    Notes: Abstract. Several publications have reported an increased susceptibility for root caries after periodontal therapy. It has been suggested that newly exposed roots were less resistant to cariogenic species. This study examined the hypothesis that the increased susceptibility could also be related to an intra-oral microbial shift during the initial phase of the periodontal therapy from a perio-pathogenic to a more cariogenic flora. 10 patients with severe periodontitis were followed for 8 months after thorough scaling and root planing in combination with optimal plaque control. At baseline and after 4 and 8 months, samples were taken from the saliva, the tongue dorsum and the supragingival interdental spaces. These samples were cultured both aerobically and anaerobically in order to determine the total number of colony forming units (CFU) per sample as well as the number of CFU of Streptococcus mutans and Lactobacillus species. Oral hygiene parameters were recorded at the same visits. Finally, at baseline and at the 8 months follow-up, changes in caries activity and periodontal health were registered. Although the total number of aerobic and anaerobic CFU in samples from the tongue and the saliva remained nearly constant over the entire observation period (variations within 0.5 log), significant (p≤0.05) increases in the number of S. mutans could be detected, especially at month 8. The significant decrease in the total number of anaerobic CFU in samples from the teeth was not associated with a reduction in the number of S. mutans, so that also for this niche the relative proportion of the latter increased. The number of lactobacilli species for the different niches showed only negligible changes (within 0.5 log values), except for samples from the teeth for which a small (1 log), but statistically significant (p〈0.01), reduction could be detected. The periodontal conditions improved for all patients, but the caries activity could not be arrested. These findings seem to indicate that the increased caries susceptibility after periodontal therapy might partially be explained by a significant increase in the number of S. mutans due to ecological changes within the oral cavity. The clinical consequence of this observation would be to advocate a more strict caries preventive program during initial periodontal therapy.

    Notes: Abstract The aim of this study was to determine the need for oral health care in young Belgian children in the municipality of Leuven, Belgium. The sample consisted of 750 boys and girls (3 years=200, 4 years=200 and 5 years=350). Clinical examination was carried out by one examiner and duplicate recordings were made on 10% of the sample. The clinical examination included recording of: (1) plaque index; (2) gingival index; (3) caries index; and (4) fluorosis index. Plaque and gingival indices were recorded at six sites of smooth surfaces on selected teeth. Occlusal plaque was also registered. Before the clinical examination for caries and fluorosis, the children had their teeth professionally cleaned with toothbrushes and dental floss and dried by means of gauze bandages. In all age groups, the percentage of plaque-free sites was of the order of 60% and sound gingiva was identified at 83% of the recorded sites. The percentages of caries-free children were 69% (3 years), 57% (4 years) and 52% (5 years). The mean deft scores (standard error) were 1.37 (±0.21), 1.76 (±0.21) and 2.03 (±0.17). The corresponding mean defs scores were 2.04 (±0.44), 2.46 (±0.35) and 3.75 (±0.42). Non-cavitated active lesions, included in the defs scores, represented about 50% of all caries lesions. Early signs of dental fluorosis were identified in 19% (3 years), 17% (4 years) and 9% (5 years) of children. The need for oral health care in the population studied is mainly related to non-operative treatment procedures aimed at controlling the progression of disease.

    Notes: Abstract The aim of the present study was to describe in detail the distribution of caries lesions among tooth types and surfaces in the primary dentition of young children with different levels of disease. A total of 125 children (between 2 and 6 years old) attending the pediatric dental clinic of the University Hospital of Leuven was allocated to three groups based on their caries experience: dmft=1–5 formed the low caries experience group (LC, n=27), dmft=6–9 the moderate caries experience group (MC, n=61) and those with dmft〉=10 the high caries experience group (HC, n=37). Caries experience (at patient level, tooth and tooth surface level) and oral hygiene were evaluated. Oral health habits were recorded using a questionnaire (completed by parents). Caries lesions were not evenly distributed among different tooth types. Teeth most frequently affected were lower (first and second) primary molars. Primary incisors were rarely found to be carious. The distribution of the lesions followed a comparable pattern, irrespective of the disease level of the child. Decay on primary canines and buccal/lingual surfaces of primary molars was strongly indicative of a high caries experience. There was a clear link with reported oral hygiene habits and the use of a pacifier and baby bottle with sugared content.

    Notes: A multi-stage screening and identification scheme for the diagnosis of inborn errors in amino acid, fatty acid, carbohydrate and intermediary metabolism is described. The method is based on a computerized analysis of data obtained with dual-column gas chromatography/FID (GC/FID) and gas chromatography/mass spectrometry (GC/MS) profiling of urinary organic acids. It involves: (1) isolation of the compounds by solvent or solid-phase extraction; (2) conversion into trimethylsilyl (TMS) or TMS-oxime derivatives; (3) GC/FID analysis on SE-52 and OV-1701 capillary columns; (4) tentative identification by comparing the methylene unit (MU) values on both columns with a user-built library of reference compounds; (5) quantitative evaluation of the excretion profile; and (6) analysis by GC/MS of samples with an abnormal profile using an automated peak identification programme.
