Older persons are at risk of chronic diseases of the mouth, including dental infections (e.g., caries, periodontitis), tooth loss, benign mucosal lesions, and oral cancer. Other common oral conditions in this population are xerostomia (dry mouth) and oral candidiasis, which may lead to acute pseudomembranous candidiasis (thrush), erythematous lesions (denture stomatitis), or angular cheilitis. Xerostomia caused by underlying disease or medication use may be treated with over-the-counter saliva substitutes. Primary care physicians can help older patients maintain good oral health by assessing risk, recognizing normal versus abnormal changes of aging, performing a focused oral examination, and referring patients to a dentist, if needed. Patients with chronic, disabling medical conditions (e.g., arthritis, neurologic impairment) may benefit from oral health aids, such as electric toothbrushes, manual toothbrushes with wide-handle grips, and floss-holding devices.

Diabetes Mellitus (DM) is a multisystemic disorder with serious complications and these patients may also have serious problems with their oral cavity probably because of the microangiopathic and neuropathic complications. In diabetic patients, there may be several problems of the oral cavity such as gingivitis, periodontitis, candidiasis, glossitis, oral ulcerations, loss of taste sensations, opportunistic infections and several other conditions dependent on these. One of the recent theories about complications in DM is the contribution of reactive oxygen radicals. Paraoxonase (PON1) is an enzyme that is synthesized in liver and having the capability of hydrolasing the active metabolite of an insectisid, parathion. Previously it was shown that there are two polymorphic areas on the PON1 gene: one causing a Leu --> Met substitution at 55th position, the other causing Gln --> Arg at the 192nd position. We investigated the differences in PON activities related to the oral lesions in Type 2 diabetics and control subjects to see their relationships with PON1 activity levels and the two main gene polymorphisms of PON1 genes, PON1 192 and PON1 55. We had 51 patients and 53 healthy subjects used in the study. PON activity was significantly decreased in Type 2 DM group compared to the control group. Neither PON1 192 nor PON1 55 genotypes had any differential effect on PON1 enzyme activity levels in either group. However, we found that PON1 55 M allele carriers had greater risk for general periodontal and/or gingival problems.

Mucocutaneous findings in 150 HIV+ve cases (F, 79; M, 71) were evaluated over a one-year period. Mucocutaneous manifestations were seen in 96% with 2.9 mean number of dermatoses and mean cluster of differentiation (CD4) count of 196.33 cells/mm(3). The highest number of mean dermatoses, 3.29, was seen in individuals with severe immunosuppression. The most common mucocutaneous manifestation seen was candidiasis (35.33%), followed by seborrhoeic dermatitis (31.33%), oral pigmentation (29.33%), xerosis/ichthyosis (22.67%), pyodermas (22%), periodontitis (17.33%) and nail pigmentation (16.67%). Patient stratification according to the WHO immunological staging, according to CD4 counts, showed a statistically significant association (P < 0.05) for candidiasis, scabies, paronychia, oral pigmentation and diffuse hair loss. Nail and oral pigmentary changes, trichomegaly and subcutaneous fungal infections caused by dermatophytes were highlights of the study. Incidences of xerosis/ichthyosis, pyodermas, scabies and molluscum contagiosum reported in our study were higher and pruritic popular eruptions was lower than those in previous Indian studies. Cutaneous neoplasms were not seen in the present study.

A large number of studies showed that hairy leukoplakia, pseudomembranous candidiasis, Kaposi' sarcoma, non-Hodgkin's lymphoma, linear gingival erythema, necrotizing ulcerative periodontitis and necrotizing ulcerative gingivitis were the most common lesions in patients with HIV infection and AIDS, and their higher prevalence and incidence rates correlated with the falling CD4 counts and higher virus load of the patients. The use of highly active antiretroviral therapy (HAART) was associated with decreases in the prevalence of oral diseases. Oral manifestations may represent early signs of AIDS disease and call attention to disease progression. Oral fluid has been shown to possess superior sensitivity for HIV antibody detection as serum.

The purpose of this study was to determine the prevalence of oral manifestations in pediatric patients with acute lymphoblastic leukemia (ALL) receiving chemotherapy, and to evaluate the significance of independent risk factors (oral health, gender, age, time and type of treatment, and phase of chemotherapy). A cross-sectional study was made in 49 children with ALL between 2 and 14 years of age. To describe oral manifestations, a clinical diagnosis was made and the following criteria were applied: the OHI-S index to describe oral health and the IMPA index to describe periodontal conditions and to differentiate gingivitis from periodontitis. The prevalence of oral manifestations was: gingivitis, 91.84%; caries, 81.63%; mucositis, 38.77%; periodontitis, 16.32%; cheilitis, 18.36%; recurrent herpes, 12.24%; and primary herpetic gingivostomatitis, 2.04%. Other oral manifestations were: dry lips, mucosal pallor, mucosal petechiae, ecchymoses, and induced ulcers. The prevalence of oral candidiasis was 6.12%. It was observed that high risk ALL and poor oral hygiene were important risk factors for the development of candidiasis and gingivitis. The type of leukemia, gender and phase of chemotherapy were apparently associated with the presence of candidiasis, gingivitis, and periodontitis, and they could be considered risk factors for the development of oral manifestations.

Licorice, the name given to the roots and stolons of Glycyrrhiza species, has been used since ancient times as a traditional herbal remedy. Licorice contains several classes of secondary metabolites with which numerous human health benefits have been associated. Recent research suggests that licorice and its bioactive ingredients such as glycyrrhizin, glabridin, licochalcone A, licoricidin, and licorisoflavan A possess potential beneficial effects in oral diseases. This paper reviews the effects of licorice and licorice constituents on both the oral microbial pathogens and the host immune response involved in common ora-dental diseases (dental caries, periodontitis, candidiasis, and recurrent aphthous ulcers). It also summarizes results of clinical trials that investigated the potential beneficial effects of licorice and its constituents for preventing/treating oro-dental diseases.

AIDS-related lesions have decreased significantly since the advent of highly active anti-retroviral therapy (HAART). We describe an untreated, homeless 44-year-old male with a six-year history of HIV who presented himself with Kaposi sarcoma, candidiasis, scrofula and a generalized severe periodontitis. This report highlights the importance of identifying and diagnosing AIDS-related oral lesions seen in an untreated HIV-positive patient.

Xerostomia and salivary gland hypofunction are conditions that have been associated with increased prevalence of caries, periodontitis, and candidiasis. Oral health care providers must be aware of the etiologies and clinical manifestations of salivary gland hypofunction in order to identify patients with this condition and to prevent its potential complications. The various modalities available to manage this condition range from frequent sips of water to the intake of systemic medications like pilocarpine or cevimeline.

Inhalation therapy has been employed as the mainstay of the treatment in chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Beta-2 agonists, anticholinergic bronchodilators, inhaled corticosteroids, and sodium cromoglycate are often used alone or in combination in an inhaled form. Studies have shown that inhaled drugs used in the treatment have some adverse effects on the oral health based on their dosage, frequency, and duration of use. Several oral conditions such as xerostomia, dental caries, candidiasis, ulceration, gingivitis, periodontitis, and taste changes have been associated with inhalation therapy. Since the prevalence of chronic respiratory diseases is rising, it is important to provide optimal oral care to the individuals receiving inhalation therapy. This article will review the influence of inhaled drugs on the oral health of individuals and adequate management and prevention of the same.

Despite the protective role of diets rich in fruit plant polyphenols against some cancers and chronic degenerative and inflammatory diseases, insufficient emphasis has been placed on oral health. Numerous studies have aimed to ascertain the role of polyphenols in the prevention and treatment of oral diseases; however, even when in vitro evidence appears convincing, the same is not true for in vivo studies, and thus there is a general paucity of solid evidence based on animal and clinical trials. To the best of our knowledge, only two reviews of polyphenols and oral health have been published; however, neither considered the potential role of whole plant extracts, which contain mixtures of many polyphenols that are often not completely identified. In the present study, our main aim was to review the current state of knowledge (search period: January 1965 to March 2011) on the effects of plant extracts/polyphenols on oral health. We found data on grapes, berries, tea, cocoa, coffee, myrtle, chamomile, honey/propolis, aloe extracts and the three main groups of polyphenols (stilbenes, flavonoids and proanthocyanidins). Their effects on caries, gingivitis, periodontal disease, candidiasis, oral aphtae, oral mucositis, oral lichen planus, leukoplakia and oral cancer were investigated. The data suggest that there is a lack of strong evidence, in particular regarding randomized clinical trials. However, a fascinating starting point has been provided by pre-clinical studies that have shown interesting activities of polyphenols against the most common oral diseases (caries, periodontitis and candidiasis), as well as in oral cancer prevention.
