RESUMO
The palatogingival groove is a developmental anomaly on the palatal surface of the maxillary anterior teeth. The shallow groove, often less than 1 mm, is challenging to diagnose, particularly in radiographic examinations. Such grooves are mistaken for root fractures. In this case study, we explore the prevalence, types, radiological appearances, and treatment options of type I shallow palatogingival grooves encountered in cone beam computed tomography.
RESUMO
Condylar hyperplasia (CH) of the mandible is a rare developmental disorder that results in enlargement of the condyle. It is predominant in females, mostly unilateral and self-limiting. This report presents a case of a 35-year-old female patient with unilateral condylar hyperplasia with an increase in vertical height of mandibular ramus of the affected side. After initial radiographic evaluation, the asymmetry index using a panoramic radiograph was determined and also analyzed using cone-beam computed tomography (CBCT). Condylar dimensions in all the planes were measured for both sides using CBCT. This case report emphasizes the importance of CBCT and its role in the diagnosis and assessment of mandibular condylar hyperplasia.
RESUMO
CONTEXT: Tooth plays a pivotal role in the identification of a person when all other remains are ruined by natural or unnatural causes. Dental evidence can contribute to age estimation in forensic dentistry. Estimating the age of an individual with the help of a tooth for identification proves beneficial. Alternating light and dark bands seen on the cementum have been shown to be proportionate to the age of the patient in number. This was done to evaluate the cementum annulation in age determination. AIMS: This study aimed to determine the age of an individual using tooth cementum annulation. MATERIALS AND METHODS: In this study, twenty extracted teeth were collected and all the clinical details of the patient such as age, sex, and chief complaint were recorded. The collected teeth was preserved in formalin overnight and then washed under tap water before they were sectioned. The area selected for counting was observed under 10 × objective of light microscope, and photomicrographs were taken for the counting of the lines. At the time of analysis, the age of the patient was not disclosed to the observer. STATISTICAL ANALYSIS USED: Student's t-test was used for statistical analysis. RESULTS: This study showed the correlation between the actual age of the individual and the estimated age using tooth cementum annulation method and showed significant statistical value. CONCLUSION: Incremental lines found in cementum can be used for age estimation in forensic dentistry.
RESUMO
Ellis-Van Creveld syndrome or chondroectodermal dysplasia is a rare autosomal recessive disorder presenting several skeletal manifestations and congenital heart malformations. Ellis-Van Creveld syndrome comprises of a tetrad of clinical manifestations of chondrodysplasia, polydactyly, ectodermal dysplasia, and cardiac defects. Here, we are presenting a very rare case of Ellis-Van Creveld syndrome in siblings.
RESUMO
AIM AND OBJECTIVE: Some occupational exposures are associated with oral changes in both hard and soft tissues. Presence of oral lesions can interfere with speech, swallowing, and general health of a patient. The present cross-sectional study was conducted to evaluate the oral health status of battery factory workers in Chennai city. MATERIALS AND METHODS: A total of 600 subjects were selected in battery factory out of 3500 workers using statistical sample selection formula 4pq/l(2) and divided into study and control groups based on acid exposure. The data were recorded on a modified World Health Organization 1997 pro forma. The data were evaluated using Chi-square test and Mann-Whitney U-test. MATERIALS AND METHODS: A total of 600 subjects were selected in battery factory out of 3500 workers using statistical sample selection formula 4pq/l(2) and divided into study and control groups based on acid exposure. The data were recorded on a modified World Health Organization 1997 pro forma. The data were evaluated using Chi-square test and Mann-Whitney U-test. RESULTS: Oral symptoms such as disturbed taste, dry mouth, oral ulcers, and foul breath were statistically significant between the groups (<0.001). Dental erosion was statistically significant with the duration of working years. Dental erosion was significant among study group compared to control (0.001). CONCLUSION: The present study showed that selected samples had various oral conditions due to exposure to acids from battery. It was observed that oral health problems were directly related to the duration of acid exposure in the study group. Implementing exhaust ventilation and monitoring the devices help in reducing the acid exposure. Implementation of oral hygiene education and nutritional supplementation helps in improving their oral health.
