RESUMEN
Objective@#To explore the treatment options for congenitally missing teeth in patients with ectodermal dysplasia and provide a clinical reference.@*Methods@#A patient with ectodermal dysplasia with a concave midface, anterior protrusion of the chin, and underdevelopment of the lower third of the face presented with congenital loss of multiple maxillary teeth, malocclusion of the remaining teeth, congenital loss of mandibular dentition, small dental arches, and upper and lower alveolar bone hypoplasia. The patient was treated by means of a removable partial maxillary prosthesis, implants in the anterior region of the lower mandible designed with the assistance of digital guides, and bar-clamped implant-overlay prostheses. A literature review of the protocol for the treatment of this condition was also conducted.@*Results@#In addition to good retention and stability after denture wear, an excellent occlusal relationship, improvement of the patient's facial appearance, including upper and lower lip fullness, more equal balancing of the lower and middle 1/3 of the face, and improved masticatory function were achieved. The results of the literature review showed that patients with ectodermal dysplasia who are congenitally edentulous usually have a complex intraoral situation that makes restoration difficult, and common restorative modalities for these patients include fixed bridges, removable partial dentures, complete dentures, overdentures, and implant prostheses, which need to be selected according to the actual intraoral situation of each patient. Currently, there is no consensus on the treatment of congenitally missing teeth in patients with ectodermal dysplasia, and some scholars have suggested that fixed restorations be recommended for patients with fewer missing teeth, while the option of removable or implant-covered denture restorations should be given to patients with more missing teeth, with removeable prostheses for underage patients that are replaced with permanent fixed prostheses when the jaws have stabilized.@*Conclusion@#In patients with ectodermal dysplasia with congenital tooth loss, all factors should be taken into account, and an individualized restorative plan should be developed.
RESUMEN
@#Oral cancer has a high degree of malignancy, easily recurs, readily metastasizes and poor progonsis. Autophagy is a catabolic process induced in cells under stressful conditions. In recent years, studies have found that the activation of autophagy in epithelial cells can inhibit carcinogenesis and activate pathways such as mTOR and MAPK to activate autophagy in oral cancer cells and inhibit their survival. Inducing autophagy can degrade eukaryotic initiation factor 4E protein and inhibit oral cancer metastasis. Inducing autophagy in oral cancer cells can inhibit their proliferation and promote their apoptosis. Adding autophagy inducers to the treatment can help improve its efficacy and patient survival compared with chemoradiotherapy alone. In addition, the induction of autophagy in oral cancer cells can improve the body's immune function and enhance the efficacy of oral cancer immunotherapy. This article summarizes the relationship between autophagy and oral cancer and the role of induced autophagy in the treatment of oral cancer with the combined application of chemoradiotherapy and immunotherapy. The goal is to provide new ideas for inducing autophagy during the treatment of oral cancer, improving the therapeutic effect of oral cancer and the survival rate of patients. At present, the mechanism of action of induced autophagy in the treatment of oral cancer is not clear. Future research should study its mechanism of action, improve its therapeutic effect on oral cancer and develop autophagy inducers to accurately regulate and induce autophagy during the treatment of oral cancer.
