Oral hygiene practice and periodontal status among two tribal population of Telangana state, India- an epidemiological study.

BACKGROUND: The tribes of India have poor periodontal health status due to their isolation, awareness and less accessibility to dental resources. They follow traditional methods of oral hygiene practice, which are found to be inadequate and inaccurate to maintain their good oral health. This study aims to assess the oral hygiene practice, oral hygiene and periodontal status of two tribes residing in Bhadrachalam, Telangana, India. METHODS: Based on accessibility the two tribes Koya and Lambada were included in the study. The total study population consisted of 1000 subjects, with 500 subjects in each group. Using a preformed proforma the oral hygiene practices were recorded for two groups and oral examination was done using Oral Hygiene Index (OHI-S) index and Community Periodontal Index (CPI). RESULTS: The OHI-S ranged between 2.5-3.0 in both the groups. The CPI index scores showed that sextants with calculus, shallow pockets, deep pockets and loss of attachment of 4-5 mm were significantly present in both groups. CONCLUSION: To conclude, though practice of poor oral hygiene and compromised periodontal status was seen among both groups. However, it was more prevalent in Koya. Under these circumstances, implementation of a basic awareness of oral health care programme for these tribes should be a high priority.

Comparison of gender identification using exfoliated cells obtained from toothbrush and miswak: A longitudinal study.

Gender identification plays a pivotal role in forensic medicine. Among the various methods used for gender identification, deoxyribose nucleic acid (DNA) based methods are considered accurate. Exfoliated oral mucosal cells that are harvested from oral hygiene aids can be potentially used for gender identification using real-time polymerase chain rection (PCR). The aim of the present longitudinal study is to assess and compare the efficacy of toothbrush and miswak as potential tools to harvest exfoliated cells for gender identification. Forty healthy volunteers were recruited and asked to clean their teeth using new toothbrush and fresh miswak each day for 4 days. Toothbrush and miswak used by the participants were subjected to DNA analysis immediately, 1st, 2nd and 6th month. The absorbance of DNA samples were quantified and gender identification was done by amplification of sex determining gene-Sex determining region Y gene (SRY) and ALT1 genes using real-time PCR. The number of correct and positive identification for samples at various time points were tabulated and subjected to statistical analysis. Post hoc power analysis showed that the study had a power of 93%. Correct and positive gender identification was observed for the samples (100%) obtained using miswak, for tooth brush it reduced to 95%, 80%, and 35% at the end of 1st, 2nd, and 6th month. The differences seen at the end of 2nd month and 6th month were statistically significant. Miswak is a better tool to harvest exfoliated cells for gender identification when compared to a toothbrush. Hence, miswak can serve as a potential tool in forensic medicine for DNA extraction and subsequently victim identification.

Artificial Intelligence Application in a Case of Mandibular Third Molar Impaction: A Systematic Review of the Literature.

Objective: This systematic review aims to summarize the evidence on the use and applicability of AI in impacted mandibular third molars. Methods: Searches were performed in the following databases: PubMed, Scopus, and Google Scholar. The study protocol is registered at the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY202460081). The retrieved articles were subjected to an exhaustive review based on the inclusion and exclusion criteria for the study. Articles on the use of AI for diagnosis, treatment, and treatment planning in patients with impacted mandibular third molars were included. Results: Twenty-one articles were selected and evaluated using the Scottish Intercollegiate Guidelines Network (SIGN) evidence quality scale. Most of the analyzed studies dealt with using AI to determine the relationship between the mandibular canal and the impacted mandibular third molar. The average quality of the articles included in this review was 2+, which indicated that the level of evidence, according to the SIGN protocol, was B. Conclusions: Compared to human observers, AI models have demonstrated decent performance in determining the morphology, anatomy, and relationship of the impaction with the inferior alveolar nerve canal. However, the prediction of eruptions and future horizons of AI models are still in the early developmental stages. Additional studies estimating the eruption in mixed and permanent dentition are warranted to establish a comprehensive model for identifying, diagnosing, and predicting third molar eruptions and determining the treatment outcomes in the case of impacted teeth. This will help clinicians make better decisions and achieve better treatment outcomes.

Mucoepidermoid Carcinoma of Minor Salivary Gland in a Patient with Asymptomatic Palatal Swelling - A Case Report.

Incidence of abundant minor salivary gland tissues in the posterior part of hard palate surges the likelihood of salivary gland neoplasm especially in this part of the oral cavity. Minor salivary gland tumor accounts for virtually 15% of all the salivary gland neoplasm, wherein mucoepidermoid carcinoma comprises of 35.9%. Current paper reports a case of mucoepidermoid carcinoma of the posterior part of the hard palate which was an incidental finding. It presented as well-defined smooth swelling, the preliminary radiographic investigation revealed no appreciable bony changes and offered an impression of a benign tumor. Histopathological investigation displayed features of mucoepidermoid carcinoma of intermediate grade. The lesion was surgically excised and the patient was under regular follow up for 3years. The paper focus on the magnitude of swift clinical diagnosis of specific lesions, so increasing the survival rate and reducing the morbidity.

Antioxidant effect of spirulina in chronic periodontitis.

BACKGROUND: Production of reactive oxygen species (ROS) by polymorpho nuclear neutrophils occurs in chronic periodontitis. These ROS are mainly involved in bacterial destruction. However, extracellular release of same results in destruction of surrounding tissue. Spirulina, a potent antioxidant when administered sub gingivally in pockets can offer improved results in chronic periodontitis patients. This study was conducted to evaluate the effect of Spirulina when delivered sub gingivally in patients with chronic periodontitis. METHODS: Sixty chronic periodontitis patients were divided into 2 groups. Group I (n = 30) were treated with Scaling and Root planning (SRP) followed by placement of placebo (SRP-P) and in Group II (n = 30) Spirulina microspheres were placed sub gingivally (SRP-S) following SRP. Clinical parameters like bleeding on probing (BOP), clinical attachment level (CAL), gingival index (GI) and probing pocket depth (PPD) were evaluated. Levels of salivary and serum Malondialdehyde (MDA) were estimated using ultra violet spectrophotometer. RESULTS: At baseline, in both groups there was no statistically significant difference in clinical and biochemical parameters. Intra group comparisons of parameters from baseline to 90 days were statistically significant in both groups. After 90 days difference in clinical parameters and salivary MDA levels were statistically significant in SRP-S compared to SRP-P group. Though serum MDA levels were reduced in both groups, they were not significant statistically. CONCLUSIONS: Our study concluded that, local drug delivery of Spirulina adjunctive to SRP has potent antioxidant effect in treatment of chronic periodontitis.

Drug induced oral erythema multiforme: Case report.

INTRODUCTION: Drug induced oral erythema multiforme a rare clinical entity which involves only the lips and oral mucosa without skin involvement. These lesions are difficult in diagnosing with other oral ulcerative lesions with similar clinical manifestations. PATIENT CONCERNS: This article presents 2 case reports of Oral erythema multiforme in which drugs were the precipitating factor. Its etiopathogenesis, differential diagnosis and treatment modalities of the disease is discussed. DIAGNOSIS: Based on patient's complaints, drug history and clinical appearance, provisional diagnosis of drug induced erythema multiforme was considered. INTERVENTION: For case 1, patient was instructed to discontinue usage of drug and prescribed systemic steroid (Prednisolone 10 mg/d) for a week along with germicidal drugs to prevent secondary infection. Medication was tapered to 5 mg/d after first week.For case 2, patient was instructed to discontinue the drug and systemic steroid prednisolone 20 mg /d for 1 week with tapering dose of 10 mg/d for the second week was administered. OUTCOME: For case 1 and case 2 healing of the lesions were evident on third week of follow up. CONCLUSION: Medications should be taken under medical supervision. Over the counter drugs might lead to allergic reactions like drug induced oral erythema multiforme, which is a rare variant and needs to be differentiate from other oral ulcerative lesion for prompt management and follow-up.

Monostotic Fibrous Dysplasia Involving the Mandible: A Case Report.

Fibrous dysplasia (FD) is a skeletal developmental anomaly, which is non-hereditary and idiopathic in origin. It is characterized by the replacement of normal bone with the excess proliferation of fibrous tissue in irregular bony trabeculae. Patients might complain of swelling, pain, or numbness on the affected side. The incidence of monostotic FD (MFD) is four times more than that of polyostotic fibrous dysplasia. In MFD, the maxilla is more commonly affected than the mandible. The clinical behavior and rapid progression of FD renders the treatment challenging. The malignant potential is 0.5% for untreated cases. Here, we present a case of FD involving the mandible. The clinical diagnostic approach, different imaging modalities, and histological examination methods for definitive diagnosis have been elaborated.

Monoradicular primary mandibular first molar: A rare case in Aseer Province of Saudi Arabia.

Morphological variations can occur in primary and permanent teeth. Genetic and environmental factors could be responsible for various dental anomalies. Anomalous teeth are usually asymptomatic and are diagnosed during routine oral examination. These anomalies may increase caries susceptibility and complicate dental treatment procedures such as extraction or root canal treatment. We report a rare case of mandibular first molar with a single root and a root canal.

Evaluation of Clinical and Radiographic Parameters as Dental Indicators for Postmenopausal Osteoporosis.

PURPOSE: In the early stages, osteoporosis is relatively a silent disease characterised by low bone density with microarchitectural deterioration of the bone tissue leading to enhanced bone fragility. The objective of this study was to evaluate the relationship between age, body mass index, oral signs, and osteoporosis among postmenopausal women. MATERIALS AND METHODS: The study included postmenopausal women who were divided into two groups of subjects. The osteoporotic group comprised 30 patients with osteoporosis who were diagnosed using dual-energy X-ray absorptiometry, and the non-osteoporotic group (control group) comprised 30 subjects with no evidence of osteoporosis. Panoramic radiography was performed, followed by the acquisition of two direct digital intraoral periapical radiographs from the mandibular premolar-molar region. RESULTS: Chi-square test revealed a statistically significant difference (p = 0.001) in the mandibular cortical shape index between the two groups. However, a statistically non-significant difference in cortical width, the panoramic mandibular index, mandibular alveolar bone resorption degree, fractal dimension, and mean number of teeth was found between the two groups. A statistically significant difference was observed in the mean age between the osteoporotic and non-osteoporotic groups. CONCLUSION: The mandibular cortical index findings (MCI) on panoramic radiograph are effective indicators of osseous changes in postmenopausal osteoporosis, thereby determining early prediction of osteoporotic fracture risk and reducing its related morbidity.

Age estimation using third molar teeth: A study on southern Saudi population.

OBJECTIVE: To estimate the age of an individual between 13 and 23 years, using Demirjian method in Saudi male patients in the southern region of the Kingdom of Saudi Arabia. MATERIALS AND METHODS: A total of 360 male patient's digital panoramic radiographs were used to evaluate the morphology of mandibular 3rd molar teeth roots according to the Demirjian method. Using descriptive statistical method, age was calculated. RESULTS: Result showed a strong relation of age with stages of root development of 3rd molar teeth. The standard deviation of mean of root development stages is 1.47 years of age. CONCLUSION: This study suggests that age can be predicted with a statistical significant result for ages between 13 and 23. Further studies with large population are needed for better statistical results and for female age assessment.
