ABSTRACT
ABSTRACT Objective: To evaluate resin- and bioceramic root canal sealers affect postoperative intensity and pain occurrence. Material and Methods: From the electronic databases, PubMed, Cochrane Library, Embase, ISI have been used to perform systematic literature until September 2020. Electronic titles were managed using the Endnote X8 software. They performed searches with mesh terms. Two reviewers blindly and independently extracted data from studies that included data for data extraction. Results: A total of 186 potentially relevant titles and abstracts were found. Finally, four studies were included. Pain score was (RR = -0.20; 95% CI -1.09-0.68; p= 0.65). This result showed no statistically significant difference for the resin-based and bioceramic root canal sealers after 24 hours between the VAS scores. Conclusion: Postoperative pain was low in Patients requiring root canal retreatment and obturated with resin-based or bioceramic-based sealers without extrusion beyond the apex. No differences were observed between postoperative pain in resin-based and bioceramic root canal sealers 24 and 48 hours postoperatively.

Background and aim: Endoscopic sinus surgery owing to its satisfactory prognosis and low complication is considered as the first line of surgical procedure. Implant failure is often reported despite efforts in recent years. The purpose of this study was to review the factors leading to side effects in dental implantation of the maxillary sinus. Material and Methods: The systematic search was performed on electronic databases of MEDLINE, PubMed, Cochrane Library, Embase, ISI, Google scholar to find corresponding articles regarding dental literature during 2010 to 2019. Electronic title management was carried out by Endnote X9 software. Searches were based on the keywords of "dental implants", "Implants"," dental"," maxilla", "sinusitis". Results: The searched potentially relevant titles and abstracts were related to 294 articles, 104 of which were excluded due to lack of study inclusion criteria. At last, 11 articles were included into the final analysis. Postoperative sinusitis was found in 78 patients within 9 articles among 1195 patients. The implant failure was reported in 136 cases and the sinus membrane perforation in 185 sinuses within 11 articles among 1372 sinus lift procedures. Conclusion: The findings showed that the risk factors of sinusitis after implant surgery were Schneiderian membrane rupture and preoperative sinusitis, as well as smoking and residual bone height were the parameters elevating the dental implant failure risk.

Justificativa e objetivo: A cirurgia endoscópica do seio maxilar, devido ao seu prognóstico satisfatório e baixa complicação, é considerada a primeira opção cirúrgica. A falha do implante é frequentemente relatada, apesar dos esforços realizados nos últimos anos. O objetivo deste estudo foi revisar os fatores que levaram a efeitos colaterais no implante dentário do seio maxilar. Material e Métodos: A busca sistemática foi realizada nas bases de dados eletrônicas do MEDLINE, PubMed, Cochrane Library, Embase, ISI, Google Scholar para encontrar artigos correspondentes sobre literatura odontológica no período de 2010 a 2019. O gerenciamento eletrônico de títulos foi realizado pelo software Endnote X9. As pesquisas foram baseadas nas palavras-chave "implantes dentários", "implantes", "dentário", "maxila", "sinusite". Resultados: Os títulos e resumos potencialmente relevantes pesquisados foram relacionados a 294 artigos, 104 dos quais foram excluídos por falta de critérios de inclusão no estudo. Por fim, 11 artigos foram incluídos na análise final. Sinusite pós-operatória foi encontrada em 78 pacientes em 9 artigos entre 1195 pacientes. A falha do implante foi relatada em 136 casos e a perfuração da membrana sinusal em 185 seios, em 11 artigos, entre 1372 procedimentos de elevação sinusal. Conclusão: Os achados mostraram que os fatores de risco para sinusite após cirurgia de implante foram ruptura da membrana Schneideriana e sinusite pré-operatória, assim como tabagismo e altura óssea residual, os quais foram considerados parâmetros que elevaram o risco de falha do implante dentário.

Abstract Objective: To analyze data obtained from animal and human studies using stem cells. Material and Methods: Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, Cochrane Library, Embase, Information Sciences Institute (ISI), as well as Google Scholar were utilized and searched as available electronic databases to perform a systematic literature review of articles published between 2010 and 2019. The Endnote X9 for Windows was also employed to manage electronic titles and abstracts of the selected studies. Searches were conducted using keywords of "pulpal OR pulpal tissue OR pulpal vitality", "regeneration", "apical healing", "stem cells OR progenitor cells", and "mediated pulpal tissue". Consequently, 189 titles and abstracts endowed with potential relevance were discovered based on searches into manual and electronic sources. Ultimately, a total of six articles met the inclusion criteria in the present systematic review and meta-analysis. Results: Out of the six articles identified and selected, five studies were categorized as animal experiments and one article was nominated as a human clinical trial. The greatest bias risks were accordingly observed in the majority of animal examinations, but articles related to humans revealed decreased risks of bias, while the human clinical trial showed some concerns. Conclusion: Promising parameters testing functional pulp regeneration could be represented through stem cell transplants.

Abstract Objective: To systematically review the hyalinization of experimental tooth movement in humans and animals. Material and Methods: The electronic databases of MEDLINE, PubMed, Cochrane Library, Embase, Institute for Scientific Information, and Google Scholar were searched for performing a systematic review of the related literature published until 2019. Moreover, Endnote X9 software was utilized to manage electronic titles. The searches were fulfilled using keywords of "hyalinization," "orthodontic tooth movement" OR "OTM" AND "periodontal ligament" OR "PDL," "molecular pathways," AND "mechanical cell." Therefore, this systematic review was conducted based on the key consideration of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Forces ranged between 2.3 and 50 CN had been applied. According to the research design, incisors had been included in two experiments, whereas maxillary molars had been displaced by tipping forces in another rat examination. However, a majority of investigations had stated that hyalinization had firstly appeared within the first 24 hours. Moreover, the amount of prostaglandin-end peroxide synthase 2 (PTGS2) had been positively related to force term and size utilizing Western blotching. As PTGS2 had been included in the prostaglandin E2 (PGE2) metabolism, the up-regulation of PTGS2 gene expression could be connected with that of PGE2 emission. Conclusion: Gene expression in connection with force term and size and also the first signalling pathways were recognized utilizing protein-protein interactions (PPIs).

Abstract Objective: To use virtual computer-assisted planning in orthognathic surgeries through meta-analysis and systematic review. Material and Methods: This search took place between 2010 and 2019. The databases searched in this domain included MEDLINE, PubMed, Cochrane Library, Embase, ISI, and Google scholar. Accordingly, the abstracts of the articles were initially reviewed and the ones that had the most coordination with the study objectives were selected. Then, the full texts of the articles were examined; and finally, five studies were selected. In addition to reviewing the related literature, the results were extracted and entered into the meta-analyzer Stata V.14 to summarize the final results. Results: The sample size in this study was at a range from 6 to 28 patients and a total number of 85 patients had participated in the given investigations. As well, CT and CBCT were selected as imaging methods. Clinical imaging and analysis were also employed in computer-assisted planning in all five studies. Subsequently, surgical planning was performed and the virtual splint was designed while the planning time was 225 minutes and 145 minutes in two studies. Conclusion: The present results supported computer-assisted planning and the quality of scientific evidence.
