Korra Swetha Rani, Paremala Konda, ND V. N. Shyam, G Kiran Kumar, Vaishali Narayen, Y Reshma
Background: Exfoliative cytology is the technique of microscopic examination of shed or desquamated cells from the epithelial surface of mucous membrane. Papanicolaou stain (PAP) is the common stain used for these cytological smears. Conventional PAP (cPAP) stain has undergone many modifications, of these ultrafast PAP (UFPAP) is a popular stain used as it shortens the staining time and quality. UFPAP was discovered as a fusion of Romanowsky and PAP. Aim and Objectives: To evaluate and estimate the quality of UFPAP and c PAP stains in oral cytology smears of normal mucosa (NM), oral squamous cell carcinoma (OSCC), and oral potentially malignant disorders (OPMDs). Materials and Methods: 50 samples/smears were collected from outpatients from the Government Dental College and Hospital, Hyderabad. Samples include 10 cases of NM, 20 cases each of OPMDs (leukoplakia) and OSCC. Two cytological smears of representative areas were obtained and each smear is stained by the cPAP and UFPAP stains, respectively. Results and Observation: The quality index is obtained for the comparison of UFPAP and cPAP stains by using four parameters like - nuclear details, over all staining, background staining, and cell morphology. QI for all parameters of UFPAP staining was good compared to cPAP and percentage of UFPAP for NM, OPMDs and OSCC was 92.7%, 88.1%, 66.3% respectively. Conclusion: The study concludes that UFPAP staining is used for diagnosis in a regular oral cytology smears to offer immediate diagnosis of OPMDs and OSCCs.

Shraddha Rajendra Shimpi, Swapna Arunkumar Mahale, Dipali Dhanraj Chaudhari, Ankita A Katkurwar, Jui Vilas Bhandare
Introduction: As a new emerging nanotechnology approach, copper nanoparticles (CuNPs) coated on traditional silk suture were used. Its antimicrobial and anti-inflammatory properties, led to its increasing medical applications. Commercially available as wound dressings, surgical instruments and bone prostheses. Objectives: To compare physical parameters of nano-copper and silk suture. Methodology: Copper nanoparticles and deionized water were adopted for the preparation of the copper solution. The copper solution was obtained by dissolving 0.5 wt/v % of copper nanoparticles in a mixture of 5 v/v % of deionized water. The silk suture were dipped in the copper solution for 24 hr and then exposed to UV lamp in order to induce the synthesis of copper clusters on the surface of the suture. Inverted electron microscopy was performed in order to analyse the braided structure of the multifilament silk sutures and to verify the presence of copper on the surface. A quantitative spectrophotometry analysis was performed to quantify the percentage of copper deposited. Tensile strength was measured by Universal Testing Machine. Results: Nano-copper suture showed enhanced physical parameters as compared to silk suture. Conclusion: Copper nanoparticles due to their beneficial effects as antibacterial and wound healing accelerator in the periodontal surgeries could reduce inflammation and promote healing process.

Kopal Sharma, Kanu Neemawat, Amit Sharma
Background: This study aims to study the predictors and the pattern of adverse drug reactions to Covishield vaccine which is being used in the mass vaccination program of the Government of India. Methods: This cross-sectional questionnaire-based study was conducted among the dentists working as faculty in four different tertiary care centers in Jaipur city. A prevalidated questionnaire was circulated through E-mail/social media groups to all the participants. Results: A total of 574 participants fulfilled the questionnaire platform; however, six had been excluded from the study due to incompletely filled questionnaires. The remaining 568 were enrolled for the final analysis. About 296 (52.11%) were male and 272 (47.89%) were female. About 52.8% were in the age group of 31–49 years. About 87.32% of the enrolled participants had received both doses of Covishield. Most common postvaccination symptoms were fever (n = 145), local pain at injection site (n = 123), tenderness at injection site (n = 117), and fatigue (n = 91). Female gender, presence of comorbid diseases, and past coronavirus disease-19 infection were statistically significant risk factors for having adverse reactions post vaccination, P = 0.02, 0.043, and 0.0002, respectively. Conclusions: The data suggest that Covishield is well tolerated in the Indian population. Fever, local pain, tenderness at injection site, and fatigue are few commonly reported side effects. All the side effects were mild to moderate in terms of severity.

Role of scan body material and shape on the accuracy of complete arch implant digitalization p. 114
Raadhikka Karthhik, Bharath Raj, BV Karthikeyan
Purpose: The aim of the study was to evaluate how the intraoral scan body (SB) material and shape affects the scanning accuracy and scan time in completely edentulous situations since it is not well understood. Methodology: Two SB systems were evaluated: SB-1 group (Polyetheretherketone (PEEK)/Flag shaped, Biohorizon, USA), and SB-2 group (Titanium/cylindrical shape, Bioline, GmbH). On completely edentulous mandibular model with 4 dental implants (TMR 4.6, Biohorizon, USA) with scan bodies were positioned in the first molar and canine. The model was scanned using a calibrated laboratory scanner (D2000; 3Shape) to generate a master reference model (MRM). Ten consecutive digital impressions Standard Tessellation Language file were made of the model using an intraoral scanner (Trios, 3Shape A/S) for both the test groups. The test scans were superimposed over the MRM using a best-fit algorithm, and then, the distance deviation and angular deviation of the scan bodies were calculated. Scan time was also recorded. Mann–Whitney U-test was used to statistical analysis. P > 0.05 considered statistically significant. Results: Statistically significant differences were found between the SB material and shape on the linear measurement, angular deviation, and scan time (P < 0.05). The SB-1 group achieved higher accuracy overall and also exhibited noticeably lower scan time. Conclusion: The quality of digital intraoral impressions seems to be influenced by both the geometry and material of the SB. For clinical practice, the PEEK material seems clinically beneficial for decision-making.

Gaurav Singh, Shailendra S Chauhan, Aditya Sinha, Satendra Sharma
Aim: A study was carried out to determine how effective diode lasers and Metrohex Plus Gel are at managing chronic periodontitis when compared to standard periodontal therapy. Materials and Methods: A total of 90 sites having periodontal probing depth (PPD*) ≥5 mm were included with patients aged around 35–60 years. Each group contains 30 sites as follows: Group I – laser-assisted new attachment procedure*, Group II – Metrohex Plus Gel, Group III – scaling root planing (SRP)* alone. Results: Based on the average gingival index* value at baseline, 1 and 3 months, the values were 1.9 ± 0.67, 0.99 ± 0.26, and 0.89 ± 0.19, respectively. The mean plaque index* score decreased to 1.12 ± 0.31 at 1 month and 0.80 ± 0.31 at 3 months from 2.30 ± 0.58 at baseline. A PPD* reduction of 0.85 ± 0.03 mm was observed at 3 months for sites treated with laser, which was significantly higher than the reductions for sites treated with Metrohex plus (metronidazole 10 mg + chlorhexidine gluconate 0.25% w/w and hyaluronic acid) and SRP* alone. PPD* reductions were not significantly different between Groups I and II. Group II showed a 0.35 ± 0.11 mm improvement in clinical attachment levels compared to Group III. Conclusion: As opposed to simple SRP, diode laser therapy and Metrohex Plus Gel improve all clinical parameters in patients with periodontitis.

Estimation of the inflammatory burden and its impact after treatment in periodontally affected pre- and postmenopausal women p. 131
Jammula Surya Prasanna, Sumadhura Chinta
Context: Menopause, when menstruation ceases, is seen with an overall increase in body response to inflammation. Gingiva is no such exception. Gingival inflammation which leads to periodontitis is a condition, which is severe inflammatory in nature, affecting the tissues surrounding the teeth. If not treated in time apparently tooth loss might take place. Pre- and postmenopausal conditions, more or less are critical for inflammatory changes. Aims: In this study, among both conditions which one was oppressive and which reciprocated more to scaling was examined. Settings and Design: This study was a cross-sectional interventional study. Materials and Methods: Sixty female subjects aged between 40 and 50 years with periodontitis were recruited. These were meticulously examined by a gynecologist and equated into two groups of 30 patients each, Group I – premenopausal and Group II – postmenopausal women. Plaque index, periodontal index (PDI), and sulcular bleeding index were compared at baseline and 3 months after scaling. Statistical Analysis Used: IBM Statistical Package for the Social Sciences (SPSS) version 21 software was used. An independent sample t-test was applied for percentage decrement and intergroup comparison and paired t-test for intergroup comparisons. Results: Reduction was significant in all the above parameters in both the groups noted on intragroup comparison from baseline to 3 months (P < 0.001). However, the intergroup showed no significance except PDI at baseline. Conclusions: There was a remarkable effect of scaling on inflammatory conditions such as menopause and periodontitis. In the premenopausal stage only, if women undergo periodontal therapy, it can prevent future aggressive inflammatory changes in the postmenopausal stage.

Management of Type III palatogingival groove in permanent maxillary lateral incisor with intentional replantation p. 136
Aaliya Rehman, Huma Iftekhar, Rajendra Kumar Tewari, Surendra Kumar Mishra
A palatogingival groove (PGG) is a developmental deformity that may cause a severe periodontal breakdown or combined endodontic and periodontal defect. In the present case, a 24-year-old patient reported a complaint of pain in the upper left front tooth region for 3 months. Clinical and radiological examination revealed a PGG in the permanent maxillary left lateral incisor. Cone-beam computed tomography showed multiple shallow grooves on the root surface and a deep palatal groove extending to the apex. Interdisciplinary management comprising endodontic therapy and intentional replantation was formulated. After endodontic procedure, tooth #22 was gently extracted. The shallow grooves were removed by odontoplasty. A Class II cavity was made in the deep palatal groove and was connected with the root-end preparation. The cavity was sealed with biodentin up to the cementoenamel junction and the coronal portion was sealed with light-cured glass-ionomer cement. The tooth was replanted in socket and splinted for 7 days. Follow-up visits revealed the functional status of tooth and complete bony healing. Tooth discoloration was successfully managed with intracoronal bleaching with sodium perborate. A 12-month radiographic follow-up revealed no evidence of root resorption or ankylosis.

Justin Mathew, S Akhil, Jubin Thomas, Fousiya Ali
Unicystic ameloblastoma (UA) is a rare, slow-growing, persistent, locally invasive, and cystic variant of ameloblastoma. This article presents two different variants of UA. The first case was a rare presentation of UA in an 11-year-old patient involving the impacted second molar, which is otherwise usually associated with an impacted mandibular third molar. It was diagnosed with UA-luminal type and treated by a piezoelectric ultrasonic device with minimal trauma to soft tissue. The second one was associated with impacted mandibular third molar extending the entire ramus of mandible till the coronoid which was diagnosed with UA-mural type and treated by cystic enucleation with platelet-rich fibrin graft. Recurrence was not observed during a 6-month follow-up. The aim of this case presentation was to give an insight into the destructive nature of UA and its diagnosis and management to maxillofacial surgeons as well as dental practitioners.

Application of artificial intelligence in the diagnosis and survival prediction of patients with oral cancer: A systematic review p. 154
S Canty Sandra, Anusha Raghavan, PD Madan Kumar,
Oral cancer constitutes around 2.1% and it is the sixth-most common malignancy worldwide and the third-most common type of malignancy in India. The purpose of this systematic review is to find the prediction of survival rate among oral cancer patients using artificial intelligence (AI) and its forms like machine learning. Suitable articles were identified by searching PubMed, Trip database, Cochrane, and Google Scholar host databases. The search was done with the help of PIO analysis where the population stands for oral cancer patients, the intervention given here were AI and its subsets and the outcome were diagnosis and survival prediction of oral cancer. The screening of the titles and abstracts was done, and only those articles that fulfilled the eligibility criteria were selected. The search resulted in 451 articles, of which only six articles that fulfilled the criteria were included. The studies showed that AI models were able to predict the 5-year survival rate among oral cancer patients. The accuracy of the decision tree classifier, logistic regression, and boosted decision tree models were 76%, 60%, and 88.7%, respectively. Modern age diagnosed people tend to have a longer survival rate than those diagnosed in the past. The limitation was that these studies were created using retrospective cohorts, but for validation, they must be compared with prospective cohorts. These studies are important for identification and survival prediction, which will contribute to future advancements, change in the treatment plan, and reduce health-care problems.
