The digital technology rapidly evolves and new developments have resulted in further improvement of the accuracy. Future developments include the reduction of the number of steps needed from the preoperative examination of the patient to the actual execution of the guided surgery. The latter will become easier with the implementation of optical scans and 3D-printing.
No differences were detected when comparing the adjunctive use of a placebo or the investigated streptococci containing probiotic tablet after SRP. ClinicalTrials.gov Identifier: NCT02403960.
The use of a probiotic yogurt supplemented with B. animalis can have a positive effect on plaque accumulation and gingival inflammatory parameters after refraining from oral hygiene practices.
Bad breath (halitosis) is an important social complaint. In most cases (≥90%), the cause of halitosis can be found within the oral cavity. Under this circumstance, the term oral malodor applies. It affects both healthy and periodontally diseased individuals. Oral malodor is mainly caused by a microbial degradation of both sulfur-containing and nonsulfur-containing amino acids into volatile, bad-smelling gases. Anaerobic gram-negative bacteria, the same species that have been linked to periodontal diseases, are especially involved in this process, explaining why clinicians often associate oral malodor with periodontitis. Some volatile organic compounds render patients more susceptible to periodontitis and this supports the malodor-periodontitis link. This review investigates the interaction between oral malodor and periodontal diseases. Pro and con arguments regarding the mechanisms of halitosis and clinical implications will be presented. In general, however, the impact of tongue coatings has been found to be the dominant factor, besides gingivitis and periodontitis. The last part of this review discusses the treatment of bad breath, with different options.
At the moment there are no clear protocols for the assessment of bad breath. An organoleptic evaluation is still the reference. To date there are several tools available to detect and quantify specific compounds related to halitosis. This paper reviews the available information on three sulphur monitors (OralChroma™ (CHM-1), Halimeter® and Breathtron®), in order to suggest guidance for the general dental practitioner. All three devices showed an acceptable correlation with organoleptic scores. The Halimeter® and Breathtron® seem the most appropriate devices for a general dental practitioner, because they are easy to handle. Because of its capacity of distinguishing between different sulphur compounds and due to its time-consuming and complicated use, the OralChroma™ (CHM-1) seems more suitable in a research environment.
Teughels W. Clinical effects of probiotics containing Bacillus species on gingivitis: a pilot randomized controlled trial. J Periodont Res 2017; 52: 497-504.Background and Objective: Lactobacillus spp. and bifidobacteria are the most frequently used probiotics in oral health research. However, although probiotic effects have been suggested for other genera, such as bacilli, no trials are available to describe the effect of bacilli probiotics on gingivitis in humans. The aim of the present study was to evaluate the clinical effects of a bacilli-containing toothpaste, a mouthrinse and a toothbrush cleaner versus a placebo in patients with generalized gingivitis.Material and Methods: In this double-blind placebo-controlled randomized clinical trial, nonsmoking, systemically healthy patients with generalized gingivitis were included. They used a placebo or an experimental probiotic Bacillus subtilis-, Bacillus megaterium-and Bacillus pumulus-containing toothpaste, mouthrinse and toothbrush cleaner for 8 wk. Primary outcome measures of interest were plaque and gingivitis index, and the secondary outcome measures were pocket probing depth and bleeding on probing.Results: Twenty male and 20 female patients were randomized over the two groups. All participants could be included in the final analysis. Although plaque and gingivitis indices were significantly reduced after 8 wk, no intergroup differences could be found at any time point. Also, for the secondary outcome measure, intragroup but no intergroup differences could be detected. No harm or unintended effects were reported by the patients after using the study products.Conclusions: This study did not show any statistically significant differences between a placebo and a bacilli-containing toothpaste, mouthrinse and toothbrush cleaner on gingivitis parameters.
Subgingival debridement is the part of nonsurgical therapy which aims to remove the biofilm without intentionally removing the cementum or subgingival calculus. The objective of this review was to describe the end point of this therapy, the different methods used and how often it should be carried out. The literature shows that several methods are currently available for subgingival debridement, namely hand instrumentation, (ultra)sonic instrumentation, laser, photodynamic therapy and air‐polishing. None of these methods seems superior to any other regarding clinical benefits or microbiological differences. However, less treatment discomfort is reported using laser, photodynamic therapy or air‐polishing compared with hand‐ and/or (ultra)sonic instrumentation. Subgingival debridement can be carried out when, during supportive periodontal therapy, pockets of 5 mm or deeper are detected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
