Legislative framework addresses the issues of alloy corrosion, demanding the restricted use of probable carcinogenic, mutagenic, and toxic-for-human-reproduction (CMG) metals like nickel, cobalt, and chromium and demanding the development of new biomaterials. The aim of this research was to evaluate and compare the ion release of standard dental alloys and their hypoallergenic equivalents. Six types of orthodontic alloy wires (nickel–titanium (NiTi), coated NiTi, stainless steel (SS), Ni-free SS, and cobalt–chromium (CoCr) and titanium–molybdenum (TMA) were immersed into artificial saliva of pH 5.5 and 6.6. Release of metal ions was measured by inductively coupled plasma–mass spectrometry after 3, 7, 14 and 28 days. The data were analyzed using analysis of variance, and results with p < 0.05 were considered significant. NiTi released more Ti and Ni ions compared to the coated NiTi; SS released more iron, chromium, and nickel compared to the nickel-free SS. CoCr released cobalt in a high concentration and low amounts of chromium, nickel, and molybdenum compared to the molybdenum and titanium released by TMA. Release of metals from dental orthodontic alloys in vitro was overall lower at pH 6.6 and for the hypoallergenic equivalents when compared to standard dental alloys.

Today, legislative framework addresses the metal alloys’ corrosion issues, demanding the re-striction of use of the probable carcinogenic, mutagenic and toxic for reproduction at humans (CMG) metals, like nickel, cobalt and chromium, and demand to develop new biomaterials. Therefore, the aim of this research is to evaluate and compare ion release of standard dental alloys and their hypoallergenic equivalents. Six types of orthodontic alloy wires (nickel-titanium (NiTi), coated NiTi, stainless steel (SS), Ni-free SS, cobalt-chromium (CoCr), and titanium-molybdenum (TMA) were immersed into artificial saliva of pH 5.5 and 6.6. Release of metal ions was measured by inductively coupled plasma-mass-spectrometry (ICP-MS) after 3, 7, 14 and 28 days. Data analyses were done using analysis of variance, results with P

Introduction; Dental trauma can be defined as an injuryto the oral region including the lips, teeth, periodontal tissues, tongue and/or alveolar processes. The aims of management will depend on the age of the patient, type of tooth (primary or permanent) and the extent of the injuries. The treatment varies from preserving the tooth,extraction of the tooth and immediate implant placement. Immediate implantation is defined as placement of the implant into alveolus of the extracted teeth immediately after extraction. Materials and methods; A 45-year-old patient, suffered teethand dental bridge fracture and injury during car accident.Immediate teeth extraction was performed and immediate implantation with bone ridge preservation was performed, to rehabilitate the lost teeth. Patient underwent successfully for prosthetic rehabilitation 8 months after these procedures. Conclusion; Affected traumatized teeth often have areduced prognosis and, in some instances, may requireextraction. The majority of dental trauma is initially seenwithin a primary rather than secondary care setting. General dental practitioners should therefore be able to effectively manage the most common dental injuries, and to referthe complicated ones to oral surgeon. Dental implants are reliable to replace teeth lost because of traumatic dental injury. The timing of implant placement may be immediate,early, conventional, or late and is determined by the extent of the trauma, remaining growth, and conditions of the hardand soft tissues.

Background: Silver diamine fluoride (SDF) represents one of the most effective agents for the non-invasive management of dental caries, particularly in pediatric patients, where conventional treatment approaches often present significant challenges. The aim is to present our clinical experience in the non-invasive management of dental caries in preschool-aged children through the application of silver diamine fluoride (SDF) solution. Materials and Methods: This study involved 16 children, aged between 2 and 6 years, who were diagnosed with dental caries. All participants were managed using a non-invasive approach through the topical application of silver diamine fluoride (SDF) solution, aiming to arrest carious lesions and reduce the need for conventional restorative treatment, which can often be challenging in this age group. Results: All children were treated with a silver diamine fluoride (SDF) solution using a specialized applicator. In ten cases, the outcomes were highly satisfactory following the initial application. In five children, however, a second application was required after three months due to suboptimal results. Among these, only one child demonstrated insufficient improvement, necessitating a third application six months later. Conclusion: The findings of our study, consistent with those of numerous other investigations, unequivocally demonstrate that silver diamine fluoride (SDF) is a highly effective agent for both treating and preventing dental caries in preschool children. This success should instill confidence in the dental community about the potential of SDF in managing dental caries.
