Parents consider tooth eruption as an important event in the child's development, and they have often shown their concern about the timing of this eruption. Mostly the information on the age of permanent teeth emergence used in clinical and academic situations in Pakistan is based on American and European standards. However, it has been suggested in the literature that standards for tooth emergence should be derived from the local population in which they are to be applied because factors related to emergence may vary considerably in both dentitions. Many studies are conducted in different population and among different ethnic groups all over the world. However, there is no known study reported from Pakistan, except for the one on primary teeth and one on permanent teeth conducted only for boys in pre-partition time (before 1947). Hence there was a vital need to conduct such a study for the Pakistani population. This book shows the norm for time and sequence of eruption of permanent teeth for Pakistani children.
