AIM: This study investigates the influence of early childhood caries (ECC) on the occurence of developmental defects of enamel (DDE) on permanent teeth. METHODS: Study design: This prospective original study was conducted to monitor the relationship between ECC in primary dentition and DDE as their consequences on permanent successors. One hundred and forty children were recruited and included in the study group with diagnosed ECC (ECCG) (N=60) or the control group (CG) (N=80). Deciduous upper central incisors were assessed for existing dental caries according to the dmft index and the modified pufa score and permanent incisors were examined using the modified DDE index. RESULTS: Prevalence of DDE was 19.3% in the whole sample; in ECCG it was 24.2% and 12.6% in CG. The most common defect was diffuse opacity with a prevalence of 44.8% in ECCG and 72% in CG. Prevalence of hypoplasia was 13.8% in ECCG, in CG it was present as a combination defect with a prevalence of 4%. The extent of less than 1/3 of labial aspect was in 69% of defects in ECCG,in CG it was 52%. The location of defects in the incisal third was 48.3% in ECCG and 32% in controls. CONCLUSION: A statistically significant relationship between ECC and DDE was not observed. The results were compared with studies about the relationship between ECC and DDE.

Okolo 6. týdne nitroděložního vývoje se epitelová ztluštění přeměňují v srpkovitý pruh epitelu, laminu dentalis, která se vzápětí postupně rozděluje do řady deseti samostatných ostrůvků, zubních pupenů, základů budoucích dočasných zubů. Dočasný chrup se prořezává od 6. do 30. měsíce života a erupci doprovází prudký nárůst diferencované enzymatické aktivity.
Around the 6th week of intrauterine development, the epithelial thickening transforms into a crescent-shaped strip of epithelium, the dental lamina, which is then gradually divided into a number of ten separate islets, dental buds, the foundations of future deciduous teeth. Deciduous teeth are erupt from 6 to 30 months of age and the eruption is accompanied by a sharp increase in differentiated enzymatic activity. Deciduous tooth takes place through the mucosa during an eight-day window that includes four days before tooth eruption, the day of the eruption and three subsequent days. Systemic symptoms ascribed to deciduous teeth eruption include irritability, sleep disturbances, crying, rhinorrhea, diarrhea, loss of appetite, excessive salivation, increased need for biting and a slight increase in temperature (by 0.6 °C), especially on the day of the eruption, but not actual fever. Deciduous teeth rarely appear in the mouth at birth or may erupt during the first month of life. They are called natal and neonatal teeth and can be mistaken for small, white or off-white lesions on the newborn's alveolar mucosa, which are usually multiple but non-enlarging, Epstein's pearls, Bohn's nodules, and gingival cysts.

Úvod: Zubní kaz v dočasném chrupu popřípadě jeho komplikace ovlivňují orální i celkové zdraví dítěte. Kaz časného dětství je definován jako kariézní léze či výplň na kterékoli zubní plošce nebo zub extrahovaný pro kaz u dětí mladších než 71 měsíců. Ošetření je komplikováno omezenou spoluprací dítěte, morfologickými a biologickými rozdíly dočasných zubů oproti zubům stálým a značně odlišným charak-terem progrese kariézních defektů.Vlastní sdělení: Cílem ošetření dočasných zubů je opravit či limitovat poškození zubních tkání způsobené zubním kazem, ochránit zbylé zdravé zubní tkáně, obnovit žvýkací funkci chrupu, zlepšit estetický vzhled, předejít zánětlivým komplikacím a usnadnit péči o hygienu ústní dutiny. Ne-vhodné nebo žádné ošetření dočasných zubů dítě handicapuje a významně zvyšuje riziko zánětlivých komplikací v podobě postižení zubní dřeně a následného šíření infekce do okolních tkání, poruchy zdraví dítěte a psychosociální problémy. Zubní kaz v časném dětství představuje zátěž nejen pro dítě a kvalitu jeho života, ale také pro rodiče a společnost v podobě zbytečných ekonomických výdajů. Cílem sdělení je shrnout závažné dopady zanedbání péče o dočasný chrup. Závěr: Naším prvořadým zájmem na individuální i komunitní úrovni by měla být prevence, neboť hlavní i podpůrné etiologické faktory zubního kazu jsou dobře známé. Velmi vysoký a neklesající výskyt neošetřených zubních kazů u malých dětí v celosvětovém měřítku však vypovídá o tom, že současná primárně preventivní opatření jsou nedostatečná a jsou dokladem kolize rizikových kariogenních faktorů a nesprávného životního stylu souvisejícího s působením sociálních, vzdělanostních, behaviorálních a v neposlední řadě i ekonomických faktorů.
Introduction: Early childhood caries and its complications have the negative impact on both oral and general health of the affected child. Dental caries in early childhood is defined as the presence of any decayed, filled tooth surface or missed primary tooth due to caries of a child under 71 months of age. The treatment of dental caries in small children is complicated due to limited cooperation, morphological and biological differences of primary teeth and caries lesion progression. Presentation: The purpose of the treatment of dental caries in young children is to repair and limit further damage of dental hard tissue, protect the remaining healthy tissue, restore the masticatory function, improve the aesthetics, prevent the inflammatory complications and facilitate the daily oral hygiene practice. Inappropriate and failed treatment of primary teeth may disadvantage these children; increase the risk of inflammatory complications in terms of pulp diseases and subsequent spreading of inflammation into surrounded tissues, general diseases and social problems. This disease has an impact on the quality of life of children and their families and is unnecessary burden to society. The aim of this paper is to review the consequences of neglect and failed treatment of early childhood caries. Conclusion: Prevention of dental caries would be preferable on individual and community level, because the main aetiological factors of dental caries are well defined. But the high level of untreated caries world-wide suggests that the current preventive approaches are not sufficient and are proof of collision of risk factors and inappropriate lifestyle associating with social, educational, behavioural and economic inequalities

The present study aimed to evaluate the frequency and time of the development of enamel hypoplasia of the primary canine of the Slavic population from the 9th to the first half of the 10th century CE in the South Moravian burial ground of Znojmo-Hradiště, to establish the association with incidence of dental caries, and to analyse the chemical element content of the enamel. The frequency and time of the development of enamel hypoplasia of the primary canine were established macroscopically. The chemical element content of the enamel was analysed via the EDX method. The incidence of LHPC is very high in this analysed collection in comparison with other Slavic populations. 45.59% individuals (n = 31) displayed at least one hypoplastic defect on their canines. Most individuals were 2-5 years old and more than a quarter of them had multiple hypoplasia. The most frequent shape of enamel defect is irregular. The difference between the defects originating in the perinatal period and those originating in the postnatal or prenatal period is statistically significant. Individuals with LHPC (localised hypoplasia of primary canines) have a higher presence of dental caries in primary teeth than individuals without LHPC, but without statistical significance. Individuals with LHPC have other hypoplasia on the primary teeth more often than individuals without LHPC. The EDX analysis shows the average value of the Ca/P ratio in Spectrum 1 to be highest in teeth with unsolid enamel (LHPC), decreasing to Spectrum 2 and subsequently to Spectrum 3. The concentration of phosphor is increasing from Spectrum 1 to Spectrum 3. Magnesium was most commonly present in Spectrum 1, and less often in Spectrum 2 and Spectrum 3 in mean concentration 0.27 and 0.39 at.%. Values of Mg content rise to on average 0.63 at.% on the base of hypoplastic defects. In agreement with the findings of Robinson et al. (1981), this might mean a lower density of enamel in the place of a hypoplastic defect. However, this cannot be argued clearly, because the difference in concentration could have been caused by diagenetic processes over the time that the samples lay deposited in soil. Sodium is found in our collection of teeth about as often in all three spectra in an almost identical mean concentration (0.51, 0.46 and 0.56 at.%, respectively).

The aim of this research is to study the effect of body overweight at birth (fetal macrosomia) on the processes of tooth eruption and tooth growth during the first year of life in children in the Kharkiv City (Ukraine) population. One of the research tasks is to examine the features of deciduous teeth eruption in children who were born with macrosomia with different values of the weight-height index at birth. Materials and methods. The medical records of the children born between 1977 and 2013 have been analyzed. The database has been collected in one of the Kharkiv City clinic. The Main Group is comprised of the medical records of the children (separately for boys and girls) born with fetal macrosomia. All the medical records of the Main Group have been divided into subgroups taking into account the gender and the harmonious (well-balanced) development coefficient. The Comparison Group is comprised of the medical records of the children also born within the normal term range, but with weight and height that correspond to the gestation age (fetal normosomia). To determine the average time of the first tooth eruption, as well as the deciduous teeth growth rate for each of the groups under the study, we have used the hypothesis about a linear dependence between the number of erupted teeth and the age of the child. The statistical data processing and verification of the consistency of this hypothesis is performed using the multiple linear regression analysis with the STATISTICA 6.0 software package (Multiple Regression module). The number of delayed eruption and premature eruption cases observed is calculated along with the corresponding confidence intervals for the significance level, p, of less than 0.05, taking into account the binomial distribution of the random variable. The results of the study indicate a slowed growth rate of deciduous teeth in children born with macrosomia, as well as an increased number of cases (by a factor of 2 to 4 times) of deviations in the timing of teeth eruption compared to regional norms. The smallest growth rate of deciduous teeth and the smallest number of teeth at the age of one year are registered in macrosomic boys and macrosomic girls with a long body and a relatively reduced birth weight, as well as in macrosomic girls with intrauterine obesity. The macrosomic girls with intrauterine acceleration with obesity at the background have the largest average tooth growth rate and the largest percentage of premature eruption cases among all subgroups. Conclusions. The somatometric features of fetal macrosomia suggest the influence on the number of teeth that erupt by a certain age. The data on the deviation from the generally accepted terms of teeth eruption in children born with macrosomia, can be the basis for developing new and improving existing prevention programs aimed at preserving dental health.

OBJECTIVES: The enamelin gene (ENAM) polymorphism (rs12640848) was recently associated with dental caries in primary teeth in Polish children. The aims of the present study were to prove this association in primary dentition and to find a possible effect of this variant on caries development in permanent dentition in Czech children. MATERIALS AND METHODS: This study comprised 905 Czech children. Totally, 187 children aged 2-6 years with primary dentition [78 healthy subjects (with decayed/missing/filled teeth, dmft = 0) and 109 patients with early childhood caries (ECC; dmft ≥ 1)] were included in this case-control study. In addition, 177 subjects aged 13-15 years without caries (DMFT = 0) and 541 children with dental caries (DMFT ≥ 1) in permanent dentition were selected from the ELSPAC study. Genotype determination of the ENAM polymorphism (rs12640848) was based on the TaqMan method. RESULTS: No significant differences in the allele or genotype frequencies between the caries-free children and those affected by dental caries were observed in both primary and permanent dentitions. CONCLUSIONS: Lack of association between the ENAM polymorphism (rs12640848) and dental caries in Czech children was detected. CLINICAL RELEVANCE: Although ENAM is considered as a candidate gene for dental caries, the presence of the ENAM variant (rs12640848) cannot be used as a risk factor of this multifactorial disease in the Czech population.
