Nocturnal Salivary Fluoride Bioavailability After Brushing with a High-fluoride Dentifrice.

The use of fluoridated dentifrices is recognized as the main reason for the decline of dental caries and its effect is associated with the bioavailability of fluoride (F) in the oral cavity. High-fluoride dentifrice has been indicated for patients at high risk of caries and management of root lesions. This study aimed to evaluate the bioavailability of F in saliva after the use of high-fluoride dentifrice during the nocturnal period. Fifteen healthy adults participated in this is in vivo and crossover study in which the concentration of F in their saliva was determined after brushing with the tested dentifrices: a conventional (1450 ppm F) or with high-fluoride concentration (5000 ppm F). Before brushing, the participants collected the non-stimulated saliva (baseline), immediately after brushing (time zero) and after 5min, 2h, 4h, and 8h, during the nocturnal period (between 10:00 pm and 06:00 am). The salivary F concentration was determined using a specific F ion electrode. Regarding statistical analysis, a paired t-test was used to compare dentifrices with p fixed at 5%. At baseline, there was no significant difference between groups (p>0.001). Immediately after brushing, both dentifrices increased the F salivary concentration, with the highest concentration reached in time zero; however, the use of 5000 ppm F dentifrice maintained the higher F salivary concentration at all times evaluated (p<0.001), remaining higher until 8 h after brushing. Furthermore, this treatment showed higher F bioavailability in relation to time, evaluated by the area under the curve (p<0.001). Thus, it can be concluded that the high-fluoride dentifrice increased the bioavailability of salivary F during the nocturnal period in comparison with conventional dentifrice.

Effect of Mouthwashes on Solubility and Sorption of Restorative Composites.

OBJECTIVE: Composites sorption and solubility can be precursors of several chemical and physical processes, which lead to deleterious effects on the polymer structure. This study evaluated the effect of mouthwashes on solubility and sorption of composite resins. MATERIALS AND METHODS: Forty-two specimens of each evaluated composite (Filtek Bulk Fill Flow, Opallis Flow, Durafill VS, and Filtek Z350) were prepared and randomized into seven groups for each solution (mouth rinses with and without alcohol and distilled water) and stored for seven days. Solubility and sorption tests were performed according to ISO4049. Data were analyzed using 2-way-ANOVA followed by Tukey's test for means comparison (α = 0.05). In addition, paired t-test was performed to analyze the alcohol effect on the studied composite resin properties. RESULTS: Listerine Cool Mint (containing alcohol in its composition) caused the greatest degree of sorption for all composites tested in comparison to other rinses, while for solubility this behavior was observed for Opallis Flow and Durafill VS composite resins (p < 0.05). Regarding the composites, Opallis Flow showed the highest sorption and solubility values in general (p < 0.05). CONCLUSION: Overall, the sorption and solubility of composites were higher in mouthwashes containing alcohol in its composition, with Opallis Flow being the most affected composite resin.

Avaliação do nível de satisfação dos usuários atendidos na clínica integrada do curso de odontologia da Faculdade Novafapi em Teresina (PI) / Assessing the level of satisfaction of users served in integrated clinical course of dentistry college Novafapi Teresina (PI)

A satisfação do usuário deve ser o principal objetivo de todo serviço de saúde. Por meio da avaliação desta, obtêm-se dados a respeito de suas expectativas, detectam-se as possíveis falhas e buscam-se soluções para a melhoria do serviço prestado. Objetivo: avaliar o perfil e o grau de satisfação de 164 usuários adultos em relação ao atendimento odontológico prestado pelas clínicas integradas de odontologia da Faculdade NOVAFAPI. Material e Métodos: trata-se de um estudo descritivo e transversal. A coleta de dados foi realizada por meio de um questionário em que se abordaram aspectos do atendimento clínico e organizacional, aplicado em entrevista direta, na sala de espera das clínicas. Resultados: indicaram um perfil predominantemente feminino 76,22% que estão trabalhando, 81,71% apresentaram renda de 1 a 2 salários mínimos 62,80%.Quanto à satisfação técnica, 89,02% dos usuários receberam orientações sobre procedimentos preventivos, 68,29% não sentiram dor e 60,37% não tiveram medo. A avaliação da receptividade pelo aluno e professor mereceu uma classificação de 62,80% e 48,17%, respectivamente. As sugestões sobre melhorias foram selecionadas com mais atendimentos durante a mesma semana (6,10%) e menor tempo de espera (14,63%). Conclusão: a maioria dos usuários entrevistados mostrou-se muito satisfeita em relação à qualidade do serviço odontológico prestado pela clínica integrada da instituição supracitada.

User satisfaction should be the primary goal of any health service. By evaluating this, data is obtained about user expectations, possible faults can be detected and solutions can be sought to improve the service. Objective: To assess the profile and degree of satisfaction of 164 adult users of dental care provided by integrated dental clinics at NOVAFAPI College. Methodology: This is a descriptive and transversal study. Data was collected using a questionnaire focusing on aspects of organizational and clinical care, which was applied by direct interview in the waiting room of clinics. Results: the profile of users was predominately female (76.22%), in employment (81.71%), with an income of 1 to 2 minimum wages (62.80%). As for technical satisfaction, 89.02% of users received instructions on preventive procedures, 68.29% felt no pain and 60.37% had no fear. The evaluation of receptivity by the student and teacher received a rating of 62.80% and 48.17% respectively. Suggestions on improvements were for more consultations during the same week (6.10%), and a shorter waiting time (14.63%). Conclusion: The majority of users interviewed were very satisfied with the quality of dental services provided by the integrated clinic of the aforementioned institution.

Disfunção craniomandibular: análise de parâmetros para sua identificação / Craniomandibular dysfunction: analysis of parameters for its identification

Avaliaram-se 126 pessoas de ambos os sexos com o objetivo de estabelecer uma correlação desta disfunção a diferentes parâmetros, tais como: abertura de boca, forma de mastigação, habilidade da mão, contenção e presença de prótese dentária. Constatou-se que a DCM manifesta-se silenciosamente e não apresenta significativa relação com estes parâmetros, exceto a contenção dentária.

O uso do dentifrício na remoçäo mecânica da placa bacteriana / The use dentifrice in the mechanical removal of bacterial plaque

Este estudo foi realizado com 100 escolares de ambos os sexos com idade de 10-11 anos, objetivando avaliar (a) a influência do uso do dentifrício na remoçäo mecânica da placa bacteriana pela técnica de Fones e (b) o número de movimentos necessários para a remoçäo da placa bacteriana nas diferentes regiöes da cavidade bucal. Os resultados mostraram que a açäo do dentifrício näo influenciou no número de movimentos necessários para a remoçäo da placa bacteriana. Para cada uma das regiöes estudadas, foram necessários 12 movimentos em média com o uso do dentifrício, enquanto que sem o uso do dentifrício foi necessária uma média de 12 movimentos para os dentes da regiäo posterior direita; 11 movimentos para a regiäo anterior e 13 movimentos para a regiäo posterior esquerda
