Radiographic evaluation of nutrient canals (NCs) in the mandibular anterior region using intraoral periapical radiographs (IOPARs) and to determine whether they can be used as a potential marker for hypertension (HT) and diabetes mellitus (DM).
Randomly selected 600 patients of 21-60 years age group (Group I: 200 HT; Group II: 200 DM; Group III: Healthy subjects) were considered. The case history was recorded including details for DM and HT (duration, type, and medication). Blood pressure was measured, followed by blood examination for blood sugar levels. Selected patients were subjected to IOPARs using CS-2100C machine by the paralleling technique. Selected radiographs were evaluated by two observers independently for the presence/absence, number, and location of NCs between #33 and #43. Data obtained were tabulated and subjected to statistical analysis using SPSS 20.0 statistical software and intergroup reliability was checked using Cohen's kappa test.
Evaluation of various parameters of NCs showed an insignificant interobserver bias. The incidence of NCs presence was noted maximum in Group II (93.5%), followed by Group I (88.5%) and III (44.5%). Of total 888 NCs found, maximum were found in Group I, followed by II and III. On comparing the incidence of NCs present among both genders and location in study groups, no statistical correlation was found.
Statistically significant increase in the incidence and number of NCs in Group I and II compared to controls can act as an adjunct diagnostic marker for the detection of DM and HT; although, no significant correlation was obtained between gender and location of NCs in different study groups. Furthermore, there was no significant correlation was found between the severity of disease and incidence of the presence of NCs.
使用口内根尖片（IOPAR）对下颌前部区域的营养管（NCs）进行影像学评估，并确定它们是否可作为高血压（HT）和糖尿病（DM）的潜在标志物。
随机选取600名年龄在21 - 60岁的患者（第一组：200名高血压患者；第二组：200名糖尿病患者；第三组：健康受试者）。记录病例史，包括糖尿病和高血压的详细信息（病程、类型和用药情况）。测量血压，随后进行血糖水平的血液检查。使用CS - 2100C机器通过平行投照技术对选定患者进行口内根尖片拍摄。两名观察者独立评估所选的根尖片，观察33号至43号牙之间营养管的有无、数量和位置。将获得的数据制成表格，并使用SPSS 20.0统计软件进行统计分析，使用科恩kappa检验检查组间可靠性。
营养管各项参数的评估显示观察者间偏差不显著。营养管存在的发生率在第二组最高（93.5%），其次是第一组（88.5%）和第三组（44.5%）。在总共发现的888条营养管中，第一组发现的最多，其次是第二组和第三组。比较两组性别间营养管存在的发生率及研究组中的位置，未发现统计学相关性。
与对照组相比，第一组和第二组营养管的发生率和数量在统计学上显著增加，可作为检测糖尿病和高血压的辅助诊断标志物；尽管在不同研究组中，营养管的性别和位置之间未获得显著相关性。此外，疾病严重程度与营养管存在的发生率之间也未发现显著相关性。
