{"title":"Enamel hypoplasia in prematurely-born children: a scanning electron microscopic study.","authors":"W K Seow, S Perham","doi":"","DOIUrl":"","url":null,"abstract":"Although the enamel defects of low birthweight prematurely-born children have been well investigated clinically the ultrastructure has not been studied in detail. Using scanning electron microscopy this investigation examined the enamel surface of 4 representative teeth from a group of exofoliated teeth from prematurely-born, very-low birthweight children compared to an equal number of control teeth from normal birthweight children. The results showed that all 4 teeth from the prematurely-born group had enamel defects at the ultrastructural level even though the defects were evident only macroscopically in 2 teeth. By contrast all the control teeth from normal children did not show abnormalities of surface structure. Thus this investigation further confirms that birth prematurity and low birthweight adversely affect the activities of ameloblasts. Previous clinical investigations have reported that prematurely-born children show high prevalences of enamel hypoplasia of around 20-100%. The etiological factors involved in the pathogenesis of enamel defects are unclear, but are likely to be related to many systemic illnesses occurring during the neonatal period. These include respiratory distress syndrome, hyperbilirubinemia, maternal diabetes as well as neonatal rickets. Furthermore, Seow et al. (1989) showed recently that deficiency of calcium and phosphate mineral in the neonatal period is related directly to enamel hypoplasia in very-low birthweight, prematurely born children. In addition to systemic factors, local factors such as laryngoscopy and endotracheal intubation have also been implicated in the etiology of enamel hypoplasia in these children. While the enamel defects have been well studied at the clinical level, there is a paucity of information on the ultrastructural nature.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":76658,"journal":{"name":"The Journal of pedodontics","volume":"14 4","pages":"235-9"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13253761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to evaluate, whether the transition from the primary to the permanent dentition is accompanied by any significant changes in several clinical and microbiological parameters commonly used as predictors of caries activity. Sixty children and adolescents, aged 3 to 16, participated in the study and according to age were assigned to 4 different dentition groups (primary, early mixed, late mixed, permanent). The results indicate, that there is a significant decrease in salivary Streptococcus mutans and Lactobacillus spp. counts in the late mixed dentition group compared to the primary and the early mixed dentition group. Furthermore, in the permanent dentition group the stimulated salivary flow rate was significantly higher than in all other groups. Differences regarding plaque score and salivary buffering capacity were not significant for all groups examined. It is concluded, that the transition from the primary to the permanent dentition in general is accompanied by significant, yet temporary decline in the numbers of caries-associated microorganisms, reflecting marked differences in caries incidence and activity, previously reported by other authors.","PeriodicalId":76658,"journal":{"name":"The Journal of pedodontics","volume":"14 3","pages":"141-3"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13237486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to assess (1) dental knowledge, attitudes, and health behavior among the mothers of children in first grade, and (2) dental knowledge and attitudes of schoolteachers, and their involvement in health education. Before the children were enrolled in the program 187 mothers (response 76%) were interviewed. Self-administered questionnaires were used to collect data on schoolteachers (n = 135, response 695). Most of the mothers (74%) answered that dental caries is caused by sweets/candy; the role of bacteria was mentioned by 9%. Half of the mothers were aware of the harmful effect of sugary drinks, and 50% knew about the preventive effect of fluoride. Knowledge about causes and prevention of periodontal disease was diffuse. According to the mothers, 68% of the children were in need for dental treatment; 37% were seen by a dentist once a year for symptomatic reasons, and 49% brushed their teeth at least twice a day. Sixteen-percent of the mothers helped their child in brushing every day. Sugar consumption among mothers and children was high, e.g. 66% of the children had chocolate bars and 44% had soft drinks several times a day. The level of dental knowledge was higher among teachers than mothers; the mothers were mostly informed through television/radio, while teachers had received information from various sources, including the dentists. The teachers responded positively to prevention of dental diseases among children and should be considered key persons in dental health education. For the Kuwaiti children and the mothers the active involvement principle, group presentations, and one-to-one communications are recommended for the school based dental health program.","PeriodicalId":76658,"journal":{"name":"The Journal of pedodontics","volume":"14 3","pages":"158-64"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13236639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
