Anatomske karakteristike furkacija i korenova viŔekorenih zuba - epidemioloŔka studija
Background/Aim. Knowledge of numerous variations in anatomical features of furcation area is a prerequisite for the achievement of more predictable results in the therapy of multi-rooted teeth with furcation involvement (FI). The aim of the study was to evaluate the morphological characteristics of extracted molars of adult population in Belgrade, Serbia. Methods. In total, 468 extracted first and second molars, both mandibular and maxillary, were measured. The values of root trunk lengths and root lengths, diameter of furcation entrances (FE), distance between the roots and depth of root concavity were analysed. Results. The maxillary first molars had significantly higher root trunk lengths values than the second molars. As for the mandibular molars, FE was smaller than 1 mm. The distance between the roots was more than 2 mm at the third level of measurement. Conclusion. The buccal FE of maxillary molars was the lowest. The root concavity of the second mandibular molars was higher from the lingual aspect.Uvod/Cilj. Poznavanje mnogobrojnih varijacija anatomskih karakteristika furkacija (furkacionih regija) je preduslov za postizanje predvidivih rezultata terapije furkacionih defekata viÅ”ekorenih zuba. Cilj ovog istraživanja je bio procena morfoloÅ”ke karakteristike izvaÄenih zuba adultne populacije u Beogradu. Metode. Merenja su vrÅ”ena na ukupno 468 izvaÄenih prvih i drugih molara i gornje i donje vilice. Analizirane su izmerene vrednosti dužine korenskog stabla i dužine korenova, preÄnik ulaza u furkaciju, odstojanje izmeÄu korenova i dubina korenskog konkaviteta. Rezultati. Prvi gornji molari su imali signifikantno veÄe vrednosti dužine korenskog stabla od drugih gornjih molara. Kod donjih molara, preÄnik ulaska u furkaciju bio je manji od 1 mm. Na treÄem nivou merenja, odstojanje izmeÄu korenova imalo je vrednost veÄu od 2 mm. ZakljuÄak. PreÄnik ulaska u furkaciju sa bukalne strane gornjih molara bio je najmanji. Dubina korenskog konkaviteta drugih donjih molara bila je veÄa sa lingvalne strane
Antioxidative status of saliva before and after non-surgical periodontal treatment
Introduction. Oxidative stress and antioxidants play an important role in the pathogenesis of inflammatory disease, including chronic periodontitis (CP). Saliva contains enzymatic (glutathione peroxidase - GPx, superoxide dismutase - SOD, etc.) and non-enzymatic (albumin - ALB, uric acid - UA, glutathione, etc.) antioxidants. Objective. The aims of this study were to investigate: a) level of SOD, GPx, UA, ALB and total antioxidative status (TAS) of saliva in CP patients before and after non-surgical treatment, and b) correlations between clinical periodontal parameters and levels of salivary antioxidants. Methods. Saliva was collected from 21 CP patients before and after non-surgical treatment. The condition of periodontium was assessed by plaque index, gingival index, bleeding on probing, probing depth and clinical attachment loss. Level of investigated antioxidants (except GPx) and TAS was determined using colorimetric method and commercial kits. GPx activity was determined using UV method and commercial kits. Results. After the treatment significant increase of UA, ALB, Gpx, TAS was detected (p0.05). A significant correlation was observed between GPx and PI (r=0.575, p=0.008), SOD and GI (r=0.525, p=0.017) before therapy, and SOD and bleeding on probing (BP) (r=0.59, p=0.006), TAS and BP (r=0.453, p=0.045) after therapy. Conclusion. These data suggest that levels of salivary antioxidants generally increase after non-surgical periodontal treatment. Correlation between some clinical periodontal parameters and level of salivary antioxidants was found. [Projekat Ministarstva nauke Republike Srbije, br. 41008
