Evaluation of the quality of fixed prosthesis impressions in private laboratories in a sample from Yemen

Abstract Background Fixed prosthodontics require an accurate impression for the teeth and the area to be restored for the laboratory to fabricate the desired restoration without mistakes. This study evaluated the quality of impressions received by private laboratories for the fabrication of fixed prosthesis by describing the frequency of clinically detectable errors and by analyzing association between the various factors involved. Methods 165 impressions were collected from four dental laboratories. Jaw involved, type of tray, size of tray, number of prepared units, type of impression materials, techniques and viscosity in case of elastomeric impressions and type of prosthesis requested were recorded. Data referring to errors and visible defects including errors in finish line, in preparation area, in silicone impression technique and blood in impression were also documented. Factors affecting errors present were also assessed. Association between dentist gender and experience years and impression errors was assessed. Chi square and Fisher exact tests used to examine the association between categorical variables and outcomes. Results The total of error considering not immediately pouring as an error. Alginate was the most impression used. of impressions evaluated (50.9%), 97% were have at least one visible error; 92.1% had errors in finish line, 53.9% had errors in preparation area and (72.8%) of elastomeric impressions were have at least one error in technique. Blood in impression was detected in 52.1% of impressions. Significant association was found between material type and errors in finishing line and preparation area. Significant relationships were found between gender and errors in silicone impression technique (p < 0.05). Conclusion Within the limitations of this study, high frequency of detectable errors was found in fixed prosthesis impressions received by private dental laboratories. This high frequency is of serious concern, as this will result in poor fitted fixed prosthesis provided to patients.

There is variation in fixed prosthodontics practice and many studies have concluded that clinicians definitely deviate from the recommended clinical protocols. If this happens during treatment with fixed prosthesis, the quality of fixed prostheses is compromised which affects it’s long term survival. Therefore, the aim of this study was to evaluate the use of impression materials and techniques in fixed prosthodontics among Nepalese dentists and to compare the findings on the basis of educational level and years of experience. A cross-sectional, questionnaire-based online survey was done amongst the Nepalese Dentists through google forms. Data from the completed questionnaires were analysed using the SPSS version 16. All statistical analyses were carried out at a significance level of P < 0.05. Out of 129 participants, 68 (52.7%) dentists often made diagnostic impression for fabrication of study cast. 85(65.9%) dentists used Addition silicone, 11(8.5%) used Condensation silicone and 33(25.6%) used Alginate for final impression making. Most commonly used elastomeric impression technique was Putty Wash single stage (56.2%), 40.7% used Putty Wash two stage, 3.1% used Single mix (Monophase) technique. Regarding retraction cord, 63.5% of dentists used Plain gingival retraction cord and 35.7% of dentists used Chemical impregnated retraction cord. Conclusion: The study found that most of the responses on use of impression materials and techniques were significantly associated with the level of education and clinical experience.

Abstract Introduction Poor handover between shifts can result in patient harm. This study was designed to evaluate the impact of implementing a handover protocol on the quality of information exchanged in the trauma handover meetings in a UK hospital. Method A prospective single-centre observational study was performed at an NHS Trust. Ten consecutive weekday trauma meetings, involving 43 patients, were observed to identify poor practices in handover. This data was used in conjunction with the Royal College of Surgeons’ recommendations for effective handover (2007) to create and implement a standard operating protocol (SOP). Following its implementation, a further 8 consecutive meetings, involving a further 47 patients, were observed. The data was analysed using t-test for quantitative variables and chi-square or Fisher’s exact tests for categorical variables. Results An improvement was demonstrated in multiple aspects of trauma handover including past medical history, injury date, results, diagnosis, consent, mark, and starvation status (all p < 0.001). Subgroup analyses showed that handover of neck-of-femur fracture patients including information on baseline mobility (p = 0.04), Nottingham-Hip-Fracture Score (p = 0.01), next-of-kin discussion (p = 0.075) and resuscitation status (p = 0.001) all improved following the intervention. Conclusions These results demonstrate that the implementation of a well-structured handover protocol can improve the transmission of critical information in trauma meetings.

Patients in health services have different behaviors in deciding to take advantage of health services. Patients used various considerations to make decisions based on the health products or services for re-treatment. The study aimed to analyze the factors that influence the patient's decision in using health services for re-treatment. This research was quantitative with cross-sectional design and conducted at Tanjung Pura Regional Hospital. The population was 3.946 people, and the sample were 247 respondents taken by using purposive sampling. Data analysis was univariate and bivariate using chi-square and multivariate using multiple logistic regression at the 95% confidence level (a= .05). The results showed that the factors that influenced the patient's decision to use health services for re-treatment at the Tanjung Pura Regional Hospital were the service quality of doctors / nurses (p= .000), distance (p=.049), facilities (p=0.000), and service speed (p = .000). The factors that did not influence we age (p=.461). gender (p=.895), education (p=.371), occupation (p=.593). The most dominant factor influencing is facilities with Exp (B)/OR =14.477, meaning that respondents who stated that the hospital facilities were good, had the opportunity to use health services for re-treatment by 14.4 times higher the respondents who stated that the hospital facilities were not good. It is suggested to Tanjung Pura Regional Hospital to propose and allocate a budget for improving hospital facilities that are still lacking and adding new service facilities so that it can increase public confidence for repeat treatment

The advent of new technologies in the field of medicine and dentistry is giving improvements that lead the clinicians to have materials and procedures able to improve patients’ quality of life. In dentistry, the last digital techniques offer a fully digital computerized workflow that does not include the standard multiple traditional phases. The purpose of this study is to evaluate all clinical trials and clinical randomized trials related to the digital or dental impression technique in prosthetic dentistry trying to give the readers global information about advantages and disadvantages of each procedure. Data collection was conducted in the main scientific search engines, including articles from the last 10 years, in order to obtain results that do not concern obsolete impression techniques. Elsevier, Pubmed and Embase have been screened as sources for performing the research. The results data demonstrated how the working time appears to be improved with digital workflow, but without a significant result (P = 0.72596). The papers have been selected following the Population Intervention Comparison Outcome (PICO) question, which is related to the progress on dental impression materials and technique. The comparison between dentists or practitioners with respect to classic impression procedures, and students open to new device and digital techniques seem to be the key factor on the final impression technique choice. Surely, digital techniques will end up supplanting the analogical ones altogether, improving the quality of oral rehabilitations, the economics of dental practice and also the perception by our patients.

Tuberculum Sellae

ABSTRACT Context: Tuberculum sellae meningiomas have proved difficult to treat, partly because of their intimate association with the optic nerves and chiasma, hypothalamus, and internal carotid arteries. Aims: The aim of this study is to analyze the degree of influence of various prognostic factors affecting visual outcome; the pattern of visual recovery and develop a scoring system for prognostication. Settings and Design: This is a retrospective study carried out from January 2004 till June 2011. Materials and Methods: Patients were analyzed on the basis of clinical, radiological, and surgical factors that appeared to affect the outcome. A special scoring system (according to the guidelines of the German Ophthalmological Society) was adopted to quantify the extent of ophthalmological disturbances. Statistical Analysis Used: Comparison of categorical variables between the two was performed using chi-square test and a P value of ≤ 0.05 was considered significant. Logistic regression was used when multivariate analysis was required. Results: Vision improved in 27% and deteriorated in 7.3%. A prognostic scoring system (score 4–13) was developed depending on the degree of influence of significant prognostic factors. The patients with a score of ≤6 had improved vision postoperatively (44%), whereas none of those with a score > 6 improved. Completeness of visual recovery was perceived in 100% of patients within 3 months. Complete resectability was achieved in 73% of patients. Conclusions: The proposed scoring system is very useful in prognosticating the visual outcome of these patients. The patients with a score of ≤6 have the best visual outcome postoperatively. Complete resectability is better achieved with extended bifrontal and unilateral frontal approaches. Short-term postoperative visual outcome is a strong indicator of permanent visual outcome after surgery.

Introduction: Undergraduate (UG) dental students are trained for fixed prosthodontics course clinically in teaching institutions during the clinical years. However, there is a lack of objective data on the quality of fixed prostheses preparations done by UG students on their patients for academic and clinical staff. Aim: To evaluate the full-coverage crown preparations performed by UG dental students in the university clinical teaching programme. Materials and Methods: This study was a clinical audit done in the Faculty of Dentistry, Universiti Sains Islam, Malaysia (USIM) from April to July 2018. The demographic and clinical data were collected from the patients’ notes and included relevant information of patients such as age, gender and others. Full-coverage crowns were analysed and crown preparation assessments were done using specific criteria and standards. The descriptive data were measured in frequency and percentage for categorical variables and mean and standard deviation for continuous data. Results: A total of 31 patients fitted with 45 units of full-coverage crowns were analysed. The mean age of patients treated by fifth year dental students was 40.5 (±14.16) years. A 51% Porcelain Fused to Metal (PFM) crown provided to the patients. On the whole, UG undergoing the dentistry programme in the institution scored the lowest (51%) on proximal reduction and the highest (97.7%) on producing smooth and continuous preparation. Conclusion: Majority of the crowns prepared by students have acceptable preparation except in proximal reduction and cervical margin preparation that can be improved upon and emphasised further during the teaching and learning sessions.

Brachial Plexus Blockade

Introduction: Ultrasonography (USG) guided supraclavicular block is an excellent choice for upper limb surgeries. It not only allows smaller volumes of local anaesthetic usage but also provides optimal tourniquet coverage. Ropivacaine is structurally related to bupivacaine with reduced potential for toxicity and improved sensory and motor blocking profiles. Nalbuphine acquired a significant place in pain control but its efficacy as a local anaesthetic adjuvant is yet to be proved in peripheral nerve blockades. Aim: To evaluate the efficacy of adding nalbuphine to ropivacaine in supraclavicular brachial plexus blockade and to assess the quality of block for patients undergoing ambulatory forearm and hand surgeries. Materials and Methods: Seventy American Society of Anesthesiologists (ASA) grade 1 and 2 patients were randomised into two groups of 35 each. Group A (n=35): received 24 mL of 0.5% of ropivacaine + 1 mL of nalbuphine (10 mg) and Group B (n=35): received 24 mL of 0.5% of ropivacaine + 1 mL of normal saline. The parameters observed were duration of analgesia, onset of sensory and motor blockade, duration of motor blockade and haemodynamic changes during the procedure. Categorical variables were analysed using the Pearson’s Chi‑square test. Continuous variables were analysed using the independent sample t‑test and p<0.05 was considered as statistically significant. Results: The onset of sensory and motor blockades were faster in the nalbuphine group compared to the control group (p<0.001). The duration of sensory and motor blockades was similarly longer in nalbuphine group (p<0.001). Also, the mean duration of analgesia was significantly longer with nalbuphine group (p<0.001). Conclusion: Nalbuphine significantly prolonged the duration of analgesia and duration of block while accelerating the onset of blockade thereby improving the overall quality of blockade.

Medical Emergencies

Introduction: Medical emergencies can occur in dental practice anytime. Changing demographics in the population and increased life expectancy have resulted in more people having medical conditions which predispose to a medical emergency.Objective: To find the prevalence of medical emergencies in dental practice in Nepal, to assess the preparedness of dentists to manage emergency situation, to find out the ways to improve their preparedness, and to determine the factors affecting the occurrence of medical emergency.Materials & Method: A cross-sectional study using self-administered questionnaire was done among one hundred and twenty four participants present at the 16th Annual Dental Conference. The questionnaire consisted of 15 questions. The data were analyzed using chi-square test and cross tabulation was performed to evaluate categorical variables at a significant level of p< 0.05.Result: The percentage of respondents who reported at least one emergency situation was 37.1%. Majority of the events occurred during oral surgical treatment. According to the survey, the most frequently encountered emergency condition was vasovagal syncope followed by hypoglycemia and seizures. The emergency events were managed by the respondents through various modalities. The dental graduates despite BLS training were found to feel incompetent to manage emergency events.Conclusion: Medical emergencies in dental practice in Nepal are frequent and not as rare as anticipated. Thus periodic training should be provided to improve necessary clinical skills.
