RESUMEN
BACKGROUND: Among oral diseases, oral cancer is the primary cause of death and poses a serious health risk. Primary tumor (T) - regional lymph node (N) - distant metastasis (M) comprising (TNM) staging is crucial for planning treatment strategies for patients with oral squamous cell carcinoma (OSCC). AIM: This study evaluated the predictive accuracy of clinical TNM staging of OSCC to histopathological staging (pTNM) in an institutional setting. MATERIALS AND METHODS: Fifty-four consecutive histologically confirmed, surgically treated OSCC cases were evaluated for TNM staging. The study compared the clinical staging at the time of surgery with the pathological staging obtained from excisional biopsy reports. Microsoft Excel (Microsoft® Corp., Redmond, WA, USA) was used for the data compilation and descriptive analysis. The chi-square test, analysis of variance (ANOVA), and Tukey's Honest Significant Difference (HSD) posthoc test were used to compare the data for statistical significance with p value <0.05 using Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 23.0, Armonk, NY). RESULTS: The alveolar mucosa (n=22, 40.74%) was the most frequently occurring site, followed by the tongue (n=17, 31.48%). Out of the 54 included cases, based on clinical tumor size, there were T1 (n=6), T2 (n=13), T3 (n=13), T4a (n=16) and T4b (n=6). T2 tumors were usually upstaged (n=7) while T4a (n=8) tumors were most often downstaged. T4a (n=8) had the best concordance between clinical and histopathological staging, followed by T2, T3, and T1. In nodal status, N1 showed the most variation. The chi-squared test showed statistical significance for tumor size comparison (p <0.001) and nodal status comparison (p=0.002). ANOVA test did not show any statistical significance. Tukey's HSD posthoc test showed statistical significance (p=0.034) for N0 and N1 status. The highest concordance was shown by N0 and N1 followed by N2b. CONCLUSION: Preoperative radiological and clinical assessments are essential for deciding on a patient's course of treatment. However, not all patients may require radiographs to determine tumor size or nodal status assessment. Accurate diagnosis is vital for the treatment planning of OSCC.
RESUMEN
Background India has a high prevalence of oral potentially malignant disorders and malignant transformation. Cases of oral leukoplakia are not commonly encountered, and only a small cohort of patients undergo biopsies for the same. This study aims to assess the various etiological factors causing leukoplakia, the clinical features, histopathological findings, and treatment received by the patients who were histopathologically diagnosed with oral leukoplakia. Methodology Oral leukoplakia cases were included in this study from total biopsy samples received in the oral pathology department. Details were collected from the Dental Information Archival Software of our institution. The period analyzed was from January 1, 2021, to December 31, 2023. Relevant clinical and histopathological details were retrieved and tabulated. Statistical analysis (chi-square test) was used to assess the association between the clinicopathological parameters using SPSS software version 21.0 (IBM Corp., Armonk, NY, USA) with a significance level set at a p-value <0.05. Results A total of 76 oral leukoplakia cases were retrieved from 2,600 biopsy samples. The prevalence of oral leukoplakia was 3.1% to 3.4% for the three years. Leukoplakia was commonly observed in those aged 51 to 60 years (33%). Overall, 21% of the patients with leukoplakia showed severe epithelial dysplasia, 22% showed mild epithelial dysplasia, and 39% showed moderate epithelial dysplasia. Moreover, 30% of the patients presented with leukoplakia and oral submucous fibrosis and showed varying degrees of epithelial dysplasia. Finally, 45% of the patients were managed conservatively using pharmacotherapy. Conclusions Severe epithelial dysplasia was commonly associated with oral leukoplakia. Oral submucous fibrosis was also found to be associated with leukoplakia and showed epithelial dysplasia. None of our proliferative verrucous leukoplakia cases showed any association with oral submucous fibrosis. Surgical management was the preferred treatment.
RESUMEN
Introduction The mandible constitutes one of the skull's largest and strongest bones. Growth spurts can influence it, and it has a variety of dimorphic traits that can be used to identify sex. In addition to observing, comparing, and evaluating the potential for mandibular ramus flexure and bigonial breadth to discriminate between sexes using digital orthopantomograms (OPG), a retrospective study was conducted to examine the validity of this method for sex estimation in the Indian population. Aim and objective This study aims to quantify sexual dimorphism by analyzing two mandibular parameters, the ramus flexure and the bigonial width, using orthopantomography (OPG). The objective is to determine the accuracy of sex determination using the ramus flexure and bigonial width. Materials and methods A total of 500 OPG images (250 males and 250 females) were analyzed using the Planmeca software (Helsinki, Finland). The ramus flexure was measured as the angle formed between the tangent to the inferior border of the mandible and the tangent to the posterior border of the ramus. The bigonial width was measured as the distance between the left and right gonion points. A statistical analysis was performed to assess sexual dimorphism and determine the accuracy of sex determination using these parameters. The study employed descriptive statistics, such as means and standard deviations, and an independent t-test to determine the significance of the characteristics in relation to males and females. Results The mean bigonial width for females was 193.3068 mm (SD = 13.51669 mm) and for males was 217.6308 mm (SD = 10.87453 mm), with a statistically significant difference (p = 0.000). The 95% confidence interval for the difference in the bigonial width between males and females was between -49.97173 mm and -43.93787 mm. For the ramus flexure, the mean was 0.0000 for both males and females (SD = 0.00000), with a significant difference between males and females (p = 0.003). The 95% confidence interval for the difference in the ramus flexure between males and females was between -0.59543 and -0.12457. Conclusion The results indicated significant sexual dimorphism in both the ramus flexure and bigonial width. This study demonstrated that the ramus flexure and bigonial width, measured using orthopantomography (OPG), exhibited significant sexual dimorphism. The analysis of these mandibular parameters provided valuable information for sex determination in forensic and anthropological contexts.
RESUMEN
Background Dentigerous cysts (DC) form due to fluid accumulation between the crown of the tooth and the reduced enamel epithelium. Due to the diverse clinical characteristics, such as ambiguity concerning their biological origins and the significance of timely diagnosis and detection of these lesions, researchers are presently motivated to undertake further investigations. The aim of the present study was to assess the amount of serum alpha-tocopherol in patients with DC and compare it with that of normal, healthy individuals. Methods A total sample size of n=34 was included in the current study. Group A, designated as the control group, comprised 17 randomly selected healthy subjects, while Group B, the DC diagnostic group, consisted of 17 patients. Blood samples were collected, and the concentration of vitamin E or alpha-tocopherol was evaluated and expressed in mg/mL. Results Compared to the mean vitamin E level in healthy controls (12.08 ± 1.92 mg/mL), patients with DC showed a statistically significant (p<0.0001) reduction in mean vitamin E levels (5.29 ± 1.01 mg/mL). Conclusion Patients with DC have lower levels of vitamin E than healthy individuals. The reduced concentration of vitamin E can have a role in the extension of cystic volume and thus have an impact on the aggressiveness of pathologic lesions. The therapeutic benefits of vitamin E supplementation in reducing the aggressiveness of DC should be evaluated in future research.
RESUMEN
Background Gender determination is critical to forensic science and medico-legal applications. Given that it is the most dimorphic bone in the skull and is frequently found intact, the mandibular bone may be extremely important in determining gender. Orthopantomograms (OPGs) are quite helpful in accurately estimating age and sex in this regard. It is a laborious task for forensics to determine the gender of victims of mass casualties, natural disasters, and severely dismembered bodies. The mandible, which is susceptible to development spurts, has a high degree of accuracy for determining sex. Aim This study aims to evaluate the potential use of coronoid height and condylar height as reliable anatomical markers for determining gender. Materials and methods In this study, 100 samples were used as study samples, 50 of which were male and 50 of which were female, in the age group of 20-30 years. The OPGs were obtained using a Planmeca Promax Scara 3 Digital OPG Machine (Planmeca, Helsinki, Finland), with settings of 70 kVp, 8 mA for 0.9 seconds, ensuring a 1:1 ratio. The images were then transferred to Planmeca Romexis® Viewer Software, Version 6.0 (Planmeca Oy, Helsinki, Finland) for measurement recording. Results Descriptive statistical analysis was done for this study and discriminant analysis was also done to create a population-specific formula. Results showed that the standard mean error for males concerning condylar height was 2.3 and coronoid height was 0.7. The standard mean error for females by condylar height was 1.6 and coronoid height was 0.6. The p-value was significant for coronoid height in both males and females. The p-value was not clinically significant for condylar height in both males and females. Conclusion The study's findings indicate that a larger mandibular angle is advantageous for gender assessment and helps with gender dimorphism. Out of both the parameters evaluated, coronoid height has shown statistical significance in both males and females. Hence, the study concludes that the parameter, coronoid height can be utilized to assess the gender of an individual.
RESUMEN
Oral cancer is among the highest in the Indian subcontinent. Advanced stages of oral cancer are associated with severe morbidity and higher mortality. Salivary diagnosis is novel and non-invasive. It could be employed on patients even with restricted mouth opening. Hence, an attempt was made to retrieve relevant data regarding this clinically relevant topic. This article has reviewed metal oxide nanoparticles as a biosensor (BS) in salivary diagnosis for oral cancer. Gold, copper oxide, and carbon nanotubes (CNTs) were used in BS applications. A search from the PUBMED database collection (2004 to 2024) was performed to identify the nanoparticle biomarkers and salivary diagnosis in oral cancer. It revealed 30 articles. All the relevant data was extracted and tabulated in this review. We have discussed the relevance of these BS in salivary diagnosis with their corresponding clinical parameters and sensitivity. We hope that this review summarizes the available literature on this topic and incites dedicated research in prompt and early diagnosis of oral cancer, which directly influences the quality of life outcomes in such patients.
RESUMEN
Forensic anthropology and forensic medicine both have been fascinating fields that deal with mandibular characteristics and sex determination. Researchers may determine an individual's biological sex with amazing precision by examining the size, shape, and proportions of the mandible. This information is useful for anthropological studies and criminal investigations. This systematic review aims to evaluate the consistency and validity of using mandibles as a method for gender determination across different populations. A systematic search was conducted in PubMed, Web of Science, and Scopus databases. Further, a manual search was carried out to find additional studies. Mandibular parameters and other relevant data about research were extracted from the included studies. Random effects meta-analysis was carried out for four parameters. A total of nine studies were included in the systematic review out of 76 initial search results. All studies were in vitro. Nine studies were included in the qualitative analysis, whereas only seven studies were included in the meta-analysis. A total of 2385 individuals (1193 male and 1192 female) were evaluated in the included studies. The parameters assessed were as follows: minimum ramus breadth (MiRB), maximum ramus breadth (MaRB), projective ramus height (PRH), bigonial width (BGW), gonial angle (GA), and antegonial angle (AGA). Meta-analysis was conducted for four parameters out of six. For the two parameters, meta-analysis was not conducted as only one study was evaluated. Meta-analyses of PRH obtained a high degree of heterogeneity (99%), mean difference (MD) of 4.06 mm, and p-value of p=0.09. Meta-analysis of BGW obtained 93% heterogeneity, MD of 9.03 mm, and p=0.0007. Meta-analysis of GA showed 99% heterogeneity, MD of 3.44 mm, and p=0.66. Meta-analysis of AGA obtained a low heterogeneity of 30%, MD of -0.77 mm, and p=0.23. The parameter, BGW, can be considered a useful tool in identifying sex. The parameters, PRH, GA, and AGA, cannot be preferred as a reliable tool in identifying the sex of an individual in forensic contexts.
RESUMEN
BACKGROUND AND AIM: Oral squamous cell carcinoma (OSCC) is among the leading top three cancers in India. However, recent literature has shown an increase in the rise of oral cancer in younger individuals without any history of tobacco-related habits. Chronic mucosal irritation (CMI) has been noted to have a substantial impact on the development and etiology of OSCC. With the shift in the trend, it is imperative to observe and monitor alterations associated with its etiological factors. The study aims to evaluate the prevalence and clinical characteristics of OSCC patients and the association of these parameters in cases with and without tobacco usage. METHODOLOGY: A retrospective study spanning a period of 10 years was done on histopathologically diagnosed cases of OSCC. Various clinicopathological characteristics were collected from patient records, including demographic features, tobacco-related habits, including tobacco chewing and smoking, clinical presentation, anatomic sites, and histopathological grading based on the inclusion and exclusion criteria. The data were tabulated to Microsoft Excel (Microsoft Corporation, Redmond, WA), and descriptive statistics analysis and chi-square test of significance were applied to the data using IBM SPSS Statistics (version 29.0.2; IBM Corp., Armonk, NY). The study correlated the epidemiologic behavior of OSCC with age, gender, site, and tobacco-related habits. RESULTS: This study included a sample size of 204 (72 females & 132 males). Tobacco-related habit-associated cases were 98 (48.5%) and without tobacco habits were 61 cases (29.6%). Etiology associated with CMI emerged to be a significant tooth-related factor. Out of 72 females, 32 (44.4%) of the females were without habit. OSCC caused by trauma from CMI was analyzed in 40 cases (19.6%) and 22 (55%) were females. The majority of lesions (76 (37.4%) cases) presented on the lateral border of the tongue. Among the OSCC patients with a history of chronic mechanical irritation, 37 (48.7%) cases were observed to be specifically on the lateral border of the tongue. CONCLUSION: These 10-year data will generate awareness about the disease pattern occurring within a community and provide an overview of the prerequisite of considering CMI as an etiological factor for the development of OSCC without the association of tobacco-related habits.
RESUMEN
Aim This study aims to evaluate the non-morphological traits of the South Indian population. Introduction Dental morphological traits, also known as non-metric dental traits, exhibit variation in appearance both within and between groups. The study analyzed the non-metric traits among the South Indian population, as few variants can be grouped within the population. Materials and methods A total of 500 extracted tooth samples were collected. The dental non-metric traits that were evaluated are the cusp of Carabelli (CC), Talon's cusp (TC), shoveled incisor (SI), peg-shaped lateral incisor (PL), protostylid (PR), Dryopithecus pattern groove (DP), hypoconulid (HY), parastyle (PA), multiple parastyle (MPA), paracone (PC), Bushman's canine (BC), interruption groove (IG), tuberculum dentale (TD), tuberculum intermedium (TI), radix entomolaris (RE), fusion (F), radiculous premolar (RP), dilaceration (D), dens evaginatus (DE), and enamel pearl (EP). Results Out of 20 dental non-metric traits that were evaluated in the study, 14 traits were identified to be common within the population. The prevalence were as follows: cusp of Carabelli (52%), shoveled incisor (8.2%), peg-shaped lateral incisor (7.4%), parastyle (0.8%), multiple parastyle (0.2%), Bushman's canine (0.4%), interruption groove (2.2%), tuberculum intermedium (0.6%), radix entomolaris (39.6%), fusion (2.8%), radiculous premolar (0.2%), dilaceration (58.2%), dens evaginatus (1.2%), and enamel pearl (0.8%) among the South Indian population. Conclusion The current study was discovered to have more Carabelli traits, shoveled incisors, radix entomolaris, and dilaceration than other non-metric features. This shows that these characteristics are more prevalent in the South Indian population, which could be one of the strategies used to validate human identification in a forensic context.
RESUMEN
Background Dental enamel, the outermost layer of the tooth, stands as a unique and remarkable tissue that plays a crucial role in safeguarding teeth against various external factors. The examination and analysis of enamel rod end patterns on tooth surfaces, referred to as ameloglyphics, offer a promising avenue for dental identification and forensic investigations in forensic medicine, thereby enhancing the precision and reliability of forensic analyses. This paper aims to evaluate and compare the ameloglyphics of different species under a stereomicroscope. The species examined in this study include the beaver (genus Castor), fox (genus Vulpes), and human (Homo sapiens). Methods Teeth samples from each species (n = 3) were gathered from the tooth repository and examined under a stereomicroscope at various magnifications, both with and without graphite staining. Photographs were captured, and the enamel patterns were meticulously evaluated. Through the utilization of plot profiles, the enamel patterns of the different species were compared, and any discernible differences between them were carefully noted. Results The plot profiles of the three species were analyzed, revealing distinct characteristics. Specifically, it was observed that the plots of the genus Castor teeth and Homo sapiens teeth exhibited dispersed arrangements, whereas the plot profile of the genus Vulpes displayed a closely arranged pattern. Conclusions Within the confines of the current investigation, it can be inferred that every mammal exhibits a distinct and exclusive arrangement of enamel rods. Hence, the task of identifying a deceased individual through dental imprints may pose difficulties if the structural characteristics are not thoroughly comprehended.
RESUMEN
Background Studies evaluating the quality of life (QoL) among oral cancer patients in the Indian population are scarce. Regular follow-ups and QoL assessment in oral squamous cell carcinoma (OSCC) patients can aid in comprehensive support strategies to improve their QoL outcomes. Aim and objectives This study aimed to assess the QoL of oral cancer patients and correlate the QoL with demographic and treatment parameters. Materials and methods The study included oral cancer patients who had previously reported to the Department of Oral and Maxillofacial Surgery. QoL assessment was done using the EORTC QLQ-C30 and QLQ-HN43 questionnaires before and after treatment. The clinico-demographic details, treatment data, follow-up data, and recorded mean QoL were procured from the patient records in Dental Information Archival Software. Assessment of QoL was done before treatment and at intervals of one month, three months, six months, 12 months, 24 months, and 36 months postoperatively after treatment. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 23 (released 2015; IBM Corp., Armonk, New York, United States). A repeated measures analysis of variance (ANOVA) was utilized for comparing the average QoL scores and frequency of follow-ups across various intervals. Chi-square tests assessed differences in mean QoL among genders, across different sites, and between primary closure and graft placement. The significance was set at a p-value of less than 0.05. Results A total of 90 OSCC patients had reported to the department. A preoperative assessment of QoL was done for 90 (100%) patients. Out of these patients, surgery has been performed on 41 (45%). Twenty-five out of 41 (60%) patients had responded to regular follow-up, and QoL was assessed for these patients. After the immediate postoperative phase, only 12 (48%) had reported after three months. Only six (24%) had a 12-month follow-up, five (20%) had a two-year follow-up, and one (4%) had a three-year follow-up. There was a constant decrease in the number of follow-ups after the treatment of OSCC (p=0.00). Prior to treatment, the mean QoL index was 4.64. Females had a slightly higher preoperative QoL of 4.76 compared to males, with a score of 4.67 (p=0.157). Immediately after the treatment of OSCC, a decline in QoL scores was noted, with a mean score of 4.25 (p=0.32). Patients who underwent primary closure after excision had a mean post-op QoL score of 4.9, while patients who underwent graft placement had a mean score of 4.6 (p=0.157). Conclusion This study highlights the enduring impact of oral cancer on a patient's quality of life and emphasizes the need for ongoing research to explore specific interventions that can contribute to sustained improvement in QoL. It emphasizes personalized, holistic care approaches for such patients.
RESUMEN
Background Head and neck bone pathologies cover various conditions with diverse causes. Infections like osteomyelitis and dental abscesses can spread to soft tissues and bones, causing tissue death, inflammation, and systemic effects. Benign and malignant tumors can develop from soft tissue, cartilage, or bone, posing challenges for diagnosis and treatment. Studies on their prevalence in local populations are rare, obscuring our understanding of regional health dynamics. Aim In this study, we aimed to assess the prevalence of bone pathologies documented over the last three years from 2021 to 2023. Materials and methods Histopathologically confirmed cases of bone pathologies at Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai, India, were gathered from the institutional database (DIAS: Dental Information Archiving Software) from January 1, 2021, to December 31, 2023. They were categorized into groups of infectious and inflammatory lesions, fibro-osseous lesions, malignancies originating from bone, malignancies invading bone, and miscellaneous conditions. The data was then compiled into a Google spreadsheet (Google, Inc., Mountain View, USA) for further analysis. Graphs were created to visualize the prevalence of bone pathologies enabling a descriptive exploration of temporal trends. Results A total of 2626 biopsy records were reviewed. Among these, 242 (9.21%) cases of bone-related pathologies were included, and the remaining 2384 (90.79%) entities without any mention of bone were excluded. Overall, considering all three years, 43.8% (100) bone-related lesions were reported in 2021, 30.3% (77) in 2022 and 25.9% (65) in the year 2023. Under each category, infectious and inflammatory lesions for 40.5% (98), fibro-osseous lesions for 14.9% (36), benign lesions for 2.9% (7), malignancies originating from bone for 1.7% (4), malignancies invading bone for 38% (93), and miscellaneous conditions for 1.65% (4) were reported. The highest number of infectious and inflammatory pathologies (53%) were reported in 2021. A steep fall was observed in 2022 and 2023 under the infectious and inflammatory category. The malignancies invading the bone showed almost similar distribution in all three years. Conclusion The observed variations highlight the unpredictability of bone pathologies, involving the jaw bones. We emphasize continuous observation and analysis to comprehend changing patterns in bone health.

RESUMEN
Background Enamel etching is of utmost importance during the orthodontic bonding procedure. Phosphoric acid, hydrofluoric acid, and citric acid are used in specific concentrations to create surface irregularities on enamel surfaces, enhancing the bond strength of the orthodontic attachment. Therefore, it is essential to evaluate the type of etchant for reliable orthodontic bracket bonding with minimal damage to the enamel surface. Aims and objectives This study aimed to investigate the morphological changes on the enamel surface after treatment with different surface etchants, assess the depth of penetration, and evaluate the shear bond strength (SBS) of orthodontic brackets. Materials and methods One hundred and one extracted premolar teeth were used to investigate morphological changes on the enamel surface treated with 37% phosphoric acid, 11% hydrofluoric acid, and 20% citric acid. It was evaluated on a scanning electron microscope (Jeol Scientific Equipment, Jeol Limited, Akishima, Japan), and the SBS of brackets on enamel treated with different etching agents was evaluated using an Instron Universal Testing Machine (UTM; Instron Model: 5982, Universal Testing Systems, Norwood, MA). Group A had 60 test samples. Group B had 40 test samples. One control without any acid etching was used in both groups. Subgroup A1 (n = 30) was evaluated for surface characteristics of acid-etched enamel. Subgroup A2 was assessed for the penetration depth of various etchants. Group B (n = 40) was tested for SBS. The results were tabulated and analyzed using IBM SPSS Statistics, version 20.0 (IBM Corp., Armonk, NY). Post hoc Tukey HSD test and one-way analysis of variance were used to assess SBS and penetration depth of etchants (P ≤ 0.05). Pearson's correlation test was used to correlate SBS, etching pattern, and penetration depth. The chi-square test was used to test the frequency of types of etching patterns. Results Intergroup correlations between etching depth, etching pattern evaluated on SEM, and SBS evaluated on the UTM showed a high statistical correlation between etching depth & SBS, etching depth & etching pattern, and SBS & etching pattern between A1, A2, and group B (P ≤ 0.001). A highly significant negative correlation between SBS & etching pattern (P = 0.42) was observed among intra-group correlation. Non-significant correlations were found between etching depth & SBS and etching depth & etching pattern within the 20% citric acid etch group (P = 0.370 and 0.141, respectively). Conclusion Penetration depth obtained was highest with 11% hydrofluoric acid, followed by 37% phosphoric acid and 20% citric acid. In addition, 11% hydrofluoric acid showed the highest bond strength. Acid etching showed better penetration depth and bond strength than control.
RESUMEN
Background Oral surgical records contain all the information regarding a patient, including their history, clinical findings, diagnostic test results, pre-and postoperative care, progress, and medication. Notes that are properly drafted will help the physician argue that the course of therapy is appropriate. Several tools have been created for auditing clinical records; one such tool that may be used for any inpatient specialty is the CRABEL score system developed by CRAwford-BEresford-Lafferty. Aims This research aimed to evaluate the oral surgical records using the CRABEL scoring system for quality assessment. Materials and methods The case audit was performed from June 2023 to February 2024 for all Excisional biopsy cases of Oral Squamous Cell Carcinoma. Relevant data was retrieved from the Dental Information Archival Software (DIAS) of Saveetha Dental College and Hospitals, Chennai. It was evaluated by two independent oral pathologists trained in CRABEL scores. Two consecutive case records were evaluated. Fifty points were given for each case record. Scoring was given according to initial clerking (10 points), subsequent entries (30 points), consent (5 points), and discharge summary (5 points). The total score was calculated by subtracting the total deduction from 100 to give the final score. The mean scores of the case records were calculated. A descriptive statistical analysis was done with Statistical Package for Social Sciences (SPSS version 23.0; IBM Inc., Armonk, New York). Inter-observer agreement and reliability assessment were made using Kappa statistics. Results From the DIAS in that period, the data of 52 cases were retrieved and reviewed. There was no proof of a reference source in the audited records, and one deduction was made to the reference score in the initial clerking, and the effective score was 98 out of 100. The mean values of 52 case records were also 98 out of 100. The observed kappa score was 1.0. There was no inter-observer bias in the scoring criteria. Both observers also gave the same scoring. Conclusion Our study illustrates that oral surgery case records in our institution were found to be accurate, as they maintained 98% of the CRABEL score value. Frequent audit cycles will help in standardizing and maintaining the quality of oral surgery case records.
RESUMEN
The supracrestal tissue attachment (SCTA) is the new terminology for biologic width. SCTA is defined as the physiologic dimension of a solitary functional unit composed of junctional epithelium and connective tissue attachment. Its preservation is critical for the well-being of periodontal health. SCTA has been widely studied and scientific literature is indicative of its significance during the placement of restoration, including prosthetic crowns. This should be taken care of in cases of anterior teeth within the smile zone, where dental crowns are regularly placed subgingivally for aesthetic reasons. In addition, any violation of SCTA while restoring the dentition will present as gingival inflammation and pain, consequently, leading to failure of the clinical procedure.
RESUMEN
Background and aim Orofacial neuropathic pain is a medical condition caused by a lesion or dysfunction of the nervous system and is one of the most challenging for dental clinicians to diagnose. Anticonvulsants, antidepressants, analgesics, nonsteroidal anti-inflammatory drugs, and other classes of medications are frequently used to treat this condition. Our study aimed to build a machine learning-based classifier to predict the need for anticonvulsant drugs in patients with orofacial neuropathic pain. Materials and methods A machine learning tool that was trained and tested on patients for predicting and detecting algorithms, which would in turn predict the need for anticonvulsants in the treatment of orofacial neuropathic pain, was employed in this study. Results Three machine learning algorithms successfully detected and predicted the need for anticonvulsants to treat patients with orofacial neuropathic pain. All three models showed a high accuracy, that is, 97%, 94%, and 89%, in predicting the need for anticonvulsants. Conclusion Machine learning algorithms can accurately predict the need for anticonvulsant drugs for treating orofacial neuropathic pain. Further research is needed to validate these findings using larger sample sizes and imaging modalities.
RESUMEN
BACKGROUND: Assessment of awareness levels about any hospital is critical to judge its current standings and plan for future development. Limited literature is available about dental health in Libya. AIM: This study aimed to study the awareness and perception of the various specialty services offered by the Faculty of Dentistry (SDC), Sebha University for their quality and preference. MATERIALS AND METHODS: It was a performance monitoring research, and the data was collected by interview using a standardized questionnaire. Non-probability judgmental sampling was used. The offered services included all specialties in dentistry and oral cancer screening. Information relating to the awareness and perception of SDC specialty services was collected with few agree/disagree questions from 450 subjects. Data was collected, tabulated, and analyzed with descriptive statistics using SPSS v23.0 (IBM, Armonk, NY, USA). RESULTS: About 22.7% (n=102) were in the 45-54 years age group. Self-employed (n=108, 24%) and professional (n=108, 24%) were noted in occupation. Forty-eight (n=216) were graduates. Three hundred twenty-eight respondents (72.9%) were aware about the dental services. Four hundred twenty-eight respondents (95.1%) have visited SDC. Three hundred six respondents (68%) were satisfied, and 66 respondents (14.7%) were very much satisfied. Dental health checkups were predominantly known to the respondents (n=302, 67%). For all the other specialties, the awareness level was low. CONCLUSION: The identification of weak areas is crucial for the future planning and development of oral health care rendered by SDC.
RESUMEN
Background Forensic odontology has emerged as a crucial method for identifying skeletal or dental remains. Due to the restricted accuracy of current techniques for estimating age at death, researchers have endeavored to illustrate age-related alterations in dental hard tissues. Bone remodeling constitutes an ongoing and intricate process throughout our lifespan. It is believed that morphological changes in the mandible during an individual's lifetime are influenced by both dental condition and the individual's age. Objectives This study aims to evaluate the efficacy of mandibular parameters such as projective ramus height (PRH), maximum ramus breadth (MaRB), bigonial width (BGW), antegonial depth (Ant.D), and antegonial angle (Ant.A), as a gender-determining tool and compare and analyze the mandibular parameter measurements using digital orthopantomography. Methodology In this study, the total number of samples used was 500 out of which 250 were males and 250 were females. Planmeca software (Version 6.0, Planmeca Romexis, Charlotte, NC) was used and the accuracy test, analysis of variance (ANOVA), multiple regression, and discriminant analysis for gender were performed using SPSS for Windows, Version 16.0 (SPSS Inc., Chicago, IL). Results For age estimation, the least standard error of 0.008 was observed for BGW. A maximum standard error of 0.230 was observed for Ant.D. For sex determination, the coefficient function was positive for PRH, BGW, and Ant.A, with values of 0.202, 0.805, and 0.052, respectively. Ant.D and MaRB both exhibited negative values of -0.204 and -0.379, respectively. Conclusions Out of all the parameters assessed, BGW is the most preferred parameter for age estimation and Ant.A can be preferred for sex estimation. Age and gender can be estimated using the two parameters in the Indian population.
RESUMEN
Pemphigus vulgaris (PV) is a chronic autoimmune blistering disorder characterized by the loss of intraepithelial adhesion affecting the skin and mucous membranes, predominantly affects females in their fifth and sixth decades of life. Due to its rare occurrence in children and adolescents, there is often a delay in diagnosis and treatment in this age group. PV should always be considered in the differential diagnosis of oral ulcerative and vesiculobullous lesions in both children and adolescents.
