Mucosal Surfaces

The majority of bacteria which colonize humans display sharp host and tissue tropisms; consequently, relatively little is known about how they initiate colonization on mucosal surfaces. The mouth has a variety of features which have enabled it to serve as a useful model for the discovery of basic principles of host-parasite interactions occurring in mucosal environments. Early studies demonstrated that indigenous bacteria attach to surfaces of the mouth in a highly selective manner; attachment was often observed to correlate with colonization. These studies led to the recognition that bacterial attachment is an essential step for colonization in environments which contain surfaces exposed to a fluid flow. Bacterial adhesion has subsequently grown into a major area of infectious disease research. Many bacteria have been found to possess proteinaceous components, called "adhesins", on their surfaces which bind in a stereochemically specific manner to complementary molecules, or "receptors", on the tissue surface. Adhesins are often lectins which bind to saccharide receptors, but some adhesins are thought to bind to proteinaceous receptors. Studies of components of human saliva, which adsorb to hydroxyapatite (HA) surfaces similar to those of teeth, and promote the attachment of prominent plaque bacteria, have revealed that the acidic proline-rich proteins (PRPs) promote the attachment of several important bacteria. These include strains of Actinomyces viscosus, Bacteroides gingival is, some strains of Streptococcus mutans, and others. The salivary PRP's are a unique family of molecules. However, segments of PRPs are structurally related to collagen. This may be significant, since B. gingivalis and certain cariogenic streptococci bind to collagenous substrata, and such interactions may facilitate their invasion into gingival tissues, or into dentin or cementum, respectively. Another unexpected observation was that although A. viscosus and other bacteria bind avidly to PRPs adsorbed onto apatitic surfaces, they do not interact with PRPs in solution. PRP molecules evidently undergo a conformational change when they adsorb to HA, and adhesins of A. viscosus recognize cryptic segments which are only exposed in adsorbed molecules. This provides the bacteria with a mechanism for efficiently attaching to teeth while suspended in saliva. It also offers a molecular explanation for their sharp tropisms for human teeth. It has proven convenient to refer to such hidden receptors for bacterial adhesins as "cryptitopes" (from cryptic, meaning hidden, and topo, meaning place). The generation of cryptitopes due to conformational changes or because of enzymatic modifications appears to be involved in the colonization of several bacteria on mucosal surfaces. In addition, there is evidence which suggests that elevated levels of neuraminidases and proteases associated with poor oral hygiene and gingivitis may also generate cryptitopes which promote colonization of certain Gram-negative bacteria associated with destructive periodontal diseases. These enzymes concurrently destroy receptors required for attachment of relatively benign species such as S. mitis and S. sanguis. Thus, the elevated levels of enzymes previously reported present in crevicular fluid and saliva of individuals with poor oral hygiene appear to have the potential to modulate bacterial colonization.

Exciting Time

Pregnancy is a unique, exciting time in a woman's life, and there are so many changes going on in human body during pregnancy and mouth is no exception , so good oral hygiene is extremely important during pregnancy . Usually oral health is often the most neglected form of health during all stages of life & the most important cause for this neglection is lack of awareness among people & this problems also increases when a lady is pregnant because of mis-perceptions and mis-leading information in the society or due to lack of knowledge. But the fact is during pregnancy many complex physiologic changes occur in the women’s body, which can adversely affect oral health and in turn those oral health problems may lead to pregnancy outcomes like preterm birth or low birth weight. Proper oral care is of utmost importance during pregnancy to avoid these complications. Avoiding foods that may cause oral problems, proper brushing and flossing and having dental consultations on a regular basis are steps to ensure good oral health during pregnancy.

International Experts

Since the 1990s numerous international experts have reported about the somatic complications of eating disorders including those having a dental and stomatological nature. Several reports emphasised that deformations in the oral cavity resulting from this grave nutritional disease typical of the young generation could already appear in the early stage and, therefore, dentists are among the first to diagnose them. Dentists are still often unaware of the importance of their role in multidisciplinary treatment. Even if they knew what the disease was about and recognised it on the basis of deformations in the oral cavity in time, their advice that their patients should brush their teeth more often would fail to eliminate the root cause of the problem. Not only the earliest possible treatment of the complications of the bingeing-purging mechanism and the maintenance of oral hygiene are important, but controlling and curing pathological habits with active participation of psychiatrists are also required to ensure full recovery. Due to the multidisciplinary nature of the disease, manifold communication is required. For this reason, publishing the dental ramifications of organic and systemic diseases at dental conferences and in technical journals, as well as providing information about oral complications of eating disorders for general practitioners and specialists are particularly important.
