The present work aims to carry out modal analysis of a functionally graded material (FGM) plate to determine its natural frequencies and mode shapes by using Finite Element Method (FEM). For this purpose, a code was written in MATLAB and linked with ABAQUS. First, a simulation was performed in accordance to other researcher’s model, and then after comparing the obtained results, the accuracy of the present study was verified. The obtained results for natural frequency and mode shapes indicate good performance of user-written subroutine as well as FEM model used in present study. After verification of obtained results, the effect of clamping condition and the material type (i.e., the parameter n) was investigated. In this respect, finite element analysis was carried out in fully clamped condition for different values of n. The results indicate that the natural frequency decreases with increase of n, since with increase of n, the amount of ceramic phase in FGM plate decreases, while the amount of metal phase increases, leading to decrease of the plate stiffness and hence, natural frequency, as the Young modulus of Al2O3 is equal to 380 GPa and the Young modulus of SUS304 is equal to 207 GPa.

The treatment of complicated crown-root fractures of tooth is often compromised by a fracture apical to the gingival margin and/or bone. This makes isolation difficult and compromises the adhesive union which is critical for a successful treatment. In the present case, the fracture line extended from cervical third of labial surface to cervical third of palatal surface sub gingivally which made the case a complicated crown root fracture. The reattachment of fragments would bring the vulnerable joint in the primary stress bearing area and in the subgingival region. Hence the tooth was removed traumatically with the help of periotome and intentional replantation was done which facilitated the attachment of fragments extra orally. Fragments reattachment was reinforced with the intraradicular fiber post and glass ionomer cement. Then the tooth was rotated 1800 to bring the subgingival fracture line to the labial surface where the occlusal load is less. As the amount of extra oral time is a critical factor in the success of reimplantation, the procedure was completed in 20 minutes. The teeth were stabilized with semi rigid splint for 6 weeks. Later full veneer crown was cemented on the tooth. The patient was followed up with clinical examination for mobility test, gingival sulcus depth and radiographic analysis to analyze the integrity of root, the alveolar cortex and the periodontal space for 12 months. The treatment is successful so far and has rendered satisfaction to both the clinician and patient.

Binder-jet 3D printing responses of sea-shell powder based ceramic composites have been evaluated considering the material consolidation mechanisms and mechanical characterisations. Initial experimental printing trials are done manually, varying the composition of the composite powders from 5% to 50% of the seashell powder and the rest plaster. Overall, the seashell and plaster combinations worked well in terms of achieving the necessary green strengths within the binder-jet process conditions. Scanning electron microscopy and 3-point bending results indicated no significant loss of properties at lower levels of the seashell component, but the strength decreased beyond the 25% mark. The optimum levels of seashell powder are found to be within 15-20% by weight in terms of the best compression strengths. Neat sea-shell powder however goes too sticky immediately after the interaction with the binder liquid and does not show evidence of any binding mechanism that can be accelerated.

Bone tissue engineering, using a synthetic porous scaffold material provides some distinct advantages over autografting and allografting, and it is a rapidly growing alternative approach to heal damaged bone tissue. The current study focuses on fabrication and characterization of nano β-TCP incorporated gelatin- chitosan based composite scaffold for bone regeneration at the sites of musculoskeletal defects and disorders. Gelatin-chitosan scaffold reinforced with beta-tricalcium phosphate (β-TCP) nanopowder was fabricated through freeze drying of material’s suspension. From powder X-ray diffraction and Fourier transform infrared spectrometer analysis the presence of phase pure β-TCP powders in gelatin-chitosan matrix was confirmed. Gelatin-Chitosan-β- TCP (GCT) scaffold exhibited a homogenouos porous structure with an average pore size of 118 ± 11 μm. Micro-CT image confirmed interconnected porous network with homogeneous distribution of β-TCP nanoparticles in Gelatin- Chitosan (GC) matrix. GCT scaffold showed higher compressive strength of 2.45 ± 0.15 MPa as compared to 1 MPa exhibited by neat GC scaffold. Protein adsorption capacity was increased to 22 mg/cc in GCT scaffold from 13 mg/ cc in GC scaffold. Weight loss of GCT scaffold was lower of 26% as compared to 47% in GC scaffold after 8 weeks of incubation in phosphate buffer solution of pH 7.4. Mesenchymal stem cells cultured onto GCT scaffold exhibited higher degree of lamellipodia and filopodia extensions and greater spreading onto GCT scaffold as compared to that in GC scaffold after 7 and 14 days of culture. MTT assay suggested higher degree of proliferation of MSCs cultured onto GCT scaffold as compared to that onto pure GC scaffolds. This study demonstrates that β-TCP incorporation into gelatin- chitosan matrix improved osteogenic potential of the scaffold suitable for bone tissue engineering

Some phosphate glasses containing different amounts of by-pass cement dust (BCD) were prepared by the melt quenching method. The selected molecular composition was [(100-x)% - P2O5 (x)% BCD (where 30≤ x≥60)]. The obtained experimental density and molar volume values were inspected and were then compared with those obtained empirically for the close packed structure of the corresponding compounds. The comparison between experimental and emperical values evidenced the short range order of the studied samples. The electric and dielectric properties were thoroughly investigated. The appearance of maxima and minima in the total conductivity BCD concentration dependence can be attributed to the mixed alkali – alkaline earth effect (MAAE) and to the presence of considerable amount of CaO. The suitability of such glasses to act as gamma-ray shielding materials was thoroughly investigated, and correlation between the chemical composition (the BCD concentration) and gamma-ray attenuation behavior was established.

It’s been over 25 years since Professor Larry Hench published his seminal article entitled “Bioceramics: From Concept to Clinic”[1] and more than 40 years since he first reported the peculiar bioactive properties of glass compositions within the Na2O-CaO-P2O5-SiO2 quaternary system [2]. Curiously, the investigative ideas which led him to develop Bioglass® did not have their origin in the laboratory. They were born from the clinical need to heal the horrible wounds incurred by servicemen returning from the Vietnam War. Indeed, after a conversation with a ranking army officer, his work began under a simple hypothesis:

The antimicrobial effect of staphylococcus aureus, Streptococcus mutans, E. coli and Candida albicans are dependent on surface properties and restorative dental materials types. The aim of this study was to evaluate the effect of antibiotics on the residual natural saliva (after Filtek, glass-ionomer, porcelain and zirconia takeout from it). Also, the effect of brushing on fungi and bacteria growth in these surface materials was characterized. The results show that, bacterial growth around Filtek, glass ionomer, porcelain, and zirconia materials after takeout from saliva that is meant these materials have no resistance for E. coli, staphylococcus aureus, Streptococcus mutans and Candida albicans. The color of residual saliva changed. All antibiotics caused inhabitation zone except Ampicillin. Ciprofloxacin shows significant inhibition zone for all used materials. Also, brushing removed most if not all fungi and bacteria formed on surface dental materials.

The use of ceramic materials in the field of biomaterials is rapidly expanding. Biomaterials are a preferred market for ceramics due to their chemical inertia and high hardness, compared to traditional metals. (Inlays, onlays, crowns, bridges, periodontal rings, brackets, implants, etc.). The main applications are orthopedic surgery (artificial joints, bioactive layers for better osseointegration) Seals for pacemakers, defibrillators, neurological stimulators, cochlear implants, etc.). In several cases, ceramic materials replace metallic alloys whose use induce, if poorly controlled, serious environmental problems (Cobalt /Chrome alloy, amalgam lead/Mercury/tin for the dental care, etc.). The metals making up these alloys lead to very serious environmental stresses due to their high toxicity [1-5].
