinations, Diagnosis, Diagnosis for image, Riots, Trauma and the Treatment

Análise de duas metodologias na aferição de infiltração por corante em apicoplastias com retrobturações

Different methods have been used in studies on marginalinfiltration caused by staining dye with the purposeof evaluating the efficiency of dental materialsemployed in apicoplasties with retrograde root filling.Apicoplasty consists of flattening the root apex eliminatingthe need of root amputation, maintaining its correctshape. The objective of the present study was toevaluate the results of infiltration of rhodamine B 1%in an experimental group, comparing the dye depth penetrationwith the impregnation area in the same samplesthat underwent apicoplasties with retrograde rootfilling. The samples included 12 human upper canineteeth endodontically treated and retro-obturated usingMTA. For sample analysis, the Image Tool® software wasused to perform computerized morphometry. Resultsshowed a low standard deviation (4.79) regarding areameasurement, and high standard deviation (15.05) interms of measurement of the dye depth penetration. TheMann-Whitney test showed statistically significant differencesbetween the groups (p < 0.0001). The use of thedye stained area, instead of dye depth penetration, provedto be a better choice for measuring marginal infiltrationscores according to the methodological parametersused in the present study

Tumor Benigno das Glândulas Salivares

Pleomorphic adenoma is a benign tumor with  higher prevalence in females in their 40s and 50s. It is characterized as an asymptomatic lesion mostly found in parotid glands followed by the minor salivary glands, mandibular glands, superior lip and jugal mucosa. It has a slow evolution, and intraoral tumors are mostly diagnosed when they start to interfere in mouth functions, such as masticatory activities, speaking, word pronunciations and deglutition. This paper shows three cases of pleomorphic adenomas found in the minor salivary glands of the hard palate and in the parotid gland with  different  therapeutic  procedures having been instituted and discussed. The clinical treatment was preferable in one of the cases  due  to  the  patient’s  systemic  condition. The other two cases were operated without any complication.O adenoma pleomórfico é um tumor benigno com maior prevalência em indivíduos do gê­nero feminino entre a quarta e quinta décadas de vida. É caracterizado como uma lesão assin­tomática, que acomete com mais frequência a glândula parótida, seguida pelas glândulas sa­livares menores, as glândulas mandibulares, o lábio superior e a mucosa jugal. É uma lesão de evolução lenta, sendo os tumores intraorais diagnosticados, na maioria dos casos, quando começam a interferir nas funções orais do pa­ciente, como mastigação, fala, deglutição e fo­nação. Este trabalho apresenta três casos de ade­nomas pleomórficos encontrados nas glândulas salivares menores do palato duro e na glândula parótida, com diferentes procedimentos tera­pêuticos sendo instituídos e discutidos. Em um deles, o tratamento clínico foi o de escolha, pois o paciente apresentava alterações sistêmicas gra­ves. Nos outros dois, a cirurgia para exérese da lesão foi realizada sem intercorrências

Intraoperative blood loss and blood transfusion requirements in patients undergoing orthognathic surgery

Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p < 0.05). Mean hematocrit values were 41.53 % preoperatively (range 31.3-50.0 %) and 36.56 % postoperatively (range 25-43.8 %) (p < 0.05). Mean blood loss was 274.60 mL (range 45-855 mL). Only two patients required blood transfusion. Although blood loss and transfusion requirements were minimal in the present study, surgical teams should monitor the duration of surgery and follow meticulous protocols to minimize the risks
