Accuracy of a chair-side test for predicting caries risk compared with established methods. A pilot study.

Purpose: The aim of this study was to determine the prognostic accuracy of a new chair-side test, determination of lactic-acid production on the tongue, for caries-risk assessment according to caries increment within two years.

Methods: 35 children (6-8 years old) participated in the study. The past caries experience (df-t1, DF-T1), caries at second deciduous molars (df-2.

In vitro evaluation of enamel remineralisation by a casein phosphopeptide-amorphous calcium phosphate paste.

Purpose: The aim of this preliminary in vitro study was to evaluate the effect of a casein phosphopeptide and amorphous calcium phosphate (CPP-ACP) paste on untreated enamel surfaces that had previously been exposed to an erosive challenge.

Materials And Methods: Over a period of 6 h, enamel samples from five fully erupted, caries-free molars were incubated with apple juice and later covered with CPP-ACP paste for 15 min. Enamel samples incubated with physiological sodium chloride solution or with apple juice alone served as controls.

Comparison of a new chairside test for caries risk assessment with established methods in children.

Purpose: The aim of this study was to compare the results of a new method, measurement of lactic-acid production on the tongue (LAP), with established methods of caries risk assessment in children.

Methods: One hundred nineteen children (6-10 years old) participated in the study. Data collection included number of carious lesions (D-T) and filled teeth (F-T), approximal plaque index (API), LAP, buffering capacity (BC), counts of mutans streptococci (MS) and lactobacilli (LB) in stimulated saliva.

Usefulness of combining clinical and radiological dental findings for a more accurate noninvasive age estimation.

The aim of this study was to establish correlations of clinical and radiological dental findings, alone or in combination, with chronological age in adults. Dental findings and orthopantomograms of 984 patients (aged 20-60 years; 524 females/460 males) were analyzed. DMF-T index and distance (alveolar bone level, ABL) between cemento-enamel junction and alveolar bone margin were recorded.

Local gingival blood flow at healthy and inflamed sites measured by laser Doppler flowmetry.

Background: This investigation aimed to: 1) develop a method to obtain reproducible laser Doppler flow readings (LDFRs) at the gingiva of the maxillary front teeth; 2) evaluate regional gingival blood flow (GBF) in healthy gingiva by laser Doppler flowmetry; 3) compare hand-held LDFR (H-LDFR) with splint LDFR (S-LDFR); and 4) monitor changes in GBF in experimental gingivitis (EG) and chronic gingivitis (CG).

Methods: The LDFR, gingival index (GI), and plaque index (PI) were measured at 13 gingival sites (teeth #6 to #11) in 10 healthy volunteers (five males and five females), 23 to 34 years of age, over a period of 12.5 +/- 3.

Dystrophic epidermolysis bullosa: oral findings and problems.

Dystrophic epidermolysis bullosa (DEB) is one of the three major types of epidermolysis bullosa (EB), an inherited cutaneous disease with blister formation following minor trauma. A subtype of DEB is recessive dystrophic epidermolysis bullosa, Hallopeau-Siemens type (RDEB-HS), where marked scarring leads to deformities of extremities. In RDEB-HS the mucous membranes may also be involved and form adhesions with ankyloglossia and microstomia.

Effect of periodontal therapy on sulcular sulphide level a longitudinal study.

Purpose: The identification of active disease sites is a leading goal in basic periodontal research. Of toxic bacterial metabolites detectable in gingival crevicular fluid, volatile sulphur compounds (VSC) have been implicated in periodontal tissue destruction. Several bacteria associated with active destructive disease are capable of producing VSC, this fact supporting the idea of sulcular VSC being a possible marker of disease activity.
