A distance exceeding 2 mm from the cementoenamel junction (CEJ) to the alveolar bone was observed on the proximal surfaces of the first molars of proportionally more 15‐year‐olds (101 subjects) than 13‐year‐olds (99 subjects). The measurements were performed on bitewing radiographs, and the methodologic error amounted to 3%. Recordings in excess of 2 mm were most frequent (0.27 and 0.23) for the distal surfaces of the maxillary molars.
