“…The presented results on dye penetration and particularly the analysis of the T-points comply with a previous in vitro study investigating the marginal integrity between endodontic temporary restorative materials and composite build-ups or bovine dentine (Kameyama et al, 2020). In the present study, the T-point analysis revealed penetration mainly between cervical dentine and preendodontic composite restorations and not between preendodontic composite class-II-restorations and postendodontic composite class-I-restorations when a self-etch adhesive was used.…”

Aim The aim of the study was to investigate the influence of cavity cleaning and conditioning on marginal integrity of directly placed post‐endodontic composite class‐I‐restorations in vitro. Methodology A total of 168 fully intact teeth without caries or fillings received pre‐endodontic composite restorations (class‐II) after their extraction. Occlusal endodontic access‐cavities were prepared, and root canals were instrumented and filled with gutta‐percha and an epoxy resin‐based sealer. Prior to post‐endodontic class‐I‐restoration, access cavities were completely contaminated with sealer, cleaned with alcohol and pre‐treated as follows: cleaner only (alcohol), glycine‐polishing, Al2O3 sandblasting, carbide bur (immediate as well as delayed restoration). A positive control (not contaminated with sealer and adhesive used) and negative control (cleaner used but no adhesive) were established. Half of the teeth from each group were subjected to thermocycling and mechanical loading (TCML). Marginal integrity of post‐endodontic restoration was evaluated in oro‐vestibular or mesio‐distal sections after AgNO3 dye penetration (DP) by standardized photomacroscopic imaging and expressed in per cent of margin length along all segments and separately for enamel, dentine and composite, respectively. Results were analysed non‐parametrically (α = .05). Results No restorations or teeth fractured or debonded completely. Without TCML, the median DP of all segments was significantly higher for the negative control compared with all other groups in oro‐vestibular cutting direction (53%; p = .002) and in mesio‐distal cutting direction (51%; p ≤ .041). The other groups without TCML revealed 16%–24% DP (oro‐vestibular) and 12%–24% DP (mesio‐distal). With TCML, the median DP in oro‐vestibular cutting direction for all segments ranged between 48% and 62% for all groups, a significant difference was only observed between glycine‐polishing and carbide bur (p = .041). In mesio‐distal cutting direction, the median DP in negative control was 69% with TCML and significantly higher compared with all other groups (p = .002). For all other groups, the median DP of all segments ranged between 28% and 40% with TCML without significant differences. Error rates method (k = 7) revealed a significant influence of TCML in general on penetration of all segments in both oro‐vestibular and mesio‐distal cutting directions. Conclusion Additional access cavity pre‐treatment after alcohol cleaning did not improve the marginal integrity of post‐endodontic composite restorations. Thorough cleaning of the access cavity with alcohol seems to assure an acceptable marginal integrity to the tooth and restorative composite.

“…An excellent temporary restorative material must prevent the root canal system from being contaminated by saliva, fluids and microorganisms 16 . The composite resin and glass ionomer cement adhere to the tooth structure, preventing the infiltration of oral fluids at the cement-tooth interface 17 .…”

Factors associated with decision-making of replacing the temporary coronal restoration after endodontic treatment

et al. 2021

Aim: This study aimed to evaluate the decision-making by patients to replace temporary restorations with permanent restorations after endodontic treatment and to verify the associated factors and evaluate the quality/integrity of the temporary restorative material within one month. Methods: This is a cross-sectional study using non-probabilistic sampling which analyzed patients after one month of endodontic treatment. The self-administered questionnaire contained sociodemographic, treatment decision-making and endodontic treatment questions. The restoration present in the mouth was evaluated in the clinical oral examination. The Poisson Regression test was used to verify the prevalence ratio. Results: The prevalence failure to perform permanent restorations was 61.1% of patients, and 42.7% reported not having adhered. The reasons are lack of time and not knowing the importance of replacing the restoration with a definitive one. The glass ionomer temporary restorative frequency was higher among those who chose not to replace the temporary restoration with a permanent one (PR=5.19; 95%CI 2.10-12.33). In addition, there was an association between the quality of the restorative material and the type of material, and the best clinical quality of the restoration was statistically associated with glass ionomer and composite resin. Conclusions: The findings show the importance of guidance by the dental surgeon in helping patients decide to replace their temporary restoration.

“…Além disso, a associação do óxido de zinco ao sulfato de cálcio gera um aumento do selamento da interface no dente que foi utilizado o material restaurador. Isso acontece devido o sulfato de cálcio absorver água e como resultado aumentar seu volume PIEPER et al, 2009;KAMEYAMA et al, 2020).…”

“…Brazilian Journal of Health Review, Curitiba, v. 6, n. 6, p. 28390-28402, nov./dec., 2023 Após a realização do tratamento endodôntico, ou até mesmo quando não é possível realizar em sessão única, uma restauração temporária é necessária a fim de evitar a recontaminação do sistema de canais radiculares. Esse selamento temporário é de grande importância para manter esse sistema livre de infiltração marginal após obturado, e quando sob ação da medicação intracanal, os condutos continuem ainda em controle de sanificação (KAMEYAMA et al, 2020). Essa restauração temporária visa a manutenção da limpeza do canal radicular atuando como barreira física, impedindo a passagem de microrganismos para o interior dos condutos (JESUS E FERNANDES, 2022).…”

Apresentar uma revisão de literatura e comparar os materiais seladores temporários entre seus tipos principais e mais eficazes quanto à microinfiltração marginal, bem como suas vantagens e desvantagens na abordagem clínica. Trata-se de uma revisão de literatura utilizando as bases de dados da Pubmed Medline, Biblioteca Virtual de Saúde (BVS) e Scientific Electronic Library Online (SciELO). Para a busca inicial foram combinados os Descritores em Ciências da Saúde (DECs), isolados e cruzados: Materiais Dentários, Endodontia e Restauração Dentária Temporária onde forma incluídos os estudos publicados de 2000 a 2023, sem restrições quanto o idioma de publicação. Foram excluídas as referências duplicadas e estudos incompletos. Os materiais seladores temporários são uma barreira contra a contaminação bacteriana dos sistemas de canais radiculares de dentes que se encontram em tratamento endodôntico, ou que já concluíram o tratamento e estão na espera na restauração definitiva. Os principais materiais seladores temporários endodônticos são: obturadores pré-manipulados, os obturadores a base de ionômero de vidro, a base de óxido de zinco e eugenol e os resinosos fotoativados. Observou-se que as propriedades físicas e biológicas “ideais” dos materiais obturadores temporários ainda não foram alcançadas por nenhum fabricante estando os matérias obturadores temporários passiveis de microinfiltração coronária devendo as restaurações definitivas serem confeccionadas o mais breve possível após a terapia endodôntica, uma vez que caso ocorra um intercurso no material temporária, o canal obturado ficará exposto estando passível a recontaminação em um diminuto período.
