OBJECTIVES: The aim of this study was to correlate the caries-related variables of special needs patients to the incidence of new caries.

MATERIALS AND METHODS: Data for socio-demographic information and dental and general health status were obtained from 110 patients treated under general anesthesia because of their insufficient co-operation. The Cariogram program was used for risk assessment and other caries-related variables were also analyzed. Within a defined follow-up period (16.3 ± 9.5 months), 64 patients received dental examinations to assess newly developed caries.

RESULTS: At baseline, the mean (SD) values of the DMFT (decayed, missing and filled teeth) and DT (decayed teeth) for the total patients were 9.2 (6.5) and 5.8 (5.3), respectively. During the follow-up period, new caries occurred in 48.4% of the patients and the mean value (SD) of the increased DMFT (iDMFT) was 2.1 (4.2). The patients with a higher increment of caries (iDMFT ≥3) showed significantly different caries risk profiles compared to the other patients (iDMFT

CONCLUSIONS: Caries risk assessment could predict the incidence of future caries in hospital-based dentistry. Past caries experience and inadequate oral hygiene maintenance were largely related to caries development in special needs patients.
