National Board Dental Hygiene Examination Part B - FAQ Sample Questions

What is the rationale for exposure of vertical bitewings for this patient? 





Correct Answer:
better evaluate periodontal structures


the rationale for employing vertical bitewings in dental imaging, particularly for this patient, centers on their efficacy in evaluating the periodontal structures more comprehensively compared to horizontal bitewings. vertical bitewings are particularly advantageous in visualizing the bone levels around the teeth, which is crucial for diagnosing and managing periodontal disease.

in contrast to horizontal bitewings, which are primarily used to detect interproximal caries and are limited to showing only a portion of the alveolar bone, vertical bitewings provide a more extended view of the bone and the periodontal status. this is particularly important in patients who are suspected of having periodontal issues or have clinical signs of gum disease. the vertical orientation allows the radiograph to capture more of the jawbone, thus helping in assessing bone loss, the configuration of bone defects, and other details pertinent to periodontal assessment.

additionally, vertical bitewings can be used to evaluate the presence and severity of periodontal disease by showing changes in bone height, the architecture of the alveolar crest, and other critical factors like the presence of calculus which might not be as clearly visible in horizontal bitewings. these details are essential for planning appropriate periodontal treatments and for monitoring the progression of periodontal disease.

while periapical radiographs are also vital in dental diagnostics, their primary focus is on identifying periapical pathology such as abscesses or cysts, and they do not provide as broad a view of the periodontal bone status as vertical bitewings. hence, when a comprehensive assessment of the periodontal structures is required, vertical bitewings are preferred.

in summary, the use of vertical bitewings in this patient's case is justified by the need for a detailed examination of the periodontal structures to better diagnose, treat, and manage periodontal disease. their ability to provide a more extensive view of the bone surrounding the teeth makes them an invaluable tool in periodontal assessment.

During the intraoral examination, the clinician notes symmetrical bone loss at the first molars and incisors.  The patient's oral hygiene is evident of effective plaque removal.  Based on the evidence of bone loss around the first molars and incisors, this adolescent patient probably has which oft he following periodontal diseases or condition? 





Correct Answer:
aggressive periodontits
aggressive periodontitis is a unique and severe form of periodontal disease that typically affects adolescents and young adults, though it can occasionally occur in older individuals. this condition is distinguished from other periodontal diseases primarily by the rapid rate of bone loss and the specific pattern of periodontal destruction, particularly affecting the first molars and incisors.

the hallmark of aggressive periodontitis is the significant amount of bone loss around the teeth that occurs at a much faster rate compared to what is observed in chronic periodontitis. in aggressive periodontitis, despite the presence of good oral hygiene practices and minimal plaque accumulation, patients still experience severe and rapid periodontal destruction. this suggests a possible underlying systemic or genetic predisposition that contributes to the aggressive nature of the disease.

one of the key characteristics of aggressive periodontitis is its familial aggregation, indicating a genetic component to the disease. it has been associated with alterations in the immune response, particularly defects in neutrophil function. neutrophils are a type of white blood cell important for fighting infections, including those caused by the bacteria that colonize the mouth and can lead to periodontal disease.

clinically, aggressive periodontitis may present with pocket formation and gum recession around the affected teeth, leading to mobility and, if untreated, eventual tooth loss. the pattern of bone loss in aggressive periodontitis—frequently affecting the first molars and incisors—is another distinguishing feature. this pattern can be detected through radiographic examination, which typically shows vertical bone loss around these teeth.

diagnosis and management of aggressive periodontitis require a comprehensive approach. a detailed medical and family history can provide clues about the underlying systemic factors and genetic predisposition. periodontal examination and radiographs are essential to assess the extent and pattern of bone loss. management often involves a combination of mechanical debridement, antimicrobial therapy, and possibly surgical intervention, along with close monitoring and maintenance.

in conclusion, the diagnosis of aggressive periodontitis in an adolescent with effective plaque control but evident symmetrical bone loss around the first molars and incisors is based on the characteristic rapid progression of the disease, the specific pattern of bone loss, and the potential underlying genetic factors that contribute to this severe form of periodontal disease. early diagnosis and aggressive treatment are crucial to manage this condition effectively and preserve the dentition.
