Human saliva contains a number of physical physicochemical, and chemical agents that protect oral tissues against noxious compounds, in particular those produced by various microorganisms. Among such protective factors, the flushing effect of saliva flow is the most important one, not only because it so effectively removes exogenous and endogenous microorganisms and their products into the gut but also because a steady supply of saliva guarantees continuous presence of both non-immune and immune factors in the mouth. A great number of studies with controversial results have been published regarding various individual agents and their possible association to oral health, particularly to dental caries. It appears that no single chemical agent is far more important than the others. For example, patients with selective IgA deficiency have normal levels of non-immune defense factors and often display a compensatory increase in the other immunoglobulin isotypes. The concerted action of all agents in whole saliva, both saliva- and serum-derived, provides a multifunctional protective network that is collapsed only if salivary flow rate is substantially reduced. In this mixture of defense factors, many show additive or even synergistic interactions against oral pathogens. Increased knowledge of the molecular functions of various agents has made it possible to prepare oral hygiene product that include host-derived antimicrobial agents instead of synthetic agents. Although the clinical efficacy of such products is still unsatisfactory and poorly described, new technologies, for example in the production of specific antibodies against oral pathogens, may considerably improve the antimicrobial power of these products.

Diets high in fermentable carbohydrates are known to be highly cariogenic, particularly when contained in very sticky food such as dates. This medium allows food to remain in contact with the teeth, thereby resisting the normal flushing action of the saliva. When comprising a large portion of the diet, food such as this can lead to high caries incidence and accelerated tooth loss. This appears to be the situation found in a skeletal series from the late Iron Age in the Sultanate of Oman (100 BC-AD 893). Dental remains from 37 individuals were used in this study. Antemortem tooth loss (AMTL), caries, and dental attrition data were compiled from the 32 adult and juvenile specimens. In this sample, the caries rate is 35.5% of individuals (39.4% corrected), and 18.4% of teeth (32.4% corrected), while AMTL occurs in 100% (ten of ten) of preserved mandibles. Caries onset in permanent molars begins soon after eruption, with tooth loss and remodeling of the alveolus frequently complete by the time of third molar occlusion.

Local therapy of the oral cavity is used to treat conditions such as gingivitis, oral candidosis, oral lesions, dental caries, xerostoma and oral carcinomas. Delivery systems used include mouthwashes, aerosol sprays, chewing gums, bioadhesive tablets, films, gels and pastes. There are three major problems associated with drug therapy within the oral cavity: rapid elimination of drugs due to the flushing action of saliva or the ingestion of food, the non-uniform distribution of drugs within saliva on release from a solid or semisolid delivery system and patient compliance in terms of taste. Prolonged contact time of a drug with body tissue can significantly improve the clinical performance of many agents used for treating oral disorders. These improvements range from better treatment of local pathologies to improved drug bioavailability and controlled release to enhanced patient compliance. There are abundant examples in the literature over the past 15 years of these improvements using bioadhesive polymers. This manuscript summarizes the innovations pertaining to formulation and treatments as described in recent patents.

Skin changes associated with alcohol and drug abuse can be the earliest clinical manifestation of these disorders. The signs associated with these conditions may be distinctive and easily recognizable. Alcohol abuse can present with jaundice, pruritus, hyperpigmentation, and urticaria. Commonly associated vascular changes include spider telangiectasias, angiomas, caput medusas, flushing, and palmar erythema. Disease states related to alcohol abuse include psoriasis, porphyria cutanea tarda, and nutritional deficiencies. Alcohol abuse may predispose to the development of carcinomas of the skin, oropharynx, liver, pancreas, and breast. Cutaneous signs of drug abuse include skin granulomas, ulcerations, and recurrent infections. Specifically, oral disease and tooth decay are examples of stigmata often associated with methamphetamine abuse, a popular and inexpensive drug now on the scene. By being cognizant of these cutaneous markers of alcohol and drug abuse, dermatologists are often in the unique position of being able to recognize these changes, prompting early diagnosis and intervention, hopefully resulting in a better clinical outcome for these troubled patients and their families.
