Tooth eruption clock: A novel learning aid.

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.
