Authors: Pawar Madhura , Kumari Neha , Gopal Ruchi , Nasha Divya , Bhuyan Lipsa , Verma Vartika 
Published: July 2023

ABSTRACT

Aim:
Chewable toothbrushes were compared to traditional manual toothbrushes in terms of their ability to remove plaque and their impact on salivary pH in a sample of school-aged children.

Materials and Methods:
The sample size for this research was 200 youngsters aged 10–12. Saliva was collected by spitting into a clean container, and the pH levels were measured using color-coded pH strips to determine where the person was starting from. The plaque score was measured using the OHI-S index after the application of the disclosing agent. The pH and plaque scores were also recalculated after brushing to see how they had changed after surgery.

Results:
Results indicated that both manual and chewable brushes significantly improved post-brushing pH ratings (P = 0.001), and that plaque scores decreased (P = 0.001). When compared to conventional manual toothbrushes, the chewable brush was much more successful in reducing plaque and elevating salivary pH (P = 0.001).

Conclusion:
As a result, parents may offer their kids a chewable toothbrush to help them maintain good oral hygiene after lunch and on lengthy car trips, when they would not have time to wash their teeth properly.

Published: July 2023

ABSTRACT

Aim:
In order to determine which species of Candida were isolated from hospitalized patients’ urine, which risk factors they were linked to, and which antifungal drugs were effective against them, the current investigation was carried out.

Materials and Methods:
One hundred inpatients were part of the study group. Urine samples were collected from each subject and spun at 3000 rpm for 10–15 minutes in individual sterile centrifuge tubes. Color, size, texture, and the presence of color diffusion into the surrounding agar were used to identify the distinct Candida species, presumably in 48 hours.

Results:
A total of 86.7% of the Candida spp. were found to be non-albicans. Major inaccuracies occurred because of differences between methodologies; thus, MBD is the best way to determine antifungal susceptibility to itraconazole and amphotericin B.

Conclusion:
To help clinicians decide on an empirical treatment in an emergency, accurate identification of Candida down to the species level is crucial.

Published: July 2023

ABSTRACT

Background:
Dentistry is a resource-intensive discipline of healthcare that has a notable impact on the environment. Sustainability should be the major consideration for healthcare service providers to support climate change policies. Green dentistry is an efficient strategy for practicing eco-friendly dentistry. This study was conducted to assess the awareness, knowledge, and barriers to practicing green dentistry among dental practitioners and dental students.

Materials and Methods:
A cross-sectional, descriptive-analytical online questionnaire survey with 22 questions was carried out.

Results:
51.8% of participants were not aware of the concept of green dentistry. Practitioners of the age group 20-30 years are more willing to transform their dental practice into green practice to reduce the carbon footprint of their clinic (P < 0.05). Chi-square data analysis shows that dental practitioners treating more than 20 patients in a week have a better awareness of the concept of green dentistry (P < 0.05).

Conclusion:
Within the limitations of this study, dental professionals in the younger age group are eager to transform their dental practices to green practices to lessen their clinics’ carbon footprints. Financial constraints limit the implementation of green dentistry into clinical practice.

Published: July 2023

ABSTRACT

Aim:
To evaluate the biomechanical properties of maxillary second molars with three different cavity designs – Traditional, Conservative, and Extended – endodontic cavities using the finite element analysis method.

Materials and Methods:
Three finite element models of a maxillary second molar with three different types of endodontic cavities were designed and restored. Each model was subjected to three different force loads directed at the occlusal surface. The stress distribution patterns and the maximum von Mises (VM) stresses were calculated and compared.

Results:
Vertical force of multipoint load on the occlusal surface and lateral forces to the palatal cusp showed the maximum stress values in the extensive cavity design, followed by the traditional cavity design and then the conservative cavity design.

Conclusion:
The VM stress distribution in the conservative endodontic cavity was minimal when compared to other access cavity designs.

Published: July 2023

ABSTRACT

Background:
OSMF is now recognized worldwide as an Indian disease. Blanching and rigidity of the oral mucosa, impaired mobility of the soft palate and tongue, difficulty opening the mouth, burning sensation, lack of gustatory sensation, and mild deafness due to Eustachian tube dysfunction. Soft palatal muscles often affect Eustachian tube function.

Materials and Methods:
Rama Dental College Hospital and research center Kanpur conducted a cross-sectional study. 60 OSMF patients were randomly selected for this study. Visible light was used for a detailed case history and clinical examination. OSMF was diagnosed by difficulty opening the mouth, blanched oral mucosa, and palpable fibrous bands. Burning, salivation, tongue protrusion, habits, and malignant changes were also diagnostic. ENT specialists used pure tone audiometry to examine the ear (PTA).

Results:
Out of 60 patients 59 were males and 1 female. The participants who took part in this study ranged in age from 18 to 65. Pure tone audiometry of 120 years, 84 (70%) revealed normal hearing, 10 (8.33%) revealed minimal hearing loss, 14 (11.67%) revealed mild hearing loss and 12 (10%) revealed moderate hearing loss.

Conclusion:
In order to improve the success rate of treatment, the protocol for managing OSMF patients should therefore include ENT consultation and hearing impairment treatment.

Published: July 2023

ABSTRACT

Background and Objectives:
The aim of this study was to see the incidence of cracks in root dentin after coronal flaring using various rotary instruments such as Gates Glidden (GG) drills, ProTaper Universal SX, OneFlare, and HyFlex EDM.

Materials and Methods:
Seventy freshly extracted premolar teeth with single canal were collected. All the teeth were randomly divided into five groups of fourteen each (n = 14), of which one group served as the control and the rest of the four groups were instrumented with GG drills, ProTaper Universal SX, OneFlare, and HyFlex EDM, respectively.

Results:
The GG drills resulted in a higher rate of crack formation in root dentin (P < 0.05) than the ProTaper Universal SX, OneFlare, and HyFlex EDM instruments (P > 0.05).

Conclusion:
The use of GG drills resulted in more crack formation. However, the results for the ProTaper Universal SX, OneFlare, and HyFlex EDM flaring instruments were less in terms of crack formation.

Published: July 2023

ABSTRACT

Introduction:
Extraction of the tooth often leads to crestal bone loss. It is difficult for clinicians to decide on the technique of extraction. Many studies on flap and flapless have led to confusion. Hence it becomes necessary to conduct this study to show the efficient ridge preservation technique.

Materials and Methods:
Twenty patients were selected for this study. It was divided into the flap and flapless groups. In group A, the flap was elevated, tooth extraction was undertaken, the socket was cleaned, a graft was placed, a barrier was placed, and a suture was placed. In group B all the procedures were the same but without flap elevation. After surgery, clinical and radiographical parameters were recorded.

Result:
Flapless technique showed a better result in bone preservation. There was a low vertical bone loss in the flapless technique.

Conclusion:
Both techniques showed bone loss. But the flapless technique gave better results.

ABSTRACT

Background:
To investigate the effect of N. nucifera hydroalcoholic seed extract on fasting blood glucose (FBG) levels, glucose transporter (GLUT)-4 mRNA, and GLUT-4 protein in the adipose tissue of streptozotocin (STZ)-induced diabetic rats.

Materials and Methods:
Male Sprague Dawley (SD) rats were first fed with a high-fat diet (HFD) for three weeks, and then, diabetes was induced by intraperitoneal injection of STZ at a dose of 35 mg/kg bw. Rats were divided into four groups: group 1: normal rats (NC), group 2: STZ-induced diabetic rats (DC), group 3: diabetic rats with N. nucifera hydroalcoholic seed extract at a dose of 400 mg/kg bw (NN), and group 4: diabetic rats with metformin at a dose of 100 mg/kg bw (MET) for 28 days.

Results:
FBG level was significantly lower in the NN group than in the DC group (P < 0.05). Also, the NN group increased GLUT-4 mRNA expression and GLUT-4 protein in the adipose tissue when compared to the diabetic group.

Conclusion:
We conclude that the observed hypoglycemic effect of N. nucifera seed extraction in STZ-induced diabetic rats could be due to insulinomimetic activity.

Published: July 2023

ABSTRACTBackground:Hepatocellular adenomas (HCAs) are benign tumours that may be broken down into three different molecular pathogenic categories: catenin activator, hepatic cell nuclear agent 1 (HNF- 1) that has been inactivated, and Inflammatory hepatic adenomas are a genetic and pathological subtype of hepatic adenoma.Methodology:An analysis of 50 HCA cases was conducted to identify the magnetic resonance imaging characteristics that were specifically related to each HCA subtype IV. This method included 50 patients in total for the study, with 30 of them being new cases. Four cases involving medicine, pathology, surgery, and radiology were gathered and examined.Results:As per these analyses for inactivated HNF-1, the sure predictive esteem about homogeneous indicator spillage on the compound shift pictures could have been as high as 100%, negative predictive quality could have been as high as 94.7%, affectability could have been as high as 86.7%, and specificity could have been as high as 100%. Enhancement of the solid blood vessels to support the ongoing and future stages of the portal vein change. It took a certain predictive quality of 88.5%, a negative predictive worth of about 84%, an affectability of about 85.2%, and more specificity of about 87.5% to diagnose incendiary HCA from the predominant signs seen for T2W successions linked with late constant upgrades.Conclusions:Both HNF-1–mutated HCAs and incendiary HCAs need to be associated with specific magnetic resonance imaging phenotypes characterized independently as having diffused lipid repartition and sinusoidal expansion.

Published: July 2023

ABSTRACT

Background:
Solid multicystic ameloblastoma (SMA) is a locally aggressive, benign odontogenic tumor of odontogenic origin with greater rate of recurrence. Epithelial-mesenchymal interaction plays an important role in tooth morphogenesis that shows complete differentiation of epithelial and ectomesenchymal components to the level of tooth formation. Tumor stroma in ameloblastoma is normal mature collagen that prevents differentiation to the level of tooth formation. Current study evaluates the role of stromal elements in aggressive behavior of SMA using picrosirius red staining with polarizing microscopy and CD44v6 immunohistochemistry (IHC).

Objectives:
To compare nature of collagen using picrosirius red staining under polarized microscope and IHC expression of CD44v6 marker in SMA and oral squamous cell carcinoma (OSCC).

Methods:
Thirty blocks were retrieved from departmental archives and subjected to picrosirius red staining and CD44v6 IHC staining. Slides stained with picrosirius red were observed under polarized microscope to report the birefringence pattern. IHC slides were annotated for intensity of staining of tumor cells.

Results:
In contrast to OSCC’s 40% red, 40% yellowish-red, and 20% greenish-yellow birefringence, SMA displayed 87% red, 13% yellowish-red, and 0% greenish-yellow. Compared to OSCC, which had tumor cells stained 9% strongly, 64% moderately, 27% mildly, and 0% negatively, SMA revealed 0% strong, 10% moderate, 60% weak, and 30% negative staining.

Conclusion:
As opposed to OSCC, which exhibited a greater quantity of greenish-yellow birefringence of immature collagen, SMA showed predominantly red birefringence, which is suggestive of mature collagen with a lack of metastasis. Comparing SMA to OSCC, the lack of significant CD44v6 positivity suggests that there has not been perineural invasion or regional metastases in SMA.

Published: July 2023

ABSTRACT

Background and Aims:
For endodontic therapy to be successful, the smear layer produced by the root canal instruments must be removed. The study’s objective is to evaluate the effectiveness of radicular dentin microhardness modification and smear layer removal utilizing various chelating agents.

Materials and Methods:
Extracted human mandibular single-rooted premolar teeth were selected for the study. The specimens were sectioned to obtain a standard root length and, working length determination was done. Cleaning and shaping were done in all the samples till the size F3 (Protaper universal). Based on the chelating agents using samples were randomly divided into four groups, Group-I: Saline (negative control), Group-II: 17% EDTA (DeSmear, Ahmedabad, Gujarat) (positive control), Group-III: 0.2% Chitosan (Everest-Biotech, Bengaluru), Group-IV: 20% N-Acetyl cysteine (NAC) (Sisco Research Laboratories, Mumbai), Group-V: 5% Pentetic acid (New Alliance Fine chem Pvt Ltd, Mumbai). All the samples were prepared for smear layer removal and surface roughness evaluation using an atomic force microscope.

Results:
It was observed that significantly (P = 0.000) the mean roughness average was higher among group II EDTA (148 ± 8.5) followed by group III 0.2% Chitosan (92.5 ± 3.42), group IV 20% NAC (85.2 ± 2.17), and group V 5% Pentetic acid (73.3 ± 3.39) and least by group I Saline (59.3 ± 3.31). The highest smear layer removal was seen with group II (EDTA) followed by group III (0.2% Chitosan), group IV (20% NAC), and group V (Pentetic acid).

Conclusion:
All the chelating agents removed smear layer in coronal third, middle third whereas none of them were able to entirely eliminate from the apical third. Chitosan with smear layer removal capacity equal to EDTA with limited roughness can be considered as a valid alternative as final irrigant.

Published: July 2023

ABSTRACT

Aim:
To evaluate correlation of PRF and HAS with glycemic control (HbA1c) and other systemic parameters amongst the chronic periodontitis patients.

Materials and Methods:
Twenty-seven non-smoker, non-tobacco users, non-alcoholic moderate chronic periodontitis volunteers (Stage II, Grade A or B), aging between 40 and 50 years of both genders with type 2 diabetes mellitus (T2DM, HbA1c >6.5%) or without T2DM (HbA1c <6.5%), were recruited. After recording vitals and demographic parameters, 20 ml of intravenous fasting blood was collected, of which 11 ml blood was used for investigating complete blood count, lipid profile, glycated hemoglobin (HbA1c), C-reactive protein, and fasting insulin level. As per the standard protocol, PRF and HAS was prepared from the 9-ml blood sample of the patients. PRF obtained was quantified using Wensar’s analytical balance with a readability of 0.0001 g. Prepared HAS from the fibrin clot was quantified using a micropipette and stored in 2 ml Eppendorf vials.

Results:
Mean values of PRF and HAS obtained in the study were 2.0089 ± 0.844 g (ranged between 0.0 g and 3.968 g) and 1.540 ± 0.552 ml (ranged between 0.00 and 3.500 ml), respectively. The amount of PRF and HAS obtained were significantly higher in non-diabetic patients (mean 2.3093 g and 1.743 ml, respectively) as compared to diabetic patients (mean 1.5762 g and 1.266 ml, respectively). Results suggested a significant correlation between HbA1c level and quantification of PRF (P=0.007) and HAS (P=0.037), whereas no correlation was observed between HbA1c levels and hematologic, lipid, and demographic parameters.

Conclusion:
Within the limitation of the present study, it can be concluded that a significant correlation exists between the HbA1c level and quantification of PRF and HAS.

Published: July 2023

ABSTRACT

Introduction:
There are numerous chances for pulpal irritation during the placement of a crown on a tooth. This study’s goal was to find and examine the variables that influence the prevalence of routine root canal therapy after the teeth were restored with full coverage crowns.

Methods:
The hospital records were retrospectively evaluated from 2000 to 2010 for a decade. The demographics as well as the various variables that caused for the intervention with the root canal therapy for the teeth with the full crowns were evaluated. The values were compared for the significance.

Results:
The total number of the teeth that were finalized in the study was 4308. Of the total teeth that were treated with full coverage crowns, 50% were metal ceramic, 42% were full ceramic, and 9% were full metal crowns. After 10 years, possibility that every tooth with a crown would survive was 91%. The most frequent adverse incident was the intervention with the RCT. Metal ceramic crowns had poor survival rates and needed the maximum intervention. Younger age-group had least survival rate than the older age-groups.

Conclusions:
Endodontic therapy is unlikely to be necessary after crown installation. As the patient’s age declines and all-ceramic or PFM crowns are used, this risk rises.
Comparison of the Bleached and Non-Bleached Teeth for the Adhesive Boosters for the Orthodontic Bonding: An Original Research
Authors: Deepak V Arun , Kovelakar Ekavenika , Chacko Prince K. , Kandikatla Pradeep , Kumari Lalima , Varma Praveen K. 
Published: July 2023

ABSTRACT

Introduction:
The bleaching of the teeth is known to reduce the bonding of the orthodontic brackets. Hence, this in vitro study was piloted to analyze if there was any variance between the teeth that were and were not bleached when the adhesive boosters were used and for its effect on the shear bond strength.

Materials and Procedures:
Hundred premolars (maxillary) that had been excised were randomly split into two groups: bleached teeth and unbleached teeth. The bleaching agent was gel composed of 22% carbamide peroxide. Maxillary premolar brackets were bonded, and each group was subdivided as control and adhesive booster Enhance LC groups. A universal testing device was used for debonding. The SBS thus recorded was compared for the subgroups and groups.

Results:
Significant variance was obtained for between the groups and between the subgroups. Higher bond strength was for the non-bleached teeth than the bleached teeth and was seen in the adhesive booster subgroup than the control group.

Conclusion:
In summary, adhesive boosters dramatically raised the shear bond strength of teeth irrespective of the bleaching. Further in vivo studies are suggested.

Published: July 2023

ABSTRACT

Introduction:
Achieving a correct occlusion depends heavily on the axial inclination of the teeth, particularly the maxillary anteriors, which have the longest crowns. This study, which expanded the use of angular measures to the mandible, was created to determine the prevalence of adversely angulated canines using orthopantomograms.

Methods:
A sample of 200 people between the ages of 18 and 25 was chosen and separated into two groups based on the degree of crowding; one group served as the control group while the other, which experienced severe, crowding, served as the study group. All of the individuals had their Orthopantomogram and study models taken.

Results:
While canine angulation in controls typically ranges from 85 to 95 degrees, cases of crowding were observed to have angulation as low as 67 degrees and as high as 105 degrees.

Conclusion:
Orthopantomogram can be used to predict canine angulation, with distally and mesially angulated canines occurring at rates of roughly 18% and 37%, respectively.
