**Question:** All are consequences of edentulism except

A. Excessive dental plaque accumulation
B. Tooth erosion
C. Tooth decay
D. Dental anxiety

**Core Concept:** Edentulism is the absence of teeth, which may lead to various oral health issues and functional problems.

**Why the Correct Answer is Right:** Dental anxiety refers to the psychological aversion to dental care and is unrelated to the physical consequences of tooth loss. It is a separate issue that could contribute to decreased adherence to dental care and further worsening of oral health.

**Why Each Wrong Option is Incorrect:**

A. Excessive dental plaque accumulation: When teeth are present, dental plaque accumulation can lead to dental caries (decay) and periodontal diseases. However, in the context of edentulism, plaque accumulation is no longer confined to tooth surfaces, leading to increased risk for periodontal diseases.

B. Tooth erosion: Tooth erosion is a consequence of tooth structure loss due to chemical processes, typically acid-induced. In contrast, edentulism results from tooth loss, not erosion.

C. Tooth decay: Dental caries (decay) is a consequence of dental plaque colonization and fermentation of carbohydrates, which are absent in edentulous patients. In contrast, tooth loss due to edentulism does not directly cause decay, but increased plaque accumulation can lead to periodontal diseases.

**Clinical Pearl:** Edentulism can lead to various oral health issues, including periodontal diseases and altered oral functions. Dental anxiety is a separate psychological issue. By understanding the consequences of tooth loss, medical and dental practitioners can provide comprehensive care for edentulous patients.
