AI Article Synopsis
- The study compares the effectiveness of gingival unit graft (a type of graft including the surrounding gum tissue) versus free gingival graft for treating localized gingival recession, which can cause root exposure and discomfort.
- Conducted on nine healthy patients with bilateral localized recessions, both techniques demonstrated significant improvements in clinical parameters over six months, but gingival unit graft showed better patient satisfaction and aesthetics.
- Conclusion: Gingival unit graft may offer better clinical and esthetic outcomes compared to free gingival graft for Miller Class I and II recession defects.
Article Abstract
Objectives: Gingival recession can lead to root exposure and discomfort for patients. There are various techniques for root coverage. The aim of this study was to compare the use of gingival unit graft (palatal graft including the marginal gingiva and papillae) with free gingival graft for treatment of localized gingival recession.
Materials And Methods: In this randomized controlled clinical trial, 18 bilateral localized recessions of Miller class I and II were treated in nine systemically healthy patients. Recessions were randomly treated with gingival unit graft in one side and conventional free gingival graft in the other side. Clinical parameters including clinical attachment level, keratinized tissue width, probing depth and vertical recession depth (VRD) were recorded at baseline and at one, three and six months after surgery. The healing index and patient satisfaction were also evaluated. One-way and two-way repeated measures ANOVA and paired t-test were used for statistical analyses.
Results: Both techniques caused significant improvement in clinical parameters. Gingival unit graft produced higher satisfaction esthetically (P=0.050, 0.024 and 0.024, respectively at the three time points), higher healing index (P<0.001), higher root coverage percentage at one month after surgery (34.04%, P=0.011) and greater reduction of recession width three months after surgery (P=0.007) but the reduction in VRD at this side was not significantly greater.
Conclusions: Gingival unit graft might be an acceptable modality in Miller Class I/II recession defects. This technique may have advantages over free gingival graft such as significantly superior clinical and esthetic results.

Objectives: Smoking is considered a major risk factor for periodontitis genesis and progression. In clinical studies, specific indicators have been used to characterize the smoking status of the patient as the number of cigarettes consumed (NCC), the pack-years (PY), or Fagerström Test for Nicotine Dependence (FTND). However, available literature is missing on the relationship between cotinine gingival intoxication and smoking indicators.

: Hormonal, vascular, and behavioral changes during pregnancy can negatively impact a woman's oral health, resulting in conditions such as gingivitis, dental sensitivity, and caries. Although oral health is critical during pregnancy, it remains frequently overlooked. In this study, the oral health status and hygiene practices of pregnant women attending two university hospitals in southern Italy were evaluated.

Background: Glanzmann thrombasthenia (GT) is a very rare autosomal inherited bleeding disease affecting megakaryocyte lineage with impacts on oral health such as gingival bleeding, which requires specific management protocols. Very few clinical cases have been published in the dental and hematologic literature.
Objectives: This study focuses on a series of 21 patients affected specifically by GT and their hemorrhagic prophylaxis management with the use of recombinant activated factor VII (rFVIIa) for dental extractions and full-mouth debridement.
