Xerostomy, dental caries and periodontal disease in HIV+ patients.

We studied xerostomy and its correlation with periodontal and dental cavity diseases in HIV patients, through measurement of salivary flow and through variables such as saliva buffer capacity, salivary pH, periodontal index, MDF index, dental carie risk and risk of periodontal disease. One hundred patients were analyzed. They were distributed into two groups: Group I (test) - 50 patients evidently HIV+, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases, levels of T-CD4 lymphocytes, viral load and highly active antiretroviral therapy (HAART); and Group II - (control) 50 HIV- patients, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases. In both groups, measurement of salivary flow, pH and buffer capacity was made. Group I presented high MDF, bacteria plaque and bleeding, with a greater susceptibility to the risks of oral cavities and periodontal disease. The salivary flow and the buffering capacity of the saliva were low, indicating a high level of xerostomy. Two important modifying factors influence these pathologies in an incisive way: one is immunossuppression and the other is HAART therapy. The control exhibited results that are closer to normality; it had better oral-health conditions.

O uso da cintilografia para o diagnóstico de alterações das glândulas salivares em pacientes HIV+ou em AIDS / The use of scintigraphy for diagnosis of salivary gland diseases in HIV+ patients or in AIDS

A cintilografia não é um método utilizado como rotina em Odontologia, os autores na presente revisão de literatura mostram a importância desse método em procedimentos diagnósticos mais complexos e relacionam o método para diagnóstico de lesões em pacientes com HIV ou em AIDS. O uso da cintilografia é muito bem empregado para estudos das glândulas salivares, as quais, em pacientes HIV+ são encontradas com dimensões alteradas, que são visualizadas e mensuradas precocemente com o uso deste método de contraste. Além de proporcionar um um diagnóstico precoce dessas alterações e ser um exame de simples aplicação, a cintilografia vem se tornando mais freqüente, não só na área de diagnóstico bucal como em outras especialidades da Odontologia, e deve ser mais indicada
