“…When the dentist believes that the material has reached sufficient hardness, the spoon is removed from the mouth with extreme care to prevent the cast obtained from being altered. There are different classifications of impression materials, such as reversible and non-reversible hydrocolloids, and elastomers [1]. The former, unfortunately, do not appear to have stability over time, due to the presence of water.…”

The advent of new technologies in the field of medicine and dentistry is giving improvements that lead the clinicians to have materials and procedures able to improve patients’ quality of life. In dentistry, the last digital techniques offer a fully digital computerized workflow that does not include the standard multiple traditional phases. The purpose of this study is to evaluate all clinical trials and clinical randomized trials related to the digital or dental impression technique in prosthetic dentistry trying to give the readers global information about advantages and disadvantages of each procedure. Data collection was conducted in the main scientific search engines, including articles from the last 10 years, in order to obtain results that do not concern obsolete impression techniques. Elsevier, Pubmed and Embase have been screened as sources for performing the research. The results data demonstrated how the working time appears to be improved with digital workflow, but without a significant result (P = 0.72596). The papers have been selected following the Population Intervention Comparison Outcome (PICO) question, which is related to the progress on dental impression materials and technique. The comparison between dentists or practitioners with respect to classic impression procedures, and students open to new device and digital techniques seem to be the key factor on the final impression technique choice. Surely, digital techniques will end up supplanting the analogical ones altogether, improving the quality of oral rehabilitations, the economics of dental practice and also the perception by our patients.

“…However, not all variants used by the industry have the same ability to interact with dental tissues and some are definitely not very effective if not as desensitizers. Various formulas have been presented by toothpaste manufacturers to avoid oxidation, including recently one in which the incorporation of zinc phosphate has been proposed [ 27 , 28 , 29 ].…”

In recent years there has been a lot of talk about toothpastes with a particular chemical compound: stannous fluoride (SnF2). Its presence is currently still highly controversial, as the latter could have negative health effects. The different companies that produce toothpastes express its dosage in ppm. The purpose of this systematic literature review is to analyze all randomized clinical trials in the literature over the last 10 years and to draw clear results on the function of stannous fluoride, for this purpose the authors performed a Mann–Whitney U Test. Materials: The first analysis of the literature produced a number greater than 800 results, subsequently applying the inclusion and exclusion criteria, and following a manual analysis of the results, 26 manuscripts have been obtained. Results: From the results analyzed in this review, it could be shown that stannous fluoride does not present important contraindications, if not those commonly reported for fluorine. A meta-analysis on enamel loss has been conducted, it shows that SnF2 products provide better results with a p < 0.05 value. Conclusion: This compound could have significant effects in favor of erosion and recalcification of the enamel, on the biofilm formation, gingival inflammation, and in addition, it could be an important aid in the removal of tooth stains and halitosis.

Background and Aim: Disinfection of dental impression materials can alter their dimensional stability, which in turn can affect the accuracy of dental casts. This study aimed to determine the effect of three disinfectants on the dimensional changes of irreversible hydrocolloid impression materials and addition silicones. Materials and Methods: In this in vitro experimental study, forty alginate and 40 addition silicone impressions were made using special trays. The impressions were disinfected by the spraying method for 10 minutes except for the control group. Then, they were poured with type IV dental stone. The prepared casts were maintained for 24 hours in a similar condition. Next, the dimensions and the external distance between two dies were measured at three time intervals using a digital caliper with 0.01 mm accuracy, and the average values were recorded. The yielded measurements were compared with each other and with metal models. One-way ANOVA and one sample t-test (α=0.05) were used for data analysis. Results: No significant difference was observed between the groups (P>0.05). Comparison of all average dimensions of the casts with the metal model showed that none of the groups had a significant difference except for the alginate group that showed an increase in the height of the larger die. There was a significant difference in the rest of the dimensions (P<0.05). Conclusion: Disinfection of alginate and addition silicone impression materials with 0.5% sodium hypochlorite, Epimax, and Deconex did not have any significant effect on the cast dimensions.
