Multidisciplinary therapy is essential in dental practice to achieve optimized outcomes. The present case report describes the application of periodontal surgery with a five-year follow-up in a patient with malocclusion and chronic periodontitis. In the presence of periodontal inflammation, orthodontic therapy may result in further periodontal breakdown due to plaque accumulation. In order to prevent this progression, scaling and root planning with a periodontal endoscope was applied, and continuous clinical monitoring and risk assessment was performed every 3 months using a Florida Probe...

Dental hygienists are often faced with patients wearing lingual orthodontic therapy, as ultrasonic instrumentation (UI) is crucial for oral health. As the application of external forces can lead to premature bonding failure, the aim of this study was to evaluate the effect of UI on shear bond strength (SBS) and on adhesive remnant index (ARI) of different lingual orthodontic brackets. 200 bovine incisors were divided into 10 groups. Four different lingual (STB, Ormco; TTR, Rocky Mountain Orthodontics; Idea, Leone; 2D, Forestadent) and vestibular control (Victory, 3M) brackets were bonded...

Residual periodontal ligament (PDL) and cement mass on the roots of extracted teeth are factors that considerably affect tooth transplantation. Therefore, when normal extracted teeth are used for autologous transplantation, it is necessary to regenerate the PDL of the root surface. Here we describe a method to examine human PDL cell adhesion on sterilized root surfaces. Sample teeth were extracted during orthodontic treatment. PDL cells were obtained from healthy periodontal tissue explants from teeth extracted for orthodontic reasons...

The sustainability of the natural resources of our planet is a topic for worldwide debate. Mankind, during its evolution as a species, has not been greatly concerned about conserving the environment in which we live. Nowadays we are reaping the fruits of this neglect. Climatic changes and storms are good examples of this. We, humans, must re-think our attitudes in order to leave the planet in a healthy state to be used by our descendants. But thinking of orthodontics, what can we do as orthodontists? From this perspective, the authors of the present study aimed, in a clear and objective manner, to present simple and sustainable ways to proceed during our activity as orthodontists, in order to minimize the effects on nature, caused by man...

Introduction: Treatments with dental surgery seek to displace tooth to the correct position within the dental arch. Objective: To report a clinical case that took advantage of an unerupted third molar. Case history: A male patient, 18 years of age, was referred by his dentist to evaluate the third molars. The clinical exam revealed no visible lower third molars. The computed tomography (CT) exam showed the presence of a supernumerary tooth in the region of the mandibular ramus, on the left side, and impaction of the third molar, which was causing root resorption on the second molar, thus making it impossible to remain in the buccal cavity...
