Accuracy in marginal and/or internal adaptation of full-coverage fixed prostheses made with digital versus conventional impressions: an overview of systematic reviews and meta-analysis
(2023) Delgado Gaete, Bolivar Andres
Aim: The study aimed to verify compliance of the systematic reviews with the requirements established by the scientific community and demonstrate the validity and reliability of the systematic reviews conducted on the accuracy (marginal adaptation and/or internal adaptation) of the full-coverage fixed prostheses made with digital impressions versus conventional impressions. Methods: A search was performed for systematic reviews in three electronic databases, PubMed, Scopus, and Web of Science, as well as in the gray literature. In the search strategy, medical subject heading (MeSH) words were used in PubMed, and free terms were used for the titles and abstracts of each article. Each keyword was separated by the Boolean operator OR and later combined with the Boolean operator AND. Six systematic reviews were included for qualitative synthesis. To assess the methodological quality of the included systematic reviews, the AMSTAR 2 tool was used. Results: The search yielded 131 studies, of which 78 remained after removing duplicates. The title and abstract of each chosen study were assessed, and 22 articles were included for full-text reading. Finally, six studies were included, of which three studies were considered to have low confidence, while the other three were considered to have critically low confidence. In addition, the six SRs evaluated the adaptation or marginal fit, while only three studies measured internal adaptation. Conclusion: The use of digital impressions in single fixed prostheses maintains a marginal level within the limit of clinical acceptability; however, the methodological quality of systematic reviews is poor, according to the AMSTAR 2 tool.

Development of a mobile application for the integral care and attention of elderly people

In recent years, the number of people reaching stages of ageing has increased considerably, reflecting a serious public problem. It is not enough to reach long ages, but to guarantee the integral care and attention of each individual. Thus, taking into consideration the difficulties faced by the elderly, States implement social security programs that seek to support their development. Ecuador follows this trend and presents proposals that address a number of fundamental rights, which are considered priority health care services. Although the measures implemented maintain the health, this reality changes when moving from an urban to a rural scenario. This is justified by the fact that in Ecuador, specialists who care for the elderly constantly change their location and, therefore, their patients, rather than maintaining a non-standardized data record on paper, causing inefficiency and waste of time. For these reasons, this article explains a proposal for a mobile application that seeks to standardize and digitalize the collection of medical data from the elderly in rural areas in order to increase the efficiency of current medical processes. © 2020, Springer Nature Switzerland AG.

Dientes posteriores tratados endodónticamente: alternativas para su rehabilitación basadas en evidencia científica. Revisión de la literatura

The definitive restauration of an endodontically treated tooth (ETT) is essential to prevent a possible periapical reinfection, which determines its short- and long-term prognosis. The aim of this paper is to determine the survival rate and the type of restoration that should be prescribed in posterior teeth according to the loss of tooth structure. In order to be able to achieve this, a search was conducted using digital databases such as: Cochrane, Scopus and PubMed using certain inclusion and exclusion criteria; as well as a manual search performed using Google Scholar. As a result, thirty-four articles were obtained for full reading, from which two classifications emerged, which allowed the reviewers to join criteria and propose a new classification which will make life easier for the reader at the time of choosing the ideal restoration. For those teeth with minimal loss of structure, the treatment of choice is composite restorations (91.9% to 100% rate of success); in teeth with a moderate loss of dental structure the ideal treatment was the use of indirect restorations of partial or total coverage (92.4% to 98.95 rate of success) alongside a fiber post if deemed necessary, finally, in teeth with a great loss of dental structure alternative techniques should be chosen in order to preserve as much dental tissue as possible. It is necessary to recognize the available options at the time of choosing a type of restoration according to the requirements of the tooth, always considering to be as conservative as possible so as not to further weaken its structure.
Efecto del composite reforzado con fibras cortas y con fibras de polietileno sobre la resistencia a la fractura en premolares endodónticamente tratados
(Universidad de Cuenca, 2025-06-04) Armijos Freire, Sandra Daniela; Abad Salinas, Yulissa Raquel
Background: Previous studies have shown that endodontically treated teeth are at critically higher risk of fracture compared to vital teeth because tissue loss compromises the structural strength of the endodontically treated tooth. Objective: To determine the effect of short fiberreinforced composite and polyethylene fibers on fracture resistance in endodontically treated premolars, period 2023-2024. Methods: An in vitro cohort study was conducted with 40 maxillary premolars, of which 10 formed the control group (G4). Thirty teeth underwent endodontic treatment, standardized cavity preparations, and were divided into three restorative groups: (G1) Ribbond polyethylene fibers with flowable composite resin, (G2) Ribbond polyethylene fibers plus short fiber-reinforced composite, and (G3) only short fiberreinforced composite, with 10 teeth in each group. An oblique compressive load (30°) was applied until fracture. Results: Results show that intact premolars (control group, G4) showed the highest fracture resistance with an average of 440,710 ± 28,147 N. Among the experimental groups, the Ribbond fiber + everX Posterior group (G2) obtained the highest resistance (330,710 ± 27,475 N), followed by the everX Posterior group (G3) with 257,934 ± 57,124 N. The differences between the restored groups were statistically significant (P < 0.05), indicating a consistent variation in fracture resistance depending on the material used. The Weibull distribution reflected that group G2 presented the highest reliability (m = 11.644). Conclusion: The combination of Ribbond fiber with everX Posterior (G2) showed the highest strength, while Ribbond fiber alone (G1) had the lowest.
Photopolymerization devises light intensity relation with physical translucid barriers use
(2020) Villalta Mendoza, Fernando Mauricio
Abstract: Nowadays, the use of halogen or light emission diode (LED) devices in dental attention is constant for almost any oral treatment. The need of providing an adequate light intensity for a correct photopolymerization of the resinous materials is critical. Likewise, it is important to consider the biosecurity norms for avoiding cross-contamination by residues likely to be accumulated at the top of the light guide in contact with oral cavity fluids. Therefore, the use of translucid barriers at the top of the light guide is imperative to protect the health of the patient while providing a correct polymerization of the resinous materials. The present study analyzes the effect of using four translucid barriers in the light intensity of three dental lamps commercially available. The tested barriers are two of commercial availability, and two conventional plastic wraps. Results indicate a significant reduction of light intensity without affecting the requirements for a correct photopolymerization with any barrier. Differences among barriers points out a conventional plastic wrap as more suitable than commercially available barriers, considering only light intensity provided.
