UNASSIGNED: Objective: Thin supporting tissues may cause @entity1464 and esthetic problems in the anterior area. The objectives of this study were to present a simple and reliable radiographic technique to measure thickness of alveolar bone labial to mandibular incisors, and to establish a possible correlation of bone thickness with its tissue biotype. Method and Materials: A metal strip was placed over the @entity1464 of the mandibular incisor axis, and a perpendicular occlusal radiograph was taken of 51 @entity1 . @entity1 in routine orthodontic practice before any orthodontic treatment was started were distributed into three groups according to their periodontal biotype (A1, thin with < 2 mm keratinized @entity1464 ; A2, thin with > 2 mm; and B, thick with wide zone of keratinized @entity1464 ), as described by M  ller and Eger.1 Radiographs were scanned and thickness of gingival tissue and of bone at two levels (at the bone crest and at 3 mm below the bone crest) was measured to the nearest 0.1 mm. Measurements of soft tissue and bone thickness were compared and correlated. Results: Groups @entity3750 showed a significant difference in bone thickness at the bone crest. Correlation of @entity79 was only found in gingival biotype B at 3 mm below the bone crest level only (R = 0.290; P < .001). No other correlation between @entity79 was observed in any group. Conclusions: The radiographic technique proposed in this study is a simple and reliable method for calibrating the amount of buccal bone in the mandibular anterior area. It is a cheap and fast diagnostic tool that may help determine the amount of buccal @entity79 , and therefore avoid excessive radiation to @entity1 . Groups @entity3750 showed a significant difference in bone thickness at the bone crest. Although not significant, group A1 showed the lowest values of @entity79 , whereas group B showed the highest @entity79 . A clear correlation between thickness of bone and @entity1464 3 mm below the cementoenamel junction was found in group B.
