PURPOSE: Health care delivery systems in rural areas face numerous challenges in meeting the community's needs. There is a lack of adequate attention for this problem. This study aims to explore the challenges of the health care process in rural Iran according to health care providers' experiences. METHODS: This was a qualitative study that used the content analysis method. We selected a total of 21 health care providers based on purposive sampling. Data collection consisted of semi-structured individual interviews that were analyzed by qualitative content analysis. RESULTS: Data analysis led to the formation of one main category, the challenges of process of health care in rural society. Within this main category, we created the following subcategories: change in characteristics of the rural society, increase in complexity of the health care process, decrease in workforce efficiency, and decrease in propensity of people's care. CONCLUSION: The findings of this study indicate that the process of health care in Iranian rural society is changing rapidly with community health workers encountering new challenges. There is diminished efficiency in responding to the changing care process in Iran's rural society. Considering this change in process of care, therefore, the health care system should respond to these new challenges by establishing new health care models.

PURPOSE: The aim of this in vitro study was to determine the sensitivity and specificity of cone-beam computed tomography (CBCT) and digital periapical radiography in the detection of mesial root perforations of mandibular molars. MATERIALS AND METHODS: In this in vitro study, 48 mandibular molars were divided into 4 groups. First, the mesial canals of all the 48 teeth were endodontically prepared. In 2 groups (24 teeth each), the roots were axially perforated in the mesiolingual canal 1-3 mm below the furcation region, penetrating the root surface ("root perforation"). Then, in one of these 2 groups, the mesial canals were filled with gutta-percha and AH26 sealer. Mesial canals in one of the other 2 groups without perforation (control groups) were filled with the same materials. The CBCT and periapical radiographs with 3 different angulations were evaluated by 2 oral and maxillofacial radiologists. The specificity and sensitivity of the two methods were calculated, and P<0.05 was considered significant. RESULTS: The sensitivity and specificity of CBCT scans in the detection of obturated root canal perforations were 79% and 96%, respectively, and in the case of three-angled periapical radiographs, they were 92% and 100%, respectively. In non-obturated root canals, the sensitivity and specificity of CBCT scans in perforation detection were 92% and 100%, respectively, and for three-angled periapical radiographs, they were 50% and 96%, respectively. CONCLUSION: For perforation detection in filled-root canals, periapical radiography with three different horizontal angulations would be trustworthy, but it is recommended that CBCT be used for perforation detection before obturating root canals.
