    Objective: To evaluate the advantages of a novel protocol involving full-mouth erythritol-powder air-polishing followed by ultrasonic calculus removal in the maintenance of patients treated for gingivitis, with a focus on time and comfort. Methods: Systemically healthy patients with gingivitis were selected. Following a split-mouth design, quadrants 1-4 and 2-3 were randomly allocated to receive air-polishing followed by ultrasonic calculus removal following a protocol known as Guided Biofilm Therapy (GBT) or traditional full-mouth ultrasonic debridement followed by polishing with a rubber cup and prophylactic paste (US + P). Bleeding on probing (BoP) and the plaque index (PI) were collected at baseline (T0), 2 weeks (T1), 4 weeks (T2), 3 months (T3), and 6 months (T4) and 12 months (T5). Following the same randomization, prophylactic therapy was provided at 3 months (T3) and 6 months (T4). Clinical parameters, treatment time and patient comfort and satisfaction were evaluated. Results: A total of 41 patients were selected, 39 completed the study. The clinical parameters were clinically satisfactory for both treatments at every time. At 4 months after treatment, GBT maintained significantly lower BoP and PI. GBT protocol required a significantly lower treatment time, especially at T3 and T4, when it saved 24.5% and 25.1% of the time, respectively. Both treatments were rated positively by most patients. However, GBT was perceived as more comfortable, and a higher number of patients preferred it. Conclusion: No significant difference was observed between GBT and conventional ultrasonic debridement and rubber cup polishing in terms of BoP and PI levels. The GBT protocol allowed less time expenditure and higher patients' perceived comfort

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Rating behavioral problems in adolescent eating disorders: Parent-child differences

    No full text
    The primary objective of this study was to investigate the discrepancies among the perception of behavioral problems self-reported by adolescent patients with restrictive eating disorders (REDs) and rated by their mothers and fathers. Forty-eight female adolescents with RED filled in the Youth Self-Report, their mothers and fathers separately completed the Child Behavior Check List. Patients reported lower scores for somatic complaints, thought problems, and rule-breaking behaviors compared to their mothers and fathers. These findings may inform clinical consultation and treatment
