The background of this novel study is how to apply an empirically adjusted Passive House concept in the tropics - beyond its otherwise prevailing global standards. Even though well-insulated houses have been on the planet since people settled down in some of their first dwellings, passive in the 21st century is different. It includes strict rules for airtightness and fitting of windows along with a sophisticated concept for artificial ventilation. Fresh air reachable from outside by filtered ventilation with heat recovery describes the heart of the system - if natural outside air is not prefer ..read more

Periodontal diseases are a consequence of the host’s inflammatory and immune mechanisms against dysbiotic bacterial plaque. Given the role of probiotics in biofilm control and modulation of dysbiosis, this study assessed the efficacy of a specific strain of Lactobacillus Reuteri, DSM 17938, in the treatment of stage II and III periodontitis. 36 patients were randomly allocated into two groups: group A, the treated group; and Group B, the control group. The treated group and the control group both underwent initial periodontal debridement. Patients received medications after unde ..read more

Background and objectives: Periodontal disease, as an inflammatory pathology, induces hemodynamic changes that can be evaluated by different unbiased methods such as laser Doppler flowmetry. This clinical investigation assesses laser Doppler as a non-invasive procedure to monitor gingival vascularization and its potential relationship with the response to treatment of periodontal disease.Materials & methods: 45 sites of white Spanish patients with active periodontitis undertake a complete periodontal analysis. This included periodontal pathogens identification along with the monitoring of ..read more

There is still limited information regarding patients’ perception of the dental approach changes in the pandemic circumstance. Therefore, the aims of this study were, firstly, to evaluate patient perception regarding the COVID-19 infection risk in the orthodontic office in Brazil, and to assess the influence of age in infection risk perception. Orthodontic patients from five states answered an online questionnaire, anonymously, about quarantine behavior, perception of the infection risk in the orthodontic office, as well as the apparent need for the new biosafety approach. Descriptive analyses ..read more

Stress, pain, injuries, and errors in dental procedures are situations highly linked to dentistry derived from multiple factors making this profession a profession with high physical and mental demand to achieve quality treatment without deteriorating the health of those who perform it, in this case, the dentist, the assistant, and hygienist.The effects of wrong postures, but above all, the lack of knowledge of the proper postures, the modeling of bad habits acquired during the training stage in dental school, and the lack of work guidelines that not only take into account the dentist but also ..read more

Aim: The aim of this study was to evaluate the oral hygiene status of patients with fixed mechanotherapy appliances.Methods and materials: The following indices were used to evaluate the oral hygiene status of patients in orthodontic treatment: Gingival Bleeding Index (GBI), Plaque index (PI) and OrthoPlaque Index (OPI) at three intervals.T0 (day 1), T1 (15 days), T2 (30 days) for a period of one month.Results: 10 patients (15-30 years old) were selected for the study from among the orthodontic patients treated at the Department of Orthodontics & Dentofacial Orthopedics, AIDSR, Adesh Unive ..read more

To reduce bleaching side effects, the use of low concentrations of Hydrogen Peroxide (HP) agents associated with hybrid light (violet LED/Diode Laser) has gained interest. Case report: The aim of this report is to describe a case of a 16-year-old patient that presented a complaint related to the color of his teeth and a maxillary midline diastema. In-office bleaching with 6% HP associated with hybrid light (violet LED/Diode Laser) was performed. The bleaching gel was applied once on the teeth and light-activated for 1 minute (15 times) followed by 1min intervals (15 times) with a total bl ..read more

Carbonic anhydrase VI (CA VI) catalyzes the reversible hydration of carbon dioxide in saliva with possible pH regulation, taste perception, and tooth formation effects. Objective: The aim of this work was to undertake a systematic review regarding the relationship between the expression/activity of CA VI in saliva and in dental biofilm and caries experience. Study design: Five databases were searched until February 2020. The composition was based on the PRISMA statement and on the PICOS model. First author, year, subject characteristics, analysis performed, outcome, measures & va ..read more

Posterior anchorage in the mandible has always been difficult to obtain during our orthodontic treatments. We tried a large number of screw anchors and plate systems which gave us quite acceptable clinical results but had many drawbacks ..read more
