Abstract Statement of problem Whether topical anticaries medicaments used in the oral environment will affect the surface integrity of restorative materials is uncertain. Purpose The purpose of this ...in vitro study was to investigate the effect of various anticaries agents on the surface roughness of 3 different restorative materials. Material and methods Sixty-four specimens of each restorative material (feldspathic porcelain, Ni-Cr metal ceramic alloy, and Ti-6Al-4V titanium alloy) were prepared and separated into 4 equal groups for soaking in anticaries agents (Prevident Dental Rinse, ACT mouth wash, chlorhexidine gluconate, and water). A profilometer was used to measure surface roughness before and after soaking the materials for 2 years of simulated usage. The mean change in surface roughness for each specimen was calculated. Statistical analysis was performed with a 2-way ANOVA, followed by the Tukey HSD test (α=.05). Results A significant interaction was found between the materials and anticaries agents (F=2.64, P =.02). The significant interaction was between Prevident and chlorhexidine gluconate. Porcelain specimens soaked in Prevident produced a negative change (−0.072 ±0.35 μm) in surface roughness (smoother surface), while chlorhexidine gluconate produced a positive change (0.094 ±0.42 μm) in surface roughness (rougher surface). Conclusion Within the limitations of this in vitro study, it can be concluded that Prevident Dental Rinse and chlorhexidine gluconate may cause a change in the surface roughness of feldspathic porcelain.

eBook
A state-of-the-art guide on oral cancer management from distinguished experts! Oral Cancer: Evaluation, Therapy, and Rehabilitation edited by prominent Johns Hopkins clinicians and educators Carole ...Fakhry, Karen Pitman, Ana Kiess, and David Eisele provides a comprehensive, state-of-the-art review on the diagnosis and management of oral cancer. This unique resource fills a void in the literature by exploring surgical and reconstructive issues specific to each subsite of the oral cavity. Important pre- and post-treatment evaluations by dental, speech language pathology, and the oncologic care team are reviewed. The comprehensive book is divided into 10 sections, each focused on different facets of the patients' trajectory. The text starts with epidemiology of oral cavity cancer and discussion of patient populations at increased risk of oral cavity cancer. The book details pre-cancers, multidisciplinary diagnostic evaluations, treatment, post-treatment, recurrent and metastatic oral cancer, and palliative care, concluding with future directions such as chemoprevention. A full spectrum of oral neoplasms are covered in depth, including different types of squamous cell cancer, primary malignancies of the mandible, and sublingual and minor salivary gland malignancies. Key Features * All oral cavity subsites are approached from both an ablative and reconstructive standpoint, with dedicated chapters focused on specific oral cancer reconstructive techniques * Discussion of oncologic considerations encompassing radiation and medical oncology including definitive radiation therapy, brachytherapy, adjuvant radiation therapy, and adjuvant chemotherapy/novel therapeutics * Clinical pearls cover complications of both surgery and radiation therapy, as well as psychological and dental implications of therapy * High-quality illustrations, photographs, and videos further elucidate impacted anatomy and techniques Residents and clinicians in otolaryngology-head and neck surgery, oral and maxillofacial surgery, head and neck reconstructive surgery, medical oncology, and radiation oncology will benefit from reading this excellent resource. Dentists who wish to further their knowledge about oral cancers will also find it an invaluable reference.
