Crucial X-ray Examination in Dentistry: A Case of Hidden Carious Lesion in Tooth #20.

This clinical case demonstrates how timely and preventive radiographic examination enabled the early detection of a carious lesion in tooth #20, which appeared clinically healthy and asymptomatic. Periapical (PA) radiography identified the lesion before its progression into pulpitis. The patient, a 13-year-old female, reported no complaints and exhibited no visible signs of decay, underscoring the importance of regular diagnostic radiographs. Early diagnosis facilitated conservative restorative treatment, optimizing clinical outcomes and minimizing the risk of complications. This case emphasizes the value of preventive radiographic screening as part of routine dental examinations.
