Published: March 2023

Background:
Recently, new calcium silicate-based materials have been introduced as root-end filling material which offers improved color stability and handling characteristics, while exhibiting physical and chemical properties comparable with mineral trioxide aggregate (MTA).

Aim:
The purpose of this study was to compare the sealability of 3 calcium silicate-based materials - MTA Plus (Prevest Denpro, India), Biodentine (Septodont, St. Maurdes Fossés, France), and TotalFill BC RRM (FKG, Brasseler, Savannah, USA) in a simulated open apex model.

Materials and Methods:
Thirty-two recently extracted human maxillary anterior teeth with single, straight root canals were selected and after establishing the working length, canals were prepared by Protaper Gold system up to size F3. The apical end was resected at 3 mm to simulate an open apex. Prepared roots were divided into groups according to the root repair materials – MTA (Prevest Denpro, India), Totalfill Bioceramic Root Repair Material (FKG, Brasseler, Savannah, USA), and Biodentine (Septodont, St. Maurdes Fossés, France). The apical plug of the root filling material was placed in the orthograde direction and a glucose leakage model was used to study the sealability of the materials.

Results:
All three materials showed more leakage at 14 days than at 7 days, however, there was no statistically significant difference between them.

Conclusion:
All three bioceramic materials exhibited equal amounts of apical leakage at 7 and 14 days.

Published: March 2023

Background:
In completely edentulous patients, it is necessary to replace the teeth with at most esthetics and comfort with less patient strain.

Aim:
The current retrospective study was done to find the relationship between the intercondylar distance and intercanine distance of the mandible by obtaining the ratio using an orthopantomogram (OPG) for lower anterior teeth selection in completely edentulous patients.

Materials and Methods:
The OPG of 500 subjects was selected randomly. The OPGs were taken using the Sirona Orthophos XG machine and exposed for 14.1 s at 64 kvp, 8 mA. Then, the intercondylar distance and mandibular intercanine distance were measured from the soft copy of the OPG using the software “Sidexis.” The required measurements were taken digitally from the OPG using the software “Sidexis” in millimeters (mm). The SPSS software version 22.0 was used for statistical analysis.

Results:
Pearson correlation coefficients (r) displayed a significant positive association between the intercondylar distance and intercanine distance of the mandible (r = 0.42; P = 0.0002). The correlation between intercondylar width and mandibular intercanine width was significant and positive for men (r = 0.26, P = 0.0003) but negative for women (r = −0.41, P = 0.0001). The ratio between the mean intercondylar width and the mean intercanine width was 1:4.90.

Conclusion:
The mandibular intercanine distance and the intercondylar distance have a positive and significant association. The ratio obtained in this study was 1:4.90 between the mandibular intercanine distance and the intercondylar distance that could be employed for the choice of mandibular anterior teeth.

Effect of two different antifibrinolytic agents on platelet-rich fibrin
Authors: Ponnusamy Vishnu , Nalini H. Esther , Devi R. Renuka , Raja Nivetha 
Published: March 2023

Background:
Platelet-rich fibrin (PRF) is a potent autologous regenerative material used in periodontal regeneration. PRF collapses easily into the periodontal defect due to its faster resorption rate and lesser rigidity. The degradation time of PRF has a direct impact on the clinical outcome.

Aim:
This study aimed to compare and analyze the effect of two different antifibrinolytic agents on the degradability of PRF membranes.

Materials and Methods:
Twenty-one PRF membranes were randomly divided into three groups: Group 1 – Conventional PRF obtained by adding normal saline (Control), Group 2 – PRF obtained by adding 200 mg tranexamic acid (TXA), and Group 3 – PRF obtained by adding 250 mg epsilon aminocaproic acid (EACA). After storing at room temperature in normal saline, PRF membranes were retrieved at 1st, 2nd, and 3rd weeks and the percentage of remaining weight was calculated. ANOVA is used for the statistical comparison of the data between groups.

Results:
In comparison to the baseline, the mean PRF weight was decreased in all groups in the 1st, 2nd, and 3rd weeks. In the 1st, 2nd, and 3rd weeks, the mean percentage of the remaining weight of PRF membrane in Group 1, Group 2, and Group 3 were 69.53 ± 12.96, 36.23 ± 9.28, and 17.43 ± 4.75 respectively. The statistical significance with the percentage of the remaining weight of the PRF was obtained in 3rd week with a P = 0.029.

Conclusion:
TXA efficiently delayed the degradability of the PRF membrane compared to EACA under experimental conditions.

Timely diagnosis and management of this syndrome are warranted. The dental surgeon has a prime role in diagnosing the same and halting the progression of gingivitis to periodontitis and referring the patient to appropriate specialists for effective and timely management of the same.

Patient Concerns:
In this case report, a 17-year-old patient had reported with the chief complaint of spontaneous bleeding from gums and swollen gums since birth, and blackish pigmentation of the skin.

Diagnosis:
On examination, the patient had poikiloderma, photosensitivity, gingival fragility, and skin atrophy suggesting a diagnosis of Kindler syndrome.

Interventions:
Oral prophylaxis was done for the patient on several sittings and the patient was on continuous follow-up for 2 years. Dermatology and urology opinions were sought and advice was followed.

Outcomes:
The patient had complete regression of spontaneous gingival bleeding and oral hygiene had also become satisfactory.

Lesson:
Prompt diagnosis of the disease with appropriate and early intervention by a dental surgeon could definitely stop the disease progression.
Enamel island technique and nonrigid connectors
Authors: Bahri Maj Rahul , Prakash Poonam 
Published: March 2023

Rationale:
Fixed denture prosthodontics is a commonly practiced treatment option for rehabilitation of partially edentulous clinical conditions. Certain local and systemic factors contraindicate utilization of implant therapy. Long edentulous span, pier abutment, distal abutments, and intersegment prosthesis extending from one sextant to another are a few challenging situations due to altered biomechanics and require modification in treatment planning to achieve optimum outcome.

Patient Concerns:
A 37-year-old male patient reported with difficulty in mastication due to partially edentulous mandibular arch.

Diagnosis:
Based on clinical features, a diagnosis of Class II partially edentulous mandibular arch was made.

Intervention:
Rehabilitation of partially edentulous mandibular arch was done using customized semiprecision attachment.

Outcomes:
Recall appointments were scheduled at 48 h, 1 week, 1 month, and 3 months and the patient was found to be satisfied with the prosthesis.

Lessons:
Semiprecision attachment is a viable modality that is used in rehabilitation of pier abutment situations. It protects the abutment from unwanted leverage forces and ensures longevity of the restoration.
1D crustal structure of Albania region
Authors: Dushi Edmond Dhimitraq , Havskov Jens 
Published: March 2023

A new crustal 1D layered model for Albania has been determined. The data used consist of P and S readings from 108 evenly distributed and well located earthquakes using the Albanian Seismic Network and nearby seismic stations. The method used was to relocate the data using many thousand models, which were varied in a systematic way in a wide range around a start model determined from currently available models. The model with the lowest average travel time residual RMS was then selected as a final model. Tests with synthetic data showed this to be a robust method. With the dataset, the average RMS was reduced from 0.69s, using the current model, to 0.56s using the start model and to 0.49s using the final model. The new hypocenters were also found to be closer to a set of well located ISC hypocenters than the original locations. The final model found is: Depth to interface (km) P-velocity (km/s) 0 5.5 12 6.0 23 6.3 41 7.7 with a Vp/Vs=1.81. This final model is different from the currently used model in Albania and should therefore represent a significant improvement for earthquake location.
Metal Ion Sensing by BAPTA: Investigation Using 1H NMR Spectroscopy
Authors: Adoni Sunayna , Mologu Trivikram , Igumenova Tatyana 
Published: March 2023

Many biological macromolecules rely on metal ions to maintain structural integrity and control their regulatory function. In biological fluids, detection and identification of metal ions requires sensitive analytical tools with clear readouts. In this work, we sought to investigate the potential of solution Nuclear Magnetic Resonance (NMR) spectroscopy to analyze metal ion solutions and mixtures. To enable 1H NMR detection, we prepared the complexes of eight metal ions with the chelating agent, 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (BAPTA). The 1H NMR spectra were collected for BAPTA samples as a function of metal ion concentrations. The analysis of NMR data revealed that all metal ions with a notable exception of Mg2+ bind BAPTA with high affinities and form complexes with 1:1 metal-to-chelator stoichiometry. Both methylene and aromatic regions of the BAPTA 1H NMR spectra experience significant changes upon the metal ion complex formation. We identified the spectroscopic signatures of trivalent and paramagnetic ions and demonstrated that the binary Zn2+/Pb2+ metal ion mixture can be successfully analyzed by NMR. We conclude that complexation with BAPTA followed by the 1H NMR analysis is a sensitive method to detect and identify both nutritive and xenobiotic metal ions.

Authors: Mugumya Duncans , Karooro Emmanuel , Mwesigye Adrian Rwekaza 
Published: March 2023

Purpose: Globally, parents' engagement in their children's education has been found to result in improved academic success. This study investigated the prediction effect of parental engagement on students’ academic performance in government grant-aided secondary schools in Sheema District, South Western Uganda.
Methodology: The study used quantitative approach employing cross-sectional survey design. Participants included senior four students, parents of senior four students, and teachers teaching in senior four class. The participants were selected using simple random sampling technique. Data on parental engagement and learners’ academic performance were collected using a 5-point Likert scale questionnaire.
Findings: Study results indicated a statistically significant effect of parental engagement in provision of basic needs (t = 5.242, p< .05), academic communication (t = 6.116, p< .05), decision making (t = 5.834, p< .05), infrastructural development and maintenance at school (t = 5.525, p< .05), provision of conducive learning environment (t = 6.819, p< .05), provision of adequate learning resources (t = 6.167, p< .05) on learners’ academic performance. However, the combined effects of parental engagement aspects did not significantly predict learners’ academic performance. The results imply that parental engagement in learners’ educational pursuit should be encouraged so as to enhance learners’ academic performance.
Recommendation: It is therefore recommended that school programmes that can compel parents to participate in educational activities should be deliberately instituted so as to enhance academic performance among learners.

Authors: Mansi Mehta , Kalika Bandamwar  
Published: March 2023

Background: Non-compliance to manufactures recommended replacement frequency is expected to result in ocular complications. While many reports the percentage of people who are non- compliant, only some report pay attention to the care and maintenance instructions that eye care practitioners provide to their patients. The goal of this study is to draw attention to the instructions imparted by eye care practitioner to their user and explore the measure taken by them to reduce contact lens non-compliance.
Method: Eye care practitioner from Mumbai who were willing to provide consent and share their experience participated in this anonymous online survey which was designed with the help of focused group discussion with a panel of experts.
Results: Majority of eye care practitioner had 5 years or more clinical experience in the field of contact lens. About 81% contact lens users in their practice were between the age of 20-29 years. These eye care practitioners believed their contact lens user non-compliant to replacement schedule of contact lens, was 35% due to forgetting the actual day of replacement, 46% as they forget to reorder their lenses, 33% believe to do this to save money, 41% believe contact lens user have lack of time and 36% believe they don’t change their lenses as there is no discomfort in continuing. Of all 55% of eye care practitioner agree in giving written information, SMS or telephonic reminder and agreed that increase in follow up would improve compliance. However, 57% of eye care practitioner strongly agree that contact lens practice should be restricted to Eye care practitioner only to increase compliance in contact lens users.
Conclusion: Reminders to follow up and to buy contact lens as per their previous purchase can help in reducing majority of non-compliance to replacement schedule. In addition, eye care practitioner strongly agrees to restrict contact lens practice to Eye care practitioner only.
