Do the intracanal medicaments affect the marginal adaptation of calcium silicate-based materials to dentin?

Background/purpose: In order to prevent reinfection of the pulp canal space and dressing for regenerative purpose, the coronal seal should have a perfect marginal adaptation. Mineral trioxide aggregate (MTA) and Biodentine are among the most popular sealing materials. These are commonly used in combination with antibiotic medicaments, to ensure disinfection. Aim of the present study was to evaluate the effect of 3 different medicaments on the marginal adaptation of MTA and Biodentine to the dentin. Materials and methods: Teeth were divided into 4 groups (n = 20) that were treated with the following medicaments; triple antibiotic paste (TAP), double antibiotic paste (DAP), a calcium hydroxide (CH) and a control group. The specimens were then assigned into two subgroups (n = 10), which received a coronal barrier of MTA or Biodentine. The specimens were scanned using an ex vivo micro-CT scanner. The data were statistically analysed using one-way ANOVA and the unpaired Student's t-test (P TAP > Control > CH. In the Biodentine group, the percentage of voids was determined in the following order: TAP 65 DAP > CH > Control. Significantly lower percentage of voids was observed in the CH-medicated specimens in the MTA group when compared to all test groups (P = 0.04). Conclusion: The application of CH as an intracanal medicament reduced the void occurrence between the ProRoot MTA and root dentin. However, TAP and or DAP decreased the marginal adaptation in both ProRoot MTA and Biodentine

Congenital syphilis with multiple fractures

A 67-day-old male infant with the multiple fractures in his bones due to congenital syphilis was presented. The diagnosis was confirmed serologically. The baby had also the non-specific intrauterin infection signs with the atypical mononuclear cells in his blood smear and a possible syphilitic renal disease. His symptoms markedly diminished after penicillin therapy

EFFECTS OF INDOOR ENVIRONMENTAL-FACTORS ON RESPIRATORY SYSTEMS OF CHILDREN

WOS: A1994NL79800012PubMed ID: 8015025Effects of indoor environmental factors on children's respiratory system and pulmonary function tests were investigated in this study. A total of 617 primary school children aged between 9-12 years were included. A standard questionnaire, which includes questions about respiratory symptoms and illness, indoor environmental determinants, family history of respiratory diseases, and smoking habits of the parents, was sent to homes of all children and information was obtained from parents. Children with a family history of asthma, bronchitis, or other chest troubles suffered morning and day/night coughs, shortness of breath, wheezing and asthma, bronchitis, or pneumonia more frequently. Children whose mothers smoked complained of blocked-runny nose and sinusitis more frequently. Pulmonary function levels were diminished in passive smokers and in children whose houses were heated by a wood-burning stove. As a result, passive smoking, using a wood-burning stove for heating, and family history of respiratory diseases are to be considered risk factors for the respiratory system

The modification in measles vaccination age as a consequence of the earlier decline of transplacentally transferred antimeasles antibodies in Turkish infants

WOS: A1996VY85900014PubMed ID: 8982627The maternal antibodies are gradually decreased at 9 to 12 months in infants. We determined the elimination period of maternal measles antibodies in 34 infants whose mothers had had a history of natural measles previously. Seropositivity rates at sixth and nine months of age were found to be 61.8% and 3.4%, respectively. The very low passive antibody at nine months of age may suggest the measles vaccination could be carried out earlier than just before the critical age of antibody level

The effects of long term use of inhaled corticosteroids on linear growth, adrenal function and bone mineral density in children

PubMedID: 16045858In this study we aimed to investigate the long term effects of inhaled steroids on linear growth, adranal function and bone mineral density. Thirty children with moderate asthma were randomly divided into two groups. Fifteen children (8 boys, 7 girls mean age; 10.6 ± 2.1) were treated with budesonide (group 1), and 15 (9 boys, 6 girls, mean age; 9.6 ± 2.4). with fluticasone propionate (group 2). Control group included 30 children. Anthropometric assessment, symptom and medication scores, pulmonary functions, bone mineral density, serum and urine cortisol levels and ACTH stimulation test were evaluated at the beginning of the study and after one year period. Symptom and medication scores, pulmonary functions improved significantly in both groups (p < 0.05). The mean annual growth was similar in group 1 and 2 and control group. Bone mineral density was comparable with control group at the beginning of the study and after one year. Mean serum cortisol level diminished at the end of the therapy but no significant differences were found between the initial and end values in respect to urine cortisol levels and cortisole/creatinin ratio. Of three groups ACTH stimulation test revealed that there were no significant difference between study and control groups. In conclusion, although we did not observed any side effects of inhaled corticosteroids we suggest that children treated with inhaled corticosteroids for a long time should be followed closely with respect to side effects

T-lymphocyte subpopulations of children with atopic asthma

The immune status of thirty-one patients with moderate asthma aged between 4-15 years old was compared with twenty age and sex matched healthy subjects. The peripheral blood white blood cell (WBC), total lymphocyte counts, B lymphocyte, CD3+ T lymphocyte and CD4+ T lymphocyte were similar and in normal range in both groups. The mean of T lymphocyte (E rosette) value was 58.09% in asthmatic children and 60.10% in the control group (p > 0.05). CD8+ T lymphocyte percentage was significantly lower in asthmatic children than the controls (p < 0.001). The ratio of CD4+/CD8+ T lymphocytes was 1.93 in asthmatic children and 1.42 the control subjects, and there was a significant difference between the two groups (p < 0.001). Although the mean of the IgE level was found to be higher in children with asthma when compared with the control group (1046 ± 862.5 iu/ml vs 173.8 ± 96.8 iu/ml, p < 0.001) no statistically significant difference was detected between the mean IgA, IgM and IgG values of both groups. We concluded that CD8+ T lymphocyte level is low in asthmatic children
