Preoperative Anatomic Evaluation of the Relationship Between Inferior Alveolar Nerve Canal and Impacted Mandibular Third Molar in a Population of Bhubaneswar, Odisha, Using CBCT: A Hospital-Based Study.

PURPOSE: To evaluate the correlation between the position of inferior alveolar nerve canal and the angulation of impacted mandibular third molars using cone beam computed tomography (CBCT) in a hospital-based study in the state of Odisha, India. MATERIALS AND METHODOLOGY: Three hundred cases of impacted third molars in 200 patients (154 males; 46 females) were included in the study, for whom an initial periapical or panoramic radiograph had revealed that the mandibular canal and the lower third molars were in close proximity. A CBCT scan of each patient was carried out to assess how the canal position influenced the class and position of impaction, angulation of impaction and bone contact. RESULTS: Class II position B impactions were found in 78.37% cases where the position of ID canal was approximate to the lingual plate and inferior to third molar (73.75%). The results were statistically significant (p = 0.00). 80% of the ID canals showed bone contact. Of these 73.75% ID canals showed lingual bone contact. Mesioangular impactions were most common in mandible and significantly associated with lingual and inferior positioning of the canal. CONCLUSIONS: The study mostly exhibited patients having mesioangular class II position B third molar impactions of the mandible. The position of the canal has a significant influence on the type of impaction and the bone contact.

Prevalence of oral lesions in tuberculosis: A cross sectional study.

OBJECTIVE: Tuberculosis (Tb) is a fatal infectious disease that primarily affects the pulmonary system and rarely occurs in other body organs including oral cavity. The aim of this study was to report all patients with primary manifestations of oral tuberculosis and to evaluate the clinical characteristics of oral tuberculosis lesions. All these patients were subsequently diagnosed with tuberculosis based on oral histological findings and referred for management and therapy. MATERIALS AND METHODS: Twelve patients with oral lesions from the year 2010 to 2018 were histologically diagnosed as having tuberculosis, who did not give any history of the disease, following surgical biopsy. Clinical symptoms, auxiliary examinations, treatments, and outcomes were recorded and analyzed. RESULTS: Oral TB was found in all 12 patients; 8 males and 4 females, with male to female ratio 8:4. Involved oral sites included the angle of the mandible (one case), right mandibular molar region (two cases), left mandibular molar region (four cases), gingiva (three cases), buccal mucosa (one case), and the tongue (one case). Oral TB patients in this series ranged in the age group of 6-65 years. All the lesions were suggestive of primary tuberculosis. The appearance of the affected mucosa in oral TB was variable. The most common manifestation was ulceration and swelling of the mucosa. CONCLUSION: TB should be considered in patients with oral ulcerations and swellings. A biopsy specimen for histological study, acid-fast stains, and cultures should be obtained for confirmation and differential diagnosis along with other conditions.

Oral Submucous Fibrosis: Correlation of Clinical Grading to Various Habit Factors.

OBJECTIVES: The aim of this study was to correlate the clinical grading of oral submucous fibrosis (OSMF) with various habit factors and to observe the habit factors associated with the severity of OSMF. MATERIALS AND METHODS: This study was carried out in the Department of Oral Medicine and Radiology, Kalinga Institute of Dental Sciences, Bhubaneswar, Odisha, India. Two hundred patients clinically diagnosed with OSMF were included in the study. The observations were tabulated and subjected to statistical analysis using chi-square test and Spearman's rank correlation test. RESULTS: A total of 200 subjects participated in the study of which 182 were males and 18 were females. Forty-eight males and nine females had Grade I OSMF. One hundred nineteen males and eight females had Grade II OSMF. Fifteen males and only one female had Grade III OSMF. On the basis of functional staging, the total participants in stage I, stage II, and stage III were 185, 14, and 1, respectively. The participants having Grade I, Grade II, and Grade III OSMF with functional staging I were 57, 122, and 6, respectively. The participants having Grade II and Grade III OSMF with functional staging II were 5 and 9, respectively. CONCLUSION: It is alarming that nearly half of the total subjects were in the younger age group and were having OSMF. Also, as the age increased, the subjects were found to be more attracted to consuming areca nut derivatives in the form of betel quid with or without tobacco. It is recommended that community-oriented outreach programs on oral health awareness be developed, emphasizing children who represent the upcoming future, to avoid/quit areca nut and its derivatives.

Peripheral Cemento-Ossifying Fibroma withUncommon Clinical Presentation: A Case Report / Fibroma periférico cemento-ossificante con una presentación clínica poco común: Reporte de caso

Abstract Peripheral cemento-ossifying fibroma (PCOF) is a reactive gingival over growth, occurring frequently in the maxillary anterior region of teenage and young females. Peripheral cemento-ossifying fibroma (PCOF) is supposed to be originating from periosteum and/or periodontal ligament. A large number of factors have been implicated in the pathogenesis of PCOF, which includes trauma, local irritation, calculus and hormonal disturbances. The definitive diagnosis of PCOF is based upon its clinical, radiological and histological features. Because of the high recurrence rate (8-20%) of PCOF, a close post-operative follow-up is required. Herewith, we are presenting a case of PCOF in 24-year old female patient at an uncommon location.

Resumen El fibroma cemento-osificante periférico (PCOF, por sus siglas en inglés) es un crecimiento gingival reactivo, que se produce con frecuencia en la región anterior del maxilar en adolescentes y mujeres jóvenes. Se supone que el fibroma cemento-osificante periférico (PCOF) se origina en el periostio y/o el ligamento periodontal. Una gran cantidad de factores han sido implicados en la patogénesis de PCOF, dentro de las que se incluye trauma, irritación local, cálculo y alteraciones hormonales. El diagnóstico definitivo de PCOF se basa en sus características clínicas, radiológicas e histológicas. Debido a la alta tasa de recurrencia (8-20%) , se requiere un seguimiento post-operatorio estricto. Mediante este artículo presentamos un caso de PCOF en una paciente de 24 años de edad y el manejo teraupético.

Angiosarcoma of mandible: An uncommon clinical entity.

Angiosarcoma is a malignant neoplasm of endothelial cells of blood vessels, representing 2% of all sarcomas. The occurrence of angiosarcoma in the oral cavity is a rare. In general management includes resection and wide-field postoperative radiation therapy. The risk of local-regional failure and distant relapse is still a cause of worry. Herewith, a case of angiosarcoma of mandible in a female patient is presented, who presented with small, innocent-looking mass, which became a highly destructive malignant tumor within few days.

Evaluation of ponticulus posticus on digital lateral cephalograms and cone beam computed tomography in patients with migraine and healthy individuals: a comparative study.

OBJECTIVE: The purpose of this study was to investigate the prevalence of ponticulus posticus (PP) in patients with migraine. STUDY DESIGN: The presence and types of PP were investigated in 100 patients with migraine and 100 healthy controls on digital lateral cephalograms and cone beam computed tomography (CBCT) scans. RESULTS: PP was found in 42% of the patients with migraine and in 19% of the healthy controls on digital lateral cephalograms. CBCT scan found PP in 40 patients with migraine and in 18 healthy controls. The agreement between the occurrence of PP seen on digital lateral cephalograms and that seen on CBCT images was "very good" (κ = 0.92). CONCLUSIONS: Significant association was found between PP and migraine. PP is easily visible on lateral cephalograms. For a more accurate diagnosis, CBCT is required. Therefore, radiographic detection of PP must be considered an important task, because this anomaly may be a key indicator of an underlying disease process.
