Insights

The overall prevalence of malocclusion in Indian children aged 8-15 is 35.40%. This systematic review highlights variations in malocclusion rates across demographics and regions in India.

Area of Science:

  • Dental Public Health
  • Epidemiology
  • Pediatric Dentistry

Background:

  • Malocclusion is a common dental condition affecting children's oral health and aesthetics.
  • Understanding the prevalence of malocclusion in specific populations is crucial for targeted interventions.

Purpose of the Study:

  • To systematically review and assess the prevalence of malocclusion in Indian children aged 8 to 15 years.
  • To identify demographic and regional variations in malocclusion prevalence.

Main Methods:

  • A systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
  • Searched PubMed and other databases for studies published after January 1, 2000, using Dental Aesthetic Index (DAI) or Angle's classification.
  • Data extraction and validity assessment were performed independently by two reviewers.

Main Results:

  • The pooled prevalence of malocclusion among 97,959 participants across 54 studies was 35.40%.
  • Higher prevalence was observed in males (36.20%), 13-year-olds (33.50%), urban populations (32.78%), and South India (39.58%).
  • The mean DAI score was 21.23, indicating a moderate level of malocclusion.

Conclusions:

  • The pooled prevalence of malocclusion in Indian children aged 8-15 is 35.40%.
  • Significant heterogeneity was noted in the assessment methods used across the included studies.
  • Findings underscore the need for standardized malocclusion assessment and public health strategies in India.

Teeth01:15

Teeth

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...

Prevalence and Incidence01:08

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

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
