School of Dentistry Faculty Research and Publications

Background

To develop a no-code artificial intelligence (AI) model for the detection of apical radiolucent lesions and to assess how lesion location influences the model’s diagnostic performance.

Methods

312 periapical radiographs were retrospectively collected, each accompanied by a corresponding cone-beam computed tomography (CBCT) scan obtained within six months and a radiology report authored by board-certified oral and maxillofacial radiologists. These reports served as the reference standard, and all findings were cross-verified by the primary investigator through CBCT review. The dataset included 181 images with at least one apical radiolucent lesion and 131 lesion-free controls. Using the no-code AI platform LandingLens …

Evaluation Of Enamel Demineralization Around Bonded Lingual Retainers Cured Using The Transillumination Technique: An In Vitro Sem Study, Monis Raza, Achint Juneja, Udit Chaudhary, Anju Treesa Jacob, Vikas Thakur, Aayush Sudan

International Arab Journal of Dentistry

Introduction: Polymerization technique may influence enamel demineralization around bonded lingual retainers by affecting adhesive integrity.

Methods: Eighty-four mandibular incisors were randomly allocated to conventional curing (30 s), transillumination (30 s), or combined curing (15 s each). Specimens underwent pH cycling and were evaluated using scanning electron microscopy. Demineralization was scored (0–3), and linear lesion depth was measured. Data were analyzed using Kruskal–Wallis, Bonferroni, and Mann–Whitney tests (p ≤ 0.05).

Results: Combined curing significantly reduced demineralization compared with conventional and transillumination protocols (p < 0.001). Gingival regions showed significantly greater demineralization than occlusal regions across all groups.

Conclusions: Combined curing improved enamel preservation and may be an effective strategy for bonded …

Stem Cell-Based Therapies In Periodontology And Implant Dentistry: A Systematic Review And Meta-Analysis, Abdullah Saeed, Marycris Padrigo

International Arab Journal of Dentistry

Introduction: Periodontal disease and peri-implantitis remain the leading causes of tooth and implant loss, and conventional regenerative procedures consistently fall short of full structural restoration. Stem cell therapies have emerged as a promising alternative, operating through multi-lineage differentiation, immunomodulation via paracrine signaling, and extracellular vesicle communication. Prior systematic reviews, however, lacked methodological rigor — omitting clustering adjustments, REML/HKSJ estimation, prediction intervals, and publication bias modeling.

Aim: This systematic review and meta-analysis evaluated whether stem cell therapy produces superior clinical and radiographic outcomes compared to cell-free controls in adults with periodontal or peri-implant bone defects.

Methods: Searches across …
