Taurodontism in Down's syndrome.

Forty-three pantograms of the subjects with Down's syndrome were examined for the diagnosis of taurodontic teeth, grade of taurodontism, sex distribution and individual tooth involvement. Taurodontic teeth were found in 55.8% of the subjects, 32.6% females and 23.2% males. Second molars were most frequently affected (53.2%), followed by first molars (40%) and third molars (6.5%). The mesotaurodontic form was the most frequent form of the anomalia (72.5%). Hyypotaurodontic teeth were observed in 9.7% and pyramidal teeth in 17.7% of the cases. Hypertaurodontic teeth were not found.

Hypodontia in patients with Down's syndrome.

The aim of this study was to assess the prevalence of hypodontia in subjects with Down's syndrome. A group of 112 subjects with cytogenetically confirmed diagnosis of Down's syndrome, aged 12-36 years were examined. Hypodontia of the permanent teeth has been established on the basis of dental examination and orthopantomogram analysis in all cases. Hypodontia was present in 38.6% patients. Upper lateral incisors were most commonly missing. In patients with Angle class I, hypodontia most frequently referred to upper left lateral incisors, upper left first premolars and lower left second premolars. In patients with Angle class II, lower second premolars and upper incisors were most commonly affected by hypodontia. In patients with Angle class III, hypodontic findings more frequently referred to the maxilla as compared to mandible.

Basic amino acid in the pathogenesis of caries.

Amino acid pattern in total saliva was studied in 43 children with caries, aged 12-15 years, using the method of ion exchange chromatography. The results were compared to those obtained in a control group of 39 children without caries. In saliva from the children with caries, a significantly lower level of arginine (22.02 mumol/l), and a complete lack of histidine and its derivatives were observed when compared to the control group, where the concentrations of arginine and 1-methylhistidine were 28.36 and 26.34 mumol/l, respectively. The results obtained suggested that a decreased concentration of arginine, and a lack of histidine and its derivatives might imply an increased risk of caries.

Oral health in SFR Yugoslavia in 1986.

A pilot oral health epidemiological survey using WHO assessment forms was conducted in Yugoslavia in the year 1986. The study population consisted of 2600 persons aged 6, 12, 15, 18, 35-44, and over 65 yr. The survey included 22 towns (11 developed and 11 underdeveloped) in the six Republics and two Provinces of Yugoslavia. The results showed the prevalence of dental caries in the Yugoslav population to be very high (98.7% in 12-yr-olds). The mean decayed, missing, and filled teeth (DMF) scores were as follows: 6.1 at age 12 yr, 9.6 at age 15, 10.9 at age 18, 18.0 at age 35-44, and 28.0 in persons aged over 65 yr. Assessment of the periodontal status showed calculus to be the predominant disorder in the age groups 18 and 35-44 yr, while loss of sextants prevailed in persons aged over 65 yr.
