Abordaje conservador y mínimamente invasivo de la hipomineralización molar-incisivo (HMI) - Relato de casos clínicos

Molar-Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Enamel defects may produce many symptoms that have physical, social and psychological effects and influence day-to-day living or quality of life. The available treatment modalities for teeth with MIH are extensive, ranging from prevention, restoration, to extraction. Factors such as age, patient expectations, severity of the lesion and materials should be considered in the treatment of the patient with MIH. Restoration with composite resin is an alternative choice for posterior and anterior MIH defective teeth and its use has been show acceptable results. This article describes two clinical cases involving pediatric patients with MIH whose procedure of cavity preparation was based on the use of CVD ultrasound diamond tips and restored using composite resin obtaining favorable esthetics results after a 1 year follow-up.

Redução do medo durante o tratamento odontológico utilizando pontas ultrassônicas

Over the last few years, new technologies have been developed to making cavity preparations, among which the diamond burs CVDentus® (CVDentus, São José dos Campos, Brazil) are outstanding. These points are produced by chemical deposition from the vapor phase, forming a single diamond stone, with greater durability than the conventional diamond burs. Coupled to the ultrasound appliance, they have several clinical applications in Dentistry with advantages over conventional rotary instruments, such as lower pressure, noise, vibration and heat, as well as reducing the need to use local anesthesia, contributing to minimize patient’s fear and anxiety. The aim of this study was to present the complete restorative dental treatment performed with this system in a child patient with a prior history of non-cooperative behavior. The use of this new technology offered the patient greater comfort, making it possible recondition the patient’s attitude to dental treatment, in addition to favoring conservative cavity preparations to be made.

Recobrimento radicular para o tratamento de hipersensibilidade dentinária cervical persistente

Gingival recession has a high prevalence in the population. This alteration may promote several complications such as cervical dentinal hypersensitivity (HSDC), carious and non-carious cervical lesions, and cosmetic changes due to the increase of the clinical crown length. To treat HSDC there are several therapeutic possibilities that should aim to eliminate pain after external stimulus. Treatment of this alteration can be performed by a conventional or invasive procedure, depending on the clinical condition and patients' desires. In situations where aesthetics is not the main complaint and HSDC persists even after conservative procedures, it is possible to indicate a procedure to achieve root coverage in Miller's Class I and II recessions. The aim of this paper is to report a case where the HSDC was not eliminated by conventional methods, which was resolved only after performing a minimally invasive surgery that promoted total root coverage.

Influência da clareação sobre a polpa dentária

Tooth bleaching is the most common treatment and more conservative to get a smile with white teeth. However, the tooth sensitivity has been a major adverse effects caused by this treatment, which raises questions about the effect of bleaching the pulp. Therefore, we performed a literature review in order to study the relationship between bleaching agents and their possible effects on the dental pulp. We review various articles showing that the peroxide compound used to whiten teeth, penetrates through enamel and dentin until the pulp chamber causing changes of variable intensity or induce pulp necrosis. Moreover, we found that the higher the concentration of peroxide in the bleaching agent, and the greater the contact time with this dental structure, the greater the damage caused in the pulp. Although several studies show that the bleaching agent hydrogen peroxide-based pulp can make changes, there are still many gaps to be filled.
