The present study demonstrated that cigarette smoking increases the amount of dental plaque over time in smokers and does not influence GCF contents of IL-6 and TNF-alpha.
A very small portion of the renal dialysis population is affected by severe forms of periodontitis requiring complex periodontal treatment. However, all such patients should be given oral hygiene education as a priority.
The aim of this study was to compare the long-term effectiveness of five desensitizing products on 25 male and 27 female patients (total 52) aged 21-67 years (mean 36 +/- 7 years) suffering from cervical dentine sensitivity. All subjects were seen by the same examiner (ID) who was blinded to the applied treatment for 3-month clinical study. Patients were asked to record their overall sensitivity by marking a point on a 10 cm Visual Analogue Scale (VAS). Two hundred and seventy-seven sensitive teeth were treated by one of the five desensitizing products, all of which were placed following manufacturers' instructions by the other investigator (AS). A paired (split mouth) study design was used and selection of quadrants was randomized. At the post-treatment and at 10 days and 3 months periods, sensitivity measurements were recorded by the same investigator (ID). Statistical analysis showed that all of the VAS scores at post-treatment evaluation points were significantly decreased compared with baseline data (P < 0.05). There was a significant reduction in mean sensitivity scores in the Protect Liner F and the Health-Dent Desensitizer groups when compared with Fluoline varnish at the 10-day time point (P < 0.05). At 3 months, the Protect Liner F group continued to show a significantly reduced sensitivity level when compared with Health-Dent Desensitizer, Single Bond, Fluoline and Gluma Desensitizer (P < 0.05). The present study demonstrated that although at the end of 3-month evaluation period all desensitizers showed lower VAS sensitivity values compared with baseline, there were differences in the level of reduction of cervical dentine sensitivity.
Background: Gingival recession (GR) is one of the most common esthetic concerns associated with periodontal tissues. Recently, tissue engineering technology has been developed and applied in periodontology for the treatment of GR. The aim of this study is to compare the clinical efficacy of collagen membrane with or without autologous gingival fibroblasts under a coronally advanced flap for root coverage.Methods: In this split‐mouth, controlled clinical study, 22 sites are selected from 11 patients with Miller Class I recessions affecting canines or premolars in the maxillary arch. One tooth in each patient was randomized to receive either a collagen membrane (CM) (control group) or a collagen membrane seeded with autologous gingival fibroblasts (CM+GF) (test group) under a coronally advanced flap. Thickness of the gingiva, GR, and percentage of root coverage (PRC) were recorded by a calibrated examiner at baseline and 3, 6, and 12 months postoperatively. Furthermore, GR and PRC were evaluated using photogrammetric analysis at baseline and 3, 6, and 12 months.Results: Both treatments resulted in a significant gain in root coverage compared with baseline. A statistically significant increase was detected in PRC in the test group compared with the control group. No significant difference was noted between the test and control sites regarding the thickness of the gingiva.Conclusions: The results indicated that CM+GF prepared by tissue engineering technology can be considered an alternative method for the treatment of Miller Class I recession defects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
