Prevalence and Incidence

1.9K
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.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Teeth

1.8K
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...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

350
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Observational Studies

11.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Summary

Preeruptive intracoronal dentin radiolucencies (PIER) affect 13.6% of children, with defects most common in mandibular first premolars. Early detection on orthopantomograms is crucial for preventing complications.

Area of Science:

  • Dentistry
  • Oral Radiology

Background:

  • Preeruptive caries are radiolucent defects near the dentinoenamel junction of unerupted teeth.
  • Orthopantomograms (OPGs) are frequently used in pediatric dentistry for developmental assessments and can reveal these defects.

Purpose of the Study:

  • To determine the prevalence of Preeruptive Intracoronal Dentin Radiolucencies (PIER) in unerupted permanent teeth using orthopantomograms.

Main Methods:

  • 1000 orthopantomograms from children under 12 were analyzed.
  • Prevalence of PIER defects was assessed based on age, sex, tooth type, and dental arch.
  • Data were tabulated and analyzed to calculate prevalence percentages.

Main Results:

  • Overall participant prevalence was 13.6%, with teeth prevalence at 1.20%.
  • Mandibular first premolars showed the highest defect prevalence (38.9%).
  • Lesions were predominantly on the mesial side (52.3%) and less than one-third of dentin thickness (53%).

Conclusions:

  • PIER defects are significant anomalies associated with unerupted teeth, requiring better understanding and clinical recognition.
  • These defects are often overlooked on radiographs but prompt diagnosis is vital to prevent complications.
