Item Effect of A Calcium Phosphate-Containing Desensitizing Agent on Postoperative Sensitivity: A Split-Mouth, Randomized Controlled Study(2023) Kerimova Kose, Leyla; Yilmaz, Ayfer Ezgi; Yamanel, Kivanc; Arhun, Neslihan; 37865810Purpose: To evaluate the effectiveness of a calcium phosphate-containing-desensitizer (Teethmate Desensitizer - TD), caries type, subject age, and preoperative hypersensitivity on postoperative sensitivity (POS) after composite restorations on deep or extremely deep lesions. Methods: 50 subjects, having two teeth with deep or extremely deep caries, participated in this study. TD was applied randomly to one tooth of each participant, and all teeth were restored with composite resin (Filtek Z250). After 1 week, POS was evaluated according to NRS (numerical rating scale) and VAS (visual analogue scale) by using participant diaries. At 6 weeks, POS was assessed considering subjects' reports. The normality of data was analyzed with Shapiro-Wilk test. For analyses, Pearson's chi-squared test, Mann-Whitney U and the Wilcoxon Signed-Rank test were used, and the effect sizes (ES) were calculated (alpha= 0.05). Results: 47 of the participants completed the 6-week study. There was a small effect size noted for TD for NRS and VAS (P> 0.05, ES < 0.30). Also, there was no statistically significant difference between POS and subject age (P= 0.294, ES= 0.161), type of caries (P= 0.680, ES= 0.042) and preoperative sensitivity (P= 1.000, ES= 0.138) after the first week.Item Survival of Root Canal-Treated Teeth Adjacent to An Implant: A Retrospective Case-Control Study(2023) Sisli, S. N.; Gul Ates, E.; Ozcelik, T. B.; Yilmaz, B.; Revilla Leon, M.; 0000-0001-5685-4409; 0000-0002-6166-2601; 37839623; JJF-5618-2023Objectives: To evaluate the survival of root canal treated (RCT) teeth adjacent to an implant compared with that of RCT teeth of the same patient non-adjacent to an implant.Materials and methods: RCT tooth of each patient adjacent to an implant were included in the test group. The control group consisted of another RCT tooth of the same patient; the control RCT tooth was not adjacent to an implant and selected to be of the same type of the RCT tooth in the test group. 72 teeth of 36 patients with at least 4-year follow-up were included. In addition to survival, other clinical and demographic parameters investigated were age, sex, tooth type and position, presence of a crown, presence of retreatment, presence of a post-core, presence of adjacent edentulous area, presence of implant-supported fixed prosthetic restoration on the antagonist tooth and periapical health status. Pearson Chi-Square and Fisher Exact tests were used to compare the test and the control groups with categorical variables (alpha=0.05). Survival curves were obtained by the Kaplan-Meier method, and the Log-rank test was performed to compare the survival probabilities (alpha=0.05).Results: No significant difference in survival rates was observed between the test and the control groups (p = 0.72). Similarly, no significant relationship was found between the investigated clinical variables and the survival rates of RCT teeth (p>0.05). Survival times differed depending on the presence of an adjacent edentulous area (p<0.001) and the periapical health status (p = 0.026).Conclusions: RCT teeth with unhealed periapical tissues had a shorter cumulative survival time. Similarly, those adjacent to an edentulous area had shorter cumulative and complication-free survival times.Clinical Significance: This is the first study to determine the survival outcome of a RCT tooth adjacent to an implant compared to a non-adjacent one in the same patient. Being adjacent to an implant did not have a detrimental effect on the survival time and rate of RCT teeth.Item Comparison of Implant Survival Rates and Biologic and Mechanical Complications with Implant-Supported Fixed Complete Dental Prostheses Using Four and Six Implants(2023) Tamer, Yusuf; Ozcan, Isil; 37552199This study aims to compare the incidence of biologic and mechanical complication rates and the survival rates after at least 5 years of implants and implant-supported fixed complete dental prostheses (IFCDPs) placed during second-stage surgery using four and six implants. A total of 77 patients (33 men, 44 women) with a mean age of 60.6 +/- 8.8 years (range: 39 to 80 years) were included, and the total of 92 IFCDPs were classified into two groups: 51 received four implants, and 41 received six implants. No implant failed in the four-implant group (0/204), and one implant failed in the six-implant group (1/246), with no statistically significant differences (P > .05). One prosthetic failure occurred in the four-implant group (1/51), and one failure occurred in the six-implant group (1/41). Both groups experienced some technical and biologic complications, with no statistically significant differences between the groups (P > .05). For both groups, veneer or resin fracture was the most frequent mechanical complication, and mucositis was the most frequent biologic complication. The use of four or six implants may represent a predictable treatment option in the rehabilitation of completely edentulous patients with IFCDPs in the medium-term. Int J Periodontics Restorative Dent 2023;43:e157-e163. doi: 10.11607/prd.5997Item The Effect of Dental Pulp Stem Cells and L-PRF When Placed into The Extraction Sockets of Impacted Mandibular Third Molars on The Periodontal Status of Adjacent Second Molars: A Split-Mouth, Randomized, Controlled Clinical Trial(2023) Cubuk, Secil; Oduncuoglu, Bahar Fusun; Alaaddinoglu, Emine Elif; https://orcid.org/0000-0001-6718-3882; 35141806; AAH-5405-2020; F-3529-2010Purpose To compare the clinical and radiographic effectiveness of dental pulp stem cells (DPSCs) seeded onto L-PRF and L-PRF alone in the extraction socket of mandibular third molars. Methods This study analyzed 13 patients who required surgical removal of impacted bilateral mandibular third molars. The main outcome measures were the probing pocket depth (PPD) and clinical attachment levels (CAL) that were recorded for the adjacent second molars (LM2) at the baseline and 6 months after surgery. The secondary outcomes were radiographic vertical bone loss (VD) and relative bone density (rBD) distal to the LM2. Results Twenty-six LM2s were evaluated. After 6 months, the L-PRF and L-PRF + DPSC groups showed a significant reduction in PPD (1.65 +/- 1.01 mm and 1.54 +/- 0.78 mm) and CAL (2.23 +/- 1.45 mm and 2.12 +/- 0.74 mm), respectively. There was no difference between the groups for any periodontal parameters. No significant differences were found between the groups regarding the VD or rBD at the sixth month. Conclusions This study found that there was a significant improvement regarding the PPD, CAL, and VD measurements with the application of L-PRF, both alone and with the addition of DPSC, at the extraction socket. DPSC did not significantly contribute to the results compared to L-PRF therapy alone.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, Ayca
