Within the inherent limit of the uncertainty about the true value of gingival thickness, the present results demonstrate the differences between the tested methods, as far as accuracy and reproducibility are concerned. Based on the reproducibility, the transgingival probing with the periodontal probe as well as the ultrasound determination, seem to present an adequate choice for every day practice.

Summary Background Social media are one of the most common and easily accessible ways of gaining information about orthodontic treatment. Objective The main objective of this study was to systematically search the literature and determine the various aspects of the interrelationship between social media and orthodontics from the patient’s perspective. Search methods Electronic database searches of published and unpublished literature were performed. The reference lists of all eligible articles were hand-searched for additional studies. Selection criteria Randomized clinical trials (RCTs), prospective, retrospective, and cross-sectional studies were included. Data collection and analysis Study selection, data extraction, and risk of bias assessment were performed individually and in duplicate by the first two authors. Results One RCT, three retrospective, and four cross-sectional studies were deemed as eligible for inclusion in this review. The studies included patient’s statements in social media or results from questionnaires given to patients. The social media reported were with order of frequency: Twitter, YouTube, Facebook, Google+, Pinterest, and Instagram. The feelings the patients expressed seemed to be more positive than negative: enthusiasm, self-esteem and pleasure, excitement about the aesthetic result, excitement after braces removal but also antipathy, annoyances, reduced self-esteem, and impatience for removing mechanisms. In addition, one study referred to bullying through Twitter. Limitations The high amount of heterogeneity precluded a valid interpretation of the results through pooled estimates. Conclusions and implications This systematic review demonstrated that information about orthodontics, how the patient feels, and other psychosocial facets are spread through social media. It is intuitive that research relating to the effects and impact of orthodontic interventions should account not only for the physical impacts of treatment but also to encompass patient-centered outcomes. Registration The protocol of this study was not registered in publicly assessable database. Conflicts of interest None to declare.

The purpose of this study was to examine the reporting quality of randomised controlled trials (RCTs) published in prosthodontic and implantology journals. Thirty issues of nine journals in prosthodontics and implant dentistry were searched for RCTs, covering the years 2005-2012: The Journal of Prosthetic Dentistry, Journal of Oral Rehabilitation, The International Journal of Prosthodontics, The International Journal of Periodontics & Restorative Dentistry, Clinical Oral Implants Research, Clinical Implant Dentistry & Related Research, The International Journal of Oral & Maxillofacial Implants, Implant Dentistry and Journal of Dentistry. The reporting quality was assessed using a modified Consolidated Standards of Reporting Trials (CONSORT) statement checklist. Data were analysed using descriptive statistics followed by univariable and multivariable examination of statistical associations (α = 0·05). A total of 147 RCTs were identified with a mean CONSORT score of 69·4 (s.d. = 9·7). Significant differences were found among journals with the Journal of Oral Rehabilitation achieving the highest score (80·6, s.d. = 5·5) followed by Clinical Oral Implants Research (73·7, s.d. = 8·3). Involvement of a statistician/methodologist was significantly associated with increased CONSORT scores. Overall, the reporting quality of RCTs in major prosthodontic and implantology journals requires improvement. This is of paramount importance considering that optimal reporting of RCTs is an important prerequisite for clinical decision-making.
