The adjunctive use of EOs may promote significant CAL gain and PPD reduction in deep residual pockets.

The primary stability of dental implants is fundamental for osseointegration. Therefore, this study aimed to assess the correlation between insertion torque (IT) and resonance frequency analysis (RFA) of implants placed in mandibles and maxillas of different bone densities. Eighty dental implants were placed in maxillas and mandibles, and IT and the implant stability quotient (ISQ) were measured at the time of implant insertion. Bone density was assessed subjectively by the Lekholm and Zarb index. The type I and II densities were grouped together (group A)as were the type III and IV densities (group B). The IT in group A was higher (Student t test, P = .0013) than in group B (46.27 ± 18.51 Ncm, 33.62 ± 14.74 Ncm, respectively). The implants placed in group A showed higher ISQ (Student t test, P = .0004) than those placed in group B (70.09 ± 7.50, 63.66 ± 8.00, respectively). A significant correlation between IT and the ISQ value was observed for group A (Pearson correlation test; r = 0.35; P = .0213) and for group B (r = 0.37; P = .0224). Within the limitations of this study, it was possible to conclude that there is a correlation between IT and RFA of implants placed in mandibles and maxillas of different bone densities.

This randomized clinical trial investigated the effect of a dentifrice containing triclosan on the reduction of dental plaque and gingivitis in institutionalized individuals with cerebral palsy. Fifty-seven residents were randomly allocated to a test group (n=28, dentifrice with triclosan) and a control group (n=29, conventional dentifrice). A single calibrated investigator performed examinations at baseline and after three months. The amount of dental plaque was assessed, and gingivitis was measured. The caretakers performed brushing with dentifrice. After three months, there was a significant reduction in the plaque index in both groups, but there was no difference between the two groups. There was a significant reduction in gingivitis only in the test group, and the difference between groups was significant after three months. The authors concluded that the dentifrice with triclosan reduced interdental bleeding in the studied population.

The conventional method of ridge expansion uses a mucoperiosteal flap elevation to allow bone corticotomy, which is followed by bone expansion performed with chisels and bone expanders. To facilitate corticotomy and avoid flap elevation, bone expansion can be performed in 2 stages. This case report presents a modified 2-stage bone expansion technique to achieve better implant stabilization and wound closure. This modified approach may be an efficient procedure for minimizing complications.

The aim of this study was to evaluate the clinical effect of ultrasonic instrumentation irrigated with essential oils in the reduction of sites with a probing depth of 5 mm or more. For this purpose, a randomized, double-blind, parallel-arm and placebocontrolled clinical trial was conducted. Sixty-four individuals with chronic periodontitis were invited to participate in this study. The patients were randomly allocated to the test group (irrigation with essential oils containing 0.064% Thymol, 0.092% Eucalyptol, 0.06% Methyl Salicylate, 0.042% Menthol and 21.6% Alcohol) or control (irrigation with placebo, 21% alcoholic solution). Probing pocket depth (PD), clinical attachment level (CAL), gingival recession (R), bleeding on probing (BOP) and plaque index (PI) were assessed. The individual was considered the statistical unit. The differences between the groups and the alterations over the course of time were analyzed according to a generalized linear model (repeated measures analysis of variance). There was a significant reduction in PD (1.59mm test and 1.16mm control) and BOP (44.4% test and 52.62% control) and CAL gain (1.15mm test and 0.91mm control) in both groups (p<0.001). However, there was no difference between groups at the end of the trial. When sites with PD >7mm at baseline were analyzed, a significant reduction in PD was observed in test (1.60mm, p = 0.004) and control groups (1.10mm, p = 0.0008), as well as a significant gain in CAL in test group only (test: 1.59mm, p<0.001; control: 0.71mm, p=0.051). There was a significant difference between the groups after 24 weeks (p=0.02). It was concluded that subgingival ultrasonic instrumentation in residual pockets promoted reduction in PPD, BOP and gain in CAL. Besides, adjunctive irrigation with essential oils promoted additional benefits in gain of CAL in sites with initial pockets > 7mm, when compared to test group.
