Question 1

Pathologic mobility is tooth displacement that occurs when the balance among the factors that maintain physiologic tooth position is disturbed.The teeth can move in any direction; when they move in the occlusal direction,it is known as extrusion or elongation.

Accepted Answer

The answer of Pathologic mobility is tooth displacement that occurs...

Question 2

Which of the following descriptions is correct,based on the four universally accepted descriptive categories?

Accepted Answer

The answer of Which of the following descriptions is correct,based...

Question 3

Digital subtraction radiography (DSR)is being used in the diagnosis of periodontal disease and bone regeneration.Two exposures are taken at different intervals,and the changes in bone density that occurred during the interval are measured.

Accepted Answer

Digital subtraction radiography (DSR) is indeed used in the diagnosis of periodontal disease and bone regeneration by taking two exposures at different intervals to measure changes in bone density, making both statements true.

Question 4

Which of the following teeth may have a bifurcated root?

Accepted Answer

The maxillary first premolar often has two roots, making it the most likely among the options to have a bifurcated root.

Question 5

PSR is the abbreviation for:

Accepted Answer

PSR stands for "Periodontal screening and recording" which is a simple and effective way to assess a patient's periodontal health by examining six specific areas of the mouth.

Question 6

Which of the following is an example of a physiologic cause of tooth mobility?

Accepted Answer

Normal tooth movement is a physiological cause of tooth mobility, as teeth can have slight natural movement within their sockets.

Question 7

What provides the most reliable and accurate means of assessing the progression and remission of periodontal disease?

Accepted Answer

CAL (clinical attachment level) provides the most reliable and accurate means of assessing the progression and remission of periodontal disease. It measures the distance from the CEJ (cementoenamel junction) to the bottom of the pocket, taking into account the amount of gingival recession. This measurement reflects the amount of supporting tissue loss and is a better indicator of disease progression than pocket depth alone.

Question 8

Nonkeratinized,loosely attached,and movable tissue that begins at the mucogingival junction is:

Accepted Answer

The alveolar mucosa is the correct answer because it is the nonkeratinized, loosely attached, and movable tissue that begins at the mucogingival junction, distinguishing it from the attached gingiva, which is keratinized and tightly adherent to the underlying bone.

Question 9

Recession is the distance between the:

Accepted Answer

Recession is defined as the displacement of the gingival margin apical to the cemento-enamel junction (CEJ), thus the distance between the CEJ and the gingival margin accurately describes recession.

Question 10

Which assessment tool provides a numerical reading of the depth of the epithelial attachment in relation to the CEJ and the gingival margin?

Accepted Answer

Probing measurements are the only tool mentioned that provide a numerical reading of the attachment depth. Radiographic images can show bone level but do not directly measure attachment depth. Autofluorescence imaging, spectro-optical scanning, and fiberoptic endoscopy are not mentioned as tools for measuring attachment depth.

Question 11

Which is the correct order for the dental hygiene process of patient care?

Accepted Answer

The correct order for the dental hygiene process of patient care is assessment, diagnosis, planning, implementation, and evaluation. This sequence allows the dental hygienist to gather information about the patient's oral health, make a diagnosis, plan appropriate interventions, implement those interventions, and then evaluate the outcomes to determine if further care is needed.

Question 12

Inflammation of the soft tissue around an implant is _________________.

Accepted Answer

The answer of Inflammation of the soft tissue around an...

Question 13

Which of the following may not be a sign of peri-implantitis or a sign that an implant is failing?

Accepted Answer

Smooth, red gingival tissue around the implant may signify inflammation, but it is not enough on its own to determine if the implant is failing or if peri-implantitis is present. Other signs such as pocket depth, bleeding on probing, visible exudate, and detectable mobility are more indicative of peri-implantitis or implant failure.

Question 14

Which color of gingival tissue indicates chronic inflammation?

Accepted Answer

Dark red to cyanotic gingival tissue indicates chronic inflammation due to the increased blood flow and accumulation of inflammatory cells in the area. Bright red gingival tissue may indicate acute inflammation, pale coral pink is the normal color of healthy gingiva, and brown may indicate melanin pigmentation.

Question 15

Implants should be probed to assess the health of an implant site.A healthy probing depth for an implant is:

Accepted Answer

Healthy probing depths for dental implants typically range from 3 to 4 mm, similar to natural teeth, indicating that the surrounding tissues are healthy and not inflamed.

Question 16

Brown stain

Accepted Answer

The description matches that of a brown stain caused by tannin, which is the most common stain associated with poor oral hygiene.

Question 17

The col is the depression between the buccal and lingual papilla of two adjacent teeth.It is made of keratinized tissue and conforms to the interproximal contact area.

Accepted Answer

The first statement is true as the col is the depression between two adjacent teeth that is keratinized and conforms to the interproximal contact area. The second statement is false as the col is not made of connective tissue.

Question 18

A pigmented deposit on a tooth surface is:

Accepted Answer

A pigmented deposit on a tooth surface that can be removed by polishing is an extrinsic stain. Intrinsic stain refers to discoloration within the tooth structure, calculus is hardened dental plaque that requires professional removal, and plaque biofilm is a sticky bacterial accumulation on tooth surfaces.

Question 19

Gingiva that appears shiny and smooth with no stippling and has rolled margins is:

Accepted Answer

Gingiva that appears shiny and smooth with no stippling and has rolled margins is a sign of inflammation, commonly seen in cases of gingivitis. This is due to the increased vascularity of the gingiva, which causes it to lose its characteristic stippling and become smooth and shiny. The rolled margins are a result of the swelling and enlargement of the gingiva. Therefore, the correct answer is B, inflamed. The other options are not accurate as healthy gingiva would display characteristic stippling, fibrotic gingiva would be tough and leathery, and changes in gingival characteristics are not necessarily age-related.

Question 20

Pathologic tooth migration occurs most often in:

Accepted Answer

Pathologic tooth migration is commonly seen in maxillary anterior teeth due to the presence of muscular forces in the area coupled with insufficient interdental bone support. This can result in the teeth drifting out of their normal position.
