“…Table 5 summarizes the major mechanical features of a tooth [5,[54][55][56][57][58]. In general, the tooth mechanical properties are dependent on the patient's age [57,59,60]; therefore, the choice of one particular material for dental applications rather than another one should ideally be done by taking into account this parameter.…”

“…Table 5. Mechanical properties of a natural tooth (data from [5,[54][55][56][57][58] Natural enamel and dentine exhibit unique characteristics and, at present, an ideal material able to match all their mechanical properties (strength, stiffness, toughness, hardness) does not exist. From this viewpoint, the glass-ceramics proposed in this work also have some limitations, but they exhibit interesting advantages compared to the majority of dental glass-ceramics commonly proposed in the literature [24].…”

Abstract:Multicomponent silicate glasses and their corresponding glass-ceramic derivatives were prepared and tested for potential applications in dentistry. The glasses were produced via a melting-quenching process, ground and sieved to obtain fine-grained powders that were pressed in the form of small cylinders and thermally treated to obtain sintered glass-ceramic samples. X-ray diffraction investigations were carried out on the materials before and after sintering to detect the presence of crystalline phases. Thermal analyses, mechanical characterizations (assessment of bending strength, Young's modulus, Vickers hardness, fracture toughness), and in vitro bioactivity tests in simulated body fluid were performed. On the basis of the acquired results, different potential applications in the dental field were discussed for the proposed glass-ceramics. The use of such materials can be suggested for either restorative dentistry or dental implantology, mainly depending on their peculiar bioactive and mechanical properties. At the end of the work, the feasibility of a novel full-ceramic bilayered implant was explored and discussed. This implant, comprising a highly bioactive layer expected to promote osteointegration and another one mimicking the features of tooth enamel, can have an interesting potential for whole tooth substitution.

“…Hipomineralizasyonun olduğu bölgelerde, mine yü-zeyi başlangıçta normal kalınlığında gelişme-sine rağmen mineralizasyonun bozuk olmasın-dan dolayı yumuşak ve pöröz yapıdadır (1,2). Bu nedenle mine tabakası sürme sonrası çiğ-neme kuvvetleri altında kolaylıkla aşınmakta ve kırılmakta (1,4,5), açığa çıkan dentinde hızlı bir şekilde çürük gelişmekte (5) ve atipik kaviteler oluşabilmektedir (6,7).…”

Aim: The purpose of this pilot study is to comparative evaluation of the clinical effectiveness of direct and indirect composite resin restorations in hypomineralized first permanent molars. Materials-Methods:A total of 20 hypomineralized first permanent molars in 10 children aged 7-11 were included for the study. Teeth were randomly divided into two groups according to the restoration type to be applied: direct or indirect composite resin restorations. Restored teeth were clinically evaluated at baseline, 6 and 12 months by modified United States Public Health Service (USPHS) criteria. Mann-Whitney U and Friedmann tests were used for statistical analysis of data.Results: During the 12-month follow-up period, although Alpha and Bravo scores were determined, no Charlie score was observed in both direct and indirect resin restoration groups. According to USPHS criteria scores, for each group, no significant difference was observed between follow-up periods (p>0.05). When the clinical success of direct and indirect composite resin restorations were compared, the scores of marginal adaptation, marginal discoloration and anatomical form of indirect composite resin restorations were observed to be better than direct composite resin restorations; however, this difference was not statistically significant (p>0.05).

“…[16] Furthermore, there appears to be a transition zone between hypomineralized defect and sound cervical enamel. [17] The hardness and modulus of elasticity of cervical enamel are similar to sound enamel making this region useful for bonding of restorative material to the affected tooth with resin composite as adhesion in hypomineralized region may be compromised [ Table 2]. …”

Molar incisor hypomineralization (MIH) is a congenital disease which is increasing in prevalence. It affects permanent first molars and, often to a lesser degree, permanent incisors with variable severity. The etiology is unknown, but various risk factors have been put forward. Differential diagnosis is mandatory not to confound MIH with other diseases such as amelogenesis imperfecta or fluorosis. Treatment consists in a minimally invasive approach by reinforcing and protecting the existing dental structure. In more severe cases, restorative treatment or extraction may be indicated.
