Etiology and characteristics of halitosis in patients of a halitosis center in Northern Italy.

Background: As there are few studies in Europe describing characteristics of breath malodor for large groups of patients, this retrospective study was designed to analyse the etiology of halitosis among patients attending a breath malodor center in Northern Italy.

Methods: Clinical records of 547 consecutive patients were reviewed and data on self-perceived halitosis, organoleptic scores, volatile sulphur compound (VSC) levels, and oral health condition were extracted and analysed.

Results: The prevalence of intra-oral halitosis was 90.

Clinical evaluation of the effectiveness of enamel matrix proteins and autologous bone graft in the treatment of mandibular Class II furcation defects: a series of 11 patients.

The purpose of this study was to evaluate the results of treatment of buccal mandibular Class II furcation defects with a combination of autologous bone grafts and enamel matrix derivative over a 24-month period. Eleven individuals with chronic periodontitis were selected and contributed one furcation defect each. Statistically significant improvements in mean vertical probing attachment level and horizontal probing attachment level were obtained at the 2-year evaluation.

Clinical and radiographic evaluation of the effects of guided tissue regeneration using resorbable membranes after extraction of impacted mandibular third molars.

The aim of this investigation was to evaluate the healing following guided tissue regeneration of bone defects distal to the mandibular second molars after surgical extraction of soft tissue-impacted, mesioangularly inclined third molars. After the impacted third molars were extracted, 15 sites were treated with polyglycolic acid/polylactic acid bioresorbable membranes plus scaling and root planing (SRP) of the distal surface of the second molars (test sites); 15 sites were treated with SRP alone (control sites) according to a split-mouth design. At 12 months after surgery, the placement of barrier material was shown to have resulted in statistically significant differences in clinical attachment level and bone gain compared to control sites.
