Authors: Deshmukh Aishwarya , Poovani Shwetha Kumari , Thumati Prafulla 
Published: July 2024

Aim:
The aim of this study is to evaluate the influence of occlusion on body posture and plantar arch pressure.

Settings and Design:
An Observational analysis to Analyze the Influence of Occlusion on Plantar Pressure and Body Posture.

Materials and Methods:
A total of 30 asymptomatic subjects were selected for the study including 18 females and 12 males from age group 22 years to 28 years with a mean age of 24.83 years. Each subject underwent evaluation of occlusion at MIP using a Digital Occlusal analyzer (T-Scan III). At this point, the subjects were made to stand on a mat scan which consisted of a large postural platform sensor and a computer that displayed the plantar pressure data. The computer connected to the T Scan displayed the occlusal pressure analysis. This was followed by an evaluation of body posture using a posture grid where the photographs were taken and an evaluation of the frontal and lateral photos was done using the APECS – posture analysis app.

Statistical Analysis Used:
Statistical package for social sciences (SPSS) for windows version 22.0 Released 2013, Armonk, N Y: IBM Corp., was used to perform Statistical Analysis. A chi-square test was applied for qualitative variables to find the association. Paired t-test was applied to compare the changes in the quantitative parameters in eye-open and eye-closed conditions. The level of significance was set at 5%.

Results:
As observed from the results, occlusion for 40% of the subjects, where n = 12, was dominant on the right side. Occlusion for 23.3% of subjects, where n = 7, was dominant on the left side. Whereas, for 36.7% of subjects, where n = 11, the pressure distribution was almost equal on both sides. The inclination of body posture for 23.3% of subjects, where n = 7, was towards the right side. The inclination of body posture for 50% of subjects, where n = 11, was towards the left side. And, the inclination of body posture for 26.7% of subjects, where n = 8, was neutral i.e., balanced on the right and left side. Plantar pressure for 6.7% of subjects, where n = 2, was dominant on the right side. Plantar pressure for 36.7% of subjects, where n = 11, was dominant on the left side. Whereas, for 56.7% of subjects, where n = 17, the plantar pressure distribution was almost equal on both sides.

Conclusion:
On correlating the three parameters, it was found that occlusion for most of the subjects dominated on the right side, while body posture and plantar pressure dominated on the contralateral i.e., left side.
Comparative evaluation on surface nanohardness, surface microhardness, surface roughness, and wettability of plant-based organic nanoparticle reinforced polyetheretherketone as an implant material – An in vitro study
Authors: Vidhyasankari N. , John Reena Rachel , Senthilmurugan P. R. , Vishnupriya V. 
Published: July 2024

Aim:
Synthetic inorganic materials are commonly used as reinforcing agents in polyetheretherketone (PEEK) composite, whereas natural organic plant-based reinforcing agents are negligible. Surface hardness, roughness, and wettability are indicative factors of osseointegration behavior to be used as an implant material. This study evaluated micro surface hardness (MSH), nano surface hardness (NSH), surface roughness (SR), and contact angle (CA) of PEEK-Azadirachta indica reinforced at 10 wt%, 20 wt%, and 30 wt%.

Settings and Design:
This was an in vitro study.

Materials and Methods:
Neem (A. indica) leaf nanoparticles were prepared and reinforced with PEEK powder at 10%, 20%, and 30% weight ratios by injection molding. Sixty specimens underwent the microhardness and CA testing using a digital microhardness tester, and CA goniometer, respectively, and later nanoindentation test to analyze the nanohardness and SR.

Statistical Analysis Used:
A one-way ANOVA test with a 95% confidence interval for MSH and NSH, SR, and CA was performed on the samples. A post hoc Bonferroni test was conducted (α = 0.05) to compare the groups.

Results:
There was a significant increase in nanohardness (P = 0.000) with zero difference in microhardness (P = 0.514). The addition of 10 wt%, 20 wt%, and 30 wt% nanoparticles increased the SR value of the pure PEEK from 273.19 nm to 284.10 (3.99%), 296.91 (8.68%), and 287.54 (5.24%), respectively. In the analysis of the CA, CA 20% shows the lowest angle (63.69) with the highest for control specimens (82.39). There is an increase in the PEEK composite SR with a decrease in CA.

Conclusions:
The addition of plant-derived nanoparticles into the PEEK matrix has a significant impact on the hardness and hydrophobicity enhancing cell growth and osteoblastic differentiation during osseointegration of dental implants.
Precise jaw relation recorder: An innovative device for prosthodontic rehabilitation
Authors: Kumar C. Dhinesh , Selvaraj Sunantha , Raju Ramesh , Mohan Jayashree 
Published: July 2024

Background:
The orchestration of jaw relations in edentulous scenarios poses a significant challenge, demanding acumen, and expertise from the clinician. A myriad of devices, substances, and methodologies are employed to gauge the transverse, vertical, and horizontal spectrums of jaw relations. Traditionally, a synthesis of assorted devices and techniques has been requisitioned to chronicle the spatial dynamics between the maxilla and mandible. Yet, the absence of a solitary apparatus capable of concurrently documenting the triad of jaw relations has been a notable lacuna in prosthodontic rehabilitation.

Purpose:
This discourse expounds on an innovative contrivance, termed the Precise Jaw Relation Recorder. This pioneering instrument is adept at capturing the tripartite jaw relation processes: the occlusal plane's alignment in parallelism to the ala-tragus line, the vertical dimension at repose, and the occlusion as well as the centric relation. The device's strategic utility lies in its ability to facilitate the creation of prostheses that are not only functionally superior but also aesthetically more pleasing.

Conclusion:
Its implementation is a stride toward refining the accuracy of prosthodontic outcomes, thereby elevating the standard of patient care in dental practice.
Effect of titanium dioxide and zirconium dioxide nanoparticle incorporation on the thermal conductivity of heat-activated polymethylmethacrylate denture base resins: An in vitro experimental study
Authors: Adhershitha A. R. , Viswambharan Prasanth 
Published: July 2024

Aim:
The aim is to determine thermal conduction by heat-activated polymethylmethacrylate (PMMA) infiltrated with 1 weight% Titanium Dioxide (TiO2) and 1 weight% Zirconium Dioxide (ZrO2) nanoparticles and to compare with that of conventional PMMA.

Study Setting and Design:

In vitro experimental study.

Materials and Methods:
Eighteen disc shaped specimens with a thickness of 5 mm and diameter of 50 mm, were fabricated and grouped according to the material used: Group B1 (resin infiltrated with 1 weight% TiO2), Group B2 (resin infiltrated with 1 weight% ZrO2), and Control Group B3 (heat-activated conventional PMMA resin). Disc-shaped specimens were analyzed for thermal conductivity using “modified guarded hot plate apparatus” in the thermal lab of the Indian Space Research Organisation.

Statistical Analysis Used:
One-way ANOVA followed by Tukey’s post hoc test was used to compare the arithmetic means of all three groups.

Results:
A statistically significant difference was noted among all three groups. Group B2 had the maximum thermal conductivity, followed by Group B1. Thermal conductivity was the least for Group B3. A post hoc comparison revealed that the difference was significant between Group B2 and Group B3.

Conclusion:
Nano ZrO2 addition in PMMA increased its thermal conductivity. There is evidence that it improves its mechanical properties as well. Hence, Nano ZrO2 addition in PMMA is highly recommended. Nano TiO2 addition in PMMA did not provide any significant advantage in terms of thermal conductivity, but its addition in PMMA is justified because of its mechanical and antimicrobial properties.

Published: July 2024

ABSTRACT

Background:
Orthodontic retention protocols are crucial for maintaining treatment stability post-orthodontic treatment. However, the optimal retention strategy remains debated.

Methods:
A retrospective analysis of patient records from a tertiary orthodontic center over 5 years was conducted. Variables, including retention protocols employed, duration of retention, and treatment stability, were weighed.

Results:
Fixed retainers were the most commonly utilized retention protocol, followed by removable retainers and combination methods. Although the incidence of treatment relapse appeared higher among patients with removable retainers, the difference did not reach statistical significance. Combination protocols demonstrated comparable treatment stability to fixed retainers.

Conclusion:
This research gives understanding of the effectiveness of orthodontic retention protocols in a tertiary center setting. While fixed retainers remain widely used, removable retainers and combination methods also show promise in maintaining treatment stability. Addressing patient compliance issues and optimizing retention strategies based on individual patient needs are essential for enhancing treatment outcomes.

Published: July 2024

ABSTRACT

Objective:
The purpose of this in vitro investigation was to assess the effectiveness of various gutta-percha retrieval methods in endodontic retreatment.

Methods:
Five groups were randomly allocated to extract human teeth that had already had root canal therapy: manual files, rotary tools, heat, solvents, and ultrasonics. By evaluating the amount of filling material still present, gutta-percha clearance was quantitatively examined, and root canal cleanliness was qualitatively appraised. To compare the effectiveness of retrieval approaches, statistical analysis was done.

Findings:
Hand files, heat, and solvents were less effective than rotary devices and ultrasonics at removing gutta-percha (P < 0.05). A quantitative investigation showed that the groups using rotary instruments (0.87 mm) and ultrasonics (0.68 mm) had much less gutta-percha left. The qualitative evaluation revealed that rotary instruments (2.12) and ultrasonics (2.45) had greater cleaning ratings compared to other methods.

Conclusion:
In conclusion, gutta-percha can be effectively removed during endodontic retreatment by using rotary tools and ultrasonics, which provide both quantitative efficiency and qualitative purity. The implementation of sophisticated retrieval procedures to maximize treatment results in clinical practice is supported by these findings.

Published: July 2024

ABSTRACT

Background:
Because of its ease and visual attractiveness, clear aligner therapy has grown in popularity as an orthodontic treatment option. On the other hand, the results of therapy may be impacted by attachment wear. Comparing attachment wear in three distinct clear aligner systems—System A, System B, and System C—was the goal of this investigation.

Methods:
The research comprised 60 individuals receiving clear aligners as part of their orthodontic treatment. Depending on whatever clear aligner system was being utilised, the patients were split into three groups. Attachment wear was evaluated using a standardised scoring method regularly. The various systems’ attachment wear was compared using statistical analysis.

Results:
Compared to Systems B and C, System A showed less attachment wear. There were notable variations in attachment wear ratings between the systems. System C’s attachments had the most wear, whereas System A’s attachments had the least.

Conclusion:
Different clear aligner systems showed varying degrees of attachment wear, with System A exhibiting the least amount of wear. To maximise treatment procedures and guarantee treatment efficacy and longevity in clear aligner therapy, it is vital to comprehend attachment wear patterns.

Authors: Singh Shiwangi , Taide Ankit A. , Kaur Jasmine , Panda Sanjukta , Srilakshmi Donka , Nelson Anish , Baig Fawaz A. H. 
Published: July 2024

ABSTRACT

Objective:
Comparing fixation procedures for managing naso-orbito-ethmoidal (NOE) fractures.

Methods:
Group A (plate and screw fixation), Group B (Kirschner wire (K-wire) fixation), Group C (absorbable plate and screw fixation), and Group D (No fixation) were formed from 120 NOE fracture patients. The facial injury severity scale, visual analogue scale, CT scans, and clinical examination examined functional and cosmetic outcomes, complications, and postoperative stability.

Results:
The study found that plate and screw fixation (Group A) had the highest stability and aesthetic results, followed by absorbable plate and screw fixation (Group C). Conservative management (Group D) had the worst outcomes, while K-wire fixation (Group B) had good results but more complications. Results showed substantial differences in functional, aesthetic, complications, and postoperative stability between groups (P < 0.05).

Conclusion:
Plate and screw fixation is the most successful and dependable approach for treating NOE fractures, with superior functional and aesthetic outcomes, reduced complications, and higher postoperative stability than K-wire fixation, absorbable plate and screw fixation, and conservative care. Absorbable plate and screw fixation may function instead of metal. Conservative care should be rare. Larger multicenter randomized controlled trials should corroborate these findings.

Authors: Gami Nihar , Shukla Krutarth , Patel Ishan , Gandhi Nayan Manish 
Published: July 2024

ABSTRACT

Background:
Significant morbidity and death are linked to sleep apnea (SP), a prevalent sleep disease. For successful management, it is essential to comprehend its prevalence and the risk factors that are linked with it. The purpose of this study was to look at the prevalence of SP in a large patient group that was visiting a tertiary care facility and to discover risk variables that are connected with it.

Methods:
500 volunteers were gathered from a tertiary care center to participate in cross-sectional research. Polysomnography, clinical evaluations, and standardized questionnaires were utilized to diagnose SP and gather pertinent information. A statistical study was conducted to evaluate the correlation between different risk factors and SP.

Results:
35% of people had SP, with men between the ages of 40 and 60 having a greater frequency. It has been determined that smoking, obesity, and high blood pressure are important risk factors for SP. Compared to those with mild or moderate SP, individuals with severe SP had greater rates of smoking, hypertension, and obesity (BMI > 30).

Conclusion:
This study emphasizes how common SP is in tertiary care settings and how it is linked to smoking, obesity, and hypertension. Improving patient outcomes and lessening the impact of SP need early identification and management techniques that address these modifiable risk factors.

Published: July 2024

ABSTRACT

Introduction:
Oral health related quality of life (OHRQoL), locus of control, dental health as assessed by oneself and oral health situation have all been the subject of several research, but none of them have yet been investigated in combination.

Materials and Methods:
This cross-sectional study was carried out on 525 nursing students to investigate these ideas. The Oral Health Impact Profile-14 (OHIP-14) scale was employed to evaluate the standard of living associated with oral health.

Results:
Both chance participants and group internals reported having good OHRQoL. Nursing students in the internals group accurately assessed the deteriorated aspect of their self-reported oral health. However, it was found that participants from the chance locus and powerful others were unable to accurately rate the decayed component (P < 0.05).

Conclusion:
Internal nursing students had the highest OHRQoL, followed by random and influential students. Individuals from locus internals and random gave accurate ratings of their dental deterioration.

Authors: Gonzaga Zarinah Garcia , Castillo-Cheng Maria Rosario , Macalintal Joseph Carl , Caro-Alquiros Lizzette , Causin Stephanie , Estanislao Grace Lynn Santos 
Published: July 2024

BACKGROUND:
To reduce maternal morbidity and mortality associated with hypertension, standards for maternal safety and efforts to implement a structured team approach have been undertaken. Following the formulation of a policy document, a maternal safety bundle was developed. The implementation of bundle components including eclampsia kits, clinical pathways, and educational module occurred in phases due to pandemic restrictions. An eclampsia kit and clinical pathways were implemented in 2020. An online lecture was launched in 2021 followed by in-person eclampsia simulation workshop beginning 2022.

OBJECTIVES:
This paper aims to report the early outcomes of a severe preeclampsia and eclampsia maternal safety bundle implementation in a private hospital between 2020 to 2023.

MATERIALS AND METHODS:
Demographic information, posttest knowledge assessment and pre- and post- eclampsia workshop confidence scores were recorded. Structure, process, and outcome measures were determined. Descriptive statistics were used for participant demographics and score percentages. Paired t-Test with a significance level of P<0.05 was used to compare the pre- and post-simulation confidence scores. Summary data for outcome and process metrics were manually calculated. Summary categorical data was used for structure metrics.

RESULTS:
Two hundred eighty-eight (288) participants completed the online didactic lecture. Average posttest knowledge assessment score was 88.1%, 88.88%, and 82.6% from 2020 to 2023. Ninety-nine participants completed the eclampsia simulation workshops. Mean post-simulation confidence scores were greater than mean pre-simulation confidence scores (42.3 vs. 39, p=0.0259 in 2022 and 41.975 vs 36.65, P=0.0035 in 2023). There is 100% compliance with timely management of severe hypertension and eclampsia prevention and a decreasing trend in hypertension related severe maternal morbidity rates.

CONCLUSION:
A severe preeclampsia and eclampsia maternal safety bundle is a feasible quality improvement initiative that promotes peer learning, strengthens clinical competencies, and improves access to emergency resuscitation supplies. The results of this program evaluation may serve as a framework for implementing quality improvement initiatives on maternal safety.
A sonographic evaluation on agreement and time efficiency of fetal central nervous system biometry using semi-automated five-dimensional ultrasound versus standard two-dimensional ultrasound in a Philippine tertiary hospital
Authors: Caro-Alquiros Lizzette Reduque , Gonzaga Zarinah Garcia , Quinio Irene B. 
Published: July 2024

BACKGROUND:
Proper assessment and efficient diagnosis of central nervous system anomalies is essential in antenatal surveillance of pregnant patients. These anomalies are usually associated with genetic syndromes or severe malformations requiring timely intervention and antenatal counseling of the expectant couple.

OBJECTIVE:
The study aims to evaluate the agreement of cranial biometric measurements and to determine if there is a significant difference in the time needed to complete the evaluation using standard 2D and semi-automated 5D ultrasound.

METHODS:
An analytical cross-sectional study was employed on 93 women who underwent pelvic ultrasound scans from August to October 2022 in a tertiary hospital. Basic biometric fetal central nervous system (CNS) measurements were acquired using 2D ultrasound followed by 5D CNS ultrasound. Bland-Altman plots were used to evaluate the agreement of the measurements obtained. The difference in the time to completion was determined using independent t-test.

RESULTS AND CONCLUSION:
Our study found that 5D CNS ultrasound measurements showed 96.8% agreement with 2D ultrasound in 90 out of 93 fetuses. The 5D CNS ultrasound takes a shorter time of 90 seconds (s) to completion in comparison to 99 s using the 2D method (p=0.076). Upon stratification of the study population per trimester, in the second trimester, it took 76 s with 5D CNS vs 89 s with 2D, resulting to a statistically significant 13-second difference (p=0.044). In the third trimester, 5D CNS took 105 s vs 108 s with 2D (p=0.614). The time to completion of the scan using this technology is faster when used for second trimester pregnancies but could be affected by fetal-dependent and operator-dependent factors. Therefore, application of this new technology has the potential to improve workflow efficiency after the necessary training on 3D sonography and 5D CNS ultrasound software.
