Role of Nanoparticles in Environmental Remediation: An Insight into Heavy Metal Pollution from Dentistry

Environmental damage is without a doubt one of the most serious issues confronting society today. As dental professionals, we must recognize that some of the procedures and techniques we have been using may pose environmental risks. The usage and discharge of heavy metals from dental set-ups pollute the environment and pose a serious threat to the ecosystem. Due to the exclusive properties of nanosized particles, nanotechnology is a booming field that is being extensively studied for the remediation of pollutants. Given that the nanoparticles have a high surface area to volume ratio and significantly greater reactivity, they have been greatly considered for environmental remediation. This review aims at identifying the heavy metal sources and their environmental impact in dentistry and provides insights into the usage of nanoparticles in environmental remediation. Although the literature on various functions of inorganic nanoparticles in environmental remediation was reviewed, the research is still confined to laboratory set-ups and there is a need for more studies on the usage of nanoparticles in environmental remediation.</jats:p

General anesthesia time for the dental management of special needs patients

This journal issue entitled: 23rd iADH Congress in conjunction with the SCDA 28th Annual Meeting ... 2016Oral Presentation - Anesthesia track/sedation symposiumAIM: The aim of this retrospective audit was to determine the utilization of theatre time for dental management under GA on SNP at Queen Mary hospital (QMH). 1. To check the mean utilization of theatre time. 2. To check the correlation among theatre time and different age groups. 3. To determine the theatre time based on completion of cases. METHODOLOGY: A retrospective audit of 275 special needs dental patients treated under GA at QMH. All the patients involved were divided into three age groups based on dentitions. Data was collected in a over a 10-year (2002–11) period using a data collection sheet and analyzed using Microsoft Excel 2007. RESULTS: The retrospective audit demonstrated: the mean theatre time for dental treatment was 115±55 min. The >12 age group utilized significantly longer time 17%, 59%, 75%, and 88% cases completed on or before 60 min, 120 min, 150 min and 180 min, respectively. Recommendation and Action Plan: Further research needed for the evaluation of time for individual procedure. Cases should be planned based on need of treatment and number of cases per session should be increased. CONCLUSION: Overall 88% cases completed before scheduled time while 59% cases completed before patients with permanent dentition (>12) utilized more theatre time. This audit highlighted the importance of theatre time and to reduce patients waiting list planned DGA by increase no of cases for session

Schwartz-Jampel syndrome: a review of the literature and case report

Schwartz-Jampel syndrome (SJS) is a rare autosomal recessive skeletal dysplasia associated with myotonia. The manifestations of SJS include short stature, blepharophimosis, and skeletal anomalies. The combination of skeletal and muscular abnormalities may result in oro-dental manifestations such as atypical facies, with micrognathia, microstomia, pursed lips, crossbite, cleft palate, as well as mandibular hypoplasia, the risk of dentigerous cysts, and impacted teeth. The use of general anesthesia in patients with SJS is dangerous, as there is a risk of malignant hyperthermia. The purpose of this paper is to describe a 3-year-old Chinese boy diagnosed with SJS at birth. His intra-oral examination revealed significant dental findings such as dentin defects with generalized attrition and hypodontia of the permanent dentition. Comprehensive dental treatment was provided at the same time as lower right limb surgery to reduce the potential complications with general anesthesia. © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.link_to_subscribed_fulltex

Oral Manifestations of Noonan Syndrome: Review of the literature and a report of four cases

Noonan syndrome (NS) was described by Noonan and Ehmke as a multi-system disorder, which is typically evident at birth. The incidence of this syndrome is estimated to be one per 2500 to one per 1000 and affects both genders. While the clinical manifestations of NS have been well documented, the oral manifestations have not been extensively discussed. The purpose of the present article is to (a) review the oral manifestations of NS reported in the literature, and (b) describe four cases (three females and one male) of NS, who presented with short stature, cardiac problems and various oral findings. Based on these cases, we conclude that many oral anomalies may have possible relationships with NS, which require multidisciplinary treatment planning and timely management. The importance of oral findings in NS has largely gone unnoticed and it is essential to consider oral manifestations as scoring criteria in the diagnosis of NS.link_to_OA_fulltex

Reliability of panoramic radiographs for identifying supernumerary teeth in children

Objectives. To evaluate the reliability of panoramic radiographs (PRs) for identifying supernumerary teeth (ST) and to determine whether the level of dental training of the observer influenced the identification of ST. Methods. Seventy-five PRs were randomly selected from the patient records and 18 examiners independently rated 25 radiographs each, for specific risk factors as well as for a measure of adequacy. Subsequently, the results were paired with those of the other examiners who assessed the same set of PRs. Descriptive statistics were computed using Fisher's exact test, and kappa statistics were used to assess the inter- and intra-observer reliability. Results. Four hundred and fifty PRs were available for analysis. The overall sensitivity and specificity figures were 50% and 98.3%, whereas the positive and negative predictive values were 90.6% and 83.6%, respectively. The sensitivity figures for Junior House Dental Officers and Postgraduate Paediatric Dental Trainees were 39.2% and 60.8%, whereas the specificity figures were 99.4% and 95% with slight inter-examiner and moderate intra-examiner reliability. Conclusions. Panoramic radiographs are unreliable for identifying ST, and higher level of dental training is essential for identifying ST. © 2011 The Authors.
