Screening panoramic radiographs in children: prevalence data and implications

Area of Science:

• Dentistry
• Pediatric Dentistry
• Radiology

Background:

• Radiographic screening of pediatric patients is common practice.
• The effectiveness and necessity of panoramic radiography for asymptomatic children require evaluation.
• Assessing the risk/benefit ratio of diagnostic imaging is crucial in pediatric care.

Purpose of the Study:

• To review the rationale for radiographic screening in asymptomatic pediatric patients.
• To determine the prevalence of specific dental conditions using panoramic radiographs.
• To evaluate the utility of panoramic radiography for routine pediatric dental screening.

Main Methods:

• Retrospective study analyzing panoramic radiographs.
• Inclusion of 849 randomly selected subjects aged 3-9 years.
• Evaluation by three independent observers for specific dental anomalies.

Main Results:

• Prevalence of supernumerary teeth: 2.4%.
• Prevalence of missing permanent teeth: 7.8%.
• Prevalence of ectopic eruption: 9.1%.
• Prevalence of jaw radiolucencies: 0.1%.
• Prevalence of jaw radiopacities: 0.1%.

Conclusions:

• Panoramic radiography is an inefficient method for screening asymptomatic children's dental needs.
• The prevalence of detected conditions does not justify routine panoramic screening in this population.
• Alternative screening protocols for pediatric dental assessments should be investigated.
