OSF showed significant changes in affected gingiva, and the presence of comet cells in all the patients with OSF is a significant indicator of possible pathognomonic developments.

Research in the field of periodontology has witnessed a tremendous upsurge in the last two decades unveiling newer innovations in techniques, methodologies, and material science. The recent focus in periodontal research is an evidence-based approach which offers a bridge from science to clinical practice. This three part review series intends to take a reader through a maze of periodontal research, unraveling and simplifying various issues in the design, conduct and interpretation of various study designs routinely used in the field of periodontal research. This understanding would facilitate a researcher with a focused and an enhanced vision toward formulating studies which can more efficiently translate sound scientific phenomena into clinically meaningful results.
