Comparison of Carisolv system vs traditional rotating instruments for caries removal in the primary dentition: A systematic review and meta-analysis

Evaluation of the Erbium-doped Yttrium Aluminum Garnet Laser and the Conventional Method on Pain Perception and Anxiety Level in Children during Caries Removal: A Randomized Split-mouth Study

Aim and objective

To assess and compare children's anxiety level and pain perception during cavity preparation using an erbium-doped yttrium aluminum garnet (Er:YAG) laser vs traditional rotational treatment.

Materials and methods

A randomized, controlled, split-mouth clinical trial was carried out in 35 healthy children with 70 carious primary molars. Teeth were divided equally into two groups according to the method of treatment. A bur was used to prepare the cavity in one quadrant, while an Er:YAG laser was used to prepare the cavity in the other quadrant. Anxiety was assessed using Venham's dental anxiety scale and a fingertip pulse oximeter. The pain was assessed using the Wong-Baker Face Pain Rating Scale, and the number of local anesthesia (LA) needed during both procedures was also considered.

Results

The mean age was 9.4 ± 1.29. Males accounted for 51.4% of the participants. There were no statistically significant variations in pulse rate at the baseline between Er:YAG laser and the conventional treatments. The mean pulse rate was higher during the conventional intervention than during the laser intervention; this difference was statistically significant vs the baseline pulse rate. The mean pulse rate with the conventional method was significantly higher during and after cavity formation than with the laser method. The Er:YAG laser and the conventional groups showed statistically significant differences in the Venham's and Wong-Baker scores. The scores of both scales were much higher in the conventional group. The number of participants who requested LA during the conventional technique was significantly higher than during the laser procedure.

Conclusion

Using Er:YAG lasers to remove caries produces minimal pain and anxiety and reduces the requirement for LA.

Clinical significance

During cavity preparation, the Er:YAG laser helps children stay calm.

Chemomechanical Caries Removal Methods: A Literature Review

Aim

To provide dental practitioners and researchers with a comprehensive review of the historical development, chemical composition, mechanisms of action, advantages, and drawbacks of different chemomechanical caries removal (CMCR) agents.

Methods

An electronic search was performed for all articles published on CMCR agents in various databases, including the Web of Science, PubMed, Cochrane, Scopus, and Google Scholar bibliographic databases, from January 1, 1975, to July 31, 2022.

Results

Records were identified using the following search terms: Brix3000, Carie-Care, Caridex, Carisolv, chemomechanical caries removal, conventional surgical method, and Papacárie. A total of 171 articles were screened based on the titles and abstracts, of which 126 were deemed eligible for inclusion after duplicates were removed. Following a manual search of the reference list, eight articles were added. Articles were then excluded for other reasons, such as being written before 1975, being written in a language other than English, and the non-availability of the full text. Overall, 120 articles were included in the analysis (literature reviews [n = 27], systematic reviews [n = 8], research articles [n = 82], case reports [n = 3]).

Conclusion

CMCR is a potential method of caries control in the future as an alternative to the conventional surgical approach in standard dentistry applications. It is more widely accepted, less painful, and has comparable efficacy to the conventional surgical method.

Clinical significance

A continuous trend among manufacturers has been observed since 1975 to reduce the drawbacks of CMCR agents. Moreover, evidence-based minimally invasive techniques, including CMCR agents that require minimal or no aerosol-generating procedures, are preferred while measures to control the spread of coronavirus disease are in force.

A Bibliometric Analysis (2010-2020) of the Dental Scientific Literature on Chemo-Mechanical Methods of Caries Removal Using Carisolv and BRIX3000

Reports in the literature have proposed and analyzed several minimally invasive techniques for caries removal in recent decades. In light of recent events surrounding the ongoing epidemiological context, concerns have been raised regarding the generation of aerosols during dental procedures. The aim of our research was to provide an overview of the scientific literature on the topic of chemo-mechanical caries removal (CMCR) methods, focusing on two products (Carisolv, BRIX3000), commercially available in Europe. A bibliometric analysis was used to investigate the scientific articles included in Web of Science (WoS) Core Collection database, published from January 2010 to December 2020. We analyzed the co-occurrence of all keywords (Author Keywords and the KeyWords Plus section), co-authorship and co-citation, using the free software VOSviewer. Our bibliometric analysis revealed a worldwide interest in the subject of chemo-mechanical methods of caries removal, which has transcended the area of pediatric dentistry. The analyzed studies have been conducted mainly in high-income countries that have developed sanitary policies regarding prevention and early treatment of carious lesions as a health priority.

Worldwide research trends on the use of chemical-mechanical caries removal products over the years: a critical review

BACKGROUND

Chemical-mechanical caries removal (CMCR) products are in constant evolution and were recommended during the COVID-19 pandemic as substitutes for conventional caries removal.

AIM

Characterize the worldwide scientific literature about CMCR products, over the years, by means of a critical review.

DESIGN

Electronic search was performed on Medline/PubMed, Scopus, Web of Science, Cochrane Library, Lilacs, and Embase up to November 2020. Year, journal, country of authors, and type of study were the data extracted from the retrieved studies. Additional data of the clinical studies and systematic reviews were investigated.

RESULTS

2221 records were identified, 397 selected. 2011-2020 period concentrates higher number of publications (n = 169), in the Journal of Dental Research (n = 51), developed in Brazil (n = 45) and India (n = 44). Most studies were in vitro (n = 211) and clinical trials (n = 101). Carisolv™ (n = 48) and Papacarie Duo Gel™ (n = 33) were the most used products, prescript in isolated usage (n = 101), and compared with drills (n = 77). CMCR were more studied in primary teeth (n = 78), receiving glass ionomer cement (GIC) (n = 51) as restorative material. The most evaluated outcomes were time spent (n = 48) and pain (n = 41). Clinical application of CMCR takes more time than other techniques, but can also reduce patient anxiety, pain, and need for anesthesia.

CONCLUSION

In vitro and clinical studies with CMCR products have been increasing, mostly carried out in developing countries, evaluating Carisolv™ and Papacarie Duo Gel™. Clinical studies tend to evaluate the time spent and pain compared to drills for removing caries in primary teeth, posteriorly restored with GIC. CMCR clinical application reduces anxiety, pain, and need for anesthesia, despite increase treatments' time.

Model for Taking Care of Patients with Early Childhood Caries during the SARS-Cov-2 Pandemic

Pending the availability of vaccines to contain the SARS-CoV-2 pandemic, the current solution is "social distancing" with a reduction of dental treatments to those assessed as urgent and emergency cases. These treatments also involve Early Childhood Caries (ECC) due to the fact that this disease affects preschool children (a vulnerable population) and, in addition, shows a propensity to evolve into more serious complications (dental pain, infections). A narrative review was carried out to support a protocol for treating ECC with efficacious and safe (in terms of SARS-CoV-2 transmission) procedures. Protocol involves criteria for patients' selection remotely (telemedicine), and well-detailed criteria/equipment and hygiene procedures to combat against SARS-CoV-2 transmission. Moreover, the protocol proposes innovative caries treatments, named Minimally Invasive Treatments (MITs), well known in pedodontics for their high level of children's acceptance during dental care. MITs allow for caries removal (particularly in primary teeth) without any high-speed rotating instrument cooled with nebulized air-water spray (with high risk of virus environmental diffusion), usually adopted during traditional treatments. For evaluating MITs effectiveness in caries management, only Systematic Review and Randomized Controlled Trials (RCTs) were included in our study, without any risk of bias assessment. The indications proposed in this protocol could support clinicians for the temporary management of ECC until the SARS-CoV-2 pandemic ends.

Factors associated with the publication outcomes of paediatric proceedings presented at 2010-2016 the International Associations for Dental Research annual meetings

The International Associations for Dental Research (IADR) annual meeting is one of the most important dental meetings throughout the world, and researches about paediatric dentistry presented in this platform are often used to guide clinical work. To evaluate the publication outcomes of oral and poster paediatric proceedings, which were accepted by the International Associations for Dental Research (IADR), annual meetings from 2010 to 2016 and to analyse the possible factors influencing an abstract's progression to publication. Oral and poster abstracts were retrieved from the official website of IADR (2010-2016). Searching for subsequent publications was conducted in PubMed and Google Scholar (up to March 2019). Two authors independently selected studies, collected, and analysed data. A total of 1396 abstracts were identified, including 275 oral presentations and 1121 poster presentations. Finally, 606 were published in peer-reviewed journals, with a publication rate of 43.41%. Abstracts were published earlier if it is from Europe, well funded, presented orally, or with large sample size. The high publication rate of the IADR proceedings supported the impact of IADR annual meetings on paediatric dentistry in the last 10 years.

Efficacy and Efficiency of Papacarie versus Conventional Method in Caries Removal in Primary Teeth: An SEM Study

Background

Chemomechanical methods such as Papacarie were developed as alternate dental caries removal methods to overcome major disadvantages of the conventional drilling technique. However, few studies have demonstrated the efficacy of Papacarie for caries removal using scanning electron microscope (SEM).

Objectives

The purpose of this study was to compare the efficacy and efficiency of Papacarie and the conventional bur method in caries removal from primary teeth.

Materials and Methods

In this in vitro study, 30 freshly extracted, human primary molars with dentinal caries were obtained from the outpatient clinics at the Dental Hospital of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Each tooth was sectioned mesiodistally into two halves through the center of the lesion, and each half was randomly subjected to caries removal by Papacarie (Group I) and excavation using the conventional bur method (Group II). Time taken (efficiency) for removal of caries was noted using a stopwatch. Samples were then examined under SEM for presence of bacterial colonies (efficacy). For efficiency, data were analyzed using chi-square, and for efficacy, using t-test.

Results

There was no significant difference in the presence of bacteria in both groups under SEM (Papacarie = 23.3%; conventional method = 16.7%; P = 0.52). However, significantly more time was taken for caries removal with Papacarie (mean = 351.56 s) than with the conventional bur method (mean = 158.41 s) (P < 0.0001).

Conclusion

Papacarie is as effective in removing dentinal bacteria as the conventional caries removal method but is less efficient, as the time taken for excavation was longer.

Atraumatic Restorative Treatment and Interim Therapeutic Restoration: A Review of the Literature

This review discusses the techniques and uses of atraumatic restorative treatment (ART) and interim therapeutic restoration (ITR) and states the differences between these two approaches. ART and ITR are similar approaches and are performed using the same material, but they differ in the purpose of their use. ART is used in cases when there are obstacles to reaching dental care units and has been proven to have high success rates in primary and permanent dentitions. ITR is used as a temporary restoration that will be replaced with a more definitive one. ITR is used in cases when the ideal dental treatment cannot be performed. Conventional glass polyalkenoate (ionomer) restorative cement (GIC) is the material of choice that has been used for ART and ITR. This is because of its fluoride release properties, including its ability to bond to enamel and dentine, its pulpal biocompatibility, and its ease of manipulation. High-viscosity glass ionomer performed better than low and medium-viscosity glass ionomer in ART. Combining GIC with conditioner, as well as the use of a chemo-mechanical approach, improved the success rate of ART. Both ATR and ITR are acceptable strategies, with success rates comparable to the traditional treatment methods.

New treatment method for pain and reduction of local anesthesia use in deep caries

Chemo-mechanical caries removal methods are known to be more effective compared with conventional methods in pain reduction. Carie-care™, a chemo-mechanical caries removal agent, was introduced in 2010 but a systematic review of its efficacy has not yet been performed. The purpose of this study was to investigate the effectiveness of Carie-care™ on the outcomes of treatment of caries in children and adolescents. The primary outcome was pain while the secondary outcomes included complete caries removal (CCR), time, need for local anesthesia and behavioral response changes.

A Comprehensive literature search was performed in PubMed, EMBASE, and the Cochrane Library up to 30 September 2018. The following keywords were used in the search: ‘chemo-mechanical caries removal agent’, ‘dental caries’, ‘Carie-care’, ‘chemo-mechanical caries removal’, ‘chemo-mechanical caries excavation’, other related keywords, and their combinations. From 942 studies identified, 16 were analyzed. Finally, 4 studies met the eligibility criteria and 260 teeth in 120 children and adolescents were included in this review.

This review showed that Carie-care™ reduces pain during caries treatment but requires a longer time for effective treatment than conventional methods. Local anesthesia was not required in the Chemo-mechanical caries removal (CMCR) group. In addition, dental anxiety decreased compared to the control group, and co-operation was more positive. Therefore, it may be a useful alternative to conventional methods in children and adolescents, but further verification through additional studies is needed.

A Randomized Controlled Trial Comparing Er:YAG Laser and Rotary Bur in the Excavation of Caries - Patients' Experiences and the Quality of Composite Restoration

Objective

The aim of this study was to evaluate patients´ experiences of two excavation methods, Er:YAG laser and rotary bur and time required by the methods as well as objective assessments of quality and durability of restorations over a two-year period.

Methods

A prospective, single-blind, randomized and controlled investigation was performed. Patients aged 15 to 40 years with at least two primary caries lesions, which had been radiographically assessed as of the same size, were recruited. In each patient, one cavity was excavated using rotary bur and one using Er:YAG laser technique. The time required for excavations and, where applicable, local anaesthesia, was measured during the treatments. Patient experiences were measured using questionnaires. The quality and durability of restorations were assessed over a two-year period in accordance with modified Ryges criteria and radiographs. Twenty-five patients (mean age 22.6 years) participated in the study. In total, 56 cavities were included of which 28 were treated with Er:YAG laser and 28 were treated with a rotary bur.

Results

The patients associated the laser method with less discomfort. The mean time for excavation by laser was three times longer than by rotary bur (13.2 min vs. 4.3 min, P<0.0001). Over a two-year period, no statistically significant differences with regard to quality or durability could be seen between the restorations associated with the methods.

Conclusion

The Er:YAG laser technique was more time-consuming than the rotary bur. Despite this, the laser technique caused less discomfort and was preferred as an excavation method by patients.

Annual review of selected scientific literature: Report of the committee on scientific investigation of the American Academy of Restorative Dentistry

STATEMENT OF PROBLEM

It is clear the contemporary dentist is confronted with a blizzard of information regarding materials and techniques from journal articles, advertisements, newsletters, the internet, and continuing education events. While some of that information is sound and helpful, much of it is misleading at best.

PURPOSE

This review identifies and discusses the most important scientific findings regarding outcomes of dental treatment to assist the practitioner in making evidence-based choices. This review was conducted to assist the busy dentist in keeping abreast of the latest scientific information regarding the clinical practice of dentistry.

MATERIAL AND METHODS

Each of the authors, who are considered experts in their disciplines, was asked to peruse the scientific literature published in 2015 in their discipline and review the articles for important information that may have an impact on treatment decisions. Comments on experimental methodology, statistical evaluation, and overall validity of the conclusions are included in many of the reviews.

RESULTS

The reviews are not meant to stand alone but are intended to inform the interested reader about what has been discovered in the past year. The readers are then invited to go to the source if they wish more detail.

CONCLUSIONS

Analysis of the scientific literature published in 2015 is divided into 7 sections, dental materials, periodontics, prosthodontics, occlusion and temporomandibular disorders, sleep-disordered breathing, cariology, and implant dentistry.

Microindentation hardness and calcium/phosphorus ratio of dentin following excavation of dental caries lesions with different techniques

BACKGROUND

The aim of this in vitro study was to evaluate the microindentation hardness and chemical composition of residual dentin left at the cavity bottom following removal of carious dentin using the Carisolv chemomechanical and Er:YAG laser caries excavation methods in comparison with the conventional tungsten-carbide bur excavation.

METHODS

Sixty-nine extracted permanent teeth with occlusal dentin caries were assigned into three groups according to caries removal technique. Carious dentin excavation was guided by tactile method and a caries-staining dye. In stereomicroscope images (100×) of the samples, the presence or absence of residual caries was defined. The Knoop hardness value of the cavity floor was determined and atomic analysis of treated cavities was performed by energy dispersive X-ray spectroscopy.

RESULTS

The Knoop hardness value of residual dentin left at the cavity bottom was lower (One-way ANOVA, Dunnett-C, p < 0.05) and the percentage of samples with remaining carious dentin was higher after Carisolv excavation than those obtained after conventional and laser excavations (Kruskal-Wallis, Mann-Whitney U, p < 0.05). No significant differences were found between the quantities of calcium content (Ca wt%), phosphorus content (P wt%) and calcium/phosphorus ratio of the cavities treated by three techniques (Kruskal-Wallis, Mann-Whitney U, p > 0.05).

CONCLUSION

The results indicated that Er:YAG laser was more comparable to conventional bur excavation than chemomechanical method in the efficacy of caries removal with regard to microindentation hardness of remaining dentin and both Carisolv gel and Er:YAG laser did not alter chemical composition of residual dentin in the treated cavities.
