Chitosan-based dressing for management of palatal donor site: A randomized clinical trial.

AIMS: This study aimed to evaluate the effectiveness of a chitosan-based dressing (CD) in achieving early wound healing and hemostasis at palatal donor sites in patients undergoing free gingival graft (FGG) surgery. METHODS: Thirty-two patients requiring FGG were treated in this randomized controlled clinical trial. Complete epithelialization (CE) and color match (CM) at donor sites were assessed by a blinded examiner on postoperative days 7, 14, 21, and 28. Donor sites were compressed for 2 min with wet gauze (WG) alone in control group (CG) or WG + CD in test group (TG) immediately after graft harvesting, and immediate bleeding (IB) was recorded (yes/no). Delayed bleeding (DB) (for 1 week), and number of analgesic tablets consumed, and VAS scores for pain (for 2 weeks) were recorded by patient every day. RESULTS: Twenty-eight patients (14 in each group) were included in final analysis. The prevalence of CE (at weeks 2 and 3) and VAS scores for CM scores were higher in TG but the intergroup differences were statistically significant only for CM (at week 4). Number of patients exhibiting IB and DB was significantly fewer in the TG (p < .05). Although average pain scores and analgesic consumption were higher in TG up to 5 days, differences between two groups were not statistically significant at any time point. CONCLUSION: Our data suggests that the application of CD increased re-epithelialization and accelerated wound healing process, although it did not reach statistical significance. Moreover, CD was found to significantly reduce bleeding complications, but it did not decrease the pain levels.

Sugar-sweetened beverage consumption and socioeconomic status: A systematic review and meta-analysis.

BACKGROUND: Sugar-sweetened beverages (SSB) are an independent risk factor for obesity and other non-communicable diseases. Socioeconomic status (SES) is one of the key drivers for the purchase and consumption of SSBs among children and adults; however, there is a lack of strong evidence. This study aims to determine the association between SES and consumption patterns of SSBs across populations. RESULTS: The review was conducted according to PRISMA guidelines. PubMed, MEDLINE, Scopus, EMBASE, LILACS, Web of Science, Cochrane, and CINHAL databases were searched for relevant articles until 2022. Participants included children, adolescents, and adults who consumed different SSBs and were assessed based on their SES. The random-effects model was used to obtain the pooled odds ratio (OR). Twenty-one studies (152,070 participants) met the inclusion criteria. The risk of bias was assessed using the Newcastle-Ottawa tool, with the majority of the studies indicating medium to high quality. Eight ORs from four studies (34,454 participants) were considered for meta-analysis. Results showed those belonging to high SES had 48% lower odds of consuming the SSBs (OR 0.52; 95% CI: 0.42-0.61; p = 0.017). The overall quality of evidence was ascertained using GRADE criteria, illustrating a moderate certainty of evidence between SSB consumption and SES. CONCLUSION: Meta-analysis suggests that SES influences the consumption pattern of SSBs, with high SES having lower odds of SSB consumption.

Sugar-sweetened beverages and periodontal disease: A systematic review.

This systematic review aims to determine the association between the consumption of sugar-sweetened beverages (SSBs) and periodontal disease. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct a literature search on five electronic databases till January 2022. Systemically healthy individuals consuming SSBs and presenting periodontal disease (gingivitis/periodontitis) were included. The modified Newcastle-Ottawa Scale and the Grading of Recommendation Assessment Development and Evaluation criteria were respectively used to assess the risk of bias and the evidence's quality. Of the 1303 eligible records identified in the initial search, ten studies (nine cross-sectional and one case-control) were selected for the final review. Among the included articles, five reported SSBs intake in the form of carbonated soft drinks, two as sugary drinks, two as soft drinks, and one as coffee with added sugar. Four studies reported gingivitis as an outcome, while the remaining six studies reported periodontitis using validated indices. The included studies were of medium to high quality. Consumption of SSBs may increase gingival bleeding, thereby gingivitis and the risk of periodontitis. Intake of added sugars like SSBs should be considered as a potential factor during gingival/periodontal risk assessment. Further studies are warranted to establish additional evidence of association.

Oral mesotherapy technique for the treatment of physiologic gingival melanin hyperpigmentation using locally injectable vitamin C: a clinical and histologic cases series.

OBJECTIVES: Vitamin C (ascorbic acid) is widely used in dermatology for skin depigmentation. However, there are very few clinical studies on the efficacy of vitamin C in gingival depigmentation. This preliminary case series aims to present the clinical effectiveness, histologic changes, and patient-reported outcomes of intra-epidermal vitamin C injections (oral mesotherapy) for managing patients with gingival melanin hyperpigmentation. METHOD AND MATERIALS: Five patients were administered locally injectable vitamin C (once per week for 4 to 5 visits) in maxillary or mandibular anterior pigmented gingiva. The depigmentation effect was evaluated using the Dummett Oral Pigmentation Index (DOPI) and Gingival Pigmentation Index (GPI). Digital photographs were used to assess gingival luminescence (L*) and pigmented surface area (PSA). Parameters were recorded at baseline and at 1 and 3 months. Melanocyte histopathologic count was determined at baseline and at 3 months. Pain, gingival color change, and patient satisfaction scores were also assessed. RESULTS: Median GPI, DOPI, and PSA were significantly reduced (P ≤ .05) from baseline to 1 month. There was no statistically significant change from 1 month to 3 months. L* value significantly increased from baseline to 3 months. A median pain score of 3 (scale of 0 to 10) was observed on the day of the procedure. A score of 3 (scale of 0 to 4) was reported for the gingival color and scores 3 and 4 (scale of 0 to 4) for the overall patient satisfaction. CONCLUSION: Oral mesotherapy using locally injectable vitamin C is a nonsurgical, minimally invasive, and efficient technique for gingival depigmentation. Indian patients were satisfied with the gingival color obtained and the overall treatment experience. CLINICAL IMPORTANCE: As all the branches of medicine, specifically dentistry, direct to minimally invasive approaches, mesotherapy shows great importance to reduce the surgical interventions, especially when esthetic outcomes are needed. Oral mesotherapy using locally injectable vitamin C can be a useful nonsurgical technique for achieving gingival depigmentation in the esthetic zone.

The threshold of acceptability of excessive gingival display by laypersons: a systematic review.

OBJECTIVE: Excessive gingival display ('gummy smile') is often an esthetic concern for the patient. There is a difference in perception of smile esthetics between dentists and laypersons. Understanding what is acceptable to laypersons is critical to achieve patient satisfaction in terms of smile esthetics. The present study aimed to identify the ideal and acceptable range of excessive gingival display as defined by laypersons. MATERIALS AND METHODS: A systematic English language literature search was carried out in the following electronic bibliographic databases: PubMed, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials), Web of Science, and EMBASE, according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The quality of the articles was assessed using the AXIS tool as well as 11 additional criteria that were specifically designed for the study. RESULTS: Out of the 1263 potentially eligible articles selected in the initial search, 34 were included in the final review. A total of 16 articles identified both the ideal values and the range of acceptance of excessive gingival display, 10 only the range of acceptance, and 8 only the ideal values. From the pooled sample, the mean threshold of acceptance was -0.84 ± 1.43 mm, the range of acceptance was +3 to -2.7 mm, and the median was 0.0 mm. CONCLUSION: The present study concluded that laypersons considered minimal gingival exposure (GE) or minimal tooth coverage (TC) to be the most esthetic. However, a smile falling in the range of 3 mm of GE to 2.7 mm of TC was considered acceptable. Knowledge of laypersons' threshold of acceptance of excessive gingival display can guide clinicians in evidence-based dental esthetic treatments.

Microneedles and Nanopatches-Based Delivery Devices in Dentistry.

Needle-based devices are evolving as a promising diagnostic and therapeutic tool in the field of medicine. They can be used for drug delivery, as well as extraction of fluids, for systemic and local effects. The conventional methods of drug delivery require repeated dosing in the oral cavity due to the presence of saliva. Hence delivery systems, such as needle-based devices that could provide sustained release of the drug in the oral cavity, are required. These devices could also be a useful adjunct in diagnosis and therapy of oral cancers, delivering anti-cariogenic and antiplaque agents, for remote monitoring of oral health, and for administering painless and fearless local anesthesia. Since they offer many advantages, such as increased compliance, absence of needle phobia, they are painless, safe, self-applicable and are minimally invasive, they will have a major impact in the field of dentistry. This paper summarizes the various types of needle-based devices and their manufacturing technologies. The manuscript aims to serve as a foundational review that highlights and proposes several current and prospective impactful applications of these devices in various fields of dentistry.
