Abstract
Background The timing of eruption of permanent teeth can be a precious help to the pediatric practitioner in identifying an appropriate treatment plan. Usually, it presents a more precise sign of an early or late growth of the child. Aims It is to determine whether the timing of the permanent teeth eruption in Lebanese pediatric population can be considered as standard Lebanese values, since no other study was previously performed. Materials and Methods A cross-sectional study is conducted, and the clinical emergence data are collected for a sample of 2317 Lebanese children aged between 5.5 years and 13 years (1129 girls and 1188 boys) from different socioeconomic groups in rural and urban communities spread over different regions in Lebanon. The study investigates dental emergence patterns. Results Statistical analysis is performed with the SPSS Software. A confidence interval of 95% and significance level of 5% are adopted. The trend is for males to begin their permanent teeth eruption later than girls. Emergence of all permanent mandibular teeth is earlier than maxillary ones. Symmetry is found between the right and left teeth in the maxilla, as well as in the mandibula. Conclusion In this study, the results indicate that premolars and second permanent molars erupt earlier in the Lebanese children compared to children of other countries reflected in several studies.
Highlights
Timing of teeth eruption is useful to the pedodontist and the orthodontist since it provides information from the standpoint of physiological growth and development. e skeletal age and dental age can be applied to assess the degree of physiological maturity of a growing child, as well [1].e age determination of an individual by examination of teeth is an accepted method in the legal system.In forensic dentistry, the age of subjects, with unknown birth record, can be calculated by using the emergence time of permanent teeth [2]
E median age for eruption of permanent teeth in Lebanese children is shown in Table 2. e mean age of eruption of permanent teeth is at 76.7 months for the first permanent upper right molar (#16), and it ends at 132.9 months for the second permanent upper right molar (#17)
For tooth #17, the mean age of eruption is 132.9 months compared to 132.5 months for tooth #27. e mean age of eruption is at 123.0 months for tooth #15 and at 123.8 months for tooth #25
Summary
Timing of teeth eruption is useful to the pedodontist and the orthodontist since it provides information from the standpoint of physiological growth and development. e skeletal age and dental age can be applied to assess the degree of physiological maturity of a growing child, as well [1].e age determination of an individual by examination of teeth is an accepted method in the legal system.In forensic dentistry, the age of subjects, with unknown birth record, can be calculated by using the emergence time of permanent teeth [2]. Several studies have reported differences in permanent teeth eruption between ethnic groups [4,5,6,7,8]. E purpose of the present study is to ascertain and to evaluate the timing of eruption of permanent teeth in Lebanese population and to compare with other groups.
