The present study was carried out to compare the ability of different
methods of periodontal assessment to identify those subjects in a popu
lation who had suffered the worst periodontal breakdown. Comparisons w
ere made between full mouth approximal attachment loss (GAL) assessmen
t and methods relying on pocket probing depth (PPD) evaluation or on p
artial recording of CAL or PPD. Both of the latter types of assessment
are commonly used in epidemiological surveys. 202 workers at an elect
ronics factory aged between 20 and 40 yr were examined for approximal
PPD and GAL, excluding third molars. The data were used to determine w
hich individuals had the worst periodontitis based on CAL at several t
hresholds. Further analysis was carried out to determine which of thes
e subjects would have been identified on the basis of the presence of
deep (greater than or equal to 6 mm) pocketing, or by using one of a b
attery of partial recording subsets. CAL was frequently present in the
absence of deep pocketing. A subset made up of four approximal sites
around each of the 10 index teeth recommended by the WHO for partial r
ecording (two molars in each quadrant and maxillary right and mandibul
ar left central incisors) and a subset comprising maxillary buccal and
mandibular lingual sites (''Pritchard'' sites) performed best of the
subsets considered in identifying the subjects who had been found by f
ull mouth assessment to have at least one or at least two approximal s
ites with CAL at thresholds of 2, 3 or 4 mm. It was concluded that mea
surements of CAL using either of these subsets should reduce problems
of under-recording of the prevalence of periodontitis associated with
the use of PPDs alone or on CAL assessment at other partial recording
subsets.
