Non-surgical periodontal treatment affected salivary TAOC, ALB, UA, SOD and GPX; moreover, these biochemical parameters convincingly reflected periodontal status and tissue response on treatment.

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.

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.

The aim of this study was to evaluate the efficiency of chlorhexidine digluconate solution (CHX) as an adjunct to nonsurgical therapy (NPT) of patients with chronic periodontitis (CP), by analyzing the presence and quantity of periopathogenic microorganisms in subgingival biofilm. DNA was extracted from the subgingival biofilm obtained from 40 patients with CP divided into two groups (NPT+CHX and NPT alone as control) at baseline and 2 months after the therapy. The presence of selected periodontal pathogens (A. actinomycetemcomitans, P. gingivalis, E. corrodens, T. denticola, and T. forsythia) was determined by polymerase chain reaction (PCR), while total bacterial load was assessed by quantitative PCR. The incidence of microorganisms decreased following treatment, both with NPT+CHX and NPT alone, but without reaching statistically significant difference in the NPT group. In the NPT+CHX group, a significant reduction of prevalence of two species: T. denticola (P = 0.008) and T. forsythia (P = 0.016), as well as of total microorganism count (P = 0.002) was observed two months after treatment. In conclusion, the present findings support the use of CHX as adjunctive therapy in CP.
