A four-level index of oral functional capability (IOFC) is measured in old olds.
It has been claimed that occluding pairs of natural teeth are strongly correlated with oral functional impacts [ 5].
In addition to poor oral health, dental neglect is associated with increased oral functional limitations and social and physical disabilities [ 3].
The index of oral functional capability is calculated in a four point capability level scale: normal, slightly reduced, considerably reduced, and none.
Amongst many other factors, oral posture is dependent not only on muscular forces but also on biomechanical conditions, including the formation of secluded oral functional compartments which, in the past, has received little attention in the literature.
In the present report, a hierarchical classification system [ 8, 12], which was designed on the basis of the assumption of different qualities for different tooth types and their roles in a functional dentition, was used to describe oral functional status.
In addition, socioeconomic status as measured by income, perceived oral functional status as captured by chewing ability and self-reported susceptibility to periodontal disease were also important predictors of oral health-related quality of life.
Calculations of several indices are performed on basis of the recorded data: attachment loss (AL), basic erosive wear examination (BEWE), bleeding on probing (BOP), community periodontal index (CPI), oral functional capability (IOFC), MFS/T index, molar incisor hypomineralization (MIH), papilla bleeding index (PBI), root caries index (RCI), and sense of coherence total score (SOC).
