Longevity of teeth in patients susceptible to periodontitis: Clinical outcomes and risk factors associated with tooth loss after active therapy and 30 years of supportive periodontal care.

Aim: (i) To evaluate the efficacy of active periodontal therapy supplemented by supportive periodontal care (SPC) in retaining dentition during a 30-year follow-up period in patients susceptible to periodontitis, and (ii) to assess the prognostic factors associated with tooth loss.

Materials And Methods: One-hundred and fifty-four patients with periodontitis, retrospectively classified as stage I-IV and grade B-C periodontitis, treated between 1984 and 1986 in a private practice, were enrolled in this study. After periodontal assessment, patients received non-surgical treatment followed by surgical periodontal therapy, orthodontic treatment, and tooth-splinting, where appropriate.

Effect of gingival augmentation procedure (free gingival graft) on reducing the risk of non-carious cervical lesions: A 25- to 30-year follow-up study.

Background: The aim of this long-term case series was to assess the development/prevalence of non-carious cervical lesions (NCCLs) at sites that have and have not been treated with gingival augmentation following free gingival graft (FGG).

Methods: Fifty-two patients had at least one test and one control site: 1) test site showing absence of attached gingiva (AG) associated with gingival recession (GR) treated with FGG; and 2) contralateral site with or without AG. Patient/tooth/site-associated variables were recorded for each tooth/site at baseline (T0), 12 months after surgery (T1), during the follow-up period (T2) (15 to 20 years), and at the end of the follow-up period (T3) over 25 to 30 years.

Biologic Remodeling of Periodontal Dimensions of Areas Treated With Gingival Augmentation Procedure: A 25-Year Follow-Up Observation.

Background: The role of keratinized tissue (KT) for maintenance of periodontal health has been debated for many years. This study assesses the long-term "biologic remodeling" of periodontal dimensions of teeth treated with free gingival grafts (FGGs) compared with adjacent/untreated teeth.

Methods: Seventy-four patients with at least one site showing absence or a reduced amount of attached gingiva associated with gingival recession (GR) at baseline were treated with FGGs in a private practice.

Periodontal Conditions of Sites Treated With Gingival Augmentation Surgery Compared With Untreated Contralateral Homologous Sites: An 18- to 35-Year Long-Term Study.

Background: The aim of this split-mouth study is to compare long-term (18 to 35 years) periodontal conditions of sites treated with gingival augmentation procedures (GAPs) and untreated homologous contralateral sites.

Methods: Forty-seven patients with 64 sites (test group), with lack of attached gingiva associated with recessions, were treated with marginal or submarginal free gingival grafts. Sixty-four contralateral homologous sites (control group), with or without gingival recession (GR) and with attached gingiva, were left untreated.

Periodontal conditions of sites treated with gingival-augmentation surgery compared to untreated contralateral homologous sites: a 10- to 27-year long-term study.

Background: The aim of this retrospective long-term split-mouth study was to compare the periodontal conditions of sites treated with gingival-augmentation procedures to untreated homologous contralateral sites over a long period of time (10 to 27 years).

Methods: Fifty-five subjects with 73 sites (test group) lacking attached gingiva associated with recessions were treated by means of submarginal free gingival grafts (SMFGGs) and marginal free gingival grafts (MFGGs). The 73 contralateral homologous sites (control group), with or without recession and with or without attached gingiva, were not treated.
