Impact of oral health conditions on the quality of life of workers

Occupational health has been the scope of numerous studies, primarily due to the concern that the worker should enjoy good working conditions and a satisfactory quality of life. This study seeks to analyze the impact of oral health on the quality of life of workers at a public university using the simplified version of the Oral Health Impact Profile (OHIP-14) and associated factors. A cross-sectional study was conducted with 326 workers who responded the questions of OHIP-14 about self-rated health, oral morbidity, and socioeconomic and demographic questions. Multiple linear regression analysis was performed to verify the association between the independent variables and OHIP-14. About 40% of the impact of oral health on quality of life can be explained by the variables: education level (p = 0,03), age (p = 0,03), reason for visiting a dentist (p = 0,01), oral health perception (p < 0,01) and satisfaction with teeth and mouth (p < 0,01). The use of OHIP-14 can be useful for planning programs and actions focused on health education for occupational health, prioritizing workers with greater psychosocial impacts caused by oral problems.

Position of lingual foramina in cone beam computed tomography and its implications for choosing the dimensions of dental implants for mandibular symphysis

ABSTRACT Objective: To identify the lingual foramina in a Brazilian population of 210 individuals through Cone-Beam Computed Tomography images, in order to guide the installation of dental implants in the region of the mental symphysis. Methods: After identifying the lingual foramina on a parasagittal section, four measurements were taken: distance to the alveolar ridge, distance to the mandibular lower border, distance to the limit of the vestibular cortical, and alveolar ridge inclination angle. The measurements were compared in relation to gender by the Mann-Whitney test. The association between gender and the number of foramina was done by the chi-square test. Pearson’s correlation analyzed the linear relationship between age and number of foramina. Results: Lingual foramina are present in 99.6% of the research participants. In the upper-inferior direction, a mean distance to the alveolar ridge of 21.4 mm was noted, while the mean distance to the lower mandibular border was 13.1 mm. In the bucco-lingual direction, a mean distance from the lingual foramina to the vestibular cortical of 15.2 mm is noted. The inclination angle of the alveolar ridge had a mean of 25.4º. Regarding gender, the test was not significant only for the distance to the vestibular cortical. Conclusion: The lingual foramina had a descending way in 100% of cases, being positioned mainly in the middle thirds (66.5%) and lower thirds (32.7%) of the mandibular ridge height. The use of dental implants up to 13 mm in length and up to 4 mm in diameter in the region of the symphysis mentualis is recommended

Uso de métodos não invasivos para avaliação da espessura muco-gengival: a tecnologia a favor do diagnóstico

O objetivo no presente estudo foi realizar uma revisão atualizada da literatura sobre os diferentes métodos não invasivos utilizados para avaliação da espessura muco-gengival. O biotipo gengival é considerado um dos principais elementos de influência no resultado do tratamento estético. Pacientes com gengiva espessa demonstram ser mais resistentes à recessão gengival após terapia cirúrgica e/ou restauradora. Em contrapartida, pacientes com biotipo fino apresentam maior risco de recessão, sendo necessário, muitas vezes, o enxerto de tecido conjuntivo. O palato é a principal área doadora para enxerto de tecido conjuntivo subepitelial, sendo que a determinação da espessura da mucosa palatina é de grande importância para a previsibilidade dos procedimentos cirúrgicos. Existem diversos métodos para mensurar a espessura muco-gengival, alguns considerados invasivos, como: a avaliação transgengival (ou transmucosa); e outros, mais recentes, considerados não invasivos, como as imagens seccionais de ultrassom, tomografias computadorizadas ou imagens de ressonância magnética. Apesar de diversos estudos demonstrarem resultados positivos do uso de exames por imagens para avaliação da espessura dos tecidos muco-gengivais, concluiu-se que os métodos invasivos ainda parecem ser os mais utilizados

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
