Vongsawan, Wananong Watcharakirin, Pim Khererat","doi":"10.26502/droh.008","DOIUrl":"https://doi.org/10.26502/droh.008","url":null,"abstract":"Introduction: Root canal infection is a common consequence of dental caries which can cause premature loss in primary dentition. The exposure of pulp tissue to the oral environment allow oral microorganisms to access into the pulp chamber and lead to pulp necrosis without treatment. To identify bacteria associated with root canal infection would be beneficial and lead to providing more effective treatment. Aims: To quantify Lactobacilli and Enterococcus faecalis levels in infectious root canal of primary teeth between irreversible pulpitis and pulp necrosis groups, and to analyze the association between these bacteria and clinical signs and symptoms. Materials and methods: Total subjects were 170 Thai children aged 2-10 years old. All subjects were selected from patients who came to the pediatric dental clinic, Pediatric Department, Faculty of Dentistry, Mahidol University, Thailand and needed a pulpectomy treatment. DNA extraction and quantitative real-time PCR was performed. Results: Mean age of the children was 5 ± 1.3 years old. One hundred and ten samples were diagnosed with irreversible pulpitis and 60 with pulp necrosis. One hundred and seven subjects (63%) had a history of pain. One hundred and twenty subjects (71%) had clinical signs and symptoms. One hundred and thirty-four radiographs (79%) showed radiographic pathology. The detection of total bacteria, Lactobacillus and E. faecalis was 100%, 100% and 84% (142/170), respectively. The ratio of Lactobacillus and E. faecalis to total bacteria levels was 20% and 9%, respectively. When compared between irreversible pulpitis and pulp necrosis groups, the quantities of total bacteria (p=0.000), Lactobacillus (p=0.000) and E. faecalis (p=0.001) in pulp necrosis group were higher than those of the irreversible pulpitis group. The ratio of Lactobacillus to total bacteria in the pulp necrosis group was higher than in the irreversible pulpitis group (p=0.004), whereas the ratio of E. faecalis to total bacteria was not different between the two groups. Only Lactobacillus was associated with a history of pain (p=0.013). Gingival swelling was correlated with Lactobacillus quantities (p=0.01). When analyzed within each group, E. faecalis quantity was correlated with clinical pain (p=0.01) in pulp necrosis group. In the irreversible pulpitis group, the data showed pathologic finding of lamina dura (p=0.000) and furcation involvement (p=0.016) which correlated with E. faecalis quantities. Conclusion: The bacterial levels of total bacteria, Lactobacillus and E. faecalis in pulp necrosis group were higher than the irreversible pulpitis group. Levels of Lactobacillus and E. faecalis were associated with a history of pain, pathologic finding of lamina dura and furcation involvement. Gingival swelling was correlated with Lactobacillus quantities.","PeriodicalId":93742,"journal":{"name":"Dental research and oral health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69345400","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}

A total numerical expression of the hygienic state is calculated and the digital index is called an oral hygiene index. The aim of the study is to describe the relationship between OHI-S and PBI-S in childhood. Material and Methods: Object of observation. The study is about the oral hygiene status of 60 children aged 6 years. Oral-Hygiene Index, OHI-S Greene and Vermillion (PI / 6 + CI / 6) - (Modified) is used to establish Oral Hygiene status. The research also includes the condition of the gingiva by evaluating the Papilla Bleeding Index (PBI-S) - Ainamo and Bay. Location of the study: University Medical Dental Center Varna, Faculty of Dental Medicine. After processing the results and determination of the highlights was conducted by actual survey data processing package for mathematical and statistical analysis SPSS v 20.0. Results: Comparison of OHI-S results according to PBI showed the presence of a statistically significant difference (F = 34.63; p < 0.001), with a tendency for OHI-S to increase with an increase in the percentage of PBI-S. In examining the relationship between OHI-S and PBI, an extremely strong direct correlation was found (r = 0.923; p < 0.001). Conclusion: 1. PBI correlation analysis of OHI-S results showed a statistically significant difference. 2. The average value of OHI-S increases with an increase in the percentage of PBI-S.","PeriodicalId":93742,"journal":{"name":"Dental research and oral health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46344449","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}

Materials and Methods This retrospective chart review assessed data of patient hospital charts surgically treated for severe odontogenic infections in the operating room and admitted for greater than one day. Hospital charts of consecutive inpatients admitted from the ED to the University of Texas Southwestern Medical Center and Parkland Memorial Hospital for treatment from January 1 2016 to December 31 2020, were reviewed. Patients with infections of non-odontogenic origin were excluded. The specific outcome measures included total hospital stay cost, amount not collected, hospital charity adjustments, insurance type, length of stay, number of infected spaces, number of operating room visits, imaging ordered, and preadmission antibiotics. Results Data from 144 consecutive hospital charts were analyzed. The total billed cost of stay across all study years was $6,888,326.52, the average billed cost per hospital stay was $47,835.60, and the amount not collected was $2,864,857.82. Of the total billed cost, $2,107,692.15 was covered by hospital charity.

Conclusions Patients that are treated for severe odontogenic infections incur a large hospital bill that could have been avoided. Often, a very small percentage of this bill is collected by the hospital.","PeriodicalId":93742,"journal":{"name":"Dental research and oral health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69345638","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}
