According to the U.S. National Institutes of Health, cleft lip and/or palate (CL/P) is one of the most common congenital anomalies, significantly affecting both function and aesthetics while placing a considerable burden on healthcare systems worldwide. With the rapid advancement of artificial intelligence (AI) in various medical fields, a thorough evaluation of its role in CL/P management has become essential. Therefore, this review was undertaken to summarize recent clinical applications of AI in the diagnosis, treatment, and care of CL/P. A comprehensive search of PubMed and IEEE Xplore was conducted from January 1, 2015, to May 31, 2025, using combined keywords related to AI and CL/P. Of the 134 records initially identified, 51 full-text articles met the eligibility criteria and were included in the final analysis. In conclusion, AI is driving innovation in CL/P management across multiple domains; however, further evidence from diverse populations and the establishment of clear ethical frameworks are required to ensure its long-term clinical applicability.

Background/purpose
Large language models (LLMs), such as GPT-4o and Gemini Advanced, have performed strongly on global medical examinations. However, their capabilities in non-English, dentistry-specific licensing contexts remain unclear. Thus, this study aimed to compare the performance, consistency, and question-generation abilities of GPT-4o and Gemini Advanced in the Korean National Dental Licensing Examination (KNDLE).
Materials and methods
This study used 1,401 text-based KNDLE questions from 2019 to 2023 in Korean. Each model responded to the questions in three separate runs. Accuracy and consistency were compared with human answers. The models generated new questions in four subject areas and attempted to solve each other's generated items. Paired t-tests and chi-square tests were conducted.
Results
GPT-4o achieved significantly higher average accuracy than Gemini Advanced (81.1 % vs. 76.6 %, P = 0.013) and showed greater consistency across attempts. Both models performed better in basic sciences than in clinical subjects, such as prosthodontics. In cross-solving tasks, GPT-4o′s performance notably declined in Gemini-generated oral biology questions, indicating interpretation differences. However, the consistency difference between models was not significant (P = 0.578).
Conclusion
GPT-4o outperformed Gemini Advanced in accuracy, consistency, and alignment with its generated content. However, challenges remain in clinical domains and cross-model understanding, highlighting the potential of LLMs as supportive tools for non-English dental education and question generation while emphasizing the persistent need for expert oversight and domain-specific refinement.

Background/purpose
The patient's denture assessment (PDA) is a standardized self-reported questionnaire developed in Japan to evaluate patient satisfaction with complete dentures. Although it has been validated in multiple languages, no validated version existed for the Vietnamese population. This study aimed to assess the psychometric properties of the Vietnamese version of the PDA (PDA-V) in a clinical sample of complete denture wearers.
Materials and methods
A cross-sectional validation study was conducted with 200 complete denture wearers in a public dental hospital in Vietnam. Internal consistency was assessed using Cronbach's α. Test-retest reliability was evaluated in a subsample of 120 participants after a 7–14 day interval using intraclass correlation coefficients (ICCs). Convergent validity was examined through correlation with a 100-mm visual analog scale (VAS) of global denture satisfaction. Discriminant validity was tested by comparing PDA-V scores between patients clinically judged as needing new dentures and those who did not.
Results
The PDA-V demonstrated excellent internal consistency across all six subscales (Cronbach's α = 0.82–0.87) and strong test-retest reliability (ICC = 0.86–0.92). A significant positive correlation was found between total PDA-V and VAS satisfaction scores (ρ = 0.78, P < 0.001), supporting convergent validity. Discriminant validity was confirmed by significantly lower PDA-V scores in patients assessed as needing new dentures (P < 0.01). No significant ceiling or floor effects were observed.
Conclusion
The PDA-V is a reliable and valid instrument for evaluating patient satisfaction with complete dentures. It is suitable for both clinical assessment and research purposes in the Vietnamese population.

Background/purpose
Universal health coverage (UHC) ensures access to needed health services without financial hardship. While Taiwan has achieved near-universal coverage for most medical services, domiciliary dental care (DDC) for people with mobility limitations remains poorly integrated into the UHC framework. This study assessed DDC coverage in Taiwan using the World Health Organization UHC framework.
Materials and methods
Publicly available 2024 data were analyzed for dental institutions, practicing dentists, DDC providers, and long-term care populations across Taiwan's six National Health Insurance (NHI) regions and 22 administrative districts. Geographic distribution was examined using provider density metrics, Lorenz curves, and Gini coefficients.
Results
Among 7560 dental institutions, only 102 (1.3 %) provided DDC services, while 163 of 16,690 dentists (1.0 %) participated. Of 892,117 people who required long-term care, 23,379 (2.6 %) received DDC services. DDC represented 3.1 % of special needs dental services budget utilization. Geographic distribution demonstrated excellent equity with Gini coefficients of 0.064–0.082 and Lorenz curves above the equality line, indicating pro-rural distribution. However, service provision varied substantially: three districts had zero coverage, regional participation ranged from 0.5 % to 4.1 %, and provider density ranged from 0.7 to 3.9 per 10,000 people requiring care.
Conclusion
Despite comprehensive financial protection and equitable geographic distribution, critically low provider participation creates severe supply constraints that prevent most people requiring long-term care from accessing domiciliary oral health services. Taiwan has achieved equity in DDC distribution but not adequacy of supply, revealing substantial gaps in UHC achievement for vulnerable populations.

Cementocytes, terminally differentiated cells embedded within cellular cementum, are morphologically similar to osteocytes; however, their mechanosensory function remains poorly understood. This study aimed to investigate whether Piezo1, a mechanosensitive ion channel, contributes to the regulation of osteo/cementogenic gene expression in murine cementocyte-like IDG-CM6 cells.
Materials and methods
IDG-CM6 cells were subjected to cyclic stretch or treated with Piezo1-specific agonist Yoda1 or antagonist GsMTx4. Expression levels of osteo/cementogenic genes (Wnt1, Sost, Opg) and protein levels were analyzed. The involvement of intracellular signaling pathways was assessed using pharmacological inhibitors targeting mitogen-activated protein kinase and protein kinase B (PKB/AKT) pathways.
Results
Cyclic stretch upregulated Wnt1 and Opg, and downregulated Sost expression, without altering Piezo1 expression, suggesting an enhanced osteo/cementogenic potential. These effects were abolished by GsMTx4 and closely mimicked by Yoda1 stimulation. The Yoda1-induced gene expression changes were transient and diminished after withdrawal. Inhibitor experiments confirmed that Piezo1-mediated gene expression is modulated primarily through the AKT and p38 signaling pathways. Phosphorylation of AKT and p38 was rapidly induced by cyclic stretch.
Conclusion
Our findings demonstrate that Piezo1 functions as a mechanosensor in cementocytes, modulating the expression of osteo/cementogenic genes via the AKT and p38 pathways. This study provides new insight into the molecular mechanisms of cementocyte mechanotransduction and may inform strategies for periodontal regeneration and orthodontic treatment.

Autotransplantation (AT) is a promising alternative for restoring failed teeth. However, the success rate varies due to technique sensitivity and absence of standardized protocol. We present the first documented AT protocol utilizing a dynamic navigation system, including three core innovations: (1) navigation-guided socket preparation, (2) extra-alveolar retrograde filling, and (3) digital lingual stent fixation with flowable resin. A 55-year-old Taiwanese female with a vertical root fracture in tooth 36 underwent dynamic navigation-guided AT of tooth 38. The recipient area was prepared using a 2.5 mm wide round bur under the X-Guide® navigation. The X-Mark® probe was used to detect underprepared areas, and once preparation was deemed optimal, a three-dimensional (3D) replica was used for final confirmation. Tooth 38 was extracted and underwent retrograde filling, then transplanted into the socket of tooth 36 and fixed with a lingual stent. Postoperative image demonstrated ideal tooth positioning and favorable bone remodeling.
