ABSTRACT: Replacement of a single anterior tooth in the aesthetic zone while planning for future implant placement is crucial to the restorative treatment plan. Several methods exist for immediate provisionalisation of the extracted tooth while waiting for soft and hard tissue healing. Although there's a myriad of possible provisionalisation methods available, each option has its advantages and disadvantages. The treatment options should weigh various factors such as the available materials, ease of fabrication, costs, and the effect on the future implant site. This article describes three clinical cases demonstrating a simple yet cost-effective technique to temporarily replace an extracted single anterior tooth, enhancing patient satisfaction and increasing compliance before receiving the definitive implant restoration. The pro and cons for each treatment option available as opposed to the technique involved in the three cases used are also described.

ABSTRACT: Pseudo-infarction ECG pattern resembling "Shark Fin" was demonstrated in a 76-year-old lady with a previous total thyroidectomy who presented with unspecific symptoms. An incidental finding of hypokalemia and hypocalcemia was thought to be related to delayed onset hypoparathyroidism. Potential etiologies like coronary vasospasm and catecholamine-associated myocardial injury were suggested.

ABSTRACT: Patients with ocular defects frequently present with significant local anatomical deficiencies and complex histories and require extensive time and resource inputs to treat. This case report describes the conservative management of an ocular defect completed in a postgraduate prosthodontics clinical residency program utilizing a novel threaded iris fabrication technique.

ABSTRACT: Pre-septal and orbital cellulitis are more commonly seen in children than in adults. The incidence of pediatric orbital cellulitis is 1.6 in 100,000. The impact of COVID-19 has led to the increasing practice of nasopharyngeal swab surveillance. We presented a case of rare pediatric orbital cellulitis complicated with subperiosteal abscess secondary to severe acute sinusitis following a nasopharyngeal swab. A 4-year-old boy was brought in by his mother with increasing painful left eye swelling and redness. Three days prior, the patient developed a fever and mild rhinitis with loss of appetite which raised concerns about COVID-19. He had a nasopharyngeal swab on that same day and tested negative. Clinically, there was marked erythematous and tender periorbital and facial oedema involving the left nasal bridge, maxilla extended to the left upper lip with a deviation of the left nasal tip contralaterally. Computed tomography confirmed left orbital cellulitis with left eye proptosis, fullness of left maxillary and ethmoidal sinuses and left subperiosteal abscess. The patient received empirical antibiotics and surgical intervention promptly and recovered well with improvements in ocular symptoms. The nasal swabbing techniques may vary among practitioners, and it is associated with extremely low risks of severe complications from 0.001% to 0.16%. Whether the swab had aggravated the underlying rhinitis or traumatized the turbinates leading to sinus drainage obstruction; a nasal swab may impose the risk of severe orbital infection in a susceptible pediatric patient. Any health practitioner conducting the nasal swab should be vigilant about this potential complication.
