Objective: To estimate and compare the levels of serum copper and iron among subjects with oral submucous fibrosis (OSMF) of different clinical stages and healthy controls. Study Design: Study sample comprised of 50 patients clinically diagnosed with OSMF and 50 healthy controls who were matched for age and gender. OSMF patients were categorised by clinical staging. Serum estimation of copper and iron was done using atomic absorbtion spectrophotometry. Results: Mean copper and iron level differed significantly (p<0.000) between the patients and controls with patients exhibiting higher copper (134.1±20.16) and lower iron (114.78±23.47) levels in contrast to controls who presented lower copper (114.8±12.36) and higher iron (130.86±31.01) levels in serum. There was a definite trend as (P<0.0001) with cases having the lesion in faucial bands (1st stage) exhibiting the lowest serum copper and those in stage 3 (faucial, labial and buccal bands) presenting the highest copper levels in serum. Conclusions: Copper level increased and iron level decreased in study group in comparison to healthy controls. Copper level increased as clinical stage of oral submucous fibrosis increased. © Medicina Oral S. L.

To evaluate the efficacy of plaque removal of four different toothbrushes in visually disabled children. Three manual toothbrushes with different bristle designs (Oral-B CrossAction 40-regular, Oral-B ShinyClean 40-soft, Oral-B Advantage 40-soft) were compared with an electric toothbrush with an oscillating rotating head (Colgate Motion). Forty visually impaired children in a professional education center participated in the study and were divided into 4 groups of 10 participants each. To obtain a plaque-free condition at baseline, professional toothcleaning was performed on each participant. After instructions on how to use the toothbrushes, each group started the experiment using a differently designed toothbrush. After 1 week of application, the Quigley Hein plaque index (QHI) was used to assess the oral hygiene status of each participant. Student's t-test was chosen for comparing brushes. P < 0.01 was considered as the significance level. Results were presented as mean ± standard deviation. The QHI values obtained with the electric Colgate Motion brush were the lowest (0.088 ± 0.051) and Advantage (0.801 ± 0.132) the highest. Although the QHI values with the manual Oral-B CrossAction (0.439 ± 0.094) were lower than those with the Oral-B shiny clean (0.503 ± 0.098), there was no statistical difference between the two. The electric toothbrushes are still the most effective in the visually disabled group. However, because of cheaper cost, easier availability and use, the Oral-B CrossAction toothbrush with criss-cross bristles could be a suitable alternative.

To record, determine and discuss the gender influence on the overall prevalence of occlusal characteristics of primary dentition of 4- to 6-year-old children of Bagalkot City, India. A total of 1000 children (583 boys and 417 girls) 4 to 6 years old were evaluated clinically for primary molars, primary canines, developmental spaces, measurements of overjet and overbite, crowding, anterior or posterior cross bite, midline discrepancies, lateral profile, as well as assessment of the presence of lip incompetency. A stratified cluster random sampling procedure was executed to collect the representative sample. Highly significant differences between males and females were observed for the prevalence of flush terminal plane molar relationship, class I and II canine relationship, overjet and overbite of 0 to 2 mm, and for both convex and straight profile. A significant difference was seen for the occurrence of mesial step and asymmetric molar relationship, presence of developmental and primate spaces, shift in maxillary dental midline, presence of both single tooth anterior and bilateral posterior cross bite, overjet of 2 to 4 mm and convex profile. The data revealed that most of the children had a malocclusion and that there was a significant difference between male and female occlusal characteristics. This highlights the importance of identifying children who are in need of orthodontic treatment for dental health or aesthetic reasons. The study also indicated that the prevalence of most of the occlusal characteristics were comparable with other communities, but there existed substantial differences in prevalence of some traits.

Dental chair units (DCUs) are used in the treatment of many patients throughout each day and microbial contamination of specific component parts is an important potential source of cross-infection. The quality of dental unit water is of considerable importance since patients and dental staff are regularly exposed to water and aerosols generated from the dental unit. This water hosts a diverse microflora of bacteria, yeasts, fungi, viruses, protozoa, unicellular algae and nematodes which may be contaminated with micro-organisms found in the biofilm formed due to water stagnation in the narrow-bore dental unit waterline (DUWL) tubings. The water thus contaminated, when used for various treatment procedures through dental handpieces, air/water/three-in-one syringe, etc., produces aerosols that can cause infection. The present review emphasises the risks of infection from DUWL and various water treatment procedures available to disinfect the DUWLs. © 2009 The Hospital Infection Society.

OBJECTIVE: To compare the caries status and oral hygiene behaviour of dental and medical students and to assess the influence of oral hygiene behaviour on the caries status. METHODS: A questionnaire survey was conducted to assess the knowledge, attitudes and behaviour along with clinical examination to asses the caries status. A total of 403 dental and medical students enrolled with Rajasthan University of Health Sciences of Udaipur district, India were recruited in the study. RESULTS: 56.4% of dental students brushed their teeth twice daily compared to 38.5% of medical students. There was no significant difference between the mean decayed components of males and females of dental stream, whereas among medical subjects, males had a higher decayed score than females (P = 0.012). The mean behaviour score obtained by dental students (19.38) was greater than that of medical students (18.34). Moreover, medical students presented a higher decayed, missing and filled teeth (DMFT) score (1.96) than dental students (1.16). Subjects who had a habit of brushing after every meal showed lower DMFT score (1.4) than those who brushed only once a day (1.64). Step-wise linear regression analysis revealed that course of education and final behaviour score were the best predictors for the DMFT status. CONCLUSION: This study revealed significant differences between the oral hygiene behaviour and caries status of dental and medical students; furthermore, caries status was significantly influenced by the oral hygiene behaviour.

Dandy-Walker malformation (DWM) is a rare intracranial congenital abnormality that affects the cerebellum and some of its components; particularly cerebellar vermis, fourth ventricle and is characterized by an enlarged posterior fossa. Although there is an extensive list of signs attributed to DWM, final diagnosis is solely dependent on imaging techniques as there are no signs that are characteristic of DWM. This article reports a case with DWM who was diagnosed by magnetic resonance imaging.

Aim. To compare the pain perception using a traditional Syringe vs Computer controlled 'Anaeject' device in supra periosteal injections. Methodology. One hundred volunteers were selected on a random basis for the study and were explained about the goals of study and signed the consent form. They served as their own controls, i.e. in the same subject both the computer controlled 'Anaeject' device and traditional syringe were used on the contralateral sides for obtaining anesthesia. Pain levels were recorded during needle prick and anesthetic delivery. Post-operative pain at the site of injection 5 h after the anesthesia was also recorded. Heft Parker visual analog scale (VAS) was used to evaluate pain levels. Results. Final analysis was done on 90 subjects. Subjects reported significantly lower pain ratings at the time of needle prick and the delivery of local anesthetic using a computer-controlled 'Anaeject' device as compared to traditional syringes. Pain at the site of injection 5 h post-operative was also low in the computerized anesthesia group but it was not statistically significant. Conclusion. In this in vivo study it was found that subjects perception of pain was significantly low for supraperiosteal injections while using computerized anesthesia as compared to that of conventional disposable syringes. © 2013 Informa Healthcare.

Objective To assess the erosive potential of 94 pediatric medicines of various therapeutic groups in vitro. Methods In vitro measurement of endogenous pH and titratable acidity (mmol) of 94 formulations was done. Endogenous pH was measured using a pH meter, followed by titration with 0.1-M NaOH using phenolphthalein as indicator. Results Overall, 55 (59%) formulations had an endogenous pH of <5.5. The mean (±SD) endogenous pH and titratable acidity for 45 SC formulations were 5.52±1.18 and 0.165± 0.131 mmol, respectively; for 49 sugars-free (SF) formulations, these figures were 5.81±1.43 and 0.393±1.225 mmol (P>0.05).Compared with their SC bioequivalents, eight SF medicines showed no significant differences for pH or titratable acidity, while 10 higher-strength medicines showed lower pH (P 0.035) and greater titratable acidity (P 0.026) than their lower-strength equivalents. Chewable and dispersible tablets, gastrointestinal medicines and antibiotics were significant predictors of higher pH. In contrast, effervescent tablets, and nutrition and blood preparations were significant predictors of higher titratable acidity. Conclusions Pediatric SF medicines were not more erosive than SC medicines in vitro; a more significant predictor of their erosive potential was dose form. Higher the dose form more was the erosive potential of the medicine.

OBJECTIVE: To evaluate the effect of oral hygiene behaviour, dental anxiety, self assessed dental status and treatment necessity on dental caries status of medical students. METHODS: The study was conducted among 345 medical students of Udaipur city, India who had provision for free dental services and the study was based on a questionnaire which consisted of two parts, first part containing questions regarding self assessment of dental status and treatment necessity along with oral hygiene behaviour and the later part comprised of Corah Dental Anxiety scale (DAS). Clinical examination was based on the WHO caries diagnostic criteria. RESULTS: Females perceived greater dental anxiety than males. Individuals claiming poor dental status had higher mean decayed, missing and filled teeth (DMFT) score (6.67) than good (2.89) and fair (4.44). The mean decayed component among the anxious students (5.4) was almost twice that of less anxious (2.77) student population. DAS constituted the first major contributor for missing component followed by smoking status which alone explained a variance of 7.1%. The cumulative variance explained by all the independent variables on the DMFT status accounted to 56.4% with self assessed dental status alone contributing a variance of 44.9%. The most significant (P < 0.001) contributor for filled component was self assessed dental status (14.5%). CONCLUSIONS: Oral hygiene behaviour, dental anxiety, self assessed dental status and treatment necessity significantly affected the dental caries status of medical students.

PURPOSE: The objective of the present study was to determine if there existed any difference between the attitudes and behaviour apart from dental caries status among health professional and other professional college students and to investigate the association of oral health attitudes and behaviour with dental caries. MATERIALS AND METHODS: The Hiroshima University-Dental Behaviour Inventory (HU-DBI) questionnaire was used to survey 1824 young student population of Udaipur, India. Dental caries status was evaluated using the World Health Organization caries diagnostic criteria for decayed, missing and filled teeth and surfaces (DMFT and DMFS, respectively). RESULTS: There was a significant difference (P < 0.05) between the health professional and other professional college students for various components of DMFT and DMFS. Moreover, health professional students reported significantly higher HU-DBI scores (better oral health attitudes and behaviour) than their comparative group. Untreated dental caries played a major contribution to the total DMFT scores in both the groups, with 0.23 and 0.28 mean decayed teeth reported among health professional and other professional students, respectively. Decayed and missing teeth components exhibited a significant negative correlation with HU-DBI scores, whereas a positive correlation existed with the filled teeth component. CONCLUSIONS: A difference existed between the health professional and other professional students with regard to caries experience, oral health attitudes and behaviour. DMF indices and their components were related to most of the oral health attitudes and behaviours. Decayed and missing teeth components were negatively related while filled component was positively related to HU-DBI score.
