A study of the willingness of 363 general dental practices in Brazil to accept a patient infected with human immunodeficiency virus for treatment of dental pain and the provision of routine dental care showed only 44% of dental practices to be willing to provide dental care. Willingness was influenced neither by financial factors nor the local prevalence of human immunodeficiency virus disease.

There is growing public recognition of the importance of oral health, as symbolized by the theme. "Oral Health for a Healthy Life" proposed for the 1994 World Health Day. In this report, the efficacy of antimicrobial mouth rinses, mainly Listerine, was reviewed by three investigators who are working as a microbiologist, a microbiologist, a dentist, and a dental hygienist participating in oral health care. Listerine, an antimicrobial mouth rinse, completely killed microorganisms in 10 to 30 seconds; the microbes includes methicillin-resistant Staphylococcus aureus, Streptococcus pyogenes, Helicobacter pylori, Candida albicans, Streptococcus mutans, Actinomyces viscosus, Porphyromonas gingivalis, Prevotella intermedia, and Actinobacillus actinomycetemcomitans. Listerine was also weakly effective in inactivating human immunodeficiency viruses. Bacteria in samples collected from human dental plaque and saliva were completely killed within 30 seconds when exposed to Listerine. When saliva samples were collected from subjects who had rinsed their mouths with 20 ml of Listerine or 1:50 diluted povidone-iodine, levels of viable anaerobic bacteria in the samples were reduced to 1%. When Listerine was used for oral surgery such as tooth extraction and periodontal surgery, the agent was effective in relieving toothache. This was probably due to a decrease in oral bacteria by the antimicrobial action of Listerine, leading to lowering the inflammatory response of the host. The use of antimicrobial mouth rinse during dental treatments such as endodontic treatment proved effective for more reliable infection control. In Japan, there are an increasing number of elderly and medically compromised hosts who are potentially at risk for developing pneumonia due to silent aspiration of microbes in the oral cavity and throat. For the aged with such potential risk, using of antimicrobial mouth rinse may be effective in preventing dental plaque accumulation when used in addition to the mechanical control of plaque, since they tend to have difficulty in brushing teeth by themselves. Indeed, the use of antimicrobial mouth rinse in these elderly people proved useful not only in preventing bacterial pneumonia, but also in improving their quality of life by preserving their oral health.

Plasmablastic lymphoma of the oral cavity is a form of non-Hodgkin lymphoma (NHL) and was first described in 1997. We describe a case of plasmablastic lymphoma in an HIV-infected patient who presented with an expanding oral lesion and symptoms of a toothache. We review all cases of plasmablastic lymphoma that have been reported in the literature. Plasmablastic lymphoma is strongly associated with immunodeficiency, and most particularly, with HIV infection. The pathophysiological origin of plasmablastic lymphoma has not been fully characterised, but the presence of Epstein-Barr virus (EBV) has often been documented in biopsy specimens, supporting a role for EBV in the pathogenesis of this lymphoma. The differential diagnosis for an expanding oral lesion includes both infectious and malignant processes. Biopsy is essential for making a correct and prompt diagnosis. Treatment usually involves chemotherapy, but antiretroviral therapy may also have an important role. Infectious disease clinicians should be aware of this newly described and increasingly encountered lymphoma, since it is prominently associated with immunosuppression and may be mistaken for other entities.

Burkitt's lymphoma is not an uncommon malignancy in the paediatric population. It is a high-grade non-Hodgkin B-cell lymphoma which may present as endemic, sporadic and human immunodeficiency-associated subtypes. The African, or endemic, variant usually involves the maxilla and other facial bones while head and neck manifestations in sporadic Burkitt's lymphoma are rare. We described a case of oral Burkitt's lymphoma involving the right jaw in a 4-year-old boy. The patient presented with a rapidly-enlarging swelling of one month duration, toothache-like pain and radiographical appearance of 'floating teeth' in the right mandible. Incisional biopsy revealed small round tumour cells with scarce cytoplasm and multiple small nuclei interspersed by phagocytic macrophages. The tumour cells were immunopositivity for CD20 and CD10, expressed weak positivity for CD3, negative for CD5 and showed > 90% positivity for Ki-67. Tumour remission was achieved with six cycles of chemotherapy with the CHOP regime.

Spilanthes acmella is an important medicinal plant, found in tropical and subtropical countries mainly India and South America. Popularly, it is known as toothache plant which reduces the pain associated with toothaches and can induce saliva secretion. Various extracts and active metabolites from various parts of this plant possess useful pharmacological activities. Literature survey proposed that it has multiple pharmacological actions, which include antifungal, antipyretic, local anaesthetic, bioinsecticide, anticonvulsant, antioxidant, aphrodisiac, analgesic, pancreatic lipase inhibitor, antimicrobial, antinociception, diuretic, vasorelaxant, anti-human immunodeficiency virus, toothache relieve and anti-inflammatory effects. This review is elaborately describing the traditional uses, phytochemistry, pharmacology, and toxicology of this plant. This review would assist researchers to search scientific information in the future.
