OBJECTIVE: Optical coherence tomography (OCT) is a clinical standard in ophthalmology. Currently, its application in dentistry is gaining increasing interest. In this study, we tested the possibility to use a modified commercially available spectral domain OCT (SD-OCT) to assess the layer thickness of orthodontic surface sealants. MATERIALS AND METHODS: Reference samples of surface sealants for calibration and repeatability testing were measured using a micrometer screw...

Despite nearly a century of research, the treatment of cervical dentinal hypersensitivity (DH) remains challenging. This case report discusses the indications for different approaches to the treatment of DH in a single patient; the chosen alternatives took into account the different degrees of tooth wear and levels of pain at different sites. A 31-year-old woman reported DH in the maxillary right canine and first premolar and the maxillary left lateral incisor and canine in response to thermal, tactile, and osmotic stimuli...

BACKGROUND: Fissures of the occlusal surface of equine cheek teeth are commonly encountered during oral examination but their aetiology is unknown. OBJECTIVES: To examine the prevalence and characteristics of occlusal fissures in cadaver teeth. It is hypothesised that their prevalence is influenced by masticatory forces. Consequently, their possible association with wear disorders and occlusal angles were examined. STUDY DESIGN: Cross-sectional survey...

The Late Archaic in northeastern North America (4500-2800 B.P.) pre-dates reliance on pottery and domesticated plants. It is thought to reflect a highly mobile, seasonal migratory foraging/hunting regimen. A juvenile skeleton with pervasive bone wasting and fragile jaws from the Hind Site (AdHk-1), ca. 3000 B.P., southwestern Ontario, provides evidence of the social context of her family group, including aspects of mobility and food management. The well-preserved bones and teeth are considered in bioarchaeological context...

This article provides an overview of the nutritional and patient-related risk factors involved in the aetiology of erosive tooth wear (ETW) and the preventive strategies to counteract them. The first step is to diagnose clinical signs of ETW and to recognise causal factors. Low pH and high buffer capacity of foods/drinks are the major risk factors, while the calcium concentration is the main protective factor. Reduction of frequency of consumption and contact time of erosive foods/drinks with the teeth, use of straws appropriately positioned and consumption of dairy products are advisable...

This manuscript summarises the reasons behind choosing indirect restorations in the treatment of tooth wear. The purpose of this article is to discuss the use of crowns as a restorative treatment option for tooth wear. There are also challenges with the use of composites as they can repeatedly fail and in these situations the indications for crowns for treatment of tooth wear is worthy of consideration. This article is part of a themed issue discussing the management of tooth wear.

Attrition is an enigmatic condition often found in older individuals and often as a result of bruxism which can take place as a result of either day bruxism, night bruxism or both. Various studies and systemic reviews clearly shown that tooth wear is an age-related phenomena and the last Adult Dental Health Survey showed that 15% of participants showed moderate wear and 3% severe wear with 80% of patients over 50 years of age showing signs of wear. This review examines current theories around the aetiological factors contributing to attrition together with the clinical management of attrition focusing on minimal intervention where possible...

Erosion is a common phenomenon in the general population of developed countries. However, due to variations in indices, sample sizes and general study designs, it is difficult to compare the various studies and to estimate actual global prevalence. Therefore, the aim of this present paper is to give a narrative overview on the data available on the global prevalence of erosion. Information on prevalence is not available from each country; in particular, data from Asia, Africa, South America, North America and large parts of South-Eastern Europe are unavailable...

This paper aims to provide the dentist with practical guidance on the technique for direct composite restoration of worn teeth. It is based on current evidence and includes practical advice regarding type of composite, enamel and dentine preparation, dentine bonding and stent design. The application of direct composite has the advantage of being additive, conserving as much of the remaining worn tooth as possible, ease of placement and adjustment, low maintenance and reversibility. A pragmatic approach to management is advocated, particularly as many of the cases are older patients with advanced wear...

This paper explores some of the most relevant questions faced by dental practitioners when diagnosing early erosive tooth wear (ETW) and implementing non-operative management of this condition over time. It focuses on the identification of clinical signs and common locations of ETW lesions, the assessment of individual risk and the implementation of non-operative management strategies, aiming to arrest and/or reduce the rate of ETW progression and avoid its advance to pathological stages. To this end, we present a novel and comprehensive approach that considers the whole dentition of patients rather than individual groups of teeth or dental surfaces only, illustrating it with a series of clinical photographs...

The aim of this article is to describe a systematic approach that facilitates the establishment of a clear and appropriate diagnosis when a dentate patient presents with tooth wear involving their aesthetic zone. It will also detail the protocols that are required to allow for the development of an acceptable aesthetic prescription within the limits of the functional constraints presented by the patient (where active restorative intervention may be indicated), as well as to communicate the manner by which this information can be transferred to ultimately enable the successful and predictable rehabilitation of the affected areas...

This paper explains a conservative, pragmatic and minimally invasive intervention concept for the treatment of severe tooth wear patients based on the Radboud Tooth Wear Project in the Netherlands. Guidelines and flowcharts for management of severe tooth wear patients and rehabilitation in increased vertical dimension of occlusion are presented. We concluded that: (a) Restorative treatment is not always indicated, even for patients with severe tooth wear. (b) If the patient has no complaints, counselling and monitoring is probably the best option...

There are many reasons why it is vital that dental professionals identify signs and symptoms that suggest that an individual's erosive tooth wear (ETW) may be linked to a broader medical problem than just poor diet. Primarily, spotting an underlying medical cause for ETW increases the likelihood that further deterioration in the individual's oral health will be prevented. However, perhaps more importantly, many of the medical conditions which are commonly related to ETW can have serious and even possibly fatal consequences if left untreated or not diagnosed...

All fluoride sources help strengthen teeth against bacterial acids that cause caries. However, excessive exposure to dietary acids, which can result in dental erosion, presents a more aggressive level of challenge compared to caries. Despite the fact that almost all toothpastes contain fluoride, both the incidence and prevalence of dental erosion appear to be on the rise. This article: (1) describes key differences between caries and dental erosion and the ability of different fluoride sources to help prevent erosion; (2) discusses the importance of the evaluation of patients for dental erosion at the earliest stages using the Basic Erosive Wear Examination scoring system to help assess and educate patients; and (3) provides evidence-based information for making specific recommendations to patients with dental erosion...

With the increasing number of young adults seeking orthodontic treatment to improve their smile esthetics or oral function, the time spent wearing brackets is one of the biggest challenges for these patients. Various surgical techniques have been developed over the years to accelerate tooth movement and reduce the total treatment time. A newly introduced, minimally invasive procedure namely piezopuncture, which uses a piezosurgical tool to create multiple cortical punctures through the gingiva, is presented in this report of two extraction cases...

OBJECTIVE: To evaluate the wear intensity and surface roughness of occlusal veneers on premolars made of microhybrid composite resin or two kinds of ceramics in vitro after the thermocycling and cyclic mechanical loading tests. METHODS: In the study,24 fresh extracted human premolars without root canal treatment were prepared (cusps reduction of 1.5 mm in thickness to simulate middle to severe tooth wear, the inclinations of cusps were 20°). The prepared teeth were restored with occlusal veneers made of three different materials: microhybrid composite, heat-pressed lithium disilicate ceramic and computer-aided design/computer-aided manufacturing (CAD/CAM) lithium disilicate ceramic in the thickness of 1...

Despite its long history of scientific study, the causes underlying the extinction of the insular hominoid Oreopithecus bambolii are still a matter of ongoing debate. While some authors consider intense tectonism and invading species the cause of its extinction ca. 6.7 Ma, others propose climatic change as the main contributing factor. We rely on long-term patterns of tooth wear and hypsodonty of the Baccinello and Fiume Santo herbivore-faunas to reconstruct changes in habitat prior to, during and after the extinction...

An acidic diet has been associated with erosive tooth wear. However, some people who consume dietary acids develop erosive tooth wear and some do not. This review paper provides an overview of the risk factors of dietary acid consumption which increase the likelihood of developing severe erosive tooth wear. Increased frequency of dietary acid consumption, particularly between meals appears to be the predominant risk factor. However, habitually drinking acidic drinks by sipping them slowly or swishing, rinsing or holding acidic drinks in the mouth before swallowing will also increase risk of progression...
