Clinical experiences of undergraduate dental students in pediatric dentistry at Cork University Dental School and Hospital, Ireland.

The objectives of this study were to evaluate the number and range of clinical procedures completed by undergraduate dental students in pediatric dentistry in Cork University Dental School and Hospital, Ireland, and to compare the number of procedures undertaken with the subsequent examination scores. The work comprised a retrospective audit of clinical logbooks for all of the undergraduate dental students in one cohort through their fourth and fifth clinical years between 2004 and 2006. Thirty-four quantitative logbooks were audited.

Occlusal accommodation and mouthguards for prevention of orofacial trauma.

Purpose: The aim of this study was to investigate the effect of two types of occlusal accommodation on the arch separation in centric and eccentric arch positions and to assess the opposing tooth contacts in professionally made, thermoformed sports mouthguards.

Materials And Methods: Maxillary and mandibular alginate impressions, a wax interocclusal record of centric occlusion together with maxillary/condylar face-bow registrations, were recorded clinically for 10 undergraduate dental students who are sports activist volunteers of the School of Medicine and Dentistry, Queen's University Belfast. Two ethylene vinyl acetate thermoformed maxillary mouthguards were made for each player (N = 20) using a standardised procedure.

Factors affecting the timing of pulp extirpation in a sample of 66 replanted avulsed teeth in children and adolescents.

The management of 66 replanted avulsed permanent teeth in 46 patients over a 4-year period was studied. Treatment was compared with the recommendations in published guidelines for the management of avulsed permanent teeth. For total extra-alveolar times longer than 45 min, the pulps were extirpated in 96% of teeth.

Post thermoforming dimensional changes of ethylene vinyl acetate used in custom-made mouthguards for trauma prevention--a pilot study.

It is important that mouthguards have an adequate thickness of material if they are to be effective in the prevention of trauma. The aim of this study was to quantify dimensional changes that occur on thermoforming ethylene vinyl acetate (EVA) sheets used in the construction of mouthguards. Fourteen batches of 3 mm thick sheet EVA were thermoformed over dental models under a number of common processing conditions including, model height, inclination, shape and model temperature, model position on thermoforming platform, plasticizing time and evacuation method.

The hierarchical cluster analysis of oral health attitudes and behaviour using the Hiroshima University--Dental Behavioural Inventory (HU-DBI) among final year dental students in 17 countries.

Objective: To explore and describe international oral health attitudes/ behaviours among final year dental students.

Methods: Validated translated versions of the Hiroshima University-Dental Behavioural Inventory (HU-DBI) questionnaire were administered to 1,096 final-year dental students in 17 countries. Hierarchical cluster analysis was conducted within the data to detect patterns and groupings.

External inflammatory and replacement resorption of luxated, and avulsed replanted permanent incisors: a review and case presentation.

External inflammatory resorption and replacement resorption are complicating factors that may result from traumatic dental injuries when the tooth is luxated or avulsed and replanted. Resorption may, ultimately, result in loss of the tooth. However, with appropriate treatment, the prognosis for these teeth is greatly improved, with the possibility of preventing or arresting resorption.
