The relationship between prevalence of dental anxiety and dental caries: cross-sectional study / A relação entre a prevalência da ansiedade de tratamentos odontológicos e cárie dentária: estudo transversal

Objective: This cross-sectional study aimed to assess level of DA among dental students in different grades and patients and to evaluate associations between DA and presence of dental caries. Material and Methods: Both four hundred all-grade dental students of Istanbul University and patients of Istanbul University Hospital were included in the study after random selection. Data regarding gender, oral hygiene habits, frequency of dental visits, and educational level were obtained via questionnaire. DA of participants were measured using both Modified Dental Anxiety Scale (MDAS) and Dental Fear Survey (DFS). The prevalence of caries was determined using International Caries Detection and Assessment System Criteria (ICDAS). Data were analyzed using Kruskal-Wallis, Mann-Whitney U and Chi square tests. Results: Female patients and female 4th-year students had significantly higher MDAS scores (p<0.05). First-year students had significantly higher MDAS and DFS scores than 4th and 5th-year students (p<0.05). Patients who had caries and brushed their teeth less than twice a day had significantly higher MDAS scores (p<0.05). Among 3rd-year students, individuals who visited dentist regularly had lower MDAS scores (p<0.05). Conclusion: DA among senior dental students was lower than that in younger students with an increase in knowledge about dentistry. Tooth brushing frequency and caries prevalence was associated with DA in patient group. No association was found between DA and frequency of dental visits, except in 3rd-year students (AU)

Objetivo: Este estudo transversal teve como objetivo avaliar o nível de DA entre estudantes de odontologia de diferentes anos de graduação, pacientes e associações entre DA e apresença de cárie dentária. Material e Métodos: Quatrocentos estudantes de odontologia de todas os anos da Universidade de Istambul e pacientes do Hospital Universitário de Istambul foram incluídos no estudo após randomização. Dados sobre sexo, hábitos de higiene bucal, frequência de consultas odontológicas e escolaridade foram obtidos por meio de questionário. DA dos participantes foram medidos usando dois questionários: Modified Dental Anxiety Scale (MDAS) e Dental Fear Survey (DFS). A prevalência de cárie foi determinada usando os critérios do Sistema Internacional de Detecção e Avaliação de Cárie (International Caries Detection and Assessment System Criteria - ICDAS). Os dados foram analisados usando os testes Kruskal-Wallis, Mann-Whitney U e Qui quadrado. Resultados: Pacientes do sexo feminino e estudantes também do sexo feminino do 4º ano apresentaram scores de MDAS significativamente maiores (p <0,05). Os alunos do primeiro ano tiveram pontuações MDAS e DFS significativamente mais altas do que os alunos do 4º e 5º ano (p <0,05). Pacientes que tinham cárie e escovavam os dentes menos de duas vezes ao dia apresentaram scores de MDAS significativamente maiores (p <0,05). Entre os alunos do terceiro ano, os indivíduos que visitavam o dentista regularmente apresentaram menores scores de MDAS (p <0,05). Conclusão: A DA entre os alunos do último ano de odontologia foi menor do que entre os alunos mais jovens, devido ao aumento do conhecimento sobre odontologia. A frequência de escovação e a prevalência de cárie foram associadas à DA no grupo de pacientes. Não foi encontrada associação entre DA e frequência de consultas odontológicas, exceto em alunos do 3º ano.(AU)

Effect of dental education on knowledge and clinical behavior of turkish dentists' regarding oral-systemic health of geriatric patientsOral-systemic health of geriatric patients (Running title) / Efeito da educação odontológica no conhecimento e comportamento clínico de dentistas turcos em relação à saúde oral e sistêmica de pacientes geriátricos

Objective: The aim is to evaluate the perspectives of dentists' clinical approaches in terms of their knowledge and education regarding oral-systemic health relation of geriatric patients with a digital survey. Materials and Methods: The demographics, oral-systemic health-related lectures in participants' dentistry education, the level of awareness of the oral-systemic health relationship, and behaviors related to clinical applications were investigated on a digital platform with 49 multiple-choice questions. The results were analyzed with the SPSS 24.0 program. Results: Of a total of 410 dentists (206 women and 204 men), 23% have doctoral and/or specialty titles. While 93.1% of dentists had taken systemic health-related lectures, 21.3% of them rated these courses as "adequate" and 49.3% as weak. 72% of the participants received medical history only at the initial appointment, while 17.9% of them received it at each appointment. Dentists more often associate diabetes and cardiovascular diseases with periodontitis, compared to the development of dental caries. Dentists who think that they should work with physicians in the treatments of geriatric patients with systemic diseases refer more patients to physicians per year (p < 0.001). Conclusions: Dentists have found the lectures on the relationship between oral-systemic health of geriatric patients in dentistry education inadequate. Besides, there is a lack of information on the effects of systemic diseases on caries development, intra-oral findings, and knowledge on treatment approaches. Dentists believe that defining a curriculum that emphasizes interdisciplinary work and organizing scientific activities in partnership with medical associations will play an important role in establishing awareness of oral-systemic health.

Objetivo: O objetivo é avaliar as perspectivas das abordagens clínicas dos dentistas em relação ao seu conhecimento e educação sobre a relação da saúde oral e sistêmica de pacientes geriátricos através de um questionário digital. Material e Métodos: Os dados demográficos, as aulas relacionadas à saúde oral-sistêmica na educação odontológica dos participantes, o nível de conhecimento da relação saúde oral e sistêmica e os comportamentos relacionados às aplicações clínicas foram investigados em uma plataforma digital com 49 questões de múltipla escolha. Os resultados foram analisados com o programa SPSS 24.0. Resultados: De um total de 410 dentistas (206 mulheres e 204 homens), 23% possuem título de doutor e / ou especialidade. Enquanto 93,1% dos dentistas tiveram aulas sobre saúde sistêmica, 21,3% avaliaram esses cursos como "adequados" e 49,3% como fracos. 72% dos participantes recebem histórico médico apenas na consulta inicial, enquanto 17,9% deles recebem em cada consulta. Os dentistas associam mais frequentemente diabetes e doenças cardiovasculares à periodontite, em comparação ao desenvolvimento de cárie dentária. Os dentistas que acham que devem trabalhar em conjunto com médicos no tratamento de pacientes geriátricos com doenças sistêmicas encaminham mais pacientes ao médico por ano (p <0,001). Conclusões: Os cirurgiões-dentistas consideram inadequadas as palestras sobre a relação entre saúde oral e sistêmica de pacientes geriátricos no ensino de odontologia. Além disso, faltam informações sobre os efeitos das doenças sistêmicas no desenvolvimento de cárie, achados intraorais e conhecimento sobre as abordagens de tratamento. Os dentistas acreditam que a definição de um currículo que enfatize o trabalho interdisciplinar e a organização das atividades científicas em parceria com as associações médicas terá um papel importante no estabelecimento da consciência sobre a saúde oral e sistêmica (AU)

Surface hardness evaluation of different composite resin materials: influence of sports and energy drinks immersion after a short-term period

Objectives: This study evaluated the effect of sports and energy drinks on the surface hardness of different composite resin restorative materials over a 1-month period. Material and Methods: A total of 168 specimens: Compoglass F, Filtek Z250, Filtek Supreme, and Premise were prepared using a customized cylindrical metal mould and they were divided into six groups (N=42; n=7 per group). For the control groups, the specimens were stored in distilled water for 24 hours at 37°C and the water was renewed daily. For the experimental groups, the specimens were immersed in 5 mL of one of the following test solutions: Powerade, Gatorade, X-IR, Burn, and Red Bull, for two minutes daily for up to a 1-month test period and all the solutions were refreshed daily. Surface hardness was measured using a Vickers hardness measuring instrument at baseline, after 1-week and 1-month. Data were statistically analyzed using Multivariate repeated measure ANOVA and Bonferroni's multiple comparison tests (α=0.05). Results: Multivariate repeated measures ANOVA revealed that there were statistically significant differences in the hardness of the restorative materials in different immersion times (p<0.001) in different solutions (p<0.001). The effect of different solutions on the surface hardness values of the restorative materials was tested using Bonferroni's multiple comparison tests, and it was observed that specimens stored in distilled water demonstrated statistically significant lower mean surface hardness reductions when compared to the specimens immersed in sports and energy drinks after a 1-month evaluation period (p<0.001). The compomer was the most affected by an acidic environment, whereas the composite resin materials were the least affected materials. Conclusions: The effect of sports and energy drinks on the surface hardness of a restorative material depends on the duration of exposure time, and the composition of the material.
