RESUMO

PURPOSE: Dentin hypersensitivity (DH) is a prevalent painful condition of the teeth, the management of which lies in the obliteration of patent dentinal tubules. The purpose of this study was to compare the efficacy of 5% potassium nitrate (PN), low-level laser therapy (LLLT), and combination of low-level laser therapy and 5% potassium nitrate (LLLT+PN) in patients with fluorotic and non-fluorotic hypersensitive teeth. MATERIALS AND METHODS: Ninety self reporting patients with DH completed the randomised, double-blind study. Patients were equally divided into fluorosis group (FG), with moderate to moderately severe fluorosis and the non-fluorosis group (NFG) and subdivided into 3 groups to receive PN, LLLT (810 nm, 1 W) alone and LLLT+PN. Each participant had at least one tooth eliciting a response of ≥ 3 on a visual analog scale (VAS) to evaporative, thermal and electric tactile stimulus (digital scratch-o-meter). The teeth were evaluated at baseline, 30 min post treatment, 1 week, 4 weeks and 12 weeks. The magnitude of pressure applied by the scratch-o-meter was also assessed for all three interventions. RESULTS: Statistically, LLLT+PN was more effective in alleviating DH at all time intervals compared to baseline. However, statistically significant results (p ˂ 0.05) were seen with LLLT+PN at 12 weeks in FG. Magnitude of pressure applied showed statistically significant differences with LLLT+PN at 30 min post treatment. CONCLUSION: LLLT+PN alleviated DH at all time intervals, with a greater effect in the fluorotic group. However, LLLT+PN was more efficacious in reducing DH at 12 weeks post treatment in the fluorotic group.

RESUMO

AIM: This article reviews the issue of dental unit waterline (DUWL) contamination which affects all the clinical and hospital settings. The contaminating microorganisms commonly isolated from these settings and the most pathogenic among them have serious consequences. Over the years several measures are inculcated for decontamination of water, their advantages and shortcomings have been addressed. Options using nanotechnology which are available in the market are described briefly. MATERIALS AND METHODS: A manual and electronic search was conducted. Google and PubMed were searched for relevant material from studies up to 2013. Medical Subject Headings words looked for were "Nanotechnology," "Water purification," and "Biofilms." Reviewed findings were summarized by topic, using the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement for reporting. Seventy articles were shortlisted for articles pertaining to our topic of discussion. A systematic approach was followed by two independent reviewers and included eligibility criteria for study inclusion, data extraction, data synthesis, and drawing of conclusion. RESULTS: Dental waterline contamination is widespread in any type of dental setting having serious implications on clinicians and patients alike, especially elderly and immune-compromised. Hence, international bodies like center for disease and control and American Dental Association have come up with stringent measures for maintenance of water quality. A gamut of procedures has been tried to overcome this problem ranging from chlorinated products, water filters to the usage of distilled water. The use of nanoemulsions, nanofilters, nanomembranes, etc., and their applicability for routine usage is discussed. CONCLUSIONS: Biofilm formation in DUWLs is inevitable with the subsequent release of part of microbiota into the otherwise sterile dental settings. These consequences can be quite serious on clinicians and dental patients. Though conventional measures in water decontamination have been partly successful, the quest for more foolproof methods has led to the use of latest technology, i.e., nanotechnology. The most practical option has to be chosen based on the ease of their usage.

RESUMO

Mechanized scaling for plaque removal is a routine procedure in the practice of periodontics. Though it appears innocuous by itself, there are retinues of hazards associated with it on various organ systems in the body. Some of these unwanted effects and measures to avoid or ameliorate the same are elaborated here. Exposure to ultrasonic scaling is inevitable before any other treatment procedure. Aerosol contamination, vibrational hazards, thermal effects on the dental pulp, altered vascular dynamics, disruption in electromagnetic device, diminished hearing and dental unit waterline contamination are some of the probable off-shoots a patient has to bear. Uses of barrier devices, proper attention to usage of equipment, protection for ear and water treatment are few of solutions for the same. Though documented evidence for the existence of all effects is lacking, it is never the less significant for the overall safety of the patient. A conscientious clinician should therefore inculcate the available steps to overcome the hazards of ultrasonic scaling.
