Dysmorphophobia is a syndrome in which a person of normal appearance becomes obsessed with an aspect of their appearance which they feel is noticeably defective, and for which they constantly seek treatment. This case report describes the successful management of a young woman with dysmorphophobia using a multidisciplinary approach.
This study examined the effects of temperature and humidity variations on the bond strength of sand blasted Ni-Cr-Mo alloy (Talladium) cylinders cemented to etched bovine enamel using composite resin (Panavia Ex). Bonding was carried out in a humidity chamber under varying combinations of temperature (24 degrees C and 37 degrees C), and relative humidity (32% and 85%). After storage in water at 37 degrees C for 24 hours all specimens were shear tested to failure. The results showed that bond failure was consistently cohesive with resin shear strength at 37 degrees C being significantly reduced by high humidity. At 24 degrees C, resin shear strength was not significantly affected by humidity variations.
The aim of this prospective study was to audit casual attendance at the Conservation clinic of the School of Clinical Dentistry, Belfast. Details of 500 consecutive casual patient attendances were collected over a four month period. There were 253 male and 247 female patients with a mean age of 43.4 years. Fifty-eight percent of patients lived within five miles of the clinic with 16% travelling more than 15 miles. Sixty-five per cent of patients were self-referred, 27% were referred from within the School and 3% were referred from their General Dental Practitioner. Pulpal or endodontic problems were diagnosed in 42% of cases, 25% presented with loss of a crown or bridge and 14% complained of a pain-free loss of the filling. Half the patients were given a further appointment to attend the Conservation clinic while only 33% were directed to the General Dental Services for further care. It was concluded that the majority of casual attendees to the Conservation clinic were local residents who referred themselves for treatment. A minority of patients were currently under treatment at the School of Clinical Dentistry but over 65% remained their immediate responsibility. Recommendations for improvements in the current service were also made.
An important factor affecting plaque retention is the presence of amalgam restorations which are poorly contoured at the gingival margin. The aim of the study was to investigate the occurrence and effects of overhanging amalgam restorations in young adults. One hundred patients, aged 20-29 years, referred to the Periodontal Department, School of Dentistry, Belfast were investigated. Bitewing radiographs were used to examine the restorative status of the approximal surfaces of premolar and permanent molar teeth, excluding third molars. Fifty-seven per cent of the patients investigated had at least one amalgam overhang and 27 per cent had three or more overhangs visible on the radiographs. One hundred and seventy-eight (25 per cent) of the restored approximal surfaces had detectable amalgam overhangs. The mean bone level-amelocemental junction (ACJ) distance related to the approximal surfaces with overhangs was 1.77 (s.d. 1.0) mm and 37 (32 per cent) of these surfaces had bone levels which were greater than 2 mm from the ACJ. The mean bone level-ACJ distance for the other approximal surfaces of the teeth with overhangs was 1.63 (s.d. 1.2) mm. The mean bone level-ACJ distance for matching control surfaces on contralateral teeth was 1.86 (s.d. 1.2) mm. It was concluded that overhanging amalgam restorations were common in the restorations of young adults (20-29 years old) referred for periodontal treatment but were not associated with increased levels of bone destruction.
