“…Their response to intracoronal bleaching with sodium perborate with a 6-week follow-up was also compared. The authors found a discoloration mainly at the expense of a reduction in lightness and an increase in the b* component, with a slight improvement in color after bleaching at the expense of an increase in lightness and a reduction in the b* component [ 23 ]. The present study found a slight improvement in color at the expense of an increase in lightness and a reduction in the b* component.…”

Tooth Bleaching of Discolorations Caused by Hydraulic Cements in Regenerative Endodontic Treatment: A 3-Year In Vitro Study

et al. 2022

This study aimed to evaluate the color change caused by hydraulic cements after 3 years in vitro by simulating their use in regenerative endodontic treatment (RET) and to quantify the color change after external bleaching with 40% hydrogen peroxide at 1, 6, and 12 months of follow-up. Fifty teeth were treated simulating RET. Samples were distributed according to the hydraulic cement to be used (n = 10 per group): negative control (no cement), ProRoot-MTA, MM-MTA, TotalFill BC-RRM, or Biodentine. Three years after RET, two sessions of external bleaching with Opalescence Boost were performed. The color was measured in the cervical and incisal halves of the teeth at different time points: baseline, 3 years after performing RET, and after 1, 6, and 12 months after bleaching. The ΔL, Δa, and Δb were determined. A generalized linear model was used to compare color considering group and time. The ΔEab and the ΔE00 were calculated and the acceptability in color change was determined. Three years after RET, a reduction in lightness (negative ΔL values) was found in all groups. These values significantly increased 1 month after bleaching in all groups (p < 0.05) and reversed at 6 months. One month after bleaching, ΔE00 values (color difference tolerance (CIEDE2000)) ranged from very good (>3.6 ≤ 5.4) to excellent (>5.4). One year after bleaching, the color reverted to values similar to those found 3 years after RET. All groups became darker after RET. The color recovered and even improved compared with the baseline measurement after one month of bleaching but did not remain stable over time.

“…Dental disease is a huge issue for the vast majority of people, with teeth discoloration and its associated diseases being the most prevalent dental problem. − Teeth discoloration is mainly caused by stains (e.g., juice, tea), drugs (e.g., tetracycline), and fluorosis, which can compromise human self-appearance and self-confidence. , Especially during a negligent daily dental cleaning, staining agents produced by nonenzymatic browning reactions of sugars and amino acids that remain on the tooth surface or by exogenous pigmented masses are not effectively cleaned. , As a consequence, research on various teeth whitening strategies has attracted the attention of scholars. To obtain a confident smile and avoid oral diseases, the methods frequently used to whiten teeth are classified into physical and chemical methods. , The physical methods include cleaning and polishing, covering with crowns, and abrasive rubbing, while the chemical method is whitening by peroxide .…”

“…The enamel is polished to increase whiteness, but multiple polishings cause a deficiency of hydroxyapatite crystals on the surface of the enamel, which is causes it to be more susceptible to staining. Chemical whitening is the use of reactive oxygen species (ROS) (e.g., 1 O 2 , ·OH, ·O 2 – , and H 2 O 2 ) produced by hydrogen peroxide to degrade the chromogen to a colorless, smaller compound . When hydrogen peroxide is used to whiten teeth, its low molecular weight allows it to penetrate the pulp chamber and periodontal ligament, causing an inflammatory response. , It may damage the pulp, fibroblasts, and periodontal tissue.…”

“Afterglow” Photodynamic Therapy Based on Carbon Dots Embedded Silica Nanoparticles for Nondestructive Teeth Whitening

Teeth staining is a common dental health challenge in many parts of the world. Traditional teeth whitening techniques often lead to enamel damage and soft tissue toxicity due to the use of bioincompatible whitening reagents and continuous strong light irradiation. Herein, an "afterglow" photodynamic therapy (aPDT) for teeth whitening is proposed, which is realized by energy transition pathways of intersystem crossing. The covalent and hydrogen bonds formed by carbon dots embedded in silica nanoparticles (CDs@SiO2) facilitate the passage of energy through intersystem crossing (ISC), thereby extending the half-life of reactive oxygen species (ROS). The degradation efficiency of aPDT on dyes was higher than 95% in all cases. It can thoroughly whiten teeth by eliminating stains deep in the enamel without damaging the enamel structure and causing any tissue toxicity. This study illustrates the superiority of aPDT for dental whitening and the approach to exploring carbon-dots-based nanostructures in the treatment of oral diseases.

“…Desde a sua comercialização, o MTA (Mineral Trioxide Aggregate) apresenta diversas evidências na literatura sobre a sua melhor performance e maior sucesso clínico e radiográfico do que o formocresol em pulpotomias de dentes decíduos devido a sua biocompatibilidade e bioatividade (American Academy of Pediatric Dentistry, 2020; Mestieri et al, 2015). Apesar disso, o MTA apresenta limitações como alteração na coloração do dente, longo tempo para endurecimento, dificuldade de manipulação e maior custo (Yang et al, 2021;Subay et al, 2013;Çelik et al, 2019).…”

Introdução: O processo de pulpotomia convencionalmente é feito com formocresol, porém, devido as suas características mutagênicas, novos materiais obturadores foram desenvolvidos como alternativa. Objetivo: Revisar a literatura de forma integrativa a respeito do material obturador mais adequado para pulpotomia de dentes decíduos. Metodologia: A busca ocorreu nas bases de dados Pubmed e Medline, por meio dos descritores: “child”, “children”, “primary teeth”, “tooth, deciduous”, “primary tooth”, "pulpotomy", "pediatric dentistry", "endodontics", "root canal filling materials", "materials", "material", "biodentine", "mineral trioxide aggregate", "formocresol", "formocresols", "cytotoxicity", "biocompatible materials", "biocompatibility", "radiopacity", "radiographic" e "radiography, dental". Foram incluídos ensaios clínicos, estudos retrospectivos e estudos prospectivos, publicados entre 2016 e 2021, em inglês ou português. Os critérios de exclusão foram teses, dissertações, monografias, cartas ao editor, livros e revisões de literatura. Resultados: A pesquisa resultou em 9 estudos de ambas as bases de dados, com maior prevalência de ensaios clínicos. Conclusão: O material mais recomendado para realização de pulpotomias em dentes decíduos é o Biodentine e Mineral Trioxide Aggregate, devendo a escolha ser feita de acordo com o critério do profissional e caso do paciente. É preciso que seja considerado os custos e colaboração do paciente durante o tratamento.
