Objectives: Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. Study Design: A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. Results: 1519 (36.7%) patients had at least one dental anomaly. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other anomalies were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). Conclusion: The most prevalent anomaly in the Indian population was congenitally missing teeth (16.3%), and the second frequent anomaly was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent anomalies, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these anomalies may be low, the early diagnosis is imperative for the patient management and treatment planning. Key words:Dental anomaly, prevalence, panoramic radiography.
Objective: Tongue lesions are a health concern for the dental practitioners and the patients as they constitute a significant proportion of oral mucosal lesions. The aim of the present study was to determine the prevalence of various tongue lesions in the Indian population. Material and methods: 4926 patients attending the Department of Oral Medicine and Radiology were examined for the presence of various tongue lesions during the period from October, 2010 to September, 2012. The age of the patients ranged from 12-80 years with a mean age of 36.51 years. Results: The prevalence of tongue lesions was 12.07%. The most common lesion diagnosed was coated tongue affecting 28.0% of the subjects, followed by geographic tongue (16.4%), fissured tongue (14.9%) and depapillated tongue (11.5%). Males were more frequently affected than females. The most common systemic condition observed in the patients with tongue lesions was anaemia (189), followed by hypertension (47) and diabetes mellitus (38). Conclusion: The high prevalence necessitates adequate awareness of the various tongue lesions in the general population. The dental clinicians should also be knowledgeable about the etiopathogenesis, clinical presentation, diagnosis, and treatment of these lesions. Key words:Tongue lesions, prevalence, Indian population, coated tongue.
Objective: Patients with an oral ulcer may present initially to a general physician or a dental practitioner. Majority of the ulcers are benign and resolve spontaneously but small proportions are malignant. The aim of the present study was to determine the prevalence of recurrent aphthous ulcerations in the Indian population. Material and Methods: 3244 patients attending the Department of Oral Medicine and Radiology during the period from November, 2010 to December, 2012 with various complaints were examined. Of the patients examined 1669 were females and 1575 were males. Results: 705 patients presented with recurrent aphthous ulceration (21.7%). Females (56.3%) were more commonly affected than males (43.7%). Patients in the third and fourth decade were most commonly affected. Stress was the most common factor associated with recurrent aphthous stomatitis (386 patients). 54.5% patients did not take any medications and 72.9% patients opined that the condition needed no dental consultation. Conclusion: The results of the present study indicate that recurrent aphthous ulceration is a common mucosal disorder in the Indian population. The early and proper diagnosis of the ulcers will help the dental practitioner in providing information to the patient regarding awareness and management of the condition. Key words:Recurrent aphthous ulcers, prevalence, Indian population.
Objectives: Taurodontism affects primarily molars and premolars in both the deciduous and permanent dentition. The aim of the study was to assess the prevalence of taurodontism in the North Indian population. Study Design: 4143 patients were studied by analyzing the panoramic radiographs for the presence of taurodontism which is defined as the presence of an apically displaced pulp chamber and the tooth lacks the usual constriction at the cementoenamel junction. The age of the patients ranged from 13 to 38 years with a mean age of 21.8 years. Results: Taurodontism was found in 17 patients with a prevalence of 0.4% of which 0.21% were males and 0.19% females. Taurodonts were significantly more common in the maxilla (65.6%) than in the mandible (34.4%) (p<0.05) and the maxillary second molar (34.4%) was the most commonly involved tooth. According to the morphology hypotaurodonts were most common (75%) but there was no significant difference in males and females (p>0.05). Conclusion: Taurodontism is relatively uncommon in the North Indian population. Further large scale studies need to be carried out to assess its prevalence in the general population. A family history of other anomalies should also be considered for affected patients. Key words:Taurodontism, prevalence, maxillary second molar.
Mucormycosis, caused by saprophytic fungi of the order Mucorales of the class Zygomycetes, is a rare opportunistic fungal infection, which has a rapidly progressive and fulminant course with fatal outcome. These fungi are ubiquitous, found in soil, bread molds, decaying fruits and vegetables. The most common form of mucormycosis is rhinocerebral and is usually seen in uncontrolled diabetes mellitus or in immunocompromised patients. This fungus invades the arteries, leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case of palatal perforation by rhino-maxillary mucormycosis in an immunocompromised patient. The aim of this article is to draw attention to the clinical presentation and pathogenesis of mucormycosis and to emphasize the need for high degree of suspicion in its diagnosis and management.
