The periodontal condition of 362 proximal abutment tooth areas facing bridge pontics were compared with that of 362 contralateral tooth surfaces which were in contact with the neighbouring teeth. The Plaque Index (Silness & Löe 1964). the Gingival Index (Löe & Silness 1963) and the Margin Index (Silness 1970a) were recorded. Pocket depths were measured according to Glavind and Löe (1967). The pontics seemed to increase the index values (PII., GI), but had apparently little influence on the pocket depths of the proximal abutment tooth surfaces in the case of non‐subgingival retainer margins. Proximal abutment tooth surfaces with subgingival retainer margins showed a marked increase of the index values (PII, GI) and the depth of the pockets seemed to have increased. The increase of the index values should probably be interpreted as being the accumulated effects of the presence of pontics and the subgingival margins. The increase in pocket depth seemed mainly to result from the subgingival retainer margins.
