Paraendodontic surgeries have been increasingly used to solve problems related to failures in conventional endodontic treatment. Better anatomical knowledge of the structures as well as the development of techniques and materials involved has resulted in substantial paraendodontic surgery increase and success. In some cases, teeth endodontic treatment highly benefits treatment accomplishment. This report describes a case of an endodontic treatment complemented by paraendodontic surgery in periapical region of 21, 22 and 23 of a female patient who had been treated at the clinic of the Brazilian Dental Association Dentistry - in the city of Cascavel, State of Parana, Brazil. The case presents a 12-month follow-up for the resolution of painful symptoms, lesion reduction, and bone formation. Literature review was performed regarding paraendodontic surgery in order to assess the determining factors, failure causes and procedure indications/contraindications, as well.
Longos períodos de imobilização conduzem à perda óssea e de propriedades do osso, e sua recuperação depende de vários fatores; além disso, a imobilização pode causar ulcerações no tecido cartilaginoso articular devido a alterações como perda de proteoglicanas, de massa e volume totais da cartilagem. O objetivo deste estudo foi verificar alterações histológicas, do tecido ósseo periarticular e da cartilagem articular, provocadas pela imobilização e remobilização de membros posteriores de ratos Wistar. Foram utilizados 12 ratos Wistar, divididos em dois grupos: GI -(n = 6): 15 dias com o membro posterior esquerdo imobilizado em plantiflexão, sendo o membro direito o controle; GR -(n = 6): período de 15 dias de remobilização livre na gaiola, associado a três séries diárias de alongamento do músculo sóleo esquerdo por 30 segundos. Foram avaliados no tecido ósseo as medidas de espessura do osso cortical, diâmetro do canal medular e número de osteócitos; no tecido cartilaginoso, foram mensurados a espessura média da cartilagem e o número de condrócitos. Como resultado, observou-se que para GI não houve alterações significativas na espessura do osso (p = 0,1156) nem no diâmetro do canal medular (p = 0,5698), mas diminuição significativa dos osteócitos em relação ao contralateral (p = 0,0005); em GR também houve decréscimo no número de osteócitos (p = 0,0001), mas as diferenças na espessura (p = 0,1343) e diâmetro do canal medular (p = 0,6456) mantiveram-se não significantes. Para os dados de cartilagem articular não houve diferenças significativas para as amostras, tanto na espessura da cartilagem para GI (p = 0,6640) e GR (p = 0,1633), quanto no número de condrócitos em GI (p = 0,9429) e GR (p = 0,1634). Conclui-se que duas semanas de imobilização e remobilização produziram apenas diminuição significativa no número de osteócitos nos ratos imobilizados; esse número continuou a diminuir mesmo nos animais remobilizados.Palavras-chave: alongamento muscular, estresse articular, metabolismo ósseo. ABSTRACTLong immobilization periods lead to bone and properties loss, and its recovery depends on many factors. Besides that, immobilization can cause ulcerations in the articular cartilage tissue due to alterations, such as loss of proteoglycans and total cartilage mass and volume. The aim of this study was to verify histological alterations of the periarticular bone tissue and articular cartilage caused by immobilization as well as remobilization of hinder limbs of Wistar rats. Twelve Wistar rats were divided in two groups: GI -(n=6): 15 days with the left hinder limb immobilized at plantiflexion, with the right limb being the control; GR -(n=6): used a 15 day-period of free remobilization in the cage, associated with 3 daily stretching bouts of the left soleus muscle for 30 seconds. The measures of the cortical bone thickness, diameter of the medular channel and number of condrocites were evaluated; in the cartilage tissue, the cartilage mean thickness and the number of condrocites were measured. The results showed that for GI ...
Because of multisystemic impairment in patients with Ellis-van Creveld syndrome, multidisciplinary care may be demanded since birth to assure breastfeeding. This report presents a case of an Ellis-van Creveld infant that was facing breastfeeding difficulties because of maxillary neonatal teeth. A 3 months old male infant with Ellis-van Creveld syndrome was referred to Pediatric Dentistry Department because of two upper neonatal teeth causing breastfeeding difficulties. Clinical examination revealed that teeth position was compatible to 51 and 61, and both presented uncommon ectopic soft tissue placement, conical crown and hypoplastic enamel covered by a large amount of dental biofilm. Radiography indicated they were of normal series and had 2/3 of crown completion. Due to teeth mobility that impaired breastfeeding, treatment option was exodontia. Early tooth eruption, such as in natal and neonatal teeth, by itself can’t be considered a reason for exodontia. But exodontia must be considered when an early erupted tooth(s) impairs breastfeeding, especially in systemically compromised infants. In this present case report, after teeth extraction, the infant was able to breastfeed and gain weight properly.
