Case #2 Scenario: A 63-year-old female presented with the chief complaint: “My teeth are shaking and I feel they are going to come out.” Dental history: she had a removable partial denture that had just fractured. The implant in site #3 was placed more than 10 years earlier, but had never been restored (see radiograph below ). Findings: generalized widening of the periodontal ligament with mobility (grade 2 and 3). Generalized mild horizontal bone loss. Generalized probing depths of 1 to 3mm with bleeding on probing in less than 10% of the sites. This patient will most benefit from which of the following procedures?

Which of the following statements describes the “ostectomy” procedure? 

Your patient presents to her routine periodontal maintenance visit with a new CC of “loose teeth”. She is classified as “health on a reduced periodontium” with a history of Stage III, Grade C periodontitis, associated with periodontal disease. She states she has been clenching and grinding lately, and feels like her teeth are moving.   How would you classify her present condition?  

Which of the following may be a risk for a mandibular molar with a short root trunk when evaluating the tooth for osseous surgery?

Case #1:  Scenario: An 18-year-old female presented with the chief complaint: “I want my smile back. I was in an accident and lost my front teeth”. She reported no  medical conditions.  Dental history: clinical health with no significant probing depths, bleeding on probing, or mobility. The treatment plan for implants from #6–11 was generated in collaboration with the restoring dentist. In order to address the malalignment on the mandibular arch, an orthodontist was consulted after the tooth vitality was confirmed by an endodontist. Once confirmed, a combination of bone grafting materials was used on the maxillary ridge.     In the case above, the periodontist opted for bone grafting material from a cadaver bone. This is called a(n):

A furcation with gingival coverage and extensive bone destruction that permits probing into, but not through the furcation area, would most likely be classified as a Glickman:

Removing buccal exostoses would require which type of flap classification? 

Which of the following statements accurately reflects the relationship between occlusal trauma and periodontitis?

Which of the following statements best describes the differences between 1-wall, 2-wall, and 3-wall periodontal bone defects?

Case #3 Scenario: A 49-year-old male patient had been seen earlier by his general dentist and was later referred to a periodontist for evaluation. When he presented to the initial evaluation, his chief complaint was “I have tenderness in the upper front gum area and it bleeds when I brush.” The patient is medically healthy and takes Aspirin occasionally for headaches.  The crowns in the maxillary central incisors had been delivered 3 months earlier. Periodontal exam revealed dental plaque–induced gingivitis and gingival (pseudo) pockets in the maxillary anterior sextant with 100% bleeding on probing in this sextant. Radiographic exam revealed normal bone levels throughout the dentition. It was clear that the margins of these crowns were more subgingival than the desired location, and accumulating plaque.   Which of the following is a probable cause for the gingival condition observed in relation to the maxillary central incisors?
