简要总结
The diagnosis and differentiation between periodontal diseases are currently based on the measuring and interpretation of full-mouth clinical and radiographic criteria. Thermography is a modern non-invasive imaging method in which the infrared radiation emitted by an object allows the mapping and analysis of the exact temperature distribution on the surface of the object. The produced thermal images correlate with variations in local blood supply and tissue metabolism. Thus, suggested to be a useful rapid and non-invasive tool for the diagnosis of periodontal diseases. However, the validity of this tool compared to standard tools should be evaluated.
详细描述
A total of 45 of consecutive patients attending the periodontology outpatient clinic will be examined using standard periodontal clinical parameters including; Plaque index (PI), Gingival index (GI), Probing depth (PD), Clinical attachment level (CAL), and standardized periapical radiograph, to identify patients with gingivitis, periodontitis, or healthy periodontium , these 45 patients will be clustered into 3 clusters consisting of 15 patients each to represent each category. The same patients will be examined using an infrared thermal camera (Fluke PTi120 Pocket Thermal Imager), the settings will be all according to the standards of infrared medical diagnosis then the acquired images will be analyzed with (Fluke SmartView IR Analysis Reporting Software and Mobile Application). The images will be interpreted to detect the temperature changes in each mm in tissues in order to determine the patients with gingivitis, periodontitis, or healthy periodontium by an investigator blinded to clinical diagnosis. Then the diagnostic sensitivity and specificity of thermographic images for diagnosis of periodontal diseases will be calculated

结局指标
主要结局
Determine the agreement of thermographic images for diagnosis of periodontal diseases
时间窗: 1 day
Determine the agreement of thermographic images for diagnosis of periodontal diseases through the following outcomes: * Sensitivity The proportion of true positives in diseased subjects= True positives/ (true positives + false negatives) * Specificity The proportion of true negatives in non-diseased subjects= True negatives/ (true negatives + false positives).
次要结局
- The temperature ranges for healthy periodontium, gingivitis and periodontitis(1 day)
