Tooth fillings and marginal caries

U radu je vršeno kliničko ispitivanje rubnog karijesa na zubima s amalgamskim i silikatnim ispunima starih između jedne i 5 godina. Zubi su bili sanirani u raznim stomatološkim ambulantama grada Zagreba na populaciji stanovništva između 20 i 32 godine života. Ispitivanjem je obuhvaćeno 410 zubi s amalgamslkim ispunima i 314 zubi sa silikatnim ispunima. Nađen je vrlo visoki postotak rubnog karijesa. Više rubnog karijesa je nađeno na granici amalgamskih ispuna (70,49% ) nego na granici silikatnih ispuna (55,73%) (P < 0,005). S obzirom na starost ispuna kod amalgama je porast rubnog karijesa postao statistički značajan kod ispuna stanih tri godine (P < 0,005), a u siliilkatniih ispuna već između prve i druge godine (P < 0,1). Ovaj nailaz se dovodi u vezu s načinom obrade rubova kaviteta, obradom i poliranjem ispuna, kakvoćom materijala, vremenskim normativima za zahvate konzervativne terapije zubi, načinom prehrane i održavanjem oralne higijene stanovništva.A clinical study of marginal caries was caried out in teeth with amalgam and silicate fillings between one and five years old. The teeth had previously been treated at various dental outpatient clinics in Zagreb, in a population aged 20— 32 years. Four hundred and ten teeth with amalgam fillings and 314 teeth with silicate fillings were included in the study. A very high percentage of marginal caries was recorded. The margins of amalgam fillings were found to be more frequently affected by marginal caries than those of silicate fillings(70.49% vs 55.73%; p as early a>s between the first and second year (p < 0.1). This finding was related to the way o f treatment of cavity margins, treatmet and polishing of fillings, quality of the material, time standards of conservative tooth therapy procedures, nutrition and oral hygiene in a population
