    Notes: Abstract – This study describes a new fine-scaled system for classifying initial and advanced dental erosions. The system includes the use of study casts of the teeth in an epoxy resin with an accurate surface reproduction. The severity of erosion on each tooth surface is scored according to six grades of severity. In addition, the presence of a Class V restoration and dental erosion on the same surface increases the erosion score, as it is assumed that the need for restorative treatment can be caused by the erosion. A high inter-examiner agreement was found when the present scoring system was used by two examiners on the same sample. With this prerequisite it is proposed that an index value for facial, oral, incisal/occlusal and cervical surfaces is calculated as the mean value of scores for the respective surfaces. The index values represent the severity of tooth substance loss in various locations of the oral cavity and are furthermore suitable for data analysis. The system is thereby well-suited for determining etiologic factors and monitoring the progression of erosion over time.

    Notes: The association of oral candidiasis with the human immunodeficiency virus (HIV) infection has been known since the advent of the acquired immunodeficiency syndrom (AIDS) pandemic. Oral candidiasis is one of the earliest premonitory signs of HIV infection and its diagnosis may have grave prognositic implications for the eventual development of full blown AIDS. There is now an expanding body of data on novel clinical variants of this ‘old’disease, its epidemiology in HIV seropositive individuals and, advanes in its management, particulary with respect to the recently introduced bis-triazole antifungals. Current concepts pertaining to the epidemiology, clinical features, pathogenesis, laboratory diagnosis and management of oral candidiases in HIV infection are reviewed.

    Reactions of the oral mucosa related to silver amalgam: a review (1991)

    Notes: Lesions of the oral mucosa caused by amalgam restorations are rare. They may be due to Type IV contact hypersensitivity or toxic reactions to products generated by the restorations. Hypersensitivity reactions to amalgam seem to be related to mercury in almost all cases. The basis for requiring allergologic examination of patients suspected of contact hypersensitivity to amalgam is the presence of whitish or reddish, sometimes ulcerative oral mucosal lesions with a clear anatomic relation to amalgam fillings. The clinical features of lesions due to toxic reactions from amalgam restorations do not differ from those of lesions due to contact hypersensitivity, and the diagnosis is obtained by exclusion based on a negative patch test. Amalgam accidentally implanted in the oral mucosa results in amalgam tattoos which are flat lesions of bluish, blackish or slate grey color. Implanted amalgam does not produce an acute tissue response and need not be removed except for diagnostic reasons.

    Notes: Abstract: The aim of the present investigation was to assess the effect of four implant surface preparation methods used in the surgical treatment of experimental peri-implantitis with autogenous bone graft and expanded polytetrafluoroethylene (ePTFE) membrane. The methods were air-powder abrasive unit+citric acid, air-powder abrasive unit, gauze soaked in saline+citric acid, and gauze soaked alternately in chlorhexidine and saline. A total of 64 implants with a titanium plasma-sprayed (TPS) surface was placed in eight cynomolgus monkeys (Macaca fascicularis). After a 3-month period with plaque control, experimental peri-implantitis was induced. A bone loss of 4–6 mm was established after 9–17 months and plaque control was re-implemented. The peri-implantitis defects were surgically exposed, granulation tissue was removed, and each implant surface was prepared by one of the above-mentioned procedures. The defects were then filled with autogenous bone graft particles and covered by an ePTFE membrane. The animals were sacrificed after 6 months. Evaluation by clinical parameters, radiography including quantitative digital subtraction radiography, histology, and stereology did not reveal significant differences between the methods. Almost total bone regeneration and considerable re-osseointegration were obtained irrespective of the method applied. A mean bone-to-implant contact of 39–46% was observed within the defects. Therefore, the present study of implants with a TPS surface in cynomolgus monkeys indicates that the simplest method involving gauze soaked alternately in chlorhexidine and saline should be the preferred implant surface preparation method in the surgical treatment of peri-implantitis involving autogenous bone graft and ePTFE membrane.

    Notes: Abstract: The purpose of the present study was to evaluate the effect of autogenous bone graft particles and expanded polytetrafluoroethylene (ePTFE) membrane in the treatment of peri-implantitis with stereologic and histologic methods. Clinical and radiographic findings are reported elsewhere. Experimental peri-implantitis with a bone loss of 4–6 mm was established during 14–22 months around 64 implants with a titanium plasma-sprayed (TPS) surface in eight cynomolgus monkeys (Macaca fascicularis). The defects were treated with autogenous bone+membrane (B+M), autogenous bone (B), membrane (M), or a conventional flap procedure (control) (C). The animals were killed 6 months after surgery. Healthy peri-implant tissue was established irrespective of the applied treatment procedure. However, the amount of bone (autogenous bone graft particles and regenerated bone) and re-osseointegration were significantly higher in defects treated with B+M as compared with the three other treatment modalities. A mean bone-to-implant contact of 45% was estimated within defects treated with B+M. The corresponding values for the B, M, and C groups were 22, 21, and 14%. The present study therefore demonstrates that autogenous bone graft particles covered by an ePTFE membrane is a useful surgical treatment procedure of experimental peri-implantitis around implants with a TPS surface in cynomolgus monkeys. Obviously, there is a background for long-term evaluation in humans.

    Notes: Abstract: The purpose of the present study was to evaluate the effect of anorganic porous bovine-derived bone mineral (Bio-Oss®) and expanded polytetrafluoroethylene (ePTFE) membrane in the treatment of peri-implantitis. A total of 64 implants with a titanium plasma-sprayed (TPS) surface was inserted in eight cynomolgus monkeys (Macaca fascicularis). After a 3-month healing period with plaque control, experimental peri-implantitis characterized by a bone loss of 4–6 mm was induced during a period of 9–18 months. Surgical treatment involving Bio-Oss+membrane, Bio-Oss, membrane, or a conventional flap procedure (control) only was carried out. The animals were sacrificed six months after treatment. Evaluation by clinical parameters, radiography including quantitative digital subtraction radiography, histology, and stereology demonstrated healthy peri-implant tissue irrespective of the applied surgical procedure. However, the amount of re-osseointegration and the total amount of bone (Bio-Oss and regenerated bone) were significantly higher in defects treated with membrane-covered Bio-Oss as compared with the other three treatment procedures. A mean bone-to-implant contact of 36% was obtained within defects treated with membrane-covered Bio-Oss. The corresponding values for the three other treatment procedures were 13–23%. The Bio-Oss particles were in general highly integrated within the regenerated bone, but the particles in the occlusal part of the defects were entirely surrounded by connective tissue irrespective of membrane coverage. The present study demonstrates that surgical treatment involving Bio-Oss covered by an ePTFE membrane is a useful treatment modality of experimental peri-implantitis around implants with a TPS surface in cynomolgus monkeys. However, the treatment outcome is not as encouraging as seen with membrane-covered autogenous bone graft particles documented in a study with same experimental design.

    Periodontal diseases in HIV-infected patients (1994)

    Notes: Abstract Periodontal diseases may be the first clinical sign of human immunodeficiency virus (HIV)-infection. Since the immunosuppression and subsequent susceptibility may alter the responses of the oral tissues as well as the microflora, both periodontal treatment and result of therapy may be modified. The periodontal diseases in HIV-seropositive patients include common as well as less conventional forms of gingivitis and periodontitis, and bacteria, mycotic and viral infections are seen. Neoplasias may also involve the periodontium; most common are Kaposi's sarcoma and non-Hodgkin's lymphoma. Recent studies of unselected groups of patients indicate that periodontal health in at least some groups of HIV-seropositive patients is better than previously reported.

    Notes: Abstract: The purpose of the study was to examine the effect of autogenous bone graft particles and expanded polytetrafluoroethylene (ePTFE) membrane in the treatment of peri-implantitis. The treatment outcome was evaluated by clinical and radiographic methods including quantitative digital subtraction radiography. A total of 64 implants with a titanium plasma-sprayed (TPS) surface was inserted in eight cynomolgus monkeys (Macaca fascicularis). After a 3-month healing period with plaque control, experimental peri-implantitis characterized by a bone loss of 4–6 mm was established during 14–22 months. Plaque control was then re-implemented and surgical treatment involving autogenous bone+membrane (B+M), autogenous bone (B), membrane (M), or a conventional flap procedure alone (control) (C) was performed. The animals were killed 6 months after treatment. Healthy peri-implant tissue was established irrespective of the applied surgical procedure. A mean bone gain of 4.7 mm was identified around implants treated with B+M, while, respectively, 4.0, 3.0, and 1.9 mm were recorded within the B, M, and C groups. Quantitative digital subtraction radiography confirmed considerable bone gain within defects treated with autogenous bone with or without membrane coverage. The bone gain, especially for defects treated with B+M, seemed to be almost to the level before development of peri-implantitis. By contrast, 38 and 25% of the defect was on average characterized by bone gain when, respectively, M or C was used alone. The present study of implants with a TPS surface in cynomolgus monkeys thus demonstrates considerable bone regeneration after treatment of experimental peri-implantitis with autogenous bone graft particles with or without ePTFE membrane coverage. Further stereologic and histologic evaluation of the treatment outcome is necessary before final conclusions about the effect of autogenous bone graft and ePTFE membrane can be made.
