ABSTRACT
Sedation with nitrous oxide (N2O) has been widely used as a viable alternative to general anesthesia to perform dental treatments in uncooperative or anxious children. The purpose of this retrospective study is to assess if repeated sedations with N2O can improve collaboration of uncooperative children. The medical records of 650 children, aged between 3 and 14 years, who underwent at least two sedations, were consulted. Differences in the Venham score during the first sedation and subsequent sedations were collected. After removal incomplete records, 577 children's records (309 males and 268 females) were analyzed. The Venham score decreased both during each sedation and with repeated sedations (p < 0.01 for both comparisons). In particular, a significant reduction of the Venham score was observed at the first contact with the dentist, with a mean score ranging from 1.56 ± 1.46 to 1.16 ± 1.37, comparing the first and the second sedation, and from 1.65 ± 1.43 to 1.06 ± 1.30, comparing the first with the third sedation (p < 0.01). The reduction in the Venham score was recorded in both healthy and physically impaired patients, and it was significantly greater in older children than in younger children (p < 0.01). In conclusion, uncooperative children with or without physical impairments can be successfully treated with N2O sedation in order to increase their confidence in dental procedures.

OBJECTIVE: The aim of this systematic review was to explore the efficacy of different minimal invasive surgical (MIS) and non-surgical (MINST) approaches for the treatment of intra-bony defect in terms of clinical attachment level (CAL) gain and periodontal pocket depth (PPD) reduction. METHODS: A detailed review protocol was designed according to PRISMA guideline. Online search was conducted on PubMed, Cochrane library and Embase. Only randomized clinical trials (RCTs) testing MIS or MINST procedure, with or without the application of a regenerative tool for the treatment of intra-bony defect, were included. Cochrane checklist for risk of bias assessment was used. Network meta-Analysis (NMAs) was used to rank the treatment efficacy. RESULTS: Nine RCTs accounting for 244 patients and a total of 244 defects were included. Only two studies were at low risk of bias. CAL gain for included treatment ranged from 2.58 ± 1.13 mm to 4.7 ± 2.5 mm while PPD reduction ranged from 3.19 ± 0.71 mm to 5.3 ± 1.5 mm. On the basis of the ranking curve, MINST showed the lowest probability to be the best treatment option for CAL gain. Pairwise comparisons and treatment rankings suggest superiority for regenerative approaches (CAL difference 0.78 mm, (0.14-1.41); P < 0.05) and surgical treatment elevating only the buccal or palatal flap (CAL difference: 0.95 mm, (0.33-1.57); P < 0.05). CONCLUSIONS: Minimally invasive surgical (MIS) and non-surgical (MINST) periodontal therapy show promising results in the treatment of residual pocket with intra-bony defect. CLINICAL RELEVANCE: MIS procedures represent a reliable treatment for isolated intra-bony defect.

AIM: To investigate whether the height and volume of the soft tissues and peri-implant bone levels around dental implants are stable, when soft tissue augmentation has been performed. MATERIALS AND METHODS: Three operators conducted a search on electronic databases (MEDLINE, COCHRANE, EMBASE) and a hand searching on the main journals dealing with periodontology and implantology until 30 October 2014. Only articles that considered peri-implant soft tissue augmentation performed in a group of at least 10 patients and with a follow-up of at least 1 year were selected. The outcome variables were peri-implant attached/keratinized tissue width (KTW) changes, peri-implant marginal soft tissue level (PSL) changes, and peri-implant marginal bone level (PBL) changes. The review was performed according to the PRISMA statements. RESULTS: Ten articles were selected for the qualitative synthesis, but only one meta-analysis was accomplished, indicating that 1 year after implant recession coverage procedures, a mean gain of 1.65 ± 0.01 mm (90% CrI [1.44; 1.85]) was observed. CONCLUSIONS: There is no long-term evidence whether augmented soft tissues can be maintained over time and able to influence the peri-implant bone levels.
