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.
Comparative Evaluation of Implant Stability in Single Tooth Implant with Either Immediate or Delayed Functional Loading Protocol: A Prospective Clinical Study
(Jaypee Brothers Medical Publishers (P) Ltd, 2025) Kumari Deepika; Atul Bhatnagar; Harshika Gautam; Pg G.Naveen Kumar
Purpose: The present study was done to evaluate and compare implant stability for a single tooth implant with either an immediate or delayed functional loading protocol. Materials and methods: Twenty participants were assigned to each group: DL (delayed loaded) and IL (immediate loaded). Implant stability quotient (ISQ) was measured using resonance frequency analysis (RFA) at baseline and at scheduled follow-ups (DL: 3, 6, and 9 months; IL: 6 weeks, 3, and 6 months). Intergroup comparisons were performed using unpaired t-tests, intragroup changes with repeated measures ANOVA, and the correlation between ISQ and insertion torque (IT) was analyzed using Pearson’s coefficient. Results: All implants demonstrated adequate primary stability (ISQ ≥ 75) with high IT, and healing was uneventful. ISQ values were comparable between groups at baseline and 3 months (p?> 0.05), with a significant difference at 6 months (p < 0.05). Within-group ISQ changes over time were not significant; with DL showing a slight increase and IL a minor early dip followed by recovery. Both loading protocols maintained sufficient stability up to 6 months. A positive correlation between IT and ISQ at placement (DL: r = 0.211; IL: r = 0.321; p < 0.05) indicated that higher torque was associated with higher initial stability. Conclusion: Though the delayed loading (DL) protocol may still remain the treatment of choice, based on present findings, it may be concluded that an immediate functional loading protocol can be performed in implants with sufficient primary stability. © The Author(s).
Comparative evaluation of pit & fissure sealant retention using cotton roll & rubber dam isolation techniques – a systematic review & meta-analysis
(Springer Nature, 2025) Neha Shukla; Zainab Akram; Pg G.Naveen Kumar; Mahesh R. Khairnar; Jadhav Sachin Kumar; Savitha S. 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.
COMPARATIVE EVALUATION OF RETENTION AND CARIES PREVENTIVE EFFECT OF HYDROPHILIC AND HYDROPHOBIC PIT AND FISSURE SEALANTS: A SYSTEMATIC REVIEW AND META ANALYSIS
(Elsevier Inc., 2025) Jadhav Sachin Kumar; Zainab Akram; Pg G.Naveen Kumar; Mahesh R. Khairnar; Neha Shukla
Background: Dental sealants are critical in preventing caries by protecting pits and fissures from food and microorganism accumulation. Sealants are categorized as hydrophobic and hydrophilic. Hydrophobic sealants exhibit higher retention but less effective in moist environments, hydrophilic sealants perform better under such conditions. Evaluating retention and caries prevention efficacy of these sealants is essential for optimizing dental care practices. This review evaluates retention and caries preventive efficacy of both sealants. Materials and Methods: Data on study design, sample size, sealant type, follow-up duration, retention rates, and secondary caries incidence were extracted. The risk of bias assessed using RevMan 5.4, and meta-analyses were conducted with both random-effects model and fixed-effects model based on heterogeneity and nature of included studies. Results: Adhering to PRISMA guidelines, 15 Randomized Controlled Trials (RCTs) and 3 Non-Randomized Controlled Trials (NRCTs) met with inclusion criteria. Hydrophilic sealants showed significantly higher retention rates at 3 months (OR: 3.00, 95 % CI: 1.46-6.16) and 12 months (OR: 2.00, 95 % CI: 1.35-2.96). However, no significant differences observed at 6, 9, and 18 months. Caries prevention efficacy was similar for both sealant types across all follow-up periods, with low heterogeneity indicating consistent results. Discussion: Hydrophilic sealants initially provide better retention due to moisture-resistant properties but do not sustain this advantage in long run. Both sealant types are equally effective in preventing caries. These findings align with prior studies, emphasizing importance of moisture control in sealant application. Conclusion: Hydrophilic sealants exhibit superior short-term retention and similar caries prevention efficacy compared to hydrophobic sealants. © 2024 Elsevier Inc.
