The sample comprised 56 children, 28 with MIH and 28 without MIH (comparison group), and their gardens (n=56). For the perception data we used the Child and Parent’s Questionnaire of Teeth Appearance. We used the European Academic of Paediatric Dentistry (EAPD) criteria to define MIH. Caries experience was assessed by Decayed, Missing and Filled Teeth (DMFT) index. Chi-square, Student’s t-test and correlation tests were used with significance level set at 5%. Most children were male (n=35; 62.5%) and patients with MIH perceived their affected teeth as stainned (p=0.01). MIH was considered by parents (6.96±1.7) to enhance psychosocial condition (social, physical, and psychological social) of their children (p<0.01). Patients with severe MIH showed the worst perception about the color of the teeth (p=0.07). There was no correlation between DMFT scores and presence of MIH (p=0.80). Patients and parents perceived MIH. Groups with severe MIH (children/ parents) showed the worse aesthetic perception.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41964319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample was composed of students and employees from the Dental School of the Federal University of Rio de Janeiro (n = 20, 10 men and 10 women with mean age of 47.60 ± 15.70 and 20.50 ± 2.1, respectively). The collections were performed with an interval of at least one day between them and the participants were instructed to stay for less than 30 minutes without eating food and brushing teeth. Samples were stored at -20°C until DNA extraction was performed using a commercially available kit (Qiagen®). Differences in DNA yield between methods were test for statistical significance with an alpha of 0.05. No sexual dimorphism was observed in relation to the concentration of DNA (p=0.76), age (p=0.91), and ethnicities (p=0.72). There was no significant difference between the collection methods in relation to the quantity and purity of the extracted DNA (p≥0.05).

O’Donnell, M. Oakley","doi":"10.5195/D3000.2019.85","DOIUrl":"https://doi.org/10.5195/D3000.2019.85","url":null,"abstract":"Opioid analgesics, when taken as prescribed, are effective therapeutic options that provide pain relief for moderate to severe pain. The use of opioids in the treatment of pain has been increasing in the U.S. at an alarming rate, possibly contributing to the simultaneous rise in opioid abuse. Emergency departments play a major role in managing patients who present in pain, with approximately 10% of all opioid analgesic prescriptions written in hospital emergency departments. It is estimated that dental pain patients represent between 0.3-4% of the overall patient emergency department workload. Yet, the literature suggests that many of these physicians may not have sufficient training in handling dentofacial emergencies. The goal of this study was to systematically review the available literature on the topics of: 1) emergency department physicians’ training related to treating dental pain patients, and 2) the frequency in which they prescribe opioid medications to these patients. Methods: A systematic literature review was conducted among publications from 1985-2014 in the databases PubMed, Ovid, and Science Citation Index. The following search terms were used in this systematic literature review in order to identify the available literature of interest: “opioid and dental and emergency departments,” “dental pain and drug abuse,” “ER physicians and dental pain,” “ER physicians and drug abuse,” and “dental pain and emergency departments.” Publications in any language or country were considered, as well as editorials and commentaries. Findings: A total of 769 publications were identified. Seventeen publications met the criteria for inclusion. Eight studies commented on the emergency department physicians’ perceived “lack of training” in handling dentofacial emergencies and found that the majority of this group did not feel comfortable in managing dental patients. Nine studies assessed the frequency in which physicians prescribe pain medications to dental patients. Within these 9 studies, 5 specifically reported that between 29.6% and 81% of dental patients treated, received an “opioid” or a “narcotic” upon discharge. The remaining 4 studies in this group instead used non-specific terms that included “prescription medications,” “analgesics,” “pain medicine,” and “pharmacotherapy” to describe their findings and did not particularly report opioid prescribing trends. Of those publications rejected, 9 addressed the topic of dental pain patients presenting to non-dental providers, but did not include data that met the criteria related to emergency department prescribing frequency or physician training. Conclusions: This review of the literature suggests that emergency department physicians’ training level in treating dentofacial pain is less than ideal. It also confirms that individuals presenting to emergency departments with dental pain are a subset of the population of patients who are prescribed opioids as an analgesic.

I have witnessed dentures that had not been removed or cleaned in years. I have seen tube-fed residents who had not had their teeth brushed in months because of the staff ’s failure to see the necessity of providing oral homecare. I recently treated a patient who had so much tartar build up on his lower anterior teeth that he could not close his mouth or properly chew his food. I have listened to the countless, heart-wrenching accounts of elders so embarrassed by their dental condition that they were ashamed to smile or even let me examine their mouths. Dental health plays a significant role in mental and emotional health and well-being. Therefore, caregiver provision of proper oral homecare helps maintain the dignity of the geriatric community. Whether the neglect is due to caregivers’ lack of knowledge or lack of compassion, the result is detrimental to the systemic health of the elderly. Uncontrolled oral bacteria can lead to pneumonia, diabetes, strokes, and heart attacks. It has even been linked to Alzheimer’s Disease. Frequently, cognitive impairment intensifies preexisting oral problems. For instance, elders with Alzheimer’s typically have poor oral care and a higher incidence of oral diseases. The most deplorable aspect of this situation is the fact that it is readily preventable. The quality of life and systemic health of residents in long term care facilities can be significantly improved by simple, consistent, and effective oral care practices. 31 Open Journal of Geriatrics V1 . I1 . 2018 Solh 2011) Death rates vary from 1 to 48% and are associated with age, comorbidities, and the severity of the disease (Welte et al. 2012). Clinically, residents feel sick and present with cough, purulent sputum, fever, sweats, pain, and suffocation hazard. Very old residents lack these classic symptoms and rather present with disorientation and some may even fall (Janssens and Krause 2004). Silent aspiration of treacherous oral microorganisms resulting from poor oral hygiene is a major contributing factor to nursing home pneumonia. It can be found in places we would never suspect. There is evidence for the first time that denture wearing during sleep doubles the risk of pneumonia in very old people (Iinuma et al. 2014). Microorganisms of denture plaque associated with periodontal disease were found in the lungs of patients who were denture wearers. (Imsand et al. 2002). The tongue is another place that harmful oral microorganisms populate. A study was conducted on seventy-one edentulous residents of long term care facilities age 65 years and older. The study evaluated the quantity of tongue-coating and found that elderly residents whose tongues were coated had “significantly higher salivary bacterial counts” than those whose tongues were not coated. The study also revealed that the risk of developing pneumonia was hi","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70619802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Myofibroblasts are known to play a pivotal role in normal growth and development, wound healing, organ fibrosis and cancers. The role of myofibroblasts in the remodeling of ECM in various intraosseous lesions may affect the nature and growth of these lesions by influencing matrix formation, cellular proliferation, cellular migration, angiogenesis, and extracellular proteolytic activity. Aim and Objective: The following study was undertaken to evaluate the expression of α- smooth muscle actin in intraosseous lesions of the jaw and to correlate their role with the pathogenesis or progression of these diseases if any. Material and Methods: A total of 75 cases of Intraosseous lesions of the jaw formed the study sample. The study sample was further categorized into six groups as- Inflammatory lesions, Reactive Lesions, Benign Neoplasms, Malignant Neoplasms, Odontogenic Cysts, and Fibro-osseous Lesions. The sections were stained using Standard Hematoxylin and Eosin staining and Immunohistochemical staining for α-Smooth Muscle Actin (α- SMA). The sections were scanned at low magnification to identify positively stained areas (Hot Spots). Maximum of 10 hotspots (positive fields) were selected for quantitative scores. Statistical Analysis: Data was examined for statistical significance (p-value) using One-way analysis of variance (ANOVA) for four groups and Post Hoc tests for multiple comparisons (Tukey HSD). Results: Group II (Reactive lesions) shows highest immunoexpression (2.56) followed by Group IV (Malignant neoplasms-1.83), Group III (Benign neoplasms-1.67), Group VI (Fibro-osseous lesions-1.57), Group V (Odontogenic jaw cysts-1.50) and Group I (Inflammatory lesions-0.40).
