(Geneva Foundation, 2024-01) Carvalho, Lais Morandini; Vasconcellos, Luana Marotta Reis de; Zutin, Elis Andrade Lima; Sartori, Elisa Mattias; Mendonca, Daniela Baccelli Silveira; Mendonca, Gustavo; Carvalho, Yasmin Rodarte
Studies have been directed towards the production of new titanium alloys, aiming replacement of TiAlV alloy in the future. Therefore, many mechanisms related to biocompatibility and chemical characteristics have been studied in the field of implantology, but until now, enzyme defenses against oxidative stress have been underexplored. The objective of this study was to evaluate the activity of the antioxidant enzymes Superoxide Dismutase (SOD) and Catalase (CAT) in porous scaffolds of Ti-6 Aluminium-4 Vanadium, Ti-35 Niobium and Ti-35 Niobium-7 Zirconium-5 Tantalum. Porous titanium alloy scaffolds were prepared by powder metallurgy. Mesenchymal stem cells from mouse femur were used. After 24 hours the cells plated under the scaffolds were analyzed by Scanning Electron Microscopy (SEM). The antioxidant enzymes activity was measured after 72 hours of cell plating and after 3,7 and 14-days, cells were collected to evaluate RUNX2 expression by real-time PCR. The SEM images showed the presence of interconnected pores and growth, adhesion and cell spread in the 3 scaffolds. Our results for SOD and CAT were shown to be better for the TiNbZrTa and TiAlV scaffolds. The TiNb scaffold presented less activity for both enzymes. Despite differences between the scaffolds, there were not any statistical differences (p>0.05). RUNX2 presented high expression for TiNbZrTa and TiAlV at day 7 and presented statistical differences just for TiNbZrTa from the control group (TiAlV day 3). At day 14, all scaffolds showed expression above the baseline and exhibited statistical differences from the control group. It was possible to conclude that, as regards antioxidant enzymes, we are not able to confirm any differences which would justify the replacement of TiAlV, but gene expression showed a better capacity for mesenchymal stem cell differentiation in TiNbZrTa, making it a good choice for biomedical applications.

Supernumerary Teeth: An Overview
(Longdom Publishing SL, 2017-12) Patil, Anil Kumar
Supernumerary teeth (SNT) are extra teeth to the normal complement of teeth in both dentitions. These SNT could be appear in any region of both jaws. Males are commonly affected by SNT than the females. Most commonly seen SNT are mesiodens, very rarely seen SNT are distomolars. Identification and localization of SNT are very important for diagnosis and management. SNT may cause various complications that include delayed or impaired eruption of adjacent teeth to cyst formation, and eruption into nasal cavity. Hence, the early identification and appropriate management is essential to prevent the possible complications.
Influence of storage temperature on vickers microhardness of resin composite
(Longdom Publishing SL, 2018-12) Almozainy, Mayyadah
Introduction: The purpose of this study is to evaluate the effect of three storage temperatures on microhardness of high and low viscosity bulk-fill materials and compare them with conventional resin-based composite materials. Materials and method: Six composite resin-based materials were used in this study (TN, TNB, TNF, FZ250, FB and FBF) samples were subdivided into three groups based on the pre-curing storage temperature (5°C, 23°C and 37°C). Light polymerization for each material was performed based on the manufacturer’s recommendation using Bluephase G2 curing unit (Ivoclar Vivadent, Schaan, Liechtenstein) in a high-intensity mode with an irradiance of 1200 mW/cm2. Vickers hardness values of top and the bottom surfaces of each sample were evaluated using (NOVA 130 series, Vickers and Knoop hardness testing instrument) under a 200 g load with a dwell time of 10 sec. Also three indentations with the random distance of 1 mm were taken from the top and the bottom surfaces of each sample and a mean Vickers hardness (VHN) value were calculated (n=18 top and n=18 bottom). The mean bottom/top ratio was calculated by dividing VHN of the bottom surface by VHN of the top surface. Results: When the tested materials were stored at room temperature (23°C) before testing in the present study, they failed to reach the minimum 80% of the mean bottom to top hardness value ratio except for FZ250 and FBF, where they reached 97.8% and 83.2% respectively. Where in samples that were stored refrigerated at 5°C all the materials have reached the minimum 80% of the mean bottom to top hardness value ratio except for FBF (77.3%) and TB (77.2%). On the other hand, the only material that reached the minimum 80% of the mean bottom to top hardness value ratio when the materials were stored at 37°C was FZ250 (93.5%). Conclusion: Despite the promising results from this preliminary study, regarding improvement of microhardness with refrigerated composite resins, further research has to be conducted. The enhancement of hardness values associated with preheated composites could be beneficial in countries with warm climate such as Saudi Arabia. The association of precooled composite resin and the use of the LED curing units could be recommended to improve resin-based composite hardness. Further research is needed to evaluate the other mechanical properties and whether or not they are influenced by storage temperature.

(Longdom Publishing SL, 2017-12) K, Sudha; K, Hanisha Reddy; O, Seema Reddy; Ch, Laxmana Rao; T, Leela Naga Pavani; P, Sravana Laxmi
Aim: The purpose of this study was to compare the influence of different polishing systems on the surface roughness of nano-hybrid composite resins. Materials and Methods: Fourty samples of acrylic blocks were prepared with cold cure acrylic resin in plastic rings of 1 inch diameter. In each acrylic block, a well of 6mm diameter and 2mm depth was prepared by drilling hole in it using a slow speed micromotor. Tetric N-Ceram™ nano composite is placed in the wells prepared using a plastic instrument and covered with a mylar strip. The samples were then cured for 40s through the mylar strips using LED curing light. 60 samples were divided into 4 groups with 15 samples in each group based on polishing regimen used. Group A - Mylar strip, Group B- PoGo diamond polishers, Group C- prophy brushes and Group D- Super- Snap Rainbow kit. The polished resin composite discs were washed, allowed to dry and kept again in 100% humidity for 24 h before measuring the average surface roughness values (Ra). The surface roughness test was performed using a profilometer and surfaces are seen under scanning electron microscope[SEM]. Statistical analysis: The data were analysed by using one-way ANOVA using SPSS 17.0 software. Results: For all the materials, the smoothest surface was obtained with mylar strip and the roughest with prophy brushes(P< 0.05).Conclusion: Mylar strip produced smoothest surface than other polishing systems.
Stress Related Oral Disorders: An Update
(Longdom Publishing SL, 2017-12) Rai, Arpita; Kumar, Ansul
Oral changes with psychosomatic etiology are still an insufficiently confirmed and investigated subgroup of psychosomatic diseases which have long been known in medicine. In their daily practice dentists frequently come across patients showing signs of stress and their oral manifestations in form of recurrent oral stomatitis, oral lichen planus and temporomandibular disorders. Recognition of such psychological or emotional disturbance benefits both the patient and clinician. Hence psychological management should be taken into consideration when treating patients with these psychosomatic disorders.

(Longdom Publishing SL, 2017-09) Anand, Preetha; Deepthi, Mandava; Yelamanchi, Ravishankar Babu
Ectodermal dysplasia’s are inherited diseases that have developmental defects in at least two major structures derived from the ectoderm. The most characteristic findings are sparse scalp and body hair, reduced number of sweat glands, heat intolerance and brittle nails. Some infants and children have premature look referred to as an ‘old man’ facies. Characteristic dental findings include hypodontia, abnormal shaped teeth, delayed teething. Early dental treatment promotes self confidence improves individuals psychosocial condition. The parents must be educated and motivated about the importance of dental treatment in such patients. The present case is a report of 6 year old boy having defects in all the Ectodermal derivatives with significant dental findings wherein the patient’s mother was reluctant to accept the proposed treatment plan. Hence we felt that parental motivation is a prerequisite in such cases.

(Longdom Publishing SL, 2017-09) Kotnala, Pragya; Rahangdale, Tripty; Noorani, Syed M; Jain, Nimit; Nayak, Karvika
The fracture of complete dentures constitutes a challenge and remains an unresolved problem. A midline fracture of single maxillary complete denture base especially in patients who have retained their natural mandibular teeth is an inevitable problem. Several factors have been attributed for the midline fracture including flexural fatigue resulting from cyclic deformation and those which exacerbate the deformation of the base or alter its stress. The present case report deals with oral rehabilitation of completely edentulous maxillary arch by incorporating metal denture base in place of the conventional Poly Methyl Methacrylate material to improve the longevity of the prosthetic replacement, at the same time prevent resorption of the underlying residual maxillary ridge.

Introduction: The internet, one of the important scientific developments in this field, provides a wealth of information in relation to diseases, therapeutic procedures and pharmaceutical products. It has a lower cost as compared to paper based dissemination of information and also has an added advantage of being available worldwide instantly on demand. Therefore, there is a need not only to equip Dental fraternity with adequate skills for use of internet but also to make internet facility available in institutions providing Dental education and healthcare. Aim: The aim of this study is to find out the use of computers and internet and the purpose of using the internet among undergraduate and postgraduate dental students and faculty members compare male to female ratio of using internet. Materials and Methods: Internet addiction questionnaire consisting of 20 questions were distributed among the Dental Undergraduate and postgraduate students and faculty members. No specific sampling technique was employed for selecting the study subjects. Data was analyzed using EpiInfo. Chi-square test was used to find out statistical significance of differences in proportions. A p-value of <0.05 was considered to be significant. Results: As per the results the male dental students uses internet more than female dental students doing extracurricular activities besides educational work. The productivity and work performance of male dental students suffer more than female students due to prolonged internet use. Male dental students also hide their online time and become more defensive and secretive when someone bothers them online. So almost 50 % are at the verge of internet addiction and they have to be monitored properly.

Preventive Prosthodontics: Overdenture With Ceka Attachment: A Case Report
(Longdom Publishing SL, 2017-09) Nayak, Karvika; Rahangdale, Tripty; Shrivastava, Sourabh; Kotnala, Pragya
Functional stability and the preservation of remaining alveolar bone are primary, and often elusive, goals when restoring the partially edentulous arch. Conventional complete denture wearers experience a number of problem such as instability of the mandibular dentures, inability to masticate food. Overdenture increases the retention , improves support, preserve the alveolar bone by decreasing the rate of resorption and improves the masticatory efficiency resulting in improved quality of life and oral health. The teeth which are preserved play a vital role by improvement of crown root ratio, provide proprioception. Rehabilitation using over dentures is a widely accepted preventive approach due to its ease of fabrication and the successful prognosis. This clinical report describes a multidisciplinary approach for complete oral rehabilitation of a patient with two remaining natural teeth using precision attachment (ceka Preci‑Clix Radicular RC) for mandibular overdenture and conventional overdenture.
