Amelogenesis imperfecta (AI) is a disorder of genetic origin, linked to the amelogenin gene, which presents developmental abnormalities in the quantity and quality of tooth enamel. The main clinical problems are the extensive loss of dental tissue, occlusal problems, impaired aesthetics, tooth sensitivity and gingival inflammation. This study described a clinical case and the approach in the treatment of a patient with AI, with gingival plastic surgery, porcelain crowns on the posterior teeth, porcelain veneers on the anterior teeth and application of botulinum toxin to correct the gingival smile. AI is an anomaly with complex development and early diagnosis is essential for the conduct and success of the case, to improve aesthetics and function, preserving the characteristic tooth wear.
Optical fluorescence detection aims to identify precursor lesions, little noticeable to the human eye, and oral cancer. Squamous cell carcinoma or spinocellular carcinoma is a malignant neoplasm that affects the mouth more. In this article, two clinical cases are analyzed, treated with the use of two types of equipment, namely: the photoevidenciation by optical fluorescence of light-emitting violet wavelength of 405nm, power of 100mW, which is luminous radiation, not Ionizing and in the adjuvant treatment, we used low-power laser therapy, power 100mW, with two wavelengths of 808nm infrared, for pain relief, and the red 660nm, for oral mucositis. In Photodynamic therapy, the Photosensitizing Chimiolux® (methylene blue) was used to control Candida albicans. From these cases, we discuss how a more assertive diagnostic hypothesis can save a life and save time, resources, and efforts for the correct diagnosis of the pathology compared to a biopsy and histopathology negative for neoplasia. We conclude that optical fluorescence has excellent social relevance due to its potential to help the professional not specialized in the establishment of early diagnosis of oral cancer. Early diagnosis improves the rates of death caused by this carcinoma, which would extend the post-diagnosis survival and decrease the financial and emotional costs for the patient and family.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
