Background: The aim of the study was to analyze the type and study design of publications in the Journal of Indian Orthodontic Society (JIOS) and the changes in their trends from 2001 to 2020. Materials and Methods: All the online publications in JIOS were classified as background resource, original articles, and case reports. The original articles were further divided into 7 types based on study design. The annual and overall data were compiled. To evaluate the change in trends, the study period was divided into 2 block years: 2001 to 2010 and 2011 to 2020. The differences in the total number of articles and distribution of articles by type and study design were analyzed using Mann–Whitney and chi-square/Fisher’s exact tests, respectively. Results: Background resource, original articles, and case reports comprised 38.7%, 43.9%, and 17.4% of the total articles (n = 845), respectively. Non-clinical (34.5%) and cross-sectional (32.35%) studies formed the bulk of original articles. There were 17 randomized controlled trials (RCTs) (4.58%) and 5 systematic reviews (1.35%) among the original articles. The total number of publications were higher for years in the second block compared to those in the first (Mdn of 63.5 vs 14.5, P < .001[A]:Author: Please note that as per AMA, the actual value of P should be expressed to two digits, whether or not it is significant. P values cannot be 0 or 1 and should be changed either to <.001 or >.99, respectively.). The differences in the distribution according to type were not statistically significant [ X2(2) = 2.052, P = .35]. A reduction in the share of cohort studies and increase in RCTs were found in the second block (F = 19.174, P = .002). Conclusions: The higher proportion of background resource publications and those with study designs lower in the hierarchy of evidence is a matter of concern. Though slow paced, the increase in the number of RCTs and systematic reviews over the past few years is encouraging[A]:Author: Please provide 4 to 5 keywords specific to this article..
AIMS: To evaluate the proportion and completeness of reporting apriori sample size estimation (SSE) in research articles published in the Journal of Orthodontic Science (JOS) and the Journal of Indian Orthodontic Society (JIOS). MATERIALS AND METHODS: All online research articles published in both journals from 2012 to 2020 were screened. Those reporting apriori SSE were analyzed for the study design and completeness of SSE reporting (outcome parameter and assumptions, Type I error, Power/type II error, one or two-tailed test, the method used, justifications for assumptions, adjustments in sample size, and the target sample size). Chi-square or Fisher exact test was used to analyze the differences between the journals in the proportions of articles reporting these characteristics. RESULTS: Twenty articles (13.2%) in JOS and 24 (8.3%) in JIOS, have reported apriori SSE [χ 2 (1, N = 440) = 2.573, P=0.10]. Non-clinical and quasi-experimental studies formed nearly two-thirds of articles reporting SSE in JOS. Quasi-experimental (34%), randomized controlled trials (28%), and cross-sectional studies (24%) formed the bulk of articles reporting SSE in JIOS. Type II error/power was the most frequently reported characteristic in both (75% and 95.8% in JOS and JIOS, respectively), and the number of tails was the least (5% and 0%, respectively). More articles in JOS than JIOS reported the outcome variable used [65% vs. 12.5%, χ 2 (1, N = 44) = 12.99, P <.001] and provided justifications for the assumptions [70% vs 33.3%, χ 2 (1, N = 44) = 5.86, P = 0.01]. CONCLUSION: The extent and completeness of reporting apriori SSE are suboptimal in these journals and require prompt and stringent curative measures.
Due to limited accessibility and postural issues, placement of open coil spring in lingual technique can be a struggle to the operator. In the present technique, along with the archwire, a ligature wire is passed through the lumen of the niti open coil spring. Both ends of the ligature are wound together tightly thereby compressing the coil spring to a smaller length so that it can be placed in the interbracket span without any active force. Once the archwire is ligated to the lingual brackets, the ligature is cut open to free the coil spring to exert desired force.
We read with interest the article and wish to submit few of our observations in the reader's forum. Q1. There are some discrepancies in the literature review reported in the article. a. According to Padwa et al., 1 occlusal canting can be perceived by 90% of untrained observers if it exceeds 4°, and not 3° as reported by the authors. Further the untrained observers were members of the medical profession and not patients. b. The statement regarding the study by Chu et al. 2 that "asymmetry of the oral commissure measuring < 3 mm and eye canting were not recognized as clinically insignificant" is double negative and implies probably the opposite of what the authors want to convey. c. Referring to the work of Song et al., 3 the authors have stated that "55.3% adults without facial asymmetry exhibit lip canting". We could not locate this datum in the article. On the contrary, their study showed that 54.7% of the non-facial deformity patients had parallel (less than 1° angle) oral commissure and exocanthion lines implying no clinically significant lip canting.
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.
