National Board Dental Hygiene Examination Part B - Why Exam Edge Sample Questions

Since the patients last visit 6 years ago, his periodontal status has changed from gingivigis to periodontitis.  Which of the following is the MAIN reason for the difference in the diagnosis? 

Correct Answer:
clinical attachment loss
to fully comprehend why "clinical attachment loss" is considered the primary reason for the change in diagnosis from gingivitis to periodontitis, it is essential to understand the definitions and implications of both terms, as well as the meaning of clinical attachment loss.

gingivitis is the inflammation of the gums (gingiva) and is characterized primarily by redness, swelling, and bleeding upon probing. it is a non-destructive form of periodontal disease, meaning that it does not involve the loss of bone or connective tissue around the teeth. gingivitis is usually reversible with good oral hygiene.

periodontitis, on the other hand, is a serious gum infection that damages the soft tissue and, without intervention, can destroy the bone that supports your teeth. periodontitis can cause teeth to loosen or lead to tooth loss. periodontitis is primarily distinguished from gingivitis by the level of attachment loss.

clinical attachment loss refers to the destruction of the supporting tissues around the teeth, including both gum tissue and bone. it is measured from the cemento-enamel junction (the point where the enamel of the tooth meets the cementum covering the root) to the base of the periodontal pocket (the deepened gap between the gum and the tooth root caused by periodontal disease). as periodontitis progresses, more of the tooth's support structure is lost, increasing the depth of the periodontal pockets and worsening the clinical attachment loss.

while other factors such as bleeding on probing, an increase in plaque, and an increase in calculus are significant indicators of periodontal health, they are more reflective of inflammation and hygiene status rather than the actual destruction of tissue, which is the hallmark of periodontitis. bleeding on probing might still be observed in gingivitis without any attachment loss. similarly, increases in plaque and calculus can contribute to the development of periodontitis but are not direct measures of tissue destruction.

therefore, the diagnosis of periodontitis over gingivitis primarily hinges on the evidence of clinical attachment loss, as it directly reflects the irreversible damage to the tissues that support the teeth. this makes it the main reason for changing the diagnosis from gingivitis to periodontitis when observed in a patient's dental assessment.

This patient notes to you that he is concerned with his HIV status and his oral health and he asks if chlorohexidine could be used safely as a mouthrinse at home. Which of the following is NOT a side effect that the clinician should educate the patient about? 

Correct Answer:
increase in subgingival calculus formation
when considering the use of chlorhexidine as a mouthrinse, it is essential to be aware of its possible side effects. chlorhexidine is a widely used antimicrobial agent that helps in reducing dental plaque and gingivitis, but it also comes with certain drawbacks that patients should be educated about.

one notable side effect of chlorhexidine is the staining of teeth. this occurs because chlorhexidine can bind to dietary factors and other substances in the mouth, leading to noticeable discoloration on the surface of the teeth. this side effect is more pronounced with long-term use and can be somewhat managed through regular professional cleaning and careful oral hygiene practices.

another side effect is the increase in supragingival calculus formation. chlorhexidine has been shown to promote the mineralization of dental plaque into calculus, particularly above the gum line (supragingival). this can lead to a rougher surface on teeth which may require professional cleaning to remove. it is important to note that this side effect pertains to supragingival (above the gum line) calculus and not subgingival (below the gum line) calculus formation.

taste alteration is also a common side effect reported by users of chlorhexidine mouthrinse. some patients may experience a change in their taste perception, typically a metallic or bitter taste, which can impact their enjoyment of foods and drinks. this side effect is usually temporary and diminishes once the use of the mouthrinse is discontinued.

additionally, some individuals might experience a mild burning sensation in the mouth when using chlorhexidine. this can vary from person to person in intensity and can be uncomfortable, especially with higher concentrations of chlorhexidine or prolonged use.

to address the question, it is critical to clarify that while chlorhexidine contributes to an increase in supragingival calculus formation, it does not specifically cause an increase in subgingival calculus formation. this distinction is crucial for accurate patient education and managing expectations regarding the use of chlorhexidine mouthrinse. therefore, when discussing the side effects with a patient concerned about their oral health, particularly in relation to hiv status where meticulous oral hygiene is even more significant, it is important to emphasize the correct side effects associated with its use.
