Final answer:
The statement is false because successful periodontal debridement does not require the complete removal of all cementum, which is crucial for tooth stability.
Step-by-step explanation:
The correct answer is option B. False. Successful periodontal debridement does not necessarily result in the complete removal of all cementum. Periodontal debridement aims to eliminate pathogenic bacteria and calculus from the tooth surfaces and beneath the gingival margin.
While some removal of the cementum may occur to ensure that the root surface is clean and free of bacteria, normal debridement procedures seek to preserve the cementum as much as possible.
Cementum is an important tissue that helps to anchor the teeth to the surrounding structures within the jaw through the periodontal ligament. Maintaining healthy cementum is crucial for the stability of teeth, especially after periodontal disease has caused some loss of the surrounding alveolar bone and periodontal ligament attachment.
Successful periodontal debridement does not always result in the complete removal of all cementum from a root surface exposed due to clinical attachment loss.
Periodontitis is a condition characterized by the receding gums and exposure of parts of the tooth that are normally covered. In severe cases of periodontitis, the infection can spread to the ligaments and bone tissue supporting the teeth, leading to tooth loss or the need for surgical removal.
