Wear Behaviour of Polymer-Infiltrated Network Ceramics, Lithium Disilicate and Cubic Zirconia against Enamel in a Bruxism-Simulated Scenario.

The present study aimed to evaluate the wear rate of polymer-infiltrated network composites and ceramics against enamel in a bruxism-simulated scenario. Ninety-six ( = 96) molars were divided into six groups ( = 16) according to their occlusal material: group 1-a polymer-infiltrated network ceramic (PINC); group 2-a second polymer-infiltrated network ceramic (PINC2); group 3-nanohybrid resin-based composite (CO); group 4-cubic zirconia (ZR); group 5-lithium disilicate (LS); and group 6-sound enamel (EN). A laser scanner was used to digitalize all of the occlusal surfaces before and after a fatigue test, which was conducted with a chewing simulator set at 80 and semicircular movement in order to simulate bruxist movement and loads.

Clinical Behavior of the Gingival Margin following Conservative "Coronally Dynamic" Restorations in the Presence of Non-Carious Cervical Lesions Associated with Gingival Recession: A Pilot Study.

Gingival recessions (GR) are often associated with the presence of non-carious cervical lesions (NCCL). The latter result in the disappearance of the cement-enamel junction (CEJ), with consequent difficulties both in measuring the recession itself and in performing root coverage techniques. The restoration of cervical lesions is consequently an important aspect in the treatment of GR, with the re-establishment of a "new" CEJ.

An Evaluation of Jaw Tracking Movements in Patients with Total Joint Replacements versus a Control Group.

Background and Objectives: One form of treatment for degenerative temporomandibular joint diseases such as osteoarthritis, rheumatic arthritis, TMJ ankylosis, and condylar resorption is total joint replacement. The aim of this study was to examine the function of the temporomandibular joint after prosthetic joint replacement. Materials and methods: Fifteen patients with unilateral or bilateral TMJ total joint replacements and 15 healthy controls were evaluated via a SICAT JMT+ device.

Do Chemical-Based Bonding Techniques Affect the Bond Strength Stability to Cubic Zirconia?

This study evaluated the effectiveness of chemical-based adhesive techniques on promoting immediate and aged bond strength between zirconia and luting cement. A total of 128 discs of zirconia were divided into 4 groups ( = 32) according to the adhesive treatment: tribochemical silica-coating followed by silane (Silane Primer, Kerr) and bonding (Optibond FL, Kerr), Signum Zirconia Bond (Hereaus), Z-Prime Plus (Bisco), and All-Bond Universal (Bisco). Composite cylinders were cemented on the zirconia sample with Duo-Link Universal (Bisco).

Temporomandibular disc displacement with reduction treated with anterior repositioning splint: a 2-year clinical and magnetic resonance imaging (MRI) follow-up.

Clicking may appear in the initial, middle, or final phase of mandibular opening. Magnetic Resonance Imaging (MRI) is the most appropriate diagnostic imaging for diagnosing disc position. With anterior repositioning splint (ARS), disc recapture is achieved through a change in the position of the condyle to encourage adaptation of the retrodiscal tissues.

Decision-making process as guide to the management of non-carious cervical lesions with and without painful symptomatology.

The aim of this study is to develop a decision-making path for the management of non-carious cervical lesions (NCCLs) associated with or without dentin hypersensitivity (DH) This will allow to limit or delay invasive approaches identifying the causes that produced them. The need for this review is because there are no clear guidelines in the current literature for the treatment of NCCLs. Usually, the selection of the best therapy option is postponed to clinical judgment which can be influenced by a patient's demands (aesthetic, symptomatologic reasons or worsening of pre-existing NCCL).

A Comparison between Piezoelectric Devices and Conventional Rotary Instruments in Bone Harvesting in Patients with Lip and Palate Cleft: A Retrospective Study with Clinical, Radiographical, and Histological Evaluation.

Introduction: Orofacial clefts are congenital malformations characterized by an incomplete shaping of structures that separate the nasal from the oral cavity and can affect the right, left, or both sides. The aim of the present study is to assess, with clinical, radiographical, and histological evaluations, the efficacy of piezoelectric devices compared to traditional rotating instruments in the bone harvesting in patients with history of cleft.

Materials And Methods: We have conducted a retrospective analysis on 20 patients with a history of orofacial clefts that were operated on from February 2014 to June 2017.

Clinical Application of the PES/WES Index on Natural Teeth: Case Report and Literature Review.

The use of reliable indices to evaluate the aesthetic outcomes in the aesthetic area is an important and objective clinical aid to monitor the results over time. According to the literature various indices were proposed to evaluate aesthetic outcomes of implant-prosthetic rehabilitation of the anterior area like Peri-Implant and Crown Index [PICI], Implant Crown Aesthetic Index [ICAI], Pink Esthetic Score/White Esthetic Score [PES/WES], and Pink Esthetic Score [PES] but none of them was related to prosthetic rehabilitation on natural teeth. The aim of this study is to verify the validity of PES/WES index for natural tooth-prosthetic rehabilitation of the anterior area.

Dentin caries progression and the role of metalloproteinases: an update.

Aim: This review aims to summarise our understanding of the destructive role of acid environment and metalloproteinases in dentin caries progression using a review process.

Method: The acids resulting from consumption of sugars by acidogenic and aciduric bacteria can cause demineralisation of the tooth surface, but are not able to cause caries-like lesions. The appearance of such lesions requires the activation of enzymatic proteolysis in an acidic environment for degradation of the dentin organic matrix, leading to cavity formation.

Effectiveness on oral pain of 808-nm diode laser used prior to composite restoration for symptomatic non-carious cervical lesions unresponsive to desensitizing agents.

This study compares sensitivity reduction after dental restoration with and without prior diode laser (DL) irradiation for cervical dentine hypersensitivity (CDH) from non-carious cervical lesions (NCCLs) unresponsive to desensitizing agents. Eighty-eight teeth of 28 subjects (21 females; age 23-64 years), with CDH from NCCL were included in this study. NCCLs of each oral quadrant were randomized in two groups (study group (SG)) to estimate the sensitivity reduction after dental restoration (SG-1) compared with the DL irradiation used prior to restoration placement (SG-2).

Combined orthodontic-surgical management of a transmigrated mandibular canine.

The presence of an impacted mandibular canine is one of the most difficult challenges that an orthodontist will meet. Orthodontic treatment is planned on an individual basis after thoroughly considering the patient's overall facial and dentoskeletal characteristics; the duration, risks, and costs of treatment; patient preferences; and the orthodontist's experience. This article reports an orthodontic treatment of a boy, age 12.

Intraocular pressure evaluation in healthy eyes and diseased ones using contact and non contact devices.

Methods: The study included 76 eyes of 76HS, 15 eyes of 15 KC patients and 18 eyes of 18 subjects that underwent REF. Each participant underwent a complete ophthalmic evaluation, IOP measurement with GAT, DCT, ORA and CST.

Class I restoration margin quality in direct resin composites: A double-blind randomized controlled clinical trial.

Purpose: To evaluate the margin quality of direct resin composite restorations comparing the enamel-dentin adhesive standard procedure with additional use of adhesive layer at the external outline.

Methods: A total of 648 teeth with Class I occlusal lesions in molars and premolars were randomly selected and distributed into two groups of 324 each in order to compare the margin quality with two restoration strategies. Lesions were sealed with the standard adhesion procedure for direct resin composite restorations (Group 1) and with an additional procedure of enamel adhesive on the outer boundary of the finished restoration (Group 2).
