Comparison of the Internal Adaptation of Restorations Manufactured with Different Materi-als and Techniques

Abdurrahman Şahinbaş — 2025-12-31

Purpose: This study aimed to evaluate and compare the internal adaptation of restorations produced with different materials and techniques.

Material and Method: In the study, tooth 36 was prepared on a dental training model (Kavo Basic study model, KavoGMBH, Germany) by an experienced prosthodontist. Using computer-aided manufacturing methods, 10 feldspathic ceramic crowns (Cerec Blocs, Sirona, Bensheim, Germany), monolithic zirconia crowns (Ceramill ZI CAM, Amann Girrbach, Germany), zirconia frameworks (Aidite, Superfect Zir, USA), metal frameworks (Bego, Germany) by laser sintering, and metal frameworks (using conventional methods) were fabricated. The metal and zirconia frameworks were completed with superstructure ceramics (VITA, Germany) by an experienced technician. The restorations were placed on the prepared teeth, and a silicone replica of the cement gap was obtained using the replica technique with additive-type silicone impression material (Heraeus Kulzer, Germany). Sections obtained from replicas were measured at 10 points using a light microscope. Statistical analysis of the data was performed using SPSS (ver. 21.0; SPSS, Inc., Chicago, IL, USA). ANOVA and post hoc Tukey HSD tests were applied to the obtained data.

Results: A statistically significant difference was observed only between axio-occlusal measurement points (p<0.05).

Conclusion: The internal range values were measured at a clinically acceptable range value of less than 200 micrometers. The highest internal range values were observed in the occlusal region and the lowest values in the axio-gingival region. The mean value of the highest internal range was measured at the occlusal measurement point in the monolithic zirconium group. The lowest mean value of internal range was measured at the axio-gingival measurement point in the zirconia-supported ceramic group.

Effect of Antimicrobial Agent-Applied Brackets and Resins on Plaque Accumula-tion: An In Vivo Study

Nursel Arıcı — 2025-12-31

Objective: In order to prevent plaque formation during fixed orthodontic treatment, bracket and band surfaces have been coated with a selenium-containing antimicrobial agent, and the same agent has been incorporated into adhesive resin materials. The aim of this study is to evaluate and compare the clinical performance, in terms of plaque accumulation, of the combination of selenium-coated brackets and selenium-enhanced adhesive resin (research group) versus the combination of conventional brackets and light-cured adhesive resin (control group) during fixed orthodontic treatments.

Materials and Methods: Seventeen female subjects with skeletal Class I malocclusion were included in this study. A total of 142 selenium-coated brackets and 145 conventional brackets were bonded by the same researcher using a split-mouth design. Selenium-enhanced adhesive resin was used with the selenium-coated brackets, while a conventional adhesive resin was used with the conventional brackets. In all patients, the incidence of plaque accumulation was determined using a computerized image analysis system based on monthly photographic records during the first three months of fixed orthodontic treatment.

Results: After three months, the average plaque percentage in the selenium-coated bracket group was not significantly lower" veya "did not differ significantly compared to the conventional bracket group. In intra-group comparisons, time and jaw had a statistically significant effect (p < 0.05), while no statistically significant difference was found between the groups for the bonded teeth" veya "between the test and control teeth (p > 0.05).

Conclusion: No statistically significant difference in plaque accumulation was found between the selenium-coated and conventional bracket combinations.

Comparison of Anxiety and Pain Levels Before and After Dental Implant Surgery

Yunus Emre Çalık — 2025-12-31

Statement of the problem: Postoperative pain and dental anxiety remain significant clinical concerns following dental implant surgery. Although existing studies have evaluated pain and anxiety associated with implant procedures, most have primarily focused on the pain-anxiety relationship without comprehensively addressing the influence of systemic diseases. However, it is well established that systemic diseases may increase anxiety levels in individuals and negatively affect the healing process.

Objective: The aim of this study was to compare preoperative and postoperative pain levels in systemically healthy individuals and patients with systemic diseases undergoing dental implant surgery, to monitor the course of pain on the 1st, 3rd, and 10th postoperative days, and to assess the impact of anxiety during this period. Additionally, the study sought to determine the effect of systemic diseases on postoperative pain and dental anxiety.

Materials and Methods: A total of 83 individuals scheduled for dental implant surgery at Ordu University Faculty of Dentistry, Department of Periodontology, were included in this study. Participants were divided into two groups: patients with systemic diseases (n=40) and systemically healthy individuals (n=43). The Spielberger State-Trait Anxiety Inventory (STAI-I, STAI-II), Modified Dental Anxiety Scale (MDAS), and Visual Analog Scale (VAS) were administered preoperatively and postoperatively. Postoperative pain levels were reassessed on the 1st, 3rd, and 10th days. Data were analyzed using SPSS 24.0 software, and a p-value of <0.05 was considered statistically significant.

Results: The mean age of participants was 46.53±14.03 years, with significantly higher age observed in the systemic disease group (p<0.01). The highest pain scores were recorded on the 1st postoperative day, followed by a significant decrease on the 3rd and 10th days. Postoperative and 10th-day VAS values were significantly higher in patients with systemic diseases compared to healthy individuals (p<0.05). Anxiety parameters decreased over time in both groups; however, postoperative MDAS scores were significantly higher in the systemic disease group (p<0.05).

Conclusion: Although pain and anxiety levels decreased over time after dental implant surgery, systemic diseases were found to negatively influence these parameters. Patients with systemic diseases reported higher pain and anxiety scores throughout the follow-up period. Therefore, systemic conditions should be carefully considered in treatment planning, and providing preoperative information and psychological support is of clinical importance.

Evaluation of Nasolabial Soft Tissue Parameters After Subspinal Minimally Invasive SARME Using 3dMD Stereophotogrammetry

Nizami GAYIBOV — 2025-12-31

Objective: The aim of this study was to compare the effects of minimally invasive subspinal SARME (MISARME) and conventional SARME (CSARME) on nasolabial and facial soft tissue parameters using 3D stereophotogrammetry.

Methods: This prospective, randomized, double-blind study included 35 patients diagnosed with maxillary transverse deficiency. MISARME was performed in the study group, while CSARME was applied in the control group. Soft tissue changes were evaluated preoperatively and postoperatively at different time intervals using 3D stereophotogrammetry.

Results: The MISARME technique was found to cause more limited changes in nasolabial aesthetics, providing more stable outcomes particularly in the preservation of upper lip length. No statistically significant differences were observed between the groups regarding the nasolabial angle, nasal tip angle, columella height, and supratip break angle.

Conclusion: The minimally invasive subspinal approach is a reliable alternative that reduces surgical morbidity, preserves esthetic outcomes, and improves patient comfort. MISARME is recommended for adult patients with maxillary transverse deficiency who have high esthetic expectations.

Rare Hyalinized Variant of Oral Fibroepithelial Lesion: Case Report and Review of the Lite-rature

Safiye Pelin Şahiner — 2025-12-31

Benign fibroepithelial lesions of the oral cavity, commonly referred to as irritation fibroma, traumatic fibroma, or focal fibrous hyperplasia, represent reactive proliferations arising in response to chronic tissue injury. While their clinical and histopathological features are well established, hyalinized variants are exceptionally rare and sparsely documented in the literature. Here, we present a case of a hyalinized fibroepithelial lesion of the oral mucosa, initially presenting as a nonspecific pedunculated nodular mass. The lesion was surgically excised, and histopathological examination revealed dense collagen deposition with prominent hyalinization, confirming the diagnosis. A brief review of previously reported cases is also provided to highlight the diagnostic challenges and clinical implications of this unusual histological presentation. This report underscores the importance of considering hyalinized variants in the differential diagnosis of oral soft tissue lesions and reaffirms surgical excision with elimination of irritative factors as the treatment of choice.
