Objective: Determine whether social media platforms can influence article impact as measured by citations. Methods: Cross-sectional study that analyzed articles published in the top 10 otolaryngology journals by Eigenfactor score in January 2015. Total accumulated Twitter mentions and citations were recorded in 2021. The main outcomes examined the difference in citations, tweets, article types, and author counts accumulated over a 5-year period for all articles that were either tweeted or nontweeted. Results: A total of 3094 articles were included for analysis. The average article was cited 11.2 ± 13.2 times and tweeted 2.10 ± 4.0 times. Sixty-four percent of the articles had at least one tweet. Over the study period, there was a statistically significant difference in mean number of citations between tweeted articles (12.1 ± 15.0) versus nontweeted articles (9.6 ± 10.5) citations, representing a 26% difference ( P < .001). Review articles had the highest mean citations (19.4 ± 23.4) while editorials had the lowest mean citations (2.8 ± 6.9). Tweets peaked in the year of publication, but citations continued to rise in the subsequent years. Tweeted articles’ peak citation rate change was +1.27 mean citations per year, compared to +0.99 mean citations per year in nontweeted articles. The mean author count in tweeted articles (5.40 ± 3.1) was not significantly different than the mean author count in nontweeted articles (5.19 ± 2.65, P = .0794). Conclusion: These data suggest a moderate correlation between tweets and article citations, but a clear difference in the number of citations in articles tweeted versus those with no tweets. Thus, dissemination of knowledge may be impacted by social medial platforms such as Twitter.

Dental Cast

Dental cast analysis is one of the important thing in orthodontic treatments. One of the dental cast analysis which is usually used is Pont analysis, proposed in 1909. Pont did his research to a population in French which is Caucasian and stated that his theory needs to be tested to another ethnics to verify the applicability of Pont analysis to that population. On each race, there are some specific physical characteristics such as the form and width of dentition and dental arch. Minang population are Mongolian who has the different characteristics of dentition and dental arch with the Caucasians.The aim of this study is to identify whether Pont analysis is precise to be used to Minang population. Method : Cross-sectional design was used in this study. This study was done to 65 upper dental casts from Minang student at the Faculty of Dentistry Andalas University who met the inclusion criteria. The difference between the measured and the calculated interpremolar and intermolar arch width was tested with paired T test with the significant value of 0.05 (p=0.05). Result : Mean value of interpremolar width was 37.8838 ± 2.29042 mm and intermolar width was 47.6046±3.18780 mm. The result of statistical analysis showed that there is no significant differences of the measured and the calculated interpremolar and intermolar width of Minang Student at Faculty of Dentistry Andalas University (p>0.05). Conclusion : Pont analysis can be used as one of the dental cast analysis in orthodontic diagnosis and treatment planning to Minang population. It is suggested to do a further research to identify lower dental arch form of the Minang population whose upper dental arch width equals to the predicted arch width according to Pont’s formula.
