The purpose of this study was to develop a computer-assisted inference model for determining age based on dental development by orthopantomographs (OPT). Five experienced examiners (2 forensic pathology and 3 orthodontists) defined the degree of maturation of each of the permanent dental elements (superior and inferior hemi-arch) by 66 digitised OPT. Data set obtained was used as data base for un expert system designed on self learning that, by fuzzy reasoning, developed a set of complex algorithms in order to determine the age. The standard deviation (SD) of the age in such a way estimated compared to real ones was ±/10 months with 70% of reliability in rnales and +/- 8 months with 75% of reliability in females.

Abstract
The purpose of this study was to develop a computer-assisted inference model for determining age based on dental development by orthopantomographs (OPT). Five experienced examiners (2 forensic pathology and 3 orthodontists) defined the degree of maturation of each of the permanent dental elements (superior and inferior hemi-arch) by 66 digitised OPT. Data set obtained was used as data base for un expert system designed on self learning that, by fuzzy reasoning, developed a set of complex algorithms in order to determine the age. The standard deviation (SD) of the age in such a way estimated compared to real ones was ±/10 months with 70% of reliability in rnales and +/- 8 months with 75% of reliability in females.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
