Eagle's syndrome: lesser cornu amputation: an alternative surgical solution?

A case is reported of a 42-year-old female patient, who presented with clinical symptoms of Eagle's syndrome, radiographic evidence of marginally elongated styloid processes as well as markedly elongated lesser cornua of the hyoid. The symptoms were successfully treated by amputating the lesser cornua of the hyoid. The patient has now been asymptomatic for more than 6 years.     

硬皮病:口腔的表现

硬皮病为一种系统性胶原病。除皮肤外,还可累及胃肠道、心、肺、肾等器官;其特点为胶原增殖,血管壁有炎性改变及球蛋白沉积。硬皮病也可侵犯口腔及其周围组织,常使面部皮肤及舌体变硬,也可使软腭、喉、小唾液腺受累。X线片可见颌骨有改变与牙周膜增宽,文献报导牙周膜增宽可见于10—37％病人,但并不是所有牙增宽,其增宽程度并不一致,后牙大于前牙。颌骨之吸收可发生于喙突、升枝后缘及髁突。作者于17年内调查了21个女病人,年龄27—63岁,13个在50岁以上,病程为3—49年。其中17例(80％)有张口受限(张口度<4cm),20例诊断有牙周病,但只有13个牙     

Erratum to: ZURÜCKGEZOGEN: Belastungsmessungen nach der Miniplattenosteosynthese von Unterkieferwinkelfrakturen

Aims

The aim of this study was to evaluate the load resistance of mandibular angle fractures treated with a miniplate osteosynthesis according to Champy.

Material and methods

We evaluated 22 completely dentate patients with fractures of the angle in addition to 15 controls. An electric test procedure for the determination of the load resistance between the incisors, canines and molars was carried out 1–6 weeks after treatment.

Results

At 1 week postoperatively 90 N was registered between the molars while after 6 weeks this was148 N. This revealed only 31% and 58% of the maximal vertical load found in the controls, respectively.

Conclusion

The minipate osteosynthesis according to Champy offers a secure method in the treatment of mandibular angle fractures with sufficient stability. Maximum voluntary bite forces were not registered during the time of healing.      

Chronic idiopathic orofacial pain: I: What is the evidence base?

Chronic idiopathic orofacial pain is currently a problem for the specialists, but is this type of disorder peculiar to the face, and is there a role for the general dental practitioner? This article reviews the current understanding and management of medically unexplained syndromes and discusses their application in facial pain. A second article will merge this contemporary theory and clinical evidence into a management strategy, and stress the importance of early intervention in the primary care setting.

Commentary: Periodontal Treatment and Inflammation in Diabetes: Association or Causation?

The causal effect of periodontal treatment on systemic outcomes is unclear because even randomized controlled trials (RCTs) have conflicting results. Two models are proposed to explain the apparently conflicting findings from RCTs evaluating the effect of periodontal treatment on inflammation and systemic outcomes among individuals with type 2 diabetes.     

Woman and career: an unhappy marriage? A study model: dentistry

Women's participation in the professions is steadily increasing. This study is a quantitative assessment of male and female career patterns in dentistry and of the role of marriage in any gender gap. A 1997 survey explored the professional activity of Flemish dentists. There is no educational disparity between dentists, female dentists enter the profession on an equal footing with their male colleagues. Therefore any other career influencing factors reveal themselves relatively clearly. Dependent variable was income; independent variables were gender and marriage. Female dentists scored lower than male dentists in each career phase; marriage made no significant difference. However, marriage turned out to be an important positive factor in the career of male dentists. Women dentists marry significantly later and less than their male colleagues. Further research, also of a qualitative nature, is necessary to evaluate the professional and social impact of this substantial gender difference.

Nd:YAP激光与Er:YAG激光在口腔医学的应用现状

自20世纪60年代激光首次用于口腔学科的几十年来,激光在临床得到越来越广泛的应用。目前,应用于口腔疾病的激光器有很多种,每种激光器各有其优缺点。本文比较了Nd：YAP激光与Er：YAG激光在口腔临床中的应用现状。     

Masseteric hypertrophy?: preliminary report

We report radiological and histological investigations of a patient who presented with the masseteric hypertrophy. Sections of the patient's masseter muscles were also investigated using a series of histological techniques. The histological and morphometric analysis of the patient's masseter muscle showed numerous small fibres, which indicated that the masseteric enlargement was not the result of classic fibre hypertrophy. We suggest that the use of the term 'hypertrophy' in this condition may be misleading.

Dental ceramics: what's new?

The advances in dental ceramic materials and systems continue to be related to improvements in strength, fitting accuracy and aimed towards avoidance of the use of metal substructures both in posterior and anterior teeth. Many of the changes seen within the last few years have been associated with modifications to, and improvements of, existing techniques. These are considered in this paper, and ceramic post systems are also reviewed.
