Impact of periodontal disease and periodontal therapy on oral health-related quality of life.

Objective: To determine the impact of periodontal disease and periodontal therapy on oral health-related quality of life using the German version of the Oral Health Impact Profile, taking into account the possible effects of age, gender and socioeconomic factors.

Methods: This is a study of 93 patients of both sexes aged 27-74 years. The sample included 82 patients with a diagnosis of periodontal diseases, 11 patients without periodontitis (control group).

A randomized clinical multicentre trial comparing enamel matrix derivative and membrane treatment of buccal class II furcation involvement in mandibular molars. Part III: patient factors and treatment outcome.

Objective: Evaluation of effects of patient factors on the outcome of regenerative treatment of buccal mandibular class II furcation defects.

Material And Methods: Fifty-one patients were recruited. In the intention-to-treat population 21 patients were allocated into the sequence left treatment with enamel matrix protein derivative (EMD) and right guided tissue regeneration (GTR) and 27 in the sequence left GTR and right EMD.

Goals for oral health in Germany 2020.

Constant themes in the worldwide debate on public health policy are, on the one hand, the medical aspects, including those of social medicine, together with healthcare provision, and, on the other, considerations of health economics. Although it is essential for healthcare resources to be allocated appropriately, medical criteria should take precedence. One branch of research in the field of healthcare provision, the definition of health goals, is assuming increasing importance in this connection, in dentistry as in other spheres.

A randomized clinical trial comparing enamel matrix derivative and membrane treatment of buccal class II furcation involvement in mandibular molars. Part II: secondary outcomes.

Background: This multicenter, randomized trial compared enamel matrix derivative (EMD) with barrier membranes for the treatment of Class II mandibular furcations with regard to secondary outcomes. The influence of furcation morphology on the effectiveness of either treatment was also evaluated.

Methods: Forty-eight patients (age range 28 to 73 years; 22 females, 26 males) with buccal Class II furcation involvements in both contralateral lower first or second molars were included.

A randomized clinical trial comparing enamel matrix derivative and membrane treatment of buccal Class II furcation involvement in mandibular molars. Part I: Study design and results for primary outcomes.

Background: The objective of this multicenter, randomized trial was to compare enamel matrix derivative (EMD; test) with barrier membranes (control) for the treatment of mandibular buccal Class II furcation defects.

Methods: Forty-five patients with 90 comparable defects on contralateral molars were included. Defects were randomly assigned to EMD or bioabsorbable barrier membrane; the contralateral defect received the alternative treatment.

Periodontal treatment with an Er:YAG laser or scaling and root planing. A 2-year follow-up split-mouth study.

Background: Non-surgical periodontal treatment with an Er:YAG laser has been shown to result in significant clinical attachment level gain; however, clinical results have not been established on a long-term basis following Er:YAG laser treatment. Therefore, the aim of the present study was to present the 2-year results following non-surgical periodontal treatment with an Er:YAG laser or scaling and root planing.

Methods: Twenty patients with moderate to advanced periodontal destruction were treated under local anesthesia, and the quadrants were randomly allocated in a split-mouth design to either 1) Er:YAG laser (ERL) using an energy level of 160 mJ/pulse and 10 Hz, or 2) scaling and root planing (SRP) using hand instruments.

Clinical evaluation of an Er:YAG laser combined with scaling and root planing for non-surgical periodontal treatment. A controlled, prospective clinical study.

Objectives: The purpose of the present controlled clinical trial was to compare the treatment of advanced periodontal disease with a combination of an Er:YAG laser (KEY II, KaVo, Germany) and scaling and root planing with hand instruments (SRP) to laser alone.

Material And Methods: Twenty healthy patients with moderate to advanced periodontal destruction were randomly treated in a split-mouth design with a combination of an Er:YAG laser and SRP (test) or with laser (control) alone. The used energy setting for laser treatment was 160 mJ/pulse at a repetition rate of 10 Hz.

Substantivity of toothpaste slurries and their effect on reestablishment of the dental biofilm.

Objectives: Toothpastes are good vehicles for antibacterial substances to exert a prolonged effect. This effect depends on the substantivity and ability to interfere with plaque metabolism and/or vitality. It was the purpose of this clinical, randomized 2 x 4 cell crossover study to evaluate and to compare the antibacterial effects of two toothpastes (Colgate Total(R), COL and Parodontax(R), PAR) applied as slurries on established plaque over 24 h (Part I) and their effect on 4-day plaque regrowth (Part II).

Clinical evaluation of an enamel matrix protein derivative (Emdogain) combined with a bovine-derived xenograft (Bio-Oss) for the treatment of intrabony periodontal defects in humans.

The purpose of the present study was to compare the treatment of deep intrabony defects with a combination of an enamel matrix protein derivative (EMD; Emdogain) and a bovine-derived xenograft (BDX; Bio-Oss) to BDX alone. Twenty-four healthy patients, each of whom displayed one intrabony defect, were randomly treated with a combination of EMD + BDX (test) or with BDX alone (control). Soft tissue measurements were made at baseline and 1 year following the therapy No differences in any of the investigated parameters were observed at baseline between the two groups.

Comparison of clinical, radiographic, and histometric measurements following treatment with guided tissue regeneration or enamel matrix proteins in human periodontal defects.

Background: The purpose of this study was to compare the clinical and radiographic parameters with the histometric findings following 2 different regenerative procedures in humans.

Methods: Fourteen advanced intrabony defects at teeth scheduled for extraction were randomly treated as follows: 8 with guided tissue regeneration (GTR) using bioabsorbable barriers and 6 with an enamel matrix protein derivative (EMD). Standardized radiographs, probing depths (PD), and attachment levels (CAL) at baseline and 6 months after therapy were evaluated and compared to the histometric measurements made following the removal of teeth and surrounding tissues 6 months after the surgery.

Desensitizing effects of an Er:YAG laser on hypersensitive dentine.

Aim: The aim of the present study was to evaluate and compare the desensitizing effects of an Er:YAG laser (KEY II(R), KaVo, Germany) and Dentin Protector (Vivadent, Germany) on cervically exposed hypersensitive dentine.

Method: A group of 30 patients showing a total of 104 contralateral pairs of hypersensitive and caries-free teeth was selected and randomly allocated in a split-mouth design to either (1) Er:YAG laser (80 mJ/pulse, 3 Hz), or (2) the application of Dentin Protector (polyurethane-isocyanate 22.5%; methylenechloride 77.

The effect of dental restorative materials on dental biofilm.

To investigate the arrangement of biofilms formed in vivo, volunteers wore splints with slabs of six different dental materials inserted to collect smooth surface plaque. After 5 d of undisturbed plaque accumulation, the specimens were vital stained and analyzed by the confocal laser scanning microscopy (CLSM) to evaluate the percentage of vital biofilm microflora (VF percentage). Further parameters were the area of the specimens covered by plaque (surface coating; SC, %) and the height of the biofilms (BH, pm).
