Objective:
The aim of the present study was to check the reliability and applicability of new proposed tooth numbering system (TNS) for primary teeth that will aid the dentist to overcome the disadvantages of existing TNS and enable to note the primary teeth in an easier and more precise way.
Study Design:
This observational questionnaire survey was conducted in an institution consisting 11 questions in English format. Four hundred samples were randomly selected which included under graduates, postgraduates, and faculty. Self-structured questionnaires were given in order to assess the reliability and applicability of the new proposed TNS. Data obtained were subjected to statistical analysis. Chi-square test was used to compare the responses between different study groups, and P value was set at P < 0.05.
Results:
According to the participants, the new TNS maintains the anatomical midline, easily readable, written and typed though required extra concentration. It is easy to converse and can be followed by beginners. It does not require extra timing and can be used routinely. With mixed dentition, it does not take more time, but there are chances of confusion or overlap while recording.
Conclusion:
The new Havale's Alphaneumarical Dental Notation system can be used routinely by undergraduates and postgraduates as well as clinicians and can apply or follow the system in regular dental practice.
