This case report describes the successful multidisciplinary management of a large mandibular clinicoradiographic dentigerous cyst associated with two impacted permanent teeth, highlighting the potential for spontaneous tooth eruption following conservative surgical treatment. <b>Methods</b>: A healthy 14-year-old male presented with a large mandibular cyst associated with two unerupted permanent teeth. Clinical examination revealed mixed, spaced dentition with bilateral Class I molar relationships. Radiographic examination demonstrated a well-defined radiolucent lesion in the mandibular body surrounding the crown of an impacted first premolar and displacing the adjacent permanent canine. As no histopathological examination was performed, the diagnosis was established on clinical and radiographic grounds. Treatment objectives were to resolve the cystic lesion, promote spontaneous eruption of the impacted teeth, achieve alveolar bone regeneration and resolve the associated malocclusion.

This scoping review maps global evidence on AI for periodontal diagnosis, risk prediction, and monitoring; evaluates governance frameworks; and proposes a contextualised implementation model for emerging health systems. <b>Methods:</b> Following PRISMA-ScR and PRISMA 2020 guidance, PubMed/MEDLINE, Scopus, Web of Science, Embase, and Cochrane Library were searched (January 2015-April 2025), supplemented by regulatory and grey literature; ten additional sources published after the search closure were subsequently identified through citation checking and expert peer review during revision, as a targeted amendment rather than a re-executed database search.

In contrast, panoramic radiographs are widely available and increasingly amenable to automated analysis through artificial intelligence (AI). Recent AI systems have demonstrated high accuracy in the detection and quantification of periodontal bone loss and in radiographic disease staging. &lt;b&gt;Objective:&lt;/b&gt; To review current evidence on AI applications in periodontal radiology and explore whether routinely acquired panoramic radiographs may support the development of AI-assisted radiographic periodontal charting. &lt;b&gt;Methods:&lt;/b&gt; This narrative review summarizes recent evidence regarding AI-based periodontal and peri-implant radiographic assessment. The literature was identified through searches of PubMed, Scopus, and Google Scholar using combinations of terms related to artificial intelligence, periodontal disease, radiographic diagnosis, panoramic radiography, and peri-implantitis, with emphasis on studies relevant to AI-assisted periodontal assessment. &lt;b&gt;Results:&lt;/b&gt; Recent deep learning architectures have demonstrated high diagnostic performance for periodontal bone loss detection, quantification, and disease staging. Current AI systems are capable of identifying radiographic manifestations of periodontal destruction and localising key anatomical landmarks, including the cemento-enamel junction and the alveolar bone crest. However, they remain unable to assess clinical parameters such as probing depth, bleeding on probing, suppuration, and tooth mobility. The review highlights the distinction between Clinical Attachment Level (CAL), Clinical Attachment Loss (CALoss), and radiographic measures of periodontal destruction. In this context, the concept of Radiographic Attachment Loss (RAL) is proposed as the radiographically measurable distance between the cemento-enamel junction and the alveolar bone crest, providing a conceptual estimate of periodontal support loss. &lt;b&gt;Discussion:&lt;/b&gt; The principal novelty of this review is the proposal of AI-assisted radiographic periodontal charting as a clinically oriented framework for translating AI-derived radiographic information into meaningful periodontal assessment. Rather than replacing conventional periodontal charting, this approach aims to transform routinely acquired panoramic radiographs into a source of structured periodontal information that may support screening, risk stratification, longitudinal monitoring, and clinical decision-making. &lt;b&gt;Conclusions:&lt;/b&gt; Artificial intelligence is unlikely to replace conventional periodontal examination.
