선천치와 신생치는 출생시 맹출했거나 조기에 맹출하는 치아로 다양한 합병증을 가지고 있으나, 많은 부모들이 이에 대한 정보부족으로 적절한 치료 없이 불편을 겪고 있다. 본 연구는 2006 - 2015년에 경희대학교 치과병원 소아치과를 내원한 환아에게서 발견되는 선천치와 신생치의 특성을 평가하고자 한다. 환아들의 성별, 부모의 주소, 임상적인 특징과 합병증 및 치료법을 조사하여 후향적 연구를 진행하였다. 환아들 가운데 69%는 선천치를, 31%는 신생치를 가졌으며 모두 하악 절치였다. 여환이 남환보다 많았고 내원 주소로는 부모의 걱정이 가장 많았으며 병원 의뢰와 리가 페데병(Riga-Fede disease) 그리고 수유시 통증이 그 뒤를 이었다. 치료방법으로는 발치가 가장 많았으며 치아 유지와 치아 다듬기도 행해졌다. 선천치와 신생치는 다양한 특성과 합병증을 가지고 있으므로 치과의사는 아이의 전반적인 건강을 위해 이러한 치아의 병리에 대해 정확히 이해하는 것이 중요하다.

An objective definition of the anomaly is not avaliable and most investigators define the term differently or fail to describe their criterion. Because dental anomaly may lead to many complications, early detection and diagnosis of dental anomalies are essential steps in the evaluation of the child patient and in treatment planning. These procedures require detailed medical and dental histories, through clinical examination and the use of radiographs. So, this study was designed to find out the prevalence of dental anomalies. The clinical and roentgenographic examination was undertaken for 8,054 children at age from 0 to 15 years and statistical analysis was done. The results were as follows : 1. Among the examined subjects, 2,134 subjects(26.5%) showed dental anomalies. The prevalence of individual dental anomalies were as follows : supernumerary teeth 15.6%, congenitally missing teeth 6.6%, fusion 2.2%, odontoma 0.35%, microdontia 1.2%, macrodontia 0.05%, gemination 0.22%, talon cusp 0.36%, dens evaginatus 0.24%, dens invaginatus 0.15%, dilaceration 0.27%, taurodontism 0.09%, abnormal tooth position 1.7%, natal & neonatal teeth 0.92%, amelogenesis imperfecta 0.01%. 2. Significant correlations between the groups with individual dental anomalies were as follows : between group I and other groups, there was negative correlation, especially group I and group II. And the correlation coefficient between male and female showed differences. 3. For the supernumerary teeth group, the prevalence of male was higher than female(p<0.001). While for the congenitally missing teeth, macrodontia, microdontia, abnormal tooth position group, the prevalence of female was greater than male(p<0.001). 4. For the congenitally missing teeth group, the mandibular primary lateral incisor showed the highest incidence in primary dentiton, while mandibular lateral incisor in permanent dentition. In the mandible(72.5%), this site showed higher prevalence than in maxilla. In the case with deciduous congenitally missing teeth, the prevalence of successive permanent congenitally missing teeth was about 33.9%, the incidence was highest in mandibular lateral incisors. 5. Most supernumerary teeth existed on middle area and showed inverted position and unerupted state. In addition, supernumerary teeth showed higher incidence on maxilla (99.3%). 6. In the case with deciduous fused teeth, the prevalence of successive permanent congenitally missing teeth was 39.9%, while that of successive permanent fused teeth was 2.7%. And the highest rate of the prevalence (40.3%) appeared in fusion of mandibular deciduous lateral incisor and canine. 7. In the case of odontoma, the prevalence was higher in maxilla(78.6%) and anterior region(82.7%) than mandible and posterior region.

Pyknodysostosis is a rare autosomal recessive disorder characterized by the post natal onset of short limbs, short stature, and generalized hyperostosis along with acro-osteolysis with sclerosis of the terminal phalanges, a feature that is considered essentially pathognomonic. Other features include persistence of fontanelles, delayed closure of sutures, wormian bones, absence of frontal sinuses, and obtuse mandibular gonial angle with relative mandibular prognathism. We report a case of 17-year-old girl who presented with a chief complaint of retention of deciduous teeth. General physical examination demonstrated short stature, frontal and parietal bossing, depressed nasal bridge, beaked nose, hypoplastic midface, wrinkled skin over the finger tips, and nail abnormalities. Radiographs showed multiple impacted permanent and supernumerary teeth, hypoplastic paranasal sinuses with acro-osteolysis of terminal phalanges, and open fontanelles, and sutures along with wormian bones in the lambdoidal region.

Purpose: This study aimed to determine the frequency of abnormalities in the newborn oral cavity and to evaluate the association with prenatal and perinatal factors. Methods: This cross-sectional study evaluated 2,216 newborns. Oral findings were assessed in the first 24 hours of life using visual examination. Sex, weight, length, gestational age, and medical disorders at birth were recorded. Maternal demographic and medical information was also obtained. Results: The most common oral findings were Bohn's nodules, Epstein's pearls, and dental lamina cysts. Other intraoral findings included odontogenic cysts, ankyloglossia, and natal teeth, among others. In logistic regression analyses, folic acid consumption during pregnancy was significantly associated with Bohn's nodules (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.23-2.55; P=0.002), Epstein's pearls (OR, 1.63; 95% CI, 1.14-2.33; P=0.007), and dental lamina cysts (OR, 1.45; 95% CI, 1.02-2.05; P=0.038). Moreover, preterm births were negatively associated with prevalence of Bohn's nodules (OR, 0.63; 95% CI, 0.50-0.80; $P{\leq}0.0001$). Comparison between newborns with and without oral inclusion cysts showed that maternal folic acid and iron intake were significantly different (P<0.05). Conclusion: Maternal folic acid and iron intake were associated with the prevalence of oral inclusion cysts.
