At what age was the antibiotic received that caused tetracycline stain on maxillary & mandibular incisors and permanent first molars?

The correct answer is: 1yo

Tetracycline stains on dental structures are caused by exposure to the antibiotic tetracycline during certain stages of tooth development. This typically happens from birth until approximately 8 years of age. Therefore, options B, C, and D are incorrect as they exceed the age window for tetracycline-induced stains. Option A is the most accurate answer as it falls within the critical period of tooth development for tetracycline staining.
