Preemptive use of ibuprofen and desensitizer decreases immediate tooth sensitivity after in-office bleaching: A triple-blind, randomized, placebo-controlled clinical trial.

BACKGROUND: The authors evaluated the synergistic analgesic effect of preemptive administration of 400 mg of ibuprofen (IBU) and potassium fluoride 2% (KF2), both in isolation or combination, on the painful perception of tooth sensitivity after tooth bleaching. METHODS: Fifteen patients participated in this triple-blind, randomized, placebo-controlled clinical trial. The study used a crossover design for drug administration and a split-mouth design for desensitizer agent. Four paired groups were formed: IBU plus KF2 (IBU + KF2); IBU (IBU + placebo KF); KF2 (placebo IBU + KF2), and placebo (placebo IBU + placebo KF). The outcome measure was the perception of tooth sensitivity, assessed using a visual analog scale. Data were collected at 4 different times: immediately after tooth bleaching (baseline) and after 6, 30, and 54 hours. Statistical analysis was performed using the Friedman test and relative risk. RESULTS: IBU plus KF2 was found to be more effective in reducing tooth sensitivity immediately after bleaching (baseline) compared with the placebo group (P < .05). The risk of experiencing moderate or severe tooth sensitivity was approximately 4 times higher in the placebo group than in the IBU plus KF2 group (relative risk, 4.00; 95% CI, 1.01 to 15.81; P = .025). CONCLUSIONS: The combined use of 400 mg of IBU and KF2 appears to be beneficial in managing postbleaching tooth sensitivity. It provides a superior analgesic effect compared with placebo. PRACTICAL IMPLICATIONS: The preemptive administration of IBU plus KF2 reduces tooth sensitivity after tooth whitening when compared with placebo. This clinical trial was registered in the Brazilian Clinical Trials Registry Platform. The registration number is U1111-1249-8191.

Avaliação de diferentes protocolos no clareamento dentário / Evaluación de diferentes protocolos en el blanqueamiento dental / Evaluation of different protocols in dental bleaching

Introdução: A estética é a principal busca nos consultórios odontológicos e um dos tratamentos mais realizados é o clareamento dentário, a cada ano mais profissionais buscam a melhor técnica no que diz respeito a longevidade, efetividade, facilidade de passos clínicos e menor desconforto para o paciente Objetivo: Avaliar a influência da modificação do protocolo para aplicação de agentes clareadores utilizados em consultórios odontológicos, determinando a mudança de cor de diferentes agentes clareadores em dentes submetidos a diferentes protocolos. Material e métodos: Uma amostra de 20 dentes selecionados e codificados tiveram suas cores estabelecidas de acordo com a escala Vita Classica. Seccionados e divididos em quatro grupos entre protocolo convencional e modificado e uso dos agentes clareadores Whiteness HP e Whiteness HP Maxx. Resultados: A modificação do protocolo alcança resultados satisfatórios e sem diferença estatisticamente significativa quando comparado ao que é preconizado pelos fabricantes. Conclusões: Os resultados sugerem que a modificação pode representar uma ferramenta útil na prática clínica, uma vez que permite torna-lo mais eficaz, diminuir custos e quantidade de material utilizado(AU)

Introduction: Aesthetics is the main search in dental offices and one of the most accomplished treatments is dental bleaching, each year more professionals seek the best technique regarding longevity, effectiveness, ease of clinical steps and less discomfort for the patient Objective: To evaluate the influence of the modification of the protocol for the application of bleaching agents used in dental practices, determining the color change of different bleaching agents in teeth submitted to different protocols. Material and methods: A sample of 20 selected and coded teeth had their colors established according to the Vita Classica scale. Sectioned and divided into four groups between conventional and modified protocol and use of whitening agents Whiteness HP and Whiteness HP Maxx. Results: Modification of the protocol achieves satisfactory results and without statistically significant difference when compared to what is recommended by the manufacturers. Conclusions: The results suggest that the modification can represent a useful tool in clinical practice, since it allows to makes it more effective, to reduce costs and quantity of material used(AU)
