(1) The characteristics of third-molar development in children from 2 geographic areas of Croatia. [In Italian]. Minerva Stomatol 1997 Mar;46(3):103-8. Legović M, Mady L, Zupan M, Ceranić I, Bajan M. Cattedra di Pedodonzia e Ortodonzia, Facolta di Medicina, Universita degli Studi, Fiume, Croazia. PMID: 9173219, UI: 97253662. BACKGROUND: The development differences of wisdom teeth in children in two geographical regions of Croatia (Istria and Slavonia) have been studied. METHODS: One thousand orthopantomograms have been analyzed (Istria: 574-280 boys and 294 girls; Slavonia: 426-210 boys and 216 girls); they were carried out in children aged from 6 years and 6 months to 12 years and 6 months, divided into six groups. All of them presented the following criteria: absence of numerical anomalies of permanent teeth (wisdom teeth not included), absence of extraction of permanent teeth and of different syndromes. The development of wisdom teeth was assessed by Gat's method. RESULTS: The development of wisdom teeth begins earlier in Istrian subjects, but in both groups the wisdom tooth crypt appeared also after the 12 years and 6 months. The greatest increase is frequency of wisdom teeth germ in both groups was observed in children aged between 9 or 10 years. Most of Istrian children, compared with those in Slavonia, had wisdom teeth germs. As to jaw differences, it was observed that children in Istria (except the group of those 11 years old) have significantly more wisdom teeth germs in the mandible (p < 0.01). Significant jaw differences were found only in the group of 8-years-old Slavonian children. The differences in presence of wisdom teeth between males and females and sites of each jaw were not found to be significant. [Reprinted from Medline, per above hyperlink.] |

(2) The development of third molars in the children of [Istria] Croatia. Coll Antropol 1998 Dec;22 Suppl:127-32. Legović M, Mady L, Slaj M, Lapter M, Stefanac-Papić J. Department of Orthodontics, School of Medicine, University of Rijeka, Croatia. PMID: 9951153, UI: 99136304. The aim of this study was to determine the prevalence of third molars in children in Istria aged 7 to 18. The study was performed on 2350 panoramic radiographs of children in Istria that have been analysed and then divided into 7 age groups. Each of these groups consisted of the same number of boys and girls. It has been found that the development of third molars starts earlier in the mandible, and that before the age of 12 there are more third molars in the mandible than in the maxilla (p < 0.01). Nine-year old girls have statistically significantly more third molars than the boys of that age, but twelve year old boys have more than the girls. The differences in the prevalence of third molars between the jaw sides was statistically significant only for mandibles of twelve year old girls. Hypodontia of third molars has been found in 4.5% of boys and 5.8% of girls aged 14 to 18. [Excerpt reprinted from Medline, per above hyperlink.] |

(3) The development of third molars in the children of [Istria] Croatia. [In Russian]. Stomatologiia (Mosk) 1999;78(3):9-11. Legović M, Mady L. PMID: 10368596, UI: 99296977. The objective of this research was to investigate the prevalence of third molars in children in Istria aged 7 to 18. There are 2350 panoramic radiographs of children in Istria that have been analysed and then divided into 7 age groups. In each of these groups there was the same number of boys and girls. It can be expected that over 50% of examinees have third morals at ages between 10-11. The development of third morals starts earlier in the mandible, and it is statistically significant that there are more third morals in the mandible before the age of 12 than in the maxilla (p < 0.01). Furthermore, it is statistically significant that nine year old girls have more third morals than boys, but twelve year old boys more than girls. The differences in the prevalence of third morals between the jaw sides were statistically significant only for mandibles of twelve year old girls. Hypodontia of third morals has been found in 4.5% of boys and 5.8% of girls aged 14 to 18. [Excerpt reprinted from Medline, per above hyperlink.] |
Occlusal anomalies in the deciduous and mixed bites. Stomatologiia (Mosk). 1998; 77(3):51-5 (ISSN: 0039-1735). Legović M; Mady LIn 311 examinees (177 boys and 134 girls) with primary dentition and 535 examinees (285 boys and 250 girls) with mixed dentition in Istria--Croatia, the frequency of orthodontic and occlusal anomalies in regard of space plane and premature extraction of c, m1 and m2 are investigated. The orthodontic anomalies are fortified in 46.95%, premature loss in 11.25% and occlusal anomalies in 40.83% of examinees with primary dentition, while in mixed dentition the 58.69% of examinees have orthodontic anomaly, the 17.20% premature loss and the 48.97% of examinees have occlusal anomaly. In both phases of dentition the most frequent are occlusal anomalies: combination of sagittal-vertical plane, and those in sagittal and vertical space plane respectively. |

Occlusal anomalies in the deciduous and mixed bites. Stomatologiia (Mosk) 1998;77(5):56-60. Legović M., Mady L. L. PMID: 9867668, UI: 99072122. In 311 examines (177 boys and 134 girls) with primary dentition and 535 examinees (285 boys and 250 girls) with mixed dentition in Istria--Croatia, the frequency of orthodontic and occlusive anomalies in regard of space plane and premature extraction of c, m1 and m2 are investigated. The orthodontic anomalies are defected in 46.95%, premature loss in 11.25% and occlusive anomalies in 40.85% of examinees with primary dentition, while in mixed dentition the 58.69% of examinees have orthodontic anomaly, the 17.20% premature loss and the 48.97% of examinees have occlusal anomaly. In both phases of dentition the most frequent are occlusive anomalies in the following planes: sagittal, vertical and sagittal-vertical. |
Anomalies in the number of permanent teeth in orthodontic patients in 2 localities in Croatia. Schweiz Monatsschr Zahnmed. 1990; 100(3):286-90 (ISSN: 1011-4203). Legović M; Ceranić I; Cehich A. Facoltą di medicina dell'Universitą di Fiume, cattedra di pedodonzia e ortodonzia.The authors investigated the frequency of anomalies among permanent teeth in two regions in Yugoslavia--Istria and Slavonia--in a group of 4449 orthodontic patients (1890 boys and 2559 girls, age 6-18 years; in Istria: 1060 boys and 1341 girls, in Slavonia: 830 boys and 1218 girls). The anomalies were diagnosed by clinical examination and by orthopantomogram analysis. The anomalies were significantly more frequent in children of Istria compared to the ones of Slavonia, i.e. hypodontia was found in 6.25% versus 2.34% and hyperdontia in 1.37% versus 0.63%. Hypodontia in the mandible prevailed among the children in Istria while that in the maxilla among the children in Slavonia. The differences in the sequence of the hypodontia frequency for each tooth in both sexes have been established separately for the two regions. |
