    Abstract Background: The aim of the present study was to assess thickness of all parts of the masticatory mucosa by using an ultrasonic measuring device.
    Methods: A total of 40 periodontally healthy subjects, 19 to 30 years old, took part. Thickness of masticatory mucosa was measured at a maximum of 149 sites in each proband.
    Results: Female volunteers had significantly thinner mean masticatory mucosa than males (p<0.01). Mean thickness of facial gingiva ranged between 0.7 mm at canines in the maxilla and central incisors in the mandible and 2.3 mm at 3rd molars in the mandible. In the mandible, thickness of lingual gingiva ranged between 0.9 mm at lateral incisors and 2.3 mm at 3rd molars. Interdental gingiva ranged between 1.0 mm 2.1 mm. With 3 mm or more, on average, palatal masticatory mucosa was thickest in the 3rd molar region and at 2nd premolars at more central locations. 2 regions with comparatively thin palatal mucosa of about 2 mm were identified, namely (i) at central and lateral incisors and (ii) at the prominence of the palatal roots of 1st and 2nd molars. The thickest tissue with more than 4 mm, on average, was observed in the tuberosity and retromolar regions.
    Conclusions: Considerable intra- as well as interindividual variation of thickness of masticatory mucosa could be observed. According to differences in thickness of facial and interdental gingiva, it appears that lining is also an important function of the gingiva in reducing and smoothing the pronounced convexities of the dentoalveolar, i.e., skeletal, complex.

    Abstract The objectives of the present study were (I) to determine the validity and reliability of measuring gingival thickness (GTH) with a recently developed, commercially available ultrasonic device; (II) to measure GTH in relation to tooth type and age of proband; (III) to correlate GTH with varying forms of premolars, canines and incisors. Ultrasonic measurements were performed in 200 periodontally healthy, male probands representing 3 different age groups (20-25, 40-45, 55-60 years). In the maxilla, mean GTH varied between 0.9 mm (canines, 1st molars) and 1.3 mm (2nd molars). In the mandible respective mean values ranged between 0.8 mm (canines) and 1.5 mm (2nd molars). No differences in means and standard deviations (0.36-0.39 mm) were observed in different age groups. In order to correlate GTH with other clinical parameters and form of tooth, in 42 probands of the youngest age group, presenting with no attrition or abrasion, no artificial crown restorations and (following prophylaxis) no overt gingivitis and no periodontal probing depth in excess of 3 mm, detailed clinical measurements and stone model cast analyses were performed. By stepwise multiple linear regression analysis, 24% (p < 0.0001) of the variation of GTH was explained by probing depth, recession, width of gingiva and tooth type. The ratio of the width of the crown to its length was not included into the model. When performing analysis of covariance with the subject as factor, the model was improved, now explaining 41% of the variation of GTH. In this model, the influence of periodontal probing depth was decreased, and recession was not included. It was concluded that there are individual differences in GTH (i.e., different biotypes). However, thickness mainly depends on tooth type and is correlated with width of gingiva. There appears to be no association with shape and form of the tooth. Validity and reliability of measuring GTH with the ultrasonic device was found to be excellent.

  3. Article: Management of furcation-involved teeth. A retrospective analysis.

    Müller, H P / Eger, T / Lange, D E

    Abstract In the present study, data from more than 550 periodontally diseased patients with more than 1100 furcation invasions were retrospectively analysed. There were apparent differences in the distribution of different furcation degrees in patient populations treated by 2 differently experienced operators. However, treatment modality patterns were rather similar. Scaling during periodontal flap surgery was the most often performed treatment procedure in degree I (97-98%) and II (75-83%) involvements. About 44% of degree III involved teeth were extracted. In order to determine the influence of degree of furcation involvement, tooth type and operator variability on treatment modality, logistic regression analysis was applied. Degree of furcation involvement was an important indicator variable in all models. Scaling as a sole measure was mainly performed in relation to degree I of furcation involvement. With every increase in degree, the odds of scaling decreased by factor 12.7. The odds of root resection was upper 1st molars 46 x higher than in wisdom teeth or lower 2nd molars with the same degree of involvement, but only 3.3 x higher than in lower 1st molars. Tunnel preparation as well as regenerative procedures were mainly confirmed to lower molars. Operator variability was only introduced as a covariate in the extraction model. hence, despite of different operator skill and severity of periodontal disease in treated populations, decision for one or the other treatment modality seems to depend essentially on degree of furcation involvement as well as tooth type.

    Abstract The rate of rise of the alveolar:inspired halothane concentration (F delta/F1) ratio was measured in dogs breathing spontaneously. These rates were measured at inspired concentrations of 0.3, 1.5, and 4 percent. Initially, FON (FA/F1) ratio was measured in dogs breathing spontaneously. These rates were measured at inspired concentrations of 0.3, 1.5, and 4 percent. Initially FA/F1 rose at similar rates for all 3 concentrations, but a 4 percent, the plateau attained was lower as a result of respiratory depression. In a 2nd group of dogs, FA/FI was measured for inspired concentrations of 0.3, 1.5, 4, and 6 percent during controlled ventilation. FA/FI rose at similar rates at the lower 2 concentrations but at progressively more rapid rates at inspired concentrations of 4 and 6 percent, presumably as a result of circulatory depression.

    Title translation Effect of plasmapheresis treatment on immunoglobulin and immune complex levels in patients following kidney transplantation.
    Abstract Five patients who received cadaver kidneys between May 1982 and January 1983 in the Kidney Transplant Centre in Berlin were subjected to two plasmapheresis (= pph.) treatments in addition to basic immunosuppression with Prednisolone and Azathioprine. The decision to use pph. was due to the presence of donor-specific, complement-dependent lymphocytotoxic antibodies (51Cr release test) in the recipient's serum taken immediately before transplantation. The 1st pph. was carried out on the 1st or 2nd day after operation and the 2nd pph. between the 2nd and 4th day. The quantity of plasma exchanged was between 1.6 and 3.1 1 per pph. Four of the five transplants commenced functioning after 12 to 47 days, and one transplant had to be removed. Frequent measurement of the immunoglobulin and immune-complex levels in the serum revealed drastic reduction due to pph. The concentration of immunoglobulin (G, A, M) was reduced by 42-55% after the 1st pph. and by 20-35% after the 2nd. Whereas the IgM level was normalized after a few days, the levels of IgG and IgA only rose again 2-4 weeks later. The immunodeficiency induced by means of pph. and immunosuppression is accompanied by an increased risk of infection. It is therefore considered important that an adequate anti-infectious treatment including i. v. human gammaglobulin be administered parallel to pph. The final evaluation of the efficacy of pph. in protecting transplants will depend on further studies.
