Dentes ectópicos são frequentemente encontrados, entretanto, terceiros molares inferiores ectópicos são incomuns, com etiologia obscura e pouco descritos na literatura pertinente. Sua localização já foi relatada nas regiões condilar, subcondilar, incisura mandibular, ângulo e borda inferior da mandíbula. Devido à importância do planejamento terapêutico, manejo adequado e variedade das manifestações clínicas desta condição, este trabalho teve como objetivo relatar um caso clínico de terceiro molar inferior ectópico na região de incisura mandibular, com radiolucência aumentada ao redor da coroa, em um paciente do gênero masculino, de 28 anos e sem sintomatologia. Acompanhamento radiográfico pode ser indicado, no entanto, em pacientes sintomáticos ou com alterações patológicas associadas, a extração deve ser considerada. Diante disso, o tratamento de escolha foi a extração do dente 38 sob anestesia geral, por via intraoral, tendo em vista a posição dentária, radiolucência e morbidade associadaà cirurgia. O tecido mole circundante foi enviado para análise anatomopatológica. O paciente evoluiu sem intercorrências durante avaliação pós-operatória.

Dental trauma injuries occur more frequently in upper anterior teeth, especially in enamel and dentin without pulp involvement. This article presents a clinical case report of a patient dissatisfied with the color of the tooth 21 restoration performed after suffering dental trauma. The format was adequate, so a previous molding of the palatal region was performed, and a condensing silicone guide was made. The use of the palatal guide facilitates the execution of the restoration and guides the layering of selected resins. Following the Natural Stratification concept, this case demonstrated a restorative treatment of direct restorations in composite resin, which can be considered an alternative for fractured anterior teeth, presenting clinical agility and excellent esthetic results.

Enamel developmental defects (DDEs) can cause clinical and aesthetic discomfort to patients. The choice of treatment depends on the type and severity of the defect. The objective of this work was to present a micro-invasive treatment option for a type of DDE. This report addresses a 14-year-old patient with a complaint about the color of her teeth. Mainly in element 11, which had a white, smooth, and opaque spot in its middle third. Upon clinical and radiographic examination, Molar Incisor Hypomineralisation (MIH) was diagnosed. Because of her age, micro-invasive treatments such as tooth whitening and the application of resin infiltrant (ICON - DMG) were proposed. Initially, an in-office bleaching session (35% hydrogen peroxide) was performed followed by home bleaching (10% carbamide peroxide) for 3 weeks. The initial color was found using the Vita scale, was close to A2 and the result obtained after bleaching was close to B1. Two weeks after the bleaching process, the resin infiltrant was applied to mask the stain. The results obtained were highly satisfactory. Resin infiltration to mask DDE is a minimally invasive and immediate approach that can mask diffuse opacities improving esthetics.
