Persistent gender disparity in leading dental publications across four decades: An observational study.

OBJECTIVE: This observational study assessed the differences in the gender of the first and last authors in the most cited dental articles over the last four decades. STUDY DESIGN AND SETTING: Articles were obtained through an electronic search of the most cited articles in dentistry by decade (total n = 400 articles). The 100 most cited studies in each decade (1980 - 1989, 1990 - 1999, 2000 - 2009, and 2010 - 2019), with any study design, with results in dentistry were eligible. The gender of the first and last authors was determined using the Genderize database. Comparative evaluation of gender distribution in general and across the four decades was performed with the Chi-Square test, and the contribution of variables on the citation rate of articles was performed using Linear Regression. RESULTS: There were statistical differences between the gender distributions, with a predominance of men in the first (83.8%) and the last (86.8%) positions (p<0.001). Over the decades, there was a tendency for an increase in the proportion of women as the last author (p = 0.002; Chi-Square Trend Test). However, no statistically significant differences were observed between the genders for the first author in the last four decades (p = 0.163; Chi-Square Trend Test), with an increase of women from 6% to 22% across the last four decades. CONCLUSION: The findings indicate that men lead a large percentage of the most cited articles in dentistry and that this trend does not show substantial modifications over the last years. Nonetheless, for the position of last authorship, an increase in women's representativity was observed over the last decades.

The impact of gender on citation rates: An observational study on the most cited dental articles.

OBJECTIVE: This cross-sectional study aims to determine whether the gender of the authors plays a role in the position of authorship within the 100 most cited articles in dentistry. METHODS: An electronic search was performed in October 2022 in the SCOPUS database, considering filters by 'subject area' [dentistry], 'document type' [article], and 'source type' [journal]. The search was performed without restriction on the study design, publication yearor language. Information regarding each article was then extracted. The gender of the first and last author was determined by associating their first names with the probability of the name being male or female, using the Genderize database. Comparative evaluation of gender distribution was performed with the Chi-Square test. RESULTS: Articles ranged from 5214 to 579 citations. Included studies were published between 1964 and 2019, with the majority being from journals with the highest impact factors in the field. There were statistical significance differences between the gender distribution of the first and last authors, with a predominance of man in both authorships positions (all p<0.00). Only 15% and 12.6% the most cited papers in dental research presented a woman as first and last authors, respectively. CONCLUSION: In conclusion, female authors are not as regarded as male authors in prestigious authorship positions in the most cited dental publications, and gender bias can still be considered prominent in the dental research community. CLINICAL RELEVANCE: The findings of the present study indicate that the gender imbalance in citation practices, reported in several areas, also occurs in the field of Dentistry. It is essential that more discussions be raised about gender disparities and about the female presence in the scientific community.

Prevalence and associated factors of self-reported halitosis among institutionalized adolescents: Cross-sectional study.

OBJECTIVE: To assess the prevalence and associated factors of self-reported halitosis in institutionalized adolescents in a city in southern Brazil. METHODS: This cross-sectional study involved male institutionalized adolescents, aged 15-19 years old, at the Socio-Educational Assistance Center in the city of Passo Fundo, Brazil. Data collection was performed by a research team composed of two interviewers, two clinical examiners of oral health and two examiners of salivary flow. A structured questionnaire was applied, which included demographical, socioeconomical, general health behaviour, presence of health problems and oral health self-perception variables. Decayed, Missing, Filled Index was used for the clinical examination. The salivary flow collection was performed using the mechanically stimulated total saliva method, in which only the liquid component was measured. RESULTS: The prevalence of self-reported halitosis in this sample was 51.5% (n = 35). In the final multivariate analysis, halitosis was significantly associated with the non-white racial group (prevalence ratio [RP]:1.703; 95% confidence interval [95%CI]:1.101-2.634), use of crack (RP:1.857; 95%CI:1.270-2.714) and number of decayed teeth (PR: 1.123; 95%CI:1.008-1.252). The use of alcohol and access to dental care in the last 12 months were not significantly associated with self-reported halitosis. CONCLUSION: It was concluded that non-white and crack-user youngsters had a high occurrence of self-reported halitosis. Higher rates of dental caries are also associated with halitosis.

Self-reported halitosis and associated factors among older adults: A cross-sectional study.

Background: Population-based studies assessing the prevalence and associated factors of halitosis among older adults are scarce. Objectives: To evaluate the prevalence of self-reported halitosis and associated factors among older adults. Method: ology: Individuals aged ≥60 years were included. The main outcome was self-reported halitosis. Exposure variables were age, sex, skin color, level of education, marital status, presence of systemic health problems, use of medication, smoking exposure, alcohol exposure, access to dental care, toothbrush frequency, use of dental floss, number of present teeth, use of and need for dental prosthesis. Associations between the outcome and independent variables were performed with Poisson regression models with robust variance (p < 0.05). Results: A total of 569 older adults were included, of which 35.5% (n = 202) self-reported halitosis. In the final multivariate model, higher age (prevalence ratio [PR]:0.967; 95% confidence interval [95%CI]:0.946-0.988) and level of education (PR:0.673; 95%CI:0.469-0.967 and PR:0.635; 95%CI:0.414-0.973 for medium and high level of education, respectively, compared to low level) were associated with halitosis. Conversely, no access to dental care (PR:1.322; 95%CI:1.044-1.676) and a higher number of teeth present (PR:1.023; 95%CI:1.009-1.037) were associated with a higher occurrence of self-reported halitosis. Conclusion: A high prevalence of self-reported halitosis was detected among older adults and was associated with lower age, lower level of education, no access to the dentist and higher number of teeth present.

Systematic reviews on the success of dental implants present low spin of information but may be better reported and interpreted: An overview of systematic reviews with meta-analysis.

OBJECTIVE: To estimate the prevalence of spin and completeness of reporting of systematic reviews with metanalysis (SRMAs) in implant dentistry. STUDY DESIGN AND SETTING: Inclusion criteria were SRMAs of randomized clinical trials of implant dentistry on survival, success, or failure rates in humans, with no language restriction. Three databases were searched from inception to May 2021. Main outcomes were prevalence of spin (primary outcome) and completeness of reporting (secondary outcome) in abstracts and full texts. RESULTS: We identified 2481 SRMAs and 45 unique manuscripts were included. There was a low presence of spin in the abstracts and full text, except for adverse events, in which 51.1% (in the abstract) failed to mention any adverse event for summarized interventions. There was an adequate report of SRMAs in the full text except for prospective register (33.3% not reported). However, there was an incomplete report for most items in the abstract considering PRISMA-A checklist. CONCLUSION: In general, the included SRMAs presented a (a) low prevalence of spin (except for adverse events in the abstract); (b) adequate completeness of reporting in the full text (except for prospective register); and (c) incomplete report for most items in the abstracts.
