Novas perspectivas para reabilitação de dentes tratados endodonticamente / Novel perspectives for the rehabilitation of endodontically treated teeth

Vários fatores podem influenciar o desempenho clínico de dentes com tratamento endodôntico (DTE). Além disso diversas são as opções restauradoras indicadas em respeito a este cenário, em especial com o notório avanço de novas técnicas e tecnologias para uso clínico. Dentre estas corriqueiramente envolvem-se o uso de restaurações diretas (confeccionadas com resina composta), pinos metálicos ou de fibra de vidro, pinos pré-fabricados ou fresados, assim como restaurações indiretas compostas de coroas cerâmicas, inlays, onlays ou endocrowns; sempre com o foco na reabilitação funcional e estética do caso em tela. Neste trabalho, através de uma revisão narrativa, foram expostos conceitos relativos às modalidades restauradores que se advêm do uso de novas tecnologias na reabilitação de dentes tratados endodonticamente(AU)

Several factors may influence the clinical performance of endodontically treated teeth (ETT). In addition, there are several restorative options indicated regarding this scenario, especially with the notable advance of new techniques and technologies for clinical use. These routinely involve the use of direct restorations (made of composite resin), metal or fiberglass posts, prefabricated or milled posts, as also indirect restorations composed of ceramic crowns, inlays, onlays or endocrown; always focusing on functional and aesthetic rehabilitation of the case in hand. In this study, through a narrative review, concepts related to the restorative modalities that were introduced with the use of new technologies in the rehabilitation of endodontically treated teeth were discussed(AU)

Morphology of the palatal rugae before and after orthodontic treatment with and without rapid maxillary expansion and dental extractions.

BACKGROUND: The palatal rugae contribute to oral swallowing, taste perception, and speech. From a forensic point of view, the distinctive morphology of these structures can be used to support human identification. However, the morphology of the rugae may be altered by trauma or therapeutic interventions in the palate. OBJECTIVE: This study aimed to analyze the morphology of the palatal rugae before and after orthodontic treatment performed with and without maxillary expansion and dental extractions. MATERIALS AND METHODS: The sample consisted of 60 dental casts taken before (n = 30) and after (n = 30) orthodontic treatment from patients aged >18 years. The patients were treated with rapid maxillary expansion by using Haas appliance (n = 10), by extracting the maxillary first premolars (n = 10) and by using only conventional fixed orthodontic appliances (n = 10). All the dental casts were analyzed twice by two independent examiners that were blind for the type of treatment. RESULTS: All the differences between groups were statistically significant (P < 0.05). More alterations in the morphology of the palatal rugae were observed in patients treated with rapid maxillary expansion, whereas few alterations were performed in patients treated with no maxillary expansion or dental extractions. CONCLUSION: The use of palatal rugae for forensic purposes must be avoided in patients that underwent invasive orthodontic treatments, such as those founded on maxillary expansion and dental extractions.
