AMX was effective only in a few cases and under certain conditions. Therefore, AZM was more effective in its direct anti-inflammatory action. Conclusion AZM is a consistent and effective inhibitor of neutrophil inflammatory mediator mRNA expression. Clinical relevance Given that a single dose of AZM produces higher and more sustained concentrations of this agent in periodontal tissues than AMX when used as a pre-operative prophylactic antibiotic, AZM has greater potential to inhibit inflammatory mediator expression at peri-implant wound sites than AMX.Objectives Pain and trismus are the most common postoperative complications following a surgical removal of the lower third molar. This randomized, double-blind, placebo-controlled clinical trial evaluated the effect of orally administrated magnesium on postoperative pain and trismus after surgical removal of the lower third molars. Materials and methods The study was conducted on 80 participants who were divided into two groups. Each group took different oral forms of magnesium citrate. Participants in both groups had their two lower molars surgically removed. For one randomly selected third molar, participants received either magnesium citrate tablets or lozenges. selleck chemicals llc For the surgical removal of the lower third molar of the opposite side, the participants received either placebo tablets or lozenges. The data were analyzed using the Wilcoxon signed-ranked test, the Mann-Whitney U test, and the Spearman rank-order correlation with the level of significance set at p less then 0.05. This manuscript was written inv under protocol no. NCT03398382.Objectives To evaluate the influence of intraoral scanning on the quality of preparations for all-ceramic single crowns. Material and methods A total of 690 randomly selected and anonymized in vivo single crown preparations were examined. Three hundred twenty-three preparations were directly recorded with an intraoral scanner (group IS). Data from plaster casts digitized by a laboratory scanner (group ID; N = 367) served as control. Comparisons included convergence angle, marginal design, marginal substance reduction, homogeneity of the finish line, and undercuts. Evaluation was performed using fully automated specialized software. Data were analyzed applying Kolmogorov-Smirnov, Mann-Whitney U test, and Fisher's exact test. Level of significance was set at p less then 0.05. Results Convergence angle was above optimum in both groups, but significantly larger for group IS (p less then 0.001). Marginal design was more ideal in group IS concerning the absence of featheredge design (p less then 0.001) and reverse bevel (p = 0.211). Marginal substance reduction was closer to prerequisites for all-ceramic restorations in group IS (p less then 0.001). Finish lines were more homogeneous in group IS regarding the uniformity of their course (p less then 0.001). Undercuts were more frequently found in group ID than in group IS (p less then 0.001). Conclusions Intraoral scanning of prepared teeth has positive impact on the quality of preparations for all-ceramic single crowns regarding marginal substance reduction, marginal design, homogeneity of the finish line, and undercuts. Clinical relevance Accurate preparation design represents a fundamental condition for success of ceramic crowns. Since there is potential for optimization, intraoral scanning might enhance preparation quality providing instant visual feedback.Objective The main objective of the study was to identify the determinants that contribute to the malignant transformation of oral leukoplakia in a group of patients managed in secondary care. A secondary objective was to compare two dysplasia grading systems to determine their utility in assessing the prognosis. Material and methods The cohort consisted of 93 patients diagnosed during the period 2009-2013. The variables recorded and analysed included age and sex, clinical presentation (colour) and severity of oral epith
