Aim: The purpose of the present study was to evaluate the gender-related differences in the relationship between periodontal diseases and depression in male and female adults. Methodology: 171 females with periodontal disease (71 subjects with gingivitis and 100 subjects with periodontitis) and 168 males with periodontal disease (72 subjects with gingivitis and 96 subjects with periodontitis) were included in the study. Clinic periodontal parameters (probing pocket depth, gingival index, plaque index, and bleeding on probing) were used in the periodontal examination. Depressive symptoms were determined by the Beck Depression Inventory (BDI). According to BDI scores, 150 depressed subjects (77 females and 73 males) and 189 non-depressed subjects (94 females and 95 males) were present. Results: There were similar BDI scores observed in female and male participants. All periodontal parameters were higher in males than females. While plaque index and gingival index were higher in depressed females than non-depressed females, probing depth was similar in female subgroups. Besides, all periodontal parameters were similar in male subgroups. When the relationship between periodontal status and depression scores in women was evaluated, women with periodontitis had higher BDI scores than women with gingivitis. In male subjects, there was no difference in BDI scores in individuals with periodontitis and/or gingivitis. Conclusion: It can be said that depression is a risk factor that negatively affects periodontal status for females, who were more vulnerable to stress and pain than males.   How to cite this article: Uçan Yarkaç F, Göktürk Ö.

Aim: Rehabilitation of tooth losses with fixed prosthesis applications is still a highly preferred option today. Teeth are the most important components for chewing function, proper phonation, and aesthetics. The aim of the study is to examine the relationship between tooth loss and fixed prosthetic restorations in patients of different age groups and genders. Methodology: In this study, a total of 300 patients were studied to examine the relationship between tooth deficiencies and the number of fixed restorations applied with gender and age. These patients were divided into two gender groups, male and female, and six age groups, with n = 25 in each group. Fixed prosthetic restorations in the missing teeth and mouths of the patients were recorded on dental panoramic radiographs. Statistical analysis was conducted with the one-way ANOVA test. Results: Tooth loss and the number of prosthetic applications increased statistically with age, but no statistical difference was found with gender. The Independent samples t-test analysis of variances was used in this study ( p  < 0.05). Conclusion: Tooth loss increases in patients with age due to many factors. This problem should be prevented by popularizing preventive dental practices. Female patients with poor dental hygiene and tooth loss associated with hormonal changes in specific age ranges have increased.   How to cite this article: Keçeci M, Demirel MG.

Aim: The aim of this study was to investigate the impact of photon-initiated photoacoustic streaming (PIPS) and ultrasonic activator Ultra X (UX) on the extrusion of debris using the One Curve (OC) rotary system and the Reciproc Blue (RB) system in curved canals. Methodology: Ninety extracted mandibular first molar teeth were divided into six groups (n = 15), Group (1): OC with PIPS, (2) OC with UX, (3) OC with conventional needle irrigation (CNI), (4) RB with PIPS, (5) RB with UX, and (6) RB with CNI. The irrigation activation methods were used in the final irrigation with 2.5 cc of distilled water. The apically protruded debris was collected into pre-weighed Eppendorf tubes. By deducting the tube's initial weight from the final weight, the weight of dry protruded debris was calculated. Two-way ANOVA test was used to analyze the results statistically. Results: A significant difference was found among all groups ( p < 0.05). No statistically significant difference was found among the instrumentation systems, regardless of the irrigation technique employed ( p > 0.05).  The statistically significant difference was found among the PIPS, UX, and CNI irrigation systems, regardless of the rotary systems ( p < 0.05). CNI caused significantly less debris extrusion than the UX ultrasonic irrigation activation systems. Conclusion: The UX irrigation activation system caused the highest amount of debris extrusion in curved canals. PIPS can be preferred to ultrasonic devices as irrigation activation systems.   How to cite this article: Akman M, Bozkurt DA, Zogheib C.

Aim: The study was to examine rapid maxillary expansion (RME), semi-rapid maxillary expansion (SRME), and slow maxillary expansion (SME) compare the root resorptions occurring in the supporting upper first premolar teeth during treatment by using micro-computed tomography (micro-CT). Methodology: Thirty individuals that required maxillary expansion and upper first premolar tooth extraction were divided into three groups consisting of 10 individuals for RME, SRME, and SME. RME group, first premolar and first molar teeth with hyrax screw were activated ¼ tour twice daily with the banded hyrax appliances. SRME group, acrylic-bonded hyrax appliances were activated ¼ tour per morning and night until the opening of the suture. Upon the opening of the suture, it was activated ¼ tour per every two days until sufficient maxillary expansion was gained. SEM group, quad helix appliances were activated every 20 days. After 12 weeks of the retention period, the upper first premolar teeth were extracted. The teeth were scanned with Micro-CT (SkyScan 1172, Kontich, Belgium), and images were analyzed with a Dell Precision T5500 to determine the resorption crater volumes. Results: In all samples, the resorption craters were concentrated on the buccal surfaces of the tooth roots. The highest resorption craters volume, the total resorption volume, was observed in the RME group, followed by the SRME group, and the least resorption crater volume was detected in the SME group. Conclusion: Since the supporting teeth were exposed to more force on the root surfaces, the most resorption was seen in the RME group.   How to cite this article: Topal R, Gündüz Arslan S.

Aim: The aim of this in vitro study was to determine how different polishing kits affect the surface roughness of lithium disilicate glass-ceramic and to examine the effect of Streptococcus mitis and Streptococcus mutans on the adhesion of Streptococcus salivarius to the glass-ceramic. Methodology: A total of 96 lithium disilicate glass-ceramic specimens were prepared and divided into four groups: control, rough, D+Z polished, and OptraFine polished. A total of 16 subgroups were obtained based on four combinations of three bacteria. After adding artificial saliva to the surface, all specimens were incubated in suspensions prepared for bacterial combinations. Bacterial adhesion values in the colonies formed were obtained according to the colony-forming unit (CFU) system. Results: The highest Sa values were found for the rough group, followed by the OptraFine polished, D+Z polished, and control groups, but, except for the control group, the values were statistically similar ( p > 0.05). The difference between S. salivarius and the triple bacteria combination was statistically significant for the S. salivarius CFU values in the control group. The difference between S. salivarius, S. salivarius + S. mutans, and the triple bacteria combination groups was significant for the rough group ( p < 0.05). S. salivarius alone accumulated the most on all specimen surfaces. In the control group, a high level (r=0.6-0.8) of positive correlation was found between the S + Mit group and the S + Mit + Mut group. In the rough group, a high (r>0.8) positive correlation was found between the S + Mut and S + Mit + Mut groups in terms of S. salivarius adhesion. Conclusion: For lithium disilicate glass-ceramic material, polishing systems are not sufficiently efficient after the glaze layer has been removed.   How to cite this article: Kavaz T, Özdemir H.

Aim: This study aimed to evaluate the conditions and indications in which a research and training hospital directs outpatient and inpatient consultations to an oral and maxillofacial surgery clinic and to evaluate the expectations of physicians in the treatment and management of various conditions. Methodology: The outpatient and inpatient consultations directed from Tokat Gaziosmanpaşa University’s clinics and internal and surgical medical sciences services to the same institution’s Oral and Maxillofacial Surgery Clinic between January 2013 and January 2022 were included. The patient characteristics, the aims of and responses to the consultations, and the applied interventions were recorded and classified. The quantitative data were analyzed with a t-test, and the classified data were analyzed with cross-tables and chi-square tests. P values below 0.05 were considered significant. Results: The medical records and consultation notes of 178 patients (92 males, 86 females) were evaluated. Of the consultations referred, 97 were requested from Forensic Medicine, 23 from Oncology, 11 from Neonatology, 8 from Otorhinolaryngology, 6 from Orthopedics, 6 from Neurology and Neurosurgery, 5 from Pediatrics, 4 from Emergency Medicine, and 18 from other departments. When the contents of the consultation were examined, it was observed that most of them were requested for age determination, post-assault examination, and dental abscesses. Conclusion: The present study indicates that an oral and maxillofacial surgery clinic is in close interaction with many medical branches and disciplines, especially forensic medicine, oncology, otorhinolaryngology, and neonatology.   How to cite this article: Çolak S, Demirsoy MS, Erdil A, Keldal G, Altan A, Akbulut N.

Aim: This case report describes the restorative treatment process of a non-syndromic unilateral peg-shaped left mandibular central incisor. Case presentation: A 23-year-old female patient was admitted for aesthetic concerns related to the appearance of the anterior mandible and a peg-shaped incisor. The color selection was done on clean, hydrated teeth. The teeth were roughened with a minimal red belt bur, a 37% phosphoric acid gel was applied to the enamel for 30 seconds, and the teeth were washed with water for 30 seconds to remove the acid agent. Following the application of a universal adhesive to the surface according to the manufacturer’s instructions, the palatal and proximal walls were formed using a mylar strip and an A2B-colored resin composite. Then, polymerization of the restoration was completed using an incremental layering technique. After the removal of any excess restoration, low-speed finishing and polishing were done using aluminum oxide and flexible rubber polishing disks containing diamond particles. After the resin application, the treatment was completed. Conclusion: To achieve optimal results in the treatment of patients, restorative treatment can be recommended, considering the position and condition of the tooth. When choosing the most appropriate treatment for a patient, the advantages and limitations of each technique should be carefully explained, and the most conservative treatment should be recommended.   How to cite this article: Fidan M.
