Caries and oral hygiene in children in postwar Novi Travnik (Bosnia and Herzegovina) and Zabok (Croatia).

The study was performed in 1997 and involved school children between the age of 6 and 12 in Novi Travnik, Bosnia and Herzegovina (n = 203) and Zabok, Croatia (n = 132). OHI-S (Simplified Oral Hygiene Index by Green-Vermillion) and DMF (Decayed, Missing, Filled) index were used as main outcome measures. Prewar data were taken from the respective literature.

Double tooth.

The form of primary and permanent teeth can differ morphologically from that which is considered normal, completely or in some parts. The changes in tooth form can be hereditary or caused by some disease or trauma. Fusion is a union of one or more teeth during development.

Tooth morphology in function of selfprotective mechanism.

The degree of curvature of vestibular and oral tooth surfaces is determined by the shape sequence from the tooth crown to the epithelial attachment and the alveolar bone, and directly influences the health of gingiva and the entire tooth support system. The goal of this research was to determine vestibulo-oral planes of upper and lower permanent premolars and molars and the thickness of the associated alveolar osseous wall, and 2,727 measurings were processed using pertinent statistical procedures. The results have shown the degree of curvature of vestibular and oral tooth surfaces to be higher in upper teeth than in lower ones (p > 0.

The influence of dental amalgam on the blood count.

The purpose of this research was to determine the influence of dental amalgam on the blood count of the holder of amalgam fillings. The experiments were performed on 30 Wistar rats. One group of rats received 8 mg of fragmented dental amalgam daily incorporated in their food during 60 days (group S2) and group S3 received amalgam fillings in their anterior teeth, which remained for 60 days.
