In a society highly conscious of esthetics, prosthetic rehabilitation of lost teeth with tissue-integrated implants has gained wide acceptance and demand by patients and clinicians. The backbone of these tissue-integrated implants is the biotechnical process of osseointegration. Although the concept has been introduced and discussed for ages, the deepening knowledge about its cellular and molecular mechanisms has led the researchers to borrow further into the factors influencing the process of osseointegration. This has aided in the hastening and improving the process of osseointegration by exploiting several, even the minutest, details and events taking place in this natural process. Recently, due to the high esthetic expectations of the patients, the implants are being loaded immediately, which demands a high degree of implant stability. Implant stability, especially secondary stability, largely depends on bone formation and integration of implants to the osseous tissues. Various factors that influence the rate and success of osseointegration can either be categorized as those related to implant characteristics like the physical and chemical macro- and microdesign of implants or the bone characteristics like the amount and quality of bone and the local and systemic host conditions, or the time or protocol followed for the functional loading of the dental implant. To address the shortcomings in osseointegration due to any of the factors, it is mandatory that continuous and reliable monitoring of the status of osseointegration is done. This review attempts to encompass the mechanisms, factors affecting, and methods to assess osseointegration, followed by a discussion on the recent advances and future perspectives in dental implantology to enhance the process of osseointegration. The review was aimed at igniting the inquisitive minds to usher further the development of technology that enhances osseointegration.
Objective: The study aims to ascertain the prevalence and cause of low vision/ blindness in children of the rural population of the Indian states of Bihar and Jharkhand and justify the investment done on a population based survey for the particular age group. Material and Methods:The documentation of 1500 children was done with respect to their demographic data and ophthalmological examination. Results:The prevalence of childhood blindness was observed to be 0.2% with a predilection to female sex. The most common cause of visual impairment was uncorrected refractive error with incidences of blindness caused due to correctable condition of congenital cataract. Conclusion:Keeping in view of the life expectancy of 68 years in India, it can be reasonably stated that the number of years of visual impairment that can be shunned by these children oriented population based programs will have a significant impact on the burden being posed.
Little has been studied regarding the repeated usage of healing abutments and their effects on the distortion of dental implant-healing abutment hex surfaces. Additionally, implant manufacturers do not provide specific guidelines on how many times a healing abutment can be used before discarding. Therefore, we evaluated the effect of repeated screwing-unscrewing of implant-healing abutment on the healing abutment hex surface and screw head. A total of 12 Biomate implants with 4 mm diameter and 13 mm length were inserted into a synthetic bone block. The standard healing abutments of 3 mm diameter and 4 mm length were screwed onto each implant using a torque ratchet at a final torque of 30 Ncm. Immediately, the abutments were unscrewed at 30 Ncm. Then, screwing-unscrewing was repeated for 4, 8, 16, 24, 32, 40, 80, 160, 320, and 400 times and the healing abutments were scanned under the scanning electron microscope for any distortion. Distortion was graded as 0, 1, 2, and 3. Data were analyzed using SPSS 24.0. Descriptive statistics were calculated. One-way ANOVA with post hoc using Tukey’s HSD test was performed to analyze the difference in distortion at different screwing-unscrewing times. A significant level was selected at p-value = 0.05. It was found that distortion healing abutments screws were seen after 32 times screwing and unscrewing. There was a significant difference in the distortion (p-value < 0.05) after 24 times of repeated usage of healing abutment and at 160, 320, and 400 times. No surface distortions were observed at the healing abutment screw head at 4, 8, 16, 24, 32, 40, 80, 160, 320, and 400 cycles of screwing-unscrewing. It can be concluded that repeated screwing and unscrewing of the implant-healing abutments causes damage to the healing abutment hex surface. The distortion of healing abutments screws was seen after 32 times screwing and unscrewing. No surface distortions were observed on the healing abutment screw head until 400 times of screwing and unscrewing. Hence, the clinician should be cautious while using the healing abutments repeatedly.
A significant amount of empirical progress has been made in the management of pain over the last century,largely as a result of the introduction of a more effective pharmacological agent and the developmentof a better understanding of the principle of molecular development that governsits use. Much remains to be learned from the mechanisms and treatment of pain by researchers and practitioners. This review article will discuss regarding the important aspects of pain control in oral and maxillofacial facial surgery.
Yoga is a holistic approach to mental and physical health and is classified by the national institutes of health as a form of complementary and alternative medicine for human life. COVID 19 pandemic has impacted the quality of life of oral health care professionals. Our aim was to assess the effect of yoga on the quality of life of these professionals . Thirty participants (12 male/18 female) with a mean age 40.5 ± 2.5 years were prepared utilizing a 45-minute common yoga protocol module .All members went to 24 sessions over a 4-week regimen. A standard WHOQOL-BREF survey was utilized to evaluate the QOL in 4 areas (physical, psychological, social and environmental). The responses in terms of scores from the survey were investigated utilizing independent student 't' test. The change in the QOL following a 4-week yoga session was our studied outcome. After 4 weeks there was a significant change in physical domain (p=0.001), psychological domain (p=0.045) and in the total mean WHOQOL score (p=0.028).It was found that integrating yoga in daily curriculum does enhance the quality of life of oral healthcare professionals in the current COVID 19 Pandemic .
