Risk factors for recurrence of periodontal disease in patients in maintenance care in a private practice.

Aim: To assess periodontal and dental conditions in individuals in maintenance care after periodontal therapy in private practice, and to identify risk factors for recurrence of disease and tooth loss.

Materials And Methods: One hundred patients attending a routine recall visit were included. All had been treated for periodontal disease and were in maintenance since ≥ 2 years.

Single or repeated antimicrobial photodynamic therapy as adjunct to ultrasonic debridement in residual periodontal pockets: clinical, microbiological, and local biological effects.

This study aims to assess in residual periodontal pockets the clinical, microbiological, and local biological effects of antimicrobial photodynamic therapy (PDT), delivered after ultrasonic instrumentation either once or twice in a 1-week interval. A single center, three-arm randomized longitudinal study was carried out for 6 months. Twenty-eight systemically healthy patients on periodontal maintenance with residual pockets (pocket depth (PD) ≥5 mm, clinical attachment loss ≥2 mm, and bleeding upon probing (BOP+)) were included.

Initial extractions and tooth loss during supportive care in a periodontal population seeking comprehensive care.

Background/aims: This retrospective survey was aimed at determining the prevalence of tooth extractions and the dental pathologies associated with them during both the active and maintenance phase of periodontal therapy in a periodontal population seeking comprehensive dental care.

Methods: A total of 273 randomly selected subjects from the oral prophylaxis clinic of the University of Berne were included. All subjects had received comprehensive care consisting of periodontal and restorative treatment and participated in a supervised maintenance program for an average of 67+/-46 months (range 5 to 278 months).

Changes in the prevalence of residual pockets and tooth loss in treated periodontal patients during a supportive maintenance care program.

Bleeding on probing and the presence of deep periodontal pockets are considered to be the best site-specific indicators for periodontal disease progression during the maintenance phase of periodontal therapy. A major emphasis of supportive periodontal care (SPC) programs, therefore, has been the control of bleeding pockets. This investigation retrospectively evaluated the changes in the prevalence of bleeding on probing, periodontal pockets, bleeding periodontal pockets and the prevalence of tooth loss in a random sample of 273 periodontal patients participating in a supportive maintenance care program at a University Clinic.

Generalizability of the added benefits of guided tissue regeneration in the treatment of deep intrabony defects. Evaluation in a multi-center randomized controlled clinical trial.

Background: Several studies have shown that GTR therapy of intrabony defects results in significantly better outcomes than access flap alone. Most of the available data, however, have been produced in highly controlled research environments by a small group of investigators. Generalizability of results to different clinicians and different subject populations has not been evaluated so far.
