RESUMEN

Background/aim: Dental trauma draws attention in special children due to its risks and consequences. The aim of this study was to estimate the prevalence, etiology, and risk factors of traumatic dental injuries in children with special healthcare needs of Puducherry. Materials and methods: A cross-sectional survey among 121 special children aged 4-18 years was carried out in Puducherry. The children were examined for the presence of traumatic dental injuries (TDI) and associated risk factors for the occurrence of trauma and classified according to the WHO epidemiological field survey classification. Results: Prevalence of TDI was 40.5%. The majority of them were restricted to enamel fractures and the most commonly affected were permanent maxillary central incisors. The most common cause of injury was ˝falling over˝ and home was the frequent place of injury to occur. The risk factors associated with TDI were mesoprosopic facial form, convex facial profile, increased overjet, Angles Class II molar relationship, posterior facial divergence, and incompetent lips which were statistically significant. Conclusion: The study concludes the prevalence of TDI is more prevalent in CSHCN, thereby it is necessary to create awareness, health education, and periodic screening for efficient treatment.

RESUMEN

Early childhood caries is indeed a devastative situation for both patients' parents and pediatric dentists. The primary goal in treating severe early childhood caries is to restore normal function such as maintenance of mesiodistal and vertical dimension, prevention of alteration of mastication, phonetics (due to premature loss), development of parafunctional habits, and prevention of psychological problems affecting the self-esteem of a child. The restoration of primary dentition with extensive carious lesions is a complex clinical challenge of several dimensions. The severity of this condition in maxillary anterior teeth has prompted the extraction of teeth due to inadequate esthetic treatment options. The only concern with the severely destructed primary incisors is a lack of crown structure, which fails to support and adhere to a composite crown. Clinicians have preferred many restorative modalities for esthetic rehabilitation of badly decayed anterior primary teeth with numerous root canal retentive post and core systems with appropriate techniques to preserve those teeth until they are replaced by permanent teeth. This review highlights the various posts, their indications, principles, ideal properties, and the current concepts on their use in pediatric dentistry.

RESUMEN

National recommendations encourage the development of ambulatory surgery. This form of treatment, reserved mainly for short procedures, can also be used for more complex operations such as a total knee replacement. The teams at Vitré general hospital share their experience and emphasise the need to ensure the compliance of patients and their family.

RESUMEN

Polyethylene terephtalate (PET) and Polypropylene (PP) textiles are widely used in biomedical application such as wound dressings and implants. The aim of this work was to develop an antibacterial chitosan (CHT) coating activated by silver or by iodine. Chitosan was immobilized onto PET and PP supports using citric acid (CTR) as a crosslinking agent through a pad-dry-cure textile finishing process. Interestingly, depending on the CHT/CTR molar ratio, two different systems were obtained: rich in cationic ammonium groups when the CTR concentration was 1%w/v, and rich in anionic carboxylate groups when the CTR concentration was 10%w/v. As a consequence, such samples could be selectively loaded with iodine and silver nitrate, respectively.Both types of coatings were analyzed using SEM and FTIR, their sorption capacities were evaluated toward iodide/iodate anions (I(-)/IO3(-)) and the silver cations (Ag(+)) were evaluated using elemental analysis. Finally, in vitro evaluations were carried out to evaluate the cytocompatibility on the epithelial cell line. The silver loaded textile reported a stronger antibacterial effect against E.coli (5 log10 reduction) than toward S. aureus (3 log10) while the antibacterial effect of the iodide loaded textiles was limited to 1 log10 to 2 log10 on both strains.

RESUMEN

BACKGROUND: According to the World Health Organization guidelines, field tests, in the context of a bid for the supply of alcohol-based hand rubs, should take into account climatic region, test period, products already in use, and type of use (hygienic or surgical) when assessing tolerance. This laborious method is often contested. OBJECTIVE: To conduct a post hoc analysis of the data of a large bid, including 5 factors, to validate the relevance of their inclusion. METHODS: For the purposes of the bid, products were compared in terms of the 4 World Health Organization tolerance criteria (appearance, intactness, moisture content, sensation) during product testing and were separated into groups on the basis of the studied factors. The post hoc analysis method included (1) comparison of the mean before-and-after difference based on the self-evaluation of the skin with the 4 World Health Organization tolerance criteria, between climatic regions, periods, products in use, test product, and the type of use; (2) generalized linear models, taking into account all studied factors. RESULTS: The analysis included data for 1,925 pairs of professionals. The means of the differences observed were independently and significantly associated with the test period (P<.001), the hygienic or surgical use (P=.010 to .041, not significant for appearance), the product already in use (significant for appearance P=.021), and the test product (P<.001). The association with climatic region was found to be significant only in the nonadjusted analysis. CONCLUSION: The type of use, the test period, and the product in use should be taken into account when designing field tests of alcohol-based hand rubs.

RESUMEN

The aim of this work was to develop an antibacterial multilayer coating activated with methylene blue (MB) and based on chitosan (CHT) and cyclodextrin polyelectrolyte (polyCD) onto a non-woven polyethylene terephthalate (PET) textile support. The MB-free and MB-loaded systems were built-up by applying the dip-coating technique, alternating soak cycles of the PET textile preliminarily modified with carboxylate groups in CHT and in polyCD or polyCD/MB complex solutions. The layer-by-layer assembly build-up was followed by optical waveguide lightmode spectroscopy on the one hand and by gravimetry once it was applied on the textile substrate on the other hand. Two chitosan grades were used, low molecular weight (CHT-L) and medium molecular weight (CHT-M). The influence of the molar ratio CD/MB in the polyCD solutions was varied and finally the system underwent a post reticulation with genipin. Such parameters influences were investigated with regard to the loading capacity in MB of the systems, the release kinetics profiles of MB in pure water, phosphate buffer and MEM media, and the degradation of the self-assembled coating in the same media. Finally, biological and microbiological tests were performed to demonstrate the cytocompatibility of the systems and their ability to display a sustained antibacterial effect of the device through the MB prolonged release.

RESUMEN

The aim of this work was to develop the formation of multilayered coating incorporating a cyclodextrin polyelectrolyte onto a non-woven polyethylene terephthalate (PET) textile support in order to obtain reservoir and sustained release properties towards bioactive molecules. We optimized the multilayer assembly immobilization onto the PET surface according to the layer-by-layer (LbL) deposition process. After a pre-treatment of the textile support aiming to offer a sufficient ionic character to the surface, it was alternatively immersed into two polyelectrolytes aqueous solutions consisting of chitosan (CHT) as polycation on the one hand, and a ß-cyclodextrin polymer (polyCTR-ßCD) as polyanion on the other hand. In a second approach, a TBBA/polyCTR-ßCD complex (4-tert-butylbenzoic acid, TBBA) was used in order to load the system with a drug model whose kinetics of release was assessed. Gravimetry, microscopy, OWLS, colorimetric titration, infrared and zetametry were used as characterization techniques. An effective deposition on the textile surface due to ionic interactions with alternation of up to 10 layers of each of both polyelectrolytes was clearly evidenced. However, we observed that layer formation occurred to a lesser extent when TBBA/polyCTR-ßCD complex was applied instead of polyCTR-ßCD alone. The release study showed that drug reservoir properties and release kinetics could be controlled by the number of layers in the system and that TBBA release was faster than the multilayered coating degradation.
