Comparison of Vantej and Dente 91 Toothpastes in the Management of Dentin Hypersensitivity: A Randomised Clinical Trial

Introduction: Dentinal hypersensitivity is a prevalent and distressing dental condition characterised by acute, transient pain or discomfort arising from exposed dentin in response to external stimuli, such as variations in temperature, mechanical stimuli, or consumption of acidic or sweet foods. Dentinal Hypersensitivity (DH) impacts daily activities, such as eating, drinking, and oral hygiene practices. Dentifrices are commonly used in the treatment of hypersensitivity, as they relieve sensitivity by obstructing nerve pathways through the formation of compounds. Aim: The aim of the study is to evaluate and compare the efficacy of two types of desensitising toothpastes, Vantej and Dente 91, in treating DH. Materials and Methods: A randomised controlled clinical trial was conducted with 40 patients who had a minimum of two hypersensitive teeth. The clinical investigation took place in a dental set-up in Bhubaneswar, Odisha, from July to August 2022. The patients were randomly allocated to two groups (20 in each group) in a 1:1 ratio for the Vantej and Dente 91 groups. Over a four-week period, the patients were instructed to use the prescribed toothpaste twice daily. DH assessment techniques included a Verbal Response Scale (VRS), air blast stimulation, and cold stimulation, both at baseline and after the four-week duration. Statistical analyses were performed using the Mann-Whitney U test and Wilcoxon signed-rank test, with the significance level set at p<0.05. Results: The fourth-week scores compared to baseline scores for the verbal scale, air blast stimulus, and cold sensitivity methods in both groups showed a reduction in DH. In the inter group comparison, the Dente 91 group exhibited greater effectiveness compared to the Vantej group, with a significant reduction in VRS (p=0.02) and air blast stimulus (p=0.01), but not in cold sensitivity (p=0.09). Conclusion: Both Vantej and Dente 91 toothpastes significantly reduced dentinal hypersensitivity. However, the percentage reduction was higher in the latter group, suggesting more effective management of DH. Dente 91 could be considered a promising alternative to the existing over-the-counter desensitising toothpastes.

PHOTOBIOMODULATION IN DENTISTRY: A REVIEW OF THE LITERATURE

Photobiomodulation therapy (PBMT), is the ability to modulate cell growth, survival, and differentiation processes of cells using optimal amount of energy ,not causing phototoxicity . It includes a wide range of electromagnetic wavelengths such as broadband lights, LEDs, and lasers that may have both photo stimulation and photo inhibitory effects on the target tissues, each of which can be used in therapeutic applications. Some of the benets of using PBMTin dentistry include reducing dentin sensitivity to tactile and thermal stimulations, improving dentin formation from dental pulp, reducing inammation of oral mucosa, accelerating bone formation, reducing pain after all types of dental treatments, and improving wound healing processes. In this review of literature, we emphasize that PBMT itself or as an adjunct can have a crucial role in decreasing postoperative dental pain, increasing depth of anesthesia during cavity preparation, decreasing tooth hypersensitivity, reducing inammation of the tissues, and healing of denture stomatiti

The potential of Robusta (Coffea canephora) green beans as a dentin hypersensitivity therapy agent: A review

Dentin hypersensitivity or sensitive teeth is one of the most disturbing diseases caused by the opening of the dentinal tubules which can transmit fluid to the pulp nerves of the tooth, so that patient feel a short and sharp pain when exposed to triggering agents. This can cause physical and psychological problems for the patient. In addition, it can have a negative impact on a person's quality of life, especially regarding food selection, plaque control methods, and aesthetic aspects. One of the treatments for dentine hypersensitivity is by using materials that contain a desensitizing effect, such as stannous, strontium, potassium, arginine, oxalate, and hydroxyapatite. These ingredients can be contained in toothpaste, serum, mouthwash and in dental office materials. Robusta green beans is known to contain fluoride and oxalic acid. Fluoride is needed by the teeth to prevent and repair porous teeth, cavities to hypersensitive teeth. While oxalic acid is a material that has a desensitizing effect, which can be used to treat dentine hypersensitivity. However, the content of oxalic acid and fluoride in Robusta green bean has not been studied further to determine its desensitization potential. This review article will discuss the possible desensitization potential of Robusta green bean.

The Efficacy and Durability of Three Desensitising Agents for Management of Hypersensitive Teeth: An In Vitro Study

Introduction: Dentine hypersensitivity (DH) is a brief and acute pain produced when dentine is subjected to various stimuli. The treatment for DH has been classified by mode of delivery as at- home and in-office therapy. It was proven that desensitising agents have the capacity for occluding dentinal tubules. The purpose of this study was to evaluate the efficacy and durability of desensitising agents for management of DH. Methods: Twelve non-carious extracted human permanent premolars were sectioned into dentine layer. The dentine disc specimens were divided into four groups. Each group were applied with 8% arginine-calcium toothpaste, 0.24% sodium fluoride toothpaste, 5% potassium nitrate toothpaste and distilled water respectively. Scanning Electron Microscope (SEM) is used to evaluate the magnitude changes of dentinal tubules post treatment with the desensitising toothpastes in terms of the efficacy and durability at day one, week one and week three after application. The data will be analyzed by analysis of variance (ANOVA) using the Statistical Package for the Social Sciences (SPSS) software (version 19.0). Results: All toothpastes demonstrated significant dentinal tubule occlusions. However, 8% arginine-calcium toothpaste showed the greatest percentage of occlusion at day one followed by potassium nitrate toothpaste and sodium fluoride toothpaste. After three weeks, 8% arginine-calcium toothpaste remained the greatest percentage of dentinal tubules occlusion Conclusion: The result revealed that 8% arginine-calcium toothpaste is the most efficient and has longer durability among the other toothpaste. Therefore, with this finding it could help the patient for selection of desensitising toothpaste in managing the DH.

Assessment of early wound healing, pain intensity, quality of life and related influencing factors during periodontal surgery: a cross-sectional study

This cross-sectional study assessed early wound healing, pain intensity, quality of life, surgical satisfaction, and related factors during periodontal surgery. A total of 369 patients completed the questionnaire before undergoing periodontal surgery (baseline), immediately after the operation (phase I), on the day of suture removal (phase II), and one month later (phase III). The Early Wound Healing Score (EHS) was assessed, and the short-form McGill Pain Questionnaire (SF-MPQ), tooth hypersensitivity visual analog scale (VAS), oral health-related quality of life measure (OHQoL-UK), and surgical satisfaction VAS were administered and analysed. The EHS was 8.41 ± 2.74 and was influenced by disease severity and surgical factors. Scores on the SF-MPQ, pain intensity scores, and OHQoL-UK scores were significantly increased in phase I and decreased later. Tooth sensitivity decreased significantly one month after periodontal surgery. Psychological factors were positively related to SF-MPQ, pain intensity, OHQoL-UK and tooth sensitivity VAS scores in all phases, while disease severity and surgical factors were only related to these scores at baseline or in phases I/II/III. Surgical acceptance and reoperation willingness continuously decreased after surgery, and all these scores were related to surgical satisfaction. EHS, pain intensity and quality of life were closely related to disease severity, psychological factors and surgical factors in phase I (i.e., immediately after surgery). The findings suggest that surgical details should be enhanced and that behavioural and psychological interventions measures should be implemented to improve outcomes during periodontal operation and during the early postoperative period as well as to improve patient-oriented periodontal surgery experiences. Trial registration This cross-sectional study did not include interventions with human participants, and all the experimental procedures involving humans in this study were approved by the Ethics Committee of West China College of Stomatology, Sichuan University (WCHSIRB-D-2020-284).

Effectiveness of 38% Silver Diamine Fluoride in Reducing Dentine Hypersensitivity on Exposed Root Surface in Older Chinese Adults: Study Protocol for a Randomised Double-Blind Study

Background: Dentine hypersensitivity on an exposed root surface induces pain, affects daily oral hygiene practice, limits dietary choices and negatively affects quality of life. Silver diamine fluoride is marketed in the United States as a desensitising agent, but well-designed clinical trials are limited. This study evaluates the anti-hypersensitivity effect of silver diamine fluoride on hypersensitive teeth due to an exposed root surface in older Chinese adults. Methods/design: We will conduct a randomised double-blind clinical trial with a sample size of at least 148 Chinese older adults aged 65 or above who have dentine hypersensitivity due to an exposed root surface. We will collect written consent before the study. A trained examiner will examine the participants’ teeth with a blast of compressed air from a 3-in-1 syringe. Those adults who report a self-perceived sensitivity score (SS) (0 to 10) of 8 or more on at least one tooth with an exposed root surface will be recruited. The recruited older adults will be randomly allocated into two groups using a block randomisation of six. Group 1 participants will receive the application of 38% silver diamine fluoride solution every 4 weeks. Group 2 participants will receive the application of 5% potassium nitrate solution every 4 weeks. Dietary advice, oral hygiene instruction and fluoride toothpaste at 1450 ppm will be provided to participants in both groups. The same trained examiner will perform follow-up examinations for the participants and determine the dentine hypersensitivity in SS of the most hypersensitive tooth (with the highest pre-treatment SS) immediately after the intervention and at 4-week and 8-week intervals. Discussion: There is no consensus on the standard of care for a professionally applied desensitising agent in older adults. This trial will provide evidence for clinicians to devise an effective dental care plan for older adults with dentine hypersensitivity. Trial registration: NCT05392868 Registered on 22 May 2022.

Silver diamine fluoride therapy for dental care.

Silver diamine fluoride (SDF) was developed in Japan in the 1960s. It is used to control early childhood caries, arrest root caries, prevent fissure caries and secondary caries, desensitise hypersensitive teeth, remineralise hypomineralised teeth, prevent dental erosion, detect carious tissue during excavation and manage infected root canals. SDF is commonly available as a 38% solution containing 255,000 ppm silver and 44,800 ppm fluoride ions. Silver is an antimicrobial and inhibits cariogenic biofilm. Fluoride promotes remineralisation and inhibits the demineralisation of teeth. SDF also inactivates proteolytic peptidases and inhibits dentine collagen degradation. It arrests caries without affecting dental pulp or causing dental fluorosis. Indirect pulp capping with SDF causes no or mild inflammatory pulpal response. However, direct application of SDF to dental pulp causes pulp necrosis. Furthermore, SDF stains carious lesions black. Patients must be well informed before SDF treatment. SDF therapy is simple, painless, non-invasive, inexpensive, and requires a simple armamentarium and minimal support. Both clinicians and patients generally accept it well. In 2021, the World Health Organization included SDF as an essential medicine that is effective and safe for patients. Moreover, it can be used for caries control during the COVID-19 pandemic because it is non-aerosol-generating and has a low risk of cross-infection.

Efficacy of fluoride varnish containing xylitol coated calcium phosphate or potassium nitrate gel versus conventional fluoride varnish in management of hypersensitivity of exposed root surfaces in adult patients: A randomized clinical trial

Objective: This clinical trial was conducted to compare the efficacy of fluoride varnish containing xylitol coated calcium and phosphate or potassium nitrate gel versus conventional fluoride varnish in the management of hypersensitivity of non-carious exposed root surfaces in adult patients. Material and Methods: 35 patients having 105 hypersensitive teeth were randomly allocated to be treated either using Embrace varnish (PULPDENT Corporation, Watertown, MA, USA) or UltraEz gel (Ultradent Products Inc. South Jordan, UT, USA) or Fluoride varnish FluoroDose (Centrix Inc., Milford, Connecticut, USA), all agents were used according to the manufacturers’ instructions. Hypersensitivity scores were assessed using the visual analogue scale (VAS), after applying different stimuli. The assessment was done at baseline, after 4 hours of application, after two days, then after 4, 8 and 12 months. Results: UltraEZ gel showed the best immediate relief with a significant difference from other treatment methods, fluoride varnish showed the best relief at both short and long term follow up periods. Embrace varnish showed the least success in reducing hypersensitivity. Conclusions: Fluoride varnish showed the best reduction in hypersensitivity values while UltraEZ showed the best immediate relief and Embrace varnish showed the least efficacy

Awareness of Polish society about complications and contraindications in teeth whitening

Introduction and aim: Teeth whitening, which has a positive effect on the quality of life and the human psyche but is associated with side effects and contraindications, is becoming increasingly popular and widespread. The aim of the study was to collect and analyse data concerning the awareness of the Polish population of complications and contraindications to tooth whitening.
 Material and methods: A survey was conducted using a Google document among teeth whitening and non-whitening individuals. Link to the survey posted on various social groups.
 Results: People who whiten their teeth in a dental office are the group that showed the highest awareness about the side effects and contraindications of teeth whitening. People who do not whiten their teeth are more aware than people who whiten outside the dental surgery. The popularised slogans such as the possibility of tooth hypersensitivity, weakening of the enamel or the necessity to follow a "white diet" are known to each study group. The issues connected with the dentist's office were the least popular - persons whitening their teeth outside the dentist's office are not aware of the necessity to professionally clean their teeth before this procedure. None of the study groups have knowledge about the temporomandibular joint problem as a contraindication to teeth whitening.
 Conclusions: The Polish population shows an average knowledge of teeth whitening. The basic contraindications and complications are known to a broader group of respondents, but there are aspects of whitening about which the knowledge of respondents is low and requires popularisation. In addition, the survey indicates that more research is needed into the relationship between the temporomandibular joint and tooth whitening.

ИССЛЕДОВАНИЕ РАСПРОСТРАНЕННОСТИ И ХАРАКТЕРА ГИПЕРЕСТЕЗИИ У ЖИТЕЛЕЙ ПОЖИЛОГО ВОЗРАСТА ВАСИЛЕОСТРОВСКОГО И ПЕТРОГРАДСКОГО РАЙОНОВ САНКТ-ПЕТЕРБУРГА

Abstract. Hypersensitivity of teeth pose an ineresting question in the practice of the dentist because of its high prevalence and polyetiological nature. The aim of the work was to establish the incidence of tooth hyperesthesia among elderly residents of Vasileostrovsky and Petrogradsky districts of St. Petersburg. The study involved 117 participants of both sexes, divided into 2 age groups (55-64;65-75). 70 patients with hypersensitivity of teeth tissues were detected. In addition to establishing the fact of hyperesthesia, patients were interviewed, teeth were examined for the presence of carious and non-carious lesions, the states of oral hygiene and periodontal tissues were evaluated using dental indices. To determine the general condition of the patient's oral health we used: OHI (simplified Green-Vermillion index, (Green, Vermillion, 1964)) - to determine the level of oral hygiene, PI index (P.A. Leus, 1988) - to determine the presence of symptoms of periodontal pathology, DMF (Klein, Palmer, 1937) - to determine the degree of dental caries. Assessment of dental hyperesthesia was carried out using indices of prevalence (IPDH) and intensity (IIDH) of dental hyperesthesia. According to the results of the examination the following conclusions were made: the most susceptible to hyperesthesia were women from 55 to 64 years old (44,28% of all those examined). An unsatisfactory level of hygiene, an average degree of periodontal disease and a high degree of caries intensity were detected, a limited form of hyperesthesia was more frequent (56.81% of all cases) with a reaction to all types of stimuli(63.02% of all cases), a moderate level of tooth sensitivity efficiency was noted(56.5%). The results of the survey showed that many patients do not maintain the necessary level of oral hygiene, rarely visit the dentist and are dissatisfied with their oral health.

Management miller class I recession with platelet rich fibrin and coronally repositioned flap

Background: Gingival recession is associated with root exposure, often leading to hypersensitivity concerns esthetically and difficulty maintaining optimum oral hygiene. Several surgical procedures have been suggested to treat gingival recessions. Objective: This treatment is done to eliminate tooth hypersensitivity and to get ideal crown proportion with coronally repositioned flap. Method and Treatment Result: Dental health education (DHE) and scaling root planning (SRP) was completed before the coronally repositioned flap procedure. In result, gingival recessions and tooth hypersensitivity was reduced significantly. Conclusion: Platelet rich fibrin and coronally repositioned flap is the appropriate technique to treat miller class I recession.

A cross-sectional study on COVID-19-related changes in self-medication with antibiotics.

Dental treatments have been limited to emergency care in many countries worldwide due to the global rapid spread of coronavirus disease-2019 (COVID-19). Fear of contracting the disease in dental clinics has also altered the pattern of dental visits and self-medication. The present study compared self-medication with antibiotics (SMA) and the pattern of dental visits before and after the emergence of COVID-19 pandemic in a referral dental clinic in the north of Iran. The data for the present cross-sectional study was collected from 756 patient records retrieved from the archives of the Faculty Clinic of Rasht School of Dentistry during two separate periods: before the COVID-19 pandemic from mid-November 2019 to mid-February 2020, and after the pandemic emergence from mid-April to mid-July 2020. In addition to demographic variables namely age, gender, and place of residence of patients, their smoking status, chief complaint, and SMA were also extracted from patient records. The Chi-square test and binary logistic regression models with 95% confidence interval served for statistical analysis. In total, 756 patient records (412 records from the pre-pandemic period and 344 records from the post-pandemic period) were evaluated. SMA was significantly more prevalent after the pandemic compared to that before pandemic (OR = 3.39, 95% CI = 2.43-4.73, P<0.001). The number of patients who smoke significantly decreased after the pandemic by 6.6% compared to that in pre-pandemic period. Dental pain, pus discharge, and abscess as the chief complaints of patients were significantly more prevalent during the post-pandemic period; while, dental checkups, tooth hypersensitivity, and esthetic dental problems were significantly more frequent as the chief complaints of patients during the pre-pandemic period. There is indication that during the COVID-19 pandemic, SMA and prevalence of acute dental problems in patients have increased. With regard to the consequences of SMA, there is a need to raise public awareness on this matter.

SILVER DIAMINE FLUORIDE - A REVIEW

Despite the fact that the prevalence and severity of dental caries in children has decreased in recent decades, children from low socioeconomic backgrounds continue to endure the consequences of dental caries in many developed and developing nations. The antibacterial action of silver compounds has been demonstrated through the use of silver compounds for the prevention and treatment of various infections for over a century. Though silver diamine fluoride (SDF) was used to prevent dental cavities in Japan throughout the 1970s, it was little known in the rest of the globe. A 38 percent (44,800 ppm fluoride) SDF solution is now widely used in several countries to prevent cavities and relieve hypersensitivity in primary and permanent teeth. SDF application to prevent dental cavities is a non-invasive, rapid, and uncomplicated technique. According to reports from published studies, SDF application did not cause serious pulpal damage. It does, however, have some disadvantages, such as black darkening of carious teeth and an unpleasant metallic taste. However, due to its low cost and ease of usage, SDF appears to be a good therapeutic agent for use in community dental health projects.

The Impact of Dental Hypersensitivity on the Patients Quality of Life. A Questionnaire-Based study

Introduction: Dentinal hypersensitivity is a pathological condition with an increased incidence among patients of various ages, affecting their well-being and with a common response for a wide range of treatment strategies.&#x0D; The study aimed to assess the impact of teeth hypersensitivity on the quality of life, daily activities, and on the emotional status of the patients affected by it.&#x0D; Method: We conducted an anonymous survey on a group of 200 patients with ages 20 and 65 years old, using a questionnaire that included 23 questions. The results were collected and statistically analyzed using the chi-square test.&#x0D; Results: Out of all the patients who answered our questionnaires, 51 percent have ages between 20-25 years, 26 percent between 26-35 years, 12 percent between 36-45 years, respectively 11 percent represent patients older than 46 years. 81 percent of patients are female, and 19 percent are male. In 65 percent, the onset of dental hypersensitivity sensations is caused by the consumption of ice cream, affecting the patients‘ lifestyle negatively. According to the study, 36 percent of patients give up on certain foods/drinks that led to the appearance of dentinal hypersensitivity sensations. Forty-one correspondents felt compelled to give up consuming cold food, and carbonated and sour drinks.&#x0D; Conclusions: Dentin hypersensitivity is represented by the appearance of an uncomfortable sensation due to dentin being exposed to the exterior environment, a sensation that can range from mild irritation to severe pain and can reduce the quality of mastication and oral hygiene.

The study of toothpaste desensitizing properties

Relevance. Over the past decade, manufacturers of oral care products have expanded the possibilities of solving the problem of hypersensitivity of teeth due to a variety of new modern technologies, which provides an opportunity to increase the effectiveness of active oral care product components. The study aimed to investigate desensitizing, remineralizing and anti-caries effectiveness of Asepta Extra Sensitive toothpaste to confirm the toothpaste properties stated by the manufacturer. Material and methods. Forty-nine people, aged from 24 to 58 years, participated in the clinical testing of the toothpaste. The study used the Orekhova – Ulitovskiy tooth sensitivity index to evaluate the desensitizing toothpaste and determined the severity of dental hyperesthesia using diagnostic tests. We objectively assessed the functional state of the enamel using the Okushko – Kosareva enamel resistance test. The study evaluated the electrical conductivity of the dentin hypersensitivity to investigate the anti-caries effect.Result. The desensitizing effectiveness increased to 64.59 ± 5.72% by the end of the study, according to the Orekhova – Ulitovskiy sensitivity index. The dentin hypersensitivity hypersensitivity decreased, according to the diagnostic tests. The tooth sensitivity reduction effectiveness increased – 62.22 ± 6.84%, according to the tooth tactile sensitivity assessment by linear advancement of the probe along the tooth surface. The analysis of the remineralizing parameter showed positive changes in the enamel resistance test. The remineralizing parameter value amounted to 21.49 ± 1.91%, and the remineralizing effectiveness reached 61.05 ± 2.98%. The values of anti-caries action and anti-caries effectiveness were 3.31 ± 0.52 mA and 29.72 ± 1.92%, respectively, according to the method of dentin hypersensitivity electrical conductivity evaluation with Asepta Extra Sensitive toothpaste. The desensitizing, remineralizing and anti-caries results of Asepta Extra Sensitive toothpaste use were high.Conclusion. The development of dental health strengthening measures determines the significance of oral care products in tooth sensitivity prevention in the population, which plays a leading role in planning individual programs to prevent major dental diseases.

CLINICAL AND EPIDEMIOLOGICAL MANIFESTATIONS OF DENTAL HYPERESTHESIA AMONG RESIDENTS OF VASILEOSTROVSKY DISTRICT OF ST. PETERSBURG

Abstract: The article aims to establish the prevalence and nature of dental hyperesthesia among residents of the Vasileostrovsky district of St. Petersburg. Increased tooth sensitivity is of great interest in the practice of a dentist due to its high prevalence and polyetiological nature. The study involved 126 people of both sexes, divided into 3 age groups (19-29; 30-44; 45-63). It was revealed that 97 of them had hypersensitivity of teeth at the moment of examination. In addition to establishing the presence of the pathology under study and counting the affected teeth, the following dental indices were used to objectify the evaluation: 1. Hygienic index -HI (simplified Green-Vermillion index OHI-S (Green, Vermillion, 1964)) - used to determine the level of oral hygiene. 2. Parodontal index-PI (P.A. Leus, 1988) - to determine the presence of symptoms of periodontal pathology. 3. Intensity of dental caries lesion was determined using the index of DMF (Klein, Palmer, 1937). 4. Assessment of dental hyperesthesia was carried out using the index of prevalence and intensity of dental hyperesthesia (G.B. Shtorina, 1986). All patients responded to the Oral Health Impact Profile (OHIP-14)-to determine the impact of hyperesthesia on quality of their life. Each tooth was checked for carious and non-carious defects to determine the most frequent causes of tooth hypersensitivity. Based on our study the following conclusions were made: 1. Among all detected cases, women aged 31 to 45 years (22.680%) were most susceptible to hyperesthesia. Less susceptible to hypersensitivity of teeth are men aged 46-63 years and older (10.309%). 2. Patients with hyperaesthesia were more likely to have poor oral hygiene (OHI-S- 1.7483 points), moderate periodontal disease (PI-2.1316 points) and high caries intensity (DMF-16.2166 points). 3. Limited form of dental hyperesthesia (66.585%) is more frequent among women aged 31-45 years (17.191%) and men aged 31-45 years (14.769%). 4. The generalized form is more frequent among women 46-63 years (8.475%) and men 46-63 years (7.748%), less frequent among women 19-30 years (2.663%). 5. Sensitivity only to temperature stimuli was registered in 47,699% of cases - more frequent among women 31-46 years (16,496%) pain during exposure to temperature and chemical stimuli - 9,685% of cases (women 31-45 years - 3,148%) and reaction to all types of stimuli was registered in 42,615% of cases (more frequent among women 31-45 years - 14,286%). 6. Of all identified teeth with hypersensitivity (413 teeth examined), wedge-shaped defect was more frequent among women 31-45 years old, and gingival recession among men in two age groups 31-45 and 46-63. 7. Patients in age group 1, 19-30, are more likely to have chips and microcracks that can cause tooth sensitivity. 8. Patients were noted to a decrease in their quality of life due to hyperesthesia and related diseases.

Comparative study on the efficacy of OliNano Seal and Curodont D’Senz in the treatment of dentin hypersensitivity (clinical trial and in vitro study)

ABSTRACTPurpose:The present study was carried out to assess and compare the efficacy of OliNano Seal (OS) and Curodont D’Senz (CS) in the treatment of dentin hypersensitivity (DH) and the reduction of dentin permeability.Materials and Methods:The current study was a single-blinded, clinical trial and in vitro study using OS and CS in the treatment of DH. A total of 72 hypersensitive teeth were selected from 18 patients and randomly divided into two groups. Prior to the desensitizing agent’s application (the baseline), as well as immediately, 2 weeks, 4 weeks, and 3 months afterward, the evaluated materials were applied. Patients were instructed to use the visual analogue scale (VAS) to score their perception of tactile, air, and cold stimuli (VAS). In total, 90 samples were used for the evaluation, and they were randomly divided into two main groups: group A1, which had the smear layer fully removed, and group A2, which had the smear layer partially removed. According to the desensitizing agent used, each group was divided into three subgroups: OS, CS, and the control group that was left untreated. The results of the dentin permeability test were analyzed using the analysis of variance test, whereas the pain scores were analyzed using the Mann–Whitney test.Results:The study showed that there was a high statistically significant difference between pain scores prior to and after the application of both tested desensitizing agents. Permeability results revealed a high statistically significant difference between the study groups, with the lowest statistically significant mean depth of dye penetration found with OS-treated samples.Conclusion:OS and CS were both effective in the treatment of DH and the reduction of dentin permeability, with OS being more effective within 1 week and sustained up to 3 months.

Dentists' knowledge, attitudes, and professional behavior regarding silver diamine fluoride: A cross-sectional questionnaire study

Background: Dental caries is a major public health problem and is handled through either treatment or prevention. Unlike other fluoride-based caries preventive agents, silver diamine fluoride (SDF) can simultaneously prevent and arrest coronal and root dentine caries. Aim: The aim of this study is to assess dentists' educational experiences, knowledge, attitudes, and professional behavior regarding SDF use for caries prevention. Methodology: For the cross-sectional survey, a prevalidated questionnaire comprising of 33 questions was being prepared through the Google survey tool of Gmail and was sent to 200 dentists in North India region through Whatsapp groups of different communities or specialties. Data analysis was done using IBM SPSS version 16. Results: The response rate of 63.5% was received from 200 dentists, among which 28.8% were general practitioners and 35.2% were both academic and clinical practitioners. Only 5.6% respondents came up having been very well educated about SDF during Bachelors in Dental Surgery and Master of Dental Surgery in the classroom setting and 3.2% in the clinical setting. There were 14.4% participants who reported that they knew very well about what SDF is used for in dentistry, and 9.6% knew how SDF is used for treatment of tooth hypersensitivity, 24.8% knew how SDF is used to treat dental caries. The attitudes of the dentists toward SDF were positive. SDF use was considered a good treatment alternative for restorations in children with behavioral problems (17.6%), for patients who were medically fragile (12%) or had severe dental anxiety (19%) and strongly agreed to it. Conclusion: Results suggested that the majority of respondents were lacking in knowledge regarding usage of SDF in dentistry.

Clinical Evaluation of Lateral Pedicle Flap Stabilized with Cyanoacrylate Tissue Adhesive: A Randomized Controlled Clinical Trial.

Context:Gingival recession is the most common mucogingival defect and is susceptible to tooth hypersensitivity, root caries, and esthetic problems if left untreated. A lateral pedicle flap is used to cover denuded roots that have adequate donor tissue laterally and adequate vestibular depth. A carefully planned surgery needs proper immobilization of the flap at the recipient site and this can be achieved by proper wound closure technique with appropriate material such as sutures or tissue adhesives.Aim:The aim of the present study is to evaluate the clinical outcomes of lateral pedicle flap stabilized with cyanoacrylate tissue adhesive and resorbable sutures.Materials and Methods:Twenty-two patients with Miller's class I and class II gingival recession were randomly divided into two groups: lateral pedicle flap stabilized with cyanoacrylate tissue adhesive (test) and lateral pedicle flap stabilized with resorbable sutures (control). Plaque index, gingival index, probing pocket depth, clinical attachment level, recession depth and width, height and thickness of keratinized gingiva were evaluated at baseline and 1st and 3rd month postoperatively. The percentage of root coverage was evaluated at the end of 3rd month postoperatively.Statistical Analysis Used:Intergroup comparisons for the clinical attachment level, recession depth, recession width, thickness of keratinized gingiva, and height of keratinized gingiva were made by Mann–Whitney test by analyzing the difference of two time periods. Intragroup comparisons were made by the Kruskal–Wallis test. Mann–Whitney test was used to compare the difference between various time periods within the group for all the selected variables.Results:The mean plaque index and gingival index at the 1st and 3rd month were found to be statistically significant and did not present any significant influence over other clinical parameters evaluated. A partial root coverage was observed in both the groups (71.97% for the test group and 61.36% for the control group).Conclusions:Cyanoacrylate tissue adhesive is clinically effective in the stabilization of the lateral pedicle flap and can be used as an alternative to resorbable sutures.

Etiology and Management of Hypersensitivity of Teeth - A Review

Hypersensitivity of teeth is a common clinical condition usually associated with exposed dentinal tubules. It is predominantly found in patients belonging to 20-60 years of age and most commonly affects the canines and premolars of both the arches. This article concisely reviews the etiology, patho-physiology, mechanism and management of dentin hypersensitivity. Treatment of dentin hypersensitivity should start with an accurate diagnosis and removal of the etiology. Differential diagnosis should be made and all other probable causes should be excluded. An often neglected phase of clinical management of dentin hypersensitivity is the identification and treatment of the causative factors. By removing the etiological factors, the condition can be even prevented from occurring or recurring. There are various treatment modalities available which can be used at home or may be professionally applied. The “at home” desensitizing agents include toothpastes, mouthwashes or chewing gums and they act by either occluding the dentinal tubules or blocking the neural transmission. The in-office treatments include application of potassium nitrate, fluorides, adhesive resins, copal varnish and oxalates. This article also discusses the recent treatment options like carbonated nano hydroxyapatite crystals bioglass, calcium silicate derivative of Portland cement, lasers and casein phosphopeptide.
