#1. Which of the following bacteria is most strongly associated with the pathogenesis of chronic periodontitis?

Streptococcus mutans

Porphyromonas gingivalis

Fusobacterium nucleatum

Streptococcus pneumoniae

Actinomyces viscosus

#2. The initial phase of periodontal disease involves the accumulation of biofilm. Which of the following immune responses is typically the first to occur in response to bacterial plaque accumulation?

Adaptive immune response

Neutrophil infiltration

Lymphocyte infiltration

Bone resorption

Formation of granulomas

#3. Which of the following cytokines plays a critical role in the inflammatory response and is elevated in periodontal disease, contributing to tissue destruction?

Interleukin-1 (IL-1)

Interferon-gamma (IFN-γ)

Tumor necrosis factor-alpha (TNF-α)

Interleukin-4 (IL-4)

Interleukin-10 (IL-10)

#4. What is the primary role of Porphyromonas gingivalis in the pathogenesis of periodontitis?

Producing a high number of spores

Inducing an immune evasion response

Triggering bone formation

Contributing to tooth enamel remineralisation

Increasing salivary flow

#5. The formation of periodontal pockets is primarily a result of:

Increased salivary flow

Inflammatory responses leading to tissue breakdown

Direct bacterial invasion into the alveolar bone

Normal aging processes

Salivary enzyme secretion

#6. Which of the following is a characteristic feature of Molar-Incisor (formerly Aggressive) periodontitis?

High prevalence of Streptococcus mutans

Presence of high levels of Porphyromonas gingivalis

Onset at a young age with rapid attachment loss

Association with systemic conditions like diabetes

Slow progression of disease over decades

#7. Which immune cells are primarily involved in the resolution of periodontal inflammation?

Neutrophils

Mast cells

T regulatory cells

B lymphocytes

Plasma cells

#8. In periodontal disease, bone loss is often associated with the increased production of which of the following molecules?

Osteoprotegerin

Receptor activator of nuclear factor kappa-B ligand (RANKL)

Interleukin-4 (IL-4)

Platelet-derived growth factor (PDGF)

Transforming growth factor-beta (TGF-β)

#9. Which of the following is NOT considered a risk factor for the development and progression of periodontal disease?

Smoking

Poor oral hygiene

Genetic predisposition

Controlled diabetes

Stress

#10. Which of the following factors contributes to the disruption of the host-parasite balance in periodontal disease?

Regular biofim removal

The immune system’s failure to control pathogenic bacteria

Increased salivation

The presence of fluoride in water

Maintenance of a healthy oral microbiome
