Partial-mouth periodontal examination protocols for the determination of the prevalence and extent of gingival bleeding in adolescents.

Objective: To compare the performance of partial-mouth periodontal examination (PMPE) protocols with different cut-off points to the full-mouth examination (FME) in the assessment of the prevalence and extent of gingival bleeding in adolescents.

Methods: A cross-sectional study was conducted involving 12-year-old adolescents. Following a systematic two-stage cluster sampling process, 1134 individuals were evaluated.

Impact of Partial-Mouth Periodontal Examination Protocols on the Association Between Gingival Bleeding and Oral Health-Related Quality of Life in Adolescents.

Background: It is not clear how using partial-mouth periodontal examination (PMPE) protocols affects estimates of the association between gingival bleeding (GB) and oral health-related quality of life (OHRQoL). The aim of the present study is to assess impact of different PMPEs on the association between GB and OHRQoL in 12-year-old adolescents.

Methods: A total of 1,134 adolescents were evaluated for clinical and subjective variables.

Effectiveness of a desensitizing agent for topical and home use for dentin hypersensitivity: a randomized clinical trial.

Purpose: To evaluate the effectiveness of a desensitizing gel for topical and home use for the treatment of dentin hypersensitivity (DH) by means of a 3-arm parallel, randomized, double blind clinical trial.

Methods: 107 participants were allocated to three groups: placebo gel (PG), test gel (TG) (5% sodium fluoride, 5% potassium oxalate, 10% strontium chloride) and 2% sodium fluoride gel (FG). DH measurement was performed by a single blind examiner by means of the visual analog scale (VAS) after tactile (blunt tipped probe), thermal (air blast) and osmotic (water blast) stimulus at time intervals of baseline, 7, 15 and 30 days.
