Published: July 2022

Introduction:
To thoroughly plan and execute any dental treatment, the anatomy of the dental root canals is of prime significance. Hence, in this systemic review, we intend to evaluate the cone beam computed and micro-computed tomographic presentations of the root canal morphologies of the secondary teeth.

Materials and Methods:
We conducted the search for the data from the online sources such as the “EMBASE,” “Pubmed,” “Scopus,” and other sources. Only human studies were collected. Terms searched were cone beam computed tomography (CBCT), micro-computed tomography, permanent teeth, and root canal morphology. The data extraction and meta-analysis were based on the PRISMA guidelines.

Results:
A total of 170 studies were initially considered for the study. After the application of the inclusion and the exclusion criteria, only ten studies were qualified for the study. In 2 studies, the comparison was done between the conical beam and the microtomograhic views for assessing the root canal anatomies. There were, however, three studies that did not conclude any significant relation between the two imaging systems. When the risk of bias was calculated for the ten studies, there were only low and moderate for the ten included studies. The pooled prevalence among the genders were 21.4% (14.0%–24.6% confidence interval [CI] 95%) and 25.3% (20.0%–30.7% CI 95%), respectively, with high heterogeneity values (= 99.30% and 98.50%, respectively), but no statistical significance (P > 0.05).

Conclusion:
Both the imaging systems CBCT and the microtomography can be used with accuracy in the evaluation of the anatomic variations of the human root canal. However, a definition is dependent on the voxel size.

Published: July 2022

Background:
Oral health is an effective unit of general health. Dental caries and periodontal diseases are considered to be the major diseases present in modern times. Over the decades, the idea of maintaining effective oral health and interest in oral health prevention measures has diminished; thus increasing the cost of health care.

Aims and Objectives:
This study aims to estimate the household expenditure on oral health care among people residing in Kerala, India.

Materials and Methods:
Five hundred participants were surveyed who were residents of Kerala. A self-administered questionnaire that was tested and validated was used to assess the cost of oral health care. Data collected were analyzed using software for IBM SPSS version 23 for Windows (New York, USA).

Results:
Of 500 people, 37% are men and 63% are women. 100% of people reported using a toothbrush as an oral hygiene aid. 65% of households reported changing toothbrush for 3 months or more, while 35% of families changed for 1 month or less. Significant statistically weak correlation was observed when education, employment, and income were compared to the annual expenditure on dental care. Furthermore, there has been a moderately strong correlation observed between the socio-economic status of families and the annual cost of dental care.

Conclusion:
People should be aware of preventive oral hygiene aids, and appropriate policies should be formulated which will ultimately result in decreased expenditure on a curative aspect of the dental disease.

Published: July 2022

Introduction:
The success of the prosthetic rehabilitation is a factor of the periodontal reactions. Hence, in the current study, we aim to assess bone loss in the osseointegrated implants posttreatment by the cone beam computed tomography (CBCT) imaging.

Materials and Methods:
We conducted a prospective clinical observational study among 50 subjects who received mandibular dental implants for the replacement of the single lost anterior tooth. The follow-up was done at 1 week, 2 weeks, and after 6 weeks. The bone loss around the implant was noted by imaging with CBCT. The values were compared and analyzed statistically.

Results:
We observed a significant variation among the genders and the age groups. The mean bone loss around the implants was statistically significant for the different time intervals (P = 0.001).

Conclusion:
Significant bone loss was noted in the first few weeks after implantation. Care should be focused in the initial posttreatment phase to eliminate the factors aggravating the periodontitis.

Published: July 2022

Introduction:
The students pursuing professional studies such as medicine and dentistry have to endure a lot of stress. Hence, we evaluated the prevalence of stress and coping disorders among dental students.

Methods:
We conducted a questionnaire-based online survey study among 100 dental students of 1–4 years. The survey was based on the “modified General Health Questionnaire (GHQ-12; Goldberg and Williams, 1988).” The scores were analyzed for the statistical connotation, keeping P < 0.05 as significant.

Results:
We observed that over half of the dental pupils felt stressed. The dental students resorted to “Destructive coping mechanisms.” Less than 15% of students sought medical and psychiatric counseling. The mean GHQ was 12 ± 1.7.

Conclusions:
Psychological strength is a prerequisite for good health and better performance in the studies as well as for the practice. There is an urgent need to focus on the mental health of the students specifically in the medical and dental fields.

Published: July 2022

Aim:
This study aims to compare the retentive capacity of two attachment systems after manual thermocycling.

Settings and Design:

In vitro study and Comparative trail.

Materials and Methods:
An edentulous mandibular Polymethyl Methacrylate model was fabricated to receive the overdentures with the two attachment systems to be compared. Two dental implants were placed in the predetermined right and left mandibular canine regions of the model. A total number of eight overdentures, four per group, were fabricated over the two implants with two attachment systems to be compared; Bar and clip attachment system (Group-1) and Locator attachment system (Group-2). All the overdentures were subjected to 5000 alternating thermal cycles using manual thermocycling. Then the samples were subjected to 100 vertical pulls each in the anterior and posterior regions using a universal testing machine and the mean retentive forces were calculated for each sample in the anterior and posterior regions, respectively.

Results:
The mean retentive forces after 100 vertical pulls, were calculated and tabulated for each sample in the anterior and posterior regions separately. Then, the cumulative mean of the anterior and the posterior regions were calculated for each group. The cumulative mean retentive forces of both the attachment groups were-Group-1 (Bar and clip attachment system) = 27.87 N ± 4.01 and Group-2 (locator attachment system) = 18.85 N ± 2.50 with a P value of 0.021. This difference was found to be statistically significant.

Conclusion:
Within the limitations of the present in vitro study, the bar and clip attachment system offered better retention than the locator attachment system.

Published: July 2022

Introduction:
The bone pathology-giant cell tumor (GCT) is a locally aggressive and recurrent lesion. A bisphosphonate-zoledronic acid (ZA) has been known to lower the recurrence and resorption in similar bone lesions. Hence, we evaluated the effectivity of the ZA for the GCT of the proximal tibia.

Materials and Methods:
We piloted a prospective clinical observational study. We included 100 subjects with GCT, who were divided into two equal groups of case (given ZA) and control (no ZA). The histopathological features and the recurrence rates along with other findings were compared with P < 0.05 deliberated as significant.

Results:
We observed that for in the case group, calcification and fibrosis that were beneficial were observed. Reduced giant cells and lower recurrence rate are seen in the case group. No significant variation in the functional outcome was seen between the groups.

Conclusions:
ZA was shown to have beneficial effect on the outcome for the treatment of the GCT.

Published: July 2022

Aim:
The aim of the current study was to evaluate the radicular dentin defect during retreatment employed diverse NiTi hand and rotary retreatment file systems.

Materials and Methods:
Eighty mandibular premolars with a single root and root canal that were recently extracted were gathered and stored. The premolars were subject to decoronation at cementoenamel junction (CEJ) beneath irrigation with water to attain a uniform radicular length of 16 mm. Gutta-percha cones were covered with sealer and introduced into the root canal up to the working length. Eighty teeth were allocated at random into four groups with each group consisting of 20 samples. Group I: Control, Group II: EdgeFile XR retreatment rotary files, Group III: ProTaper Universal retreatment files, and Group IV: MTwo retreatment files. Under constant water cooling, the roots were cut flat with a diamond disc at apical third (3 mm), middle third (6 mm), and cervical third (9 mm) points. Stereomicroscope was employed to visualize the sections below × 20 magnification.

Results:
A statistically significant difference was noted among the groups with respect to the formation of radicular dentinal defects at 3 mm (P < 0.01) and 6 mm (P < 0.001), while the sections at 9 mm did not exhibit any statistically significant difference (P > 0.598).

Conclusion:
Despite the limitations in this study, it was concluded that all the evaluated file systems efficiently eliminated root canal filling during the retreatment. In addition, it was noted that the EdgeFile XR group exhibited fewer root dentin defects in comparison with the MTwo and ProTaper Universal group of files.

Published: July 2022

Introduction:
Establishing an accurate vertical dimension at occlusal (VDO) is a challenge. Hence, we aim to find the association between the VDO and the Thumb Length (TL).

Materials and Methods:
We piloted an observational study by evaluating the VDO and the TL among the Dravidian and Aryan ethnicities with 200 volunteers. The comparisons were made applying the “linear regression analysis” to find the correlation of both.

Results:
We observed that a strong and positive relation was established for the two parameters of VDO and TL for both the ethnicities.

Conclusion:
We can suggest from our study that the thumb length can be used as an aid for the occlusal vertical dimension estimation.

Prevalence of Candida among Denture Wearers and Nondenture Wearers
Authors: Manikandan Saranya , Vinesh E , Selvi D. Thamarai , Kannan R. Kamala , Jayakumar Arun , Dinakaran J 
Published: July 2022

Introduction:
A denture wearer is highly prone to develop Candida-associated denture stomatitis (CADS) due to the conversion of the normal oral commensal Candida spp. into a pathogen under favorable conditions. Immuno-compromised status, trauma from the prosthesis, other systemic conditions, and improper maintenance of the dentures by the patient are few of the causative agents which turn the oral balance into an unhealthy and unsuitable foundation for the wearing of the prosthesis.

Objective:
The objective of this study was to compare subjects wearing complete dentures and nondenture wearers regarding Candida isolates associated with disease and colonization among the different age groups.

Methodology:
A cross-sectional study was conducted among 60 subjects, 30 wearing complete dentures (Group-A) and 30 nondentures wearers (Group-B), were matched for gender, race, and age. The unstimulated saliva sample was collected and cultured in CHROMagar using standard protocols.

Results:
The mean value of the candidal colony-forming units with respect to Group A is Candida Albicans 0.36 ± 2.008, Candida krusei 0.27 ± 1.061, P value Group B: C. albicans 0.73 ± 2.196, C. krusei 0.36 ± 1.084. There was a significant relation between denture wearers and heavy growth of C. albicans and C. krusei in saliva culture with a P value of P-0.054 and P-0.036, respectively.

Conclusions:
These results indicate that denture wearers with oral Candida had a higher prevalence of CADS. Patients with removable prostheses should be informed about the importance of proper prosthesis and personal hygiene since dentures and age-related immunosuppression are both well-known risk factors associated with candidiasis development, the presence of yeast, even in healthy denture wearers, should be considered a risk factor for denture stomatitis that increases with the duration of denture use.

Published: July 2022

Objectives:
The objective is to evaluate the efficacy of LuxaCore, Photo Core, and Core Max II on fracture resistance of endodontically treated teeth restored with ParaPosts and fiber-reinforced composite (FRC) posts.

Materials and Methods:
Ninety extracted mandibular first premolar teeth were randomly grouped into nine different groups with ten samples in each. I-FRC posts, II-FRC with Photo Core, III-FRC with LuxaCore, IV-FRC with composite core, V-FRC with Core Max II, VI-para Post (PP), VII-PP with Luxa core, VIII-PP with photo Core, IX-PP with Core Max II were compared for fracture resistance.

Results:
The mean fracture resistance (Newton) in group I was 452± 61.5, in group II was 412.6± 42.4 (higher from group I to group V), and lower in group VI to group IX (288 to 246.5). The mean fracture resistance of group II to V was 380.1±72.1 and group VI to IX was 62.8±70.6. The difference was statistically significant (0.001).

Conclusion:
FRC posts exhibited higher fracture resistance as compared to ParaPosts, and fracture resistance was not dependent on the type of material used.
