Summary
Apical periodontitis (AP) affects nearly half of the population in eight Hispanic American countries. Poor root canal treatment and restorations significantly contribute to post-treatment AP, highlighting the need for improved dental care.
Area of Science:
- Endodontology and Public Health Dentistry
- Epidemiology of Oral Diseases
Background:
- Apical periodontitis (AP) is a prevalent endodontic disease.
- Understanding its prevalence and associated factors in Hispanic American populations is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of primary and post-treatment AP in eight Hispanic American countries.
- To identify variables associated with AP in this population.
Main Methods:
- A multicenter cross-sectional study analyzed digital panoramic radiographs from 11,850 subjects.
- Teeth were assessed for periapical status, root canal treatment, caries, restorations, and other factors.
- Statistical analysis included chi-square tests and multivariable mixed-effects logistic regression.
Main Results:
- AP prevalence was high, affecting 51.5% of subjects and 5.5% of teeth.
- Post-treatment AP was observed in 42% of teeth and strongly associated with inadequate root canal fillings, coronal restorations, and intraradicular posts.
- Prevalence varied by country, with Ecuador and Argentina showing the highest rates.
Conclusions:
- The study reveals a high prevalence of AP across Hispanic America.
- Inadequate endodontic and restorative procedures are key drivers of post-treatment AP.
- Improving dental care quality and caries prevention is essential to reduce AP burden.

02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:08Prevalence and Incidence
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
