OBJECTIVES It has been suggested that periodontal inflammation may result in an altered immune response. The peripheral immune capacity in periodontitis patients can be investigated using lipopolysaccharide (LPS)-stimulated whole blood cell cultures (WBCC), known to reflect the behavior of monocytes in particular. A previous study in our laboratory revealed(More)
UNLABELLED BACKGROUND AND DESCRIPTION OF CASE: The etiology and pathogenesis of generalized cervical root resorptions is not well understood. In the present report, a case of severe cervical root resorption involving 24 anterior and posterior teeth is presented. The lesions developed within a period of 2 years after the patient had changed to an(More)
AIM This study was designed to test whether the approximal efficacy of a powered toothbrush (Braun Oral-B 3D Plaque Remover) can be improved when a pointed-shaped brush head (PBH) specifically designed for these approximal areas is used as compared with the standard cup-shaped brush head (CBH). MATERIAL AND METHODS Forty non-dental students were included.(More)
AIM The purpose of the present study was to compare the ability of the Braun Oral-B 3D Excel power toothbrush (BPT), the Sonicare power toothbrush (SPT) and the Philips Sensiflex 2000 (HX 2550) power toothbrush (PPT) to control plaque and reduce experimentally induced gingivitis. MATERIALS AND METHODS Two experiments were carried out in two different(More)
OBJECTIVES Does a high brushing force induce more gingival abrasion than a low (regular) brushing force? Furthermore, what is the effect of a low or high force on the efficacy? METHODS Thirty-five non-dental students were selected. All received an appointment prior to which they abstained from oral hygiene for at least 48 h. At baseline the teeth and(More)
OBJECTIVES This study was designed to evaluate two factors possibly influencing incidence of gingival abrasion during toothbrushing: (1) the abrasiveness of a dentifrice and (2) the possible influence of feedback of oral sensory perception. MATERIAL AND METHODS For this purpose, two separate, single blind, randomized clinical experiments were performed.(More)
OBJECTIVES This study was designed to test the efficacy in plaque removal and the potential for gingival abrasion of 3 electric toothbrushes. The established Braun Oral-B 'Ultra' plaque remover (D9), the Philips/Jordan HP 735, and the newly designed Braun Oral-B 3D Plaque Remover (3D). MATERIAL AND METHODS This study was designed as a split-mouth, single(More)
OBJECTIVES The objective of this study was to compare the effect of an oscillating/pulsating power toothbrush (Oral-B ProfessionalCare 7000; PC 7000) and a high-frequency power toothbrush (Philips Sonicare Elite; SE) on the reversal of experimental gingivitis. METHODS The study had a randomised, examiner-blind, split-mouth design. After dental(More)
OBJECTIVES To compare a tapered filament toothbrush (TFTB) to a control toothbrush (ADA) in their potential to cause gingival abrasion and improve the gingival condition following a period of experimental gingivitis. METHODS Thirty-two subjects refrained from brushing mandibular teeth for 21 days. During a subsequent 4-week treatment phase, the left or(More)
OBJECTIVES This parallel examiner blind study was designed to compare the results of professional brushing with an electric toothbrush (ETB, Braun Oral-B 3D Excel) to a professional polish session. MATERIAL AND METHODS For this study, 90 non-dental students were selected. All received a single oral prophylaxis where plaque and calculus were removed and(More)
