Association Between use of Interdental Cleansing Aids Gingival Conditions in Fixed Dental Prosthesis Patients.

Background The fixed dental prosthesis are one of the most commonly used prosthesis which are difficult for cleansing in dental clinical practice especially the interproximal areas. As a result, periodontal disease most commonly develops in interproximal areas. The efficacy of using dental floss and interdental brushing in addition to tooth brushing reduce plaque and gingival inflammation. Objective To assess gingival condition in patients after placement of fixed dental prosthesis for a period of 3 months who regularly use or do not use dental floss and interdental brushing. Method Patients visiting the Dental Outpatient Department of Dhulikhel Hospital were selected for study. The examination was conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). The total number of patients involved in the study were 200. Teeth and gingiva were examined using the Plaque (Silness and Loe) and Gingiva Index (Löe and Silness). The examinations were conducted after 15 days and 3 months of placement of fixed dental prosthesis along with the oral hygiene instructions. Chi-square test and McNemar Bowker test were done to find statistical association using SPSS 20.0. Result Statistical analysis showed that there was association between frequency of interdental cleaning and plaque index (p=0.012) and gingival index (p=0.036) examined in 15 days and 3 months. Conclusion Use of Interdental cleansing aids was statistically significant to oral hygiene outcomes i.e. plaque index and gingival index. Oral hygiene instructions play a vital role in improving overall oral health.

Assessment of Level of Expectation and Awareness towards Dental Implants among Complete Denture Patients and Partial Denture Prostheses Wearers.

Background Among many options to replace missing teeth, dental implant is widely popular but willingness to have implant treatment and its success depends on patients' knowledge and expectations as well as the care, skill, and judgment of clinicians. Objective The main objective of this study was to assess awareness, expectation and source of information about dental implant among complete and removable partial denture wearers and to find association between them. Method A questionnaire consisting of 6 close-ended questions was used to assess the level of knowledge and awareness among patients visiting Dental Outpatient Department of Dhulikhel Hospital regarding dental implants as a treatment option for replacing missing teeth. Chi-square test was used to study the association between demographic variables and awareness about implantation. Statistical software SPSS 20.0 was used for data analysis. Result Our results revealed significant difference in age (p=0.001), education level (p=0.03) and occupation (p=0.004) in awareness of dental implant and no significant difference in gender (p=0.567), compared between complete and removable partial denture wearers. Due to lack of awareness, lower educational status and advanced age the patients responded that they "did not know " in answer to almost all the questions. Conclusion The awareness level of dental implant was low among complete and removable denture patients and this was associated with a low level of education and lack of accurate information about dental implants.

Full Coverage Crowns and Resin-bonded Bridge Combination for Missing Mandibular Anterior Teeth.

Most often the anterior teeth and those that are visible when a patient speaks or smiles are chosen for esthetic restorations. The mandibular anterior fixed bridge often presents problems to the dentist due to the size of the natural teeth and their visibility. In addition, due to high cost factor, many patients are not able to afford fixed partial denture for missing anterior teeth. This article describes a cost effective technique for the restoration of missing mandibular anterior teeth by fabrication of full coverage crowns and resin-bonded fixed bridge combination.

Oral Hygiene and Gingival Health in Patients with Fixed Prosthodontic Appliances - A Six Month Follow-up.

Background Gingival inflammation and periodontal disease are the common complications of fixed dental prosthesis. They can be overcome by good oral hygiene maintenance. Objective The objective of this study was to assess the oral hygiene and gingival condition in patients after placement of fixed dental prosthesis for a period of six months. It was also analyzed how factors like type of fixed dental prosthesis (Single crown, fixed partial denture) and material (Metal, Porcelain fused to metal) are statistically associated with oral hygiene and gingival health. Method The sample consisted of 50 patients visiting the Dental Outpatient Department of Dhulikhel Hospital. The oral examinations were conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). Teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe. The examinations were conducted after 14 days and six months after placement of fixed dental prosthesis along with the oral hygiene instructions. Paired sample t-test were done to find statistical association using SPSS 16.0. Result Our results revealed no significant difference in plaque index among patients with single crown whereas fixed partial denture showed statistical significance. No significant differences were found for type of material. The statistical analysis showed similar results for gingival index. Conclusion Our research showed that single crown had no significant difference on Plaque index and Gingival index of the patient after 14 days and six months, whereas, Fixed partial denture showed significant difference. Both metal and porcelain fused to metal crown revealed no statistically significant difference on Plaque index and Gingival index.

Etiology and antimicrobial susceptibility pattern of bacterial pathogens from urinary tract infection.

Urinary tract infection (UTI) is the most common infection in both community and hospital patients. In majority of the cases, empirical antimicrobial treatment is practiced before the laboratory results of urine culture. Thus, antibiotic resistance may increase in urinary bacterial pathogens due to improper use of drugs. This study was designed to find out the etiological agents of UTI and their prevalence, and to determine the antimicrobial susceptibility pattern of the bacterial pathogens isolated from urine culture. This study was conducted in Kathmandu Model Hospital, Kathmandu, Nepal from April to October, 2009. Midstream Urine samples from 1323 patients suspected of UTI were analyzed by microscopy, and conventional semi-quantitative culture technique for the significant growth. Antimicrobial susceptibility test was performed for the isolates by Modified Kirby-Bauer disk diffusion method. Data were analyzed using SPSS software window version 16. The overall prevalence of UTI was found to be 18.89%. The most frequent causative organisms isolated were Escherichia coli (82.30%), Enterococcus faecalis (5.60%), Citrobacter freundii (3.60%), Enterobacter aerogenes (2.40%), Coagulase Negative Staphylococci (2.40%), Pseudomonas aeruginosa (1.20%), Proteus mirabilis (0.8%), Klebsiella pneumoniae (0.4%), and Staphylococcus aureus (0.4%). Nitrofurantoin and Amoxycillin were found to be the most effective antibiotic against gram negative and gram positive isolates respectively. E. coli was found to be the most common etiological agent of UTI and Nitrofurantoin was the most effective drug among the isolates.

Prevalence of vaginitis among pregnant women attending Paropakar Maternity and Women's Hospital, Thapathali, Kathmandu, Nepal.

Vaginitis is the most prevalent disorder among the pregnant women. The objective of this study was to find out the prevalence of common types of vaginitis among the pregnant women visiting Paropakar Maternity and Women's Hospital in Kathmandu. Among 200 pregnant women included in the study, 78 (39.0%) had vaginitis. Of total 78 positive cases of vaginitis, 29.5% had candidiasis, 52.6% bacterial vaginosis and 1.3% trichomoniasis. Approximately 83% had monomicrobial infection and 16.7% had polymicrobial infection. Vaginitis was common in the age group of 20 to 29 years (41.8%) and 30-39 years (40.0%). Ethnically, Indo-Aryans (40.2%) were mostly infected. The infection rate was the highest among illiterate women (47.6%) and least among the women having education above secondary (23.0%). The positive infection rate was higher in women from rural area (45.2%) than those from urban area (37.3%). Nearly half of the women with agriculture occupation (48.4%) had vaginitis. Vaginitis was common in women with third pregnancy (52.6%). Among 78 vaginitis cases, 53 (67.9%) were asymptomatic cases.

Antibiotic susceptibility patterns of Vibrio cholerae isolates.

INTRODUCTION: Cholera is one of the most common diarrhoeal diseases in Nepal. Etiological agent of cholera is Vibrio cholerae which removes essential body fluids, salts and vital nutrients, which are necessary for life causing dehydration and malnutrition. Emerging antimicrobial resistant is common. The aim of the present study was to determine the antibiotic susceptibility pattern of cholera patients in Nepal. METHODS: All the laboratory works were conducted in the bacteriology section of National Public Health Laboratory, Teku from March to September 2005. During this period a total of 340 stool samples from diarrhoeal patients were collected and processed according to the standard laboratory methods. Each patient suffering from diarrhoea was directly interviewed for his or her clinical history during sample collection. RESULTS: A total of 340 stool samples were processed and studied from both sex including all ages of patients. Among the processed sample 53 Vibrio cholerae cases were found. All isolated Vibrio cholerae O1 were El Tor, Inaba. All isolated (100%) Vibrio cholerae O1 were sensitive to Ampicillin, Ciprofloxacin, Erythromycin and Tetracycline whereas all were resistant to Nalidixic acid and Cotrimoxazole. Only 15.1% cases were sensitive to Furazolidone whereas 84.9% were resistant. CONCLUSION: All V. cholerae strains isolated in this study were found resistant to Multi Drug Resistant (resistant to at least two antibiotics of different group). Ampicillin, Ciprofloxacin, Erythromycin and Tetracycline were found still more potent antibiotics against Vibrio cholerae isolated during the study.
