BackgroundTraumatic dental injuries to anterior teeth are a significant public health problem, not only because their prevalence is relatively high, but also because they have considerable impact on children’s daily lives. Traumatic dental injuries (TDIs) cause physical and psychological discomfort, pain and other negative impacts, such as tendency to avoid laughing or smiling, which can affect social relationships.ObjectivesThis study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12-year-old school children in Kashmir, India.Patients and MethodsA cross-sectional study was conducted in private and government schools of India among 1600 schoolchildren aged 12 years. In addition to recording of the type of trauma (using Ellis and Davey classification of fractures, 1970), over jet, Angle’s molar relation and lip competence were also recorded. The socioeconomic status and academic performance of the study subjects were registered. The data obtained were compiled systematically and then statistically analyzed. The statistical significance for the association between the traumatic injury and the variables was analyzed using the chi-square test. Logistic regression was used to identify potential risk predictors of TDIs.ResultsThe overall prevalence of TDI to anterior teeth was found to be 9.3%. The TDI to anterior teeth in male was more than female, but the difference was statistically nonsignificant (P < 0.01). Falls and sports were the most common causes of trauma in the present study. The highest potential risk factor for the occurrence of trauma was over jet. Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model.ConclusionsIt was concluded that the prevalence of traumatic dental injuries was 9.3%. Traumatic dental injuries among children exhibit complex interaction between the victims’ oral conditions and their behavior. Therefore, prevention should consider a number of characteristics such as oral predisposing factors, environmental determinants and human behavior. It is recommended that specific and proper public places for leisure and sports activities, with impact-absorbing surfaces around the items on which children are most likely to fall, should be provided.
Objective: To evaluate the addition of titanium dioxide (TiO2) nanoparticles and cetylpyridinium chloride (CPC) on the compressive strength and antibacterial activity of conventional glass-ionomer cement (GIC). Study design: TiO2 nanoparticles enriched GIC was prepared by adding 3% TiO2 nanoparticles (w/w) into the powder component of conventional GIC. CPC containing GIC was developed by incorporating 1% CPC (w/w) into conventional GIC powder. Samples were segregated into three groups: GIC with 3% TiO2 nanoparticles, GIC with 1% CPC and unmodified conventional GIC. Compressive strength was assessed using the universal testing machine on cylindrical specimens made from each material. Antibacterial activity was assessed by measuring inhibition zones on Mitis Salivarius Bacitracin (MSB) agar inoculated with pure strain of Streptococcus mutans (S. mutans). Results: GIC containing TiO2 nanoparticles exhibited significantly greater compressive strength as compared with CPC and conventional GIC groups (P < 0.01). However, there was no significant difference between the compressive strengths of CPC and conventional GIC group (P >0.05). Antibacterial activity was significantly greater for TiO2 group than conventional GIC (P <0.05). CPC increased the antibacterial activity of conventional GIC, though not significantly. Conclusion: The addition of 3% TiO2 nanoparticles improves the compressive strength of GIC as well as its antibacterial activity against S. mutans.
IntroductionThere are above 170 PICUs identified in the UK. A modest body of research has emerged documenting characteristics of PICU populations. Comprehensive data describing patients admitted to PICUs remains incomplete. There is no data on Female only PICU population's characteristics.ObjectiveTo offer the first and the only project data country wide up to date on Female only PICU population. It describes socio-demographic characteristics, mental state and outcome of treatment for 49 patients admitted to the first Female PICU in NHS in UK in 2008MethodProspective case note analysisResults65% of patients were single, 73% were Caucasian and 26% had BME background. Most of patients were admitted from police stations and detained under S2 or S3 of the MHA. Most dominant diagnoses were Schizophrenia and Personality Disorder. 77% of admissions were due to physical aggression and severe self harm. Most patients had more than 5 previous admissions to Mental Health wards. Half of the patients received intramuscular Rapid Tranquilization during the admission and 22% were placed in Enhanced Care Area. Median length of stay did not exceed recommended 8 weeks but some patients with the diagnosis of Personality Disorder experienced an excessive length of PICU stay. Most patients were transferred to open acute wards.ConclusionsPatients admitted to Female PICU were most likely to have major psychosis or personality disorder, admitted due to violence or self harming behavior, more likely to exceed recommended max length of stay if diagnosis of PD was given, BME group being represented.
