Mrs. Wilson, a 45-year-old woman, visits your dental clinic for her first check-up and cleaning after her long-term dentist of 20 years recently retired. She reports that her previous dentist only performed light cleanings and did not provide specific instructions regarding her periodontal health. Mrs. Wilson has a clear medical history but mentions smoking 11 cigarettes a day for over 25 years and a family history of early tooth loss. She admits to brushing her teeth once daily with a manual toothbrush but does not floss regularly. She is unaware of any gum problems, as she has not experienced pain or noticeable changes, except for occasional bleeding when brushing. As a newly registered dentist, Dr. Stevens conducts a thorough periodontal examination, noting heavy plaque and calculus deposits, generalized probing depths of 5–6 mm, and recession of up to 2 mm on the lower anterior teeth. Bleeding on probing is observed in multiple areas. Mrs. Wilson provides an orthopantomogram (OPG) from her last dental visit, which reveals moderate alveolar bone loss consistent with chronic periodontitis. During the consultation, Mrs. Wilson expresses surprise at the findings and questions how her periodontal condition developed despite being under regular care. She inquires if her previous dentist failed to diagnose her condition and whether she should take legal action. Additionally, Mrs. Wilson seems reluctant to believe smoking could significantly impact her oral health. Amid these discussions, Dr. Stevens accidentally touches a sterile instrument with gloved hands after contacting Mrs. Wilson’s mouth. Recognizing the breach, she must make an immediate decision while maintaining patient safety and professional integrity. Later in the day, a sterilization failure is detected in the practice autoclave, and Dr. Stevens must navigate infection control protocols to address potential patient risks and manage the situation appropriately.

David Smith, a 54-year-old high school teacher, presented to your clinic with a history of trauma to the maxillary left canine (tooth 23) sustained during a minor accident two weeks ago. He has a medical history of type 2 diabetes (HbA1c = 7.8%) and hypertension (controlled with medication: amlodipine 5mg daily). The tooth showed clinical signs of pulp necrosis, which were confirmed radiographically and by pulp vitality tests. After thorough discussions, you advised root canal treatment (RCT) followed by a full coverage restoration to restore function and esthetics.

You discussed multiple crown options, including metal ceramic, porcelain fused to metal (PFM), and full porcelain crowns. After considering esthetics, durability, and cost, David expressed satisfaction with the porcelain fused to metal crown.

Treatment Plan:

• Completion of RCT on tooth 23.
• Preparation of tooth 23 for a PFM crown.
• Fabrication of provisional crown to protect the prepared tooth.
• Final cementation of the PFM crown after successful trial fitting.
