Abstract. The dentinal pulp complex marks the answer to any injury the tooth could be exposed to. In reference to pathologies, it was found that dental caries is not related to de AIDS stage. It was also found that positive and negative women have prevalence of caries. A longitudinal study showed that caries increased with age and decreased with the saliva fluid. It was found with SEM that enamel lamellae could be an associated structure to caries, and caries used dentin showed an alteration when demineralized, and this loss of mineral substance affects intertubular and peritubular dentin. With HAART therapy there’s a low caries index in relation to those without therapy. Purpose: describe the ultrastructural alteration in HIV patient’s dentin. Material and Method: Biopsies of posterior permanent tooth of HIV patients with caries diagnosed and extraction indicated in patients attending the Centre for the Care of Patients with Infections and Contagions diseases “Dra Elsa La Corte. Male and female, adults, HIV positive and HAART therapy. Simple extractions were made. Biopsies were processed by rutinary techniques of SEM. Results: irregular and few dentinal tubules near the pulp, intetubular dentin in a moderated quantity and low peritubular, both calcify. In intertubular dentin, in fixed dentin zone, near caries cavity the dentin is alter with low elements, carious dentin and some cells into the tissue. Conclusion: it is suggested that dentin viewed with SEM presents very marched alterations in its structure that even though are not different from the ones that were found negative patients, suggest a faster destruction and in higher quantities of tissue needing more studies about it
