Single Cone Obturation versus Cold Lateral Compaction Techniques with Bioceramic and Resin Sealers: Quality of Obturation and Push-Out Bond Strength.

Objectives: This study compared the obturation quality and push-out bond strength of single cone obturation (SCO) and cold lateral compaction (CLC) with AH-Plus and Sure Seal Root (SSR). Materials and Methods: This in vitro experimental study was conducted on 88 single-rootedsingle-canal teeth with straight roots that were randomly divided into four groups (n = 22). All teeth were decoronated and underwent cleaning and shaping. Obturation was performed with AH-Plus and SCO technique in group 1 (SAH), AH-Plus and CLC technique in group 2 (LAH), SSR and SCO technique in group 3 (SS), and SSR and CLC technique in group 4 (LS). The roots were then sectioned into 3-mm thick slices and underwent digital photography at x25 magnification to assess the quality of obturation in the coronal, middle, and apical thirds by Image J software. The PBS was measured by a universal testing machine. The mode of failure was also determined under a stereomicroscope. Results: The PBS was significantly higher in the LSS group than LAH and SAH groups, and also in the SSS group than the SAH group in all sections. The PBS in the LSS group was significantly higher than SSS in the coronal and middle thirds. Voids were significantly lower in LAH than in the SAH group in all sections. In LSS, voids in the coronal third were significantly lower than in LAH. In the middle third, voids in SSS were significantly lower than in SAH. The groups had no significant difference in the mode of failure (P > 0.05). The mean percentage of gutta-percha in the use of AH-Plus sealer was significantly higher than SSR (P < 0.05). The mean percentage of gutta-percha in the coronal third was lower than that in the middle and apical thirds (P < 0.05). Conclusion: SSR showed higher PBS and less voids than AH-Plus. High PBS of the CLC/SSR group showed that CLC should still be preferred to SCO, and in the case of using SCO, SSR should be preferred to AH-Plus.

Transabdominal ultrasound measurement of pelvic floor muscle mobility in men with and without chronic prostatitis/chronic pelvic pain syndrome.

OBJECTIVE: To investigate the pelvic floor muscle motion in men with and without chronic prostatitic/chronic pelvic pain syndrome using transabdominal ultrasound. No study has directly evaluated pelvic floor muscle mobility in individuals with and without chronic pelvic pain syndrome. METHODS: A convenience sample of 40 males participated in the study. Subjects were categorized into 2 groups: those with chronic pelvic pain syndrome (n = 20) and those without chronic pelvic pain syndrome (n = 20). The amount of bladder base movement on ultrasound (normalized to body mass index) was measured in all subjects and considered as an indicator of pelvic floor muscle mobility. RESULTS: Statistical analysis (independent t-test) revealed significant difference in transabdominal ultrasound measurements for pelvic floor muscle function between the 2 groups (P = .03, 95% CI -0.26 to -0.01). CONCLUSION: The results of this study indicate that pelvic floor muscle mobility differs in the 2 groups.

Association of oral manifestations with ulcerative colitis.

AIM: The study aims to document the oral lesions in patients with UC. BACKGROUND: Inflammatory bowel disease (IBD) is comprised of two chronic, tissue-destructive and clinical entities including Crohn's disease (CD) and ulcerative colitis (UC), both of which are immunologically based. PATIENTS AND METHODS: The population of the study includes fifty patients with UC, as the experimental group, and fifty patients without gastrointestinal disease as the control group. All patients had an oral examination and completed the relevant questionnaire. RESULTS: There was a significant statistical relationship among tongue coating (<0.0001), halitosis (<0.0001), and oral ulceration (0.001) in patients suffering from severe UC compared to the control group. Also there was a higher prevalence of oral manifestations in patients with moderate UC compared to that of control group; but taste change (0.001) was the only significant factor. Acidic taste and taste change were among the symptoms more commonly found in patients suffering from pancolitis (40% each). CONCLUSION: The results of the present study show that patients with UC had more oral signs and symptoms than the patients in the normal group. Further researches on oral lesions in UC are also recommended so that these diseases can be better understood.
