“…Materials with higher plasticity help with the marginal adaptation of the material in the cavity and promote better bonding strength (Silva et al . ). However, the manufacturer did not reveal the composition of the plasticizer.…”

Aim To evaluate the inflammatory response and ability to induce mineral deposition through histological and immunohistochemical analysis for osteocalcin (OCN), osteopontin (OPN) and bone sialoprotein (BSP) of a new calcium silicate‐based cement, Bio‐C Pulpo (Angelus), compared to white mineral trioxide aggregate (White MTA‐Ang) (Angelus). Methodology Polyethylene tubes containing Bio‐C Pulpo and White MTA‐Ang as well as empty tubes were implanted into the dorsal connective tissue of 30 Wistar rats, which were arranged in five groups according to the period of analysis: 7, 15, 30, 60 and 90 days. After each experimental period, the tubes with surrounding tissue were removed and histologically processed to be analysed using haematoxylin–eosin and immunohistochemistry for the detection of OCN, OPN and BSP. The data were statistically analysed (Friedman's test) at a 5% significance level. Results The inflammatory response observed with Bio‐C Pulpo and White MTA‐Ang was greater after 7 and 15 days and decreased from 30 days onwards. No significant difference was found between the control, Bio‐C Pulpo and White MTA‐Ang at the different periods of analysis (P > 0.05). The immunolabelling for OCN, OPN and BSP was more intense for Bio‐C Pulpo and White MTA‐Ang after 60 and 90 days, but there was no difference between Bio‐C Pulpo and White MTA‐Ang at the different periods of analysis (P > 0.05). Conclusion Bio‐C Pulpo is biocompatible and induces immunolabelling of osteogenic markers such as OCN, OPN and BSP similar to White MTA‐Ang.

“…To overcome these drawbacks, different vehicles for applying the material and MTA formulations are constantly being studied (1). Recently, MTA Repair High-Plasticity (MTA-HP®; Angelus Indústria de Odontológicos S/A, Londrina, PR, Brazil) was introduced, wherein manufacturers replaced the distilled water accompanying the MTA with a plasticizer liquid, thus increasing its plasticity (1,3,4). The MTA-HP showed excellent biological properties compared to its precursor, white MTA-Angelus® (MTA-Ang; Angelus Indústria de Odontológicos S/A) (1), along with better push-out bond strength (3) and slightly higher pH (4).…”

New mineral trioxide aggregate (MTA) formulations are constantly introduced in the market, usually in a powder-and-liquid form. Bioceramic (Bio-C) Repair is a ready-for-use material suggested as substitute for MTA, but its properties need to be studied. This study evaluated the cytotoxicity, biocompatibility and biomineralization of Bio-C Repair compared to MTA Repair High-Plasticity (MTA-HP) and white MTA-Angelus (MTA-Ang). L929 fibroblasts were exposed to material-extracted (undiluted, ½ and ¼ dilutions; 6, 24 and 48h). Polyethylene tubes with material or empty (control) were implanted in the subcutaneous tissue of rats. After 7 and 30 days (n=8), the specimens were removed for analysis (hematoxylin-eosin, von Kossa and polarized light). Cytotoxicity data were statistically analyzed by two-way ANOVA, and biocompatibility data by Kruskal-Wallis and Dunn tests (p<0.05). The cells exposed to the materials had greater viability at most of the periods compared with control (p<0.05). The undiluted and ½ dilutions of MTA-HP extract showed higher cytocompatibility than Bio-C Repair at 6 h and with the ¼ dilution at 24 h (p<0.05); the white MTA-Ang showed higher cytocompatibility than Bio-C Repair at most of periods (p<0.05). The undiluted white MTA-Ang extract had higher cytocompatibility at 6 and 24h than MTA-HP, and with ½ dilution at 24h (p<0.05). The materials’ cytocompatibility was similar at 48h for most dilutions (p>0.05). At 7 and 30 days, the groups had moderate and mild inflammation, respectively (p>0.05). All materials showed positive structures for von Kossa and polarized light. In conclusion, Bio-C Repair had similar cytocompatibility to MTA-based materials is biocompatible and induces biomineralization.

“…Além disso, o MTA HP apresentou melhor resistência ao deslocamento do que o seu antecessor MTA branco 32 . Por apresentar tungstato de cálcio, como radiopacificador, o MTA HP pode ter contribuído para uma maior liberação de cálcio nos períodos iniciais 33 , promovendo maior biomineralização e auxiliando na resistência deste material 34 .…”

Objetivo: relatar um caso clínico de perfuração radicular causada por iatrogenia, em terço cervical e médio de um incisivo central superior, dente 21, com presença de lesão óssea periapical. Relato de caso: clinicamente, pôde-se constatar ausência de edema e fístula. Na avaliação da condição pulpar e dos tecidos perirradiculares, o dente apresentou dor na palpação, ausência de mobilidade e de dor em percussão vertical e horizontal. Após os exames de imagem obtidos por meio de tomografia computadorizada de feixe cônico (TCFC; Prexion 3D), constatou-se lesão perirradicular extensa, canal radicular obliterado e perfuração radicular em face vestibular após tentativa de acesso cirúrgico. Como escolha de tratamento, optou-se por recuperar o trajeto original do canal de maneira a obter acesso intracanal, realização do preparo químico-mecânico e obturação pela técnica do cone único, para posteriormente promover o selamento adequado da perfuração com MTA Repair HP (Angelus, Londrina, PR, Brasil). Após seis meses, o dente apresentava-se assintomático e, radiograficamente, observou-se o reparo da lesão periapical. Considerações finais: o correto planejamento, o conhecimento dos materiais utilizados e a abordagem terapêutica foram de suma importância para o manejo adequado do caso.
