“…Limitations of the review include the heterogeneity of the results, as the selected articles used PLA in different printing methods and in different quantitative analyses, because few used the DLP (Park et al, 2020) and SLA (Park et al, 2020) compared to FFF (Lo Russo et al, 2021Cresswell-Boyes et al, 2018;Nagata et al, 2022;Charasseangpaisarn et al, 2022;Deng et al 2018;Ishida, Miura, Shinya, 2022;Riva et al, 2022), so that the results may tend towards a conclusion that PLA presents better properties when associated with a printing method than another. Another limitation is that there are in vitro studies (Park et al, 2020;Ye et a., 2021;Lo Russo et al, 2021;Liu et al, 2022;Park, Shin, 2018;Hong et al, 2021) and that two articles selected (Deng et al, 2018;Peng et al, 2018) by the database could not be included in the present review due to the inability to access the full reading of the texts in full. Furthermore, the selection bias of the different types of objects used in the studies shows the difficulty in comparing certain properties in different objects analyzed, so that direct comparison between the methods used is not possible.…”

“…Therefore, it is important that more research and studies are carried out and a greater number of articles are written so that future projects can clarify and highlight the importance of the clinical use of PLA and its advantageous properties in the various selected printing methods, in order to enable your job. It is also necessary to develop more in vivo studies on the topic of this systematic review, since the oral cavity cannot be fully simulated in in vitro studies as carried out in some articles included here (Park et al, 2020;Ye et al, 2021;Lo Russo et al, 2021;Liu et al, 2022;Park, Shin, 2018;Hong et al, 2021).…”

The aim of this systematic review is to evaluate, through the in vitro studies included, whether PLA has mechanical, chemical and biological properties that enable its clinical use in dentistry. An electronic search was carried out in the Pubmed, Science Direct, Embase and Scopus databases containing the terms ''polylactic acid'', ''3D printing'',''biomaterials'',''dental materials'', dental prosthesis and dentistry. The objective of the inclusion criteria was to cover articles written and published in English that focused on the use of PLA in the field of dental materials and biomaterials printed using the 3D method. Any articles that did not focus on the study of PLA polymer, as well as systematic reviews, book chapters, abstracts, letters and conference articles were excluded. 1814 references were found, which after applying the exclusion criteria resulted in the final inclusion of 13 articles for the review. Based on the studies included in this systematic review, it is possible to conclude that 3D printed PLA used as a dental material and biomaterial presents favorable mechanical, chemical and biological properties that indicate its potential clinical use.

“…This semi-crystalline thermoplastic bio-sourced polymer has gained popularity because of its biocompatibility and biodegradability [21]. Moreover, studies have shown that PLA polymer offers acceptable mechanical properties in some dental applications and meets the requirement of the International Organization for Standardization (ISO) 20795-1 standards [22]. This polymer is frequently employed as a biomaterial for medical and dental applications [23].…”

This study investigates the fluoride release, rechargeability and degradation behaviors of newly developed anticariogenic poly(lactic acid) (PLA) composites. The PLA composite with various concentrations (0%, 5%, 10%, 15% and 20% by weight) of glass ionomer cement (GIC) and sodium fluoride (NaF) were prepared using solvent casting method. The fluoride release, fluoride rechargeability and degradation behavior were evaluated. All experimental groups demonstrated fluoride-releasing ability. The highest level of fluoride ions released was found in PLA composite with sodium fluoride (PLA/NaF). Following the 28-day period, both groups showed a gradual reduction in fluoride ion released, ranging between 0.03 ± 0.01 and 0.53 ± 0.06 ppm, although remaining within the effective range for tooth remineralization. However, the rechargeability was only observed in PLA composite with GIC (PLA/GIC). Following an eight-week in vitro degradation test, all PLA/NaF groups displayed a significantly higher percentage of weight change and water absorption compared to the PLA/GIC and the control group. In SEM analysis, the formation of surface porosities was clearly noticed in all PLA/NaF. All specimens retained their structural integrity throughout the study. In conclusion, the newly developed PLA/GIC displays promising possibilities as an anticariogenic material. Furthermore, the rechargeability of these ions are repeatable, ensuring their long-term utility.
