[Radiological estimation of interradicular space of primary molar teeth]

Area of Science:

• Dentistry
• Oral Radiology

Background:

• Accurate assessment of the interradicular space in primary molars is crucial for diagnosing pathology and understanding tooth development.
• Radiographic evaluation is a common diagnostic tool in pediatric dentistry.

Purpose of the Study:

• To evaluate the feasibility of radiologically assessing the interradicular space of primary molar teeth using radiographs prepared for endodontic therapy.
• To determine if these specific radiographs provide sufficient detail for accurate analysis of bone structure and permanent tooth bud positioning.

Main Methods:

• Retrospective analysis of archived dental radiographs of primary molar teeth without caries.
• Radiographs were taken under conditions optimized for endodontic therapy needs.
• Assessment focused on periodontium, lamina dura, interradicular bone texture, and permanent tooth bud disposition.

Main Results:

• Radiographs prepared for endodontic therapy are insufficient for accurate radiological estimation of the primary molar interradicular space.
• The radiological appearance of the interradicular space varies significantly.
• A thin bone structure in the interradicular space was frequently observed and considered physiological when the lamina dura remained intact.

Conclusions:

• Endodontic therapy radiographs are not suitable for detailed radiological assessment of the primary molar interradicular space.
• The observed thin bone structure in primary molar interradicular spaces is typically a normal physiological finding, especially when the lamina dura is continuous.
