In this review article, oral lesions in relation to HIV infection are presented and discussed. Lesions such as oral candidiasis, hairy leukoplakia and necrotising gingivitis or periodontitis may be the first sign of an HIV infection or of its progression. Almost all HIV-infected patients will contract oral diseases. Dentists and physicians play an essential role in early recognition of signs and symptoms of HIV disease or of its progression. Only through such recognition can appropriate definitive diagnostic testing be conducted and appropriate therapeutic intervention for the condition be considered. It is pivotal that both dentists and physicians are familiar with the most frequently occurring oral symptoms of HIV infection.

Varicella zoster virus (VZV) causes varicella (or chickenpox) and establishes latency in nerve ganglia after the primary infection. The reactivation of virus later in life can cause mono- or polyneuropathy. The cranial nerves most commonly involved are five (herpes zoster or shingles), six, seven eight, nine and ten. In the present study we describe the oral lesions associated with VZV infections in normal children. In a 3 year period we examined 62 children, age 2 to 13 years old with diagnosed varicella and a 4 year old boy with herpes zoster at the 3rd branch of the trigeminal nerve. According to the clinical picture of varicella, the disease was defined as: (1) group A mild cases; (2) group B moderate cases; (3) group C severe. The manifestations of varicella were: mild varicella 19 children, moderate 26 children and severe 17 children. The results of the present study indicate that the prevalence of oral manifestations of varicella is related to the severity of the disease. In 17 severe cases, oral lesions were always present and the number was between 5 to 30. From 26 moderate cases, oral lesions were observed in 23 and the number was between 2 to 10. From 19 mild cases, oral lesions were present only in 6 cases and their number was 1 or 2. Often varicella's oral lesions resemble manifestations of other entities, and this may cause differential diagnostics problems.
