Alginate Dressings- Revisiting The Past, Oshine Jha, Oshine Jha

Annual Research Symposium

Wound healing in simple terms is the healing of skin which involves various mechanisms. It is not dressings themselves that heal wounds, but the careful selection of appropriate dressings that provide the optimal wound-healing environment for the individual wound. Wound dressings are prepared from biopolymers, synthetic polymers and biomaterials.

Silver Nano Particle Or Sodium Hypochlorite A Better Denture Cleanser, Dr.Tessa Kuriachan, Dr.Rahul Senan, Dr. Parvathy B, Dr. Keerthi Pt

Annual Research Symposium

Denture hygiene is compromised both due to the limitations of the denture base material as well as the lack of manual dexterity of denture wearers. Moreover, the rough tissue surface of the dentures affect the initial formation of candidal biofilms probably because it provides a greater surface area and protected sites for colonization. Among the various methods available to disinfect dentures, chemical method using Sodium hypochlorite seems to be the most effective one. Even though sodium hypochlorite is an effective denture cleanser,it has many disadvantages like the increased roughness of the denture surface and decreased colour stability. So a better …

Rapid Direct Wax Up For Provisional Crown Fabrication, Debra A. Woo Dds, Ma, Chi Tran

Pacific Journal of Health

While there are numerous choices for provisionalization, this technique is advantageous when a patient presents with an immediate need for temporization and there is limited time in the schedule for both the patient and provider. Providing an efficient solution using readily available materials that address the esthetics, function and reduction of sensitivity until the patient can be appointed for definitive treatment is illustrated.

Future Dental Journal

Background: Several treatment options are planned for completely edentulous patients rehabilitation which were developed to meet patients desires and requirements, starting from conventional complete denture till implant supported fixed full arch cases. Each technique has its own indication and limitations. Passive fit is an important factor for the long-term success of implant- prosthesis, which necessitate accurate transfer of the implant position. Recently, digital impressions have been introduced in dental implant treatment. By the use of scan body and different optical scanning methods, the position of scan bodies can be transferred to a virtual implant position within the dental arch. Material …

Shore A Hardness And Fourier Transform Infrared Spectrophotometer Analysis Of Thymol-Modified Maxillofacial Silicone Material, Manar Hussein Ramadhan, Faiza M. Abdul-Ameer

Maaen Journal for Medical Sciences

The longevity of any prosthesis depends on the materials from which it was fabricated, which is why defects in the material properties may reduce the service life of the prosthesis and necessitate its replacement. This study aims to test the influence of incorporating different weight percentages of thymol micro-powder into the maxillofacial silicone matrix on Shore A hardness of the silicone. Room-temperature vulcanised VST-50 maxillofacial silicone was used to prepare the study specimens. Thymol micro-powder was incorporated into the silicone matrix in two percentages (0.75 wt.% and 1 wt.%). 30 specimens were prepared and then subdivided equally into three groups, …

The Back Page Commentary: Let’S Talk About The Real World, Danielle Gehlert Dds

The Journal of the Michigan Dental Association

Dr. Danielle Gehlert, a private practitioner, writes that in the realm of continuing education for dental professionals, there's a need for a shift in focus from idealized, "sexy" cases to real-world patient scenarios. This commentary calls for seminars and programs emphasizing long-term restorative planning, including successes and failures. The practical considerations of patient financial limitations and willingness to engage in dental care must be integral to treatment plans. Real-world cases should reflect the diverse situations dental practitioners encounter and the ethical responsibility to provide affordable and effective treatment options.

Fabrication And Characterization Of Nylon 6 Fiber Via Wet Spinning Method For Application As A Reinforcing Material For A Direct Dental Bridge, Dissa Kirana Wijaya, Nina Djustiana, Yanwar Faza, Arief Cahyanto, Andri Hardiansyah

Makara Journal of Science

Nylon is a biocompatible thermoplastic polymer that is well known for its excellent fracture resistance, making it suitable for fabricating fiber-reinforced composite (FRC)-based dental bridges. FRC is widely used in dentistry. This study aimed to investigate the structural and morphological characteristics of the nylon 6 fiber prepared using five different weights of nylon 6 dissolved in formic acid. The nylon 6 fiber was successfully fabricated via a simple wet spinning method using water as a coagulant. The fiber was then characterized using Fourier transform infrared (FTIR) spectroscopy, optical microscopy, and scanning electron microscopy. FTIR spectroscopy confirmed the presence of nylon …

Impacts Of A Duf2207 Family Protein On Streptococcus Mutans Stress Tolerance Responses And Biofilm Formation, Xiaochang Huang, Camile G. Laird, Paul P. Riley, Zezhang Tom Wen

School of Dentistry Faculty Publications

Locus SMU.243 in Streptococcus mutans was annotated as a member of the DUF2207 family proteins highly conserved in all bacteria but with unknown function. To investigate its role in S. mutans physiology, a SMU.243-deficient mutant was constructed using allelic exchange mutagenesis, and the impacts of SMU.243 deletion on bacterial growth, stress tolerance response, and biofilm formation were analyzed. Compared to the wild-type UA159, S. mutans lacking SMU.243 displayed a reduced growth rate and a reduced overnight culture density (p < 0.01) when grown at low pH and in the presence of methyl viologen. Relative to the parent strain, the deficient mutant also had a reduced survival rate following incubation in a buffer of pH 2.8 (p < 0.01) and in a buffer containing hydrogen peroxide at 58 mM after 60 min (p < 0.001) and had a reduced capacity in biofilm formation especially in the presence of sucrose (p < 0.01). To study any ensuing functional/phenotypical links between SMU.243 and uppP, which is located immediately downstream of SMU.243 and encodes an undecaprenyl pyrophosphate phosphatase involved in recycling of carrier lipid undecaprenyl phosphate, a uppP deficient mutant was generated using allelic exchange mutagenesis. Unlike the SMU.243 mutant, deletion of uppP affected cell envelope biogenesis and caused major increases in susceptibility to bacitracin. In addition, two variant morphological mutants, one forming rough colonies and the other forming mucoid, smooth colonies, also emerged following the deletion of uppP. The results suggest that the SMU.243-encoded protein of the DUF2207 family in S. mutans plays an important role in stress tolerance response and biofilm formation, but unlike the downstream uppP, does not seem to be involved in cell envelope biogenesis, although the exact roles in S. mutans’ physiology awaits further investigation.
