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. Gemination means that two separate morphological units
were created by division of the tooth germ. The intention of this study was to state the
prevalence of double teeth (fusion and gemination) among the persons tested, as to gender,
distribution in the maxilla or mandible, and whether the anomaly occurred bilaterally
or unilaterally. The results of this investigation have shown that in a total of examined
3,517 plaster models, a prevalence of double teeth was 0.2%. 57.2% of them were
fusioned and 42.9% geminated
Influence of Diet on Dental Caries in Diabetics
Two groups of population consisting of 84 patients suffering from diabetes (60 type I,
24 type II) and 69 nondiabetics of the same age have been examined on: oral hygiene index
(OHI), frequency of daily tooth brushing, dietary habits and incidence of dental caries
by registration of the decayed, missed and filled dental surfaces (DMFS-index). OHI
in type I and type II diabetes was found to bee slightly worse than in nondiabetics, but
not significantly (p > 0.05). In the number of daily tooth brushing there is not significant
difference between diabetics and nondiabetics. All diabetics have considerably
lower daily intake of total as well as simple carbohydrates than nondiabetics. The diabetics
have a significantly higher daily intake of dietary fibers, calcium and phosphorus
as well as the number of meals with simple carbohydrates and also DMFS-index than
the nondiabetics. A significantly higher incidence (p < 0.01) of caries location was found
on the buccal and labial cervical areas among patients suffering from diabetes. Explanation
for this could be more frequent daily intake of lowmolecular carbohydrates with
an improper calcium phosphorus ratio
