Choricarcinoma co-existing with pregnancy is rare often misdiagnosed with great potential for hemorrhagic complications and death. We present a case of a 34-year-old woman diagnosed with choriocarcinoma in her 3rd pregnancy with vaginal and pulmonary metastasis. Her first episode of vaginal bleeding was in the third trimester which was misdiagnosed. She had spontaneous vaginal delivery at 34 weeks of a healthy neonate. She was refered to gyneoncology unit of our hospital 5 weeks into puerperium from a nearby State hospital due to continouos vaginal bleeding and a growth from the postero-lateral wall of the lower third of the vagina. She had five courses of EMA-CO regimen. Her beta-human chorionic gonadotropin (hCG) has fallen from pretreatment value of 168,266 mIU/ml to less then 5 mIU/ml by the 5th course and the metastaic lesion regressed. She however developed WHO Stage III Oral Mucositis (with Oroesophageal Candidiasis) due to the side effects of chemotherapy which was co-managed successfully with the oral medicine specialist. She was subequently discharged home with follow-up visits. The quantitative beta-hCG has remained undetectable during her follow-up visits. Choriocarcinoma co-existing with pregnancy is rare, diagnosis often missed and confused with antepartum hemorrhage. Early and correct diagnosis can be life saving. [https://www.selleckchem.com/GSK-3.html GSK-3 signaling pathway] High index of suspicion is needed to make the diagnosis. The role of chemotherapy and close follow-up with quantitative beta-hCG assays are key to survival.During and after cardiac resynchronization therapy (CRT) implantation, many adverse events may occur. We present an interesting and important patient with hemoptysis and massive focal alveolar hemorrhage in a patient after a successful CRT implantation. CRT implantation was completed without any problems. In the follow-up, complaints of cough and hemoptysis began 1 h after the procedure. On the PA chest X-ray, a ground glass image was found in the left upper zone. Thorax CT revealed focal alveolar hemorrhage in the left upper lobe anterior segmental lung parenchyma. The patient was followed up with medical treatment and discharged in good health.<br /><br /> To investigate the root canal anatomy and the incidence of fused roots in maxillary first molar (MFM) and maxillary second molar (MSM) teeth in the Turkish population and compare them to teeth with separate roots using cone-beam computed tomography (CBCT).<br /><br /> CBCT images of 616 MFMs and 703 MSMs were analyzed from 402 patients for the number of roots and the presence of fusion. The canal configuration of teeth with separate and fused roots was compared. Type of fusion and canal merging positions were determined. A P value of less than 0.05 was considered significant.<br /><br /> Five hundred and seventy-one (92.69%) MFMs had three separate roots, one (0.16%) had four roots and the incidence of root fusion was 7.14%. An additional mesiobuccal (MB) canal was present in 79.34% of the teeth with three separate roots. There was no merging of canals in 36 of 44 teeth with fused roots. The prevalence of fusion was higher in the MSMs (23.47%). The incidence of three and four separate roots in MSM teeth was 74.68% and 1.85%, respectively. The prevalence of additional MB canals in teeth with three separate roots was 53.14%. There was no canal merging in 60% of the fused rooted teeth. There were two-merged canals in 31.52% and multiple merged canals in 8.48% of the MSMs.<br /><br /> In the Turkish population, the incidence of root fusion in the MFMs and MSMs was 7.14% and 23.47%, respectively, with more canal merging in the MSMs.<br /><br />In the Turkish population, the incidence of root fusion in the MFMs and MSMs was 7.14% and 23.47%, respectively, with more canal merging in the MSMs.<br /><br /> This study aimed to compare the clinical efficacy and survival rates of the hall technique (HT), and conventional restoration (CR) for the management of occlusoproximal carious lesions in primary molars.<br /><br /> This clinical study observed 35 children (aged 4-8 years). Exclusion criteria included symptoms of pulpal or periradicular pathology or systemic conditions requiring special dental considerations. For each child, at least one tooth was treated with HT and one with CR. The primary outcome measures were minor and major clinical failure rates. Plaque and gingival scores of the teeth were also evaluated. Friedman test and Wilcoxon signed ranks test were used to compare the plaque and gingival index scores for each arm. Chi-square tests were used for comparisons of clinical outcomes, plaque-gingival index, and distribution of ICDAS categories among treatment arms (P &lt; 0.05).<br /><br /> Thirty-three of 35 (94.2%) participants returned for 1-year follow-up. HT showed statistically significantly higher treatment survival rate and fewer minor failures than CR (P = 0.040). The rate of major failures was minimal (2 of 84 teeth) and did not differ between treatments (P = 0.092). In both treatment groups, the gingival score and plaque score were significantly decreased at the 1-year follow-up (P &lt; 0.05).<br /><br /> HT was a more successful method for managing caries in primary molars than CR, both for symptoms of pulpal disease and longevity of the restorations. HT is a simplified method of managing carious primary molars using SSCs cemented with no local anesthesia, caries removal, or tooth preparation.<br /><br />HT was a more successful method for managing caries in primary molars than CR, both for symptoms of pulpal disease and longevity of the restorations.

During the cleaning and shaping, irrigation was performed with a total of 10 ml of 5.25% sodium hypochlorite and 2 mL of distilled water. Then sections were taken from the roots (3, 6 and 9 mm). Sections were examined on a stereomicroscope to determine the presence of cracks. Chi-square test was used for data analysis.<br /><br /> There was a significant difference between the groups in dentinal crack frequency (P &lt;.05). HyFlex EDM (13.3%) caused less dentinal crack than One Curve (26.7%) and Reciproc Blue (30%). No cracks were observed in the control group. When 3, 6, and 9 mm were evaluated within themselves, dentinal crack formation did not differ according to the groups (P &gt; 0.
