ApstraktUvod. Kako je gingivitis uvod u periodontitis, sa rezultujućim kobnim Uvod. Kako je gingivitis uvod u periodontitis, sa rezultujućim kobnim Uvod ishodom i gubitkom zuba, on predstavlja veliki socijalni, društveni i medicinski problem. Cilj rada bio je utvrditi prevalenciju gingivitisa kod dece, kao i vezu između gingivalne inflamacije i plak akumulacije. Materijal i metod rada. Klinički pregled gingive, kao i plak detekcija, rađeni su kod dece uzrasta 12-18 god. Za procenu stanja gingive korišćen je gingivalni indeks inflamacije po Cowell-u (GI), dok se za detekciju dentalnog plaka-biofilma koristio plak indeks (PI) po Silness Loeu. Reprezentativni uzorak činilo je 86 ispitanika. Rezultati. Od ukupnog broja pregledanih ispitanika, 28(32,6%) ispitanika bilo je sa zdravom gingivom. U grupi ispitanika sa izmenjenom gingivom -50(58,1%) ispitanika imalo je lakši oblik promena na gingivi; 8 (9,3%/) ispitanika imalo je teži oblik obolele gingive. Svi pregledani ispitanici imali su PI>0. Najviše ispitanika, 47,7%, imalo je PI u rasponu 1-2; 36,0% ispitanika imalo je PI 2-3, a najmanje, tj. 16,3% ispitanika bilo je sa PI 0-1. Zaključak. Analizom statističkih podataka može se zaključiti da je PI direktno proporcionalan GI-u. Srednje vrednosti PI od 1,757 za ispitivanu populaciju poklapaju se sa srednjim vrednostima GI od 1,894, što odgovara nađenom stanju gingive.Ključne reči: gingivitis, dentalni plak-biofilm, etiologija gingivitisa Uvod Inflamatio gingivae -gingivitis je oboljenje gingive multikauzalne etiologije, gde dominantnu ulogu u nastanku bolesti ima infektivna etiologija. Gingivitis je veoma rasprostra-Abstract Introduction. As gingivitis precedes periodontitis with the resultats poor outcome and loss of teeth, it poses a serious social and medical problem. Aim. Our aim was to assess the prevalence of gingivitis in children, and to establish the association of gingival inflammation with accumulation of dental plaque. Methods. Clinical examinations of the gingiva and detection of dental plaque were performed in children aged 12-18 years. The Cowell Index (CI) of gingival inflammation was used to assess the gingival status, while the plaque index (PI) by Silness-Löe was used to detect dental plaque (biofilm). Our representative sample consisted of 86 examinees. Results. Out of the total number of examined children, there were 28 children (32.6%) with healthy gingiva. In the group of those with altered gingiva, 50 children (58.1%) had some milder forms of gingival change; 8 children (9.3%) had more severe gingival changes. All the examined children had their PI>0. Most children (47.7%) had PI in the range 1-2; 36.0% children had PI in the range 2-3, and there were only 16.3% of children with PI 0-1. Conclusion. The analysis of statistical data suggested that PI was directly proportional to GI. The median values of PI of 1.757 for the stud-rectly proportional to GI. The median values of PI of 1.757 for the stud-rectly proportional to GI. The median values of PI of 1.757 for the stud ied population correlated ...
