Dentes gretados: o que clínicos e especialistas precisam saber / Cracked teeth: What clinicians and specialists need to know

A proposta da presente revisão de literatura foi estabelecer as evidências existentes sobre etiologia, sinais e sintomas, métodos de diagnóstico e tratamento de dentes gretados. Segundo a American Association of Endodontists (AAE), o termo dente gretado (DG) foi definido como uma fratura em um plano que quebra a continuidade do esmalte e da dentina, sem separação das partes, geralmente no sentido mesiodistal, passando pela superfície oclusal, podendo envolver uma ou ambas as cristas marginais. Essa fratura, por apresentar profundidade e direção desconhecidas, pode se estender até a polpa e/ou ligamento periodontal, levando a um quadro de pulpite reversível, pulpite irreversível, necrose pulpar ou, até mesmo, evoluir para uma fratura completa. Atualmente, os DGs estão relacionados à terceira maior causa de dentes perdidos, após cárie e doença periodontal. Estudos indicam uma falta de consenso entre profissionais sobre como tratar dentes gretados, uma questão clínica relevante, que precisa ser priorizada e esclarecida. Nesse contexto, essa revisão abordou a etiologia, sinais e sintomas, métodos de diagnósti- co e tratamento de dentes gretados (AU)

The purpose of this literature review is to examine the existing evidence regarding etiology, signs, symptoms, methods of diagnosis, and treatment of cracked teeth. According to the American Association of Endodontists (AAE), the term cracked tooth (CT) is defined as "a fracture in a plane that breaks the continuity of the enamel and dentin, without separation of the parts, usually in the mesiodistal direction, passing through the surface occlusal, which may involve one or both of the marginal ridges." Due to its unknown depth and direction, this fracture can extend to the pulp and periodontal ligament, leading to reversible pulpitis, irreversible pulpitis, pulp necrosis, or even progress to a complete fracture. Currently, cracked teeth are related to the third largest cause of missing teeth, after caries and periodontal disease. Studies indicate a lack of consensus among professionals about treating cracked teeth, a clinically relevant issue that needs to be prioritized and clarified. In this context, this review addressed the etiology, signs and symptoms, diagnostic methods, and treatment of cracked teeth (AU).

The clinical effect of endodontical therapy in the treatment of cracked teeth with different crack depth / 实用口腔医学杂志

Objective:To observe the clinical effect of endodontic therapy and full crown restoration in the treatment of cracked teeth. Methods:The trace and depth of 50 cracked teeth were carefully examined under root canal microscope.According to the depth and scope of the cracks,the cracked teeth were classficated into the degree of Ⅰ,Ⅱ and Ⅲ,treated endodontically and restored with full crown.Results:During 1 year follow-up,34 cases showed successful effect,5 progressive,1 1 failure.The general effectiveness rate was 78.0%.The effectiveness rate of group Ⅰ,Ⅱ and Ⅲ was 93.3%,82.1 % and 28.6% respectively.Group Ⅰand Ⅱ vs Ⅲ,P 0.05.Conclusion:The treatment effect of cracked teeth is closely related to the depth and scope of cracks.

The effect of pulp conservative restoration for early cracked teeth / 实用口腔医学杂志

38 molars diagnosed as early cracked teeth and without pulpitis were selected to carry out the clinical observation. All the teeth were prepared and restored by metal crown under local anesthesia. After 1-15 years follow-up, the efficiency was 84.20% and all the tested teeth showed no symptoms of pulpitis and kept good chewing function. The results suggests that for the teeth diagnosed as early cracked molars and without pulp inflammation, making metal crown with less dentin loss is a safe and scientific treatment method.
