Native vs. ribosome-crosslinked collagen membranes for periodontal regeneration: A randomized clinical trial.

Aim: To evaluate whether the ribosome-crosslinked collagen membrane (RCCM) is non-inferior to the natural collagen membrane (NCM) used in regeneration surgery in terms of clinical attachment level (CAL) gain at 6 months.

Methods: Eighty patients diagnosed as generalized periodontitis presenting with isolated infrabony defect (≥4 mm deep) were enrolled and randomized to receive regenerative surgery, either with NCM or RCCM, both combined with deproteinized bovine bone mineral (DBBM). CAL, pocket probing depth (PPD), and gingival recession (GR) were recorded at baseline, 3, and 6 months postoperatively.

The miR-223-3p Regulates Pyroptosis Through NLRP3-Caspase 1-GSDMD Signal Axis in Periodontitis.

Salivary exosomes contain various components and may play important roles in oral diseases. The purpose of this study was to verify the possible function of miR-223-3p from salivary exosomes in periodontitis. We isolated the salivary exosomes and found that the miR-223-3p content of salivary exosomes from periodontitis was less than the healthy control.

[Survey of periodontal health in medical college students after 3 years of periodontal health maintenance].

Purpose: To observe and evaluate the status of periodontal disease in young people and the effect of intervention to control the development of periodontal diseases.

Methods: One hundred and fifty-three medical college students were randomly divided into group A (receiving interventions) and group B (no interventions). They were followed up for 3 years.

Esthetic management of mucogingival defects after excision of epulis using laterally positioned flaps.

Epulis is a benign hyperplasia of the oral soft tissues. Surgical excision always extends to the periosteum and includes scaling of adjacent teeth to remove any possible irritants. The esthetics of the soft tissues may be compromised, however.

Prevalence and quantification of the uncommon Archaea phylotype Thermoplasmata in chronic periodontitis.

Objective: Chronic periodontitis is a chronic inflammatory disease of the periodontal tissues and is caused by invasion of certain types of bacteria and Archaea, with Methanobrevibacter oralis as the predominant archaeon. In this study, we investigated the prevalence and quantity of the newly discovered Archaea phylotype Thermoplasmata in patients with chronic periodontitis.

Methods: Subgingival plaque samples were obtained from 49 patients with chronic periodontitis and 45 periodontally healthy subjects.

A systematic review of visual and instrumental measurements for tooth shade matching.

Objective: Common methods for matching tooth shade can be classified into two categories: visual and instrumental measurements. This systematic review evaluated these two methods in terms of precision and accuracy using the agreement percentage rate.

Method And Materials: The following databases were searched for studies comparing different shade-matching methods: MEDLINE (PubMed), Embase, and Google Scholar.

[Factors influencing the height of gingival papilla].

Oral soft tissue has been a highlight topic these days. The morphology of gingival papilla is one of the most important factors influencing esthetics of oral soft tissue. The loss of gingival papilla height leads to black triangle.
