Regenerative endodontic therapy (RET) of young permanent teeth with necrotic pulps and apical periodontitis in young people, deciduous tooth pulp may be utilized as a natural, biologic scaffold. Recent developments in stem cell biology and material sciences are beneficial for new treatment methods. Previously traumatized and necrotic young permanent tooth was treated with RET protocol. In the first visit, irrigation, and placement of triple antibiotic paste dressing were done. After that in the second visit, intracanal medication was removed and whole pulp tissue harvested from the deciduous tooth was transplanted in the young permanent tooth. Following placement of Biodentine^® coronal barrier, access cavity was restored with acid-etch resin composite. This case report would highlight favorable outcome of RET using deciduous pulp autotransplantation in young permanent tooth using cone-beam computed tomography for 6 months' follow-up.

Introduction: Ninety-five percent ethanol is the routinely used and standard cytological fixative. However, commercially available ethanol is expensive and not freely available in some institutions. There is always a search for an ideal alternative.

Aim and objective: In the present study, we evaluated 100% coconut water (CW) and 30% aqueous honey solution as cytological fixative at different time points and compared them with routinely used spray fixative of ethanol.

Materials and methods: Oral smears were prepared from 30 healthy volunteers, and a total of 270 smears were prepared. From each volunteer, 9 smears were prepared. One smear was fixed in ethanol, four smears were fixed in 100% CW and four in 30% aqueous honey solution. Of the four smears fixed in CW or honey, one smear was fixed for 15 min, one for 30 min, one for 45 min, and one for 1 h, respectively. The slides were dried and then the smears were stained with Papanicolaou staining. Slides were evaluated by two independent observers who were blinded to the procedures. The following parameters were evaluated - nuclear staining, cytoplasmic staining, cell morphology, clarity of staining, and uniformity of staining. Statistical analysis was done using post hoc pairwise comparison, and P < 0.05 was considered to be statistically significant.

Results: The results of the study showed that fixation with 30% aqueous solution of honey or 100% CW for more than 15 min yields useful and evaluable results.

Conclusion: These readily available materials can be used as alternatives of alcohol in oral cytology.

Background: Preventive dental procedures are cornerstones of caries management.

Introduction: This research aims to analyze the clinical effectiveness of pit and fissure sealants when applied to etched enamel pretreated with solvents compared to the conventional etch and seal technique.

Subjects and methods: Children and adolescents with clinically healthy occlusal surfaces or noncavitated occlusal carious lesions on permanent first and/or second molars in all four quadrants were randomly allocated into four groups. A total population of 87 participants (348 teeth) were selected for the research based on the inclusion criteria. Following the enrollment, teeth were etched and sequentially assigned for application of Group 1 = Conventional Etch Seal (control group), Group 2 = isopropyl alcohol (IPA), Group 3 = acetone, and Group 4 = ethanol before sealant application. All participants were evaluated for marginal integrity, discoloration, and clinical retention of pit and fissure sealant after 6-month intervals and 12-month intervals using Feigal's criteria.

Results: At 6-month and 12-month intervals, the collected data were compiled and statistically analyzed using the Chi-square test of significance for marginal integrity between groups all four groups. The Wilcoxon rank test was assigned to assess the difference between parameters measured at 6 months and 12 months. A highly significant difference was found between the groups (P < 0.05) for marginal integrity and anatomic form at 6 months and 12 months when intergroup comparison was done using the Kruskal-Wallis test.

Conclusion: Surfactants such as IPA and acetone can be adopted while choosing methods for the long-term clinical success of resin-based sealants for increasing wettability and penetration depth.

Background: Oral cancer is one of the ten most common cancers worldwide and the sixth most common type of all cancer in India. Among the oral malignancies, oral squamous cell carcinoma (OSCC) is the most common, accounting for more than 90% of oral cancer and hence a significant public health concern.

Aim: The aim of this study was to evaluate clinicopathological and demographic profiling of OSCC in a district and adjacent area of lower Assam.

Settings and design: This was a retrospective observational study.

Materials and methods: A total of 140 histologically confirmed OSCC patients diagnosed at the Regional Cancer Centre in the district between the period 2022 April and 2023 October constitute our study sample size in this study. The duration of the study was 1½ years.

Statistical analysis: The clinical and histopathological features were analyzed using descriptive statistics. Statistical Package for the Social Science (SPSS) version 23.0 was used.

Results: OSCC constitutes 23.97% of head-and-neck cancer. The incidence of OSCC was higher in males. The highest number of patients was in the age group of 50-59. The most common site of OSCC was the buccal mucosa followed by the tongue. Most of the cases were well differentiated, the number being 82 (58.57%). Most of the patients were in Stage III and Stage IV.

Conclusions: The present study highlights that in the lower Assam region, the majority of the OSCC patients are middle-aged male patients with advanced stages of OSCC. The findings from the present study can be used to compare the scenario of OSCC in other parts of Assam and North East India and also can be used for a follow-up study.

The inclusion of precision medicine in medical education represents a paradigm shift, as it is expected to transform the way in which health care will be delivered to patients in future. This shift is predominantly reported as precision medicine strongly advocates for the delivery of personalized care to patients after giving due consideration to the genetic makeup, biomarker level, etc., of the individual patient. Medical professionals are expected to discharge a wide range of roles since the introduction of precision medicine in the health-care industry. Training of medical students and health professionals in the domain of precision medicine is expected to significantly influence patient outcomes and enhance the efficiency of the health-care sector. In conclusion, precision medicine is expected to have a huge impact on medical professionals and the health sector, it is the need of the hour to strengthen its implementation process across medical colleges and health-care facilities.

In the field of clinical training, entrustable professional activities (EPAs) generally deal with those activities that health-care professionals will be encountering in their routine practice, and thus exposure to these activities prepares them for their future clinical practice. Workplace-based assessment tools have been used to assess the progress of medical students across these defined EPAs. The act of development of EPAs essentially requires the adoption of a systematic process to identify and define the core tasks and responsibilities that medical students must be able to perform independently in a specific specialty. The process of integration of EPAs into the medical school curriculum essentially requires systematic planning and implementation to ensure that students get an adequate number of opportunities to develop and demonstrate the desired competencies. In conclusion, EPAs provide an excellent framework for transforming medical education by preparing medical students to be ready for the complexities of health-care delivery.

Adenomatoid odontogenic tumors (AOT), first described by Steensland in 1905, are benign, slowly enlarging, nonaggressive, odontogenic epithelial neoplasms comprising 3%-7% of all odontogenic tumors. They tend to originate from the dental lamina remnants or the reduced enamel epithelium. Mutation at codon 12 of KRAS oncogene (Kirsten rat sarcoma viral oncogene homolog) plays a pivotal role in the pathogenesis. AOTs demonstrate three clinicopathological spectrums, namely follicular, extrafollicular, and peripheral. The extrafollicular AOTs are hypothesized to originate from a stimulus triggering the dental lamina remnants. While intraosseous follicular AOTs are fairly common (70.8%), the extrafollicular counterparts are infrequent (24%), and novel entities that may mimic other lesions due to the absence of tooth inside. Herein, we elucidate a series of five unique extrafollicular AOT cases with a relevant emphasis on its pathogenesis and clinico-radiological aspects. This report aims to add another significant record to the literature pertaining to the compilation of extrafollicular AOTs.

This article outlines the orthodontic treatment of a 21-year-old female patient with an open bite and temporomandibular joint disorders (TMDs) that developed after a severe car accident. The treatment plan utilized temporary anchorage devices (TADs) for upper molar intrusion to correct the open bite without resorting to orthognathic surgery. Over a period of 3 years, the treatment achieved a stable occlusion, normalized molar relationships, and improved esthetics. Despite the persistent of TMD symptoms, the patient experienced enhanced jaw movement and a reduction in abnormal chewing cycles. The combination of orthodontic treatment with TADs and splint therapy contributed to successfully restoring both esthetic and functional aspects. This case underscores the efficacy of TADs in addressing trauma-induced malocclusions, highlighting the potential for minimal intervention to achieve comprehensive treatment outcomes.

Dental students often prefer social media for its accessibility and low cost but must critically evaluate the content before applying it in practice. This study analyzed YouTube content on socket shielding. A new Google account was created to search for "Socket Shield Technique" and "Partial Extraction Therapy." Eligible videos were assessed for quality using the Global Quality (GQ) tool and the DISCERN tool. Statistical analysis was performed using the Statistical Package for the Social Sciences software. Results showed an average of 28.35 likes per video, no dislikes, and substandard content indicated by a DISCERN score of 25.25 ± 2.4 and a GQ score of 1.82 ± 0.38. The study concludes that video content on socket shielding is not reliable, emphasizing the importance of clinical observation and hands-on practice.
