Abstract

Nasopharyngeal carcinoma (NPC) is still a significant health problem due to its relatively high incidence. Rarely, NPC could extend and involve the oral cavity, and may present as an ulceration or exophytic mass. Objectives: To discuss the rare clinical appearance of NPC involving the oral cavity and the significant role of dentists in its diagnosis and management. Case Report: We reported 3 cases of NPC with oral cavity involvement. In the first two cases, the patients presented with persistent oral ulceration with bone exposure and perforation to the above structure. The third patient presented with an ulcerated exophytic mass with temporomandibular disorder. The ulceration occAurred due to bone destruction by the expansion of NPC mass, which indicated advance stage of the disease. All patients were managed with twice a day 0.2% chlorhexidine gluconate rinsing in combination with placing a chlorhexidine-moistened gauze to inhibit bacterial overgrowth and prevent secondary infection. The use of chlorhexidine was substituted by saline solution during patients’ radiotherapy and chemotherapy cycles. Conclusion: Dentist’s awareness to recognize the oral cavity involvement of NPC as well as recognizing the symptoms of NPC is very important, in order to make appropriate diagnosis and oral management. The oral management will eventually affect treatment outcome and quality of life.

Abstract

Mineral trioxide aggregate (MTA) as retrograde filling is always in contact to inflamed tissues in periradicular area. Objective: To investigate the effect of acidic environment on push-out bond strength of MTA mixed with sterile water, local anesthetic, and 5% CaCl2. Methods: Thirty middle third of mandibular premolar roots were randomly assigned into 3 groups of 10 each. MTA mixed with sterile water (Group 1), local anesthetic (group 2), 5% CaCl2 (group 3). Each group was then divided into group A: soaked in synthetic tissue fluid with pH 5, and group B: pH 7.4. Specimens were stored in an incubator with a temperature of 370C for 72 hours, undertaken a push-out test, and observed under a stereo-microscope. Results: A two-way ANOVA showed that acidic environment reduced the push-out bond strength of MTA mixed with either sterile water, local anesthetic or 5% CaCl2 (p <0.05). The predominantly failure was a mixture of adhesive and cohesive type. Conclusion: The acidic environment reduced the push-out bond strength of MTA mixed with either sterile water, local anesthetic or 5% CaCl2. MTA mixed with 5% CaCl2 produced the greatest push-out bond strength, whereas MTA mixed with local anesthetic had the lowest push-out bond strength.

Abstract

The traditional morphological concept to dental care has shown many drawbacks and is not appropriate in many cases. To counteract these shortcomings, a problem-solving approach has been introduced in dental curriculum of Cantho University of Medicine and Pharmacy (CTUMP), Vietnam. This approach should be reflected in dental practice in CTUMP. Objective: To investigate the problem-solving approach to dental care of CTUMP by patterns of tooth extraction, and tooth rehabilitation. Methods: Cross-sectional data on DMF, dental treatments planned, dental treatments delivered from 1549 dental records of patients aged ≥18 of CTUMP were analyzed. Results: The majority of patients were aged 18-29 (929, 60%), classified as professional and skilled workers (1112 subjects, 72%), lived in urban areas (1156 subjects, 75%), and women (932, 60%). The number of teeth eventually receiving dental treatment was lower than the number of teeth indicated for the treatment. On average, each patient had 2 teeth receiving treatment. Tooth restoration was the most common treatment (1390, 70%). Molars were the most treated teeth (842, 43%). Molars showed statistically significant higher chance for restoration and extraction than premolars and anterior teeth (Wilcoxon-signed-ranks test p ≤ 0.017). No statistically significance was found in tooth replacement between premolar and molar regions. The dental treatments aimed to preserve all teeth regardless of dental regions. Tooth replacement may tend to be morphologically based rather than functionally as most prostheses restored the complete dental arch. Conclusions: The approach to dental care in CTUMP tends to be morphologically conservative.

Abstract

Objective: This study aimed to determine the level of oral health literacy and behavior among health sciences university students. Methods: The method used descriptive cross-sectional survey involving 609 students from Faculty of Medicine, Dentistry, Pharmacy and Allied Health Sciences in the Universiti Kebangsaan Malaysia. Oral health literacy level and behaviour was assessed with a validated and pretested self-administered questionnaire using the Newest Vital Sign (NVS) tool and modified Oral Health Adult Literacy Questionnaire (OHL-AQ). Results: A total of 509 participants involved in the study (83.6%). The overall mean oral health literacy score was 10.27 (95% CI 7.92, 12.62), which found dental students showing statistically significant higher scores (mean=11.36, 95% CI 9.70, 13.02) compared to medical (mean=10.72, 95% CI 8.67, 12.77), allied health sciences (mean=9.89, 95% CI 7.34, 12.44) and pharmacy (mean=9.55, 95% CI 7.23, 11.87). Almost all respondents are non-smokers (99.8%) and non-drinkers (97.2%). Only 19.1% pay regular dental visits every 6-12months while 51.1% visit dentist only when they have dental pain. There appears to be a positive relationship between oral health literacy and oral health behavior. Conclusion: Health science university students should be provided substantial dental health education in their curriculum as they could be potential strategic partners in oral health.

Abstract

Medication-Related Osteonecrosis of the Jaw (MRONJ) therapy remains an unresolved problem. The proposed conservative and surgical treatment regimens are associated to contradictory success rates. Surgical approach with Er:YAG laser is associated to significant better results compared to medical treatment and traditional surgical approaches. Objective: To describe a new surgical approach that couples the advantages of the Er:YAG laser and the usefulness of the AF in highlighting surgical margins. One of the difficulties encountered during surgical removal of a MRONJ is the precise individuation of necrotic bone margins. Case Report: A case of Stage III mandibular osteonecrosis treated with a new surgical approach is presented. The aim is to describe an auto-fluorescence (AF) guided surgical approach performed with Er:YAG laser and Nd:YAG Low Level Laser Therapy (LLLT). After one month of follow-up, the complete mucosal healing was evident and symptoms was unobserved. Such a technique allowed a highly accurate and minimally invasive approach through the selective ablation of the non-/hypofluorescent areas. Conclusion: Taking into account the advantages of laser therapy and the possible effectiveness of the AF in highlighting surgical margins, this approach would probably achieve excellent outcomes.

Abstract

Research on the impacts of the ‘requirement system’ on student learning is still rare, however the system is still widely applied by Dental Schools in many countries. The major consequent of this system is the unpreparedness of students’ learning prior to presenting patients with particular complaints. Objective: This study aimed to explore the effect of the ‘requirement system’ on students’ learning strategy in Dental Education University of Jenderal Soedirman, Purwokerto, Indonesia. Methods: This was a qualitative-phenomenography study. The collection of data was through observations and interviews. The number of subjects was 13 students of the same batch in a clinical education level, determined by purposive sampling. Observations by 2 clinical teachers were done in advance and lasted for six weeks, followed by in-depth interviews. The analysis followed the phenomenography method. Results: Interviews revealed that application of the ‘requirement system’ had prompted the students to get the patients and to learn or not learn correspondingly to the specified cases. Students will have adequate preparation to learn if they are motivated to discuss with the teachers, having previous experiences, and if the patient is perceived to be special. Inadequate preparation of learning occurred when students felt tired, insufficient time between patients’ arrival and presentation in front of clinical teachers, and repetition of the case. Observations revealed that preparation for learning did not consequently lead to students’ performance in doing clinical work. ‘Well-done’ up to ‘less than expected’ performances were found in both single-cases as well repetition-cases. Conclusion: ‘Requirement system’ driven students’ preparation for learning. However, number of cases did not. Modifying the ‘requirement system’ and improving the quality of clinical supervision are two important things suggested by this study

Abstract

Pseudomonas aeruginosa is a Gram negative bacterium that can cause fatal infection in immunocompromised patient. This is an opportunist pathogen which is associated with some dental infections. Pseudomonas aeruginosa produces pyocyanin that functions as an important virulent factor in bacterial invasion. It can be identified in the lesion tissue and capable to induce cellular damage in endothelial cell, respiratory, neutrophil, and lymphocytes. B lymphocyte plays a significant role in the immune response of periapical infection; however, its cellular and molecular response to pyocyanin is unclear. Objective: To investigate cellular responses of B lymphocyte to the exposure of pyocyanin and the role of caspase-3 in its molecular mechanism. Methods: B lymphocytes (Raji cells) were cultured, and in five replications were exposed to various concentrations of pyocyanin for 24 h. MTT assay was performed to analyze the cytotoxicity effect of pyocyanin. Cell morphological analysis using phase contrast microscope were done in separate experiments. Immunocytochemical analysis was carried out for the identification of active caspase-3 protein expression, to study the mechanism involved in pyocyanin-induced cellular damage, Results: It showed that cell viability was decreased in pcyocyanin-treated groups. Pyocyanin induced cell death on B lymphocyte in a dose-dependent manner. Statistical analysis using ANOVA demonstrated significant difference between groups with p=0.000. Nuclear fragmentation was observed in pyocyanin-induced cell death; furthermore, caspase-3 was expressed clearly in cell cytoplasm after 24 h incubation. Conclusion: Pyocyanin is capable of inducing cell death on B l

Abstract

In recent years, national medical expenditures have continued to increase in Japan, and have now reached 39 trillion yen. In contrast, dental clinic expenditures have been slow to grow over the past few years, totaling 2.7 trillion yen. At the same time, the number of dentists continues to increase, with a total of 102,551 dentists in 2012, surpassing the 100,544 physicians at medical clinics. Objective: Given this, we compared management conditions at dental clinics and medical clinics over time to determine whether management conditions of dental clinics are really as harsh as often claimed. Methods: We used the relevant data provided in the Central Social Insurance Medical Council’s Survey on Economic Conditions in Health Care for statistics, which depicts management conditions at clinics, and analyzed the causes. Results: Annual fluctuations in the revenue/expense gap (revenue less expense) show that the gap for dentists far undercut that for physicians at medical clinics. The main reason for this decline in revenue is that the number of dental patients declined more than the unit price rose compared to the medical clinic. Conclusion: We determined that management conditions are harsh for dental clinics.

Abstract

Objectives: The objective of the study were to determine if there was any (bisphenol A) BPA release from three adhesive brands, to determine the differences of BPA release between three adhesive brands, to determine the genotoxicity from three adhesive brands, and to determine the correlation of BPA release and genotoxicity. Methods: Three branded adhesives materials were polimerized in mold and immersed in pH 7 and 4 artificial saliva from 24 to 720 hours. The artificial saliva was tested with spectrophotometry test to see BPA release at 24, 240, 480, and 720 hours, then freeze dried to get solid extract. Combination of the extract and lymphocite culture (male and female) then tested with in vitro cytokinesis-block micronucleus (MN) assay to see genotoxicity level of three adhesives at 24, 240, 480, and 720 hours as well. Results: The BPA release occured at 720 hours by Adhesive 1: 0.013μg/L; Adhesive 2: 0.11μg/L; Adhesive 3: 0.036μg/L. There was a statistically significant difference between BPA release with time (F = 505.98; p=0.00) and brands (F = 147.65; p = 0.00). Time and BPA release interaction also showed a statistically significant difference (F=13.35; p=0.00). Genotoxicity can be seen at 720 hours on Flowtain LV sample (MN frequency: male: 0.044; female: 0.053). Conclusion: The number of BPA release of all brand can be seen from the first 24 hours, and were increasing from 24 to 720 hours. Genotoxicity can be seen from one of the adhesive brand at 720 hours.There was correlation between BPA leaching and micronucleus frequency

Abstract

Special needs patients (SNP) have diffculty accessing dental services, partly due to reluctance of dentists to treat them. Objective: We assess didactic and clinical training experiences of fnal-year dental students and new graduates in managing SNP. Methods: An online questionnaire was sent to 123 fnal year dental students and new graduates, assessing their experiences and readiness in handling SNP. Results: Majority of the respondents were not confdent in attending to SNP. Majority gained knowledge in handling SNP via lectures while more than half had managed patients with complex medical history. Majority mentioned a lack of clinical training to treat SNP as their dental training experience had only been in a dental school clinical setting. Most of the respondents hope their curriculum would include more education to improve clinical skills in managing SNP. Conclusion: Respondents demonstrated minimum training and lack of confdence and skills that might contribute to a lack of preparedness to manage the oral health care needs of SNP. Clinical exposure in managing SNP at the undergraduate level is still inadequate and it needs to be emphasized in the curriculum
