Chronic periodontitis is the most prevalent form of periodontitis, and it generally demonstrates the characteristics of:

• A slowly progressing inflammatory disease.

• A rapid progressing inflammatory disease.

• The age of the patients.

• Vertical bone loss.

Systemic and environmental factors (eg: such as diabetes mellitus, smoking) can modify the host's immune response to dental biofilm, leading to periodontal destruction so that periodontal destruction becomes:

• More progressive.

• Less progressive.

• Healthy.

• Less progressive or healthy

Chronic periodontitis is most frequently observed:

• In children.

• In adults.

• In males.

• In females.

Chronic periodontitis has been defined as an infectious disease resulting in inflammation within:

• The gingival margin and oral mucosa.

• The papillary gingiva, rapid progress in to bone.

• Only affect in gingiva tissue.

• Progressive attachment loss, and bone loss.

A major etiologic factor that leads to periodontal destruction is:

• The composition of the oral microflora.

• The composition of saliva.

• Oral hygiene.

• The composition of saliva and Oral hygiene

Plaque accumulation on the tooth and gingival surfaces at the dentogingival junction:

• Is considered the primary initiating agent in the etiology of gingivitis and chronic periodontitis.

• Is considered the secondary agent in the etiology of gingivitis and chronic periodontitis besides diet.

• Is considered the co-factor in the etiology of gingivitis.

• Is considered the cofactor in the etiology of chronic periodontitis.

As the dental biofilm develops, early signs of an inflammatory reaction occur in the gingival margin:

• Without actual attachment loss.

• With Increased tooth mobility.

• With bone loss and attachment loss.

• With attachment loss.

In patients with early gingival inflammation, optimal plaque control leads to:

• More healthier gingival and it easy to maintain.

• Attachment loss and after that is tooth loss.

• Periodontitis in the mandibular third molar.

• The complete resolution of this early gingival inflammation.

Plaque accumulation and biofilm development:

• Are the primary causes of periodontal inflammation and destruction.

• Are the primary causes of pericoronitis.in the mandibular third molar.

• Are the primary causes of tongue diseases.

• Are the primary causes of tooth loss.in people .

Plaque accumulation and biofilm development are the primary causes of periodontal inflammation and destruction. Therefore, factors that promote plaque buildup or hinder plaque removal through oral hygiene procedures:

• Can prevent gingivitis and periodontitis

• Can prevent periodontitis and tooth loss

• Can prevent dental caries and gingivitis

• Can be detrimental to the patient
