SamNor:  I Norge har vi rikelig tilgang på vann, men forurensing truer kvalite
         ten på drikkevannet. Grunnvann er relativt godt beskyttet mot foruren
         sing. Det mindre enn 15% av befolkningen som bruker grunnvann i husho
         ldningen, men prosenten øker raskt. Grunnvann er (oftest) rent og sma
         ker godt. Grunnvann i fjell kan inneholde til dels betydelige mengder
          med oppløste grunnstoffer og kjemiske forbindelse. Noen av disse sto
         ffene har helsemessig betydning. Vi rapporterer her analyse av 150 va
         nnprøver fra grunnvannskilder i fjell i Hordaland og Vestfold. I alt
         64 grunnstoffer ble undersøkt ved bruk av avansert utstyr (JCP-MS o.l
         .) Innholdet av grunnstoffer var - i de fleste vannprøvene - i harmon
         i med gjeldende regler for godt drikkevann, men for noen stoffer ble
         det funnet verdier som overskrider normene for veiledende eller størs
         te tillatte konsentrasjon. Dette gjaldt Al, As, Ba, Ca, Cd, F, Fe, Hg
         , K, Mg, Mn, Na, P, Pb og Rn og Zn. For et flertall av de undersøkte
         stoffene eksisterer det ikke noe norsk regelverk med angivelse av mak
         simumsverdier i drikkevann; til tross for at (enkelte av) stoffene ka
         n ha klar helsemessig relevans. Dette gjelder bl.a. Be, Mo, Th og U.
         Undersøkelsen understreker behovet for en systematisk analyse av nors
         ke grunnvannskilder, og etterlyser klare regler for kontrollrutiner o
         g godkjenning av vannkvaliteten i små, private vannverk og brønner.

SamNor:  The middle layer consisted of arterioles (Ø=25±6m) from the anteri
         or superior alveolar artery that ran parallel to the long axis of the
          incisor mainly centrally, branching off smaller arterioles to the ca
         pillary network. The outer layer was formed of flattened sinusoid ves
         sels of large caliber (Ø=105±26m) which anastomosed with the capil
         lary network, arterioles, venules as well as with the vascular bed co
         mponents of the periodontal ligament proper. Blood flow was from the
         anterior superior alveolar artery branches through the arterioles int
         o the capillary network. It was then drained posterolaterally along t
         he cemento-enamel junction via short venules which emptied into the s
         inusoid vessels, finally to flow through Volkman’s canals into the al
         veolar bone. The sinusoid vessels seemed to act as a blood reservoir
         with possible cushioning blood shifting and eruptive functions. The m
         icrovasculature of the rat incisor enamel organ has an exceptionally
         high level of structural organization in which blood flows from centr
         ally located axial feeding arterioles through a network of capillarie
         s to be drained by venules and sinusoid vessels into the alveolar bon
         e.
SamEng:  Knowledge of the microvascular bed of the rodent incisor enamel organ
          is scarce, imprecise, conflicting and lacks quantitative data. This
         study was initiated to assess the microvascular architecture of the e
         namel organ of the rat maxillary incisor by the use of vascular corro
         sion casts and scanning electron microscopy (SEM). Thirteen young mal
         e Wistar rats were sacrificed. Vessel diameters were measured in m
         on standardized SEM micrographs. Means and standard deviations were c
         alculated for each vessel category. Several vascular layers were iden
         tified in the labial periodontal space. The inner layer in direct rel
         ation to the enamel organ consisted of a capillary network (Ø=12±2
         m)which had a honey comb-like pattern with extensive anastomosis prox
         imally. The pattern changed gradually in the coronal direction into a
          bundle-like network centrally and a ladder-like system laterally. Ne
         ar the cemento-enamel junction, the capillary bed was drained by shor
         t venules (Ø=24±5m).

SamEng:  The purpose of this study was to assess the caries prevalence of chil
         dren living in areas with either 0.25 or 2.5 ppm fluoride in the drin
         king water, and to relate caries experience to severity of dental flu
         orosis. The children, aged 6-16 years (mean 11.3 years) were lifelong
          residents of their rural villages. The severity of dental fluorosis
         in the maxillary central incisors, assessed by Deans index, was 1.4 ±
          0.9 (n=59) and 2.3 ± 0.9 (n=65) in the 0.25 and 2.5 ppm areas, respe
         ctively. There was no significant difference in DMFT between children
          from the two areas (2.6 ± 2.3, n=59 versus 2.1 ± 2.3, n=65). In the
         low-fluoride areas 75% of the children had decayed permanent teeth co
         mpared to 66% in the high-fluoride area. In the primary teeth, howeve
         r, both the caries prevalence and the dmft were significantly lower i
         n the 2-5 ppm area than in the low-fluoride area. Stepwise, multiple,
          linear regression analyses, including all children, showed a signifi
         cant effect of age on DMFT (30% of the variance explained), but no ex
         planatory effect of fluoride in drinking water, severity of dental fl
         uorosis, or gender. Regression analyses based on children in the 2.5
         ppm area alone, showed significantly higher DMFT by increased severit
         y of dental fluorosis. In children with a mixed dentition (n=66), the
         re was no association between caries in the primary and permanent tee
         th.

          a mixed dentition (n = 66), there was no association between caries
         in the primary and permanent teeth.

SamNor:  This study evaluated site-by-site the relations between subgingival m
         icrobial colonization and gingival tissue reactions. Experimental, de
         ep periodontal defects were established at buccal surfaces of mandibu
         lar and maxillary canine teeth in 5 beagle dogs. The root surfaces we
         re instrumented by a flame-shaped, fine-grained, rotating diamond poi
         nt, or by a sharpcuret. Following a 10-day postsurgical healing perio
         d, the dogs were fed a plaque-inducing diet for 70 days. The animals
         were then sacrificed and tissue blocks of the experimental sites incl
         uding teeth and periodontal tissues were secured. The buccal gingiva
         was removed and processed for histomorphometric analysis while the te
         eth were prepared for scanning electron microscopic evaluation of the
          extent of subgingival microbial colonization. The results revealed t
         hat inflammatory cell density in the junctional epithelium and the co
         nnective tissue were positively correlated to subgingival microbial c
         olonization (P < 0.01). Furthermore, the degree of significanc
         e decreased with increasing distance from the plaque. The p resent st
         udy demonstrates that a close relation may exist between the extent o
         f subgingival microbial colonization and inflammatory gingival tissue
          reactions.
