Cervical wear and occlusal wear from a periodontal perspective

P>The aim of this study was to investigate whether cervical wear was associated with occlusal wear and clinical periodontal parameters in relatively older adults. A total of 30 patients, with multiple non-carious cervical lesions (NCCLs) and without a disease or condition that could cause heavy tooth wear, were included in the study. The periodontal parameters including plaque index, probing pocket depth, gingival recession (GR) and tooth mobility were obtained from 641 teeth of which 475 (74 center dot 1%) displayed NCCLs. The levels of cervical wear and occlusal wear were determined according to a tooth wear index. Premolars were more likely to develop cervical wear than canines, molars and incisors. Cervical wear was significantly associated with less plaque accumulation and the presence of shallow pockets. The teeth with advanced GR and without increased mobility were 2 center dot 583 and 1 center dot 715 times more likely to develop deeper cervical lesions, respectively. Age and the level of occlusal wear were not linked to the bucco-lingual depth of cervical wear. In conclusion, the significant association of advanced cervical wear with the relatively healthy periodontal status suggested the role of abrasion and its possible combined action with erosion in the aetiology of NCCLs. The rate of GR and the lack of tooth mobility could constitute predisposing factors for the progression of cervical wear because the exposed root surfaces could be more susceptible to abrasion and/or erosion, and the non-mobile teeth resisting strongly against frictional forces, thus abrasive effects, could possibly develop cervical wear

Endodontik-periodontal kombine kemik içi defektlerin tedavisinde trombositten zengin fibrin membran ile otojen kemik greftinin kombine kullanımı: olgu sunumu

<p>Platelet-rich fibrin (PRF) is a new generation product of blood sourced material. Its major advantages are ease of preparation, and that blood contents are not changed by biochemical processing which reinforce the product’s autogenous nature. In our study, a 51 years-old male patient attending to our clinic with endodontic- periodontal intraosseous defect was treated with PRF membrane combined with autogenous bone graft in addition to endodontic treatment demonstrated successful results in hard and soft tissue healing.</p> <p><strong> </strong></p> <p><strong>ÖZET</strong></p> <p>Trombositten zengin fibrin (TZF), kan kaynaklı maddelerin yeni jenerasyon ürünüdür.

Clinical Evaluation of Autologous Platelet-Rich Fibrin in the Treatment of Multiple Adjacent Gingival Recession Defects: A 12-Month Study

Leukocyte- and platelet-rich fibrin (L-PRF) belongs to a new generation of platelet concentrates. There are limited numbers of studies focused on the use of L-PRF in gingival recession defects. This study evaluated the safety and effectiveness of using L-PRF membranes as a substitute for free connective tissue grafts (CTGs) as a treatment method for gingival recession defects. A total of 44 Miller Class I/II gingival recessions that were bilateral, adjacent, and greater than 3 mm in size were selected. Each recession site was randomly assigned to the test group (L-PRF) or the control group (CTG). After 12 months, root coverage was 76.63% and 77.36% in the L-PRF and CTG groups, respectively. It is suggested that L-PRF membrane may be an alternative graft material for treating multiple adjacent recessions greater than 3 mm in size without a requirement for additional surgery

The Comparative Evaluation of the Antimicrobial Effect of Propolis with Chlorhexidine against Oral Pathogens: An In Vitro Study

This study aimed to compare the antimicrobial effectiveness of ethanolic extract of propolis (EEP) to chlorhexidine gluconate (CHX) on planktonic Streptococcus mutans, Streptococcus sobrinus, Lactobacillus acidophilus, Lactobacillus salivarius subsp. salivarius, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, Staphylococcus aureus, Enterococcus faecalis, Actinomyces israelii, Candida albicans, and their single-species biofilms by agar dilution and broth microdilution test methods. Both agents inhibited the growth of all planktonic species. On the other hand, CHX exhibited lower minimum bactericidal concentrations than EEP against biofilms of A. actinomycetemcomitans, S. aureus, and E. faecalis whereas EEP yielded a better result against Lactobacilli and P. intermedia. The bactericidal and fungicidal concentrations of both agents were found to be equal against biofilms of Streptecocci, P. gingivalis, A. israelii, and C. albicans. The results of this study revealed that propolis was more effective in inhibiting Gram-positive bacteria than the Gram-negative bacteria in their planktonic state and it was suggested that EEP could be as effective as CHX on oral microorganisms in their biofilm state
