    Antimicrobial effects of several calcium silicate-based root-end filling materials
    (JAPANESE SOC DENTAL MATERIALS DEVICES, 2014) Damlar, Ibrahim; Ozcan, Erhan; Yula, Erkan; Yalcin, Muhammet; Celik, Salih
    The purpose of this study was to evaluate, in vitro, the antimicrobial effect of iRoot BP, iRoot BP Plus, and mineral trioxide aggregate (MTA) against Entercoccus faecalis and Candida albicans by using direct contact test. The materials were tested immediately after application to the microtiter wells and after setting for 1-day and for 7-days. Ten microliters of microbial suspension was added to each well for direct contact with each material for 1 h at 37 degrees C and 100% humidity. Then fresh media was added and, survival of bacteria and fungi was determined by using 10-fold serial dilution and inoculated onto agar plates. In fresh and 1-day samples all of tested materials showed statistically significant antimicrobial effects compared to control groups (p<0.05). In 7-day samples, there were no significantly differences compared to control groups. MTA, iRoot BP and iRoot BP Plus had similar antimicrobial efficacy against E. faecalis and C. albicans.

    Evaluation of the mandibular volume and correlating variables in patients affected by unilateral and bilateral cleft lip and palate: a cone-beam computed tomography study
    (SPRINGER HEIDELBERG, 2016) Celikoglu, Mevlut; Ucar, Faruk Izzet; Buyuk, Suleyman Kutalmis; Celik, Salih; Sekerci, Ahmet Ercan; Akin, Mehmet
    The aims of the present study were to evaluate the mandibular volume in patients affected by unilateral (UCLP) and bilateral cleft lip and palate (BCLP) and to compare the findings with a well-matched normal occlusion sample without cleft. The study sample consisted of 66 patients divided into UCLP (24 patients; mean age, 14.46 +/- 3.24 years), BCLP (17 patients; mean age, 14.28 +/- 2.85 years), and control (25 patients; mean age, 14.40 +/- 2.81 years) groups. The volume of the mandible including the condyle and the roots of the teeth and craniofacial measurements were performed using cone-beam computed tomography and analyzed using the one-way variance analysis and post hoc Tukey's tests. Regression analyses were used to evaluate the relationships of the measurements and the mandibular volume. Patients affected by UCLP and BCLP had similar craniofacial features (p > 0.05), including decreased SNB, Co-A, Co-Gn, Co-Go, and Go-Gn and increased ANB and SN-MP measurements compared to the control group. Both UCLP and BCLP groups had decreased values of mandibular volume compared to the normal occlusion group, while these differences were found to be statistically insignificant (p > 0.05). Co-Go (Beta = 0.420; p = 0.014) and Co-Gn variables (Beta = 0.708; p = 0.045) were positively correlated with mandibular volume, while SNB (Beta = -0.669; p = 0.044) and SN-MP (Beta = -0.358; p = 0.049) variables were negatively correlated (R (2) = 60.3 and p = 0.000). Mandibular volume insignificantly differs in cleft patients (p > 0.05), and the variables of Co-Go, Co-Gn, SNB, and SN-MP significantly correlate with the volume. This article investigates mandibular volume in patients affected by UCLP and BCLP that has never been investigated in the literature. The present study showed that both UCLP and BCLP groups had insignificantly decreased values of mandibular volume compared to the normal occlusion group.

    Paresthesia of the mental nerve stem from periapical infection of mandibular canine tooth: a case report
    (MOSBY-ELSEVIER, 2008) Ozkan, Birkan Taha; Celik, Salih; Durmus, Ercan
    Sensory disturbances such as paresthesia, anesthesia, hypoesthesia, and hyperesthesia may be present in the oral cavity. Paresthesia is defined as a burning or prickling sensation or partial numbness caused by neural injury. Paresthesia in dentistry can be caused by local or systemic factors. Local factors include traumatic injuries such as mandibular fractures, expanding compressive lesions (benign or malignant neoplasia and cysts), impacted teeth, local infections (osteomyelitis, periapical, and peri-implant infections), iatrogenic lesions after tooth extractions, anesthetic injection, endodontic therapy (overfilling and apical surgery), implantology, orthodontic surgery, and preprosthetic surgery. The main purpose of this case report is to present the treatment and resolution of a mental nerve paresthesia stemming from apical pathosis of a mandibular canine tooth and the follow-up of 3 years.
