It has been known for over 25 years that treatment with oral tetracyclines can permanently stain children’s teeth1 yet these drugs are still needlessly being prescribed for children. In 1982 over 75,000 prescriptions for a liquid tetracycline preparation were dispensed, most of which were probably for children; up to one third of paediatric patients have been affected,2–6 although the proportion has fallen over the last 10 years.7 Even a short course of tetracycline can stain both the permanent3,8 and deciduous teeth9 a disfiguring greyish-brown or yellow colour. Children are at risk from the 14th week in utero, when calcification of deciduous teeth begins, to their 7th year when calcification of the permanent teeth is complete. Whether tetracyclines produce enamel hypoplasia10 or promote caries11 is disputed.12

Abstract Linear enamel hypoplasia (LEH) is treated as a nonspecific indicator of stress, but even so, many authors consider it the most reliable tool stress in anthropological research. Its analysis allows the reconstruction of health related to the socio-economic status of the group. This study documents and interprets patterns of LEH in Żerniki Górne (Poland), a settlement which was functional in the Late Neolithic and the Early Bronze Age. We examined two successive cultures: the Corded Ware Culture (CWC; 3200-2300BC) and the Trzciniec Culture (TC; 1500-1300BC). In total, there were 1486 permanent teeth (124 adult individuals). The frequency of LEH in the examined cultures shows a small rising trend. In these series from Żernik Górne, males showed a higher occurrence of LEH (16.5%) than females (13.4%). The earliest LEH appeared at similar ages at about 2.0/2.2 years and the last LEH occurred at about 4.2 years of age in both cultures. However, it is worth noting that periods associated with physiological stress were more common but not very long (four months on average) in the CWC. Longer stress periods (nine months on average) were associated with the TC.

Enamel hypoplasia is the most common disease of hard tooth tissues of non-carious origin emerging before their eruption. It develops as a result of a delayed and perverse function of ameloblasts leading to the violation of the processes of formation and mineralization of tooth protein structures. The clinical manifestations of enamel hypoplasia are spots, defects in the form of pits, cup-shaped depressions, grooves on various surfaces of child’s teeth. The work is devoted to a comparative investigation of microstructural and compositional features of intact and hypoplastic enamel in children’s permanent teeth using analytical scanning electron microscopy with energy-dispersive X-ray spectroscopy. The hypoplastic enamel is enriched in organic substance and has an irregular structure without keyhole-shaped prismatic structure. Mineral deposition is indicated for hypoplastic enamel including hydroxyapatite with globular structure and calcite and halite, which might have been caused by the violation of extracellular local environment probably due to the enamel hypoplasia development.

Objective: This retrospective study aims to evaluate the prevalence of dental anomalies in permanent teeth as a result of a trauma concerning the predecessor primary teeth. Study design: A total of 241 records of children (118 males and 123 females, mean age 3.62 ± 1.40) affected by trauma on primary teeth were analyzed. All patients were recalled to evaluate the status of the permanent successor teeth by clinical and radiographic investigations. Results: Out of 241 patients, 106 patients (for a total of 179 traumatized primary teeth) presented at the recall. Dental anomalies on successor permanent teeth were detected in 21 patients (19.8%), for a total of 26 teeth (14.5%) and 28 anomalies. Anomalies of the eruptive process were the most observed disturbances (60.7%), followed by enamel hypoplasia (25%) and white spots (14.3%). A higher percentage of anomalies on permanent teeth was observed when trauma occurred at an age less than 36 months (38.5% of cases). Intrusive and extrusive luxation were related with the most cases of clinical disturbances in the successor permanent teeth. Conclusions: The results of this study highlight the risk of dental anomalies after a trauma in primary dentition, especially in early-aged children and in case of intrusive luxation.

AbstractWe report the frequencies of linear enamel hypoplasia (LEH) and, specifically, pitting enamel hypoplasia (PEH) defects in the teeth of Paranthropus robustus, for comparison with four other South African hominin species and three extant nonhuman primate species. Unlike LEH, the lesser known PEH is characterized by multiple circular depression defects across a tooth crown and is often difficult to interpret in terms of developmental timing and etiology. Teeth in all samples were examined macroscopically with type, position and number of defects recorded. Frequencies of teeth with LEH vary among hominin species, but the differences in PEH are considerable. That is, P. robustus has much higher rates of pitting defects, with 47% of deciduous teeth and 14% of permanent teeth affected, relative to 6.7% and 4.3%, respectively, for all other hominin teeth combined; none of the extant primate samples evidence comparable rates. The defects on P. robustus molars are unlike those in other species, with entire crowns often covered in small circular depressions. The PEH is most consistent with modern human examples of amelogenesis imperfecta. Additionally, the defects are: 1) not found on anterior teeth, 2) uniform in shape and size, and 3) similar in appearance/severity on all molars. A possible reason for this form of PEH is as a side effect of selection on another phenotype that shares the same coding gene(s), i.e., a genetic origin. Recent research on the ENAM gene provides one such possibility. Paranthropus likely underwent rapid evolution in the ENAM loci, with changes in this gene contributing to larger posterior teeth and thicker enamel. This same gene is associated with amelogenesis imperfecta; therefore, pleiotropy effects, relating to high selection on this gene during Paranthropus evolution, could have yielded this unique condition.

Objective: assessment of dental caries intensity in children with disturbances in tooth formation living in radiologically contaminated territories as a result of the Chornobyl NPP accident. Materials and methods. Children aged 6-14 years old (n = 1470) suffering from disturbances in tooth formation (DTF) with the residents of radiologically contaminated territories (n = 528) among them were enrolled in the study. The DTF subtypes were assayed, namely the systemic enamel hypoplasia (SEH) and molar incisor hypomineralisation (MIH). Personal radiation history was recorded. Intensity of caries and caries of surfaces in the mixed (i.e. transitional) occlusion (df+DMF, dfs+DMFS coefficients) and permanent occlusion (DMF, DMFS coefficients) was identified. Results. Caries intensity in the exposed children suffering DTF with mixed and permanent dental occlusion was significantly higher vs. either in children exposed to ionizing radiation with no DTF or in the control group (р < 0.001, р < 0.001 and р < 0.05, р < 0.001 correspondingly). The highest caries intensity of the permanent teeth was revealed in the residents of contaminated territories suffering SEH (6.95 ± 2.3) vs. cases of MIH (5.68 ± 1.97) as a result of nonsymmetrical teeth involvement. Conclusions. The highest values of df+DMF, dfs+DMFS coefficients were diagnosed in children with a mixed dental occlusion aged 6-14 years old living on territories contaminated as a result of the ChNPP accident as compared to the not exposed subjects and control group (7.2 ± 2.07 and 8.98 ± 2.4, р < 0.001). A very high intensity of caries and surface caries of permanent teeth (DMF = 6.79 ± 2.34, DMFS = 8.69 ± 2.75, р < 0.001) was established in children exposed to ionizing radiation and suffering DTF. Such a high intensity may be due to the impact of a set of negative factors including the ionizing radiation in low doses and peculiarities of economic component of social status of study subjects, namely the unbalanced diet. In case of permanent occlusion the intensity of caries and caries of tooth of in children survived after the ChNPP accident and suffering SEH was significantly (р < 0.05) higher compared to the persons suffering MIH. Key words: children, caries, disturbances in tooth formation, systemic enamel hypoplasia, molar-incisor hypomineralization, ionizing radiation, ChNPP accident.

Main Culprit

Turner’s tooth is a form of enamel hypoplasia. Periapical pathology of the primary tooth is the main culprit behind the enamel deficiency in the permanent tooth. The altered tooth is called a Turner’s tooth. Color of the affected tooth varies from focal areas of white, yellow, or brown discoloration to extensive hypoplasia which can involve the entire crown. The crown of the permanent teeth develops mainly from six months and extends upto fifteen years. The part of the crown which gets damaged is directly related to the location of the ameloblastic activity at the time of damage. Therefore, we are here discussing the case of a seven year old boy which was reported to be the case of turner’s tooth hypoplasia.

AbstractThe enamel defects, hypoplasia and hypo mineralization, are classified as dental anomalies of structure, being frequently found in deciduous and permanent dentitions, since the permanent teeth and second deciduous molars finish their total mineralization after the age of three. The aim of the present study was to identify the presence of hypo mineralization and/or enamel hypoplasia and to associate it with respiratory problems in infant patients. Of the 90 patients evaluated, it was found that 23 male children (57.5%) and 22 female children (44%) had defects in the structure of tooth enamel. Most children were born by cesarean operation (64.4%), with no complications during birth (90.0%), 12.2% of children had dental anomalies (agenesis, ectopic canine, ankylosis, fusion, conoid tooth, and macrodontia, only 7 children showed an association between dental anomalies and enamel defects. Regarding respiratory problems that occurred up to 3 years of age, 38.9% had an episode of asthma, bronchitis, sinusitis, rhinitis, or pneumonia, and 55% had similar results at the current age. There was a positive association (Chi-square tests) between the presence of changes in the structure of tooth enamel and the presence of respiratory problems up to 3 years of age (p <0.001). It is concluded, therefore, that the presence of respiratory problems in early childhood, can interfere in amelogenesis, providing disturbances for the formation of normal enamel, causing defects or irregularities in the surface of the dental enamel, such as hypoplasias and hypo mineralization. Keywords: Dental Enamel Hypoplasia. Dental Enamel. Tooth Abnormalities. ResumoOs defeitos de esmalte, hipoplasia e hipomineralização, são classificados como anomalias dentárias de estrutura, sendo encontrados com frequência nas dentições decídua e permanente, já que os dentes permanentes e segundos molares decíduos finalizam sua total mineralização após os três anos de idade. O objetivo do presente estudo foi identificar a presença de hipomineralização e/ou hipoplasia de esmalte, e associá-la com problemas respiratórios no paciente infantil. Dos 90 pacientes avaliados, constatou-se que 23 crianças do gênero masculino (57,5%) e 22 do gênero feminino (44%) apresentaram defeitos na estrutura do esmalte dentário. A maioria das crianças nasceu de parto cesária (64,4%), sem complicação no parto (90,0%), 12,2% das crianças apresentaram anomalias dentárias (agenesia, canino ectópico, anquilose, fusão, dente conóide e macrodontia), somente 7 crianças apresentaram associação entre anomalias dentárias e defeitos de esmalte. Em relação à problemas respiratórios ocorrido até aos 3 anos de idade 38,9% apresentaram algum episódio de asma, bronquite, sinusite, rinite ou pneumonia e 55% apresentaram resultados semelhantes na idade atual. Houve associação positiva (Testes Qui Quadrado) entre a presença de alterações na estrutura do esmalte dentário e presença de problemas respiratórios até os 3 anos de idade (p<0,001). Conclui-se, portanto, que a presença de problemas respiratórios na primeira infância, podem interferir na amelogênese, proporcionando distúrbios para formação do esmalte normal, causando defeitos ou irregularidades na superfície do esmalte dentário, como hipoplasias e hipomineralizações.
