Evaluation of Salivary Butylated Hydroxytoluene and Ascorbic Acid Levels in Type 2 Diabetes Mellitus Patients

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a global health concern associated with systemic as well as oral complications. The preventive antioxidants found in saliva naturally reduce the damaging effects of reactive oxygen molecules. Any disruption to the regular functioning of these antioxidants may lead to oxidative stress, which could boost an individual's vulnerability to oral diseases. Diabetes patients are vulnerable to various dental complications, such as oral mucosal disorders, dental caries, dry mouth, and periodontal disease.

AIM

This study aimed to assess the salivary butylated hydroxytoluene (BHT) and ascorbic acid (AA) levels in patients with controlled and uncontrolled type 2 diabetes mellitus.

MATERIALS AND METHODS

The present study included samples from patients aged 45-65. Group I consisted of 20 controlled diabetic patients, and Group II consisted of 20 uncontrolled diabetic patients. Unstimulated whole saliva samples were collected from both groups, and laboratory analysis was done. Salivary BHT and AA levels were quantified using enzyme-linked immunosorbent assay (ELISA) and spectrophotometric assay.

RESULTS

Salivary butylated hydroxytoluene levels were found to be higher in the uncontrolled diabetic group than in the controlled diabetic group, and salivary AA levels were found to be higher in the controlled diabetic group than in the uncontrolled diabetic group. The mean ± standard deviation (SD) values of butylated hydroxytoluene among controlled and uncontrolled diabetic patients were 2.98 ± 0.12 and 2.99 ± 0.11 absorbance units, respectively. The mean ± SD value of AA in the controlled group was found to be 2.99 ± 0.15 absorbance units, and the mean ± SD value of AA in the uncontrolled group was 2.64 ± 0.96 absorbance units. However, it has been found that there is no statistically significant difference between salivary BHT and AA levels among controlled and uncontrolled diabetics, with p-values of 0.867 and 0.419, respectively.

CONCLUSION

Values of salivary biochemical markers were distinctly different between controlled and uncontrolled diabetic groups. However, to establish a definite role of salivary BHT and AA levels as biomarkers in managing and monitoring type 2 diabetes, future studies are required, even though the trends exhibit possible alterations in biomarkers.

Bone Trabecular Pattern Analysis in Odontogenic Cysts Using Cone Beam Computed Tomography: A Clinical Retrospective Study

Introduction The cysts of the maxillofacial region account for one of the most common pathologies of the head and neck region after the mucosal pathologies. Radiography provides an essential clue in early diagnosis and triaging, but it continues further as it is used to evaluate the post-treatment outcome. However, manual analysis is prone to errors. In this scenario, fractal analysis (FA) in radiographs uses mathematical methods to analyse the changes in grey scales in a given radiographic image. FA in odontogenic cysts is used to characterise their complexity, uncover hidden patterns, monitor treatment response, and potentially provide prognostic information. This paper aimed to assess the fractal characteristics of the radicular cyst (RC), dentigerous cyst (DC), and odontogenic keratocyst (OKC) using cone beam computed tomography (CBCT). The objective was to calculate fractal dimension (FD) values expressed in each of these cysts, which could prove to be a radiological adjunct in diagnosing the above cysts. Materials and methods As this is a retrospective study, the archives of CBCT images from June 2021 to December 2023 were obtained from patients diagnosed and confirmed with a histopathological diagnosis with RC, DC, and OKC. The FA was performed using Image J Software (Ver 1.51, National Institute of Health Bethesda, Fiji). The cortical and cancellous bones were segmented using thresholding techniques and converted to binary images. The mean FD of the three planes was then compared to establish the distinctive fractal characteristic for the specific odontogenic cysts. A one-way ANOVA was performed using the Statistical Product and Service Solutions (SPSS) (version 23.0; IBM SPSS Statistics for Windows, Armonk, NY) to determine the difference between FD values of RC, DC, and OKC with a significance level less than 0.05. Results The FD values of DC, RC, and OKC were 1.33 ± 0.17, 1.08 ± 0.16, and 1.65 ± 0.12, respectively. The results indicated that OKC had higher FD values than DC and RC, which means that OKC had lesser bone destruction compared to DC and RC. Inferential statistics showed that the one-way ANOVA was used to compare the means of the three groups of FD data. When calculated for the three groups, the F-statistic value was at 7.29, which yielded a P value of 0.03, making it statistically significant for a 95% confidence interval (p<0.05). Conclusion Our CBCT study on bone trabecular pattern analysis using FD and FA in odontogenic cysts reveals distinct alterations in bone parameters among different cyst types. The probability of higher FD values in OKC is because of lesser cortical bone destruction in OKC compared to the other cyst types. These findings have potential implications for diagnosing, treating, and prognosticating odontogenic cysts.

Prevalence of Keratosis in the Oral Cavity: A Clinical Retrospective Study

INTRODUCTION

A lesion in the oral cavity can appear clinically white due to an increase in keratin (hyperkeratosis), an increase in the thickness of the spongiotic cells (acanthosis), accumulation of fluid within the epithelium, and formation of the pseudomembrane. There are several innocuous white lesions, while only a few require aggressive management. The lesions of frictional keratosis, tobacco pouch keratosis, and morsicatio buccarum (MB) are innocuous white lesions that can be treated with simple treatments. This paper aimed to study the prevalence of the three white lesions among the patients visiting Saveetha Dental College. The objectives were to study the gender prevalence of the lesions and the average age distribution of these lesions.

METHODOLOGY

The study was a retrospective clinical study that collected data from DIAS (Digital Information and Archiving Software) over four years among the patients visiting Saveetha Dental College. The inclusion and exclusion criteria were based on the clinical diagnostic features, and the existence of any other oral potentially malignant disorder made the exclusion criteria. The collected data were entered into Statistical Package for the Social Sciences (SPSS) version 26.0 (IBM Corp., Armonk, NY). The data were analyzed for descriptive and inferential statistics.

RESULTS

The total number of patients with the lesions mentioned above was 5,613, with an average age of 37.28 years. The most common lesion was frictional keratosis with 4,026 patients, followed by tobacco pouch keratosis with 1,537 patients. The least common was MB, with 54 patients. Based on gender, all of the above lesions were most commonly seen in men. The age analysis revealed that frictional keratosis and MB were seen in middle age, while tobacco pouch keratosis was seen in middle to old age.

DISCUSSION

From the above study, it is noticed that frictional keratosis was the most common lesion, which had arisen most commonly in the third molar region and was seen in the younger age group due to the eruption of the third molars. Among the lesions, the only tobacco-induced lesion was tobacco pouch keratosis, which was seen predominantly in middle to old age, implying that prolonged habit usage was essential for the lesion to develop.

CONCLUSION

This study has helped us understand the prevalence of innocuous keratotic lesions in the South Indian population. The findings of this study will give a guideline for confirming the clinical diagnosis of similar lesions. This could potentially reduce the need for undertaking a biopsy and rather try treating with less invasive modalities, and when no response is seen, then it would be worthwhile to do a biopsy.

Prevalence of Aphthous Stomatitis: A Cross-Sectional Epidemiological Study

Introduction Recurrent aphthous stomatitis (RAS) is a common ulcer of idiopathic etiology but is recurrent, causing painful ulcers in the non-keratinized mucosa. The disease is commonly seen in people aged 10-40 years. The etiology of RAS has yet to be well established, but several risk factors that lead to the development of RAS have been proven in the literature. With an unknown etiology, developing a definitive cure and maintaining disease remission remains challenging. An epidemiological survey will shed some light on the disease's prevalence, which could provide insights into disease management. This study aimed to study the prevalence of aphthous stomatitis among the patients visiting the dental outpatient services of a dental college in South India. The objectives were to discover the different subtypes of aphthous stomatitis and the age predominance of the type of ulcer. Materials and methods The data was collected from the case records of Saveetha Dental College and Hospitals, Chennai, India, dated from June 2019 to June 2023. The age and gender of the patients with RAS were recorded. The details collected were systematically arranged in an Excel sheet (Microsoft Corporation, Redmond, Washington, United States) and further analyzed using IBM SPSS Statistics for Windows, Version 24.0 (Released 2016; IBM Corp., Armonk, New York, United States) and chi-square tests were run to check for statistical significance. Results A total of 1,44,056 patients visited the Dental OPD during the study period. Of these, 1115 patients had RAS. When the data was analyzed, there was a three-fold increase in the occurrence of RAS during the coronavirus disease 2019 (COVID-19) pandemic, which was statistically significant (p=0.043). The most commonly affected age group was 26-40 years. Among the clinical variants of RAS, it was found that 82.5% of RAS patients had a minor variant of aphthous stomatitis. Conclusion This study shows the prevalence of different types of aphthous stomatitis, wherein we noticed that the minor clinical variant was the most common, followed by the major variant. The lesions were more commonly seen in women. However, the age group most commonly affected was 26-40 years.

A Painless Bump: A Case Report of Cemento-Ossifying Fibroma of the Anterior Maxilla

Cemento-ossifying fibroma (COF) is a benign odontogenic neoplasm. It is considered an ossifying fibroma with traces of interspersed cementum fragments. Here we present a case report of the occurrence of COF in the maxillary anterior region of an elderly woman. A 61-year-old female reported with a painless, progressive, slow-growing swelling on the upper front jaw region for the past five years. A single, localized, swelling on the anterior region of the maxilla which was non-tender and bony hard in consistency. Radiological examination consisting of orthopantomagram (OPG) and cone-beam computed tomography (CBCT) revealed increased thickness of bone over frontal, parietal and maxilla with alteration of trabecular pattern - cotton wool/ground glass. Serum alkaline phosphatase level was found to be 865 U/l, however, serum calcium level and other routine blood investigations (hemogram) were within normal limits. The above radiological and laboratory findings are more in favour of primary bone pathology and with a biopsy later correlating with histopathological findings; it was diagnosed as COF. Under conscious sedation, surgical excision of the bony mass was done along with extraction of associated teeth. The patient is currently on regular follow-up and planning for a dental prosthesis is in progress.

Prevalence of pulp stones in IOPA radiographs

The presence of calcifications or hard deposits within the pulp chamber of the teeth is referred to as pulp stones. There is a geographic and ethnic variation in the occurrence of these calcifications in the population. The article assessed the occurrence of pulp stones. As a secondary objective, the gender or age difference was also assessed. This study was carried out retrospectively by analyzing the archived dental radiographs. A total of 100 radiographs were taken for the analysis based on random sampling. The selected samples were scanned for the occurrence of pulp stones. From a total of 100 subjects, 15% had more than one pulp stone. This study revealed the prevalence of dental stones in the sample population was low. However, of the teeth examined, the mandibular arch had a higher incidence when compared to the maxillary arch. No significant correlation was found among gender or age. Further studies on a larger scale are required to find possible associations that would help determine clinical outcomes.

Prevalence of Errors in Fundamentals of Patient Positioning in Digital OrthopantomogramA Retrospective Study

Introduction: Digital panoramic radiograph or Orthopantomogram (OPG) has become an indispensable equipment in oral disease diagnosis. However, it is prone for positioning errors in digital imaging systems that affect quality of dental care. Aim: To assess the prevalence of errors in patient positioning in digital OPG. Materials and methods: This retrospective study including 900 digital OPG’s (483 males and 417 females) which were collected from the Department or Oral Medicine and Radiology at Saveetha Dental college and hospital, Chennai, Tamil Nadu, India. Digital OPG images taken during the month of January from 1.1.2021 to 31.1.2021 were retrospectively collected and used for this study. The data was then analyzed and interpreted in the consecutive months from 1.2.2021 to 31.3.2021. The images were assessed for the frequency of positioning errors by a single radiologist and its association with the patient gender. The results were statistically analysed using Statistical Analysis of the Social Sciences (SPSS) 23.0 software. Chi-square test was used for the statistical analyses to determine the association between positioning errors and gender (p-value ≤0.05). Results: Among the positioning errors, the most common error was “head too far forward”, 19.9% in males and 23.5% in females. The least common errors seen were excessive downward angulation and upward over-angulation 27 (5.6%) and 16 (3.3%) cases in males and 19 (4.6%) and 15 (3.6%) cases in females respectively. The association between gender and positioning errors was found to be statistically significant at p-value 0.001 (p<0.05) with a Chi-square value of 22.455. Conclusion: This study highlights the importance of structured training in taking panoramic radiographs and quality support required for proper image outcome. This is necessary to reduce treatment cost, patient time expenditure, exposure to radiation and delay in treatment planning.

Therapeutic effectiveness of alternative medications in oral lichen planus: A systematic review

Lichen planus is a chronic inflammatory condition affecting the skin and mucosa. The etiology is unknown but the pathogenesis appears to be an immune-mediated reaction. The mainstay drugs used in the treatment are immunomodulators. The aim of this paper is to report on the therapeutic effectiveness of the alternate medications used in the management of oral lichen planus (OLP). A systematic search of PubMed, Web of Science and Cochrane Controlled Clinical trials were done for all the papers published until December 2019. The search resulted in a total of 20 studies that were found suitable for the review. The results showed that the reduction in pain, treatment effectiveness was comparable between the steroids and alternative medications. However, the alternative medications had a therapeutic advantage in studies that had used placebo as controls and the results were statistically significant (P < 0.05). No major adverse effects were reported with the usage of alternative medications. There is definitely a therapeutic potential in the usage of alternative medications in the management of OLP. In terms of therapeutic effectiveness, they are on par with the immunomodulators. These alternative medications offer us a new therapeutic option in the management of OLP without any adverse effects.

Knowledge, Attitude and Practice of Radiation Protection among Dental Students

Radiology is one the key cornerstone of investigation in Dentistry. The application of radiology in Dental practice has grown by leaps and bounds in the years gone by. Along with this there is an increase in the number of radiation hazards.  The effect of  radiation  on  human  beings  is  very  negative. This survey was conducted with the intent of studying the awareness and knowledge of radiation protection in practice. The survey consisted of 10 closed ended questions which were circulated among 100 interns of a dental college. The data collected was entered into microsoft excel and the data was analysed for an association between the gender and the responses using Chi-square analysis. The majority of the participants were females and they believed that radiation causes harm to humans and surprisingly they had also believed that ionised radiation remains suspended in the air after making a radiographic exposure where there was no statistically significant difference between the genders(p>0.05). The questions also assessed whether a clinical examination is advised before a radiographic examination and the majority were of the view it is necessary which was statistically significant(p<0.05). From this study we could infer that students are well aware of the adverse effects of radiation but in terms of safety practices being followed in Dental clinics, there are some pitfalls noticeable.

Mast cell expression in oral lichen planus: A systematic review

Lichen planus is a common chronic, inflammatory, immune-mediated mucocutaneous disorder affecting the skin and mucosa. The role of mast cells in the genesis of lichen planus has been debated. Establishing a definitive part played by mast cells and its degranulation would possibly provide a permanent, cost-effective treatment modality for oral lichen planus (OLP). This review aims to study the expression of mast cells qualitatively and quantitatively in OLP. The research questions were framed to assess the mast cell count, localization within the epithelium basement membrane zone and degranulation of mast cells. We performed a systematic search of PubMed, Medline, Cochrane and Web of Science. We found a total of 120 studies from which 12 were found suitable for the review. There is a marked increase in the number of mast cells in OLP. The mast cells were seen in increased numbers in the epithelial and connective tissue junction at areas of basement membrane disruption. There was also an increase in the degranulation of mast cells. It is evident that there is an increase in the mast cell number in lichen planus and its subsequent degranulation.
