Article Synopsis
  • - The prevalence of oral, metabolic, circulatory, and nutritional diseases is rising globally, with common factors like unhealthy diets influencing their trends, prompting an evaluation of these issues in Colombia through government health records.
  • - The study aims to analyze the correlation between oral diseases (like caries and periodontitis) and systemic pathologies, as well as their links to socioeconomic factors in Colombian regions from 2016 to 2023.
  • - Results indicate that the average number of consultations for oral diseases was significant, with extensive caries being the most common issue, and a correlation was found between oral and systemic diseases, highlighting the impact of socioeconomic indices on health outcomes.

Introduction: Acquired pellicle (AP) acts as a membrane preventing acids from coming into direct contact with the tooth. Possibly, individuals with different dental health status present changes in its composition that could disrupt this function. Thus, the aim of this study was to compare the protein composition of the AP in adolescents with erosive tooth wear (ETW), caries, or sound.

Introduction: Healthcare workers (HCWs) are at the forefront of the COVID-19 response and frequently come into close contact with patients and their virus-contaminated body fluids. Recent studies have identified differential risks of infection and the use of personal protective equipment (PPE) among HCWs. However, available data might be interpreted with caution because of differences in the national health systems, local implementation issues, and adherence limitations to guidelines.

Objective: The aim of this study was to test the plausibility of using the ΦX174 bacteriophage as a tracer of viral aerosols spreading in a dental aerosol-generating procedure (AGP) model.

Methods: ΦX174 bacteriophage (~ 10 plaque-forming units (PFU)/mL) was added into instrument irrigation reservoirs and aerosolized during class-IV cavity preparations followed by composite fillings on natural upper-anterior teeth (n = 3) in a phantom head. Droplets/aerosols were sampled through a passive approach that consisted of Escherichia coli strain C600 cultures immersed in a LB top agar layer in Petri dishes (PDs) in a double-layer technique.

Infection control is critical for the safe delivery of dental care. Infection control practices must be responsive to emerging and re-emerging infectious diseases and outbreaks, as was clearly seen during the peak of the COVID-19 pandemic. An emerging global outbreak of the monkeypox virus has again raised potential challenges for infection control in dentistry.

Objective: To validate a questionnaire for the identification of factors associated with erosive tooth wear (ETW) in adolescents.

Materials And Methods: Based on previous questionnaires, a 73-question instrument was designed (four domains: socio-demographics, general/oral health history, diet and oral care habits). Content validity was assessed by five external experts, and the questions' understandability was evaluated in a pilot study (10 adolescents).

Background: Comprehensive caries care has shown effectiveness in controlling caries progression and improving health outcomes by controlling caries risk, preventing initial-caries lesions progression, and patient satisfaction. To date, the caries-progression control effectiveness of the patient-centred risk-based CariesCare International (CCI) system, derived from ICCMS™ for the practice (2019), remains unproven. With the onset of the COVID-19 pandemic a previously planned multi-centre RCT shifted to this "Caries OUT" study, aiming to assess in a single-intervention group in children, the caries-control effectiveness of CCI adapted for the pandemic with non-aerosols generating procedures (non-AGP) and reducing in-office time.

The objective of this clinical case study is to illustrate the caries management four-step structured process, leading to personalised interventions specific for each individual patient's risks and needs, according to CariesCare International, derived from the International Caries Classification and Management System (ICCMS) for clinical practice. An 18-year-old female was diagnosed with higher caries risk at the individual level, and with several caries lesions at different severity stages, some likely active and others likely inactive. A care plan was co-created with the patient and delivered to obtain optimal health outcomes.

More than 500 million people worldwide are infected each year by any of the four-dengue virus (DENV) serotypes. The clinical spectrum caused during these infections is wide and some patients may develop neurological alterations during or after the infection, which could be explained by the cryptic neurotropic and neurovirulent features of flaviviruses like DENV. Using and models, researchers have demonstrated that DENV can affect the cells from the blood-brain barrier (BBB) in several ways, which could result in brain tissue damage, neuronal loss, glial activation, tissue inflammation and hemorrhages.

In this work, we established an in vivo murine model of herpes simplex virus type 1 (HSV-1) infection involving inoculation by scarification of the oral mucosain order to study its dissemination towards the trigeminal ganglion (TG). Both viral DNA and infectious virions were detected on the third day postinfection (p.i.
