[Efficacy of therapeutic and preventive measures with the help of bite wing radiographs].

The effectiveness of caries diagnosis as seen in bite-wing pictures in the lateral dental segments was evaluated with reference to therapeutic and preventive control. Bite-wing x-rays of 328 patients aged 15-18 were included in the evaluation. The approximal segments from the ist premolars to the 2nd molars were taken into consideration. Further treatment was found to be necessary in 110 patients on the basis of the diagnoses exposed filling edge/split edge (45%), caries in dentine not adjacent to pulp (30%), secondary caries (15%) and caries in dentine adjacent to pulp (10%). Following an initial diagnosis of enamel lesions, preventive measures were necessary in 180 patients. The results document the importance of radiological checks of the permanent teeth in the approximal segments in youths. Bite-wing x-rays are also an effective means of monitoring the effectiveness of preventive measures.

[Caries protective effect of a NaF containing toothpaste with and without calcium carbonate polishing agent].

A caries preventive effect depending on the free fluoride concentration was registrated on rats using dentifrices with NaF or MFP (alone or in combination) despite the presence of CaCO3 as abrasive material because the composition of these dentifrices was changed. The free fluoride concentration of dentifrices had induced the accumulation of fluoride into enamel. The ionized fluoride content of NaF-dentifrices was unchanged for 3 years. MFP was hydrolized and had continuously released fluoride ions. The caries preventive effect which was increased by HCO3- was reproducible in correspondence with the fluoride concentration after the storage for two years.

Animals

[Root caries--a rat model].

A increasing alveolar bone loss and typical root surface caries were reproduced after defined co-inoculation of germfree Wistar rats with S. mutans and A. viscosus. The gnotobiotic rats were re-conventionalized and performed a gingivectomy on the right upper jaw at the beginning of the 12 week experiment.
