The use of milk as a saliva substitute.

Xerostomia, a clinical manifestation of salivary gland dysfunction, affects many people. These individuals frequently sip liquids to alleviate the discomforts associated with hyposalivation. Milk appears to have many of the chemical and physical properties of a good saliva substitute. Besides the obvious benefit of providing moisture and lubrication for the dehydrated mucosa, milk buffers oral acids, reduces enamel solubility, and contributes to enamel remineralization. These anticariogenic factors are generally attributed to the high calcium and phosphate content along with the milk phosphoproteins that strongly adsorb to enamel. Patients with xerostomia frequently have difficulty in obtaining proper nutrition due to problems associated with lubricating, masticating, tasting, and swallowing food. Milk is a food with high nutritional quality that would certainly benefit most patients with xerostomia. Because of the nutritional, anticariogenic, and moisturizing properties of milk, patients with xerostomia may find milk of value as a saliva substitute to help reduce the oral health problems associated with hyposalivation.

The effect of cheese on dental caries: a review of the literature.

The relationship between nutrition and dental health has been a topic of interest for many years. Recently, the cariostatic properties of cheese have been the subject of intensive research. Most of these studies suggest that the use of cheese as the final food in a meal will help to reduce caries. Several mechanisms by which cheese may reduce enamel demineralization have been proposed. Chewing cheese stimulates saliva flow. The alkaline nature of saliva buffers the acids formed in plaque. There is also an increased rate of sugar clearance due to the diluting action of cheese-stimulated saliva. Research has also suggested that chewing cheese may reduce the levels of cariogenic bacteria. This may be secondary to the reduced incidence of caries as conditions within a carious lesion tend to promote the growth of these organisms. The high calcium and phosphorus content seems to be another factor in the cariostatic mechanism of cheese. Both casein and whey protein seem to be involved in the reduction of enamel demineralization. Casein phosphopeptides may also be responsible for some anticariogenicity by concentrating calcium and phosphate in plaque. An overview of the effect of milk on dental caries is also presented in this review.

Cyanoacrylates in dentistry: a review of the literature.

A discussion of the uses of cyanoacrylates in dentistry and an update of the literature have been presented. The biocompatibility and histotoxicity of this material has been considered. Studies have shown that the higher homologues are more tissue compatible than the lower. Local tissue responses show histiocytic proliferation and formation of giant cells. The foreign body cell responses are more pronounced when cyanoacrylate is placed deep in an extraction socket and under tissue flaps when compared with superficial application of the adhesive. While cyanoacrylate-induced neoplasia has been a concern, long-term studies are needed to provide more light on this and other histotoxicity problems. Cyanoacrylates are bacteriostatic for many bacterial types. It is apparent that cyanoacrylates could have some useful clinical applications in periodontics and oral surgery. They are very effective tissue adhesives and their use as a nonsuturing material would provide many advantages. Research indicates that use should be restricted to superficial application. The hemostatic properties of this material have been confirmed in virtually every study, but it should be used judiciously for this purpose. Several other potential periodontal and oral surgery applications were considered. It is expected that future research will examine new applications of the material for surgical use. Preventive and restorative applications were also discussed, but unfortunately, these have not met with much success. Newer techniques and materials seem superior in this aspect of dentistry. Possible application may eventually be shown in the desensitizing of dentin and cementum. Endodontic applications were also considered. While most studies indicate that cyanoacrylate would make an acceptable pulp-capping material, calcium hydroxide is still the material of choice.(ABSTRACT TRUNCATED AT 250 WORDS)

An agoraphobic patient with dental anxiety: report of case.

A 46-year-old woman made an appointment for dental therapy. The patient's agoraphobia and dental anxiety presented a difficult treatment situation. An open dialogue between patient and dentist along with a flexible treatment plan and unhurried appointments contributed to the success of the dental rehabilitation.

Psychophysical pain control during tooth extraction.

A case of a patient with multiple allergies to local anesthesia and who required extraction of a maxillary canine is reported. The patient used her psychophysical capabilities to control the pain and anxiety associated with the surgery. A discussion of psychophysical pain control is presented.
