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.
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.
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.
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.
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.
恒牙萌出的时间可以为儿科医生确定合适的治疗计划提供重要帮助。通常，它更能准确地反映儿童生长的早期或晚期。
确定黎巴嫩儿科人群的恒牙萌出时间是否可以作为标准的黎巴嫩值，因为之前没有进行过其他研究。
进行了一项横断面研究，收集了来自黎巴嫩不同地区农村和城市社区的不同社会经济群体的 2317 名 5.5 至 13 岁（1129 名女孩和 1188 名男孩）黎巴嫩儿童的临床萌出数据。该研究调查了牙齿萌出模式。
使用 SPSS 软件进行统计分析。采用 95%置信区间和 5%显著性水平。趋势是男性恒牙萌出比女性晚。所有下颌恒牙的萌出都比上颌早。上颌的左右牙齿以及下颌的左右牙齿之间存在对称性。
本研究结果表明，与其他几个研究中反映的其他国家的儿童相比，黎巴嫩儿童的前磨牙和第二恒磨牙萌出更早。
