Background: Tooth development shows less variability in relation to chronological age. Tooth development
is widely used to assess maturity and predict age. So, dental tissues can be used as a better aid for estimating
age. Radiography plays an important role in humane age determination. There are five common methods
to determine age using radiographs: Gleiser and Hunt (1955); Demijiran et al (1973); Gustafson and Koch
(1974); Harris and Nortje (1984); Kullman et al (1992). Nolla’s method (1960) was one of the various
method used in age determination using radiographs. The aim is to estimate the age using Nolla’s method
of forensic age estimation.
Materials and Method:The present study was conducted on 20 selected individuals(10 males and 10
females) between age 9-17. Dental age assessment was done using OPG. The radiograph were compared
with the Nolla’s chart (fig-1) and dental age was assessed using age norms for upper and lower teeth including
third molars proposed by Nolla. The chronological age and dental age obtained using Nolla’s method was
later subjected to statistical analysis.
Results: There is no significant difference between chronological age and estimated age with Nolla’s method
both in males and females i;e is ‘p’ value is not significant in both males and females (.161 in females and
.757 in males).
Conclusion: Nolla’s method of age determination was accurate in both males and females.No statistical
significance was found between chronological age and estimated age for males and females. Hence Nolla’s
method can also be used in forensic dentistry.
