Long-term stability of intrabony defects treated with minimally invasive non-surgical therapy.

Aim: The aim of this study was to assess the stability over time of periodontal intrabony defects treated with minimally invasive non-surgical therapy (MINST) and supportive periodontal therapy (SPT).

Methods: Clinical and radiographic analysis was carried out in 21 intrabony defects treated with MINST in 14 consecutive patients included in a prospective study and reassessed after 5 years of SPT. Baseline, 1- and 5-year radiographs were analysed, and bone levels were compared by multilevel linear regression adjusted by latent variable method.

Minimally invasive non-surgical approach for the treatment of periodontal intrabony defects: a retrospective analysis.

Aim: The aim of this retrospective analysis was to assess healing of intrabony defects treated with minimally invasive non-surgical therapy (MINST).

Methods: A retrospective analysis was carried out in 35 consecutive intrabony defects treated by MINST (without any adjuncts) in 23 non-smoking patients. All defects had a radiographic intrabony component > 3 mm and had clinical and radiographic data available at baseline and 12 after treatment.

Clinical and radiographic outcomes following non-surgical therapy of periodontal infrabony defects: a retrospective study.

Background And Aim: The aim of this retrospective study was to analyse the clinical and radiographic response of infrabony defects following non-surgical therapy and to detect the factors associated with such a response.

Materials And Methods: Clinical and radiographic data were retrieved from 143 consecutive patients treated with non-surgical periodontal therapy and re-assessed by the same clinician. Linear radiographic measurements of infrabony periodontal defects were performed on baseline and follow-up (12-18 months post-treatment) radiographs.

Latent variable approach to correct errors in radiographic measurements.

Radiographic outcomes are important for the diagnosis and treatment of periodontal diseases. However, the assessment of radiographic measurements is affected by many factors, and it is therefore difficult to ascertain changes in radiographic outcomes. In this study, we proposed a latent variable approach to correct for the distortion in the radiographic measurements in pairs of periapical radiographs taken before and after periodontal treatment.
