Factors associated with tooth decay in children in the first grade of primary school in public schools in the municipality of Suarez Cauca from the perspective of legal guardians

2024-01-10T21:22:49-05:00

Dental caries is a multifactorial disease with a global prevalence greater than 50%. That arises from an imbalance between the tooth structure and the surrounding plaque, induced by endogenous microorganisms, systemic and local factors that influence its development. Lack of oral hygiene and poor diet contribute significantly to its high prevalence.
This problem persists as a challenge to global public health. With the aim of understanding and addressing the factors associated with caries in children, an investigation was carried out in Suárez, Cauca, considering their sociodemographic aspects.
For this purpose, surveys were implemented for the legal guardians and intraoral examination for the first degree students of these institutions. The research provide insights to help develop effective strategies to reduce the risk of caries and improve oral habits in primary school children

Morphological characterization of Artemia salina in its different developmental cycles and its application in biocompatibility testing

2024-02-22T10:55:06-05:00

Background: Artemia Salina is a tiny crustacean that can tolerate high salt concentrations and survive in low-oxygen conditions. It is sexually dimorphic, meaning it has both sexual and asexual life cycles. In its adult stage, it measures between 17-18 mm in length and is used in aquaculture and toxicity testing.

Objective: To determine the most suitable stage of development of Artemia Salina for biocompatibility testing.

Materials and methods: An in vitro experimental study was conducted using Artemia salina as a biomodel. Detailed observations were made of the life cycle of Artemia salina, from its cyst stage to adulthood.

Results: A culture and feeding protocol was established for its maintenance in the laboratory. Common dental biomaterials were used to evaluate their cytotoxicity in Artemia larvae.

Conclusion: Toxicity tests with dental biomaterials showed that both calcium hydroxide and zinc oxide-eugenol were toxic to Artemia larvae, with a mortality rate of 100% within the first 24 hours.

Prevalence and Morphological Patterns of Mandibular Asymmetries in a Mexican Population: A CBCT-Based Analysis

2025-06-12T21:06:08-05:00

Background: Mandibular asymmetries are complex craniofacial conditions that can impact facial esthetics, function, and psychosocial well-being. Accurate diagnosis is crucial for planning individualized orthodontic and surgical treatment.

Objective: To evaluate the prevalence, severity, and morphological classifications of mandibular asymmetries in a Mexican population using cone-beam computed tomography (CBCT).

Materials and methods: A cross-sectional study was conducted involving 231 patients aged 9–65 years from the orthodontic clinic at Universidad Autónoma de San Luis Potosí. Mandibular asymmetry was assessed using CBCT scans, categorized by the deviation of the mandibular symphysis (DMS) as mild (0–2 mm), moderate (2.1–5 mm), or severe (>5 mm). Severe asymmetries were further classified according to Obwegeser and Makek’s system. Descriptive and inferential statistics were used to analyze differences in condylar and mandibular dimensions.

Results: Among 231 participants, 18 cases (7.8%) presented with severe mandibular asymmetry. Asymmetry of the glenoid fossa (AGF) was the most common classification (38.89%), followed by hemimandibular elongation (HE) at 27.78%. Severe deviations predominantly occurred on the right side (61.11%). No statistically significant differences were observed between male and female participants in terms of asymmetry type or severity.

Conclusion: CBCT imaging provides detailed visualization for detecting and classifying mandibular asymmetries. AGF and HE were the most frequent morphological types in this Mexican population, with a predominance of right-sided deviation. These findings underscore the need for population-specific diagnostic protocols and highlight the clinical value of 3D imaging in asymmetry evaluation.

Keywords: Mandibular asymmetry; cone-beam computed tomography; craniofacial morphology; hemimandibular elongation; glenoid fossa asymmetry.

Artificial intelligence in Dentistry: Clinical Impact and future perspectives

2025-08-27T18:58:38-05:00

Artificial intelligence (AI) has shifted from being a promise to becoming a tangible reality across dental domains —imaging diagnostics, orthodontics, endodontics, periodontics, implantology, prosthodontics, and digital lab workflows— offering AI-augmented workflows that promise precision, predictability, and equity. Yet, the gap between "laboratory accuracy" and real-world clinical effectiveness persists. This editorial synthesizes current advances, limitations, and future directions for responsible adoption.
