RESUMO
AIM: To investigate and compare the effect on compressive strength after incorporation of disinfecting solutions (sodium hypochlorite and povidone iodine) to commonly available type III dental stone. MATERIALS AND METHODS: A total of 90 dental stone samples of 20 × 40 mm were made. The standardized samples were fabricated according to the ADA specification no. 25 using custommade silicon mould and divided into 3 groups. Group A, type III gypsum was incorporated into distilled water; Group B, sodium hypochlorite (3%) was incorporated into distilled water in the ratio of 1:10 concentration according to ADA specification; and Group C, povidone iodine (3%) was incorporated into distilled water. The mix was carefully vibrated into the silicone mould and allowed to set. The specimens were subjected to compressive load after 1 and 24 h from the time of mixing using an Universal Instron testing machine. The result obtained were tabulated and subjected to statistical analysis using twoway analysis of variance tests. RESULTS: This study showed that incorporating the disinfecting solutions like sodium hypochlorite and povidone iodine decreases the compressive strength of type III dental stone. The effect of decreasing compressive strength on type III gypsum product is seen more in povidone iodine when compared to sodium hypochlorite disinfecting solution. CONCLUSION: Incorporation of sodium hypochlorite and povidone iodine disinfecting solutions is not an encouraging method as it reduces the compressive strength of type III gypsum product.
RESUMO
The use of the term "stem cells" dates back to the 1800s; however, the application of the same is still not completely understood. Recent advances have indicated the harvesting of postnatal stem cells from sources such as the dental pulp and fat. The pluripotent nature of these cells allows for use in various aspects of treatment and patient care such as organ and tissue transplantation, bony defects repair, distraction osteogenesis, cell therapies, gene therapy, and toxicology testing of new drugs. This article explores the various aspects involved, the current status, and future challenges of stem cell therapy in patient care and management.
RESUMO
OBJECTIVES: The objectives of this study were to evaluate the satisfaction of patients, parents, and individuals other than health professionals (neighbors or relatives), regarding the quality of care, and to evaluate the patients general care, facial appearance, dental changes, and psychological assessment by social outlook and emotional quotient. MATERIALS AND METHODS: Sixty patients with cleft lip and palate reporting to a dental institution were divided into two age groups, 0-15 years (G1) and 15-30 years (G2), their parents (P1 and P2) and a group comprising their neighbour's or relatives (T1 and T2) were also divided according to G1 and G2. To evaluate their satisfaction toward the treatment received, three separate questionnaires were given to the three groups and their responses were subjected to statistical analysis. RESULTS: The results showed that majority of patients (74%) and their parents (60%) were satisfied with the orthodontic treatment they received to align the teeth. But they were not satisfied with the appearance of lip (61.6% and 56.6%), nose (60% and 53.3%), and speech (62%). This study showed that cleft-affected individuals were teased mainly for speech (60%) followed by lip and teeth. Sixty percent of the patients admitted that their self-confidence was quite affected because of cleft and 36.6% expressed that their school/college results have been affected. CONCLUSION: Majority of cleft lip and palate patients as well as their parents were satisfied with their child's dental appearance; they were unsatisfied with the appearance of nose, lip, smile, and speech.
