Odontogenic myxoma represents an uncommon benign neoplasm comprising of 3–6% of all odontogenic tumors. This article presents a rare case of odontogenic myxoma occurring in the maxilla of a 7-year-old male patient with a brief review of the pathogenesis, clinical, radiological, histopathological, ultrastructural and immunohistochemical characteristics of odontogenic myxoma.

Palatal rugae are irregular, asymmetric ridges of the mucous membrane extending laterally from the incisive papilla and the anterior part of the palatal raphe. The uniqueness and the overall stability of palatal rugae suggest their use for forensic identification.Objective:The purpose of this study was to compare the palatal rugae patterns in 2 different populations in India (Madhya Pradesh and Kerala), and furthermore, to assess the predominant pattern if any in the selected groups.Materials and Methods:60 maxillary study models (30 from each group) were examined in the age group ranging from 17 to 23 years. Palatal rugae pattern were examined in both the sexes on right and left sides of the palate for the total number (quantitative), length, shape, and predominant direction (qualitative).Results:After analyzing the rugae patterns in both the groups and between the 2 sides of the palate, the wavy pattern was found to be predominant followed by curved, straight, unification, circular, and nonspecific in decreasing order in the overall population.Conclusion:Straight rugae pattern on the right side of the palate in the male subjects was found to be significantly predominant in the MP population, whereas wavy shape was predominant in Keralites; however, rugae patterns on the right side of the palate in female subjects exhibited no significant difference.

Background:Chlorhexidine gluconate mouthwash has earned eponym of gold standard to treat and/or prevent periodontal disease. However, it has been reported to have local side-effects on long-term use. To explore a herbal alternative, the present study was carried out with an aim to compare the anti-plaque efficacy of a herbal mouthwash with 0.2% chlorhexidine gluconate mouthwash and normal saline.Materials and Methods:It was an examiner-blinded, parallel designed clinical trial, in which 90 pre-clinical dental students with gingival index (GI) ≤1 were enrolled. To begin with, GI and plaque index (PI) were recorded. Then, baseline plaque scores were brought to zero by professionally cleaning the teeth with scaling and polishing. After that, randomized 3 groups were made (of 30 subjects each - after excluding the drop-outs) who were refrained from regular mechanical oral hygiene measures. Subjects were asked to swish with respective mouthwash (0.2% chlorhexidine gluconate mouthwash, herbal mouthwash, or normal saline) as per therapeutic dose for 4 days. Then, GI and PI scores were re-evaluated on 5th day by the same investigator, and the differences were compared statistically by ANOVA and Student's ‘t’-test.Results and Observations:Least post-rinsing GI and PI scores were demonstrated with 0.2% chlorhexidine gluconate mouthwash, followed by herbal mouthwash and highest scores with normal saline. The difference of post-rinsing PI scores between the chlorhexidine and herbal mouthwash groups was statistically non-significant, whereas this difference was significant between chlorhexidine and saline groups, and the difference between herbal and saline groups was non-significant. It was concluded that 0.2% chlorhexidine gluconate mouthwash remains the best anti-plaque agent. However, when socio-economic factor and/or side-effects of chlorhexidine need consideration, presently tested herbal mouthwash may be considered as a good alternative.

SummaryMyiasis is a general term for infection by fly larvae feeding on the host's necrotic or living tissue. Although infestation by fly larvae is much more prevalent in animals, it is a relatively frequent in occurrence. Oral myiasis is a rare pathology in humans and is associated with poor oral hygiene. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threatening haemorrhage. The treatment is a mechanical removal of the maggots one by one; however, a systemic treatment with macrolide antibiotics, have been recently used for treatment. We present a case report of a 70-year-old man indigent, alcoholdependent with an extensive necrotic wound in mandible and fetid odour. The prevention of human myiasis is by education, but unfortunately in the developing countries some people live in low social condition, predisposing the occurrence of the infestation. BACKGROUND
