The Bartholin glands, located in the base of the labia minora, have a role in vaginal lubrication. Because of the presence of other glands, removal of a Bartholin gland does not affect lubrication. Ductal blockage of these typically pea-sized structures can result in enlargement of the gland and subsequent development of Bartholin duct cysts or gland abscesses. Two percent of women will develop a cyst or an abscess in their lifetime, and physicians should be familiar with the range of treatment options. Bartholin duct cysts and gland abscesses can be treated in the office. The healing and recurrence rates are similar among fistulization, marsupialization, and silver nitrate and alcohol sclerotherapy. Needle aspiration and incision and drainage, the two simplest procedures, are not recommended because of the relatively increased recurrence rate.

Randomized Controlled Trial
OBJECTIVE
The aim of this randomised non-inferiority clinical trial was to compare the effectiveness of semi-annual (every six months) applications of 25 % silver nitrate (AgNO) solution followed by 5 % sodium fluoride (NaF) varnish to semi-annual applications of 38 % silver diamine fluoride (SDF) solution in arresting early childhood caries (ECC).
METHODS
Three-year-old children with active cavitated carious lesions were recruited and randomly assigned to two intervention groups. Children in Group A received semi-annual applications of 25 % AgNO solution followed by 5 % NaF varnish on carious lesions. Children in Group B received semi-annual applications of 38 % SDF solution followed by a placebo varnish. One trained dentist assessed ECC status at baseline and in all follow-up examinations. An independent operator performed the interventions. The dentist, the children, and their caretakers were blinded to the intervention allocation. Data were analysed using a non-inferiority test. Group A's non-inferiority would be accepted if the lower limit of the 95 % confidence interval (CI) for the difference in the mean number of arrested decayed surfaces (ds) was greater than -0.5.
RESULTS
At baseline, 1,070 children were recruited, and 535 children were assigned to each group. After 30 months, the mean arrested ds in Groups A (n = 447) and B (n = 433) were 3.7 ± 3.6 and 3.6 ± 3.7, respectively (p = 0.694). The difference in the mean arrested ds between the two groups was 0.088 (95 % CI: -0.351 to 0.526).
CONCLUSION
Semi-annual application of 25 % AgNO followed by 5 % NaF is at least as effective as the semi-annual application of 38 % SDF in arresting ECC.
CLINICAL SIGNIFICANCE
Silver and fluoride products are effective in arresting caries. As a simple, non-invasive, and inexpensive strategy, it can be used in young children, elderly adults, and people with special needs.

Review
BACKGROUND AND OBJECTIVES
Non-genital warts are benign cutaneous growths caused by infection with the human papillomavirus. Although warts can resolve spontaneously, patients might seek treatment due to discomfort or social ostracism. This review summarises high-quality studies investigating the efficacy of chemical and physical destructive wart therapies.
METHOD
We performed a literature review (up to June 2021) of published articles for wart management from MEDLINE and Embase databases. We considered systematic reviews, randomised controlled trials (RCTs), cohort studies and case series. We included studies that investigated chemical or physical destructive therapies.
RESULTS
Fifteen therapies were evaluated and included salicylic acid, cryotherapy, silver nitrate, phenol, cantharidin, glycolic acid, pyruvic acid, citric acid, formic acid, trichloroacetic acid, monochloroacetic acid, zinc, laser, surgery and electrocautery. Very few treatment options have been studied through RCTs.
DISCUSSION
To attenuate transmission, hygienic practices need to be adopted in conjunction with any treatment. Important considerations when treating patients with warts include the location of the wart, the evidence supporting the proposed treatment and potential adverse effects of treatment.

Review
Silver metal and compounds have antibacterial properties, although their action's mechanisms are not fully understood. Scientists generally consider that silver disrupts the bacterial cell wall. It causes a structural change in the bacterial cell membrane and cytoplasm. It also stops deoxyribonucleic acid replication, resulting in inactivating enzymatic activity and cell death. The antimicrobial effect of silver-containing compounds relies on the release of bioactive silver ions. Hence, silver metal and compounds have been used in medicine to prevent infection for hundreds of years. Silver metal and compounds are also used as antibacterial agents in dentistry. Studies have shown that silver compounds are effective in the management of dental caries. Fluoride-containing silver compounds have been found in experiments to be beneficial at remineralising dental cavities. Silver diamine fluoride (SDF) can assist in preventing and arresting tooth cavities. The World Health Organization included SDF in its Model List of Essential Medicine for both adults and children in 2021. Clinicians also use SDF to manage dentine hypersensitivity as well as to inhibit growth of periodontal pathogens. However, traditional silver compounds cause tooth discolouration because of the silver-staining effect. These side effects of their applications depend on the amount applied and the frequency of application. Researchers are developing nanosilver fluoride and silver nanoparticles to overcome the staining. This review gives an overview of the antibacterial mechanism of silver compounds, namely silver nitrate, silver fluoride, SDF, silver nanoparticles, and nano silver fluoride for caries management. The outlook for the future development of silver compounds will be discussed.

Review
OBJECTIVE
Minimally invasive techniques that use silver compounds and glass ionomer cement are suggested for caries management due to their effectiveness, simplicity, and low cost. The aim of this review is to examine the evidence supporting the use of silver compounds and glass ionomer cement in dentistry.
STUDY DESIGN
Literature was searched using PubMed, Elsevier, EBSCO, Google scholar, AAPD and UABC's database from 1958 to 2018 with the keywords: "Silver nitrate", "silver diamine fluoride", and "glass ionomer cement". The selected studies were then fully read to prove their relevance for this review.
RESULTS
The use of glass ionomer cement and silver compounds were shown to be effective in arresting caries. These compounds reduce cariogenic microorganisms. Their chemical properties inhibit bacterial growth while promoting remineralization. They are simpler and less time consuming than conventional restorations. They also cause less discomfort and anxiety to patients. Silver compounds were shown to stain teeth and may burn the cornea if used in high concentration. These disadvantages limit the use of silver compounds to posterior teeth and require caution when handling.
CONCLUSIONS
Minimally invasive therapies are easy to apply, non-invasive and affordable. Further studies should be done to provide more evidence of these techniques for caries management.

Review
Dentists used silver-containing solutions for deep cavity disinfection before restoration. This review aims to identify the silver-containing solutions reported in the literature for deep cavity disinfection and summarize their effects on dental pulp. An extensive search was performed using the search words "(silver) AND (dental pulp OR pulp)" in ProQuest, PubMed, SCOPUS, and Web of Science to identify English publications on silver-containing solutions for cavity conditioning. The pulpal response to the included silver-containing solutions was summarized. The initial search identified 4112 publications and 14 publications met the inclusion criteria. Silver fluoride, silver nitrate, silver diamine nitrate, silver diamine fluoride, and nano-silver fluoride were used in deep cavities for antimicrobial purposes. Indirect silver fluoride application induced pulp inflammation and reparative dentine in most cases, and pulp necrosis in some cases. Direct silver nitrate application caused blood clots and a wide inflammatory band in the pulp, whilst indirect silver nitrate application caused hypoplasia in shallow cavities and partial pulp necrosis in deep cavities. Direct silver diamine fluoride application induced pulp necrosis, while indirect silver diamine fluoride application induced a mild inflammatory response and reparative dentine formation. No evidence of the dental pulpal response to silver diamine nitrate or nano-silver fluoride was available in the literature.

It is known that silver nanoparticles (Ag NPs) and AgNO have harmful effects on the surrounding organisms, which may cause damage to these organisms. Therefore, the aim of this study is to detect damage caused by Ag NPs and silver nitrate to land slugs (). In this study, the slugs were exposed to various concentrations of Ag NPs and AgNO for 15 days. The biochemical, antioxidant, lipid peroxidation (LPO), DNA fragmentation, and histopathological endpoints were assessed after 15 days of exposure to different concentrations of Ag NPs (0.04, 0.08, 0.4, and 0.8 g/L) and silver nitrate (0.04, 0.08, 0.4, and 0.8 g/L). The results show a significant decrease in total protein, total carbohydrate, superoxide dismutase, and GST and a significant increase in total lipid, LPO, and DNA fragmentation after exposure to Ag NPs and AgNO for 15 days compared with the control group. Histopathiological alterations were observed in the digestive glands which were indicated by histochemical staining. We concluded that exposure to AgNO and Ag NPs caused oxidative stress, genetic damage and alterations in the profile of muscle proteins and histological structure in .

Review
Certain contemporary histology stains and methods are not the same as those used in the past. This progression has delved into the requirement for more precise, less complex, and efficient staining procedures. The objective of this study is to assess historical and contemporary stains and procedures, as well as the challenges surrounding their improvement. Carmine, hematoxylin, silver nitrate, Giemsa, trichome stain, Gram stain, and mauveine were among the first histological stains discovered in nature. Aside from their utility in the study of tissues at the time, they also laid the groundwork for the development of commercial dyes that are still in use today. Hematoxylin and eosin, Ziehl-Nielsen (ZN) stain, periodic acid-Schiff stain, and Grocott-Gomori methenamine silver stain are some of the most recently developed histological stains. The future of histological stains and processes appears to be influenced by technological advancements and the demand for cost-effective diagnostic approaches in the healthcare system. Thus, currently used histological stains appear to be economical, quick, and reliable tools for interpreting, archiving, and delivering essential diagnoses that could not be achieved by any other means.

Objective Management of patients with post-tonsillectomy hemorrhage (PTH) is not well defined but may include observation, topical bedside treatments, or return to the operating room. Data on the use and efficacy of silver nitrate as a topical bedside agent for the management of PTH remain unexplored. Our primary objective was to assess the efficacy of silver nitrate in reducing the need for operative control of PTH. Methods Single-institution retrospective chart review included patients aged 5-18 years who presented with tonsillar bleeding within 30 days of tonsillectomy. Patients undergoing observation or bedside silver nitrate cautery were compared based on clinical characteristics and experience of the physician performing the procedure. The outcome of interest was rebleeding requiring operative control. Sample characteristics according to treatment modality were described using Fisher's exact tests and ANOVA. Results Of the patients eligible for inclusion, 29 (20%) were observed and 70 (48.3%) were treated with topical silver nitrate. Age was the only statistically significant clinical difference among treatment groups. The silver nitrate group had more patients who underwent operative control of PTH compared to the observation group (p = 0.004). When comparing the need for operative control between the observation group and patients who had initial success with silver nitrate, there was no difference (p = 0.29). No differences were found in the rate of bleeding requiring operative control when comparing experience of the physician performing the procedure (p = 0.20). Conclusion More patients who underwent silver nitrate cautery required PTH control in the operating room compared to the observation group. This may be due to patient selection as our results also suggest that there is no statistical difference in rates of operative control of PTH when comparing initial successful treatment with topical silver nitrate to observation. Age is likely a factor that was used by physicians in this study to decide the initial management of PTH. Provider experience does not appear to affect rebleeding rates. Future studies are necessary to evaluate the clinical impact of silver nitrate in the context of PTH and will benefit from more robust sample sizes and enhanced diversity in the sample group.
