“…In prosthodontics, only one study [18] compared the impact of 3× and 10× magnifications and demonstrated that the preparation of finished crowns with greater magnification resulted in more precise marginal adaptation, contrasting with preparations without magnification. This last study was based on the assumption that tooth preparation is the most relevant factor for marginal adaptation, referencing [26].…”

“…The sample size was determined bearing in mind the aim of this study and based on the assumption that there is a significant difference of 500 µm in the Thickness of the tooth preparation carried out with or without magnifying loupes, a standard deviation of 259.6 µm for the group, observed with magnifying loupes in another study [18], and a 95% confidence level; a minimum of 5 teeth was obtained for each group, using Open Epi ® software version 3.01 (San Diego, CA, USA). To obtain as representative a sample as possible, a total of 64 natural teeth were used.…”

Background: The use of magnification appears to offer advantages in dental preparation for fixed prosthetics and is widely employed in clinical practice, although it has not yet been thoroughly documented. Therefore, the primary objective is to determine the impact of magnification on the quality of finish lines during the performance of preparations for fixed prostheses. Methods: Sixty-four natural teeth were randomized into two groups: Group O (preparation without additional magnification) and Group L (preparation with Kitus® 2.5× magnifying glasses). The teeth were prepared for full crowns, and the finish lines were evaluated under the OPMI® PicoZeiss dental microscope at 10× magnification, based on the criteria of Continuity, Roughness, and Thickness. Results: There were no significant differences between the groups in any of the parameters evaluated. In Thickness, Group O had a median (IQR) of 600 µm (500; 800 µm) and Group L, 600 µm (400; 800 µm). Group L was Continuous in 64.8% of the cases, Slightly Continuous in 26.1% of the evaluations, and Not Continuous in 9.1% of the cases, thus having a slight advantage over Group O, whose values were 58.0%, 35.2%, and 6.8%, respectively. Group L was Polished in 71.0% of the cases and Rough in 29.0% of the evaluations, against 69.3% and 30.7% of Group O, respectively. These results were obtained using IBM SPSS ® software, version 29.0. Conclusions: The 2.5× magnification magnifiers demonstrated a slight positive impact on improving the quality of dental preparations for fixed prostheses. Nevertheless, since the results are not statistically significant, it is difficult to extrapolate them to the broader population.

“…Root canal treatment: (1) DOM can assist in diagnosis and treatment and improve outcomes. [19][20][21][22][23][24] However, it should be stressed that the role of DOM should not be artificially exaggerated, and its indications should not be expanded indefinitely. It is not always necessary to use DOM for the entire treatment process.…”

Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators’ insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.
