The aims of the present study were to determine if primary teeth eruption and the presence of enamel defect are affected by low birth weight and prematurely of birth. Materials and Methods: The total subjects of (420) child aged 4 -24 months were included in this study, consisted of (210) prematurely born (<37 gestational weeks and birth weight < 2.500 Kg) children and 210 control children (≥40 gestational weeks and birth weight ≥ 2.500 Kg). Those children selected randomly the children who came to the primary health care centers with their mother for vaccination and the mothers asked to participate in this study. For each child, clinical exanimation was performed in dental chair. The criterion used for enamel defect to include various enamel hypoplasias, deficiency of enamel in the form of pits, grooves or other quantitative surface loss and enamel hypocalcifications and opacities. Data were analyzed using numbers, percentages, means and standard deviations. T -test, Z -test Chi -square (X 2 ) test were used for determining the differences concerning different variables. The differences were considered significant at p≤ 0.05. Results: There was no significant difference (p>0.05) between different genders numbers among in each age group for the preterm and control children. The results showed significantly (p<0.05) delayed eruption of the primary teeth in the prematurely born children as compared with the control children in all age groups except in 4 -6 months age group, also there was significantly higher percentages of enamel defect present in preterm children, than in control children in all age groups except in 4 -6 months age group. Conclusions: The findings indicated that the eruption of deciduous teeth was delayed and the percentage of enamel defect was significantly increased in prematurely born children.
Background: Pulpectomy is a root canal procedure for pulp tissue that is irreversibly infected or necrotic due to caries or trauma.
Aims: To evaluate the epidemiological aspects related to tooth intrusion during the primary dentition through examination and monitoring patients, as well as to find the correlation between the severity of intrusion and the consequences to the primary tooth itself that could occur. Materials and methods : This is a prospective observational study. Patients seen in the Pedodontics Clinic of College of Dentistry, University of Mosul who have suffered intrusive injuries of primary incisors. Patients included in this study should brought to Pedodontics Clinic with the first 24 hours from the occurrence of the accident. The children were assumed to be healthy and the intrusive teeth should not have previously received any pulp therapy or conservative restoration. Patients must have an initial X-ray; must have at least 12 months of monitoring; and their records must be adequately filled in. Results: The records of 39 patients with intrusion were analyzed and according to the inclusion criteria, 32 patients took part in the present study. The patients were between 2 and 4 years of age. There was slightly more girls (15, 53.6%) with dental trauma than boys (13, 46.4 %), but not reach a significant level (p> 0.05). All the intrusive teeth were upper central incisors. Concerning the severity of intrusion; mild intrusion was 7 (21.9%) teeth, moderate intrusion was 20 (62.5%), while severe one was 5 (15.6%) teeth. Conclusions: In aiming to minimize developmental disturbances in the permanent dentition, the most effective methods are firstly to obtain an exact diagnosis, then to provide correct first-aid treatment and finally to perform regular follow ups.
