Background: Hepcidin is a 25 amino acid peptide expressed in the liver. Discovered as late as 2002, hepcidin is a master regulator of iron metabolism and is sensitive to inflammation. Chronic periodontitis, being an inflammatory condition, affects levels of hepcidin. There exists a linear correlation between chronic generalized periodontitis (CGP) and cardiovascular disease (CVD). Objective: To assess and compare serum hepcidin between Group I (Control Group—CGP without CVD) and Group II (Case Group—CGP with CVD). Methods: Blood samples of 20 patients from Group I and 20 patients from Group II were collected and centrifuged to separate serum samples. ELISA kit was used for the estimation of serum hepcidin levels. The statistical analysis was done using G-Power version 3.1 software. Results: The serum hepcidin levels in Group I and Group II were found to be insignificant (P = 0.742679, P < .05). Conclusion: Serum hepcidin levels were higher in Group I when compared with Group II. We can conclude that there is an increase in the hepcidin levels due to inflammatory conditions. However, using hepcidin as a biomarker in CVD needs further examination using a larger sample size with long-term observations.
背景：肝素是一种在肝脏中表达的 25 个氨基酸的多肽。肝磷脂酶是铁代谢的主要调节因子，对炎症很敏感。慢性牙周炎是一种炎症，会影响肝磷脂酶的水平。慢性泛发性牙周炎（CGP）与心血管疾病（CVD）之间存在线性相关。研究目的评估并比较 I 组（对照组--无心血管疾病的 CGP）和 II 组（病例组--有心血管疾病的 CGP）的血清降血脂素。方法采集 I 组和 II 组 20 名患者的血样，离心分离血清样本。使用 ELISA 试剂盒测定血清中的血红素水平。使用 G-Power 3.1 版软件进行统计分析。结果发现第一组和第二组的血清降血脂素水平不显著（P = 0.742679，P < .05）。结论与第二组相比，第一组的血清降血脂素水平更高。我们可以得出结论，炎症会导致血红素水平升高。不过，将血红素作为心血管疾病的生物标志物还需要通过更大样本量的长期观察进行进一步研究。

Background: Oral submucous fibrosis (OSMF) is an insidious chronic disease involving any part of the oral cavity. As ultrasonography (USG) facilitates imaging of a wider area, it can be a valuable tool to determine the severity of this disease. Objective: With this background, this study was undertaken to assess oral mucosal changes by ultrasonography and color Doppler in OSMF. Materials and Methods: The sample size included 40 subjects between 20 and 60 years inclusive of either gender, divided into group 1 (controls) and groups II, III, and IV (OSMF cases). The submucosal thickness of buccal mucosa and upper and lower labial mucosa was measured by USG followed by analysis of submucosal vascularity by color Doppler. The data were subjected to statistical analysis. Results: It was found that all the subjects had normal submucous thickness and normal vascularity in group 1 (controls). In group II to group III to group IV cases, there was an increase in submucosal thickness and a decrease in submucosal vascularity as the stage of OSMF progressed and the results were statistically significant. Conclusion: USG and color Doppler were able to demonstrate an increase in the thickness of the submucosal layer and a decrease in submucosal vascularity with the progression of OSMF. Hence, USG assessment of OSMF can supplement with other modalities for monitoring disease progression.

In the nonsurgical therapy of periodontal disease, scaling and root planing (SRP) is the gold standard. Bacterial recolonization occurs from the residual subgingival plaque or from other oral contaminants. To avoid bacterial recolonization, regular periodontal care is essential, as well as the inclusion of coadjutants and active debridement, including such antibiotic therapy and photodynamic therapy. Therefore, the aim of this systematic review and meta-analysis is to evaluate periodontal tissue changes after photodynamic therapy in aggressive periodontitis. An electronic search was conducted on PubMed/ MEDLINE, GOOGLE SCHOLAR, and HAND SEARCH of a reference list of archived articles published from January 2015 to August 2018. After thorough scrutiny, five studies assessing clinical attachment level (CAL) and probing pocket depth (PPD) were considered for the meta-analysis. Using fixed and random effect models, the standardized mean differences (SMDs) were calculated. Results of the fixed and random-effect models had slightly distinct estimates of SMD of CAL, both models resulted in positive and significant treatment effects. The fixed effect was slightly different and positive for PPD (SMD = 0.843, 95 percent CI = 0.510 to 1.176, P = 0.001, significant), while random effects were somewhat different and positive for PPD (SMD = 1.227, 95 percent CI = -0.129 to 2.582, P = 0.076, not significant). Because of heterogeneity, one model indicated substantial treatment effects for PPD, whereas another model showed non-significant treatment effects. Hence, the results concluded the beneficial effects of photodynamic therapy in aggressive periodontitis.

Background: Hyperglycemia and other risk factors lead to the formation of plaques in the neck area of the carotid artery. Carotid atheroma plaque may predispose or increase risk of cerebrovascular accident. Panoramic radiographs can pick up mere calcified plaque and early referral to a physician would prevent long-term complications. Materials and Methods: The electronic and hand search of studies published until October 2022, yielded a total of 17 articles, out of which 4 studies met the inclusion criteria. All studies examined the prevalence of carotid atheroma in panoramic images of patients with type 2 diabetes. The risk of bias was assessed by the Newcastle-Ottawa scale. Results: This systematic review search yielded 168 publications from various databases. After reading the full text, four articles were selected and met the selection criteria. All four studies showed the level of evidence IV which was assessed using Agency for Health Research and Quality (AHRO) guidelines. Conclusion: The prevalence of carotid atherosclerotic plaques is higher in diabetic patients compared to non-diabetic patients. Literature-based evidence suggests that carotid atheroma can be detected on panoramic images and the patients can be referred to a doctor for further examination and necessary treatment.

Background: Communication skills significantly contribute to good clinical practice. A systematic approach to delivering bad news could avoid unfavorable workplace circumstances. SPIKES protocol has been incorporated into clinical practice in many countries to deliver bad news systematically to build a better doctor–patient relationship. Objectives: To assess post-graduate residents' awareness and practice of SPIKES protocol and to determine the need for training/education for delivering bad news. Methods: A cross-sectional study among 96 post-graduates from various medical and dental clinical departments was done using a self-directed questionnaire consisting of four sections (i.e. socio-demographic data, awareness and adherence, practice, and need for training/education). The questionnaire was circulated through online platforms, and responses were tabulated. Results: About 55% of the participants were aware of the SPIKES protocol. About 90% felt that the protocol was simple, easy, and practical. 92% felt that adequate training is required for delivering bad news. Also, 90% of the participants expressed a willingness to attend training sessions to improve their communication skills. Conclusion: Only half of the study population was aware of the SPIKES protocol; among them, a fair adherence to the protocol was noted.

Background: Radiographical examination of temporomandibular joint (TMJ) showing changes in the shape of the condyle. Clinicians should have anatomical knowledge to assess the morphology of the condyle. Early detection of TMJ prevents the future possibility of osseous deformities. Objectives: To assess the prevalence of morphological variations in the condyles of dentate patients on digital panoramic radiographs. Methods: A total of 2364 digital panoramic radiographs were retrospectively selected from the previous patient's record that visited the Department and were observed by two radiologists for formulation of operational definitions. The OPG was evaluated for the subcondylar cysts, osteophytes, erosions, knife edges, and flattening of condyles. Morphological trends in condyles were evaluated. The obtained data were analyzed using descriptive statistics. Results: 68.73% of cases showed positive condylar changes, among which 31.13% revealed osteophytes, 27.13% flattening of condyles, 26.46% erosions, knife edges, and subcondylar cysts were 8.30%, and 6.95%, respectively, and the relationship between the type of condyles and the age groups were found to be statistically significant (P value: 0.05). Conclusions: Osteophytes were found to be the most predominant feature than other condylar morphological changes so preventive measures to be taken to stop further progression of the disease.

Background: The posterior superior alveolar artery (PSAA) is commonly encountered during various surgical procedures such as sinus lift, osteotomy, and Le Fort I fractures. Objective: This study was undertaken to evaluate the anatomical relationship of PSAA with the alveolar crest using cone-beam computed tomography (CBCT). Methods: This retrospective, analytical, comparative study was conducted on 192 CBCT scans (=384 PSAA notches) of dentulous patients above the age of 20 years. The position, diameter, and distance of the artery to the alveolar crest in the first molar region were evaluated bilaterally, in different age groups and among both genders. Results: In our study, the position and dimension of the notch of the PSAA were statistically significant with respect to age. The distance of the artery to the alveolar crest was statistically significant with respect to age and gender. No side differences were seen. Conclusion: The distance of the PSAA to the alveolar crest in the first molar region was approximately 14.62 mm in the Indian population. Hence, surgical procedures involving this artery should be conducted at a distance of <14 mm to avoid hemorrhage. CBCT can be used to evaluate the position and path of the PSAA accurately.
背景：牙槽后上动脉 (PSAA) 常见于各种外科手术，如上颌窦提升术、截骨术和 Le Fort I 型骨折。研究目的本研究使用锥束计算机断层扫描（CBCT）评估牙槽嵴后上动脉（PSAA）与牙槽嵴的解剖关系。方法这项回顾性、分析性和比较性研究对 20 岁以上无牙患者的 192 张 CBCT 扫描（=384 个 PSAA 缺口）进行了分析。评估了不同年龄组和不同性别患者第一磨牙区双侧动脉的位置、直径和到牙槽嵴的距离。结果：在我们的研究中，PSAA 缺口的位置和尺寸与年龄有显著的统计学关系。动脉到牙槽嵴的距离与年龄和性别有统计学意义。没有发现侧面差异。结论在印度人群中，第一磨牙区的 PSAA 与牙槽嵴的距离约为 14.62 毫米。因此，涉及该动脉的手术应在距离小于 14 毫米时进行，以避免出血。CBCT 可用于准确评估 PSAA 的位置和路径。

Background: Gender determination is a standard practice in forensic science as it forms the prime phase in the reconstruction of a post-mortem profile. The maxillary sinus (MS) is the largest among the paranasal sinuses with characteristic morphological features. Cone-beam computed tomography (CBCT) imaging, widely popular now for its imaging accuracy, may be considered for recording morphometric measurements of maxillary sinuses for gender determination. Aim: To compare and analyze the applicability and accuracy of measurement parameters (length, width, height, and volume) for the evaluation of sexual dimorphism of MS. Methods: CBCT scans were used to measure the height, length, width, and volume of MS in 60 patients to identify an individual's gender for forensic evaluation. The parameters were analyzed using discriminant function analysis and independent t test to compare these values in both genders. Results: Combined measurements of all study parameters were analyzed, and an overall accuracy rate of 61.67% was observed. Conclusion: Morphometric measurement parameters of MS attained using CBCT seem to have a moderately good prediction value.
背景：性别鉴定是法医学的标准做法，因为它是重建尸体轮廓的首要阶段。上颌窦（MS）是副鼻窦中最大的一个，具有独特的形态特征。锥形束计算机断层扫描（CBCT）成像因其成像准确性而广受欢迎，可考虑用于记录上颌窦的形态测量，以确定性别。目的：比较和分析测量参数（长度、宽度、高度和体积）在评估 MS 性双态性方面的适用性和准确性。方法：使用 CBCT 扫描仪测量多发性硬化症患者的鼻窦：使用 CBCT 扫描测量 60 名患者多发性硬化症的高度、长度、宽度和体积，以确定个人的性别，用于法医评估。使用判别函数分析和独立 t 检验对这些参数进行分析，以比较男女性别的这些数值。结果：分析了所有研究参数的综合测量值，观察到总体准确率为 61.67%。结论使用 CBCT 获得的 MS 形态测量参数似乎具有较好的预测价值。

The maxillary sinus (MS) is the largest among the paranasal sinuses with characteristic morphological features. Cone-beam computed tomography (CBCT) imaging, widely popular now for its imaging accuracy, may be considered for recording morphometric measurements of maxillary sinuses for gender determination. Aim: To compare and analyze the applicability and accuracy of measurement parameters (length, width, height, and volume) for the evaluation of sexual dimorphism of MS. Methods: CBCT scans were used to measure the height, length, width, and volume of MS in 60 patients to identify an individual's gender for forensic evaluation. The parameters were analyzed using discriminant function analysis and independent t test to compare these values in both genders. Results: Combined measurements of all study parameters were analyzed, and an overall accuracy rate of 61.67% was observed. Conclusion: Morphometric measurement parameters of MS attained using CBCT seem to have a moderately good prediction value.","PeriodicalId":31366,"journal":{"name":"Journal of Indian Academy of Oral Medicine and Radiology","volume":"8 1","pages":"412 - 416"},"PeriodicalIF":0.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139364645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Intraosseous anastomosis (IA) found in the lateral wall of the maxillary sinus (MS) is a potential site for bleeding during surgeries. Objectives: To investigate the position of IA in male and female, and dentulous and edentulous patients in relation to the MS floor and volume of MS. Methods: The study is comprised of 60 cone-beam computed tomography (CBCT) scans of the maxilla. Distances from the floor of the MS to the IA canal and from the MS floor to the alveolar crest were measured. The canals are classified into three types. The volume of the MS and its relation to the IA was assessed. Results: Statistical difference was noted in the position of the IA in relation to second premolar and in dentulous and edentulous patients. Intraosseous was the most common type of canal. The difference in volume did not affect the position of the canal. Conclusions: IA was closer to the floor of the MS in the second premolar region in females. Knowing the type and position of the canal helps prevent complications during surgery.
背景：上颌窦（MS）侧壁的骨内吻合口（IA）是手术中潜在的出血部位。研究目的研究男性和女性、有牙和无牙患者的 IA 位置与上颌窦底和上颌窦容积的关系。方法：研究包括 60 次上颌骨锥形束计算机断层扫描 (CBCT) 扫描。测量了从MS底部到IA管的距离，以及从MS底部到牙槽嵴的距离。牙槽骨分为三种类型。对MS的体积及其与IA的关系进行了评估。结果：与第二前磨牙相比，无牙和无牙患者的 IA 位置存在统计学差异。骨内是最常见的牙管类型。体积的差异并不影响牙管的位置。结论：在女性的第二前磨牙区，IA更靠近MS的底面。了解牙槽骨的类型和位置有助于预防手术并发症。

Objective: The present study aims to evaluate the number of micronuclei (MN) in potentially malignant disorders (PMDs) and oral cancer and correlates them with the control group. Materials and Methods: Subjects included in the study were equally divided into four groups. Exfoliated cells were then obtained from the buccal mucosa using cytological brush. Smears were stained using rapid Pap stain. The smears were observed using a light microscope, and MN was counted out of 10 high-power fields and scored according to PE Tolbert (1992) criteria. Results: The mean MN count was found to be 0.23, 2.10, 3.03, and 3.57 in groups I, II, III, and IV, respectively. The overall intergroup comparison between the four groups was found to be statistically significant with a P value less than 0.05. Conclusion: This study gives a fair assessment that MN assay in exfoliated cells of oral epithelium can be a conducive biomarker while screening for PMDs of the oral cavity in doubtful lesions that are primarily misdiagnosed clinically.
