Congenital erythropoietic porphyria--oral manifestations and dental treatment in childhood: a case report.

Congenital erythropoietic porphyria is a rare condition resulting from an inborn error in prophyrin metabolism. This deficiency leads to hemolytic anemia, photosensitivity, blistering of the skin, and deposition of red-brown pigments in the bones and teeth. The literature regarding the dental aspects of this disorder is briefly reviewed and the preventive, restorative, and esthetic dental management of a 4-year-old child with congenital erythropoietic porphyria is described.

The effect of different concentrations of citrate in drinks on plaque pH.

The effect of 0.1, 0.2 and 0.4% citrate in 10% sucrose solutions on the plaque pH in vivo was tested in 20 volunteers using the plaque harvesting technique. Results showed that the pH response for the three test solutions with citrate was significantly less compared with that for 10% sucrose (positive control) alone (p < 0.05). Mean areas under the pH curve were: sorbitol (negative control) 0.02, citrate 0.2% 5.30, citrate 0.4% 6.24, citrate 0.1% 6.94 and 10% 12.69. The cariogenic potential index of all the citrate test drinks was almost half compared with a 10% sucrose solution (p < 0.05). It was concluded that the addition of relatively low levels of citrate in a sucrose solution reduces the acidogenic response in the plaque.

Dental health and salivary Streptococcus mutans levels in a group of children with heart defects.

One-hundred children aged 2-16 years who were attending the Outpatients Department of the Yorkshire Regional Cardiac Centre were examined for dental caries, gingivitis, plaque and calculus. A control group of 100 children was also examined. A saliva sample was taken from each child in the study group to assess the level of Streptococcus mutans colonization. Comparing study and control groups, dental caries experience (dmft) was significantly higher only in the primary teeth of 5-9-year-old children in the study group, and there were no significant differences in gingivitis, plaque or calculus. The S. mutans count was found to be positively correlated to the number of decayed teeth in the study group.

The effectiveness of the yellow card warning system for paediatric cardiology patients.

Questionnaires were completed by the parents of 100 children with cardiac problems attending the regional paediatric cardiology clinic in Yorkshire. The parents' possession and knowledge regarding the use of a yellow card (warning parents and dentists of the need for antibiotic cover before certain dental treatment) was assessed. Only 57 per cent of parents reported that they had received a yellow card.

Restoration of decayed primary incisors using strip crowns.

Caries of the primary incisors is a common problem that can be arrested if recognized early enough. However, the arrested decay is unsightly. Celluloid 'strip' crown forms, used with composite resin, now allow the restoration of even the most badly decayed primary incisors. The authors describe this quick and efficient technique.

Acid anion profiles in dental plaque following consumption of cereal-based foods and fruits.

The aim of this study was to investigate the acid anions produced in plaque after chewing various cereal-based foods and fruits for one minute. Test foods were oranges, apples, bananas, Cornflakes, Branflakes, Weetabix, Alpen, white bread, wholemeal bread, rice and spaghetti, plus positive and negative controls of 10% sucrose and 10% sorbitol. 4 males and 3 females, aged 22-37 years, participated in the study .7 min from the start of chewing, 48-h plaque was collected from all accessible smooth surfaces, with no attempt to collect interproximal plaque, and centrifuged. Plaque fluid was withdrawn and analyzed by isotachophoresis for formate, succinate, lactate, acetate and propionate. At rest, acetate was the major anion present in plaque fluid, whereas following carbohydrate consumption, highest levels of lactate were detected followed by acetate. The amount of lactate only, detected in plaque fluid, was significantly correlated to the carbohydrate present in the food. It was concluded that important information regarding the acidogenicity of test foods is gained by studying the acid anion profile of plaque fluid.

The dental status of asthmatic British school children.

PURPOSE: This study was performed to determine the prevalence of dental disease in British school children with asthma. METHODS: A convenience sample of 100 asthmatic children (aged 4-16 years) was examined for dental caries, periodontal condition, and tooth surface loss. School children, equated for age, sex, race, and socioeconomic status were chosen for comparison. Children were divided into two age ranges; 4-10 and 11-16 years. A significant difference was found in DMFT (0.96 vs. 0.31) and DMFS (1.37 vs. 0.37) between the 4-10-year-old asthmatic children compared with healthy control children. RESULTS: In the 11-16-year age range, the asthmatic children had a DMFT and DMFS of 2.48 and 3.39 compared with the control children who had a DMFT and DMFS of 1.11 and 1.97 respectively. Asthmatic children had significantly more plaque, gingivitis, and calculus compared with the control group. There was a significant difference in the severity and number of teeth affected by tooth surface loss affecting labial surfaces of the anterior teeth and occlusal surfaces of the posterior teeth of asthmatic children. CONCLUSIONS: It was concluded that asthmatic children have more decay affecting their permanent teeth, poorer periodontal status, and more tooth surface loss than healthy controls.
