Suppression of Streptococcus mutans in the mouths of humans by a dental prophylaxis and topically-applied iodine.

A prophylaxis followed by three topical applications of an iodine-potassium iodide solution significantly reduced the levels of Streptococcus mutans in fissure and approximal plaques and in saliva. Reductions persisted 20--24 weeks after treatment in salivary and approximal samples. A prophylaxis alone exerted a small and temporary reduction of S. mutans in occlusal fissure plaque, but did not reduce the levels of this organism in approximal plaque or in saliva. A significant relationship existed between the levels of S. mutans in saliva and the proportions of this organism in plaque. The dorsum of the tongue does not appear to constitute a significant reservoir for S. mutans following disinfecting procedures.

[Influence of dental caries prophylaxis using fluor-vigantoletten 1000 on plasma fluoride levels in infants (author's transl)].

A group of 57 newborns was divided into two: group I (27 subjects) received solely 1,000 I.U. vitamin D3 per day for 6 months, whereas group II (30 subjects) were given a combination of 1,000 I.U. vitamin D3 and 0.25 mg fluoride. At the end of the time of observation there was a significant difference between the plasma concentrations in the two groups. The median value was 13.06 microgram/l (range: 8:18-39.4 microgram/l) in group I and 16.54 microgram/l (range: 9.9--41.2 microgram/l) in group II. Fluoride is obviously available to infants when administered in combination with Vitamin D3. In addition, it could be proven, that after 6 month administration of fluoride there are no signs of cumulation, overdosage or even intoxication.

Effect of monthly professional mechanical tooth cleaning on periodontal health in adults.

The beneficial effects of comprehensive dental prophylaxis programs are well recognized. In order to study the factors determining the effectiveness of these programs, 28 periodontal recall patients were subjected to monthly professional mechanical tooth cleanings. Experimental and control teeth were randomly selected according to a splitmouth cross-over method. The Plaque and Gingival indices were recorded 1 month prior to the study, at the start, and at 4, 8, and 12 months. One month prior to the study calculus and bacterial plaque were thoroughly removed from all teeth. During the study period only the experimental teeth were cleaned. Efforts were made not to influence the oral hygiene of the participants by any other means. Following the initial tooth cleaning and during the preexperimental period the Plaque and Gingival indices decreased to a low level on both the experimental and control teeth (mean P1I = 0.4, mean GI = 0.3). This high standard of oral hygiene and gingival health was maintained throughout the study period, and no differences could be observed between experimental and control teeth. This indicates that factors other than the mechanical professional cleaning were responsible for the maintenance of gingival health. It is suggested that participation in the program in itself may have motivated the patients to improve their oral home care.

[Patient motivation by application of an individual intensive program for obtaining oral health].

The failure of group and individual dental prophylaxis based upon an authoritarian relationship between doctors and patients is demonstrated. In a new information and motivation program, the Hygiene Intensive Program (HIP), the patient's attention is focused on gingival bleeding as an unmistakable warning symptom of oral disease. The degree of marginal inflammation is scored using the Papillary Bleeding Index (PBI). The HIP is designed to introduce trust and confidence into the cooperative efforts of the dentist and the patient. The patient can see the increasing success of the dentist's work and judge the effect of his personal oral hygiene efforts. The possibilities for the cooperation of the increasingly involved third party of the dental "Troika", the actual purchaser of dental services (health insurance, social welfare system, etc.) in the HIP are discussed.

Production and origin of oral malodor: a review of mechanisms and methods of analysis.

Organoleptic studies indicate that the oral cavity is usually the principal source of physiologic malodor associated with the early morning halitosis. In all individuals, regardless of the age or health status of the oral tissues, the most intense oral malodor is exhibited after prolonged periods of reduced saliva flow and abstinence from food and liquid. This results from normal metabolic activity in the oral cavity and is accentuated in cases with periodontal involvement. Physiologic oral malodor is transient in duration as it can be controlled to varying degrees in most individuals by oral hygiene measures, such as tooth brushing, dental prophylaxis, tongue scraping and rinsing with antiseptic mouth washes. Experimental evidence strongly suggests that putrefaction of sulphur-containing proteinaceous substrates by predominantly gram-negative oral microorganisms is the primary cause of oral malodor. Optimum putrefactive activity occurs in low carbohydrate environment, physiological pH, and anaerobic conditions. Salivary sediment containing the exfoliated epithelial cells is the primary source of substrate which exists in a disulphide state. Proteolysis and reduction of disulphide bonds precedes the formation of odor. The odor intensity of putrescent saliva and plaque head-space vapor has been correlated with the concentration of volatile sulphur compounds consisting of hydrogen sulphide, methyl mercaptan, dimethyl sulphide and dimethyl disulphide. Except for dimethyl disulphide, the same sulphur-containing compounds have been found in mouth air of all tested individuals. Hydrogen sulphide and methyl mercaptan emanate an offensive putrid odor and account for approxiamtely 90% of the total sulphur content of mouth air. In half of the population tested, methyl mercaptan and hydrogen sulphide content of early morning mouth air is sufficiently high to account for the oral malodor. Brushing studies indicate that both plaque and tongue are important sources of malodor with most of the odor emanating from the dorso-posterior surface of the tongue. None of the gas chromatographic or mass spectrometric analyses have detected the presence of amines, indole, or skatole in the head-space, mouth air, or breath vapor samples.

Radioisotope determination of apical seal integrity of silver point-filled endodontic teeth after ultrasonic vibration.

Twenty-six human mandibular incisors with single root canals were instrumented and obturated with silver points and sealer. The efficacy of the initial seal was tested by immersion in radioiodine and counted for gamma radiation. Subsequently, the teeth were subjected to the vibration of an ultrasonic scaling device and reimmersed in the isotope so that the integrity of the apical seal could be re-evaluated as a function of increased radioiodine uptake and, thus increased gamma radiation. No significant difference was found after use of the Cavitron device.
