Micro-CT evaluation of maxillary first molars: interorifice distances and internal anatomy of the mesiobuccal root

xlomafota13 shared this article with you from Inoreader Micro-CT evaluation of maxillary first molars: interorifice distances and internal anatomy of the mesiobuccal root Via Brazilian Oral Research Abstract: This study aimed to describe the morphometric relationship of root canal orifices on the pulp floor in the presence/absence of mesiobuccal second canal (MB2) in the maxillary first molars and other aspects of its internal anatomy. Sixty-two maxillary first molars were scanned by micro-CT. The presence of the MB2 canal was verified. The distance between the center points of the MB1, MB2, distobuccal (DB), and palatal (P) canal orifices on the pulp floor were measured (MB1-MB2, MB1-DB, MB2-DB, MB1-P, and DB-P). The MB1-P to DB-P ratio was calculated. The distances between the anatomic apex and the MB1 and MB2 apical foramina were measured. The length of the band-shaped isthmus was also measured. Student's t-test was applied to verify the association between the presence of an MB2 canal, the interorifice distances, and the ratio of the MB1-P to DB-P distance (α = 5%). The MB2 canal was present in 43 roots (69.35%). Statistics showed significant differences when MB2 was present for the largest MB1-P distance (p < 0.05) and higher values for the MB1-P to DB-P ratio (p < 0.05). A band-shaped isthmus was detected in 25.8% of MB roots. The mean distance from the apical foramen to the isthmus floor ranged from 1.74 for MB1 canals to 1.42 for MB2 canals. Canal orifice distances on the pulp floor may predict the presence of MB2 canals. There was a high incidence of isthmus, accessory canals, and apical delta in the critical apical zone in MB roots of maxillary first molars. View on the web Inoreader.

Narratives about a stigma: attributing meaning to the early loss of deciduous teeth on children's caregivers

xlomafota13 shared this article with you from Inoreader Narratives about a stigma: attributing meaning to the early loss of deciduous teeth on children's caregivers Via Brazilian Oral Research Abstract: Qualitative approach about the implications that occur succeeding the premature loss teeth is still insufficient. This study aimed to understand the experience of early loss of deciduous teeth in children's lives, from the perspective of their caregivers. Qualitative case study included 52 caregivers of children from an outpatient service of a public university in the south of Brazil. Early loss of deciduous teeth to trauma or caries was identified through analysis of health records, and afterwards, semi-structured interviews were performed. Textual material was interpreted through the content analysis proposed by Bardin, supported by the ATLAS.ti software. The theoretical perspective of stigma was guided according to the principles of the phenomenology of Maurice Merleau-Ponty, centred on the experience of early loss of deciduous teeth as a historic–cultural expression of a social group. According to caregivers, premature loss of deciduous teeth due to trauma or de cay brings functional limitations with chewing and speaking, and impairments related to social interaction with other children. The repercussions of missing teeth were not limited to the child's image, but also brought changes in families' daily lives. However, when early tooth loss was due to extraction because of pain and suffering, caregivers perceived the loss as 'commonplace' in children's lives. The understanding of how children see themselves without teeth in their social world for their caregivers, which also includes their family and friends, determines how much experiencing tooth loss affects their lives. Besides, caregivers' perceptions related to early loss of deciduous teeth should be included in strategies of oral health promotion programs. View on the web Inoreader.

Radiographic evaluation of dental anomalies in patients with congenital Zika virus syndrome

xlomafota13 shared this article with you from Inoreader Radiographic evaluation of dental anomalies in patients with congenital Zika virus syndrome Via Brazilian Oral Research Abstract: Numerous studies have reported abnormalities in the development of oral structures in congenital infections that also involve microcephaly. In this context, it is necessary to identify possible dental anomalies of shape and/or number in patients with Zika virus syndrome using radiography. The study population consisted of 35 children born with congenital ZIKV who underwent intraoral radiographic examinations for 24 consecutive months. A modified periapical technique was performed in an occlusal position for the maxilla and mandible. Categorical data were expressed as absolute and percentage frequencies and compared using Pearson's Chi-square test, with a 95% confidence interval. Of the entire sample, eight children (22.8%) had dental anomalies of shape and/or number, and four children (11.4%) presented with both anomalies, with agenesis of the upper and lower deciduous/permanent incisors and dental form modifications, such as microdontia and anomalous cusps. When we c onsidered age and sex, there was no statistically significant difference between patients who presented with agenesis and those who presented with modifications. Children with congenital Zika virus syndrome were more likely to have dental modifications in the number and shape of their teeth, and it is essential to implement medium- to long-term monitoring to diagnose other possible alterations throughout the development of the mixed and permanent dentition, favoring their treatment.

Diagnosis of mucosal changes and hospitalized oral cancer patients in Brazil: influence of socioeconomic factors

xlomafota13 shared this article with you from Inoreader Diagnosis of mucosal changes and hospitalized oral cancer patients in Brazil: influence of socioeconomic factors Via Brazilian Oral Research Abstract This study aimed to analyze the influence of socioeconomic factors on the frequency of diagnoses of oral mucosal changes and the number of hospitalized patients with oral and oropharyngeal cancer in Brazil. This cross-sectional study analyzed data from all Brazilian cities in the period 2011–2017. The frequency of diagnoses of oral mucosal changes and the number of hospitalized patients of oral and oropharyngeal cancer in Brazil were extracted from the Primary Care Information System (SIAB) and Brazilian National Cancer Institute (INCA) databases. The socioeconomic factors evaluated were the Gini coefficient of inequality, municipal Human Development Index (MHDI), inadequate basic sanitation rate, employment rate, illiteracy rate and expected years of schooling. Associated factors were examined using bivariate Spearman's correlations and multivariate Poisson regressions, and statistically significant (p < 0.05) correlations between study variables and regression coefficients were obtained. A higher frequency of diagnoses of mucosal changes was observed in cities with a higher Gini coefficient (B = 11.614; p < 0.001), higher MHDI (B = 11.298; p < 0.001), and higher number of hospitalized patients with oral and oropharyngeal cancer (B = 0.001, p < 0.002). Cities with higher Gini coefficients (B = 8.159, p < 0.001), higher inadequate basic sanitation rates (B = 0.09, p = 0.001), lower expected years of schooling (B = -0.718, p < 0.001), and higher illiteracy rates (B = 0.191, p < 0.001) had a higher frequency of hospitalized patients with oral and oropharyngeal cancer. In conclusion, more developed cities showed a higher frequency of diagnoses of mucosal changes. Greater inequality and worse socioeconomic conditions are associated with a higher frequency of hospitalized patients with oral and oropharyngeal cancer in Brazil. View on the web Inoreader.

Sedentary behavior, unhealthy food consumption and dental caries in 12-year-old schoolchildren: a population-based study

xlomafota13 shared this article with you from Inoreader Sedentary behavior, unhealthy food consumption and dental caries in 12-year-old schoolchildren: a population-based study Via Brazilian Oral Research Abstract: This study analyzed the association between sedentary behavior (SB), unhealthy food consumption, and dental caries amongst 12-year-old schoolchildren. An epidemiological survey was carried out in the five largest cities (> 80,000 inhabitants) of the State of Mato Grosso do Sul, Brazil. Data were collected on decayed, missing and filled teeth index (DMFT), sociodemographic characteristics, SB, unhealthy food consumption, and water fluoridation status. The analysis was based on the theoretical framework established by J Sisson. Structural equation models were performed to test the association of dental caries experience with sociodemographic, contextual, and behavioral factors. The mean DMFT index in the five cities was 1.02 (95%CI: 0.39–1.66). Higher sedentary behavior (more than 2 hours/day) [standardized coefficient (SC) = 0.21 95%CI: 0.07–0.39] and higher unhealthy food consumption (more than 4 times/week) [SC = 0.23 (0.10–0.45)] were associated with higher DMFT index than their counterparts. Also, cities with fluoridated water were associated with lower DMFT index [SC = −0.85 (-1.20–-0.50)]. Families who had a per capita income above the poverty line had a direct association with unhealthy food consumption [SC = −0.24 (-0.38–-0.11)]. Unhealthy food consumption mediated the association of sedentary behavior on DMFT index [SC=0.07 (0.02–0.13)]. Sensitivity analysis confirmed the findings. Sedentary behavior mediated by unhealthy food consumption had a significant association with dental caries experience. Public policies must address transdisciplinary actions to reduce sedentary behavior and unhealthy food consumption and promote water fluoridation. View on the web Inoreader.

Impact of adopting different socioeconomic indicators in older adults’ oral health research

xlomafota13 shared this article with you from Inoreader Impact of adopting different socioeconomic indicators in older adults’ oral health research Via Brazilian Oral Research Abstract: This study aimed to evaluate the influence of choosing different socioeconomic status indicators in research regarding older adults' oral health. This is a cross-sectional study that analyzed baseline data from the Brazilian Longitudinal Study on Aging (ELSI-Brazil). The outcomes were edentulism (n = 9,073) and self-reported oral health (n = 9,365). The following socioeconomic indicators were assessed: individual income, per capita household income, and wealth index. Poisson regression analysis with robust variance was performed to estimate prevalence ratios (PR), with their respective 95% confidence intervals (CI), after adjusting for socioeconomic and oral health behavior variables. Absolute inequality measures were also estimated. The individual income indicator was not statistically associated with the results after adjustments. When using per capita household income indicator, individuals in the richest quintile showed a 12% lower prevalence of poor self-report ed oral health [PR: 0.88 (CI: 0.78–0.98)], relative to the poorest, and there was no association with edentulism. When the wealth index was chosen, there was a 22% lower prevalence of edentulism [PR: 0.78 (CI: 0.64–0.94)] and 15% lower prevalence of self-reported poor oral health [PR: 0.85 (CI: 0.78–0.93)] in individuals of the richest quintile, both relative to the poorest quintile. Regarding absolute inequality measures, for edentulism, the wealth index showed the highest absolute inequality. When considering self-reported oral health, per capita household income showed the greatest absolute inequality. Despite scientific challenges and the difficulty of socioeconomic indicator metrics, further investments in its development are critical to measure, promote, and improve population oral health.

Efficacy of 1.23% acidulated phosphate fluoride gel on non-cavitated enamel lesions: a randomized clinical trial

xlomafota13 shared this article with you from Inoreader Efficacy of 1.23% acidulated phosphate fluoride gel on non-cavitated enamel lesions: a randomized clinical trial Via Brazilian Oral Research Abstract: A randomized controlled parallel clinical trial was conducted to evaluate the efficacy of the association of 1.23% topical professional acidulated phosphate fluoride (APF) gel with oral hygiene and dietary instructions on the arrest of active non-cavitated lesions in permanent, mixed, and temporary dentition in children between 3 and 12 years of age. Ninety-eight caries-active children were randomly divided into two groups: a fluoride gel group (n = 49) and a non-fluoridated gel group (n = 49). Each group received up to eight weekly applications of gel, weekly professional toothbrushing with oral hygiene instructions and dietary counselling. Caries lesions were assessed qualitatively through visual-tactile criteria performed in three stages: initial, intermediate, and final. Regression models were applied to identify risk indicators for caries control. Between-group comparison regarding the time taken to arrest the lesions was performed using Chi-squared and Fisher's exact tests. Seventeen children did not receive the allocated intervention, and one was lost to follow-up (n = 80). There was no difference between the control and placebo groups regarding the time to the arrest of the lesion (p >.05). The treatments showed similar results without significant statistical difference (p = 0.33; 95%CI: 0.32–1.48). No adverse effects were observed. It can be concluded that no additional effect of the association of 1.23% APF gel with oral hygiene using fluoride dentifrice and dietary instructions on the arrest of active non-cavitated lesions could be established. We can also confirm the importance of toothbrushing frequency and, consequently, the visible plaque reduction in the control of caries activity. RBR-37V5S3 View on the web Inoreader.

Evaluation of the quality of referral letters: experience of a Brazilian oral medicine service

xlomafota13 shared this article with you from Inoreader Evaluation of the quality of referral letters: experience of a Brazilian oral medicine service Via Brazilian Oral Research Abstract: Optimizing the quality of referral letters could be the first step to a correct clinical approach for patients. Referral letters should be legible and contain the necessary information to avoid delaying the patient's diagnosis and treatment. However, to date, few studies have been conducted on how referrals are performed in Brazil. Knowledge regarding the quality of referral letters can provide information to better guide health care professionals. This study was aimed at analyzing all referrals received by a single oral medicine service in Brazil. Referral letters were classified into poor, regular, good, and excellent based on key items concerning the primary morphology of the lesion, location, diagnostic hypothesis, symptomatology, time of evolution, consistency, size, and limits. A total of 500 referral letters were evaluated, including 271 (54.2%) from a private service and 229 (45.8%) from a public service. Dentists and physicians had written 475 (95%) and 25 (5 %) referral letters, respectively. Among the 500 referrals analyzed in this study, the number of regular, poor, good, and excellent referrals was 236 (47.2%), 203 (40.6%), 58 (11.6%), and one (0.6%), respectively, showing a lack of important clinical information in referrals.

Influence of skeletal class and facial type on nose dimensions in a Brazilian subpopulation: a CBCT study

xlomafota13 shared this article with you from Inoreader Influence of skeletal class and facial type on nose dimensions in a Brazilian subpopulation: a CBCT study Via Brazilian Oral Research Abstract: Evaluating factors that may influence the nose dimensions and, therefore, contribute to the singularity of a person, is important for obtaining a precise facial reconstruction (FR) in forensic anthropology. Thus, the aim in this study was to evaluate the influence of sex, skeletal class, and facial type on nose dimensions of Brazilian individuals using cone-beam computed tomography (CBCT) scans. CBCT images of 54 males and 67 females were classified according to skeletal class (class I, II, or III) and facial type (brachycephalic, dolichocephalic and mesocephalic). Linear and angular measurements of the nose were performed using the CS 3D Imaging software. The measurements obtained for males and females were compared by one-way ANOVA. Two-way ANOVA was used to compare the measurements in the different skeletal classes and facial types. Significance level was set at 5%. All linear measurements were greater in males (p < 0.05); the angular measurements, however, did not differ between sexes (p > 0.05). Linear and angular measurements of class III males were significantly different from the other classes; the same was observed for the angular measurements in females (p < 0.05). Regarding facial types, some linear measurements were significantly greater in dolichocephalics males (p < 0.05). For females, there was no influence of facial type (p > 0.05), except for the nasal convexity angle. Nose dimensions differed in specific points among different skeletal classes and facial types, and there was sexual dimorphism in all linear nose dimensions. This information may be applicable for nose reconstructions, allowing more reliable FR. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

COVID-19 and patients with cancer: Experiment of a French comprehensive cancer center

xlomafota13 shared this article with you from Inoreader COVID-19 and patients with cancer: Experiment of a French comprehensive cancer center Via Association française pour l'étude du cancer Bull Cancer. 2021 Apr 8:S0007-4551(21)00132-6. doi: 10.1016/j.bulcan.2021.02.008. Online ahead of print. ABSTRACT The emergence of the Coronavirus Disease 2019 (COVID-19) has caused profound upset in health systems around the world. As cancer patients seem to be at greater risk, the organization of oncological care had to be adapted. We first report the progress of the "first wave" of COVID-19 at the Institut Curie, a French comprehensive cancer center, by describing the measures implemented to limit the risk of transmission of COVID-19 while ensuring as much as possible the continuation of anticancer treatments. Then, we present the results of a prospective institutional database in which the characteristics and outcome of our patients with cancer and suffering from COVID-19 were collected. From March 13 to April 25, 2020, 141 patients followed at Institut Curie for cancer developed COVID-19, of which 26 (18%) died from it. The minimu m incidence of COVID-19 in Institut Curie is estimated at 1.4% over this period. No risk factors for developing a severe form of COVID-19 related to cancer have been identified. Cancer patients do not appear to be at greater risk of developing COVID-19, nor of having a more severe form than the general population. With the current increase of COVID-19 cases, it seems essential to share the experience already acquired to minimize the impact of this crisis on the long-term outcome of patients followed for cancer.

Richter Syndrome: Diagnostic and Therapeutic Management

xlomafota13 shared this article with you from Inoreader Richter Syndrome: Diagnostic and Therapeutic Management Via Association française pour l'étude du cancer Bull Cancer. 2021 Apr 22:S0007-4551(21)00120-X. doi: 10.1016/j.bulcan.2021.01.014. Online ahead of print. ABSTRACT Richter syndrome (RS) is defined as the occurrence of an aggressive lymphoma, most commonly diffuse large B-cell lymphoma (DLBCL) and rarely Hodgkin lymphoma (HL), in a patient with prior or concomitant chronic lymphocytic leukemia (CLL). RS is estimated to occur in 0.5-1 % per year and is associated with adverse outcome. In the vast majority of patients (80 %), RS is clonally related to the prior CLL. Those with unrelated RS appear to have better outcome. The therapeutic approach is based on those of de novo DLBCL or HL. However, even with modern immunochemotherapy regimens, response rate remains low. In eligible patients with related RS, a consolidation by autologous or allogeneic stem-cell transplantation must be proposed. Combinations including therapies targeting BCR or BCL2 and effective in CLL are currently being ev aluated in RS. Novels immunotherapies could be promising approaches based on preliminary results.
