Teeth are screened for periodontal disease using digitized images manipulated and annotated on a processor. A digitized radiographic image of a tooth shows locations of a bone boundary and a cemento-enamel junction (CEJ) of the tooth. The digitized radiographic image is marked on the processor with a location on the bone boundary and with a pair of CEJ points at opposite ends of the CEJ visible in the radiograph. A ratio between (a) a distance between the bone boundary location and the adjacent CEJ point as numerator and (b) a distance between the CEJ points as denominator is calculated on the processor and compared with a threshold ratio-value for a corresponding tooth from a database accessible by the processor. A calculated ratio-value which is greater than the database threshold ratio-value is indicative of periodontal disease in the tooth. The probability of the correct diagnostic decision is determined by the relative magnitude of the calculated ratio-value and the threshold ratio-value.

Methods and systems for periodontal disease screening

The preferred embodiments described herein provide a method and system for displaying medical data at an automatically-selected display resolution. In one preferred embodiment, medical data is automatically analyzed, and based on the analysis, a display resolution is automatically selected. The medical data is then displayed with the automatically-selected display resolution. By automatically selecting a display resolution based on an analysis of medical data, the appearance of medical data is optimized without conscious effort by a user. Other preferred embodiments are provided.
