Sažetak
Loss of interdental alveolar bony septum can be determined directly from a radiograph as the relation between the length of the interdental bony crest of the alveolus to the tooth apex and the distance from the cemento-enamel junction of the tooth to the tooth apex. The aim of this study was to measure the height of the interdental alveolar bone around the abutment and non-abutment teeth in removable partial denture wearers (RPD) on dental panoramic radiographs (DPR) over a period of six months. Twenty RPD patients (5 male, 15 female) participated in the study. The alveolar bone loss measurement was performed on DPRs, using Schei index, on each mandibular abutment and nonabutment tooth on its mesial and distal side, after the RPD delivery and six months later. Recordings of plaque index (PlI) were made at the mid-buccal, mid-palatal, mesio- and disto-palatal surfaces of all abutment and non-abutment teeth in the mandible after the RPD delivery and six months later. The results revealed a decrease in Schei index values, on both abutment and non-abutment teeth, which reached a statistically significant level for distal Schei index values of the abutment teeth and mesial and distal Schei index values of the non abutment teeth (p<0.05) in the 6 month period. There was no statistically significant difference in PlI values between the first and the second measurement (p>0.05). We concluded that the decrease in bone support on both abutment and non-abutment teeth was attributed to the high levels of PlI and probable low level of oral hygiene than to the RPD loading.
