A narrative literature search was conducted across PubMed/MEDLINE, Scopus, EMBASE, the Cochrane Library, and Google Scholar using the terms \"finite element analysis,\" \"FEA,\" \"dental biomechanics,\" and \"stress distribution,\" combined with specialty-specific MeSH headings. Articles published in English from 1969 to June 2026 were considered. Inclusion criteria were primary FEA research articles, systematic reviews, and authoritative biomechanics textbooks. Exclusion criteria were non-English language publications, conference abstracts without full-text availability, and studies involving non-dental anatomical sites exclusively. No formal PRISMA-based systematic process was applied, consistent with the narrative review format; this review was not prospectively registered. FEA has demonstrated substantial methodological utility as a hypothesis-generating and design-optimisation tool across implantology, orthodontics, endodontics, prosthodontics, periodontics, oral and maxillofacial surgery, restorative dentistry, paediatric dentistry, and temporomandibular joint disorders; however, much of the available literature remains computational and hypothesis-generating rather than clinically validated. Key applications include peri-implant stress distribution modelling, orthodontic force optimisation, endodontic instrument fatigue prediction, and prosthetic material selection. Persistent limitations include oversimplification of biological tissue properties, absence of validated dynamic loading models, and lack of inter-study standardisation. The quality of FEA outputs is critically dependent on the accuracy of geometry reconstruction, the completeness of material property assignment, the realism of loading conditions, and the presence of experimental model validation.

Three patients presenting with deep carious lesions and signs consistent with reversible pulpitis were treated under rubber dam isolation, involving a total of four posterior teeth. Direct pulp capping was performed in two patients, respectively in a mandibular premolar (Case 1) and a mandibular first molar (Case 2) after pulp exposure during caries removal, whereas indirect pulp capping was performed in two mandibular molars of the same patient (Case 3) affected by deep carious lesions.

In the direct pulp capping cases, treatment was completed in a single visit with immediate adhesive composite restoration using a 10-MDP-based universal adhesive.
