Abstract
Conservative caries removal has become an integral part of minimally invasive dentistry (MID). Polymer and Cera burs are two feasible MID methods. The aim of the study was to compare the efficiency of Polymer, Cera, and Tungsten carbide bur in dentin caries excavation of mandibular primary molars. 45 children in the age group of 6-8 years with dentin caries, not involving pulp in the second mandibular primary molars, were selected for the study. The three burs compared were polymer bur, Cera bur, and Tungsten Carbide bur. The excavation of carious lesion was performed with each burs using a slow-speed handpiece with 500-1000rpm. Caries removal efficiency was evaluated using the Visual-Tactile method and confirmed Dye detection method. The time taken to complete the caries removal was measured using a stopwatch. The patient's pain perception was assessed using the Wong-Baker Faces Pain Rating Scale. The intergroup comparisons based on time, dye, and Wong-Baker Faces Pain Rating Scale (WBFPRS) were arrived at using Mann-Whitney and Fisher Exact tests at P < 0.0001. A statistical significance between the three groups on the time taken for caries removal at P < 0.0001. No statistical significance was observed between the three groups for caries removal efficiency and pain perception using the dye and WBFPRS scores at P > 0.001. Cera burs had shown high caries removal efficiency, which had taken less time in the excavation, with reduced pain perception followed by Tungsten Carbide bur and the polymer bur in mandibular primary molars.

Abstract
To evaluate the efficiency and effectiveness of three minimally invasive (MI) techniques in removing deep dentin carious lesions. Forty extracted carious molars were treated by conventional rotary excavation (control), chemomechanical caries removal agent (Brix 3000), ultrasonic abrasion (WOODPECKER, GUILIN, China); and Er, Cr: YSGG laser ablation (BIOLASE San Clemente, CA, USA). The assessments include; the excavation time, DIAGNOdent pen, Raman spectroscopy, Vickers microhardness, and scanning electron microscope combined with energy dispersive X-ray spectroscopy (SEM-EDX). The rotary method recorded the shortest excavation time (p < 0.001), Brix 3000 gel was the slowest. DIAGNOdent pen values ranged between 14 and 18 in the remaining dentin and laser-ablated surfaces recorded the lowest reading (p < 0.001). The Ca:P ratios of the remaining dentin were close to sound dentin after all excavation methods; however, it was higher in the ultrasonic technique (p < 0.05). The bur-excavated dentin showed higher phosphate and lower matrix contents with higher tissue hardness that was comparable to sound dentin indicating the non-selectiveness of this technique in removing the potentially repairable dentin tissue. In contrast, the MI techniques exhibited lower phosphate and higher organic contents associated with lower microhardness in the deeper dentin layers. This was associated with smooth residual dentin without smearing and patent dentinal tubules. This study supports the efficiency of using MI methods in caries removal as conservative alternatives to rotary excavation, providing a promising strategy for the clinical dental practice.

Abstract
BACKGROUND Chemomechanical techniques for caries removal have been introduced to overcome the shortcomings of the conventional rotatory instruments. This study aimed to clinically evaluate the effectiveness of the chemomechanical method of caries removal (Carie-Care™) over mechanical caries removal through the Atraumatic Restorative Technique in pediatric patients. METHODS A randomized controlled clinical trial was conducted. Fifty children fulfilling inclusion criteria were recruited from the outpatient clinic of Pediatric and Dental Public health department, Faculty of Dentistry, Alexandria University. Fifty open carious primary molars were randomly assigned into 2 equal groups according to the method of caries removal. In Group I (test group), caries was removed using the Carie-Care™ system and in Group II (control group), by using mechanical caries removal through the atraumatic restorative technique. Resin modified glass ionomer was used for teeth restoration, the two techniques were compared in each child according to time taken for caries removal, efficacy of caries removal, pain assessment, and child behavior. RESULTS The mean time taken for caries removal in the Carie-Care™ treatment group was (575.6 ± 114.8) seconds which was statistically significant higher as compared with the ART treatment group (346.1 ± 97.4) seconds (p < 0.001). The mean score of efficacy in caries removal was (0.6 ± 0.8) in the Carie-Care™ group, and (1.3 ± 0.7) in the ART treatment group. When compared to ART, Carie-Care™ was significantly more efficient in caries removal (p < 0.002). When pain was assessed by the SEM scale, it was observed that the Carie-Care™ caries removal technique showed statistically significantly more comfort during the procedure compared with the ART procedure (p < 0.001).Moreover, children in the Carie-Care™ group enjoyed the process and showed more cooperative behavior when assessed at the end of procedure than those in the ART group with statistically significant difference (p = 0.002). CONCLUSIONS Removal of carious tissue in primary teeth using Chemomechanical Carie-Care™ gel proved to be more time consuming than ART, but on the other hand it was more efficient, comfortable, and accepted by the pediatric patients.

Subjective versus objective, polymer bur-based selective carious tissue removal: 2-year randomized clinical trial. J Dent 2023; 138:104728. [PMID: 37783372 DOI: 10.1016/j.jdent.2023.104728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/25/2023] [Accepted: 09/26/2023] [Indexed: 10/04/2023] Open
Abstract
OBJECTIVES We aimed to compare subjective (S) selective carious tissue removal using hand instruments versus objective (O) removal using a self-limiting polymer bur in a single-blind cluster-randomized controlled superiority trial. METHODS 115 children (aged 7-8 years) with ≥1 vital primary molar with a deep dentin lesion (>1/2 dentin depth) were included and randomized (60 S/55 O); all eligible molars in a child were treated identically (91 S/86 O). Cavities were prepared and carious tissue on pulpal walls selectively removed using hand instruments (S) or a self-limiting polymer bur (Polybur P1, Komet), followed by restoration using a glass hybrid material (Equia Forte, GC). Treatment time and satisfaction data have been reported in a 1-year-interim report. We here report on 2 year survival (tooth retained with or without further retreatments being needed, or tooth exfoliated), analyzed using multi-level Cox-regression analysis, as well as success (ART criteria 0/1, no pulpal complications, no re-intervention needed, or tooth extraction). RESULTS 71 restorations in S and 65 in O were examined after a mean (SD, range) of 22 (11; 3-31) months, of which 50 S and 48 O restorations were successful and 70 S and 65 O survived. The majority of failures were restorative, not pulpal, and distribution of ART codes was not significant different between groups. Risk of failure was not significantly associated with the removal protocol (HR; 95 % CI: 0.95; 0.51-1.78), and also not age, sex or dental arch, while single surfaced restorations showed significantly lower hazard (0.14; 0.06-0.37). CONCLUSION There was no significant difference in success or survival between objective and subjective carious tissue removal. CLINICAL SIGNIFICANCE In primary teeth, subjective selective excavation had no disadvantage compared with objective excavation, which required a separate instrument (polymer-based bur) for carious tissue removal. Polymer-based burs may be particularly useful when standardized excavation is needed.

Chemomechanical Caries Removal Methods: A Literature Review. Saudi Dent J 2023; 35:233-243. [PMID: 37091279 PMCID: PMC10114597 DOI: 10.1016/j.sdentj.2023.01.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/08/2023] Open
Abstract
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.

Abstract
Conventional method for removal of carious tissue using low speed drills usually induce noise and vibration, in addition to thermal and pressure effects that can be harmful to the pulp tissue and cause fear in children. Therefore, several alternative methods are being developed to try to minimize the unpleasant perception of the patient during caries removal. Chemical-mechanical removal of carious tissue goal is to selectively remove the carious lesion, which reduces the amount of bacteria inside the cavity without removing the tissue susceptible to remineralization. This method is also able to minimize the tactile perception by the patient during the manipulation of the lesion compared to the conventional method, and, therefore, it has been widely accepted among phobic patients, children and special needs patients. Due to the close relationship between dentin and pulp tissue, all injuries imposed on this dentin may have repercussions on the underlying pulp connective tissue. The morphological aspects of remaining dentin favor the diffusion of chemical components of dental materials, which can be toxic to the pulp tissue or even negatively interfere in the reparative process. Thus, considering the proximity between the applied material and the underlying pulp tissue, especially in deep cavities, there is a need to assess the biological behavior of dental materials against pulp cells, since aggressions to the pulp tissue can be caused not only by metabolites from microorganisms involved in dental caries but also by components that are released from these products. This subject was explored in this narrative literature review.

Abstract
Aim and objective To assess the efficacy of the new Carisolv system and Polymer bur (SmartbursII®) for selective caries removal in primary molars clinically and microbiologically, compared with the conventional mechanical method. Materials and methods Sixty children with class I active carious lesions were selected. The children were randomly allocated to three groups (n = 20) according to the caries removal method. Under rubber dam isolation, dentin samples were taken before and after caries removal for microbial culture. Time spent in each technique was recorded. The clinical efficacy of caries removal was verified using caries detector dye. Patient satisfaction toward the treatment was evaluated using a facial image scale. Results The median of caries detector dye scores was significantly lower in the conventional group compared to others (p value < 0.05). The mean time for caries removal was the longest with Carisolv (p value < 0.05). The median of facial image scale scores was significantly higher in the conventional group compared with others (p value < 0.05). The mean total viable bacterial count after caries removal was significantly higher in polymer bur group compared with others (p value < 0.05). While, there was no significant difference between Carisolv and conventional groups (p value > 0.05). Conclusion The clinical efficacy of caries removal was highest with the mechanical method. Carisolv took the longest time for caries removal. Patient satisfaction was higher with Carisolv and polymer bur than the mechanical method. The antimicrobial efficacy of Carisolv and the mechanical method was higher than the polymer bur. Clinical significance Carisolv is a viable alternative to the mechanical method in the management of dental caries, especially in children. Further studies are needed to assess the efficacy of caries removal by SmartbursII®. How to cite this article Asal MA, Abdellatif AM, Hammouda HE.

Abstract
Dental caries is a disease of dental hard tissues, considered the most common non-communicable disease worldwide. Conventional treatments for caries removal are often associated with pain and fear, so different therapeutic approaches have been developed towards more conservative and pleasant treatments. This systematic review aimed to assess the efficacy and patient's acceptance of alternative methods for caries removal compared to conventional methods. The Cochrane Library, Embase, Medline/Pubmed, Web of Science, and Clinical Trials databases were searched. Clinical trials of primary dental caries treated with alternative methods were included. The last search was performed on 5 August 2020. The Population, Intervention, Comparison, and Outcome (PICO) strategy was followed. Thirty-seven clinical trials were included, reporting caries removal using alternative (chemomechanical-Brix 3000, Carie-care, Carisolv and Papacarie, laser-Er:YAG (Erbium-doped Yttrium Aluminium Garnet) and Er,Cr:YSGG (Erbium, Chromium-doped Yttrium, Scandium, Gallium and Garnet), and a system combining air and sono-abrasion-Vector® System) and conventional methods. Alternative methods tended to prolong treatment time and lessen anesthesia need. All treatments were effective in reducing cariogenic flora, and the restoration's performance did not differ significantly. Chemomechanical solutions seemed to be the best option towards minimally invasive treatments, with good control during application and action and good treatment experiences for patients. Papacarie was demonstrated to be an effective method for caries removal with less pain, and superior acceptance by patients when compared to conventional treatments.

Abstract
We aimed to compare subjective (S) vs. objective (O) selective carious tissue removal using hand-excavation versus a self-limiting polymer bur, respectively. A community-based single-blind cluster-randomized controlled superiority trial was performed. This is a 1-year-interim analysis. 115 children (age 7-8 years) with ≥1 vital primary molar with a deep dentin lesion (>1/2 dentin depth) were included (60 S/55 O). The cluster was the child, with eligible molars being treated identically (91 S/86 O). Cavities were prepared and carious tissue on pulpo-proximal walls selectively removed using hand instruments (S), or a self-limiting polymer bur (Polybur P1, Komet). Cavities were restored using glass-hybrid material (Equia Forte, GC). Treatment times and children's satisfaction were recorded. Generalized-linear models (GLM) and multi-level Cox-regression analysis were applied. Initial treatment times were not significantly different between protocols (mean; 95%CI S: 433; 404-462 sec; O: 412; 382-441 sec; p = 0.378/GLM). There was no significant difference in patients' satisfaction (p = 0.164). No pulpal exposures occurred. 113 children were re-examined. Failures occurred in 22/84 O-molars (26.2%) and 26/90 S-molars (28.9%). Pulpal complications occurred in 5(6%) O and 2(2.2%) S molars, respectively. Risk of failure was not significantly associated with the removal protocol, age, sex, dental arch or tooth type (p > 0.05/Cox), but was nearly 5-times higher in multi-surface than single-surface restorations (HR: 4.60; 95% CI: 1.70-12.4). Within the limitations of this interim analysis, there was no significant difference in treatment time, satisfaction and risk of failure between O and S.

Abstract
BACKGROUND AND OBJECTIVE Streptococcus mutans is the primary initiator and most common organism associated with dental caries. Prediction of post-Streptococcus mutans favours in the selection of appropriate caries excavation method which eventually results in meliorate caries-free cavity preparation for restoration. The objective of this study is to predict the post-Streptococcus mutans prior to dental caries excavation based on pre- Streptococcus mutans using iOS App developed on Artificial Neural Network (ANN) model. METHODS For the current research work, children with occlusal dentinal caries lesion were chosen, 45 primary molar teeth cases were studied. Caries excavation was done with carbide bur, polymer bur and spoon excavator. The colony forming units for pre and post-Streptococcus mutans were recorded, data emanating from clinical trials was employed to develop the ANN models. ANN models were trained, validated and tested with the registered clinical data using different ANN architectures. RESULTS Feedforward backpropagation ANN model with an architecture of 4-5-1, predicts post-Streptococcus mutans with an efficiency of 0.99033, mean squared error and mean absolute percentage error for testing cases were 0.2341 and 4.967 respectively. CONCLUSIONS Caries excavation methods and pre-Streptococcus mutans are feed as inputs, while post-Streptococcus mutans as targets to develop ANN model. Based on the developed ANN model, an ingenious iOS App was developed, the global clinician may utilize the App to meticulously predict post-Streptococcus mutans on iPhone based on pre-Streptococcus mutans, which in turn aids in decision making for the selection of caries excavation method. This study manifests the potential application of iOS App with built-in ANN model in efficiently predicting the post-Streptococcus mutans. Also, the study extends scope for applications of iOS App with built-in ANN models in clinical medicine.

Abstract
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.

Abstract
Aim To compare and evaluate morphological changes and bacterial deposits in primary carious molars after caries excavation with Carie-Care, erbium-doped yttrium aluminum garnet (Er:YAG) laser, and round tungsten carbide bur. Materials and methods Thirty human carious primary molars extracted for therapeutic reasons were sectioned mesiodistally. These sectioned samples were allocated into three groups (20 samples each): group I: Carie Care, group II: Er:YAG laser, and group III: round tungsten carbide bur. After caries excavation, all samples were processed and examined under conventional light microscope to examine for bacterial deposits. Representative samples from each group were processed and analyzed to examine the morphology of caries-excavated tissue by scanning electron microscope (SEM). Statistical analysis was done using Fisher’s exact test, Kruskal–Wallis test, and Mann-Whitney U test. Results The Er:YAG laser showed best results with no smear layer followed by chemomechanically excavated surfaces with Carie-Care. Amount of bacterial deposits was observed to be more in group I while least in group II (p-value < 0.001). Mann-Whitney U test and Fisher’s exact test revealed that there was statistically significant difference among all the three groups. Conclusion Among the three different methods of caries excavation, Er:YAG laser was found to be more effective compared with Carie-Care and round tungsten carbide bur. Clinical significance Laser-induced caries excavation by Er:YAG laser and chemomechanical method of caries removal by Carie-Care can be considered as future of noninvasive pediatric and preventive dentistry.

Abstract
Objective: To compare the effectiveness of various caries removal techniques in mandibular primary molars using Smart Burs, atraumatic restorative technique (ART) (mechanical caries removal) and Carie-care (chemomechanical caries removal [CMCR]) among primary school children in clinical and community-based settings. Materials and Methods: A total of 80 carious primary mandibular molars were selected for the study from the dental clinic and community. They were equally assigned to four groups according to caries removal technique and also by the operating site. In Group 1, caries was removed using Carie-care in the dental clinic and in Group 2, with Smart Burs in the dental clinic. In Group 3, caries was removed using Carie-care in the field and in Group 4, with the ART in the field. The time taken for caries removal, the efficacy of caries removal and patient acceptance were evaluated with different caries removal techniques. Statistical Analysis: The obtained data were subjected to statistical analysis by ANOVA test. Results: In clinical settings, Carie-care was time-consuming but was more efficient with increased acceptance than Smart Burs and the result was found to be significant statistically (P < 0.05). In community-based settings, Carie-care was more efficient, less time consuming, and showed an increased acceptance when compared to atraumatic restorative treatment and the result was found to be significant statistically (P < 0.05). Conclusions: The CMCR technique was superior to the mechanical caries removal technique in primary teeth among school children in terms of time, efficacy, and acceptance in both clinical- and community-based settings.
