Aim: Reconstruction of tongue defects has always been a challenging aspect of onco-surgery. Although a variety of locoregional and free flaps have been advocated, it still poses a challenge due to its complex function in deglutition and speech articulation. Hence, this study aims at reducing the dilemma of flap selection for better patient outcome. Materials and Methods: Among 16 tongue carcinoma cases, 6 cases were reconstructed using submental island flap (SIF) and 10 using radial forearm free flap (RFFF). These 2 flaps were compared in terms of parameters like intraoperative time, hospital stay, overall survival, pain, cosmesis, and recreation of anatomy, and functions like deglutition and articulation of speech. Patients were followed for oncologic safety and recurrence. Obtained data were statistically analysed using IBM® SPSS®. Result: SIF showed significantly higher activity score (P = 0.001) with reduced flap harvest time (P = 0.014) but showed difficulty in deglutition (P = 0.03) compared to RFFF. It was concluded that in cases of RFFF mobility and functional outcome was superior, but flap harvest time was considerably higher. Overall patient survival rate was better in cases of RFFF in long-term follow-up, but flap survival rate was significantly higher in SIF owing to better vascularity. Conclusion: In highly compromised cases and salvage cases where microvascular flaps are contraindicated, submental flap being a local flap with comparable overall survival rate, better cosmesis hence, serves as a reliable flap for reconstruction of glossectomy defects. © The Association of Oral and Maxillofacial Surgeons of India 2024.

(Wolters Kluwer Medknow Publications, 2024) Farhan Durrani; Aishwarya Pandey; Shweta Ahlawat; Ekta Kumari; S. U. Gokila Vani; Sakshi Agarwal; P. G. Naveen Kumar
Background: Dental implants in fresh extraction sockets of the maxillary esthetic area are technique-sensitive procedures where retaining a buccal root segment can enhance periodontium preservation and esthetics. This study aims to compare marginal bone levels and esthetic outcomes between conventional immediate implant placement and the socket-shield technique in fresh maxillary extraction sockets. Materials and Methods: Twenty-four patients with type 1 extraction sockets were included in this randomized trial and assigned to either conventional immediate implant placement or the socket-shield technique. Implant survival, crestal bone levels, and pink esthetic scores (PES) were evaluated at 8 months (temporary prosthesis), 12 months, and 36 months (final crowns). Results: All implant-supported restorations were successful within the study's observation period. The socket-shield technique showed significantly lower marginal bone loss (e.g. 1.40 ± 0.29 mm vs. 1.70 ± 0.36 mm at 36 months; P = 0.040) and superior PES (e.g., 10.50 ± 0.90 vs. 9.36 ± 0.98 at 36 months; P = 0.008) compared to the conventional technique. However, the technique's complexity underscores the need for expertise and careful execution to optimize tissue preservation in the maxillary esthetic zone. Conclusion: The socket-shield technique better preserves hard and soft tissues around implant-retained prostheses than conventional implant placement in maxillary esthetic regions. Further studies with larger sample sizes and longer follow-up are required to validate these findings. © 2025 Indian Society of Periodontology.
Comparative evaluation of pit & fissure sealant retention using cotton roll & rubber dam isolation techniques – a systematic review & meta-analysis
(Springer Nature, 2024) Neha Shukla; Zainab Akram; P. G. Naveen Kumar; Mahesh R. Khairnar; Sachin Kumar Jadhav; Savitha Priyadarsini
Background: Isolation with cotton rolls does not always provide as complete isolation as rubber dam, especially in procedures where absolute moisture control is critical. Therefore, this review aims to summarize and analyze previous studies evaluating the retention and marginal integrity of pit & fissure sealant using rubber dam and cotton roll isolation techniques during dental treatment in children. Material and methods: In accordance with PRISMA guidelines, search yielded 1361 articles, with seven RCTs and one non-RCT design meeting the inclusion criteria. Data were extracted on study design, sample size, sealant type, follow-up duration, retention rates, and caries incidence. Results: The comparison of retention rate between rubber dam and cotton roll at six months difference was non-significant (OR:1.15; p = 0.64) while there was significant difference at 12 month (OR:2.23; p < 0.001). The difference for the marginal integrity was statistically significant at six months (OR:2.00; p = 0.03) while non-significant difference observed (OR:1.74; p = 0.10) at 12 months. Conclusion: The sealant placed using a rubber dam as an isolation technique showed higher retention than the cotton roll after 12 months. In terms of marginal integrity, the performance of the rubber dam and cotton roll was equivalent at the end of 12 months. © The Author(s), under exclusive licence to British Dental Association 2024.
Dental Age Estimation using Demirjian's Methods: A Comparative study
(Red Flower Publication Pvt. Ltd, 2022) Ramkrishna Mishra; Vinay Kumar Srivastava; Surendra Kumar Pandey; P. G. Naveen Kumar
Introduction: Context: There are various methods have been developed for dental age estimation, of these; Demirjian's seven tooth method is most tested and accepted method worldwide. It is based on the tooth development rather than tooth eruption, because developmental process is strictly controlled by genes and less influenced by dietary insufficiency, endocrinal disturbances and environmental insults. Aims: The purpose of this study is to evaluate the applicability of two Demirjian's methods in a sample of the Varanasi region. Setting and Design: This is a cross sectional prospective study. Methods and Material: The evaluation of digital panoramic images of a total 432 children and adolescents (237 boys and 195 girls) of age rang 3-16 years from population of the Varanasi region. Seven left mandibular teeth excluding third molar were rated and scored to obtain dental age using Dem73 and Dem76 methods. Statistical analysis used: Paired t-test was applied to determine the significant difference between estimated dental age and chronological age and correlation was established using Pearson's correlation coefficient. Results: The Dem73 method overestimated the dental age in boys by 0.23 (±0.80) years and by 0.12 (±0.85) years in the overall sample. In the girls' sample, there was no discernible difference in mean age. In boys, girls, and the total sample, Dem76 method overestimated dental age by 0.85 (±1.14), 0.45 (±1.00), and 0.67 (±1.10) years, respectively. Pearson's correlation revealed high coefficient value between dental and chronological ages. Conclusions: Dem73 method is more applicable than Dem76 method for age estimation among children and adolescents in the Varanasi region. © 2022,Indian Journal of Forensic Medicine and Pathology.

(Jaypee Brothers Medical Publishers (P) Ltd, 2021) Ipshita Potlia; P. G. Naveen Kumar; Manumanthu V. Ramesh; Himanshu Chauhan; Arun R. Nair; Alok K. R. Singh
Aim and background:Dental plaque and calculus are common in school-aged children worldwide causing unsatisfactory oral health. This stage is a critical time to establish attitudes, beliefs, and shape an individual’s health-related behavior. Moreover, parental oral health knowledge and attitudes are known to influence their child’s oral health and hygiene. Materials and methods: A cross-sectional study with a two-stage intervention trial involving a sample of 6-year-olds from two schools in Davangere city was done. Children were randomly allocated into three intervention groups by lottery method. Data included plaque index (PI) modified for 6-year-old children at baseline, 30th day, and at 60th day. Children and their mothers were requested to fill a self-administered questionnaire. The statistical analysis used ANOVA followed by Tukey’s post hoc test and measures ANOVA. p ≤ 0.05 was considered statistically significant. Results: There was a significant reduction in the PI modified in 6-year-olds within and among the three groups at the end of 60 days (p = 0.001). Maximum reduction was seen in group II followed by group III and thereafter group I in both the age-groups. Conclusion: The study shows that at 60 days, the oral health infotainment module involving parental support was able to achieve appreciable improvement in the child’s oral health and hygiene and inculcate a better attitude toward oral self-care. © The Author(s). 2021.
Evaluation of Arthrocentesis with and Without Platelet-Rich Plasma in the Management of Internal Derangement of Temporomandibular Joint: A Randomized Controlled Trial
(Springer, 2021) Akhilesh Kumar Singh; Naresh Kumar Sharma; P. G. Naveen Kumar; Shreya Singh; Nitesh Mishra; Rathindra Nath Bera
Purpose: The purpose of this study was to compare the efficacy of intra-articular injection of platelet-rich plasma after arthrocentesis versus arthrocentesis alone as a treatment modality in patients with internal derangement of temporomandibular joint. Methods: Twenty-four patients suffering from internal derangement of temporomandibular joint were included in the study. The patients were randomly divided into two groups as follows—twelve patients underwent arthrocentesis followed by intra-articular injection of platelet-rich plasma (study group) and the other twelve were treated by arthrocentesis alone (control group). Pain intensity was recorded on visual analogue scale (VAS); maximum mouth opening and joint sound were measured before and after intervention. The patients were clinically evaluated at the intervals of 1 month, 3 and 6 months subsequently. Results: There was no statistically significant difference in all the parameters between the groups. Intra-group analysis showed statistically significant improvement in all the parameters. Conclusion: In both groups, improvement of pain, maximum mouth opening and TMJ sound were observed at all intervals, but there was no statistically significant improvement in arthrocentesis with PRP group when compared with arthrocentesis alone. © 2019, The Association of Oral and Maxillofacial Surgeons of India.
