Delayed eruption of permanent dentition and maxillary contraction in patients with cleidocranial dysplasia: review and report of a family

Introduction. Cleidocranial dysplasia (CCD) is an inherited disease caused by mutations in the RUNX2 gene on chromosome 6p21. This pathology, autosomal dominant or caused by a spontaneous genetic mutation, is present in one in one million individuals, with complete penetrance and widely variable expressivity. Aim. To identify the incidence of these clinical findings in the report of the literature by means of PubMed interface from 2002 to 2015, with the related keywords. The report of local patients presents a clinical example, related to the therapeutic approach. Results and Discussions.

Treatments of sleep bruxism in children: a systematic review and meta-analysis

Objective: Treatment of sleep bruxism (SB) in children is not well established. The aim of this study was to develop evidence-based recommendations on SB therapy in children between the ages of 2 and 17. Methods: A systematic review and meta-analysis was conducted. Literature searches were performed using MedLine (PubMed), Web of Science, Scopus, and the Cochrane Library (November 30 2017). Results: The search strategy identified 268 potential articles; 10 papers were included in the qualitative synthesis and 3 in the meta-analysis, for a total of 94 patients.

Orthodontic screening and treatment timing in preschoolers

Dental and stomatologic problems in childhood need to be diagnosed and managed with multidisciplinary protocols focusing around the children an appropriate prevention, diagnosis, and care program. Therefore, it is paramount to avail of screening tools that provide an indication of in-depth multidisciplinary diagnostic flow. The aim of this study is to detect and evaluate malocclusion problems and predisposing factors in an Italian preschooler population.

Cyclic fatigue of Reciproc and Reciproc Blue nickel-titanium reciprocating files at different environmental temperatures

Introduction: The aim of the present study was to investigate the impact of ambient temperature on the life span of nickel-titanium (NiTi) files. Methods: Cyclic fatigue testing of NiTi instruments was performed in a stainless steel artificial canal. During the experiment, 4 different temperatures (0°C, 20°C, 35°C, and 39°C) were used in a thermostatic bath controlled using electronic and infrared controls.

Cone-beam computed tomographic analysis on root and canal morphology of mandibular first permanent molar among multiracial population in Western European population

Objectives: In the present study, confluent canals in the mandibular first molar's mesial root were investigated in an Italian population by means of cone-beam computed tomography (CBCT). Materials and Methods: A total of 200 molars, selected from the CBCT examinations of 130 patients who required this type of X-ray study as part of their dental treatment, were examined.

Cone-beam computed tomography in the assessment of periapical lesions in endodontically treated teeth

Objective: This study aimed to evaluate the relationship between the quality of the coronal restoration and the root canal filling on the periapical status of endodontically treated teeth using CBCT. Materials and Methods: CBCT data were obtained from the records of patients who deny any dental treatment in the 2 years prior to the CBCT examination. CBCT images (90 kVp and 7 mA, exposure time of 23 s, and a voxel size of 0.2 mm, with a field of view of 13 cm × 13 cm) of 1011 endodontically treated teeth were observed.

Nuclear magnetic resonance imaging in endodontics: a review

Introduction: This review analyzes the increasing role
of magnetic resonance imaging (MRI) in dentistry and
its relevance in endodontics. Limits and new strategies
to develop MRI protocols for endodontic purposes are
reported and discussed. Methods: Eligible studies
were identified by searching the PubMed databases.
Only original articles on dental structures, anatomy,
and endodontics investigated by in vitro and
in vivo MRI were included in this review. Original articles
on MRI in dentistry not concerning anatomy and

A preliminary assessment of a new dedicated endodontic software for use with CBCT images to evaluate the canal complexity of mandibular molars

Aim To investigate in vivo the complexity of canals
within mesial roots of mandibular molars using 3D
EndoTM software linked to CBCT images.
Methodology The CBCT images of 100 mandibular
first molars were analysed using the 3D EndoTM
software. The number of canals in the mesial roots,
the presence of apical confluences, the canal lengths
and the canal configurations using Vertucci’s classification
were evaluated in buccolingual (BL) and
mesiodistal (MD) views. The software allowed the

A comparative study of mechanical resistance of two reciprocating files

Background: To evaluate the cyclic fatigue resistance of two different Nickel-Titanium instruments, Reziflow (Komet, Brasseler GmbH & Co., Lemgo, Germany) and WaveOne Gold (Dentsply Maillefer, Ballaigues, Switzerland). Material and Methods: Two groups of 20 different NiTi endodontic instruments of identical tip size of 0.25 mm were tested; Reziflow and Wave-One Gold primary. Cyclic fatigue testing was performed in a stainless steel simulated root canal manufactured by reproducing the instrument's size and taper.

Measurement of torque generated during intracanal instrumentation in vivo

Aim: To compare two different clinical techniques when using endodontic rotary instruments by monitoring the torque in vivo. Methodology: Ten single-rooted maxillary anterior teeth were prepared by an endodontist using size 25,.06 taper TF rotary instruments (KerrEndo, Orange, CA, USA). All instruments were rotated at 500 rpm with maximum torque set at 2.5 N cm using an endodontic motor (Kavo, Biberach, Germany), which automatically recorded the torque values every 1/10 of a second.
