Evaluation of developmental delay in infants who came in for 6th month vaccination in Isfahan city health centers

Development delay in one of the most common causes of conferring the pediatric neurologist. The main part of neurological growth and development occur in the first two years especially in the first 6 months of life. Metabolic or skeletal diseases are important causes of developmental delay. Early diagnosis of deviance from the normal diagram of development in lower ages is important. Specific ages and stages questionnaires [ASQ] for 6 months was completed in the health centers of 800 infants conferring for their vaccination in Isfahan and the retest was performed at 24 months of age by ASQ and then these two questionnaires were compared. 10.5% of the infants were delayed in at least one domain. At 24 months, 38.4% of them remained delayed; 21.1% in one domain, 9.6% in two domains, 3.8% in four domains and 3.8% in five domains. Of the children who had problem in communication, 20%; in gross motor, 25%; in fine motor, 20%; and in problem solving, 30% remained delayed. In the personal social domain, none of the delayed children at 6 months remained delayed at 24 months. ASQ is feasible, inexpensive, easy to use and was appreciated by the parents. It can be used as a screening test for detection of developmental delay in lower ages, but its results must be followed by other standard tests or diagnostic tools

effect of intra canal fluids on the apical seal of root canal fillings using AH26 and rosen sealers

One of the main objectives of root canal treatment is to achieve a suitable and 3-dimensional seal in order to prevent tissue fluids and microorganisms from re-entering the root canal system. The aim of this study was to determine the effect of intracanal moisture on the apical seal during root canal obturation using Rosen and AH26 sealers. Sixty-four teeth were chosen according to the inclusion criteria: mature apices, straight canals, no intra/extra-resorption or calcification. The root canals were prepared and randomly divided into six groups, after removing the crowns. Two different sealers, AH26 and Rosen, were chosen and the teeth were filled using the lateral condensation technique in three different settings: dry canal, presence of blood and 2/5% hypoclorite in the canals. All specimens were immersed in methylene blue solution, rinsed throughly and dried. The roots were cut longitudinally into two halves. For dye volumetric measurements, all samples were immersed in 65% nitric acid and the volume of the penetrated dye was measured by a spectrophotometer. Two-way ANOVA was used to compare the leakage of the dye in the study groups. The amount of dye leakage was significantly lower in the AH26 groups [P<0.001]. There was no significant difference between the three clinical settings in the AH26 and Rosen groups [P=0.857]. If the basic obturation principles are carefully administered during root canal filling, intracanal moisture could not affect apical seal, especially when AH26 is employed as a sealer instead of Rosen
