Item Use of Cone-Beam Computed Tomography in Diagnosis of An Otherwise Undetected Periapical Lesion in An Anomalous Tooth(2014) Gulsahi, Ayse; Ates, Ufuk; Tirali, Resmiye Ebru; Cehreli, Sevi Burcak; https://orcid.org/0000-0001-6487-3984; HGA-3970-2022; AAD-2907-2020; AAD-6138-2021Fusion is a developmental anomaly of dental hard tissues. Since dental fusion is characterized by irregular coronal morphology and a complex endodontic anatomy, endodontic therapy of such teeth may present a serious clinical challenge. Cone-beam computed tomography (CBCT) is a useful tool for the management of complex endodontic problems and dental anomalies. In the case presented here, a CBCT scan revealed morphological details as well as the severity of periapical infection that had not been visualized with conventional imaging techniques. The results obtained with detailed imaging led to a change in the treatment plan.Item Dentofacial Effects of Skeletal Anchored Treatment Modalities For The Correction of Maxillary Retrognathia(2014) Sar, Cagla; Sahinoglu, Zahire; Ozcirpici, Ayca Arman; Uckan, Sina; https://orcid.org/0000-0003-4966-9779; https://orcid.org/0000-0002-9250-3689; 24373654Introduction: The aim of this clinical study was to investigate the skeletal, dentoalveolar, and soft-tissue effects of 2 skeletal anchorage rationales for Class III treatment compared with an untreated Class III control group. Methods: Fifty-one subjects who were in the prepubertal or pubertal growth period were included in the study. In group 1 (n = 17), facemasks were applied from miniplates placed in the lateral nasal walls of the maxilla, and intermaxillary Class III elastics were applied from symphyseal miniplates to a bonded appliance on the maxilla in group 2 (n = 17). These skeletal anchored groups were compared with an untreated control group (n = 17). Lateral cephalometric radiographs were obtained at the beginning and the end of the observation periods in all groups and analyzed according to the structural superimposition method. Differences between the groups were assessed with the Wilcoxon signed rank test or the paired-samples t test. Results: The treatment periods were 7.4 and 7.6 months in groups 1 and 2, respectively, and the untreated control group was observed for 7.5 months. The maxilla moved forward by 3.11 mm in group 1 and by 3.82 mm in group 2. The counterclockwise rotation of the maxilla was significantly less in group 1 compared with group 2 (P < 0.01). The mandible showed clockwise rotation and was positioned downward and backward in the treatment groups, and it was significantly greater in group 2 compared with group 1 (P < 0.01). Changes in the maxillary incisor measurements were negligible in group 1 compared with group 2. A significant amount of mandibular incisor retroclination was seen in group 1, and a significant proclination was seen in group 2. The maxillomandibular relationships and the soft-tissue profiles were improved remarkably in both treatment groups. Conclusions: The protocols of miniplates with facemasks and miniplates with Class III elastics offer valid alternatives to conventional methods in severe skeletal Class III patients. However, the 2 maxillary protraction protocols demonstrated significant skeletal and dentoalveolar effects. The miniplate with facemask protocol is preferred for patients with severe maxillary retrusion and a high-angle vertical pattern, whereas in patients with a decreased or normal vertical pattern and retroclined mandibular incisors, miniplates with Class III elastics can be the intraoral treatment option. Therefore, the exact indication of the procedure should be considered carefully.Item Management of Bisphosphonate-Related Osteonecrosis of the Jaw With a Platelet-Rich Fibrin Membrane: Technical Report(2014) Soydan, Sidika Sinem; Uckan, Sina; 24075235Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a challenging complication resulting from the long-term application of bisphosphonates. In most cases, BRONJ occurs after a surgical procedure involving the jawbone. Currently, the management of BRONJ remains controversial, and there is no definitive treatment other than palliative methods. Platelet-rich fibrin (PRF) represents a relatively new biotechnology for the stimulation and acceleration of tissue healing and bone regeneration. This technical note describes the total closure of moderate bone exposure in persistent BRONJ in 2 weeks with a double-layer PRF membrane. PRF may stimulate gingival healing and act as a barrier membrane between the alveolar bone and the oral cavity. PRF may offer a fast, easy, and effective alternative method for the closure of bone exposure in BRONJ. (C) 2014 American Association of Oral and Maxillofacial SurgeonsItem Dental Anxiety and Fear: Relationship with Oral Health Behavior in a Turkish Population(2014) Yozugullu, Bulem; Gulsahi, Ayse; Celik, Cigdem; Bulut, Sule; https://orcid.org/0000-0002-5936-0196; 24392477; AAA-1576-2021; AAC-5448-2020The aim of this study was to assess fear and anxiety in dental patients. Five hundred patients were evaluated using the Modified Dental Anxiety Scale and the Dental Fear Scale, along with a questionnaire. Oral health status was assessed using the Decayed, Missing, and Filled Teeth (DMFT)/Decayed, Missing, and Filled Surfaces (DMFS) index. Statistic al analysis was performed (P <.05). Sex significantly affected dental anxiety (P <.05), and sex, marital status, having children, and time elapsed since last visit to clinician affected dental fear (P <.05). DMFT/DMFS scores were not related to dental anxiety or fear (P >.05). Female sex alone was a significant predictor of dental anxiety; female sex, adulthood, marriage, having children, and time passed since last visit to a clinician are significant predictors of fear.Item Maxillary Expansion Via Palatal Mini-Implants: A Preliminary Study(2014) Arman-Ozcirpici, Ayca; Yilmaz, Alev; Polat-Ozsoy, OmurObjective: This study evaluates the skeletal and dental effects of a mini-implant supported maxillary expansion (MISME) appliance that applied forces directly to the maxilla. Materials and Method: Records of 9 patients (5 female and 4 male patients; mean age = 12 years 8 months) with indications of maxillary expansion were included in this study. After insertion of four miniscrews (1.6 mm in diameter, 7 mm in length), an acrylic expansion device was bonded on the screws. Two miniscrews were placed in the anterior palate bilaterally, 3-4 mm lateral to the suture and 3-4 mm posterior to the incisive foramen. Two miniscrews were placed bilaterally between the second premolar and first molar roots in the palatal alveolus. The MISME appliance was activated with a semi-rapid protocol until the desired expansion was achieved. The average treatment duration was 97.1 +/- 62.2 days. Measurements from cephalometric, posteroanterior radiographs and dental casts taken before and after expansion were evaluated statistically. The nonparametric Wilcoxon test was used for not normally distributed parameters (i.e., Nperp-A), and the parametric paired t test was performed for normally distributed parameters. A finding of p < 0.05 was considered to be statistically significant. Results: Forward movement of the maxilla (p<0.05) as well as an increase in nasal and maxillary skeletal and dental widths (p<0.001) were observed in the sample group. Maxillary intermolar, intercanine, and palatal widths also increased (p<0.001) without buccal tipping of molars. A slight posterior rotation of the mandible was seen. Dentoalveolar measurements did not show any significant changes. Conclusion: The MISME appliance showed successful expansion of the maxilla without such side effects as buccal tipping of molars and bite opening. This appliance, which provides parallel expansion, can be a simple and economic alternative to transpalatal distraction.Item Camouflage Treatment of a Severe Open Bite Case(2014) Yilmaz, Alev; Arman-Ozcirpici, AycaItem Does an Alkaline Environment Prevent the Development of Bisphosphonate-Related Osteonecrosis of the Jaw? An Experimental Study in Rats(2014) Dayisoylu, Ezher H.; Ungor, Cem; Tosun, Emre; Ersoz, Safak; Duman, Mine Kadioglu; Taskesen, Fatih; Senel, Figen Cizmeci; 24368141Objective. To investigate the preventive effect of locally applied sodium bicarbonate on bisphosphonate-related osteonecrosis of the jaw (BRONJ). Study Design. Thirty-six Sprague-Dawley rats were divided into 4 groups. Animals in group I received 0.1 mg/ kg sterile saline 3 times per week for 8 weeks. Groups II, III, and IV received intraperitoneal zoledronate injection in the same manner with the same frequency and duration. The right first molar tooth was extracted in groups III and IV. One mL 8.4% sodium bicarbonate (SB) was applied to the extraction socket at the time of extraction in group IV. The effect of locally applied SB as an alkalizing agent was evaluated by histomorphometric analysis. Results. BRONJ was observed in none of the animals in the control groups, 67% of the animals in the tooth extraction group, and none of the animals in the local SB application group (P < .01). Conclusions. Administration of locally applied SB had positive effects on the prevention of BRONJ in animals, but further studies are required to verify the effectiveness of this form of treatment before its use in humans.Item The Effect of Temperature and Contact Time of Sodium Hypochlorite on Human Roots Infected with Enterococcus Faecalis and Candida Albicans(2014) Gulsahi, Kamran; Tirali, R. Ebru; Cehreli, S. Burcak; Karahan, Zeynep Ceren; Uzunoglu, Emel; Sabuncuoglu, Bizden; https://orcid.org/0000-0003-3510-7265; https://orcid.org/0000-0001-6487-3984; 23011474; AAX-5565-2021; AAD-2907-2020; AAD-6138-2021The aim of this study was to evaluate the effectiveness of 2.5 % NaOCl at different temperature and time intervals on Enterococcus faecalis and Candida albicans-infected human roots. A total of 112 root cylinders prepared from extracted single-rooted humans were infected by E. faecalis (Group A, n = 56) or C. albicans (Group B, n = 56); 3 root cylinders served as negative controls. Both groups were further divided into 6 subgroups according to three contact times (30 s, 1 min, 5 min) with NaOCl at two different temperatures (25 or 37 A degrees C). Microorganism growth was controlled at the 24th and 48th hours. Statistical analysis was performed using the Chi-square test. While NaOCl at 25 A degrees C for 5 min was the most effective irrigation regimen to eliminate E. faecalis (p < 0.001), NaOCl at 37 A degrees C for 5 min exhibited significantly superior antifungal properties (p < 0.05). At the same contact times, difference in the temperature of NaOCl did not affect the growth of either E. faecalis or C. albicans. As a result, the irrigation time of NaOCl was more effective than the temperature to eliminate E. faecalis, while pre-heating of NaOCl to 37 A degrees C increased its effectiveness on C. albicans at 5 min contact time.Item An Alternative Impression Technique for Complete Dentures(2014) Yilmaz, Burak; Ozcelik, Tuncer Burak; https://orcid.org/0000-0001-5685-4409; 24286641; JJF-5618-2023This article describes a technique for creating adequate space for an even thickness of polyvinyl siloxane (PVS) impression material at the periphery during complete denture impression making. A PVS border molding material is injected around the borders of a custom tray, a 17-mu m-thick stretch wrap film is folded into 4 layers, and a tray-shaped piece slightly larger than the size of the custom tray is placed on the tray covering the borders. After the border molding procedure is completed, the film is removed and the definitive impression completed with a medium-viscosity PVS impression material.Item Effect of Adhesive Systems on Microleakage in Endodontically Treated Teeth Restored with Glass Fiber Posts(2014) Ozdemir, Erdem; Gulsahi, Kamran; Korkmaz, Yonca; Erkut, Selim; Tuncer, Abidin Hakan; https://orcid.org/0000-0003-3510-7265; AAX-5565-2021The effect of adhesive systems on microleakage in endodontically treated teeth restored with glass fiber posts was studied. Forty carious and crack-free premolars were prepared using a stepback technique and obturated with gutta-percha. The endodontically treated roots were randomly divided into four groups (n = 10). Glass fiber posts cemented following adhesive luting agents; group 1: All Bond 3/Duo Link (ALB/DL), group 2: One-Step Plus/Duo-Link (OSP/DL), group 3: Panavia F 2.0/Panavia ED Primer II (PAN/ED), and group 4: Rely X Unicem (RU). All specimens were thermal cycled and stored in basic fuchsin solution for one week. The roots were sectioned horizontally into three sections: apical, middle, and coronal. The occlusal direction of each section was digitally photographed under a stereomicroscope. Dye penetration area was calculated as the basic fuchsin infiltrated surface divided by total dentin. The data were statistically analyzed using the Mann-Whitney U and Wilcoxon Signed Ranks Tests (alpha = 0.05). The mean area measurements were ranged between 0 and 3.7357. According to the Mann-Whitney U test, there was no significant difference among the groups and sections (p > 0.05). Intragroup comparisons showed a significant difference between coronal-apical and middle-coronal sections in Panavia group (p = 0.043) by Wilcoxon Signed Test. It was found that there was no significant difference among four groups and the apical, coronal, and middle sections. The only difference was found for the group of PAN/ED between coronal-apical and coronal-middle sections.
