Published: July 2022

Introduction:
Orthodontic treatment may bring about changes in the temporomandibular joint (TMJ) disc. Hence, we aim to assess the impact of the orthodontic tooth movement on the articular disc repositioning of TMJ.

Materials and Methods:
We conducted an observational prospective study among 50 class IIdiv-I subjects. The magnetic resonance images were used to evaluate TMJ during the orthodontic treatments. The phases were T1-start of treatment, T2-thru phase I, T3-at the end of phase I, and T4-at the end of phase II. The qualitative values were compared for the disc changes.

Results:
No significant changes in the disc position or the regression were seen with open or closed mouth between T1-T3, T3-T4, and T1-T4. Significant variation for the position of the disc was seen in the opened mouth between T3-T4. Significant variation for the form of the disc was seen when closed at T1-T2 and T2-T3.

Conclusions:
Disc of the TMJ maintained the form and position during the treatments.

Published: July 2022

Background:
Gypsy “Narikuravars” constituted separate sociocultural groups having distinct cultures, customs, traditions, and lifestyles. Oral health-seeking behavior of this group remains to be an ignored part. This study aims to assess the oral hygiene practices and knowledge on periodontal diseases and therapy among Gypsy Narikuravars in Puducherry.

Materials and Methods:
The total study population consisted of 100 subjects, and a performed validated pro forma about oral hygiene practices and knowledge on periodontal diseases was used.

Results:
There is no significant association between sociodemographic factors and knowledge on periodontal disease and therapy. Majority (90%) of the participants have poor knowledge of periodontal disease and therapy. 56% of the participants used their fingers to clean the teeth, and very few subjects (13%) used toothbrush to clean their teeth, and most of the participants (92%) brushes once daily using manual method.

Conclusion:
The practice of poor oral hygiene and lack of knowledge on periodontal disease and therapy was observed. Hence, the implementation of oral health programs and provision of comprehensive health services for these Gypsy population should be a high priority.

Published: July 2022

Objective:
The objective of the study was to compare the perception of patients and dentists regarding the esthetics achieved with conventional and characterized complete dentures.

Materials and Methods:
Twenty completely edentulous participants were selected and given both conventional and characterized complete dentures. Participants including patients wearing the dentures and dentists subsequently evaluated both types of dentures by giving scores using 0–10 cm Visual Analog Scale on denture esthetics. The esthetic scores were statistically analyzed using paired t-test (P = 0.05 as significant).

Results:
Patients' satisfaction with conventional and characterized complete dentures were statistically similar except for the fact that patients were more satisfied with ideal arrangement of teeth in conventional denture (standard deviation [SD]-7.0 ± 2,0) compared to the characterized (SD-4.8 ± 2.7) arrangement of the teeth (P = 0.038).

Conclusions:
Aesthetic satisfaction with complete dentures was influenced by the patients' socioeconomic status. Patients could not see any significant difference between conventional and characterized complete denture.

Authors: Pawar Ranjit Omprakash , Narote Priyanka Sadashivrao , Gawai Kailas Tukaram , Amte Manjiri Prakash , Singh Sandeep , Sonkesriya Subhash 
Published: July 2022

Background:
Zirconia and other dental pottery, heat-restored polymethyl methacrylate, titanium and other metal amalgams, or a mix of these materials are utilized to fix inserts. It is important to choose a material that is resistant to bacterial colonization for implant-supported prostheses, but durability and aesthetics are important factors as well.

Aim:
Biofilm generation on materials used in implant-supported dental prosthesis manufacturing was an objective of this investigation.

Methods and Materials:
In this study, 90 discs were prepared. These discs were divided into three groups: group PMMA, group Y-TZP, and group CP-Ti. Each group consisted of 30 discs. As helpful materials, 30 discs (D = 15 mm, H = 3 mm) each were created from either monetarily unadulterated titanium (CP-Ti), yttria tetragonal zirconia polycrystal (YTZP), or hotness-restored polymethyl methacrylate (PMMA). The examples were cleaned as per acknowledged practices. The non-contact profilometer (NPFLEX, Bruker, UK) was utilized to survey the surface rougness of each disc, and the outcomes were accounted for as Ra (m). An assortment of gram-negative microbes, including Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Porphyromonas gingivalis, Prevotella intermedia, and Tannerella albicans, were refined close by cleaned discs produced using heat-relieved PMMA, Y-TZP, or CP-Ti to see which type of biofilm is shaped best. CFU/mL was the unit of estimation (state framing units per milliliter).

Results:
Y-TZP discs have a substantially higher Ra (349 41 m) than PMMA and CP-Ti discs. Some bacteria that have been associated with peri-mucositis and peri-implantitis may be less prevalent on Y-TZP or CP-Ti discs. Biofilm development must be considered while making implant-supported prostheses using Y-TZP and CP-Ti.

Conclusion:
Y-TZP and CP-Ti are preferred materials for implant-supported prosthesis production because of biofilm development.

Published: July 2022

Background:
Sinonasal squamous cell carcinomas (SCCs) present a great challenge in their diagnosis and management owing to their rapid growth, regional recurrence, local recurrence, and aggressive spread locally.

Aims:
The present clinical trial was conducted to evaluate anatomic subsites' impact on the outcomes concerning SCCs affecting ethmoid sinuses and nasal cavity.

Materials and Methods:
Medical records for tumor staging, tumor classification, grading (histologic) clinical features, symptoms, anatomic subsite, p16 results, treatment provided, and the Tumor-related outcomes were obtained for 28 subjects. Following staging and grading, p16 assays were evaluated along with disease-specific survival and disease-free survival. The collected data were subjected to the statistical evaluation and the results were formulated by keeping the level of significance at P < 0.05.

Results:
Origin was seen from nasal septum, nasal floor, lateral wall, ethmoid sinus, and edge of naris to mucocutaneous junction in 21.4% (n = 6), 7.14% (n = 2), 35.71% (n = 10), 7.14% (n = 2), and 28.57% (n = 8) subjects, respectively. For tumor staging, Stages I, II, III, and IV tumors were seen in, respectively, 39.28% (n = 11), 21.42% (n = 6), 10.71% (n = 3), and 28.57% (n = 8) study subjects. Node status was N0, N1, N2, and N3 in 78.57% (n = 22), 3.57% (n = 1), 7.14% (n = 2), and 10.71% (n = 3) subjects. Carcinoma arising from nasal septum had statistically significant worse disease-specific survival compared to carcinomas arising from other sites (P < 0.001).

Conclusion:
The present study concludes that anatomic subsites largely govern the outcomes and tumor behavior. Also, squamous cell carcinoma affecting the nasal septum is an aggressive tumor with more compromised outcomes and more lymph node involvement.

Authors: Alamoudi Ruaa A. , Basahel Mahfouz M. , Almehayawi Nouf F. , Alazaiqi Mohammed A. , Alghamdi Nuha S. 
Published: July 2022

Introduction:
Expired gutta-percha (GP) can lose its mechanical properties. This study aimed to compare the tensile strength values between expired and nonexpired GP-cones and to assess the outcome of different heat temperatures on this strength.

Materials and Methods:
Two-hundred-forty ProTaper points were obtained from nonexpired and 2 years expired pack with two different subgroups (sealed or exposed to air and light). All groups were subjected to the following treatments: control, 90°C water bath and cool either at room temperature or 0°C and 70°C water bath and cool either at room temperature or at 0°C. The strength under the tensile load was calculated using the universal testing machine.

Results:
The collected data were evaluated by one-way analysis of variance. Tensile strength for all control groups did not show any difference. Significant increase in the tensile strength in groups heated for 1 min in a water bath at 70°C, the tensile strengths were 8.19 ± 2.72 Mpa and 5.94 ± 1.14 Mpa cooled at 25°C and 0°C, respectively, P ≤ 0.001. Two years expiration did not lower the tensile strength of the GP and exposure to air and light did not show any change. Appropriate storage of GP is a key factor to extend its lifespan.

Conclusion:
A clinician may consider using expired GP as long as there are no noticeable changes in their structure and properties. A simple chairside technique using hot water may be helpful in restoring the mechanical properties of expired GP.
Exploration of Serum Prostatic Specific Antigen Level in Enlarged Prostate with its Histopathological Correlation
Authors: Sharma Malvashree , Jamaiyar Anshu 
Published: July 2022

Introduction:
Prostate lesions are of common occurrence in men, particularly in old age. Digital Rectal Examination (DRE) has remained a primary screening diagnostic aid for these lesions coupled with ultrasound and biopsies. The discovery of Prostate-Specific Antigen (PSA) has led to novel pathways in the detection of these lesions, particularly for malignant types. Hence this study was undertaken to correlate histopathological findings with PSA levels in a health care facility in Ranchi.

Material and Methods:
The study was conducted in Rajendra Institute of Medical Sciences, Ranchi. Serum PSA values and histopathological evaluation of prostatic biopsies were conducted and correlated. Raised serum PSA levels were divided into three groups based on set values.

Results:
A definite predilection for older ages was noted, with the 5th and 6th decades having the highest numbers of prostatic lesions. The sensitivity of PSA in the detection of carcinoma prostate cases was calculated to be 81.8%. The sensitivity of DRE was found to be 45.45% in the detection of cases of carcinoma of the prostate.

Conclusion:
The current study demonstrated serum PSA levels to be a reliable front-line technique in assessing an individual's risk for prostatic lesions.

Authors: Virkar Yogiraj B. , Chawla Jitendra , Changmai Arindom , Kumar Krishna , Abhishek Kumar , Jawaid Moazzam 
Published: July 2022

Background:
Surgical excision of the problematic mandibular third molars causes substantial tissue damage and an inflammatory response. Discomfort and edema are common postoperative signs and symptoms caused by the latter. To find out whether dexamethasone may help with the edema and pain that come along with the surgical removal of impacted mandibular third molars, researchers have performed clinical studies.

Methods:
Twenty individuals with bilaterally affected mandibular third molars who were scheduled for extraction participated in a prospective trial. At two separate sessions, teeth were raised and cut after buccal ostectomy. Since the surgical operation on the left foot, both patients were administered a mixture of 4 mg dexamethasone submucosal injection and antibiotics for 3 days. On the 1st, 3rd, and 7th postoperative days, edema and pain were assessed.

Results:
At the 1st, 3rd, and 7th postoperative days, there was a clinically meaningful decrease in the level of edema and discomfort in both arms.

Conclusions:
The current report offers empirical proof that administering a 4 mg dexamethasone submucosal injection during surgery greatly reduced post-surgical edema and discomfort.
