Materials and Methods: Forty extracted human single-rooted deciduous teeth were prepared to 40 K file. Prepared teeth were randomly divided into two groups (n = 8); 5.25% NaOCl (group 1) and QMix TM (group 2). Following final irrigation with tested irrigants, the decoronated teeth were split into two halves longitudinally and evaluated and assessed for the amount smear layer present under a scanning electron microscope (SEM). The SEM images were analyzed for the amount of smear layer present using a score system criteria by Rome et al. Data were analyzed using the Fischer exact test. Results: Intergroup comparison of groups 1 and 2 showed statistically significant differences in the coronal (P = 0.001) and middle thirds (P = 0.032); however, in the apical third the canal surfaces were cleaner in samples from group 2 (P = 0.046) as compared to group 1.

K8 and K19 are known to be chemically homologous during the formation of tooth structures. This feature is rather unique and is expressed across the milieu of odontogenic tissues in the physiological and pathological states. The present study was designed to evaluate the expressions of K8 and K19 in odontogenic lesions immunohistochemically and to test the hypothesis that they can be used to identify the odontogenic epithelium. Study Design: K8 and K19 were assessed in 60 cases of odontogenic lesions retrieved from the archival files, which included ameloblastoma (18), ameloblastic carcinoma (2), adenomatoid odontogenic tumor (AOT) (9), squamous odontogenic tumor (SOT) (1), odontogenic keratocyst (OKC) (10), dentigerous cyst (10), and radicular cyst (10), including two cases of normal gingiva and follicular tissue. Results: K8 was expressed in 53/60 (88.3%) and K19 in 56/60 (93.3%) odontogenic lesions. The labeling for K19 was found to be more intense compared to that for K8. Further, K8 and K19 were found to be positive in all the gingival and follicular tissues. Conclusions: Positive expressions of K8 and K19 in all the odontogenic lesions studied suggest that these can be used as definitive markers for identifying the odontogenic epithelium. However, the intense and consistent expression of K19 suggests that this CK is extremely sensitive in identifying the odontogenic epithelium.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129679797","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}

Because of their impaired vision, blind children are at greater risk for anterior tooth trauma. Aim: The aim of the study was to determine the prevalence of anterior tooth fracture among visually impaired individuals and to know the probable cause and risk factors of anterior teeth trauma. Settings and Designs: This cross-sectional study was conducted among visually impaired children in two special needs schools at Dhalli, district Shimla and at Sunder Nagar, district Mandi, in Himachal Pradesh. Materials and Methods: This study was carried out on a conveniently sampled group of 99 blind individuals (64 males and 35 females) aged 9-22 years in December 2011. The study was carried out by a single examiner according to World Health Organization (WHO) criteria and using the WHO classification for teeth fracture. Statistical Analysis: Statistical analysis was carried out using SPSS version 15 (SPSS Inc., Chicago, IL, USA). Chi-square test was used for comparison. P < 0.05 and P < 0.01 were considered as statistically significant and highly significant respectively. Results: An overall prevalence of 33.3% of traumatic injuries to anterior teeth was found in the study population. Females experienced significantly more trauma than males and indoor fall injuries were the most common cause. The permanent maxillary central incisors were most commonly injured, involving enamel and dentin. Increased overjet and inadequate lip coverage were significantly associated with the occurrence of trauma. Conclusion: The present study revealed a higher prevalence of traumatic injuries to anterior teeth among blind individuals. Hence, there is a distinct need for strengthening the provision of oral health-care facilities to these  disabled children, such as preventive orthodontic treatment and the use of mouthguards.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128093703","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}

Objectives: To evaluate the frequency of isolation and quantitative differences in candidal carriage and species recognition in healthy controls and OSCC patients. Materials and Methods: The sample for the present study comprised a total of 30 OSCC patients and 30 healthy controls. The present study was conducted in the Department of Oral Pathology in collaboration with the Departments of Biochemistry and Microbiology at SDM College of Medical and Dental Sciences, Sattur, Dharwad. The subjects included in this study were selected from the Craniofacial Unit, Oral Medicine SDM College of Dental Sciences, Dharwad and Cancer Hospital, Navanagar, Hubli and were categorized into Group I, comprising healthy volunteers and patients with good oral hygiene and no systemic disorders (healthy controls; 30), and Group II, comprising clinically known OSCC patients who were confirmed histopathologically (OSCC; 30) with Well Differentiated-22, Moderate Differentiated-7, Poorly Differentiated-1. The subjects included in this study were randomly selected from among the patients who were referred to the Department of Oral Pathology for various investigations. The consent for this study was obtained from them after the disclosure of necessary information. The complete history was taken from each subject. The details of each subject′s habits, especially of the use of tobacco and smoking, were specifically sought. In the present study, the OSCC cases have been graded histopathologically based on Broder′s system of classification. Unstimulated whole saliva was collected from both groups and inoculated onto the Sabouraud dextrose agar (SDA) plate. The germ tube test, sugar assimilation test, and cornmeal agar morphology were used for the identification of species of Candida. Results: Candida albicans was the predominant species to be isolated in OSCC patients. Other common Candida species isolated from the same group were Candida guilliermondii, Candida krusei, C. tropicalis, and Candida kefyr. Interpretation and Conclusion: The findings of the present study suggest that the elevated candidal carriage, especially if based on the colony-forming units (CFUs) of C. albicans in OSCC patients, could be a future tumor marker, and this aspect of the study has to be addressed and evaluated extensively. Salivary parameters offer the scope for detailed future research on their applications in the screening, diagnosis, and management of cancer.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116423554","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}

The oral health of patients with head and neck cancer undergoing radiotherapy or those who have completed such treatment deteriorates as oral tissues, including the periodontium, are adversely affected. Vascular changes, in particular, predispose the periodontium for degeneration and also reduce the potential of tissues to regenerate following periodontal surgery. Since periodontal surgical procedures or extraction of teeth carries the risk of osteoradionecrosis (ORN) in such cases, a conservative approach with nonsurgical measures is preferred for the treatment of periodontal diseases. This report highlights a case of treatment of localized chronic periodontitis around endodontically treated teeth in a patient with history of radiotherapy for the treatment of oral cancer. In addition to mechanical debridement, PDT was used to disinfect the moderately deep periodontal pockets, resulting in significant improvement. No complication was observed after therapy and good periodontal health has been maintained for the last 18 months.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124398664","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}

In this case report, we discuss marsupialization as a more conservative initial treatment modality for a large AOT with good cosmetic outcomes. The case of a 13-year-old boy with an unusually large maxillary AOT is presented. This large follicular variant of AOT was successfully managed by marsupialization with a 1-year follow-up. Marsupialization can be a preferred initial surgical approach to facilitate regression of the bony swelling and to promote eruption of the impacted tooth with or without orthodontic treatment.

Aim: To investigate the reasons for primary teeth extraction and the tooth type most frequently extracted in children up to 14 years of age. Design: In this retrospective cross-sectional study, 337 boys (50.2%) and 334 girls (48.8%) were evaluated. All children who had their primary teeth extracted during the survey period were included. Descriptive statistics were used, including the patient′s age, gender, number of teeth, tooth type extracted, and reasons for extraction. Results: A total of 867 primary teeth were extracted from 671 children. The majority of dental extractions (62.2%) was performed between the ages 6-10 years. Tooth loss was slightly more in boys than in girls (P = 0.77). Dental caries was the most frequent (58.6%) cause of tooth mortality. Extractions due to mobility of teeth, overretention, orthodontic purposes, trauma and failed endodontic treatment were 16.9%, 13%, 7.3%, 3%, and 1.2%, respectively. There were significantly more (P < 0.0001) posterior teeth (67.1%) extractions than anterior teeth (32.9%). The arch distribution of extracted primary teeth was 46.7% in the maxilla and 53.3% in the mandible (P = 0.000).
