Abstract: Background: The search for an alternative to titanium dental implants has been ongoing for over 50 years. While titanium implants have significantly improved patients' quality of life, concerns about titanium sensitivity and corrosion have prompted interest in ceramic implants. Zirconia, in particular, offers biocompatibility and aesthetic benefits, especially for patients with thin gingival biotypes or those prone to gingival recession. Objective: This review aims to summarize the current knowledge on the use of zirconia ceramics in dental implant prosthodontics and assess its potential to replace titanium while maintaining high success rates. Methods: A review of the literature was conducted, focusing on zirconia implants, including one-piece and two-piece designs, covering mechanical properties, osseointegration, clinical outcomes, and challenges. Results: Zirconia implants show promising advantages, such as reduced sensitivity, minimal ion release, and improved aesthetics, particularly in patients concerned with the cosmetic outcomes of titanium implants. However, challenges remain, including mechanical fragility, surface treatment needs, and the risk of early failure. Despite these challenges, advancements in zirconia implant design and surface modifications have led to improved clinical outcomes, though zirconia implants have not yet reached the routine use of titanium implants. Conclusions: Zirconia implants present potential as a non-metallic alternative to titanium. However, their clinical use is still evolving, and further research and development are needed to ensure their long-term success and mechanical performance.

Abstract: Effective management of an expelled tooth requires its rapid transport to the dental office, in a liquid adapted to cell survival. For this, some preservation media have been evaluated in tropical areas with regenerative and antibacterial properties. These inaccessible and/or non-regenerative media have pushed our research towards alternative media including Aloe schunfurthii. Our general objective was to evaluate the antibacterial activity of Aloe schweinfurthii gel on the survival of periodontal ligament cells of an expelled immature permanent tooth. To achieve this objective, we conducted an experimental study. It was carried out at the Yaoundé University Hospital on extracted immature permanent premolars that were preserved in Aloe schweinfurthii gel at different dilutions and pH. Cell vitality was read using optical microscopy after aqueous eosin staining at three-hour intervals. The antibacterial activity was determined from bacterial samples of the periodontal ligaments of the premolars according to three successive steps ranging from the culture of the bacterial strains to the determination of the diameters and the inhibition parameters. The Chi 2 test was used to compare the vitality of the different media. The methodology used allowed us to obtain results which showed that the Aloe schweinfurthii gel had a CMB/MIC ratio lower than 4, revealing a bactericidal activity on all the bacteria tested. The results obtained allowed us to conclude that the Aloe schweinfurthii gel is bactericidal in the conservation of the cells of the periodontal ligaments of an expelled immature permanent tooth.

Abstract: Oral chronic graft versus host disease (OcGvHD) is characterized by a myriad of clinical signs and symptoms. The oral health status can be debilitating to the patient by exacerbated mucosal symptoms and decreasing quality of life. Oral manifestations may acutely present as mild to moderate erythematous lesions on mucosal surfaces, painful recurrent mucosal ulcers, and salivary gland hypofunction. At later stages, oral lesions presents with more severe signs and symptoms, including lichenoid lesions characterized by white striations, plaques, and erosions resembling oral lichen planus, mucosal atrophy characterized by thin, fragile mucosa prone to ulcerations and oral infections, trismus due to temporomandibular joint fibrosis, persistent salivary gland hypofunction leading to dysphagia and increased risk of caries and oral candidiasis, and heightened susceptibility to bacterial and viral infections due to impaired mucosal integrity. Amongst oral manifestations, other organs may be involved including the skin, eyes, liver and gastrointestinal tract. The oral manifestations of OcGvHD should be carefully monitored for its progression due to its malignant potential. This case report presents oral manifestations of OcGvHD appeared to develop 4 months after allogeneic hematopoietic cell transplantation in a 58-years old male patient who was referred to the Oral Medicine clinic from his hematologist for evaluation of widespread oral lesions.
