Selecting an appropriate therapy for osteonecrosis of the jaws management based on current literature is a rational decision that can help lead to a proper treatment plan.
Dental treatment of patients with leukemia should be planned on the basis of antineoplastic therapy which can be chemotherapy with or without radiotherapy and bone marrow transplantation. Many are the oral manifestations presented by these patients, arising from leukemia and/or treatment. In addition, performing dental procedures at different stages of treatment (before, during, or after) must follow certain protocols in relation to the haematological indices of patients, aimed at maintaining health and contributing to the effectiveness of the results of antineoplastic therapy. Through a literature review, the purpose of this study was to report the hematological abnormalities present in patients with leukemia, trying to correlate them with the feasibility of dental treatment at different stages of the disease. It is concluded in this paper that dental treatment in relation to haematological indices presented by patients with leukemia must follow certain protocols, mainly related to neutrophil and platelet counts, and the presence of the dentist in a multidisciplinary team is required for the health care of this patient.
The erosion caused in vitro by cola-type and guaraná-type beverages (the latter is a soft drink sold in Brazil), and a canned lemon juice on the enamel of human deciduous teeth was analyzed. Morphological analysis of affected enamel was done using stereomicroscopy and scanning electron microscopy (SEM). The harmful effect of all test products on deciduous enamel was clearly demonstrated. Stereomicroscopy showed loss of gloss and an alteration in normal color of enamel, with irregular loss of dental tissue in variable degrees. Such a loss became more serious as the time of incubation increased. Different degrees of solubilization of enamel prisms were demonstrated by SEM, affecting initially the sheaths and the heads of prisms and later their tails. Areas of erosion increased in proportion to the time of incubation. All the products showed a great erosive potential on human deciduous dental enamel.
Reactive hyperplastic lesions had a high incidence among oral pathologies. The understanding of their clinical features helps to achieve a clearer clinical and etiological diagnosis, and the knowledge of factors related to their development. This may contribute to adequate treatment and positive prognosis.
ObjectiveTo evaluate the applicability of the cell block technique as a complementary
method for presumptive diagnosis in the analysis of cyst-like aspirates from jaw
lesions prior to histopathological diagnosis.Material and MethodsThe sample was made up of 17 cyst-like jaw lesions. After puncture, the aspirates
were centrifuged, fixed in formalin, embedded in paraffin and processed. All
lesions were biopsied and submitted to histopathological examination.ResultsIn 9 cases, the cytopathological analysis using the cell block method showed a
predominant presence of erythrocytes, inflammatory cells and few epithelial cells.
In the other 8 cases, the cell block technique demonstrated the presence of
parakeratin, whose histopathological analysis confirmed the occurrence of
keratocystic odontogenic tumors (KOTs).ConclusionsAccording to the studied cases, the cell block method was proven to be a simple,
fast and low-cost technique to effectively differentiate KOTs from other lesions
with similar clinical and radiographic features. The cell block technique
comprises cellular preparations useful to determine a clinical diagnosis and help
to develop a therapeutic plan for those lesions.
Background:Osteoradionecrosis of the jaw (ORNJ) is the most severe and complex sequel of head and neck radiotherapy (RT) because of the bone involved, it may cause pain, paresthesia, foul odor, fistulae with suppuration, need for extra oral communication and pathological fracture. We treated twenty lesions of ORNJ using low-level laser therapy (LLLT) and antimicrobial photodynamic therapy (aPDT). The objective of this study was to stimulate the affected area to homeostasis and to promote the healing of the oral mucosa.Methods:We performed aPDT on the exposed bone, while LLLT was performed around the bone exposure (red spectrum) and on the affected jaw (infrared spectrum). Monitoring and clinical intervention occurred weekly or biweekly for 2 years.Results:100% of the sample presented clinical improvement, and 80% presented complete covering of the bone exposure by intact oral mucosa.Conclusion:LLLT and aPDT showed positive results as an adjuvant therapy to treat ORNJ.
