Background: The detailed relationship between apical periodontitis and maxillary sinus mucosal thickening is still unknown. The aim of this study was to evaluate the association between maxillary posterior teeth periapical odontogenic lesions and maxillary sinus mucosal (MSM) thickening by using volumetric 3D CT analysis. Methods: A total of 83 subjects with apical periodontitis around maxillary posterior teeth and maxillary sinus mucosal thickening were selected. 3D models of maxillary sinus mucosa and apical lesions were reconstructed from CT, and their volume, mean diameter were calculated. Results: Mean MSM thickening was 8.81 ± 12.59 mm with an average volume of 5092.58 ± 7435.38 mm3. Men had higher MSM thickening than women. Mean diameter of apical lesion was 5.94 ± 2.68 mm; average volume was 200.5 ± 197.29 mm3. Mean distance between MSM and apical lesion was 1.83 ± 2.07 mm. Mucosal volume was the highest in the S1 and D1 configuration and the lowest in R3. Reducing the distance between apical lesion and MSM by each millimetre, the volume of MSM increases by 759.99 mm3. Conclusions: Volumetric CT analysis is a circumstantial method to evaluate the association between maxillary posterior teeth apical periodontitis and MSM thickening. This relationship is not related to the size of the apical lesion but depends on their anatomical position and the distance from the maxillary sinus mucosa.

Reduction of postoperative scarring after unilateral cleft lip cheiloplasty is a pertinent topic. Smaller scar formation results not only in a better lip function, but also - aesthetics. This systematic review aims to identify various supplementary treatment options which influence favourable scarring outcome after cheiloplasty. The systematic review was conducted following PRISMA guidelines and Cochrane methodologies, using databases including PubMed, ScienceDirect, The Cochrane Library, and Google Scholar. Articles published between 2012 and 2024 evaluating supplementary measures for reducing scar tissue post-unilateral cleft lip cheiloplasty were included. Studies were assessed for bias using the Joanna Briggs Institute Critical Appraisal Checklist, and outcomes were measured using Vancouver Scar Scale, Visual Analog Scale, Hollander Wound Evaluation Score, and scar width metrics. Nine studies were analysed, highlighting platelet-rich plasma and botulinum toxin A as effective in reducing scar width and improving aesthetics. Silicone-based products enhanced wound healing, while non-absorbable sutures and tissue adhesives showed superior outcomes compared to absorbable sutures. Overall, supplementary measures significantly improved postoperative scar appearance. The use of platelet-rich plasma or botulinum toxin injections in musculus oribucalaris oris during the cheiloplasty significantly improves postoperative scar formation outcome. Wound edges approximation by non-absorbable sutures or tissue glue equally results in smaller scar formation and better aesthetic outcome. Suturing with absorbable sutures increases the incidence of complications and results in poor aesthetics. Postoperative wound care with products containing silicone significantly reduces scarring and aids in aesthetics.

Background: Disorders of the temporomandibular joint (TMJ) affect millions worldwide and rank among the most frequent causes of orofacial pain unrelated to dental disease. Beyond discomfort, they can restrict mandibular motion and impair chewing efficiency. Arthrocentesis has been adopted as a favored surgical approach after conservative therapy fails since joint lavage can reduce inflammation and restore mobility with minimal invasiveness. A variety of irrigants are available for this procedure, including normal saline, Ringer’s lactate, and ozonated water, each offering potential therapeutic advantages. However, the comparative effectiveness of these solutions in terms of pain reduction and functional recovery has not been clearly established, warranting systematic evaluation. Materials and Methods: Following PRISMA recommendations, a literature search was conducted in PubMed and ScienceDirect between 10 October and 14 November 2024. The search focused on studies published in English within the past ten years that examined arthrocentesis for temporomandibular joint disorders using normal saline, Ringer’s lactate, or ozonated water as the irrigant. Results: Seven clinical trials involving 220 patients were included, of which three provided data suitable for meta-analysis. Qualitative synthesis indicated that all irrigants reduced pain (VAS) and improved maximum mouth opening (MMO), with ozonated water showing the greatest mean improvements (VAS reduction 6.2 points; MMO gain 12.9 mm). Ringer’s lactate and saline also demonstrated clinically relevant effects. Quantitative analysis revealed no baseline group differences (VAS p = 0.800; MMO p = 0.935). Short-term (≤1 month) random effects models showed non-significant changes for VAS (Fisher’s z = 1.32; 95% CI −2.64 to 0.00) and MMO (z = 0.04; 95% CI −0.14 to 0.21). At 3–6 months, ozonated water produced a statistically significant reduction in pain (z = −0.34; 95% CI −0.53 to −0.15), whereas MMO remained unchanged (z = 0.05; 95% CI −0.13 to 0.22). Conclusions: Arthrocentesis with any irrigant improves TMD symptoms. Ozonated water demonstrated the strongest long-term analgesic effect, but MMO improvements did not reach significance. Larger, standardized randomized trials are required to validate these findings.

Background: Magnetic resonance imaging (MRI) is the reference standard for evaluating temporomandibular joint (TMJ) disorders, particularly for assessing disc position, joint effusion, and degenerative changes. With increasing imaging demands and advances in deep learning, artificial intelligence (AI) has emerged as a potential adjunct to expert interpretation. This systematic review aimed to compare the diagnostic performance of AI-based models with that of human experts in TMJ MRI analysis. Methods: This review was conducted in accordance with the PRISMA 2020 guidelines and prospectively registered in PROSPERO (CRD420251174127). A systematic search of PubMed/MEDLINE, ScienceDirect, Wiley Online Library, and Springer Nature Link was performed for studies published between 2020 and 2026. Eligible studies included human participants undergoing TMJ MRI and evaluated AI, machine learning, or deep learning models against human expert interpretation. Extracted outcomes included sensitivity, specificity, accuracy, area under the receiver operating characteristic curve (AUC), and agreement metrics. Risk of bias was assessed using QUADAS-2. Due to substantial heterogeneity, a narrative synthesis was conducted. Results: Five retrospective diagnostic accuracy studies were included, comprising sample sizes ranging from 118 to 1474 patients. Target conditions included anterior disc displacement, joint effusion, osteoarthritis, and disc perforation. AI models demonstrated strong discriminative performance, with reported AUC values ranging from 0.79 to 0.98. In direct comparisons, AI achieved diagnostic accuracy comparable to experienced radiologists. AI systems frequently demonstrated higher specificity and similar overall accuracy, whereas human experts often showed higher sensitivity. In osteoarthritis assessment, AI performance approached expert level and exceeded that of less experienced readers. All studies were retrospective and predominantly single-center, with heterogeneous reference standards and limited external validation. Conclusions: AI achieves diagnostic performance comparable to experienced clinicians in TMJ MRI interpretation and shows promise as a decision-support tool. Nevertheless, it should be regarded as complementary to, rather than a replacement for, expert radiological assessment pending further rigorous validation.

Relevance of the problem and aim of the work: Ankylosis of the temporomandibular joint (TMJ) affects physical, psychological, and social well-being and quality of life. One of the most frequently used surgical interventions for the treatment of temporomandibular joint ankylosis is interpositional arthroplasty, particularly in cases where joint preservation is feasible, with different autologous fats: dermis fat, buccal fat pad, and full thickness skin-subcutaneous fat. The aim of the work was to evaluate the efficiency of using different autologous fats in temporomandibular joint ankylosis treatment with interposition arthroplasty method. Materials and Methods: This systematic literature review was conducted according to PRISMA guidelines and registered in the PROSPERO database (CRD420251038325). A comprehensive search was performed in PubMed, the Cochrane Library, and ScienceDirect databases using combinations of keywords: (temporomandibular joint disorders OR temporomandibular joint) AND (adipose tissue or autologous) AND (ankylosis OR arthroplasty). Inclusion criteria were clinical studies conducted on human subjects, written in English, that evaluated the use of autologous fat in interpositional arthroplasty for TMJ ankylosis. The main outcome measures included postoperative maximum mouth opening (MMO), pain intensity, and relative fat volume contraction. Risk of bias was assessed using the Cochrane RoB 2 tool for randomized controlled trials and the Newcastle–Ottawa Scale for cohort studies. Most included studies were of moderate to high quality. Results: A total of 20 publications were selected, including a total of 369 patients. In a qualitative analysis, the best results for maximal opening of mouth (MOM) at 3, 6, 12, and more than 12 months were obtained with dermal fat. After 3 months, the MOM was 40.0 ± 2.7 mm, after 6 months—40.80 ± 4.26 mm, after 12 months—41.9 ± 4.0 mm, after more than 12 months—43.5 mm. The lowest pain intensity was observed using dermal fat taken from the iliac crest region. The rate of volumetric fat shrinkage was greater using buccal fat pad than dermis fat. Conclusions: The most commonly used types of autologous fat in interposition arthroplasty in ankylosis are the following: dermal fat from the abdominal region (iliac crest, subumbilical area, groin), buccal fat pad and full-thickness subcutaneous fat. The best results after the surgical treatment of TMJ ankylosis with interposition arthroplasty are obtained using dermis fat.
