The population of older people, as well as the number of dependent older people, is steadily increasing; those unable to live independently at home are being cared for in a range of settings. Practical training for nurses and auxiliary care staff has frequently been recommended as a way of improving oral health care for functionally dependent elderly. The aim was improve oral hygiene in institutionalized elderly in Bangalore city by educating their caregivers.The study is a cluster randomized intervention trial with an elderly home as unit of randomization in which 7 out of 65 elderly homes were selected. Oral health knowledge of caregivers was assessed using a pre-tested pro forma and later oral-health education was provided to the caregivers of the study group. Oral hygiene status of elderly residents was assessed by levels of debris, plaque of dentate and denture plaque, and denture stomatitis of denture wearing residents, respectively. Oral-health education to the caregivers of control group was given at the end of six months.There was significant improvement in oral-health knowledge of caregivers from the baseline and also a significant reduction of plaque score from baseline score of 3.17 0.40 to 1.57 0.35 post-intervention (p < .001), debris score 2.87 0.22 to 1.49 0.34 (p < .001), denture plaque score 3.15 0.47 to 1.21 0.27 (p < .001), and denture stomatitis score 1.43 0.68 to 0.29 0.53 (p < .001).The result of the present study showed that there was a significant improvement in the oral-health knowledge among the caregivers and oral-hygiene status of the elderly residents.

The presence of micronuclei (MN) in mammalian cells is related to several mutagenetic stresses. MN are formed as a result of chromosome damage and can be readily identified in exfoliated epithelial cells. MN is chromatin particles derived from acentric chromosomal fragments, which are not incorporated into the daughter nucleus after mitosis. It can be visualized by chromatin stains. A variety of factors influences the formation of MN in cells such as age, sex, genetic constitution, physical and chemical agents, adverse habits such as tobacco, areca nut chewing, smoking, and alcohol consumption. Micronucleation has important implications in the genomic plasticity of tumor cells. The present paper reviews the origin, fate and scoring criteria of MN that serves as a biomarker of exposure to genetic toxins, and for the risk of cancer.

The study was aimed to evaluate the microleakage of Biodentine using two different manipulation methods by dye penetration.A total of 60 single-rooted human maxillary permanent teeth were cleaned and obturated with gutta-percha using lateral condensation method. Standardized root-end cavities were prepared after apical resection. All teeth were divided randomly into two groups of 30 specimens and were filled with Biodentine by trituration and hand manipulation methods. The samples were coated with varnish and immersed in 1% methylene blue dye for 72 h. Then the teeth were sectioned longitudinally and observed under a stereomicroscope. The depth of dye penetration was measured in millimeters.There was highly statistical significant difference observed between Group I and Group II (P < 0.001) when dye penetration scores were compared.More microleakage was seen when Biodentine was manually manipulated as compared to machine trituration.

Although a number of studies have been undertaken to evaluate the friction characteristics of self-ligating brackets, there have been only few studies which have actually evaluated the clinical efficiency of these self-ligating brackets. This study was done to evaluate the clinical efficiency of Passive SLB (Smart Clip) in terms of anchorage loss and total treatment duration by comparing it with a Conventional pre-adjusted edgewise (M.B.T.) bracket system.This was a retrospective study in which the study sample comprised of ten patients treated with Passive SLB (Smart Clip, 0.022) and ten patients treated with Conventional pre-adjusted edgewise (M.B.T.) bracket system (0.022) who required therapeutic extraction of U/L first premolars as a part of their orthodontic treatment plan. Pretreatment and post treatment lateral cephalograms were taken to evaluate the amount of anchorage loss. The total time required to complete the treatment was also recorded.Anchorage loss observed with Passive SLB (Smart Clip) sagittally was 1.900.68mm in the maxilla and 1.900.43mm in the mandible and vertically was 0.520.53mm in the maxilla and 0.700.69mm in the mandible. Anchorage loss observed with Conventional pre-adjusted edgewise (M.B.T.) bracket system sagittally was 2.080.43mm in the maxilla and 1.950.44mm in the mandible and vertically was 0.500.49mm in the maxilla and 0.680.53mm in the mandible. The average time taken for the completion of treatment in Passive SLB (Smart Clip) and Conventional pre-adjusted edgewise (M.B.T.) bracket system was 14.02.4 and 17.22.6 months respectively.There was no statistically significant difference in the quantum of anchor loss between Smart Clip self-ligating bracket system and Conventional pre-adjusted edgewise (M.B.T.) bracket system although Smart Clip self-ligating bracket system is efficient in reducing the overall treatment time.

The purpose of this study was to evaluate and compare the apical extrusion of debris and irrigant using various rotary instruments with crown down technique in the instrumentation of root canals.Thirty freshly extracted human permanent straight rooted mandibular premolars with minimum root curvature of 0-10 were divided in three groups with 10 teeth in each group. Each group was instrumented using one of the three rotary instrumentation systems: Rotary Hero shapers, Rotary ProTaper and Rotary Mtwo. One ml of sterile water was used as an irrigant after using each instrument. Debris extruded was collected in pre weighed glass vials and the extruded irrigant was measured quantitatively by Myers and Montgomery method and was later evaporated. The weight of the dry extruded debris was calculated by comparing the pre and post instrumentation weight of glass vials for each group.Statistical analysis was done by using by a Kruskal-Wallis One-way ANOVA test.Statistical analysis showed that all the rotary instruments used in this study caused apical extrusion of debris and irrigant. A Statistically significant difference was observed with Rotary ProTaper and Rotary Mtwo groups when compared with Rotary Hero shapers. But no significant difference was observed between Rotary ProTaper and Rotary Mtwo groups.After instrumentation with different rotary instruments, Hero shapers showed a less apical extrusion of debris and irrigant.

Traumatic injuries to the dento-alveolar structures are emergencies that compromise the quality of life of the patients. In addition to symptomatic management, definitive functional restoration and suitable rehabilitation becomes a major treatment objective in such cases. The dynamics of the traumatic forces may cause multiple injuries of different grades to the oral and para-oral structures, which makes comprehensive management a greater challenge to the dentist. The present case report elaborates a modified esthetic splint designed to treat multiple dental injuries in children, which can promote healing, restore optimal functionality along with esthetic rehabilitation to psychologically benefit the child during the time of recovery.

Ameloblastoma is an uncommon epithelial odontogenic neoplasm that is nonmineralized, locally aggressive, and, in most cases, benign. Most ameloblastomas develop in the molar-ramus region of the mandible with 70% of them arising in the molar-ramus area. Radiologically they are unilocular or multilocular radiolucency with a honeycomb or soap bubble appearance. The radiographic appearance of ameloblastoma can vary according to the type of tumor. CT is usually helpful in determining the contours of the lesion, its contents, and its extension into soft and hard tissues. Through this case we would bring to light some of the unusual CT findings which include the destruction of the surrounding structures by the lesion which appeared to be normal routine lesion when viewed clinically.
