A highly cited paper is seen as a landmark in any field and can influence both research and clinical practice. This study aimed to quali-quantitatively analyze the 100 most-cited papers in Cariology. A search strategy was first determined using specific keywords related to the field. A comprehensive search was then conducted in the Thompson Reuters Web of Science citation indexing database up to April 2019. Papers focused on any aspect of Cariology were included. A panel of 4 researchers conducted the selection of papers and extracted data on the number of citations, title, authors, country, year, journals, study design, and topic of interest. Scopus and Google Scholar were also searched to compare the number of citations. The VOSviewer software was used to generate bibliometric networks. The number of citations among the top 100 most-cited papers ranged from 168 to 1,961 with a mean of 292,66. Three papers had more than 1,000 citations. The <i>Journal of Dental Research</i> (20%) and <i>Caries Research</i> (17%) had more top papers. The oldest and the most recent papers were published in 1960 and 2015. Literature reviews (35%) and laboratorial studies (31%) were the most common study designs. The countries with the highest number of most-cited papers were the USA (40%), Sweden (10%), and Japan (9%). The most studied fields of interest were etiology/pathogenesis (41%) and prevention (20%). VOSviewer maps revealed collaborative networks between countries and organizations. The top 100 most-cited papers in Cariology were published mainly by European and Anglo-Saxon American authors and were composed mainly of literature reviews with etiology/pathogenesis as the most frequent topic of interest.
Traumatic dental injuries are highly prevalent among preschool children. When occurring at a very young age (prior to the eruption of the primary teeth), such trauma can disturb the normal development of the permanent dentition and, more rarely, affect the primary dentition. This report describes a case of a patient who suffered dentoalveolar trauma at six months of age that caused rare developmental problems in the primary dentition, such as impaction, dilacerations, hypoplasia, and odontoma. Imaging revealed that alterations also occurred in the permanent dentition. This report demonstrates that dentoalveolar trauma prior to complete development of the dentition and even before the eruption of the primary teeth can lead to highly uncommon abnormalities in the primary dentition. Moreover, there may be repercussions in the permanent dentition when the germs of these teeth are injured by the intraosseous displacement of primary teeth.
The aim of this cross-sectional study was to assess the impact of temporomandibular disorder (TMD) on oral health-related quality of life (OHRQoL) of adolescents. The OHRQoL of adolescents undergoing dental treatment at a University clinic in 2019 was measured using the Brazilian version of the Oral Heath Impact Profile – 14 (OHIP-14). The diagnosis of TMD was performed using Research Diagnostic Criteria for Temporomandibular disorders (RDC/TMD). The patients were examined for other oral conditions and the parents/guardians answered questions addressing socioeconomic/demographic characteristics and the general health of the adolescents. Statistical analysis involves simple and multiple logistic regression models. Ninety male and female adolescents between 13 and 18 years of age participated in the study. The prevalence of negative impact on OHRQoL was 34%. In the unadjusted analysis, negative impact on OHRQoL was associated with a poorer self- perception of general and oral health of the adolescent, nonspecific symptoms including pain, and generalized anxiety disorder, caries, reports of dental pain, muscle disorders and disc displacement, and chronic pain related to TMD. In the adjusted model, negative impact on OHRQoL was associated with all diagnoses related to TMD on the RDC/TMD, except signs of depression. Adolescents with at least one diagnosis related to TMD were 4.13-fold more likely (95% CI:1.08-15.80) to have negative impact on OHRQoL than adolescents without a diagnosis of TMD. The different diagnostic categories of TMD had a negative impact on the OHRQoL of the adolescents analyzed in the present study.
Objective: To assess the association between temporomandibular disorder (TMD) with sociodemographic factors, health-related factors, and oral conditions in adolescents. Material and Methods: This crosssectional study was developed with 89 adolescents between 13 to 18 years. TMD diagnosis was obtained by the Research Diagnostic Criteria for Temporomandibular Disease (RDC/TMD) Axis I. Diagnoses of chronic pain, depression, presence of non-specific physical symptoms, including pain and anxiety, were obtained by the RDC/TMD Axis II. The feeling of happiness was measured by the Subjective Happiness Scale. Socio-economic and demographic characteristics were collected through self-administered questionnaires. Patients were examined for dental caries, dental trauma, malocclusion, and tooth wear. Parents answered a sociodemographic, economic, and general health questionnaire. Data were submitted to descriptive statistics, and a logistic regression model was used to assess the association between TMD and the socio-economic, demographic, health-related, and clinical variables. Results: TMD prevalence was 42%. TMD was associated to skin color (p=0.040), use of medications in the past year (p = 0.020) and previous dental trauma (p=0.030). Also, it tended to be associated with the presence of probable awake bruxism (p=0.053). Conclusion: Sociodemographic factors, health-related factors, and oral conditions play a role in TMD, with nonwhite adolescents, those who had used medications in the past year and/or had previous dental trauma having a greater chance of present this disorder.
Adolescence is marked by changes and vulnerability to the emergence of psychological problems. This study aimed to investigate associations between anxiety/depression/chronic pain and oral health-related quality of life (OHRQoL)/happiness/polymorphisms in the COMT, HTR2A and FKBP5 genes in Brazilian adolescents. A cross-sectional study was conducted with ninety adolescents 13 to 18 years. Anxiety, depression and chronic pain were evaluated using the RDC/TMD. The Oral Health Impact Profile was used to assess oral OHRQoL. The Subjective Happiness Scale was used to assess happiness. Single-nucleotide polymorphisms in COMT (rs165656, rs174675), HTR2A (rs6313, rs4941573) and FKBP5 (rs1360780, rs3800373) were genotyped using the Taqman® method. Bivariate and multivariate logistic regression analyses were performed (p < 0.05). Chronic pain and depression were associated with feelings of happiness (p < 0.05). A significant inverse association was found between anxiety and OHRQoL (p = 0.004). The presence of minor allele C of COMT rs174675 was significantly associated with depression (p = 0.040). Brazilian adolescents with depression and chronic pain considers themselves to be less happy than others and those with anxiety are more likely to have a negative impact on OHRQoL. Moreover, the rs174675 variant allele in the COMT gene was associated with depressive symptoms in Brazilian adolescents.
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.
