RESUMEN
Background: Knowledge of bone density in maxilla and mandible will allow the clinician to plan the anchorage strategies and placement of implants with necessary precautions. The study aims to evaluate the deflection changes of titanium alloy self-drilling mini implants from the intended path that occurs during placement in varying bone densities. Material and Methods: 63 titanium alloy self-drilling mini implants of the lengths 6mm, 8mm, and 10mm with diameter of 1.3mm were placed in three homogenous solid rigid polyurethane foam (saw bone) with bone densities of 20pcf, 30pcf, and 40pcf simulating anatomic sites in maxilla and mandible. 7mini implants of each length in all bone densities were tested for study. The implants were inserted perpendicularly into artificial bone block held in a custom made stand. The bone blocks were then radiographically exposed and the deviation of the long axis of the implantfrom a true vertical line was measured. Results: There was a decrease in deflection of the mini implant with increase in density. On the other hand, increase in length resulted in increase in the amount of deflection. Conclusions: Longer mini implants can be used in less dense bone as in maxilla, whereas shorter mini implants can be used in high dense bone as in mandible to increase the stability and success rate of implants. Bone density and implant length play a role in deflection of mini implant from its intended path of insertion. Key words:Orthodontic Mini implants, deflection, bone density, anchorage.
RESUMEN
AIM: The increase in the technological development in dentistry has led to a better and efficient treatment being rendered to the patient. One such development is the application of laser in the field of dentistry. The introduction of laser has provided various advantages to the dentist. Therefore, a study was conducted to assess awareness among the dentists in Coimbatore district about the application of laser. MATERIALS AND METHODS: A cross-sectional study was conducted among the dentists in Coimbatore district. A questionnaire consisting of three parts was used to assess the knowledge, attitude, and practice of laser dentistry. RESULTS: The results were tabulated, and the percentages were statistically analyzed. The knowledge of laser usage and application of laser was present for almost 55% of the dentist. The attitude of dentist toward the advantage of laser was less. The practice of laser dentistry was poor among dentists, and only 10% were effectively practicing laser dentistry. CONCLUSION: The advantages of laser in daily dental practice are more advantageous than the disadvantages such as cost of equipment and material handling. Therefore, there is a great need for creating awareness of laser dentistry. Cost-effective equipment is the need of the hour to promote laser dentistry.
RESUMEN
AIM: To bridge the gap between urban and rural population, a vast number of researches are being carried out. Teledentistry is one of the technological advances in dentistry. It is defined by Cook in 1997 as "the practice of using video-conferencing technologies to diagnose and provide advice about treatment over a distance." This study aimed to assess the knowledge, attitude, and practice of teledentistry among general dentists in and around Coimbatore district, Tamil Nadu, India. MATERIALS AND METHODS: A self-administered closed-ended questionnaire was designed. The questions were divided into three sections based on knowledge, attitude, and practice. Data collected from the questionnaire were entered in Microsoft Excel. Level of significance (P < 0.05) was set at 95% confidence interval and P < 0.01 at 99% confidence interval was maintained, and the data were statistically analyzed. RESULTS: The majority of the dentists had less knowledge about teledentistry. About 73% of the dentists believe that teledentistry can provide access of specialists to the rural population. CONCLUSION: Of the dentists, 90% agree that teledentistry would be the major advancement in the future; however, there needs to be a specific module of operation and promotion of the module in future.
