The B.S.S.O. M.Orth. Prize of the Royal College of Surgeons of England 1998

Abstract

Aim: To determine the relationship between treatment need assessment scores of orthodontists, general practitioners, and pediatric dentists.

Study design: Observational.

Sample: Ten general dental practitioners, 18 orthodontists and 15 pediatric dentists reviewed 137 dental casts and recorded their opinion on whether orthodontic treatment was needed.

Results: We found a high level of agreement between pediatric dentists, orthodontists and general practitioners (Kappa range 0.86–0.95). Between the groups, the amount of agreement was lower.

Conclusions: Orthodontists, general dental practitioners, and pediatric dentists in this sample exhibit high levels of agreement on orthodontic treatment need.

The B.S.S.O. M.Orth. prize of the Royal College of Surgeons of England: 1997.

Abstract

Objectives: To test the use of Moyers prediction method and Tanaka and Johnston’s equations for use in a Nepalese population and to construct new probability tables and prediction formulae based on the actual tooth sizes in a sample of the Nepalese population.

Design: Cross-sectional.

Source and setting: Dental, medical and nursing science students at the B.P. Koirala Institute of Health Sciences, Dharan, Nepal.

Subjects and methods: The sample consisted of 100 Nepalese males and 100 females aged between 17 and 23 years. Subjects without any previous orthodontic treatment, fully erupted permanent teeth and with no dental anomalies were recruited. Dental study models were taken and measurements of the mesio-distal widths of teeth were carried out using digital caliper. The measured values were compared with predicted values derived from Moyers method and Tanaka and Johnston equations. Independent t tests were used to examine differences between genders. Correlation coefficients and linear regression equations were used to compare the actual Nepalese tooth widths with predicted values

Results: Moyers method at 50% tends to underestimate the actual width of the canine and premolars in males by 0.3 mm and overestimate the width in females by 0.2 mm. The Tanaka and Johnston method tends to overestimate the actual width of the canine and premolars in both males (0.7 mm) and females 1.0 mm.

Conclusion: The newly developed regression equations are more accurate for prediction of width of unerupted permanent teeth in a Nepalese population. Further studies are required based on larger sample size, to confirm the applicability of the new regression equations proposed.

The William Houston Gold Medal Prize in the M.Orth. Exam of the Royal College of Surgeons of Edinburgh Held in Edinburgh, 2000

Abstract

Prepared samples of light-activated composite were cured by transillumination of tooth tissue in healthy volunteers. Positioning of the samples and the direction of illumination was designed to simulate curing during direct bonding. The effectiveness of curing was investigated by determination of surface microhardness. The degree of polymerization of the specimens cured by transillumination was found to be reduced compared to the control samples cured by direct exposure to the light source.

Abstract

The literature on the psychological effects of a cleft lip and/or palate is considered within the context of findings on facial abnormalities in general and the relationship between appearance and attitude formation. It is suggested that predictions from the general to the particular case of the cleft child are not always in the direction that might be anticipated, for there is little evidence of specific or severe psychological sequaelae to clefts. Nevertheless, there are indications of possible areas of difficulty and an outline for further research is put forward.     

The Gold Medal of the Conjoint M. Orth. Examination of the Royal College of Surgeons of Edinburgh and the College of Dental Surgeons of Hong Kong,Surgical Orthodontic Cases

Abstract

The Conjoint Gold Medal was awarded to the candidate who scored the highest overall mark in Part II of the Membership of Orthodontics examination held by the Royal college of Surgeons of Edinburgh and the College of Dental Surgeons of Hong Kong. It is the intermediate examination for the orthodontic specialty training pathway in Hong Kong. Part of this examination involved the presentation of a fully documented fixed appliance case and a multidisciplinary case, and three other cases with condensed case histories. This article described two surgical orthodontic cases presented during the 1999 and 2002 examinations by the award winners.

Assessment of clinical case presentations for the Membership in Orthodontics, Royal College of Surgeons of England 1995, 1996.

The cases presented and treated at successive examinations by the candidates for the Membership Examination in Orthodontics in 1995 and 1996 at The Royal College of Surgeons of England, were of a very high standard and demonstrated a wide range of treatment modalities. All cases had fixed appliances, predominantly with pre-adjusted Edgewise appliances. IOTN confirmed that most cases were in great need of treatment, with PAR scores showing them to be treated to a high standard.     

The John Kay Williams Gold Medal of the Royal College of Surgeons of England and Glasgow 2015

This paper describes the clinical treatment of two cases presented by the recipient of the 2015 Bi-collegiate Membership in Orthodontics John Kay Williams Gold Medal of the Royal College of Surgeons of England and Glasgow. The first case describes the management of an 11-year-old male with a class II Division 1 malocclusion with a 9?mm overjet complicated by an upper anterior odontome and moderate upper arch crowding. The second case describes a 14-year-old female with a class III malocclusion with a reverse overjet complicated by moderate lower arch crowding and previously removed upper permanent canines.     

The future of academic surgery--a consensus conference held at the Royal College of Surgeons of England, 2 September 2005

A consensus conference organised by the Association of Surgeons of Great Britain and Ireland (ASGBI) and the Association of Surgeons of Training (ASIT) was held at the Royal College of Surgeons of England on 2 September 2005. All Specialist Advisory Committees and specialist associations were represented, except for orthopaedic surgery. The future of both academic surgery and training were discussed. We concluded that the European Working Time Directive, and Modernising Medical Careers are likely to have an adverse effect on future of research in oral and maxillofacial surgery. Most surgeons were concerned about the future of training and the development of surgery in general.

钛的氧化行为对钛瓷结合力的影响

目的:观察钛的氧化行为对钛瓷结合力的影响。方法:铸造28mm×3mm×0.5mm的纯钛试件24个,喷砂、清洗后分为4组,每组6个,第1组不进行预氧化处理,第2、3、4组分别在750、800、900℃温度下,在烤瓷炉内进行预氧化处理5min。于每个金属试件中份8mm×3mm处,依次熔附Noritake TI-22瓷系统的黏结剂、遮色瓷、牙本质瓷,瓷层总厚度1mm。在拉伸试验机上采用三点弯曲法测试金瓷分离时的加载值。使用薄层X线衍射仪观察4组试件未附瓷的钛表面氧化膜中氧化物的种类。结果:不预氧化、750、800、900℃预氧化试件的金瓷分别加载(N)测试结果为10.33、9.98、5.53、3.37。不预氧化试件表面氧化膜中的氧化物全部是Ti6O;750、800、900℃试件的氧化膜中的氧化物为Ti6O和TiO2,900℃试件氧化膜中的TiO2的量明显增加。结论:随着氧化温度的升高,氧化膜中TiO2含量明显增加,钛瓷结合力显著下降,说明钛的高温氧化行为对钛瓷结合力有不利的影响。
