Steroidal dexamethasone is as effective as non-steroidal ibuprofen for preventing or controlling postoperative pain and discomfort after surgical implant placement.

Abstract
Aim: The aim of this study was to investigate the consequences of different flapless procedures for the installation of dental implants on peri‐implant bone response.
Materials and methods: After bilateral extraction of the mandibular second and third premolars and a 3‐month healing period, 30 SLActive® implants were installed for 3 months in 10 Beagle dogs according to three different surgical approaches, i.e.: (1) flapped (F), (2) tissue punch flapless (P), and (3) direct flapless (DF).
Results: At harvesting, 29 implants were analysed. Micro‐computed tomography and histomorphometrical evaluation (which also included the mobile implants) showed comparable results in bone volume (F=55 ± 9, P=51 ± 4, DF=54 ± 5) and crestal bone level (F=3420 ± 762, P=5358 ± 1681, DF=3843 ± 433). However, the implants inserted using the punch approach revealed a significantly lower first bone contact (F=3420 ± 762, P=5358 ± 1681, DF=3843 ± 433) and bone‐to‐implant contact percentage (F=70 ± 12, P=48 ± 23, DF=73 ± 12). Considering the gingival response, the barrier epithelium was also significantly deeper around the implants installed using the punch approach (F=1383 ± 332, P=2278 ± 1154, DF=1107 ± 300).
Conclusions: The results indicate that a flapless surgical technique can be used for the installation of oral implants. In addition, using a tissue punch wider than the implant diameter should be avoided, as it can jeopardize the outcome of the implantation procedure.
This study gives sufficient evidence to suggest that the oral health status of this disabled population was poor and there was an increased unmet dental treatment needs.
This study showed that Straumann Bone Level and OsseoSpeed implants induced similar bone response after immediate implantation at 4 and 12 weeks. The immediate implant placement resulted in peri-implant crestal bone-level changes for both types of implants.
A systematic review and meta‐analysis was performed to understand the efficacy of xenogeneic collagen matrix (CMX) compared with connective tissue graft (CTG) for the treatment of multiple adjacent gingival recessions (MAGRs). A literature search was performed for published randomized controlled trials in adult patients (≥18 years old) with Multiple Adjacent Miller class I and II gingival recessions (MAGRs). The assessments included recession depth, Recession width, complete root coverage, mean root coverage, probing depth, clinical attachment level, and keratinized tissue width. Pooled data were analyzed using fixed‐ and random‐effects models, and Forest plots were constructed. Heterogeneity within studies was calculated to assess publication bias. Four randomized controlled trials were included based on the eligibility criteria. Although the recession depth, complete root coverage, and mean root coverage were significantly lower with CMX (p = .017 and p = .001, p = .001, respectively), there was no statistically significant difference in the Recession width between CMX and CTG (p = .203). CMX showed significantly lower Probing Depth than CTG (p = .023); however, no significant difference in clinical attachment level (p = .060) and keratinized tissue width (p = .052) was observed between the groups. Owing to the heterogeneity in the included studies, firm conclusions cannot be drawn regarding the noninferiority of CMX compared with CTG. Long‐term studies are therefore needed to conclusively establish the relative efficacy of CMX in MAGR.
Objectives
To assess the relationship between the presence of periodontal disease and halitosis.
Methods
A total of 120 patients were enrolled and divided into 2 groups, 60 patients with probing depth (PD) > 3.0 mm (group 1) and 60 patients with PD ≤ 3.0 mm (group 2). Clinical parameters including, plaque index (PI), bleeding index (BI), and PD were obtained. Breath samples were collected and analyzed using a portable gas chromatograph to measure the concentration of volatile sulfur compounds (VSC).
Results
Halitosis was found to affect 58.3% of the total patients. The means of PI, BI, and VSC were significantly higher in group 1 (PD > 3.0 mm) than in group 2 (PD ≤ 3 mm).
Conclusions
The percentage of patients suffering from halitosis in the Saudi population are comparatively high. In addition, there was a positive association between periodontal disease and halitosis.
Background/purpose
Halitosis is the unpleasant and offensive odour in exhaled air, which is linked to the presence of volatile sulphur compounds (VSC). Different mouthwashes have been used to treat halitosis. The objective of this study was to test the effect of an antioxidant (AO) mouthwash, and mouthwash containing [0.05% chlorhexidine, 0.05% cetylpyridinium chloride, and 0.14% zinc lactate (CHX-CPC-Zn)] on VSC.
Material and methods
Thirty-five subjects with halitosis participated in this clinical trial. At the baseline visit, a breath sample was taken and analyzed for the level of hydrogen sulphide (H
2
S), methyl mercaptan (CH
3
SH), and dimethyl sulphide (CH
3
SCH
3
) using portable gas chromatography (OralChroma™). Two mouthwashes were randomly provided to each subject in addition to saline solution (NaCl 0.9%) as control. Subjects were instructed to rinse with 20 ml of the mouthwash for 1 min twice daily for 2 weeks. At second visit, post-treatment breath sample was taken. Afterward, the patient was asked to refrain from using mouthwash for a washout period of 1 week. A similar procedure was repeated for each mouthwash interval.
Results
No significant differences in VSC level between all three groups were detected at baseline. A significant reduction in VSC level was obtained after using CHX-CPC-Zn mouthwash. On other hand, both AO mouthwash and saline had no significant impact on the level of VSC.
Conclusion
CHX-CPC-Zn mouthwash has a significant effect on VSC level reduction in subjects with confirmed halitosis. Besides, using AO mouthwash regularly for 2 weeks did not have any impact on improving the level of halitosis.
GaAlAs diode laser irradiation of diseased periodontal pockets at 685 nm and 1.6 J cm seemed to be an effective adjuvant to mechanical instrumentation to treat chronic periodontitis.
