Growth factor-containing products have been reported to increase implant stability and accelerate osseointegration. Concentrated growth factor (CGF) can be used for this purpose with the growth factors it contains. The aim of this study is to assess the effect of CGF on implant stability and osseointegration. Twelve patients with maxillary anterior toothless were included in the study. Implant cavities prepared in the study group were covered with CGF membrane before implant placement, but conventional implant placement was performed in the control group. Resonance frequency measurements were performed with the Osstell device intra-operatively, post-operatively, at the 1st week, and at the 4th week. The mean ISQ values were found to be 79.40 ± 2.604 for the study group and 73.50 ± 5.226 for the control group at 1st week, 78.60 ± 3.136 for the study group and 73.45 ± 5.680 for the control group at 4th week. The differences between the groups were statistically significant (p < 0.05). It was observed that the concentrated growth factor had positive effects on implant stabilization. The ISQ measurements at week 1 and week 4 were notably higher in the study group. Application of this material seems to accelerate osseointegration.

This study aimed to evaluate the effect of low-level laser therapy (LLLT) applied before mandibular third molar extractions on postoperative pain, swelling, and trismus. The study included 28 patients aged 18–45 years with bilaterally impacted mandibular third molars in similar positions, indicated for extraction based on clinical and radiographic examinations. Patients were divided into two groups: Group 1 received LLLT 10 min before surgery, while Group 2 (control group) underwent routine impacted tooth extraction after applying blue LED light. Measurements were taken preoperatively and at 24 h (T0), 48 h (T1), and 7 days (T2) postoperatively to assess the effects of LLLT on pain, swelling, and trismus. Statistical analysis was performed using the Jamovi 2.2.5 software. Due to the non-normal data distribution, the Friedman test was used for repeated measures within groups, while the Mann-Whitney U test was employed to compare the laser and control groups. The study included 23 female (82.14%) and 5 male (17.86%) patients, with a mean age of 21.34 ± 4.37 years. No statistically significant differences were observed between the laser and control groups concerning pain, trismus, and swelling at T0, T1, and T2 (p > 0.05). Within the limitations of this study, preoperative LLLT showed clinically acceptable effects on postoperative pain, swelling, and trismus. Further clinical studies are needed to evaluate the long-term success of LLLT.

Objective: The aim of this study is to evaluate the relationship between anatomical reference points used during orthognathic surgery and to minimize the risks of iatrogenic neurovascular damage. Materials and methods: This retrospective study included cone-beam computed tomography (CBCT) images involving the mandible from patients who visited Recep Tayyip Erdoğan University Faculty of Dentistry between January 2018 and September 2023. The age range of the included individuals was set between 18 and 80 years. Horizontal and vertical distances between mandibular anatomical structures, such as the lingula mandibula (LM), mandibular foramen (MF), antilingula (AL), and surrounding structures were measured using CBCT software. Individuals with intraosseous pathology, insufficient image quality, or a history of surgical/orthodontic treatment were excluded from the study. Results: A total of 240 hemimandibles from 120 patients were analyzed (55.83% female, 44.17% male; mean age: 46.78 ± 15.30 years). Significant differences were identified in LM positions according to different AL types. The LM was found to be more inferior and posterior relative to hill and ridge type ALs, while it was more anterior relative to plateau type ALs. In 26.25% of mandibular rami, AL was not detected. Conclusion: The position of the AL can serve as a guide in determining the osteotomy line during inferior vertical ramus osteotomy (IVRO). However, relying solely on AL as a reference point may increase the risk of inferior alveolar nerve (IAN) injury. Preoperative tomographic evaluations to determine the relationships among LM, MF, and AL can provide a safer approach in surgical planning, reduce complications, and help protect neurovascular structures.
