The sutures in dentistry

In oral surgery, the last phase of a surgical operation is represented by the tissues suture, that allows the wound lips edges approximation and their stabilization, to promote haemostasis, to avoid the alimentary residues accumulation on the incision line and allow the first intention healing. A good suture avoids that the displacing forces generated by the muscular insertions, functional movements and by the external agents destabilize or cause the surgical wound deiscence. The purpose of this study was to re-examine the suture threads characteristics, properties and biological interactions evaluating the different studies published in literature results and conclusions. In conclusion, the authors recommended the use of the different suture threads on the dependence of the oral surgery operation type that must be performed, of the patient compliance and of the various suture materials physical and biocompatibility characteristics

Digital work-flow

The project presents a clinical case in which the digital work-flow procedure was applied for a prosthetic rehabilitation in natural teeth and implants. Digital work-flow uses patient’s photo for the aesthetic’s planning, digital smile technology for the simulation of the final restoration and real time scanning to register the two arches. Than the scanning are sent to the laboratory that proceed with CAD-CAM production. Digital work-flow offers the opportunities to easily speak with laboratory and patients, gives better clinical results and demonstrated to be a less invasiveness method for the patient. Intra-oral scanner, digital smile design, preview using digital wax-up, CAD-CAM production, are new predictable opportunities for prosthetic team. This work-flow, compared with traditional methods, is faster, more precise and predictable

A novel technique to close large perforation of sinus membrane

Maxillary sinus floor elevation is generally accepted as a regenerative procedure to facilitate dental implants placement in the posterior atrophic maxilla. Although the sinus lift procedure is relatively safe, some potential problems could be occur. The most prevalent intraoperative complication is perforation of sinus membrane, which can lead to graft infection and early failure. The Aim of this work. Is to present a new technique to repair large perforation of sinus membrane. This case report. Is focused on a 10 mm perforation of sinus membrane occurred during preparation of the sinus window. The obliteration of the perforation was obtained by means of suturing sinus membrane with a resorbable material to the bone directly lateral to the osteotomy site. Sinus augmentation procedure could complete and the insertion of a graft was permitted

Effect of Toothpaste on the Surface Roughness of the Resin-Contained CAD/CAM Dental Materials: A Systematic Review

Background: The purpose of this review is to describe the possible effect of toothbrushing on surface roughness of resin-contained CAD/CAM materials. Methods: Systematic literature search for articles published in peer-reviewed journals between January 2000 and February 2020 has been conducted, which evaluated the effect of brushing on surface roughness of resin-contained CAD/CAM dental materials. The research was conducted in Scopus, PubMed/Medline, Web of Science, Embase, and Science Direct using a combination of the following MeSH/Emtree terms: “brushing”, “resin-based”, “dental”, “CAD/CAM”, and “surface roughness”. Results: A total of 249 articles were found in the search during initial screening. Fifty-five articles were selected for the full-text evaluation after the steps of reading of abstract/title and remotion of duplicate. Only six articles fulfilled the inclusion criteria. The Cohen’s Kappa agreement test showed an index of 0.91 for full-text. Discussion: Four of five selected articles identified an increase of surface roughness on resin-contained CAD/CAM materials after toothbrushing. Although all the articles examined used different toothpastes with no homogeneous relative dentine abrasivity (RDA) and cycles of brushing, the findings are about the same. The possible reason is attributable to the compositions of the resin-contained CAD/CAM materials. Conclusions: The surface roughness of most resin-contained CAD/CAM materials was affected by artificial toothbrushing. Correct knowledge of the composition of the dental material and toothpastes is fundamental to avoid an increase of surface roughness on prosthetic rehabilitation

Implant surgery and oral anticoagulant therapy: case report

This work aims to assess the risks both thromboembolic that bleeding of a management protocol “non-conservative” in patients on oral anticoagulant therapy (OAT) to be undergoing implant surgery. We decided to take a surgical “non-conservative” protocol, to insert four implants in the aesthetic zone, without using flapless surgery and the surgical template. In accordance with the hematologist, the value of INR is lowered and warfarin was replaced with heparin low molecular weight, to have a better coagulation’s control. The modern guidelines impose a protocol of conservative management in patients with OAT, with minimally invasive surgery, flapless, and use of surgical template to reduce the risk of uncontrolled bleeding. This, thanks to the teamwork between dentist and hematologist, thanks to careful adjustment of INR and the use of local haemostatic agents, were not encountered any problems with bleeding or intra or postoperative. Surgical treatment of patients with OAT is a real problem for the oral surgeon, to treat every time in association with the hematologist. Applying this type of surgical procedure, different from today’s guidelines, in our experience there were no post-operative complications (bleeding or bleeding); osseointegration has not been compromised and the prosthetic rehabilitation was completed successfully

Gnathological features in growing subjects

Aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) in a sample of consecutive subjects

Impact of SARS-CoV-2 on dentistry: a review of literature.

OBJECTIVE: SARS-CoV-2 is a new Coronavirus identified as the cause of Corona- virus disease in 2019 (COVID-19). The epidemic spread in China and beyond its borders, involv- ing 114 countries with more than 5 million dead. On March 11, the WHO declared the spread of SARS-CoV-2 to be a pandemic and encouraged nations to adopt harsh restrictive measures. Therefore, patients more and more often turn to dental offices only for emergencies. Healthcare professionals, including dentists, are at high in- fectious risk. In fact, the closeness to the oral cavity and nasopharynx and the use of drills or ultrasonic devices that cause aerosol release, make dental professions at high risk of bacterial and viral infections. The way patients are treat- ed has changed. In fact, it should be mandato- ry to carry out a pre-treatment telephone triage and the use of mouthwashes to reduce bacterial load. In the current pandemic, it is necessary to adopt specific safety protocols that can protect dental operators as well as limit the spread of the virus. The purpose of this review is to pres- ent an overview on ways to reduce the risk of SARS-CoV-2 contagion in dentistry by focusing on the immediate situation as well as by look- ing towards the future. MATERIALS AND METHODS: To reach the review purpose, we selected a series of studies using keywords “COVID-19” OR “SARS-CoV-2” in association with “dentistry” AND “safety proto- cols” AND “healthcare procedures” AND “individ- ual protection dispositive” AND “air transmission” AND “droplet”. We selected papers exclusively in English language, up to 1st January 2022. RESULTS: During future phases of the pan- demic, everywhere in the World, it is necessary to impose all dentistry team both a serological screening and the vaccination, as already estab- lished for all health staff in Italy. CONCLUSIONS: For own safety, it is an import- ant for the whole dentistry category constantly update the devices and the protocols adopted, as well as monitoring the real infectious threats, which may occur
