Distribution of Malocclusion Traits in the Pediatric Population of Milan: An Observational Study.

Epidemiological investigations define the prevalence and distribution of the various types of malocclusions, and can help to identify etiological factors and set the most correct orthodontic therapy. The goal of this study was to verify the prevalence and distribution of various types of malocclusions in the pediatric population. The study was performed on a sample of 350 patients (ages 5-9) being treated at the ASST Grande Ospedale Metropolitano Niguarda in Milan.

COVID-19 and Prosthetic Emergencies, Home Care in Fragile Patients: A Case Report.

A case of home care is proposed on a frail non-ambulatory patient who presents an old lower total prosthesis in resin broken in several parts. The various pieces of the prosthesis were joined by the patient, as if it were a puzzle, using a glue for plastics and wood. The union of the parts attached with glue was the consequence of the lockdown in the COVID-19 period and of the economic hardship experienced by the elderly disabled patient during the pandemic period.

Laser Decontamination and LED Photobiomodulation Promote Bone Regeneration and Wound Healing by Secondary Intention, in Alveolar Ridge Preservation-Clinical and Radiographic Evaluation: A Pilot Experience.

Tooth loss reduces crestal bone with important resorption of alveolar dimensions, reducing the possibility of placing implants after wounds healing. The goal of this pilot experience was to consider, in alveolar ridge preservation, the regenerative and decontaminating potential of oxygen high-level laser therapy (OHLLT), a high-frequency and high-power diode laser combined with hydrogen peroxide 10 volumes 3%, and to evaluate wound closure during the 14-21 days after surgery. For this study we selected 15 patients (age range from 30 to 70 years old) who underwent alveolar ridge preservation (three patients were treated in the anterior maxilla, 12 in the mandibular jaw, with molars and premolars involved).

Reducing the spread of COVID-19 within the dental practice: the era of single use.

The year 2020 will be remembered around the world for the Coronavirus pandemic. The better-known Coronavirus disease (COVID-19) is transmitted between individuals through the droplets produced by infected people and is an infectious disease caused by a type of Coronavirus when they exhale, cough or sneeze, or touch a contaminated surface and then touch their eyes, nose or mouth. The pandemic has activated all those measures that provide for a state of emergency with consequent remodeling of health facilities in cases of urgency that cannot be deferred.

Maxillary Orthodontic Expansion Assisted by Unilateral Alveolar Corticotomy and Low-Level Laser Therapy: A Novel Approach for Correction of a Posterior Unilateral Cross-Bite in Adults.

The treatment of a true unilateral posterior crossbite often requires asymmetric maxillary expansion; however, this is challenging to achieve with conventional expansion methods because of several biomechanical limitations. In this paper, we introduce a new protocol for the treatment of a unilateral posterior crossbite in adults based on maxillary orthodontic expansion assisted by corticotomy and low-level laser therapy (LLLT) performed on the crossbite side. The study sample included 15 adults (8 females, 7 males) affected by a true unilateral posterior crossbite, with a mean age of 21.

Gene clustering analysis in human osseous remodeling.

Background: Tentative bioinformatic predictions were performed to comprehend the complexity of the gene interaction networks of the T lymphocyte cell cycle and of human periodontitis. This study aims to identify and rank genes involved in osseous augmentation or bone remodeling to obtain groups with more numerous predicted associations called the leader gene clusters.

Intraoral luting: modified prosthetic design to achieve passivity, precision of fit, and esthetics for a cement-retained, implant-supported metal-resin-fixed complete denture.

An intraoral luting technique between electroformed gold copings and a metallic framework for a cement-retained, implant-supported metal-resin-fixed complete-denture is presented. The peculiarity is the different prosthetic design with the metallic framework that was 1.5 mm shorter than the margin of the electroformed copings.

Immediate loading: a simple protocol to create a passively fitting provisional fixed implant-supported complete denture in 1 day.

Many studies have shown success with immediate loading of dental implants. The purpose of this paper is to report on a procedure that places implants with a sand-blasted and acid-etched surface and loads them with a fixed, provisional, immediately loaded mandibular complete denture, all in a single day. The various surgical, prosthetic, and laboratory phases are explained, with particular attention paid to a luting technique that is able to reduce prosthetic misfit.

Preliminary clinical and histologic evaluation of a bilateral 3-dimensional reconstruction in an atrophic mandible: a case report.

This article presents the case report of the bilateral 3-dimensional reconstruction of a posterior mandible in a 48-year-old woman. Titanium meshes and Regenaform demineralized freeze-dried bone allograft were used for bone regeneration. After 5 months the titanium mesh was removed, and after another 4 months, 4 Straumann sandblasted, large-grit, acid-etched implants were placed, 2 on each side of the mandible.

Lingual vascular canals of the mandible: the risk of bleeding complications during implant procedures.

Purpose: The aim of this article is to investigate the potential risk of a critical life-threatening hemorrhage due to the perforation of the lingual cortical plate and arterial trauma of the terminal branches of the sublingual artery. In fact, in many cases, implants are placed in the mandibular interforaminal region, and this area is also often involved in oral surgery as a bone donor site.

Materials And Methods: One hundred dry skull Caucasian mandibles and 100 computed tomographies (CTs) of the mandible of Caucasian patients were examined.

Association between serum values of C-reactive protein and cytokine production in whole blood of patients with type 2 diabetes.

Diabetes mellitus accelerates atherosclerotic processes, and it is known that inflammation plays a key role in atherosclerosis. The aim of the present study was to evaluate in patients with Type 2 diabetes whether serum levels of CRP (C-reactive protein) are associated with cytokine production in whole blood. A total of 89 outpatients with Type 2 diabetes were enrolled, and blood pressure, body mass index, fasting blood glucose, glycated haemoglobin, cholesterol, triacylglycerols (triglycerides) and hs-CRP (high-sensitivity CRP) were measured.

Usefulness of real time PCR for the differentiation and quantification of 652 and JP2 Actinobacillus actinomycetemcomitans genotypes in dental plaque and saliva.

Background: The aim of our study is to describe a fast molecular method, able to distinguish and quantize the two different genotypes (652 and JP2) of an important periodontal pathogen: Actinobacillus actinomycetemcomitans. The two genotypes show differences in the expression of an important pathogenic factor: the leukotoxin (ltx). In order to evidence this, we performed a real time PCR procedure on the ltx operon, able to recognize Aa clinical isolates with different leukotoxic potentials.
