ChangesDescriptionAnalysis By
AttritionWearing down of incisal or occlusal surface due to masticationAppreciable macroscopically as well as microscopically
PeriodontosisRetraction of gum margin and loosening of toothAppreciable macroscopically as well as microscopically
Secondary DentinSeen within the pulp cavity, as a result of aging/as a reaction to caries and periodontosisAppreciable microscopically
Cementum AppositionAt and around the root of the toothAppreciable microscopically
Root ResorptionInvolves both cementum and dentinAppreciable microscopically
Root TransparencyThe best criteria for age estimation. Mostly seen on the ground section of the tooth. This occurs in the root, from below upwards in the lower jaw, and from above downwards in upper jaw teeth due to rarefaction of the dentin tissue. Assessing the transparency and ages is estimated using a regression line prepared by studying the transluency of known ages.
