Antibacterial efficacy and effect of Morinda citrifolia L. mixed with irreversible hydrocolloid for dental impressions: A randomized controlled trial

Abstract

Aim:This study aimed to evaluate whether the extract of Morinda citrifolia L. mixed with irreversible hydrocolloid powder decreases microbial contamination during impression making without affecting the resulting casts.Materials and Methods:Twenty volunteers were randomly divided into two groups (n = 10). Group A 30 ml extract of M. citrifolia L diluted in 30 ml of water was mixed to make the impression with irreversible hydrocolloid material. Group B 30 ml deionized water was mixed with irreversible hydrocolloid material to make the impressions following which the surface roughness and dimensional stability of casts were evaluated.Results:Extract of M. citrifolia L. mixed with irreversible hydrocolloid decreased the percentage of microorganisms when compared with water (P < 0.001) but did not affect the surface quality or dimensional stability of the casts.Conclusion:Mixing the extract of M. citrifolia L. with irreversible hydrocolloid powder is an alternative method to prevent contamination without sacrificing impression quality.

One Plant, Many Uses: A Review of the Pharmacological Applications of Morinda citrifolia

“…Irreversible hydrocolloids are used in dentistry as a molding material in the confection of dental restorations. The use of M. citrifolia extract with hydrocolloid powder in the preparation of dental impressions decreased contamination by microorganisms, without harming the quality of the material (Ahmed et al ).…”

Evaluation of Morinda citrifolia (noni) fruit extract as a bone regenerative material in the treatment of periodontal intrabony osseous defects: Clinical and cone-beam computed tomography assessment

“…Over many years, Morinda citrifolia (noni) has been accounted as a crucial herb for its significant medicinal implications and has recently been added as a plant of interest in the field of dentistry. In endodontics as an irrigant,[ 6 ] caries inhibiting agent,[ 7 ] as a disinfectant when mixed with irreversible hydrocolloid impression,[ 8 ] and as a mouth rinse for gingivitis/periodontitis.

Atividades farmacológicas e sua relação com o estresse oxidativo de Morinda citrifolia L. (Rubiaceae): uma revisão integrativa

“…Em relação aos estudos que avaliaram a atividade antitumoral e citotoxicidade, 4 adotaram métodos in vitro (14,29%) (Sharma, et al, 2015;Sukamporn et al, 2016;Wang, et al, 2019;Rajivgandhi, et al, 2020), e 1 utilizou a associação de estudos in vitro e in vivo (3,6%) (Lim, et al, 2016). Para a atividade antimicrobiana houve pequeno predomínio de estudos in vivo (7,1%) em relação ao in vitro (3,6%) (Podar, et al, 2015;Ahmed, et al, 2015;Divia, et al, 2018), enquanto que para atividade antileishmania 2 estudos foram in vitro e in vivo (7,1%) (Almeida-Souza, et al, 2016a;Almeida-Souza, et al, 2018) e 1 in vivo (3,6%;) (Almeida-Souza, et al, 2016b). Outros três dos trabalhos foram sobre o efeito hipotensivo, hipoglicêmico e a diminuição da frequência cardíaca, in vivo, sendo dois estudos com humanos e um em animais (10,7%) (Wigati, et al, 2017;Algenstaedt, Stumpenhagen & Westendorf., 2018;Nowak, et al, 2019).…”

“…Três estudos realizados avaliaram atividade antimicrobiana na irrigação de canais radiculares de M. citrifolia, sendo observados redução na contagem média da Unidade Formadora de Colônias (UFC) de bactérias aeróbias e anaeróbias (Podar, et al, 2015) e prevenção de infecção causada por E. faecalis (Divia, et al, 2018). Ainda foi avaliado a eficácia antimicrobiana do extrato de M. citrifolia misturado com hidrocolóide irreversível para moldes dentais, sendo que as salivas dos pacientes que utilizaram esta moldagem apresentaram redução da contaminação por microrganismos, sem alterar a qualidade do material no molde final (Tabela 6) (Ahmed, et al, 2015).
