Results are shown at 12 months. The main factor for the success of this technique is the preservation of periodontal ligament cells. The unerupted teeth are the only ones that fully preserve the periodontal ligament, but they require greater surgical skills. Autotransplantation is a predictable treatment alternative to dental implants, being above all an option indicated to replace teeth with dental fissures or vertical root fractures or poor restorative and/or endodontic prognosis. The third molars are the most used teeth for transplantation, due to their indications for extraction in a high percentage preserving the entire periodontal ligament. The diagnosis by CBCT and the use of 3D- printed replicas of the tooth to be transplanted have meant a highly significant improvement in the prognosis and predictability of the technique. Key wordsDental autotransplant, tooth replica, third molar.

Treatment of facial fractures in children and adolescents has always been a challenge for oral surgeon. The choice of treatment type must take into account several factors. This systematic review aimed to evaluate closed versus open reduction of facial fractures for pediatric facial fractures.

A systematic review of the literature was conducted in three databases (PubMed/MEDLINE, Embase and The Cochrane Library) in accordance with the PRISMA statement. The PICO question was Conservative treatment is more appropriate than surgical treatment for reducing facial fractures in children and adolescents? The full papers of 41 references were analyzed in detail. Eleven papers were included in this systematic review one prospective study and ten retrospective studies. All studies evaluated the complication rate.

A total of 73 (7.68%) of the 950 patients experienced complications. Among these patients, 24 (3.85%) had been treated with conservative treatment and 49 (15.03%) with surgical treatment. The fixed-effection, open fracture reduction, pediatrics, treatment failure.

In recent times the deontology of the dental profession has acquired special relevance as a result of problems that dentists have had to face to resolve ethical conflicts.

Information on deontology in the dental profession has been compiled in publications of health sciences in general and specific codes for dentistry, while expressing opinions about the experience of the authors themselves who, from a humanistic and health overview are concentrated in the dental area.

This article presents our point of view of how the dentist-patient relationship should be in the face of current demands from patients and society, with a focus on the crucial role of ethical issues not only in undergraduate studies but also in the consideration of ethical questions in the specialization and in the usual practice. The dental profession has a special trust in the community, and the best dentist-patient relationship should be based on that trust, honesty, providing high-quality and appropriate treatment, and keeping the patient safe and healthy.

The patient has the right to be fully and adequately informed, as well as to participate in decisions about treatment. The dentist has a duty to put the patient first and treat her with her wishes in mind as long as these expectations are within the limits of accepted treatment. The dentist must provide dental care without discrimination or prejudice.

The fiber posts require a cut in the coronal portion to adjust it to the available clinical space. The cutting of posts cemented may generate tension via bur vibrations of drill on the bonding interface, with the possibility of decreasing the bond strength. Thus, this study aimed to evaluate if the moment of cutting the fiber posts has an effect on its bond strength when fixed with self-adhesive resin cement.

Thirty-six bovine teeth were randomly divided into three groups after endodontic treatment and post space preparation (n = 12) IAC- the fiber posts were cutting immediately after cementation; ACR - the fiber posts were cutting after coronal reconstruction with resin; Control - the fiber posts were not cut. The fiber posts were cemented with self-adhesive cement (RelyX U200 - 3M ESPE). After 24 h, the teeth were sectioned perpendicularly and the push-out test was performed in a universal testing machine at a speed of 0.5 mm/min, until failure. Data were analyzed using two-way ANOVA and Tukey's post-hoc test.

The effect of moment of fiber posts cutting (

= 0.44) and the interaction between the factors moment of post cutting and third root (

= 0.81) had no significant. The root third factor showed a significant effect (

= 0.01). The bond strength in the apical third was significantly lower than in the middle (

= 0.00) and coronal (

= 0.01) thirds.

The moment of post cutting has no effect on the bond strength of fiber posts fixed with self-adhesive cement to the root canal.

Erosive tooth wear has been a highly prevalent and emerging phenomenon related to eating habits of the population. Aim This study sought to investigate industrialized fruit juices exposure in enamel and dentine substrates in terms of erosive effect.

Human enamel and dentine specimens were randomized into 8 groups (n=8) Grape juice - Ades®, Grape juice - Del Valle Kapo®, Grape juice - Aurora®, Orange juice - Del Valle Kapo®, Orange juice - Ades®, Strawberry juice - Mais Vita®, Strawberry juice - Ades®, Citrus fruit juice - Tampico®. Specimens were submitted to an in vitro erosive challenge and to a microhardness test to evaluate the percentage of surface microhardness loss. The pH, titratable acidity, buffering capacity, degree of saturation and critical pH concerning hydroxyapatite and fluorapatite of the juices were measured as well as their composition of calcium, phosphate, fluoride, and total protein. Data were submitted to the analysis of variance and multivariate linear regression (α=0.05).

All test agents were undersaturated concerning hydroxyapatite and fluorapatite. A significant interaction between the type of juice and substrate was found (α=0.000, β=0.99). However, Orange juice - Del Valle Kapo®, Orange juice - Ades®, and Strawberry juice - Mais Vitta® demonstrated no difference between substrates. Grape juice - Ades® promoted less mineral than other juices in enamel and dentine. The calcium concentration in juices was a protective variable for microhardness loss in both substrates.

The erosive effect of industrialized fruit juices affects enamel differently from dentine, and this effect differed between some, but not all, tested juices.

Dental caries belong to a disease which has a complex etiology. Individual preventive measures are not adequate enough to control the disease especially in children with high caries experience The aim of the study was to evaluate the efficacy of tooth paste containing enzymes and proteins in inhibiting plaque re-growth when compared to fluoride tooth paste in children with high caries experience.

A total of 15 plaque samples are collected from 15 subjects in the age group of 5-7 years with High caries experience. The participants were asked to fast overnight for 12 h. On the day of the study, the participants were asked to report without brushing. Pre brushing pooled plaque was collected from buccal and palatal/lingual surfaces of maxillary and mandibular teeth and transferred to chilled Eppendorf tubes. Samples were divided into two groups; according to the test toothpaste used; Zendium toothpaste and Colgate cavity protection along with controls. Inhibition of plaque re-growth is assessed by comparing optical density using a spectrophotometer at intervals between 0-8 hours.

Results demonstrated that toothpaste containing enzymes and proteins can significantly inhibit plaque growth when compared to normal toothpaste (

<0.05) in children with high caries experience.

Toothpaste containing enzymes and proteins can augment natural salivary defenses and control plaque re-growth which plays a major role in dental caries formation.

Various procedures and techniques have been developed to increase the effectiveness and penetration of irrigants into the dentinal tubules and anatomical anfractuosities. Objective The purpose of this in vitro study was to compare the effect of different irrigation techniques such as conventional irrigation with a syringe, sonic activation irrigation with EDDY and Passive Ultrasonic Irrigation. All these on dentinal tubule penetration using Chlorhexidine.

45 lower premolar teeth extracted for orthodontic reasons were used. These teeth were decoronated to a length of 18mm. This working length was achieved by inserting a size 15 K file into the root canal until it was observed in the ápex. Then the length was reduced to 1 mm. The instrumentation was performed with the Wave One Gold system up to a file # 45. link2 Irrigated with 2mL of CHX between instruments. A final irrigation was performed using 5 mL of 17% EDTA with an E1 - Irrisonic insert for 30 seconds. Then, the root canal was irrigated with 5 mL of distilich the technique that showed the greatest penetration capacity was the ultrasonic activation. Key wordsClorhexidine. Dentinal tubule.

In restorative dentistry, the use of high-speed air turbine, which generates aerosols, can be associated with the transmission of airborne diseases. New laser technologies could be useful in reducing the amount of aerosols, but there is a lack of scientific research on this topic.

This is a descriptive study to analyze the amount of aerosols produced after class I cavity preparation using high-speed air turbine (group 1) and Er,CrYSGG laser with two different parameters (groups 2 and 3). Fluorescein dye was incorporated into the coolant reservoir in order to visualize the production of aerosols during each procedure. Tooth preparation was performed in a typodont with human lower molar tooth under rubber dam isolation. The procedure was carried out in a transparent plastic box to avoid aerosols dispersion. Sixteen grade I cellulose filter discs were distributed along the surfaces of the box. The area contaminated with aerosols in the filters was measured using ultraviolet illumination.

In group 1, the contaminated surface area covered with fluorescein dye reached 77.
