Prosthetic Management of Severe Mandibular Deviation in a Hemi-Mandibulectomy Patient Following Osteoradionecrosis.

Rehabilitation of a patient after hemi-mandibulectomy without reconstruction represents a prosthodontic challenge. Indeed, mandibular deviation and decreased occlusal contacts are a common presentation post-surgery. This paper reports on a patient who presented with these challenges and where chronic osteoradionecrosis has resulted in significant mandibular deviation. A maxillary cobalt chrome mandibular deviation device, designed with palatal bite plane and constructed using 3D printing methods, resulted in a successful outcome. The authors aim to show how restorative management of similar patients can be successful using a modern approach.

Implant retention systems for implant-retained overdentures.

Implant retained overdentures are being increasingly utilised in both general and specialist practice to rehabilitate patients with missing teeth, particularly those that are edentate. This article aims to inform the reader of a variety of retention systems that are available to retain an implant overdenture and to understand how these systems work, their advantages and disadvantages and to outline some of the clinical and treatment planning considerations involved in selecting the most appropriate retention system for patients.

A practitioner's guide to gutta-percha removal during endodontic retreatment.

Endodontic retreatment can be a challenging task that can result in many complications if not approached cautiously. Many of these difficulties revolve around regaining access to the pulp chamber through extensive coronal restorations and removing residual root filling material, the commonest being gutta-percha (GP), from within obturated canals. This can often be an untidy, time consuming process that places teeth at a greater risk of iatrogenic injury and inhibits the operator achieving the necessary chemical disinfection required to eliminate the persistent apical disease. Therefore the following article aims to aid practitioners, particularly those who are unfamiliar, with accessing and removing GP from endodontically treated teeth. The outlined systematic approach is accessible in general practice, where the vast majority of endodontic treatment is conducted, requires basic equipment and with the correct experience can be applied to both straight and curved canals. By overcoming this initial stage of retreatment, subsequent chemical disinfection, which is critical to success, can be carried out to a higher standard reducing risks of re-infection.

The restorative management of microdontia.

Microdontia is a dental abnormality that will often present to the dental practitioner due to the aesthetic concerns of the patient. Treatment is therefore aimed at addressing the aesthetics issue of the patient and this can present a number of challenges which may require a multidisciplinary approach in its management. This article presents the restorative management of localised and generalised microdontia.

Radiographic evidence of postoperative healing 12 years following root canal treatment--a case report.

A case with evidence of radiographic healing of a periapical lesion 12 years after root canal treatment is presented. The use and limitations of previously produced guidelines on radiographic follow-up intervals are discussed. Questions are raised about what is known of the healing process and when further treatment should be instituted. The reliance on single radiographs alone when making treatment decisions is discouraged.

Paracetamol overdose as a result of dental pain requiring medical treatment - two case reports.

Two cases of unintentional paracetamol overdose are presented. Over a one month period these patients presented to an Accident and Emergency (A&E) department with symptoms of paracetamol toxicity, following the ingestion of large quantities of analgesia for the self treatment of dental pain. In one case the patient had no access to a dentist. Both patients required admission under the care of the medical on-call team and required anti-toxicity treatment to prevent permanent liver injury. Subsequent referrals were made to the oral and maxillofacial surgery team who provided emergency dental treatment and advice on further dental care. This paper highlights the significant signs and symptoms of paracetamol overdose about which dental practitioners should be aware. It also describes the management principles required to prevent potentially life threatening liver damage. Discussion is also made of the potential impact on patients struggling to cope with pulpal pain without access to a general dental practitioner.
