This paper analyzes the golden ratio (1.618) and its application in facial and dental aesthetics, as well as in art and architecture. In dentistry and orthodontics, it is used to achieve harmonious alignment of the front teeth, optimizing smile aesthetics. In facial plastic surgery, it is employed to enhance symmetry and attractiveness; however, some studies indicate that beauty cannot be reduced solely to this ratio, as cultural and individual factors influence its perception. Finally, it concludes that the golden ratio is a useful tool, but it should be applied flexibly, taking into account the uniqueness of each case and patient expectations.

Role of genetics in class ll and clas lll skeletal malocclusions.

Class II malocclusions are manifested by maxillary prognathism, mandibular retrusion, or a combination of both; while class III malocclusions are characterized by maxillary retrusion, mandibular protrusion, or both. Both malocclusions have a multifactorial etiology that can be influenced by genetic and environmental factors. The objective of this article is to identify the genes involved in the manifestation of these growth alterations associated with skeletal class II and class III malocclusions. Methods and materials: the information search was carried out in the PubMed, EBSCO, and Google Scholar databases, considering articles published in the last 10 years. Results: 8 articles were selected. Conclusions: Class II malocclusions are associated with variants in the genes ACTN3, FGFR2, MSX1, and MYO1H. Class III malocclusions due to variants in the genes ADAMTSL, MYO1H, BMP3, GHR, FGF7, FGF10, SNAI3 and ADAMTS2.

Comparative Evaluation of Periapical Radiography and Cone Beam Computed Tomography in the Detection of Root Configurations in Premolars

Fri, 21 Feb 2025 00:00:00 +0000

The study evaluates the diagnostic accuracy of periapical radiography (PR) and cone beam computed tomography (CBCT) in the root canal configuration of upper first premolars. It is concluded that PR, although inexpensive and low in radiation, has limitations in complex anatomies, achieving an accuracy of 72%. On the other hand, the CBCT, with high-resolution three-dimensional images, achieved 96% accuracy, although it requires greater exposure to radiation. Both techniques are complementary depending on the complexity of the case.

The digital flow in dental specialties.

Sara Ávila , Ricardo García , Nicole Portelles — Fri, 21 Feb 2025 00:00:00 +0000

This study examines the applications of digital workflows in dental specialties, identifying the areas of greatest use and the tools employed. A bibliographic review was conducted in PubMed, selecting systematic reviews and meta-analyses published between 2019 and 2024, with open access in the top 25% of indexed journals. Out of 37 initial articles, 13 met the inclusion criteria. Tools such as intraoral and facial scanners, CAD/CAM systems, and 3D printing technologies are widely used in prosthodontics, implantology, orthodontics, and oral surgery, standing out for improving diagnostic precision, treatment planning, and clinical outcomes. However, challenges such as high costs, the need for specialized training, and limited evidence in areas like artificial intelligence hinder their widespread adoption. Despite these challenges, digital workflows continue to revolutionize modern dentistry, enhancing efficiency and patient experience. The studies highlight the need for further research and accessibility to maximize their impact.

Use of artificial intelligence for the analysis of retroalveolar radiographs

Fri, 21 Feb 2025 00:00:00 +0000

Periapical radiography is a fundamental tool in dental diagnosis, providing detailed images of periapical structures and helping to identify pathologies associated with dental units. However, the analysis of these images can be subjective and dependent on the professional's experience, which can lead to variations in the diagnosis. Artificial intelligence (AI) is a branch of computer science that focuses on creating systems and algorithms capable of performing tasks that normally require human intelligence. This includes processes such as learning, reasoning and self-correction. AI allows machines to emulate human behaviors, improve their performance and make decisions based on identified patterns. This experimental descriptive research will introduce different periapical radiographs obtained on accessible AI platforms, including academic and dental databases.
