Chronology of tooth eruption is the most preliminary and crucial topic which is covered in the undergraduate syllabus of the dental curriculum. Eruption of permanent and primary teeth follows a particular time sequence. Both maxillary and mandibular arch has similar number of teeth, beginning from central incisors to molars. The pattern of eruption differs slightly between maxillary and mandibular arch. Remembering the years or months in a numerical manner is the usual way by which a student learns the eruption chronology. Eruption clock is a specially designed learning aid, which makes this teaching-learning process a lot easier, effective and practical.
牙齿萌出的时间顺序是牙科课程本科教学大纲中最基础且关键的主题。恒牙和乳牙的萌出遵循特定的时间顺序。上颌和下颌牙弓的牙齿数量相似，从中央门牙到磨牙依次排列。上颌和下颌牙弓的萌出模式略有不同。学生通常以数字方式记住年份或月份来学习萌出时间顺序。萌出时钟是一种专门设计的学习辅助工具，它使这个教学过程变得更加轻松、有效和实用。
