Evaluation of root development of mandibular first molar of children (6-12) years old visiting P.O.P. department College of Dentistry/ Hawler Medical University.

Abstract

Background and objective: With FPMs between the ages of 6 and 12, the detection of open apex in some children at age 12 underlines the necessity for investigation prior to treating a deep carious lesion.Pulpal involvement was considered before the surgery began. The genesis of the roots is complete. Dentists are urged to conduct a comprehensive clinical examination, get diagnostic radiographs, and adhere to case-specific treatment protocols before attempting to treat FPMs in children, even those as young as 12 years old. This would reduce the likelihood of treatment mistakes, which might hinder the extraction of FPMs or cause unacceptable damage. Method: Dentists in the Paediatric Dentistry Department at Hawler Medical University saw all the children in the sample, and they were all in good health condition. This research evaluated the crown and root development stages of lower FPMs on both sides, as found by Demirjian et al. (1973). Information was collected in Excel 2017 for use in making charts and tables. Mean and standard deviation values. The T-test, either paired or unpaired, with a p-value of 0.05 serving as the threshold for statistical significance. Results: The findings showed that there was a total of 250 OPGs, with 130 belonging to females and 120 belonging to boys. The ages of the children that were considered for inclusion in the sample varied anywhere from six to twelve years old. In a sample of 12, the first molar in the mandibular region had the greatest percentage of AC (84.4%). Conclusions: The discovery of open apex in some children at 12 confirms the need for inquiry before treating a deep carious lesion in FPMs between the ages of 6 and 12. we evaluated the potential risk of pulpal involvement during this period. Before treating FPMs in children, even those as young as 12, the dentists were advised to do a thorough clinical examination, get diagnostic radiographs, and follow specific treatment procedures based on clinical instances.
