Antibiotics (Basel) 2021 May 9;10(5). Epub 2021 May 9.

Department of Restorative Dental Sciences, College of Dentistry, King Khalid University, Abha 61321, Saudi Arabia.

Background And Objectives: This study aimed to evaluate the synergistic antimicrobial activity of extracts obtained from (Miswak), (myrrh) and (neem) in combination with commercially available antimicrobial agents: penicillin, tetracycline, ofloxacin and fluconazole on endodontic pathogens such as and .

Materials And Methods: Microbiological samples from the root canals of the teeth undergoing retreatment were taken using sterile paper points kept at full length in the canal for 30 s. The disc diffusion method was used to check the susceptibility of microbes to the plant extracts and antimicrobials by measuring the diameter of the inhibition zones. Against the microbes, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)/minimum fungicidal concentration (MFC) of the plant extracts were assessed. The fractional inhibitory concentration index (FICI) was used to estimate the synergistic effect of plant extracts combined with antimicrobials against the resistant endodontic microbes.

Results: The findings clearly indicate the effectiveness of all the three plant extracts, against all the experimental pathogenic microorganisms except for the ineffectiveness of against Maximum antimicrobial activity was displayed by against (MIC = 0.09 ± 1.2 mg/mL, MBC = 0.78 ± 1.25 mg/mL) and the minimum antimicrobial activity was displayed by against (MIC = 12.5 ± 3.25 mg/mL, MBC = 100 ± 3.75 mg/mL). The best synergy was displayed by with fluconazole against (FICI = 0.45).

Conclusions: The current study delineates the variable antimicrobial activity of plant extracts against the experimental endodontic pathogenic microorganisms. Plant extracts in conjunction with various antimicrobials can be valuable aids in combating relatively resistant endodontic microorganisms that have been the cause of worry in recent years, leading to failure even in treatment procedures following all required protocols.

Recent update on potential cytotoxicity, biocompatibility and preventive measures of biomaterials used in dentistry.

Biomater Sci 2021 May;9(9):3244-3283

Faculty, Department of Pharmaceutics, School of Pharmaceutical Education and Research, Jamia Hamdard, New Delhi, 110062, India.

Dental treatment is provided for a wide variety of oral health problems like dental caries, periodontal diseases, periapical infections, replacement of missing teeth and orthodontic problems. Various biomaterials, like composite resins, amalgam, glass ionomer cement, acrylic resins, metal alloys, impression materials, bone grafts, membranes, local anaesthetics, etc., are used for dental applications. The physical and chemical characteristics of these materials influence the outcome of dental treatment. It also impacts on the biological, allergic and toxic potential of biomaterials. With innovations in science and their positive results, there is also a need for awareness about the biological risks of these biomaterials. The aim of dental treatment is to have effective, yet safe, and long-lasting results for the benefit of patients. For this, it is important to have a thorough understanding of biomaterials and their effects on local and systemic health. Materials used in dentistry undergo a series of analyses before their oral applications. To the best of our knowledge, this is the first and original review that discusses the reasons for and studies on the toxicity of commonly used biomaterials for applications in dentistry. It will help clinicians to formulate a methodical approach for the selection of dental biomaterials, thus providing an awareness for forecasting their risk of toxic reactions.

Orthodontics and Dentofacial Orthopedics, Department of Preventive Dental Sciences, College of Dentistry, King Khalid University, Abha 61321, Kingdom of Saudi Arabia.

Purpose: The current scenario of the COVID-19 pandemic has forced dentists to prepare themselves by updating their knowledge and receive training to face the present and after effects of COVID-19. The present survey was thus conducted to assess the knowledge, risk perception, attitude, and preparedness of the dentists in India about COVID-19.

Materials And Methods: A cross-sectional online survey was carried out among registered dentists in India. A self-administered, anonymous, questionnaire comprising of 25 close-ended questions was circulated to gather the relevant information. A total of 765 dentists submitted a response, out of which 646 complete responses were included in the statistical analysis. Pearson's Chi-square test was used for inter-group statistical comparison.

Results: The majority (80.8%) of the dentists had a fair knowledge about the characteristics of COVID-19. Nearly 60.7% and 49.7% of the dentists had taken infection control training and special training for COVID-19, respectively. Nearly 50% of the dentists had the perception that COVID-19 is very dangerous. Only 41.8% of the dentists were willing to provide emergency services to patients. Most of the dentists had an opinion that there is a need to enhance personal protective measures. During the survey, it was found that varied technological advances are offered to dentists to ensure good clinical practice. They also concurred that there was a need to standardize the tools and measures available to carry out dental practices.

Conclusion: In the present study, Indian dentists have presented satisfactory knowledge with adequate preparedness as the majority of them had a fair level of knowledge with significantly higher knowledge among female respondents and those with post-graduation studies. Dentists should make judicious utilization of all the precautionary measures to safely practice dentistry. As we are going through an evolutionary phase where new advances are expected to evolve, dentists will definitely emerge successfully out from the crisis of the COVID-19 pandemic.

J Contemp Dent Pract 2020 Jan 1;21(1):73-77. Epub 2020 Jan 1.

Department of Pediatric Dentistry and Orthodontics, College of Dentistry, Division of Orthodontics, King Khalid University, Abha, Kingdom of Saudi Arabia.

Aim: The present study aimed to evaluate the sealing potential and marginal adaptation of different root canal sealers to dentin.

Materials And Methods: A total of sixty human lower premolars of the permanent dentition that were extracted were used for this study. The visible debris and calculus were removed from the extracted teeth ultrasonically and were kept for 2 hours in 2.5% sodium hypochlorite and stored in normal saline till next use. A low-speed diamond disc was used to section all the teeth samples at the cementoenamel junction. Later, cleaning and shaping of the canals was done. Based on the sealer used, the samples (each group consisting of 20 samples) were divided randomly into three groups: group I-bioceramic sealer, group II-resin-based sealer, group III-MTA-based sealer. All split samples were visualized under scanning electron microscope (SEM) at apical and coronal thirds of root canal, the marginal gap at root dentin and sealer interface were assessed.

Results: The highest marginal adaptation (5.60 ± 0.12) was demonstrated by EndoSequence BC sealer, followed immediately by ProRoot MTA sealer (4.48 ± 0.12) and EndoREZ sealer (2.10 ± 0.54). A statistically significant difference ( = 0.001) was seen between the EndoSequence BC and ProRoot MTA sealer for apical and coronal marginal adaptation. Also, a statistically significant difference ( < 0.05) was found between EndoSequence BC sealer vs EndoREZ sealer at coronal and EndoSequence BC sealer vs EndoREZ sealer and EndoREZ sealer vs ProRoot MTA sealer at apical third.

Conclusion: The present study concluded that significant and better sealing ability and marginal adaptation was demonstrated by EndoSequence BC (bioceramic sealer) when compared to ProRoot MTA sealer (MTA-based sealer) and EndoREZ sealer (resin-based sealer).

Clinical Significance: Numerous endodontic sealers enter the market with various factors to attain acceptable seal. According to current study bioceramic sealer, is the appropriate sealer that hermetically seals all the margins.

Department of Conservative Dentistry and Endodontics, Sri Balaji Dental College and Hospital, Moinabad, Hyderabad, Telangana, India.

Aim: To assess the different polishing systems on the color stability and surface roughness of nanocomposite resins.

Materials And Methods: A total of 60 composite resin samples were fabricated. The Tetric N Ceram composite was compacted into the custom-made cylindrical metallic mold of internal diameter 6 × 6 mm. Based on the polishing system used, sixty samples were divided into three groups. Group I: Sof-Lex, group II: Shofu super-snap polishing disks, and group III: Astropol. The samples in each group were immersed in beverage, that is tea. Spectrophotometer was used to measure the color of the samples after staining period. And surface profilometer was used to measure all surface roughness.

Results: Of the three groups, Sof-Lex polishing group reported the least mean value of 0.458 ± 0.118 succeeded by Astropol polishing group (0.494 ± 0.121) and Shofu super-snap polishing group (0.540 ± 0.031) having the higher mean value. Statistically significant difference was found between the different polishing systems calculated by analysis of variance. And color change between the groups was not statistically significant.

Conclusion: We conclude that a composite polished with Sof-Lex was a superior polish compared to Astropol polishing group and Shofu super-snap polishing group. There was only a minimal difference in the color stability of the composite between the groups.

Clinical Significance: Excellent finishing and polishing are the critical steps to enhance the esthetics and longevity of the composite restorations. High strength, fracture toughness, surface hardness, optimum polishability, and gloss are the functional properties which need assessment while a resin composite is used for restoration.

J Contemp Dent Pract 2019 Nov 1;20(11):1269-1273. Epub 2019 Nov 1.

Department of Pedodontics and Preventive Dentistry, SJM Dental College and Hospital, Chitradurga, Karnataka, India.

Aim: The aim of the present study was to evaluate the efficacy of different instrumentation for removal of gutta-percha and sealers in endodontic retreatment.

Materials And Methods: A total of single-rooted mandibular premolars were collected. Access opening was performed in all specimens. The working length was determined by reducing 1 mm from the length of instruments that were seen reaching the apex. All the canals were dried with paper points. Lateral condensation technique was used to obturate the canals with gutta-percha and zinc oxide eugenol was used as a sealer. The specimens were randomly segregated into three experimental groups. Group I: ultrasonic retreatment tip, group II: R-Endo retreatment files, group III: Mtwo retreatment files. Roots were grooved into two halves with a diamond disc in a longitudinal, buccolingual direction. A stereomicroscope with ×40 magnification was used to image the quantity of gutta-percha and sealer on canal walls.

Results: With ultrasonic retreatment tip, least amount (1.96 ± 0.32) of gutta-percha and sealer remained, followed by Mtwo retreatment files (2.84 ± 0.24) and R-Endo retreatment files (3.18 ± 0.63). A statistically significant inter-group difference among different instrumentation groups was demonstrated by ANCOVA analysis.

Conclusion: In the present study, ultrasonic retreatment tip file systems was found to be more effective in the removal of root canal filling material, followed subsequently by Mtwo retreatment file system and R-Endo retreatment file system.

Clinical Significance: Thorough removal of filling material from the root canals is essential during root canal retreatment for probable cleaning and shaping of canal morphology. Thus, clinicians should be aware of the suitable and better instrumentation system that provides a clean and sterile root canal system without any debris.

J Contemp Dent Pract 2019 Feb 1;20(2):179-183. Epub 2019 Feb 1.

Department of Conservative Dentistry and Endodontics, Mahe Institute of Dental Sciences and Hospital, Mahe, Kerala, India.

Aim: The aim of the present study was to compare the anti-microbial efficacy of various intracanal medicaments against and Materials and methods: Sixty single rooted, non-carious, permanent mandibular premolars with no developmental defects that were previously extracted for the orthodontic purpose were included in this study. and strains were cultured on brain heart infusion (BHI) and sabouraud dextrose (SD) agar plates respectively. Sixty specimens were divided into two main groups and three subgroups with 10 teeth receiving a medicament; group I: (Subgroup Ia: BioPure MTAD, Subgroup Ib: propolis, Subgroup Ic: Triple antibiotic paste), group II: (Subgroup IIa: BioPure MTAD, Subgroup IIb: propolis, Subgroup IIc: Triple antibiotic paste). The antimicrobial activity of the intracanal medicaments against E. faecalis and C. albicans were assessed at the end of 2nd and 7th day. The mean zones of inhibition were analyzed with a one-way ANOVA test.

Results: After 2 days, the mean zone of inhibition of and was maximum for triple antibiotic paste (24.74 ± 0.622 mm, 28.22 ± 0.489 mm), followed by BioPure MTAD (19.58 ± 1.734 mm, 24.75 ± 0.954 mm) and propolis (13.10 ± 0.278 mm, 17.96 ± 0.163 mm). Similarly, the mean zone of inhibition of and was maximum for triple antibiotic paste (26.86 ± 0.112 mm, 32.10 ± 0.908 mm), followed by BioPure MTAD (20.13 ± 1.842 mm, 27.22 ± 1.977) and propolis (14.11 ± 0.101 mm, 19.90 ± 0.742 mm) after 7 days. Statistically significant differences ( <0.0001) were found between the groups.

Conclusion: Present study concluded that the antimicrobial effectiveness of triple antibiotic paste was significantly more than BioPure MTAD and propolis against and at the end of 2nd and 7th day.

Clinical Significance: An endodontic treatment is considered successful only when the root canals are completely eradicated of microorganisms. As the morphology of the root canals is complex, mechanical instrumentation alone cannot completely debride them. Thus, the role of intracanal medicaments in complementing the mechanical instrumentation becomes important.

J Contemp Dent Pract 2018 Dec 1;19(12):1463-1468. Epub 2018 Dec 1.

Department of Pediatric and Preventive Dentistry, Sree Anjaneya Institute of Dental Sciences, Calicut, Kerala, India.

Aim: This study aimed to evaluate the efficacy of Intracanal calcium hydroxide removal with different techniques.

Materials And Methods: Seventy-five freshly extracted, non-carious, single canalled lower first premolars, having anatomic characteristics similar to each other, extracted for the orthodontic purpose were collected. After the root canal preparation, Calcium hydroxide was placed into the working length using lentulo spiral instrument till the medicament was visible at the apex. The specimens were segregated into three groups; Group 1: Rotary Files, Group 2: EndoVac system and Group 3: Ultrasonics. The evaluation was done with SEM in the coronal and apical third of the roots with a magnification of 1000x. The statistical analysis was done using statistical packages for social sciences (SPSS) software, version 20.0 for Windows (SPSS Inc., Chicago, IL). A p-value of less than 0.05 was considered significant statistically.

Results: Maximum removal of Ca(OH) was analyzed in the EndoVac system (2.90 ± 0.12) followed by the rotary files (1.76 ± 0.26) and least was seen with Ultrasonics (1.32 ± 0.14). The p-value of 0.001 was seen between the coronal and apical third with the EndoVac system which is statistically significant. The significant difference statistically was observed between Rotary Files vs. Ultrasonics at apical third and with the EndoVac system vs. Ultrasonics at coronal third as well as at the apical third with p-value 0.001.

Conclusion: It can be concluded that the EndoVac technique was effective in removing Ca(OH) medicament from the coronal and apical third of the root canal significantly.

Clinical Significance: Calcium hydroxide removal before the obturation was of priority as the Ca(OH) remnants have a negative impact of the ability for sealing the obturation material. Therefore, having a complete knowledge regarding the effective technique is much important.

Evaluation of Antimicrobial Efficacy of Root Canal Sealers against Enterococcus faecalis: A Comparative Study.

J Contemp Dent Pract 2018 Jun 1;19(6):680-683. Epub 2018 Jun 1.

Department of Pedodontics and Preventive Dentistry Awadh Dental College and Hospital, Jamshedpur, Jharkhand India.

Aim: The study aimed to evaluate the efficacy of root canal sealer's antimicrobial activity against Enterococcus faecalis.

Materials And Methods: Root canal sealers with the brands Endoflas FS, AH Plus, and Tubli-Seal EWT were selected. Enterococcus faecalis organisms' zone of inhibition was measured. Tukey post hoc tests and one-way analysis of variance (ANOVA) were used to compare the data among study groups and within its group. The data were said to be statistically significant with an established p-value less than 0.05.

Results: The maximum zone of inhibition (23.20 ± 1.202 mm) was shown by Endoflas FS sealer; AH Plus and Tubli-Seal showed the inhibition zone of (18.42 ± 1.023) and (16.88 ± 0.962) respectively, following Endoflas FS. The ANOVA test showed p < 0.0001, which is highly statistically significant. AH Plus and Endoflas FS showed a statistically significant difference of 0.04 and 0.001 in between groups, and there was no statistically significant difference in the Tubli-Seal group from Tukey post hoc test.

Conclusion: The study showed that Endoflas FS sealer has a significant antimicrobial effect against E. faecalis.

Clinical Significance: In clinical situation, despite perfect che-momechanical root canal preparation, persistence of microorganisms may reinfect the root canal. Therefore, endodontic root canal sealers play a major role in the eradication of bacteria. The polymicrobial nature of endodontic infection plays a main role during the usage of endodontic sealer with antimicrobial agents, which in turn reduces the failure of endodontic treatment.

Assessment of Fracture Resistance Capacity of Different Core Materials with Porcelain Fused to Metal Crown: An Study.

J Contemp Dent Pract 2018 Apr 1;19(4):389-392. Epub 2018 Apr 1.

Department of Restorative Dental Sciences, King Khalid University, Abha, Kingdom of Saudi Arabia.

The aim of the study was to evaluate the capacity to resist fracture in different core buildup materials with porcelain fused to metal (PFM) crown. Totally, 45 mandibular single rooted first premolars were collected, which were sound along with similar shape and size. The teeth were sectioned at 15 mm above the root apex sparing the sound tooth structure. The teeth were endodontically treated with the crown-down technique using nickel-titanium (NiTi) instrumentation. The specimens were randomized into three groups as per the core materials used and were labeled accordingly. Group I consisted of dual-cured composite resin, group II consisted of glass ionomer reinforced with resin, and group III consisted of Miracle mix. Universal loading machine is used for measuring the compres-sive load applied to fracture the tooth. The mean value of compressive strength was maximum in the dual cured composite resin (598.42 ± 22.64) followed by glass ionomer reinforced with resin (478.88 ± 26.74) and Miracle mix (442.16 ± 30.10). The results showed a significant difference statistically within the core materials used with p < 0.05. The results from the Tukey's test of multiple comparisons between dual-cured composite resin glass ionomer reinforced with resin, dual-cured composite resin Miracle mix, and glass ionomer reinforced with resin Miracle mix showed a highly statistical difference with p < 0.05, which is significant. This study showed that the dual-cured composite resin had maximum resistance to fracture compared with other core buildup materials on teeth which were endodonti-cally treated. Restoration of a tooth which is structurally compromised is a tricky job for all the dentists. Restoring it with a proper core buildup material with adequate fracture resistance makes the tooth structure stable. The core material should be able to resist all types of occlusal forces and to distribute it equally within the tooth structure. Core buildup, Crowns, Endodontically treated teeth, Fracture resistance.

The prevalence and pattern of cavitated carious lesions in primary dentition among children under 5 years age in Sirsa, Haryana (India).

J Int Soc Prev Community Dent 2015 Nov-Dec;5(6):494-8

Department of Conservative Dentistry, Jan Nayak Choudhary Devi Dental College, Sirsa, Haryana, India.

Background: To determine the prevalence and pattern of cavitated carious lesions in primary dentition in children below 5 years of age in Sirsa, Haryana.

Aims: The aim of this study was to evaluate the status of dental caries in primary dentition and compute data for planning anticipatory programs in children aged less than 5 years.

Settings And Design: The study was conducted among children attending the outpatient department of pedodontics, JCD Dental College, Sirsa, Haryana (India) from April to December 2014.

Materials And Methods: This study consisted of 576 children of both sexes (311 males and 265 females) up to 5 years of age. Dentition status and treatment proforma (WHO, 1997) was used to assess the prevalence of cavitated carious lesions. Selection of children for the study was done by simple random sampling method.

Statistical Analysis: Chi-square test and t-test were used to compute data for statistical analysis.

Results: 33.85% of children in the study population showed presence of cavitated carious lesions. Males showed slightly higher prevalence of cavitated carious lesions than females (P = 0.35). Incidence of caries was higher in mandibular arch in both the sexes (males P = 0.9, females P = 0.7) and in posterior teeth (both sex wise and arch wise). Higher caries prevalence was noticed in maxillary anterior teeth (P = 0.04) and mandibular posterior teeth (P = 0.7). Primary second molars showed highest caries prevalence (P = 0.39) in both the arches and sexes.

Conclusion: The mean prevalence of cavitated carious lesions in primary dentition was found to be 33.85%. Males were more affected than females. Mandibular molars and maxillary anterior teeth were the predominantly affected teeth. Mandibular anterior teeth were least affected. The increase in incidence of cavitated carious lesions shows that there is necessity of implementing dental health awareness programs and modifications in types of food consumed are needed to eliminate the cause of decay.
