Management of Precancerous Oral Lesions in Prosthetic Dentistry: A Clinical and Pathological Review

Abstract

Precancerous oral lesions, collectively referred to as oral potentially malignant disorders (OPMDs), represent a significant global health burden, particularly in developing countries like India. These lesions, including leukoplakia, erythroplakia, oral submucous fibrosis (OSMF), and lichen planus, demonstrate variable malignant transformation rates and significantly impact prosthetic rehabilitation outcomes. Prosthetic dentistry plays a crucial role not only in restoring function but also in monitoring and preventing disease progression. This review explores the clinical, pathological, and prosthetic management strategies for OPMDs, emphasizing early diagnosis, multidisciplinary intervention, and long-term surveillance. Recent advancements such as biomarker-based diagnostics, digital prosthodontics, and implant-supported rehabilitation are discussed. The integration of pathology and prosthetic considerations enhances treatment outcomes and quality of life. This review synthesizes current evidence to provide a comprehensive framework for clinicians.

Oral potentially malignant disorders (OPMDs) represent a heterogeneous group of lesions and conditions that carry a significant risk of progression to oral squamous cell carcinoma. These include leukoplakia, erythroplakia, oral submucous fibrosis (OSMF), and oral lichen planus, each characterized by distinct clinical and histopathological features. The global burden of these lesions is particularly pronounced in developing countries, where tobacco consumption, areca nut chewing, and alcohol use remain prevalent. In India, the incidence of OPMDs continues to rise, posing a substantial challenge to oral healthcare systems and necessitating early diagnosis and effective management strategies.

From a prosthodontic perspective, the presence of precancerous lesions introduces complexities in treatment planning and rehabilitation. Alterations in mucosal integrity, reduced tissue tolerance, and compromised oral function significantly influence prosthetic outcomes. Therefore, prosthetic dentistry plays a dual role—not only in restoring lost oral structures and functions but also in continuous monitoring for disease progression and recurrence.

This review aims to provide a comprehensive synthesis of the clinical presentation, pathological mechanisms, and multidisciplinary management of OPMDs, with a specific focus on prosthetic considerations. Emphasis is placed on the importance of early detection through clinical examination and adjunctive diagnostic tools such as biopsy, autofluorescence, and emerging molecular techniques. The review also highlights the role of prosthodontists in minimizing mechanical trauma, designing patient-specific prostheses, and ensuring long-term follow-up.

In addition, contemporary therapeutic approaches, including pharmacological interventions, laser therapy, and surgical excision, are critically evaluated in the context of prosthetic rehabilitation. Recent advancements such as digital prosthodontics, biomarker-based diagnostics, and artificial intelligence-assisted screening are explored as promising tools that can enhance diagnostic accuracy and treatment outcomes.

Ultimately, successful management of precancerous oral lesions requires an integrated approach involving clinicians, pathologists, and prosthodontists. By bridging clinical and pathological insights with prosthetic rehabilitation strategies, it is possible to improve patient prognosis, prevent malignant transformation, and significantly enhance quality of life. This review provides a structured framework for clinicians aiming to deliver evidence-based and patient-centered care in the management of OPMDs.
