A Unique Case of Plunging Dermoid Cyst in an Elderly Male: A Case Report.

Dermoid cysts are the least commonly occurring developmental cysts in the oral and maxillofacial region. They may be congenital or acquired and are seen as asymptomatic swellings that are slow and progressive. It is very difficult to differentiate plunging ranulas from plunging dermoid cysts as both of them have very similar clinical features. However, since both entities have different treatment strategies, it is important to differentiate one from the other. A 57-year-old male patient reported to the Department of Oral Medicine and Radiology with a large swelling in the submental region. To the best of our knowledge, the present case report is the first one showing such an extensive lesion of plunging dermoid cyst mimicking plunging ranula in an elderly male patient. The report mainly focuses on the diagnostic challenges faced to reach the final diagnosis.

Determination of sexual dimorphism of maxillary sinus using cone-beam computed tomography in a rural population of western Maharashtra - A retrospective, cross-sectional study.

Context: Radiography is used in forensics for the identification of humans, especially in cases where the body is decomposed, fragmented, or burned. In the skull bones, the zygomatic bone and maxilla including the maxillary sinus tend to remain intact even if the other bones are badly disfigured. Hence, the maxillary sinus has been considered by several authors for sex identification. The cone-beam computed tomography (CBCT) is a non-invasive, recently developed technology that has seen an exponential rise in the use for visualizing dental anatomy and pathologies. The present study chose the available CBCT records of patients who show maxillary sinus and used them for determining sexual dimorphism related to the maxillary sinus. Aims: To measure the maxillary sinuses using CBCT and determine the efficacy of these measurements for sex identification. Settings and Design: Observational, cross-sectional, retrospective study. Methods and Material: A total of 60 CBCT scans (30 males, 30 females) were selected from a rural setup, and the height, length, and width of the maxillary sinus with the highest dimension for each variable were measured and recorded. Statistical Analysis: The data were analyzed by using the paired t-test. The discriminant equations were derived for both the right and left maxillary sinus. Results: Statistically significant differences were observed between the males and females for height (right and left) and length (left) of the maxillary sinus. The accuracy rate for sex identification in the present study was found to be 71.3%. Conclusion: Maxillary sinus height can be used as a reliable radiographic marker in forensic odontology for sex identification.

Solitary Bone Cyst of Posterior Maxilla: A Rare Presentation.

Solitary bone cyst (SBC) is an uncommon, nonneoplastic osseous lesion that mainly affects metaphysis of long bones and rarely presents in jaws. Due to the lack of true epithelial lining, it is considered as a pseudocyst. It is generally asymptomatic and often discovered incidentally during routine radiographic examination as well-defined unilocular or multilocular radiolucent lesion in the posterior mandible mainly in the first two decades of life. Here, we report a very rare case of a 15-year-old female patient having a lesion in the posterior maxilla with clinical, radiological, and histopathological presentations of SBC.

An institutional survey for knowledge-based and self-awareness assessment in temporomandibular joint disorders among dental students.

CONTEXT: Temporomandibular joint disorders (TMDs) have been recognized as one of the most common causes of nondental orofacial pain. Various studies have been reported in literature regarding the relationship between prevalence of signs and symptoms of TMDs and gender, suggestive of female predilection; however, none of the studies have yet been reported to suggest the relationship between knowledge about temporomandibular joint (TMJ) and TMDs and self-awareness of its signs and symptoms. AIM: To find a relationship between the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms. SETTINGS AND DESIGN: This study was designed as an institutional survey. The study sample comprised 491 undergraduate and postgraduate (PG) students, consisting of 90 males and 401 females with age ranging between 18 and 32 years. SUBJECTS AND METHODS: Two sets of questionnaire were distributed among the students. STATISTICAL ANALYSIS USED: Statistical analysis was performed with the help of Epi Info (TM) 3.5.3, descriptive statistical analysis, test of proportion, Chi-square test, one-way analysis of variance, Tukey's test, and knowledge index. RESULTS: It was observed that there was a gradual increase in the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms from the 1st year to PG students. CONCLUSIONS: A direct relationship exists between the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms.

A rare presentation of hybrid odontogenic tumor involving calcifying cystic odontogenic tumor and plexiform ameloblastoma.

A hybrid odontogenic tumor comprising two distinct lesions is extremely rare. We presented a hybrid odontogenic tumor composed of a calcifying cystic odontogenic tumor (CCOT) and a plexiform ameloblastoma. This tumor was observed in the anterior area of the mandible of a 17-year-old Indian male. Masses of ghost epithelial cells with the characteristics of CCOT were seen in the lining of the cyst. The odontogenic epithelia with the features of plexiform ameloblastoma were also observed.

A study to evaluate mobility of teeth during menstrual cycle using Periotest.

BACKGROUND AND OBJECTIVE: Over a century, an increased prevalence of gingival disease associated with increasing plasma sex steroid hormone levels has been reported. These situations present unique challenges to the oral health care professional. It is believed that hormonal fluctuations such as those associated with pregnancy, menstruation, and use of hormonal contraceptives lead to an increase in tooth mobility. However, this effect of female sex hormones on periodontal ligament and tooth supporting alveolar bone has rarely been investigated. So this study was undertaken to understand the effect on tooth mobility because of hormonal changes during the menstrual cycle. MATERIALS AND METHODS: The mobility of index teeth 16, 13, 21, 23, 24, 36, 33, 41, 43, and 44 was measured with Periotest in 50 females at menstruation, ovulation, and premenstruation time points. Simplified oral hygiene index, plaque index, gingival index, and probing depth were also evaluated during the different phases of menstrual cycle for each subject participating in the study. STATISTICAL ANALYSIS: The results of the study were subjected to statistical analysis. Data analysis was done by applying Z test for comparing difference between two sample means. RESULT: The stages of menstrual cycle had no significant influence on the Periotest value. Despite no significant change in plaque levels, GI was significantly higher during ovulation and premenstruation time points. CONCLUSION: No change in tooth mobility was seen during the phases of the menstrual cycle. However, an exaggerated gingival response was seen during ovulation and premenstruation time when the entire menstrual cycle was observed.
