Aim: The aim of this study was to determine the perception of clinical dental students and interns towards the specialty of prosthetic dentistry and also assess factors that may influence choice of prosthodontics as a future career.Materials and Methods: The study was a descriptive cross sectional study of clinical dental students and interns at the University of Benin and University of Benin Teaching Hospital. Questions focused on the perceptions and factors that influenced choice of the specialty of prosthodontics as a future career. Data was analysed using Statistical Package for Social Science (SPSS) version 17.0. The analysis was done using frequency distribution, cross tabulations, test of significance with chi square. P<0.05 was considered statistically significant.Results: A total of 122 respondents consisting of 21.3% penultimate students, 41.0% final year students and 37.7% interns returned filled questionnaires. Majority (93.4%) reported they know who a prosthodontist is and 91.8% agreed that there was a need for more prosthodontists in Nigeria. Less than half (35.2%) of the respondents felt that they were well prepared in prosthodontics and 77% thought they did not have enough exposure to prosthodontics. There was statistically significant association between respondents' perception of preparedness and exposure to prosthodontics and choice of prosthodontics as a future career.Conclusion: There is a need to improve dental students and interns' exposure and preparedness to prosthodontics.

Background: Assessment of blood pressure is the most common diagnostic procedure performed in the outpatient clinic. The purpose of this study was to compare the accuracy of the wrist-cuff electronic oscillometric device with the universally-accepted gold standard measurement made with Korotkoff sound technique mercury sphygmomanometer.Materials and Methods: This was a randomized, crossover study with a total of 60 subjects. All subjects were at least 30 years of age. Three blood pressure readings were recorded for each subject, two with a wrist-cuff device and one with a mercury sphygmomanometer by the secondary investigator. The order of the 3 readings were determined by chance.Results: Patients (32 women, 28 men) aged 30-94 (mean age = 55, SD =16) years were included in the study. Based on the paired-sample t-test, the data provided strong evidence that there was no statistically significant difference in systolic or diastolic blood pressure readings between the wrist-cuff electronic oscillometric device and mercury sphygmomanometer.Conclusions: The evaluation of blood pressure remains a basic diagnostic step in every clinical practice as it positively imparts the clinical well-being of the patient. It is, therefore, important to maintain a good degree of accuracy and reliability in the blood pressure monitoring device.

Objective: To describe the spectrum, frequency, age and sex distribution of ameloblastomas seen in Kano, as well as compare the findings with previous studies done in Nigeria, Africa and other parts of the world. Materials and Methods: This was a 5 year retrospective study from 2nd January, 2010 to 31st December, 2014 of all ameloblastomas diagnosed at the pathology department of Aminu Kano Teaching Hospital, Kano, Nigeria. Results: Sixty four cases of ameloblastomas were diagnosed during the five year study period with a male to female ratio of 2:1. The ages ranged from 16 to 75 years (mean age of 33.4) and relative peak age of incidence occurred in the 40 - 49 years group. Solid/Multicystic type accounted for majority (57 cases, 89.1%) of ameloblastomas followed by unicystic variant (5 cases,7.8%), while the desmoplastic and peripheral variants comprising the remaining 2 cases (3.1%). The mandible was the commonest site of involvement accounting for 57cases(89.1%), while maxilla and alveolar mucosa accounted for 6 cases (9.4%) and 1case (1.6%) respectively. Conclusion: This study showed that ameloblastoma has significant male predilection and affecting predominantly patients in the third to fifth decades. It revealed a higher incidence of solid/multicystic ameloblastomas over unicystic variants. The demographic and histological features are similar to reports from other parts of Nigeria and elsewhere.

Background: Dentistry is perceived as a highly stressful profession and the dental school is often where the stress begins. Contemporary dental curricula require students to attain diverse proficiencies such as acquisition of theoretical knowledge, clinical competencies, skills acquisition and best practices which add up to stress. The objectives were to identify the sources of perceived stress, and the coping strategies adopted by clinical dental students in two Nigerian Universities. Materials & Methods: A cross-sectional study involving all clinical students in the two oldest dental schools in Nigeria. A validated self administered, structured questionnaire comprising of the modified version of dental environmental stress survey(DES), the perceived stress scale and brief coping scale was used in collecting data from the participants. Results: The potential sources of stress which were most frequently reported were the academic factors with volume of learning rated highest (84.2%) followed by demanding curriculum (72.6%) and frequent formative and summative assessment (51.7%). Inadequate infrastructures and erratic power supply were considered the most frequent(70.7%, 67.6%) sources of stress among the physical and environmental factors. Workload was also a major concern for stress with requirement to perform specified types and number of procedures rating the highest(76.9%) followed by time limits(69.8%). More (47.8%) females pray/ meditate while 29.6% cry as a means of relieving stress while the males play games which are all statistically significant (p= 0.003, 0.001 and 0.000 respectively). Conclusion: The most frequently reported source of stress are the academic factors with volume of learning rated the highest followed by demanding curriculum and frequent examinations. The strategies adopted to cope with stress across the gender were praying and crying among females and playing games in males.

Dentinogenesis Imperfecta is a localized mesodermal dysplasia affecting both the primary and permanent dentition. First described in the late 19th century, it is characterized by discolored and translucent teeth ranging from grey to brownish-blue or amber. Dentinogenesis Imperfecta, type II (DGI-2) is rare and it is a severe form of the condition. Radiographically, the crowns of the teeth are bulbous with marked cervical constrictions, and the pulp chambers become obliterated over a period of time. Sensori-neural hearing loss has also been reported in some patients. This case report presents the restorative management of DGI-2 in a 44year old clergy woman whose primary complaints were poor aesthetics and lack of social acceptance. The case was managed with consideration of the patient's limited financial resources at the Lagos State University Teaching Hospital, Ikeja (LASUTH). The objective of the management of this condition was to open the bite of the patient using maxillary posterior bite plane followed by intermediate restoration of worn teeth using composite resin for the newly established occlusion. The patient used the restorations for a while before definitive restorations, using ceramo-metal crowns as well as over dentures, were carried out. The restorative treatments corrected the patient´s vertical dimension of occlusion with resultant acceptable aesthetics and function. The patient was satisfied with maxillary anterior ceramo-metal crowns and a posterior removable over denture as well as a complete mandibular over denture.

Background: Trigeminal Neuralgia (TN) is a frequent cause of paroxysmal facial pain and headaches in adults. It frequently presents in the fourth and fifth decade of life and affects the 5th cranial nerve. It is usually unilateral and does not disturb sleep. The gold standard drug is Carbamazepine (CBZ) and treatment failure to CBZ could be attributed to intake of drugs or food containing B group vitamins, patients' tolerance to the medication and the use of fake medication. The effectiveness of this drug has been reported but, there is dearth of literature that demonstrates causes of failure of CBZ in the treatment of trigeminal neuralgia.Objective: To determine the causes of treatment failure in Trigeminal neuralgia patients attending the Oral Medicine Clinic of Lagos University Teaching Hospital, Lagos, Nigeria.Materials and Methods: This was a retrospective study of cases of Trigeminal Neuralgia who presented at the Oral Medicine Clinic of the study institution between April 2009 and April 2012. Data were collated from patients' case notes and clinical records. The recorded parameters included patients' bio data, response to treatment and treatment failure. The results were analyzed using Statistical Package for Social Sciences for Windows(version 16).Results: A total number of 32 patients were diagnosed with Trigeminal neuralgia during this period. There were 22 (68.87%) females and 10 (31.2%) males; with female to male ratio of 2.2:1. Age range was 9 to 82years (mean 53.4±13.86). Carbamazepine was the principal drug prescribed. There was treatment failure associated with it due to the use of B group vitamins in 10 patients (31.5%); 5 (15.63%) from tolerance to the drug and 2(6.10%) from fake drugs. Twenty-seven (84.4%) patients went into remission when all the factors leading to failure were addressed; therefore the response rate was good.Conclusion: Carbamazepine was used as the primary drug in the treatment of trigeminal neuralgia and treatment failure was largely due to taking drinks and drugs containing B group vitamins.
背景:三叉神经痛(TN)是成人阵发性面部疼痛和头痛的常见原因。它经常出现在生命的第四和第五十年，并影响第五脑神经。它通常是单侧的，不影响睡眠。金标准药物是卡马西平(Carbamazepine, CBZ)， CBZ治疗失败的原因可能是摄入含有B族维生素的药物或食物、患者对药物的耐受性以及使用假药。该药物的有效性已被报道，但缺乏文献证明CBZ治疗三叉神经痛失败的原因。目的:探讨尼日利亚拉各斯大学教学医院口腔医学门诊三叉神经痛患者治疗失败的原因。材料和方法:本研究是对2009年4月至2012年4月在该研究机构口腔医学诊所就诊的三叉神经痛病例进行回顾性研究。数据整理自患者病例记录和临床记录。记录的参数包括患者的生物资料、治疗反应和治疗失败。使用Statistical Package for Social Sciences for Windows(version 16)对结果进行分析。结果:本组共32例患者诊断为三叉神经痛。其中女性22例(68.87%)，男性10例(31.2%);男女比例为2.2:1。年龄范围9 ~ 82岁，平均53.4±13.86岁。卡马西平是主要的处方药物。10例(31.5%)患者因服用B族维生素导致治疗失败;5名(15.63%)来自药物耐受，2名(6.10%)来自假药。所有导致失败的因素得到解决后，27例(84.4%)患者进入缓解期;因此，反应率很好。结论:卡马西平是治疗三叉神经痛的主要药物，服用含B族维生素的饮料和药物是治疗失败的主要原因。

Background: Excessive opening of the mouth has been reported to cause clinical problems such as luxations and traumatic injury to the temporomandibular joint (TMJ). The knowledge of the normal range of mouth opening will help to avoid excessive opening of the mouth which can cause injury to the TMJ of patients during procedures that involve mandibular manipulations. Maximum mouth opening (MMO) has age, race, gender and ethnic variations. Previous studies have looked at normal range of mouth opening among adults, but to the best of our knowledge, no study has looked at this among the paediatric/children population in Nigeria. Thus, this study aimed to determine the normal maximum mouth opening (MMO) among the paediatric population in Ibadan (South Western part of Nigeria) and the effect of gender, age, height and weight of these children on their MMO. Materials and methods: Six hundred and nine primary and secondary school pupils aged 6 – 15 years were included in this study. Patients with any condition affecting the temporomandibular joint (TMJ) function were not included. Measurements of height, weight and two readings of maximum interincisal distance were performed for each participant. Student's t-test, one-way analysis of variance (ANOVA) and Pearson bivariate correlation were used to assess the sample. Results: The mean MMO was 44.0 ± 5.3 mm and 42.6 ± 5.6 mm for males and females respectively. There was no significant difference in the MMO of males and females (t= 0.335, p = 0.563). MMO increases gradually with age irrespective of the gender and this was statistically significant (F= 17.1, p =0.001). Conclusion: The maximum mouth opening established for the paediatric population in this study will help practitioners whose care involves the stomathognathic system to have information about the normal range of mouth opening in this group of patients. The result will also be useful asbaseline for future research.
背景:据报道，过度张嘴会导致临床问题，如脱位和颞下颌关节(TMJ)的创伤性损伤。了解正常的开口范围将有助于避免在涉及下颌操作的手术过程中过度开口可能导致患者颞下颌关节损伤。最大开口(MMO)具有年龄，种族，性别和民族差异。以前的研究着眼于成年人的正常张嘴范围，但据我们所知，没有研究着眼于尼日利亚的儿科/儿童人口。因此，本研究旨在确定伊巴丹(尼日利亚西南部)儿科人群的正常最大张嘴量(MMO)以及这些儿童的性别、年龄、身高和体重对其MMO的影响。材料与方法:以69名6 ~ 15岁的中小学生为研究对象。不包括任何影响颞下颌关节(TMJ)功能的患者。测量每位参与者的身高、体重和两次最大内部距离读数。采用学生t检验、单因素方差分析(ANOVA)和Pearson双因素相关分析对样本进行评估。结果:男性和女性的平均骨密度分别为44.0±5.3 mm和42.6±5.6 mm。男性和女性的MMO差异无统计学意义(t= 0.335, p = 0.563)。与性别无关，随着年龄的增长，MMO逐渐增加，这具有统计学意义(F= 17.1, p =0.001)。结论:本研究中为儿科人群建立的最大张嘴量将有助于涉及口腔系统的医护人员了解该组患者的正常张嘴量范围。该结果也将为未来的研究提供有用的基础。

MMO increases gradually with age irrespective of the gender and this was statistically significant (F= 17.1, p =0.001). \u0000Conclusion: The maximum mouth opening established for the paediatric population in this study will help practitioners whose care involves the stomathognathic system to have information about the normal range of mouth opening in this group of patients. The result will also be useful asbaseline for future research. \u0000 ","PeriodicalId":79241,"journal":{"name":"Nigerian Dental Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41356562","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}
Papilliferous ameloblastoma is an uncommon histologic variant of ameloblastoma. About five cases have been reported in the English literature till date. All five showed squamous differentiation with keratin formation and were diagnosed as papilliferous keratoameloblastoma. The present lesion shows basaloid differentiation and mild dysplasia in addition to papilliferous projections, thus termed dysplastic papilliferous basaloid ameloblastoma. Ameloblastoma, the most common odostoma has not ceased to intrigue pathologists with its diverse histomorphological patterns. Therefore, we present this uncommon lesion in a 50 year old man with right mandibular swelling.

Objective: To audit the prescriptions sent by dental practitioners to the dental technicians for fixed dental prostheses.Methods: This was an audit of all written instructions for fixed dental prostheses sent to the advanced conservative dentistry laboratory of the University of Benin Teaching Hospital, Benin City, Nigeria. Data of interest were status of requesting dental surgeon, type of prosthesis, age of the patient, gender of the patient, next appointment date, disinfection status of the impression, metal alloy requested, design of the margin, number of pontics and design, surfaces to be covered by metal only, occlusal scheme, shade, diagram for illustration and the type of porcelain glaze.Results: Various types of fixed prostheses were requested with porcelain fused to metal single crowns accounting for more than half. The quality ofwritten instructions was clear only in 2.0% of the prescriptions while 56.8% had no instructions at all. There was no statistically significant relationship between the cadre of the dental practitioner making the request and the quality of written instructions. There was statistically significant association between types of prosthesis requested and provision of diagrammatic illustration on the written instruction.Discussion: Fixed prostheses are usually fabricated in the dental laboratory by dental laboratory technicians using impressions of the mouth made by dental practitioners. The quality of prosthetic restorations has been shown to be a reflection of the skills of the dentist and dental technicians as well as communication between them.Conclusion: There is need for improved quality of written communication between the dentists and the laboratory personnel.
