Periodontium Components and Diseases Quiz

Which of the following are components of the periodontium?

A normal, intact periodontium will always show bone loss in furcation areas.

What is the average distance, in millimeters, between the cementoenamel junction (CEJ) and the alveolar bone crest (AC) in a healthy individual?

The inter-dental crestal bone is not directly connected to the lamina dura of adjacent teeth.

Periodontal diseases are a set of conditions characterized by an inflammatory host response that primarily affects the hard tissues around the teeth.

Once periodontitis has developed, alveolar bone loss can be reversed without intervention.

Radiographs can solely determine the presence of clinical periodontal health on a reduced periodontium.

Which of the following clinical examinations can be used to assess the extent of periodontal disease?

2D radiographs can provide a complete view of the bucco-lingual aspects of the interproximal bone.

Incorporating digital image receivers, such as phosphor storage plates or solid-state detectors, is not necessary for minimizing radiation exposure.

For patients with generalized periodontal pockets measuring less than 5 mm in depth, bitewing radiographs are not recommended.

The bisecting-angle technique for acquiring periapical radiographs is preferred over the paralleling technique due to its superior geometric configuration.

Panoramic radiography is not a low-dose radiation technique.

What is the major limitation of panoramic radiography that affects the reliability of linear measurements?

The upward angulation of the X-ray beam used in panoramic radiography can cause horizontal overlap and distortion, making it difficult to visualize fine structures like the periodontal ligament space.

What are the primary limitations of 2D radiographs in periodontal diagnosis?

Early periodontal lesions are easily diagnosed accurately using radiographic imaging.

Radiographic images provide valuable information regarding the detection of periodontal pockets and tooth mobility, crucial aspects for periodontal diagnosis.

Changes in the internal aspect of the alveolar bone can only reflect a reduction in bone structure/trabeculation.

Horizontal bone loss is the most common pattern of bone loss in periodontal disease.

Vertical bone loss occurs solely due to a lack of horizontal bone loss.

Vertical bone loss always appears as three walled defects.

It is always possible to recognize vertical defects on a radiograph.

Periodontal furcation bone loss occurs only in single-rooted teeth.

Peri-implant health is characterized by the absence of visual signs of inflammation and bleeding on gentle probing.

Peri-implant diseases are classified as either peri-implant mucositis or peri-implantitis, but not both.

Peri-implant mucositis is an inflammatory condition that involves the loss of bone around the dental implant.

Peri-implant mucositis is irreversible and cannot be treated.

The thickness of keratinized mucosa around dental implants does not play a role in the development of peri-implant mucositis.

Periodontal abscesses are always associated with pain and tenderness in the gingiva.

The most common finding in a periodontal abscess is a suppurative discharge on probing or sampling.

Radiographically, periodontal abscesses typically appear well-defined around the root of the affected tooth.

Endodontic and periodontal lesions are always distinct and never overlap.

The presence of a sinus tract is always a sign of an endodontic lesion.

Radiographs are the primary method for diagnosing endodontic and periodontal lesions.

What are the four components of the periodontium?

A normal, intact periodontium should show evidence of bone loss in furcation areas.

What is the average distance, in millimeters, from the most coronal portion of the alveolar bone crest (AC) to the cementoenamel junction (CEJ) in a healthy individual?

The inter-dental crestal bone is continuous with the lamina dura of the adjacent teeth in a healthy periodontium.

What is the name of the inflammatory host response that characterizes periodontal diseases?

Clinical periodontal health can be determined using radiographs alone.

Which of these is NOT a clinical examination technique used in the assessment of periodontal conditions?

What type of radiographs help in evaluating the extent of bone loss around teeth, crucial for diagnosing the severity of periodontal disease?

Which of these is NOT a benefit of using digital radiography in periodontal assessment?

Which type of radiograph is considered most commonly used for assessing generalized periodontal pockets measuring < 5 mm in depth?

The paralleling technique for acquiring periapical radiographs is generally considered less accurate than the bisecting-angle technique.

What is the main advantage of using panoramic radiographs for periodontal assessment?

Panoramic radiography is the preferred imaging modality for periodontal assessment, especially when complemented with intraoral radiographs.

Which of the following is a limitation of using 2D projections for periodontal assessment?

Radiographic assessment can provide a complete view of the bucco-lingual aspects of the interproximal bone.

Radiographic images are always reliable in accurately assessing early stages of periodontal disease.

Which of these is NOT a limitation of radiographs, as they relate to periodontal diagnosis?

Which of the following is an initial radiographic change seen in periodontitis?

In severe cases of periodontal disease, the posterior regions of the alveolar bone crest may appear rounded off with an irregular and diffuse border between the lamina dura and alveolar crest.

Changes to the internal aspect of the alveolar bone can reflect which of these conditions? (Select all that apply)

What is the most common pattern of bone loss in periodontal disease?

Vertical bone loss indicates the presence of vertical or angular osseous defects.

What is the term used to describe a vertical defect that is surrounded by three bony walls?

Vertical defects are always easily recognizable on a radiograph.

What type of bone loss occurs in the furcation area of multi-rooted teeth?

Match the grade of furcation involvement with its description:

Peri-implant diseases are broadly divided into which two categories?

Peri-implant mucositis is a reversible condition.

What is the minimum thickness of keratinized mucosa that may contribute to the development of peri-implant mucositis?

Peri-implant mucositis is primarily caused by plaque-associated inflammation.

Which of the following is NOT a potential cause of peri-implant mucositis?

What are the common clinical features of a periodontal abscess? (Select all that apply)

What is a common clinical finding associated with periodontal abscesses?

Which of the following can contribute to the formation of a periodontal abscess? (Select all that apply)

Severe anatomic alterations, such as invaginated teeth or dens evaginatus, can contribute to the formation of periodontal abscesses.

Vertical root fractures or cracked tooth syndrome extending through the root can lead to periodontal abscesses.

What is the radiographic appearance of a periodontal abscess?

Match the type of lesion with its corresponding radiographic finding for periodontal disease:
