Abstract

Aims: To establish the different reasons of primary and permanent teeth extraction and the most frequent tooth type extracted among children attending the pedodontic and preventive dentistry clinic at Collage of Dentistry ,Mosul University. Materials and Methods: Out of the 375 pediatric patients aged 3–12 years–old attending pedodontic and preventive dentistry clinic, 130 child patients were selected for this study. The teeth were examined carefully, the tooth that needed to be extracted was recorded to determine the cause of extraction for each tooth according to the criteria gathered and modified from the following researchers, Cahen et al; Kay and Blinkhorn and Cawson. Results: Statistical results showed highly significant difference at p < 0.001 between primary and permanent teeth and the cause of tooth extraction, as extraction due to caries was the main reason for primary tooth extraction while extraction for orthodontic treatment was the major cause for permanent tooth extraction. The first premolar recorded 43.6% this result showed highly significant difference at p < 0.001 compared with other permanent teeth to be extracted, while the first primary molar registered the higher value as an extracted primary tooth type (35.6%) with high significant difference at p < 0.001. Conclusion: Although caries and it is sequelae were the most common causes of premature loss of a primary tooth, an increasing need for tooth extraction for orthodontic treatment in this population of children was observed.

Highlights

In the management of the child dental patient, efforts are geared toward the preservation of both primary and permanent dentition; this is because the dentition is important for stimulating the development of the dental arches, maintaining normal occlusal relationship, and playing a role in speech development (1)
Tooth extraction is commonly a treatment consideration in the orthodontic management since the primary aims of orthodontic treatment in the mixed dentition are to correct dental arch irregularities, occlusal and jaw relation abnormalities and to eliminate functional interferences; these may be classified as preventive which means the elimination of factors that may lead to malocclusion or interceptive that implies to the corrective measures which may be necessary to prevent a potential irregularity from progressing into a more sever malocclusion (4)
Table (2) shows that the number of patients treated by extraction of one or more of their teeth were 130 patients which were less than the total number of the examined sample 225

Summary

Introduction

In the management of the child dental patient, efforts are geared toward the preservation of both primary and permanent dentition; this is because the dentition is important for stimulating the development of the dental arches, maintaining normal occlusal relationship, and playing a role in speech development (1). At 5 years of age 31– 40 % of boys and 16–30 % of girls would have suffered dental trauma, such injuries in the primary dentition may interfere with the normal development of the permanent dentition so they are usually managed by extraction (6). Variations in the time of primary teeth exfoliation are frequently observed in the child patient, normal tooth mobility that causes child discomfort due to interference with the functional role of the adjacent and opposing teeth may indicate that the associated tooth is at the exfoliation time and can be extracted (8). Other causes for tooth extraction are teeth that are affected by periodontal diseases, supernumerary teeth, and natal and neonatal teeth (9)
