Salivary analyses and caries increment over 4 years: an approach by cluster analysis.

MAIN PROBLEM: Caries as a multifactorial process is influenced by salivary defense. Cluster analyses should give additional information on the role of salivary variables in relation to caries increment. METHODS: Samples of unstimulated and stimulated whole saliva from 28 young adults (mean age 23.5+/-2.1 years) were analyzed for flow rate, pH and buffer variables, lysozyme, lactoferrin, peroxidase, thiocyanate, secretory immunoglobulin A, and total protein. The decayed, missing, and filled surfaces (DMFS) were recorded at baseline and after 4 years. Cluster analyses were executed on the basis of salivary data. RESULTS: The mean caries increment (DeltaDMFS) over 4 years was 6.7+/-4.0 (range 1-16). In two-cluster processing, three out of four volunteers with low caries increments were grouped into one cluster. Only a few variables proved to be important for cluster characteristics. CONCLUSIONS: The results suggest that over 4 years (1) the volunteers with very low caries increment (DeltaDMFS=1) are classified always together, (2) these volunteers do not form a separate cluster by themselves, (3) low caries increment was related to higher salivary flow rate and lower levels of lysozyme and lactoferrin for unstimulated saliva and (4) the partial pressure of CO(2) was of importance in stimulated saliva.

[The assessment of the caries risk in young adults].

Several factors for caries prediction have been proved in a one-year follow-up study on 73 patients. The white-spot lesions have proved to be a good criteria for caries prediction in this population. These lesions could be combined with the microbiological tests Dentocult SM and Oricult N or with the determination of the buffer capacity (Dentobuff), which did not much improve the prediction.

[The plaque wet weight in subjects with different caries involvement].

Determinations of the wet weight of 48 h human dental plaque have proved that there is a significantly higher plaque wet weight among patients characterized by a low caries experience compared to patients with a high caries experience. The plaque-forming rate of patients with a low caries experience rises with advancing years.

[The light-cured composite CuRAY-FIL. A clinical and experimental animal study].

This article presents a animal study on 36 teeth by dogs without definite race. By the histological observation we cannot assess a damage of the pulp by application of CuRAY-FIL with a basic material. The clinical and REM observations after 11 and 24 months by 76 patients pointed out: CuRAY-FIL has a good colour stability and adhesion, however the claims on a optimal filling material for the restoration in the visible area are not accomplished in all points.

[The quantitative determination of resistance factors in the saliva of patients with very high caries involvement].

The unstimulated and stimulated whole saliva of patients with a very high caries experience were used for the determination of the flow rate, total protein, and the antibacterial proteins lysozyme, S-IgA and lactoferrin as well as the peroxidase and thiocyanate being components of the salivary peroxidase system. The concentration, the specific concentration and the secretion rate were calculated.

[Direct capping of the artificial exposed pulp in teeth with deep caries].

We carried out clinical and histological investigations on teeth with superficial and deep caries in which we made an artificial exposure of the pulp to check the reactivity of the endodont. After one year we observed using clinical and x-ray methods successful treatment in 93.4% of the teeth. Histologically the number of successful treatment was 100.0% in teeth with superficial caries and 80.0% in teeth with deep caries.

[Therapy of Class V cavities].

Despite of the necessity of an increasing primary prevention the therapy of class V cavities will be of greater importance already in the next future. In this review of the literature the indications, advantages, disadvantages as well as the practical procedure for the therapy of cervical lesions with amalgam, metal inlays, composites, glass ionomer cements, porcelain restorations,a nd composite inlays are discussed.

[Pulp-periodontal connections in bifurcation and trifurcation of six-year molars].

Differing and contradicting information is given in the literature about the number of accessory canals in the bifurcation and trifurcation of molars. The objective of these investigation was to establish the number of such canals by means of serial sections. In 12.5% of the teeth investigated accessory canals were found.
