Bitewing radiographs and dentists' treatment decisions.

Area of Science:

• Dental Public Health
• Cariology
• Restorative Dentistry

Background:

• Understanding the relationship between radiographic caries detection and clinical restorative decisions is crucial for effective dental practice.
• Previous research has explored caries progression and intervention timing, but specific data on general dentists' practices regarding radiographic findings is limited.

Purpose of the Study:

• To assess the relationship between radiographic evidence of dental caries and the timing of restorative intervention in permanent teeth among general dentists.
• To compare caries penetration scores in different age groups and evaluate dentists' approaches to potential caries reversals.

Main Methods:

• A retrospective study analyzed 7,338 bitewing radiographs from 387 patients over 10 years.
• Six faculty members independently assessed radiographs for caries and restorations on non-restored proximal surfaces.
• Caries penetration scores were compared between patients aged 20 and younger versus older patients.

Main Results:

• Patients 20 years and younger exhibited significantly lower mean maximum caries penetration scores before restorative treatment compared to older patients.
• On average, restorative treatment was initiated before radiographic changes reached the dentin across all age groups.
• No significant differences were found among dentists regarding the time between radiographic diagnosis and restorative treatment.

Conclusions:

• General dentists in this study tended to intervene restoratively before radiographic evidence of dentin involvement, especially in younger patients.
• The findings suggest that systematic remineralization strategies were not consistently employed, as evidenced by the restoration of teeth with apparent caries reversals.
• Further research is warranted to explore optimal timing for restorative interventions and the integration of preventive strategies like remineralization.
