Dental OSCE (Objective Structured Clinical Examination) Practice Exam

After dental scaling and root planing (SRP), what type of tissue is primarily formed?

1. Granulation tissue

2. A long junctional epithelium

3. Keratinized epithelium

4. Scar tissue

The correct answer is: A long junctional epithelium

After dental scaling and root planing (SRP), the primary type of tissue formed is a long junctional epithelium. This occurs as a natural part of the healing process following the removal of calculus and biofilm from tooth surfaces during SRP. The long junctional epithelium is formed when the periodontal tissue undergoes healing, providing attachment of the gingiva to the root surface. It is important because it plays a crucial role in re-establishing the periodontal attachment and acts as a barrier to bacteria, helping to maintain periodontal health. The presence of this epithelium is indicative of successful periodontal therapy and contributes to the prevention of further periodontal disease progression. In contrast, granulation tissue is typically seen in the early stages of healing after injury or infection but is not the final tissue type in this scenario. Keratinized epithelium, while beneficial, does not form directly as a result of SRP but may develop later, depending on oral hygiene and conditions. Scar tissue is produced following extensive injury and is not involved in the healing process resulting from SRP, as this procedure aims to restore health rather than create significant scarring. Thus, the formation of a long junctional epithelium highlights the
