PURPOSE: This study evaluated the diagnostic accuracy of the reverse contrast mode in intraoral digital radiography for the detection of proximal dentinal caries, in comparison with the original digital radiographs. MATERIALS AND METHODS: Eighty extracted premolars with no clinically apparent caries were selected, and digital radiographs of them were taken separately in standard conditions. Four observers examined the original radiographs and the same radiographs in the reverse contrast mode with the goal of identifying proximal dentinal caries. Microscopic sections 5 microm in thickness were prepared from the teeth in the mesiodistal direction. Four slides prepared from each sample used as the diagnostic gold standard. The data were analyzed using SPSS (alpha=0.05). RESULTS: Our results showed that the original radiographs in order to identify proximal dentinal caries had the following values for sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, respectively: 72.5%, 90%, 87.2%, 76.5%, and 80.9%. For the reverse contrast mode, however, the corresponding values were 63.1%, 89.4%, 87.1%, 73.5%, and 78.8%, respectively. The sensitivity of original digital radiograph for detecting proximal dentinal caries was significantly higher than that of reverse contrast mode (p<0.05). However, no statistically significant differences were found regarding specificity, positive predictive value, negative predictive value, or accuracy (p>0.05). CONCLUSION: The sensitivity of the original digital radiograph for detecting proximal dentinal caries was significantly higher than that of the reversed contrast images. However, no statistically significant differences were found between these techniques regarding specificity, positive predictive value, negative predictive value, or accuracy.

OBJECTIVES: Diabetes is a chronic disease which is common in menopause period. Performing self-care behaviors is effective method for control of diabetes. This study aimed to investigate the effect of counseling on self-care behaviors in menopause diabetes women in 2016 in Hamadan, Iran. METHODS: In this study, 80 menopausal women were randomly selected and allocated to the experimental and control groups (40 per group). Data collected by a questionnaire included of demographic information, self-care behaviors, fasting blood sugar (FBS) and glycosylated hemoglobin (HbA1c). In the experimental group, training program was run during four sessions in the form of weekly group consulting sessions. During this period, the control group only received routine cares. Three months after intervention (group consultation) self-care behaviors, FBS and HbA1c were compared between two groups. Data were analyzed using SPSS 16 software. RESULTS: The self-care score in the experimental group increased from 49.6 ± 12.2 before the intervention to 66.6 ± 9.3 after the intervention (P < 0.05). Also in the control group average of self-care score changed from 57.6 ± 11.5 to 62.0 ± 11.6 (P < 0.05). Three months after the group consultation, there was a significant difference between two groups in the dimensions of diet (P = 0.013), exercise (P = 0.009) and foot care (P < 0.001). In the experimental group, FBS decreased from 148.8 ± 62.4 mg/dL to 128.9 ± 46.3 mg/dL. Also, HbA1c changed from 7.2 ± 1.8 g/dL to 6.8 ± 1.6 g/dL three months after intervention (P = 0.058). No significant changes were observed in FBS and HbA1c in the control group. CONCLUSIONS: The results showed that group counseling promoted self-care behaviors and metabolic indices in menopausal diabetic patients.

OBJECTIVES: This study aimed to investigate the effect of counseling on quality of life (QOL) in postmenopausal women conducted in Hamadan, Iran in 2015. METHODS: In this quasi-experimental study, 80 postmenopausal women were randomly selected and allocated to case and control groups (40 per group). Data collection tool included questionnaires of demographic information and QOL during menopause, which were completed by the samples before the intervention. In the case group, training program was run during four sessions in the form of weekly consulting sessions for 45 to 60 minutes. Training program included familiarity with menopause symptoms, confrontation and self-care during this period. The control group, only received routine cares. Three months after intervention, information were collected in both groups. Data were analyzed using SPSS for Windows. RESULTS: Before the intervention, mean ± standard deviation for QOL in case group was 101.2 ± 31.4 and it was significantly decreased to 96.9 ± 27.0 after intervention (P < 0.05). While no significant change was observed in the control group (from 98.9 ± 35.5 to 102.3 ± 35.0, P = 0.443). Symptoms of physical (P = 0.033) and sexual (P < 0.001) dimensions significantly decreased in the case group. While significant increase was observed in terms of psychosocial (P = 0.049) and sexual symptoms in control group. CONCLUSIONS: Findings suggested impact of consulting on improvement of QOL during menopause. Supportive consulting can be a suitable approach for improving women's health, reducing problems and enhancing QOL in menopause period.

Objectives: The aim of this study was to compare morbidities and duration of surgery, as well as bone formation in alveolar defects reconstructed with symphysis bone combined with allograft and iliac crest bone graft in patients with cleft palate. Patients and Methods: This randomized clinical trial was performed with 22 patients with unilateral alveolar cleft with a follow-up period of 12 months. In 12 patients, alveolar defects were reconstructed with chin bone graft plus allograft (Group A), while for the other 10 patients, iliac bone crest was used as donor site (Group B). Duration of surgery as well as occurrence of morbidities and complications were recorded. In addition, conebeam computed tomographic (CBCT) scans were performed before surgery and 12 months after surgical procedures in order to compare bone formation between the two groups. Results: Postoperative CBCT demonstrated a mean bone fill percentage of 76.9% of the alveolar defect in Group A, compared with 77.0% in Group B. Paresthesia in the lower lip or chin did not occur in any patients of Group A. The mean duration of the surgical process was significantly shorter for Group A (40 minutes vs 76 minutes, P<0.001). In addition, patients in Group A regained normal gait faster than patients in Group B (1 day vs 9.5 days). Conclusion Mandibular symphysis bone graft in combination with allograft results in favorable outcomes in patients with unilateral alveolar clefts.
