ABSTRACT
This study compares the clinical outcomes of Er,Cr:YSGG (2,780 nm) laser-assisted open-flap (OF) and flapless (FL) esthetic crown lengthening (ECL) for the treatment of altered passive eruption. Thirty-six healthy patients requiring ECL were randomly divided into two groups: OF and FL. Gingivectomy and ostectomy were performed with an Er,Cr:YSGG laser in both groups. The periodontal condition and gingival margin level (GML) were assessed at baseline, immediately postsurgery, and at 1, 3, and 9 months postsurgery. The effect of periodontal phenotype and tooth location on GML and supracrestal gingival tissue dimension were evaluated. A significant difference was detected in the mean of GML at all time points, except between 3 and 9 months. The main tissue rebound after 9 months was 0.25 ± 0.3 mm in the OF group and 0.26 ± 0.3 mm in the FL group (no significant difference) and was significantly higher in thick periodontal phenotypes. Er,Cr:YSGG laser-assisted ECL is a predictable technique that achieved similar outcomes using flap and flapless approaches, providing esthetic and restorative opportunities for clinicians.

UNLABELLED: Present day dental lasers can create oral environments conducive for periodontal repair. BACKGROUND AND PURPOSE: With the bacterial etiology of periodontitis and the resulting host inflammatory reaction, clinicians continue to search for therapeutic modalities to assist in the non-surgical management of periodontal disease. Traditional chairside therapies consist of mechanical debridement with manual and/or ultrasonic instrumentation with the objective of removing calculus, biofilm, and endotoxin from tooth root surfaces. Decreasing the microbial stimuli and associated end products decreases the inflammatory reaction and allows the host an opportunity to regenerate tissue through wound healing. The purpose of this article is to examine whether dental lasers, which have been in use for the past 3 decades, may augment traditional non-surgical periodontal therapy. METHODS: Review of research publications related to lasers and non-surgical periodontics with attention focused on systematic studies. CONCLUSIONS: Studies utilizing laser technology may demonstrate positive effects on 1) selectively decreasing the biofilm environment, 2) removing calculus deposits and neutralizing endotoxin, 3) removing sulcular epithelium to assist in reattachment and decreased pocket depth, and 4) biostimulation for enhanced wound healing. Comparisons of studies to determine the difference between lasers and their respective effects on the periodontium are difficult to assess due to a wide variation of laser protocols.

OBJECTIVE: To evaluate the effectiveness of a topically applied gel containing essential oils (menthol and thymol) and polyphenolic antioxidants (phloretin and ferulic acid) for reducing halitosis in dogs. ANIMALS: 20 dogs. PROCEDURES: A blinded crossover clinical trial was conducted. Dogs received a dental cleaning and examination (periodontal examination including periodontal probing and assessments of plaque, calculus, and gingivitis). Owners then applied a gel (active or placebo) to oral soft tissues twice daily for a 4-week period. Teeth of the dogs were cleaned again, and owners applied the other gel for a 4-week period. Clinicians scored halitosis immediately after the initial cleaning and at 4 and 8 weeks, and owners scored halitosis weekly. RESULTS: Halitosis assessment by clinicians revealed that both groups had improvement in halitosis scores. Two dogs were removed because of owner noncompliance. In the active-to-placebo group (n = 9), halitosis was significantly reduced during application of the active gel but increased during application of the placebo. Seven of 9 owners reported increased halitosis when treatment was changed from the active gel to the placebo. In the placebo-to-active group (n = 9), halitosis decreased during application of the placebo and continued to decrease during application of the active gel. Seven of 9 owners reported a decrease in halitosis with the active gel. CONCLUSIONS AND CLINICAL RELEVANCE: An oral topically applied gel with essential oils and polyphenolic antioxidants applied daily after an initial professional dental cleaning decreased oral malodor in dogs.

For many intraoral soft-tissue surgical procedures the laser has become a desirable and dependable alternative to traditional scalpel surgery. However, the use of dental lasers in periodontal therapy is controversial. This article presents the current peer-reviewed evidence on the use of dental lasers for the treatment of chronic periodontitis.
