ABSTRACT
Objective: The objective of this study was to adapt the Oral Health-related Early Childhood Quality of Life (OH-ECQoL) tool for the Malayalam-speaking community and investigate its validity and reliability. Methodology: Malayalam language version of OH-ECQoL was derived through a forward–backward translation and tested for content validity. A convenient sample (n = 300) was recruited by including children with and without early childhood caries (ECC). Parents of these children completed the derived Malayalam OH-ECQoL measure. The properties of translated OH-ECQoL were evaluated by determining its validity and reliability using concurrent validity, construct validity, discriminant validity, internal consistency, and test–retest reliability. Results: OH-ECQoL scores varied with ECC and caries-free groups (P < 0.001), supporting the ability to distinguish between patient groups. Discriminant validity tests show that children with ECC have greater median scores and interquartile range (21 ± 8) compared to children without ECC (14 ± 2). Concurrent validity was observed to be 0.72 and 0.71, respectively, for child section (P < 0.001). Convergent validity demonstrates a strong positive correlation between child impact and family impact with a Spearman's correlation coefficient significant of 0.73 (P ? 0.01). Cronbach's alpha for the child impact section and family impact section showed good internal consistency at 0.92 and 0.83, respectively. Test–retest reliability at 0.87 shows good reliability. Conclusions: The Malayalam version of the OH-ECQoL tool demonstrated acceptable validity and reliability. The study also shows that ECC presents a negative impact on the QoL of preschool children and their parents.
ABSTRACT
Objectives: From the time composite has been developed, it has been subjected to various changes in composition like addition of filler and initiators to yield better result. One such modification is the new bulk fill composite. However an acceptable polymerization time to maintain adequate curing depth has to be evaluated. So the aim of this in vitro study was to evaluate the effect of polymerization time on curing depth of four bulk fill flowable composites. Methods: Total of 80 cylindrical specimens were prepared, and divided into 4 groups comprising of 20 specimens in each group. These selected groups were again subdivided into 4 groups comprising of 5 specimens in each group, based on their polymerisation time. The four specimens were Group A: SDR flow (DENTSPLY), Group B: Tetric N' Flow (Ivoclar Vivadent), Group C: Filtek bulk fill (3M) and Group D: Venus bulk fill (Heraeus Kulzer).The aluminium mold of 4mm depth and 5mm diameter was filled with composite and top surface was irradiated using Valo LED curing light with polymerisation time of 10, 20, 40, and 60seconds on respective subgroup.The microhardness of top and bottom surfaces were performed using Vickers Hardness tester under the load of 200gram for 15seconds. The depth of cure of each specimen was determined by hardness ratio method using the formula Hardness ratio=VK of bottom surface/VK of top surface.The results were statistically analysed. Results: The study results showed that all the tested bulkfill composites can be cured to an acceptable depth. Tetric N' Flow exhibits maximum curing depth (95.28 ±0.26) at 10sec polymerisation time. Venus bulk fill showed higher depth of cure at 20 and 40sec curing time (96.79±0.39 and 97.56±0.20). SDR flow showed adequate curing depth at 20 and 40sec curing time (92.94±0.49and 93.62±0.22 respectively). Filtek bulk fill has maximum depth of cure at 40sec curing (89.10±0.79). Conclusion: Increasing polymerisation time increases the top as well as bottom micro-hardness of all tested bulk fill composites. Tetric N' Flow maximum curing depth at 10sec curing time. Filtek bulk fill is the material with least depth of cure.
ABSTRACT
Dental caries is the most common chronic disease affecting the children today. Many dental problems can be effectively prevented in children if they are detected early. Medical practitioners play a major role in the primary care of the child and are well positioned to recognize potential problems, encourage preventive care and refer appropriately. So the present survey was conducted among Medical practitioners in Kannur, Kerala to determine their knowledge, attitude and practice in Pediatric preventive dental care.o assess the attitude and practice of dental professionals towards using of advance Radiographic technique.
ABSTRACT
In the past, cases with open apices were often treated over several appointments, using calcium hydroxide, with the hope of creating a ''calcific'' barrier against which gutta percha could eventually be placed. The treatment could be as long and the prognosis is questionable. These roots were often thinner and, therefore, more brittle; extending treatment over a long period of time without providing a permanent restoration increased the chances of losing these teeth due to fracture. With the favorable histologic response of MTA, this material is the best current choice for this procedure. Completion of these cases in an effective and efficient way allows for permanent restorations to be done in a timelier manner, prolonging the longevity of these teeth. The following case report demonstrates the use of MTA as an obturating material to promote periapical healing with an open apex.

Historically, Indian education has been elitist. Currently, India has the second largest education system in the world preceded by China. In order to meet the demand for coveted dental education, private dental colleges have sprung across the country, making the access easy for the students to enroll into dental education programmes after their higher secondary education. This has lead to a suspicion whether these dental students had been forced into a course that they did not aspire of and even if they actually chose the career, are they performing as good as they expected to be once the course commences. This questionnaire survey aims at discussing these issues and to prepare the Indian education system at both school and college level to encompass and implement an orientation and motivation program to overcome this.

Mesiodens are considered as one of the most common supernumerary teeth. The main objective of the study was to determine the prevalence rate of mesiodens in the school going children between the age group of 6-14 years The study shows a prevalence rate of 0.7% with sex ratio of 2:1 favouring males.

AIM: This study was carried out to estimate the concentrations three microelements in enamel of deciduous normal and carious teeth using atomic emission spectrometry. METHODS: A total of 80 deciduous molar teeth indicated for extraction from children between the age group of 713 yrs. were taken for this study. The specimens were divided into four groups and the samples were prepared using centrifuge flotation technique. They were analyzed for Manganese, Strontium and Zinc using inductively coupled plasma atomic emission spectroscopy. RESULTS: This study shows that sound enamel contains more of strontium when compared to the carious enamel. Carious enamel contains more of manganese, and zinc when compared to the normal enamel. Elements zinc and strontium occur in high concentrations, where as elements manganese occur in low concentrations in enamel. The concentrations of elements manganese, strontium and zinc does not vary in relation to sex of individual. CONCLUSION: The microelements strontium and zinc are present in high concentration. Further studies are necessary to see their potential in mineralization and anticariogenic process.
