When (and when not) to use the Dahl Concept.

The Dahl Concept describes the re-establishment of occlusal contacts after the provision of a planned localised appliance or restoration in supraocclusion. Initially developed to create space for prosthetic rehabilitation of anterior teeth suffering from localised wear, the principle has later been successfully applied to a variety of situations, including the Hall technique and resin-bonded bridges cemented in supraocclusion. Despite high levels of success seen in the relevant literature and widespread adoption in specialist care, the wider profession appears to be far more cautious in its use.

Improved Prediction of Body Mass Index in Real-World Administrative Healthcare Claims Databases.

Introduction: To continue closing the gap between the predictive modeling and its real-world application, we report a new data-to-prediction pipeline that advanced the state-of-the-art predictive performance of body mass index (BMI) classifications by integrating siloed claims databases via a common data model.

Methods: This study adapted the ensemble-based methodology of the baseline prediction model and focused on removing the silos in the claims databases. We applied the Super Learner machine learning algorithm (SLA) to learn a combined dataset consisting of 50% data from the Optum Date of Death database and 50% data from the IBM MarketScan Commercial Claims and Encounters (CCAE), and omitted the commonly used one-hot-encoding step and used multi-categorical variables directly in the feature engineering process.

The interdisciplinary management of patients with amelogenesis imperfecta - restorative dentistry.

This paper considers the role of the restorative dentist in the interdisciplinary management of patients with amelogenesis imperfecta. General restorative considerations as well as the techniques available are reviewed. Two clinical cases are described to illustrate this.

Amelogenesis imperfecta: the orthodontic perspective.

Orthodontics in patients with amelogenesis imperfecta can be complicated by commonly occurring dental features in this group as well as patient factors. In this article we examine ways to avoid the common pitfalls of orthodontic management and the importance of adequate and timely liaison between the general dental practitioner and the multidisciplinary team.

Managing the paediatric patient with amelogenesis imperfecta.

A diagnosis of amelogenesis imperfecta can present challenges for patient and clinician alike. This can be further complicated in a child due to cooperation and the ever-changing dentition. This paper looks at the ideals for management at various stages of the developing dentition but also considers the compromises which may have to be made depending on the child's ability to cope.

Amelogenesis imperfecta: an introduction.

Amelogenesis imperfecta (AI) is an inherited disorder that is associated with mutations in five genes (AMEL; ENAM; MMP20; KLK4 and FAM83H) with a wide range of clinical presentations (phenotypes). It affects the structure and appearance of enamel of all teeth, both in the primary and secondary dentition. In this review paper, we look at the epidemiology, classification, aetiology, clinical description and diagnosis of AI.

Multiple radio-opacities in an OPG: a case report of cavernous haemangioma of temporalis muscle with multiple phleboliths.

Intramuscular haemangiomas of the head and neck region are rare. They may present as an incidental finding, a mass or swelling, pain, tenderness, limitation of movement or cosmetic deformity. Treatment depends on the clinical signs and symptoms.

Management of periodontal disease in general dental practice.

Unlabelled: This paper reviews the important parameters deemed useful in the diagnosis and management of periodontal disease in general dental practice. We aim to highlight the importance of these when making a diagnosis and the necessary treatment undertaken in general dental practice before considering referral to specialist services. We also provide guidelines to assist the referral of patients for periodontal treatment in specialist care settings.

Facial aesthetics: is botulinum toxin treatment effective and safe? A systematic review of randomised controlled trials.

Background: The use of botulinum toxin type A (BTA) in facial aesthetics for the treatment of wrinkles has recently become more popular as an alternative to surgical techniques. However, its true efficacy and potential adverse effects are still unclear.

Objectives: The primary objective of this study was to review the efficacy of BTA in facial aesthetics.

The therapeutic use of botulinum toxin in cervical and maxillofacial conditions.

Data Sources: Medline, Cochrane Library and bibliographies of identified articles.

Study Selection: Studies of high methodological quality (systematic reviews or randomised controlled trials; RCT) were selected if considered use of botulinum toxin (BTX) either prophylactically or therapeutically, as an adjunct to dental implant therapy for temporomandibular disorders or for other maxillofacial conditions such as bruxism, masseteric hypertrophy, oromandibular dystonia or cervical dystonia.

Data Extraction And Synthesis: Only studies with high levels of evidence were evaluated.

Traumatic pseudolipoma: herniation of buccal fat pad, a report of two cases.

Traumatic pseudolipoma is a term used to describe intra-oral herniation of the buccal fat pad. A tear of the buccinator muscle and buccal mucosa allows the buccal fat pad to extrude into the oral cavity. Initially, the lesion can suggest a more sinister cause, but a history of trauma, an absence of mass before the accident, anatomical site and fatty appearance should suggest a diagnosis of traumatic herniation of buccal fat pad.

Development of a stain shade guide to aid the measurement of extrinsic dental stain.

Background: Accurate and reproducible assessment of extrinsic staining is pivotal to determining efficacy of some tooth whitening oral hygiene products. The aim of this study was: (1) to produce a stain shade guide to aid the in vitro and in vivo stain assessment (2) to assess intra- and inter-examiner reproducibility of stain assessment using the stain shade guide.

Method: Using chlorhexidine and tea, perspex and acrylic teeth specimens were stained.
