Alveolar Bone Loss on Abutment and Non-Abutment Teeth in Relation to Removable Partial Denture Wearing. A Six Month Follow Up Study
Gubitak interdentalnog alveolarnoga koÅ”tanog septuma moguÄe je dijagnosticirati na radioloÅ”koj slici u obliku omjera visine interdentalnog alveolarnoga septuma i visine korijenskoga dijela zuba mjerenog od cementno-caklinskoga spojiÅ”ta do vrÅ”ka korijena. Svrha ovog rada bila je izmjeriti visinu interdentalne alveolarne kosti na ortopantomogramima, na zubima nosaÄima i nenosaÄima u pacijenata nositelja djelomiÄnih proteza, prigodom predaje djelomiÄne proteze i nakon 6 mjeseci. Dvadeset pacijenata (5 muÅ”karaca, 15 žena), nositelja djelomiÄnih proteza, sudjelovalo je u istraživanju. Gubitak alveolarne kosti izmjeren je na ortopantomogramima, služeÄi se Shei indeksom, na mezijalnoj i distalnoj stijenci svakoga zuba nosaÄa i nenosaÄa u donjoj Äeljusti, neposredno nakon predaje djelomiÄne proteze te 6 mjeseci poslije. TakoÄer su zabilježene kliniÄke vrijednosti plak indeksa izmjerene na sredini bukalne i palatinalne stijenke te mezio- i disto-palatinalno na svakom zubu nosaÄu i nenosaÄu u donjoj Äeljusti nakon predaje djelomiÄnih proteza te 6 mjeseci poslije. Rezultati istraživanja pokazali su da su se vrijednosti Shei indeksa znatno smanjile na distalnim stijenkama zuba nosaÄima te na mezijalnim i distalnim stijenkama zuba nenosaÄa (p0,05). Gubitak koÅ”tane strukture oko zuba nosaÄa i oko zuba nenosaÄa vjerojatno je viÅ”e povezan s visokim vrijednostima izmjerenoga plak indeksa te s niskom razinom oralne higijene nego s novonastalim optereÄenjem od djelomiÄnih proteza.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 (p0.05). 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
