Use of Bichat’s buccal fat pad for the sealing of orosinusal communications. A presentation of 8 cases

Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusalcommunications, describe the surgical technique used, and report the main complications.Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the Universityof Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem.Results: All of the orosinusal communications were successfully resolved with this technique. The immediatepostoperative complications were pain (37.5%), inflammation (37.5%), edema (32.5%), trismus (37.5%), halitosis(14.3%), suppuration (12.5%) and rhinorrhea (12.5%).Conclusions: The use of Bichat’s buccal fat pad is not regarded as the technique of choice for sealing small tomedium sized orosinusal communications. However, in the case of large communications, it is a good option, andthe results obtained are optimum (AU)

Complications of guided surgery and immediate loading in oral implantology: A report of 12 cases

Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheseswith immediate function, have led to the development of software capable of planning and manufacturing a surgicalguide and prosthesis that can be placed upon conclusion of the implant surgery step.The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgerytechnique, together with patient comfort during and after treatment.Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulousupper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned andoperated upon with the guided surgery technique.Results: A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complicationscomprised a lack of primary stability, while the postoperative complications consisted of infections and a lack ofimplant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of theprovisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. Thedegree of patient satisfaction was evaluated using a verbal scale.Conclusions: Implant restoration with the guided surgery technique and immediate functional loading is a predictableprocedure, provided patient selection and the surgical technique are adequate, affording lesser postoperativemorbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and function (AU)

In vitro evaluation of the temperature increment at the external root surfaceafter Er, Cr: YSGG laser irradiation of the root canal

Objectives. A study was made to determine the temperature increment at the dental root surface followingEr,Cr:YSGG laser irradiation of the root canal.Design. Human canines and incisors previously instrumented to K file number ISO 30 were used. Irradiation wascarried out with glass fiber endodontic tips measuring 200 ¥ìm in diameter and especially designed for insertionin the root canal. The teeth were irradiated at 1 and 2 W for 30 seconds, without water spraying or air, and applyinga continuous circular movement (approximately 2 mm/sec.) in the apico-coronal direction.Results. At the 1 W power setting, the mean temperature increment was 3.84¨¬C versus 5.01¨¬C at 2 W. In all casesthe difference in mean value obtained after irradiation versus the mean baseline temperature proved statisticallysignificant (p< 0.05).Conclusions. Application of the Er,Cr:YSGG laser gives rise to a statistically significant temperature increment atthe external root surface, though this increment is probably clinically irrelevant, since it would appear to damagethe tissues (periodontal ligament and alveolar bone) in proximity to the treated tooth (AU)

Pesquisa del cancer colorrectal con una prueba inmunológica para sangre oculta en material fecal / Screening for colorectal cancer with an inmunological fecal occult blood test

La pesquisa del cáncer colorrectal (CCR) no se realiza rutinariamente en nuestro medio a pesar de las recomendaciones internacionales. Por ese motivo decidimos realizar un estudio piloto evaluando un método inmunológico de detección de sangre oculta en materia fecal (SOMF). Se estudiaron 332 pacientes con riesgo promedio para CCR (>50 años, sin signos y síntomas ni antecedentes personales a familiares de CCR) que concurrieron a consultorios de clínica médica de Buenos Aires. Fueron dispostos al aza para la pesquisa de SOMF (OC-Hemodia) con una (grupo I) o tres (grupo II) determinaciones. A los pacientes con una o más muestras positivas se les indicó una fibrocolonoscopia y/o radiología de colon por enema y una endoscopía digestiva alta. Devolvieron la muestra 141 de los 162 pacientes del grupo I (87.0 por ciento) y 142 de los 170 del grupo II (83.5 por ciento) (NS). En el grupo fueron positivas 3 de las 162 muestras entregadas (1.8 por ciento) y en el grupo II 15 de las 170 (8.8 por ciento) (P=0.005), con una positividad global del 5.4 por ciento. Se estudio radiologicamente el colon en 14 pacientes (77.8 por ciento) y 4 concurrieron a la consulta tras repetidos llamadas. El estudio colónico mostró: CCR 1, adenomas colónicos 3, adenomas colónicos y hemorróides 1, divertículos 5, hemorroides 1, normal 2, estudio frustrado por intolerancia 1. Se realizó una endoscopía alta a 9 pacientes: gastrite erosiva 4, úlcera duodenal 1, normal 4. Sólo 1 paciente tuvo ambos estudios normales. Concluimos que: 1) La prueba inmunológico para SOMF tuvo una tasa de aceptación y de positividad aceptable para la pesquisa del CCR. 2) Aún con un método inmunológico se requirieron tres muestras para mejorar su rendimento. 3) Detectó patología alta o baja del tubo digestivo, incluídos CCR y adenomas, en casi todos los casos estudiados. 4) Se justifica su implementación en estudios poblacionales amplios destinados a ver la eficacia en la prevención de CCR.
