Reduction of occult metastatic disease by extension of the supraomohyoid neck dissection to include level IV.

Background: Patients with clinically N0 necks will undergo elective removal of lymphatic tissue from levels I, II, and III as part of their routine surgical management. Level IV is omitted on the basis that there is negligible chance of containing significant occult disease. Evidence to support this approach is minimal, and the aim of this study was to increase the yield of metastatically involved lymph nodes by simply extending the supraomohyoid neck dissection (SOHND) to include level IV.

Premature exfoliation of primary molars related to the use of formocresol in a multivisit pulpotomy technique: a case report.

Since its introduction in 1904, formocresol has become one of the most widely studied dental medicaments. In the United Kingdom, it is the preferred primary tooth pulpotomy medicament of the majority of Specialists in Paediatric Dentistry. Reports of adverse effects resulting from its clinical use are rare.

Tooth agenesis: a report of missing molars in two generations.

A recent review has suggested that tooth agenesis is becoming more evident in society, though it is not known whether this observation is related to better detection methods and patient awareness or whether there is a real trend towards an increase in prevalence. In this paper we report developmental absence of permanent molars in two generations, and discuss the possible clinical implications of this pattern of tooth agenesis.

Increased primary tooth size in a 47,XXY male: a first case report.

Increased tooth size has previously been reported in association with Klinefelter syndrome. However, until now, this observation has been restricted to the permanent dentition. In this paper, we report increased mesio-distal width in the primary incisor and molar teeth of a 47,XXY male.

Oral and dental care in acute lymphoblastic leukaemia: a survey of united kingdom children's cancer study group centres.

Objectives: To examine the provision of oral and dental care for children receiving treatment for acute lymphoblastic leukaemia (ALL) in United Kingdom Children's Cancer Study Group (UKCCSG) centres.

Sample And Methods: A postal questionnaire was sent to a named consultant at each centre. All 22 centres responded.

Avulsed permanent incisors: knowledge and attitudes of primary school teachers with regard to emergency management.

Objectives: This study was designed to examine the knowledge and attitudes of primary school teachers with regard to the emergency management of avulsed permanent incisors.

Design: Data were collected by self-administered questionnaire.

Setting: The study was conducted in primary schools lying within a 2-mile radius of the University Dental Hospital, Cardiff.

Dental care in acute lymphoblastic leukaemia: experiences of children and attitudes of parents.

Objectives: To profile the dental experiences of a group of children diagnosed as suffering from Acute Lymphoblastic Leukaemia (ALL) and to examine: 1) how parents of children diagnosed as suffering from ALL perceive the importance of dental care; 2) parental preferences with regard to the provision of dental care for children with ALL.

Setting: The study was conducted in one of the 22 United Kingdom Children's Cancer Study Group (UKCCSG) centres.

Sample And Methods: Data were collected by means of a structured interview, employing an administered questionnaire.

Consumer demand in the purchase and prescription of sugar-free medicines.

Objectives: To determine the current level of consumer demand in the purchase and prescription of sugar-free paediatric medicines.

Design: Data were collected by administered questionnaire.

Setting: The study was conducted in a Hospital Paediatric Dentistry Unit and a Community Dental Clinic, both within the Bro Taf area of south-east Wales.

Management of molar teeth with periodontal disease.

Over the years patients' attitudes towards maintaining a functional and aesthetic masticatory apparatus have improved, and their expectations of delivery of care by the dental professional have risen. With the advance of new techniques and materials, the periodontist can now offer an ever-expanding range of treatments in the management of molar teeth with periodontal disease. This paper considers such treatment in relation to the levels of disease present and within the overall context of adult restorative dental healthcare.

Relative susceptibility of deciduous and permanent dental hard tissues to erosion by a low pH fruit drink in vitro.

Objectives: The objectives of this study were two-fold: (1) to determine (by surfometry) loss of deciduous and permanent enamel and dentine following 15days' exposure to a single low pH orange drink; and (2) to determine (by surfometry) loss of deciduous and permanent enamel and dentine following exposure to the product 2 versus 4 times per day for 15days.

Methods: This in vitro study employed the validated methodology described by West and co-workers [Journal of Dentistry, 1998;26:329-335.]

Results: In all four tissues, erosion was progressive over time, though this pattern was more linear in enamel than in dentine.

Erosion of deciduous and permanent dental hard tissue in the oral environment.

Objectives: The objectives of this study were two-fold: (1) to determine (by surfometry) loss of deciduous and permanent enamel and dentine following consumption of a single low pH orange drink for 15days; and (2) to determine (by surfometry) loss of deciduous and permanent enamel and dentine following consumption of the product 2 versus 4 times per day for 15days.

Methods: Sixteen healthy volunteers participated in a single centre, single blind, 2-phase crossover study, conducted according to Good Clinical Practice, and employing the validated model described by West and co-workers (Journal of Dentistry 1998; 26:329-335).

Results: In all tissues, erosion was progressive over time, the pattern being more linear in enamel than in dentine.

The cost, effectiveness and cost effectiveness of removal and retention of asymptomatic, disease free third molars.

Purpose Of Investigation: The study was undertaken to identify the least costly, most effective and most cost-effective management strategy for asymptomatic, disease free mandibular third molars.

Methods And Patients: A decision tree model of the outcomes of mandibular third molar retention and removal was constructed. Probability data for possible outcomes were obtained from a comprehensive literature review and entered into the decision tree.

In at the deep end--an insight into scuba diving and related dental problems for the GDP.

Scuba diving is one of the fastest growing sports in the world. It is inevitable that the general dental practitioner (GDP) will have patients who participate in this sport and they should be aware of a number of problems that a diver can experience that are associated with the teeth and related structures. The aim of this article is to introduce the GDP to the dental problems associated with diving and make recommendations on dental care for scuba divers.
