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.

Multidisciplinary Approach for the Management of Mandibular Canines with Rare Configuration.

J Pharm Bioallied Sci 2020 Aug 28;12(Suppl 1):S635-S639. Epub 2020 Aug 28.

Department of Pedodontics, Faculty of Dentistry, Asian Institute of Medical, Science and Technology University, Bedong, Kedah, Malaysia.

It is very rare (2%-6% cases) for a mandibular canine to have two root canals and the incidence of finding two roots with two root canals in a mandibular canine that too bilaterally is almost negligible. This case report discusses the presence and multidisciplinary management of such rarest configuration in both mandibular canines of a female patient. This case shows the importance of recognition of anatomical variations in successful accomplishment of root canal treatment.

Relation between Apical Seal and Apical Preparation Diameter: An Study.

J Pharm Bioallied Sci 2020 Aug 28;12(Suppl 1):S332-S335. Epub 2020 Aug 28.

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

Background: The current recommendations for the apical preparation diameter, one of the most important mechanical imperatives in the apical third preparation, are to preserve the apical foramen in its original position along with its narrowest diameter to avoid any complication such as tearing, zipping, or transport of the foramen. The aim of our study was to see the correlation between apical seal and apical preparation diameter.

Materials And Methods: In total, 90 extracted maxillary incisors were randomly allocated into three groups of 30 teeth each according to the apical preparation size: Group 1: finishing file F1 corresponding to size 20 reached the working length, Group 2: prepared up to size 30 corresponding to finishing file F3, and Group 3: prepared up to size 50 corresponding to finishing file F5. After the filling of the root canals, the teeth were isolated and immersed in a dye solution, then cut longitudinally, photographed, and the dye penetration were calculated using a computer software.

Results: Comparison of the three different apical preparation sizes showed no statistically significant differences regarding the apical microleakage.

Conclusion: The most important value of the dye penetration was observed in the group with the largest apical diameter.

Evaluation of Knowledge and Preparedness Among Indian Dentists During the Current COVID-19 Pandemic: A Cross-Sectional Study.

J Multidiscip Healthc 2020 24;13:841-854. Epub 2020 Aug 24.

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.

Prosthodontic Management of a Pediatric Patient with Christ-Siemens-Touraine Syndrome: A Case Report.

Int J Clin Pediatr Dent 2019 Nov-Dec;12(6):569-572

Department of Pediatric Dentistry and Orthodontic Sciences, King Khalid University, Abha, Kingdom of Saudi Arabia.

Ectodermal dysplasias (ED) are a group of rare genetic disorders characterized by congenital defects involving two or more ectodermal structures. Christ-Siemens-Touraine syndrome or hypohidrotic ectodermal dysplasia is the commonest form of ED. Hypohidrotic ectodermal dysplasia (HED) is an X-linked disorder characterized by excessively dry skin due to the absence of sweat glands (anhidrosis), sparse body hair especially on the scalp and eyebrows (hypotrichosis), brittle nails, absence of sebaceous glands (asteatosis) and malformed or absent teeth. Oral manifestations include oligodontia or complete anodontia, conical teeth, underdeveloped alveolar ridges, generalized spacing and delayed eruption of permanent teeth. This case report discusses a classical case of HED and the options for rehabilitation in a growing patient. A thorough knowledge about the clinical manifestations of ED will lead to proper diagnosis and appropriate treatment plan thereby leading to significant improvements in esthetics, phonetics and masticatory function in ED patients, which in turn leads to improved quality of life in these individuals.

Comparative Evaluation of Erosive Potential of Various Frozen and Unfrozen Fruit Juices on Primary Teeth Enamel: An Study.

J Pharm Bioallied Sci 2019 May;11(Suppl 2):S463-S467

Faculty of Dentistry, Asian Institute of Medicine, Science and Technology (AIMST) University, Kedah, Malaysia.

Background: Changing lifestyle pattern and food habits has a deteriorating effect on dental tissues. Dental erosion is a pathological wear of hard tissues of teeth with increased consumption of acidic and carbonated drinks. Susceptibility to erosion in primary dentition is more compared to permanent dentition due to softer and disordered crystal structure of enamel.

Objectives: The main aim of the study was to determine and compare the erosive potential of different fruit juices in frozen/unfrozen forms on primary teeth by studying the calcium dissolution.

Materials And Methods: pH of four different juices (pure) - apple, orange, citrus limetta (musumbi) and grapes were determined using a digital pH meter. The titratable acidity of these in frozen and unfrozen forms were determined by adding 0.2 ml of 1M NaOH to these to raise to pH=5.5(critical pH) and pH =7(neutral pH). Forty eight caries free deciduous anterior teeth specimens were prepared to study the calcium dissolution by atomic absorption spectrophotometer. The results were analysed for statistical significance using One-way Repeated Measures ANOVA and pair wise multiple comparison with Bonferroni correction.

Results: Total titratable acidity and calcium dissolution were found to be significantly more in the initial thawed fruit juices.

Conclusion: Frozen fruit juices had more buffering capacity and erosive potential than unfrozen forms. The study concluded that sucking on frozen fruit juices is more damaging to teeth than unfrozen forms because more of erosion is expected to occur in a frozen state.

A Comparative Evaluation of Five Obturation Techniques in the Management of Simulated Internal Resorptive Cavities: An Study.

J Pharm Bioallied Sci 2019 May;11(Suppl 2):S450-S456

Department of Preventive Dental Science, College of Dentistry, King Khalid University, Abha, Saudi Arabia.

Background: Root resorption is the loss of dental hard tissues as a result of clastic activities. It might be broadly classified into external or internal resorption by the location of the resorption in relation to the root surface. the various techniques used these days for filling internal resorption include warm condensation, vertical condensation, core techniques, thermoplasticized gutta-percha, warm vertical compaction, and cold lateral condensation.

Objectives: The aims and objectives of this study were to compare the quality of root fillings in artificially created internal resorption cavities filled with warm vertical compaction, lateral condensation, Obtura II along with System B, E and Q plus along with System B, and Thermafil, and to calculate the percentage of gutta-percha, sealer, and voids using an ImageJ software.

Results: Results between the warm vertical compaction (group I), lateral condensation (group II), Obtura II with System B (group III), E and Q plus with System B (group IV), and Thermafil (group V), group III showed the highest percentage of gutta-percha plus sealer and gutta-percha, and least number of voids, which was statistically significant ( < 0.000).

Conclusion: It can be concluded that Obtura II along with System B was found to be the most suitable obturation technique for the management of teeth exhibiting internal resorption. Thermafil was found to give the poorest obturation quality when used to fill the teeth with internal resorption. Similarly, lateral condensation technique was observed to show maximum sealer and hence was not ideal for the management of internal resorptive cavities.
