Cross‐sectional study of patients treated, with removable partial dentures with special reference to the caries situation

Abstract

Bergman B, Ericson G: Cross-sectional study of padents treated with removable partial dentures with special reference to the caries situation. Scand J Dent Res 1986; 94: 436-42.Abstract -Thirty-four padents provided with removable partial dentures (RPDs) were reexamined after 3 yr. Garies that had developed during the period were analyzed with regard to the following potential caries risk factors: Lactobacilli, Streptococcus mutans, flow rate and buffer pH of paraffin stimulated saliva, oral hygiene and daily sucrose intake. Of 436 initially intact surfaces 31 (7.1%) had decayed and/or were restored during the 3-yr period. Caries recurred in 26 (6.2%) out of 422 initially restored surfaces during the same period. The development of new or recurrent caries had no correlation to whether or not the surfaces affected were in contact with the RPDs. No single caries risk factor seemed to he sufficiently closely correlated to the number of caries lesions developed to be used alone in the selection of patients at risk. When the sum of assumed negative factors was used a correlation was found for the group as a whole hetween the number of negative factors and the development of caries. However predicting the development of caries in any individual case seems to be more complicated.

Cross‐sectional study of patients fitted with fixed partial dentures with special reference to the caries situation

“…This finding corroborates the observations made by RUNDEGREN & ERICSON (7) atid BERGMAN & ERIGSON (24), who concluded that a combinatioti of several tests for estjtnation of caries activity improved the possibility of individual prediction when selecting risk patients. However, there is always uncertainty about the reliability of patients' dietary histories.…”

Salivary characteristics and dental caries

“…The results of studies in which investigators reported on this association are inconsistent, 23,24,25,26,27,28 and most studies in which investigators found a positive association between low stimulated salivary flow rate and dental caries were conducted in children with syndromes such as cleft lip or palate or in hospitalized older adults. 29 Our study results show that a low resting salivary pH was not associated with higher caries experience in the three age groups.…”

The oral status of elderly removable partial denture wearers

“…Studies have shown that partial dentures in the mouth increase plaque formation, (Bates & Addy, 1978;Bergman, 1987;Kratochvil, Davidson & Guijt, 1982;Schwalm, Smith & Erickson, 1977;Brill et al, 1977) particularly on tooth surfaces in contact with the partial denture (El Ghamrawy, 1976). An increase in caries has been reported in partial denture wearers (Carlsson, Hedegard & Koivumaa, 1965) and in a study by Bergman and Ericson (1986), 64-5% of the incidence of new caries and 88-5% of recurrent caries occurred on abutment teeth. There are studies, however, that do not support the hypothesis that removable partial dentures increase the likelihood of caries development (Bergman, Hugoson & Olsson, 1977).…”
