RESUMEN
Introduction Non-metric dental traits (NMDTs) are a fundamental data source in forensic dentistry. Nevertheless, the insufficiency of data regarding the occurrence of these traits has instigated the present research endeavor aimed at ascertaining the prevalence, sexual dimorphism, and extent of inter-trait correlations within the Maharashtrian population of India. The secondary objective was to determine the correlations between NMDTs, dentoskeletal malocclusion, and ABO blood groups. Materials and methods This prospective, observational study included 528 individuals aged 18-30 years with dentoskeletal Class I, II, and III malocclusions. NMDTs such as the presence of Cusp of Carabelli (CoC) on the upper first molars, hypocone on the upper second molars, and tri- or bicuspid lower second premolars were observed on the dental casts of all individuals. The dental relationship was assessed clinically according to Angle's system for the classification of malocclusion. The skeletal relationship was assessed using lateral cephalograms of the individuals. ABO blood groups were obtained from their medical records. The Chi-square test of independence was used to assess the associations between various variables. The correlation between each measurement was determined using Spearman's correlation test. Multivariate analysis enabled the identification of parameters that exhibited independent associations with NMDTs. A multinomial logistic regression model was constructed using NMDTs as the outcome variable. Results The mean age of males was 20.82 ± 1.71 years and 21.15 ± 1.76 years was in females. NMDTs were predominantly seen in females (n=394, 75%), with Class II dentoskeletal malocclusion (n=265, 50%) and B blood group ((n=199, 38%). All traits showed bilateral predominance. A statistically significant association was found between CoC, dentoskeletal malocclusion, hypocone, and tricuspid lower second premolars (p <0.05). All NMDTs showed a negative correlation with sex, a positive correlation between age and the presence of hypocones and CoC, a negative correlation between age and tricuspid lower second premolars, a strong positive correlation with dentoskeletal malocclusion, and a weak positive correlation with ABO blood groups. Multinomial logistic regression model analysis revealed that none of the independent variables were statistically significant predictors of the presence of CoC and tricuspid lower second premolars, while dentoskeletal malocclusion and sex were significant predictors of the presence of the hypocone trait. Conclusion NMDTs showed a female predilection with bilateral predominance. A significant association was observed between these traits and dentoskeletal malocclusions. The most commonly observed NMDT was the presence of a hypocone on the upper second molars, followed by the tricuspid lower second premolars and the CoC.
RESUMEN
INTRODUCTION: Oral cancer is recognized as the sixth most common type of cancer globally. Instances have been recorded demonstrating an increase in its incidence, particularly in the territories of southern Asia, with a significant emphasis on India. Thus, the objectives of this investigation were to assess the efficacy of a holistic approach on the life expectancies of patients diagnosed with oral cancer, and to assess the prognostic indicators in such patients. MATERIAL AND METHODS: A retrospective study was conducted on medical records of 60 clinically and histopathologically confirmed cases of oral squamous cell carcinoma (OSCC) who received complete surgical intervention or radiation therapy or a combination of both modalities depending on stage of OSCC from January 2015 to December 2016. After completion of their treatment, 30 patients underwent Cancer Care program of Annabhai Chudamani Patil Memorial Medical College which consisted of yoga sessions, meditation, psychological counselling, nutritional counselling, emotional and social support (embracing a holistic approach, group 1) and 30 patients did not enroll in the Cancer Care initiative (not opting for holistic approach, group 2). The program was conducted for 21 days every six months for two years. Data pertaining to demographic characteristics, stage of OSCC, modalities of treatment administered, histopathological characteristics of the neoplasm, as well as the clinical outcome (Survival/Deceased) post a five-year duration subsequent to the primary diagnosis were extracted from the medical records to assess the role of holistic approach and various factors on the overall survival (OS) of the patients in both the groups. The data collected was subsequently subjected to a thorough statistical analysis. RESULTS: The mean age of the patients was 44.33±8.66 years (95% CI: 39.53-49.13) in group 1, and 51.20±9.99 years (95% CI: 39.53-49.13) in group 2. The mean survival time for group 1 was 81.60±5.02 months (95% CI: 78.817-84.383), and 66.00±20.29 months (95% CI: 54.761-77.239) in group 2 with statistically significant difference between the groups (p=0.007). Group 2 showed a 1.31 relative risk of mortality to group 1. The probability of death in group 2 was 1.39 times more than in group 1. Cox regression analysis revealed group 2 was significantly associated with the risk of OSCC in this analysis. Other variables were not significantly associated with the risk of the OSCC in this analysis. CONCLUSION: The current research indicated that employing a holistic strategy proves to be a successful approach in increasing the OS of patients with OSCC.
