Aims: This study aimed to evaluate and compare the quality, accuracy, and readability of orthodontic retention-related information provided by five AI-based chatbot platforms: ChatGPT-4, Copilot, Gemini, MediSearch, and OpenEvidence. Methods: A set of 25 commonly asked patient-oriented questions on orthodontic retention was submitted to each chatbot. Responses were evaluated using five key metrics: EQIP (Ensuring Quality Information for Patients), Reliability Score, Global Quality Score (GQS), SMOG Readability Index, and Similarity Index. Mean±standard deviation values were calculated. Kruskal-Wallis and Dunn’s post-hoc tests were used to assess statistical differences. Results: MediSearch and OpenEvidence outperformed others in EQIP and Reliability scores. ChatGPT-4 generated the most original content with the lowest Similarity Index. SMOG readability was significantly better for ChatGPT-4, while MediSearch and OpenEvidence produced more technically complex language. Statistically significant differences (p<0.05) were found between platforms in EQIP, SMOG, and Similarity Index metrics. Conclusion: Performance among AI chatbots varies significantly in delivering orthodontic retention guidance. While medical-specific tools offer superior accuracy and reliability, general-purpose models like ChatGPT-4 excel in readability and originality. The results highlight the importance of matching AI platform selection with patient communication goals.

Background/Objectives: Sagittal split ramus osteotomy (SSRO) is a widely used method in the treatment of mandibular deformities. However, high parafunctional forces associated with bruxism can negatively affect stability at the osteotomy site. Botulinum toxin A (BoNT-A), which reduces masseter activity, is considered an additional approach to controlling these forces. Methods: In this comparative finite element study, five different fixation configurations were created on a three-dimensional mandibular model and evaluated under identical boundary conditions using both a 1000 N bruxism-related parafunctional loading and a standardized force-reduction scenario. The stress distributions and displacement amounts on the cortical bone, screws, and plates were examined in each model. Results: The stress distribution was more balanced in the model with double plates, whereas the stress and displacement values were found to be greater for fixations with single plates and only bicortical screws. Under the standardized force-reduction scenario, lower stress and displacement values were observed across all the models. Conclusions: Among the evaluated fixation configurations, the double-plate model demonstrated the most balanced stress distribution. Under the standardized force-reduction scenario, lower stress and displacement values were observed across all the models; these findings reflect the load sensitivity of the fixation constructs and should not be interpreted as evidence of clinical efficacy.

Aims: Genioplasty is a widely used surgical technique to correct chin deformities and improve facial harmony. Despite its clinical relevance, a systematic evaluation of influential studies and research trends in this field is lacking. This study aimed to identify and analyze the 100 most cited articles on genioplasty through bibliometric methods. Methods: A title-specific search using the keyword “genioplasty” was conducted in the Web of Science Core Collection on July 25, 2025, covering the years 1950 to 2025. A total of 403 articles were retrieved and ranked by total citation count. After screening titles and abstracts, the 100 most cited articles with a primary focus on genioplasty were selected by two independent reviewers. Extracted data included publication year, journal name, total citations, average citations per year, authorship, study design, and primary topic. Descriptive statistics were used for analysis. Results: Citation counts ranged from 13 to 86. Most articles were published after 2000, with a peak in the 2010s. The Journal of Oral and Maxillofacial Surgery (n=20) and Plastic and Reconstructive Surgery (n=13) were the most represented journals. The most common topics were surgical technique (n=45) and outcome evaluation (n=34). Retrospective (n=35) and prospective (n=25) cohort studies dominated, while randomized controlled trials were rare (n=3). Conclusion: This bibliometric analysis reveals the leading themes, study types, and journals in genioplasty research, offering valuable insight for future investigations in facial skeletal surgery.

Objective: This retrospective cross-sectional radiographic study evaluated panoramic infrazygomatic crest (IZC) length and compared values according to skeletal class and sex. The term panoramic IZC length was used to describe a two-dimensional linear measurement obtained on panoramic radiographs, rather than a three-dimensional bone corridor for miniscrew insertion. Methods: A total of 180 archived digital panoramic radiographs of patients aged 16–30 years were retrospectively collected and grouped equally by skeletal class and sex. Skeletal class was determined using previously recorded lateral cephalometric tracings based on ANB angle criteria: Class I, 0–4°; Class II, >4°; and Class III, <0°. Panoramic IZC length was measured bilaterally on calibrated panoramic images using ImageJ, and the bilateral mean was used for subgroup comparisons. Group differences were analyzed using one-way ANOVA, independent-samples t-tests, and two-way ANOVA. Results: Panoramic IZC length differed significantly across skeletal classes, with the highest values found in Class III and the lowest values found in Class II (p < 0.001). Mean panoramic IZC length was 5.81 ± 0.38 mm in Class III females and 6.16 ± 0.41 mm in Class III males, compared with 4.99 ± 0.36 mm in Class II females and 5.51 ± 0.40 mm in Class II males. Males showed significantly greater values than females (p < 0.01). The sex-by-class interaction was significant (p = 0.04). Intra-observer repeatability was excellent (ICC = 0.95). Conclusions: Panoramic IZC length varies according to skeletal class and sex, with higher values in Class III individuals and males. These findings provide preliminary comparative morphometric information from routinely available panoramic radiographs. However, panoramic IZC length should not be interpreted as a three-dimensional insertion corridor, and CBCT remains necessary when comprehensive anatomical planning, sinus proximity assessment, or extra-alveolar miniscrew trajectory evaluation is required.

Aim: This study aimed to retrospectively evaluate the effects of Platelet-Rich Fibrin (PRF) application on postoperative healing following tooth extraction or sequestrectomy in patients with a history of antiresorptive drug use.Materials and Methods: A total of 47 patients who underwent either tooth extraction (n = 33) or sequestrectomy (n = 14) with simultaneous PRF application were included. Patients were followed postoperatively at 1 week, 1 month, and 3 months. Wound closure status and presence of infection were clinically assessed. Demographic data, indications for drug use, and route of administration were also analyzed.Results: In the sequestrectomy group, primary wound healing was achieved in 78.6% of patients at week 1, whereas only 6.1% of the tooth extraction group achieved primary wound healing. No signs of infection were observed in either group at the first-week follow-up. By month 3, complete mucosal healing was observed in all patients who underwent tooth extraction, and no cases of Medication-Related Osteonecrosis of the Jaws (MRONJ) development were recorded in this group. In contrast, two patients in the sequestrectomy group experienced recurrence of MRONJ, one of whom also showed signs of infection. PRF application was associated with low infection rates, successful mucosal closure, and the absence of new MRONJ cases in the extraction group.Conclusions: PRF may serve as a beneficial adjunct in surgical management of patients receiving antiresorptive therapy by supporting wound healing and reducing complications. Further prospective, controlled studies are warranted to validate these findings.
