Dental students using conventional chairs need immediate change in their posture. Implementing an ergonomic posture is necessary as they are at high risk for developing musculoskeletal disorders. This study recommends the use of an ergonomic seat and magnification system to enhance the visibility and the posture of an operator. The aim of this study is to make a foray into the hazards caused by inappropriate posture of dental students while working. It also aims at creating a cognizance about the related health implications among the dental fraternity at large, and to understand the significance of adopting an ergonomic posture since the beginning of the professional course. In the present study, postures have been assessed by using rapid upper limb assessment (RULA). This method uses diagrams of body postures and three scoring tables to evaluate ones exposure to risk factors. Ninety students from II BDS (preclinical students in the second year of dental school) were assessed in three groups using three different seats with and without magnification system. The results recorded significantly higher RULA scores for the conventional seats without using the magnification system compared to the SSC (Salli Saddle Chair-an ergonomic seat) with the use of magnification system. A poor ergonomic posture can make the dental students get habituated to the wrong working style which might lead to MSDs (Musculoskeletal diseases). It is advisable to acclimatize to good habits at the inception of the course, to prevent MSDs later in life.
Teens and adults experience thousands of injuries on the playing field, while biking and during other activities. Injuries to the face in nearly every sport can harm teeth, lips, cheeks and tongue. A properly fitted mouth protector is important to protect teeth and smile. This article gives a brief review on the mouth guards to be used to protect smile. KEY WORDS: mouth guard, mouth protector INTRODUCTION: Sports have the potential to seriously harm the head, face or mouth as a result of head-to-head contact , hazardous falls, tooth clenching or blow to the mouth. Knowing how to prevent injuries is important if you participate in organized sports or other recreational activities. When it comes to protecting your mouth, a mouth guard is an essential piece of athletic gear that should be part of an athlete's standard equipment from an early age. In fact, an athlete is 60 times more likely to suffer harm to the teeth when not wearing a mouth guard. Mouth guards help buffer an impact or blow that otherwise could cause broken teeth, jaw injuries or cuts to the lip, tongue or face. Mouth guards also may reduce the rate and severity of concussions. Sport, leisure and recreation activities are the most common cause of dental injuries. Dental injuries can be painful, disfiguring and expensive to treat. Dental injuries may result in time off work or school to recover, and lengthy (and expensive) dental treatment. A mouth guard, custom-fitted by your dentist and worn every time you play or train, will protect against dental injury. HISTORY: The exact origins of the mouth guard are unclear. Most evidence indicates that the concept of a mouth guard was initiated in the sport of boxing. Originally, boxers used to wear mouth guards out of cotton, tape, sponge, or small pieces of wood. They bite the material between their teeth. (1) These devices proved impractical, a British dentist, began to fabricate mouthpieces for boxers in 1892. Krause placed strips of a natural rubber resin, gutta-percha, over the maxillary incisors of boxers. (2) Philip Krause was an amateur boxer used his own device before 1921. (3) In the early 1900s, Jacob Marks created a custom fitted mouth guard in London. (4) In 1927 boxing match between Jack Sharkey and Mike McTigue. McTigue was winning for most of the fight, but a chipped tooth cut his lip, and he was forced to forfeit the match. From that point on, mouth guards were acceptable. (4,5) In 1947, a Los Angeles dentist, made a breakthrough by using transparent acrylic resin to form an "acrylic splint". In the 1948 issue of the Journal of the American Dental Association, the procedure for making and fitting the acrylic mouth guard was described in detail by Dr. Lilyquist. (6) He was awarded nationwide as the father of the modern mouth guard for athletes. (6,7) In the 1940s and 1950s, dental injuries were responsible for 24-50% of all injuries in American football. In 1952, Life magazine did a report on Notre Dame football players without incisors. (8) In the 1950s, the American Dental Association (ADA...
Skin is not the only place that can be decorated with a tattoo. You can decorate your tooth with amazing tattoos. Tooth tattoos and tooth jewels have become one of the hottest fashion trends, and a very popular arrival in cosmetic dentistry. But won't it be a boon if it had some preventive or medicinal value. Yes tooth tattoos can act as indicators of once illness. These tiny electronic sensors can diagnose illnesses by 'tasting' your breath. This paper is an insight into how a tooth tattoos can pick up early warning signs of sickness or infection by bacteria in people's breath.
Aim: To determine the effect of three different cavity disinfectants (2% chlorhexidine gluconate, 2.5% sodium hypochlorite, and 2% iodine solution) on microleakage in a seventh-generation dentin-bonding system. Materials and methods: Class V cavity was prepared on 50 extracted molars (n = 50). The respective experimental groups were treated with cavity disinfectants and Adper Easy One Bond. Preparations without cavity disinfectants worked as negative control and those with neither disinfectant nor dentin-bonding resin application worked as positive controls. After the cavity preparations were restored with resin composite (Filtek™ Z 350), the teeth were then subjected to dye leakage tests. Microleakage was assessed for both occlusal and gingival margins, using a stereomicroscope. Data were analyzed using (ANOVA; Kruskal-Wallis) test. Results: No statistically significant differences were observed among 2% chlorhexidine gluconate, 2.5% sodium hypochlorite, and 2% iodine and also no statistically significant differences were observed between occlusal and gingival margins of groups. Conclusion:(1) 2% chlorhexidine gluconate, 2.5% sodium hypochlorite, and 2% iodine produced significantly higher microleakage when used with seventh-generation dentin-bonding agent. (2) 2% chlorhexidine gluconate produced lesser microleakage in comparison with 2.5% sodium hypochlorite and 2% iodine. (3) The gingival margins exhibited greater microleakage than occlusal margins. Clinical significance: The application of cavity disinfectants on prepared tooth before the application of dentin-bonding agent could help to reduce the potential risk of residual caries and postoperative sensitivity.
