The intent of this article was to analyze the potential hazards and risks involved in persons exposed to prosthodontic practice. These risks include exposure to physical and chemical hazards, dental materials, infectious environment, inappropriate working pattern and psychosocial stress. The potential harm of these hazards and its prevention is highlighted. Prosthodontists, students, dental technicians, and others working in the prosthodontic clinics and laboratory should be aware of the specific risk factors and take measures to prevent and overcome these hazards.

Tooth eruption is a localised event whereby the signals for eruption for a given tooth are synthesised in the dental follicle of that tooth with a possible cross talk of signals coming from the adjacent stellate reticulum. The eruption process requires alveolar bone resorption that is primarily regulated by the dental follicle. This is reflected by the fact that failures of eruption often can be traced to either osteoclast deficiencies or to dental follicle abnormalities. Recent advances in application of molecular techniques to animal models allowed for better understanding of gene regulatory events involved in the physiology of tooth eruption. This article attempts to consolidate and organise the facts that offshoot from animal studies.

Management of implant failures is difficult, especially implant fixture fracture where it is complicated and requires multispecialty care. The aim of this report is to describe the challenges of treatment planning and management of implant fixture fracture with tooth wear on patient with financial constraints. A 67-year-old retired male patient came to the dental clinic with a complaint of a mobile implant-supported fixed prosthesis, fractured implant fixture and attrited lower dentition. Treatment plan was planned around low cost with the biggest benefit of the patient. Multispecialty care is involved such as root canal treatment, implant removal, restoration of remaining dentition and replacement of missing teeth with removable prosthesis. The patient was reviewed after a month of completing full treatment resulted in a good treatment outcome. Lack of maintenance regimen leads to failure and mobility of the implant prosthesis. Proper maintenance protocol, post-insertion instructions, and good patient compliance are the key factors in determining longevity of the restoration.
