Pathology of an eruption of wisdom teeth is importance for a military odontology because the vast majority of the military contingents on age coincides with time of their physiological eruption (16-40 years). In work, on the basis of clinic-radial methods of a research, features of a teething of wisdom at young people of military age are studied and analyzed 3D-tomograms and orthopantomograms of 325 servicemen aged from 18 up to 27 years. During work estimated existence of wisdom teeth on top and lower jaws, extent of their eruption, existence of a retention (or dystopias) and also an adentia or loss of wisdom teeth. It was established that most often eruption of the third molar teeth of jaws at recruits occurs at the age of 23-27 years, at the same time at a series of recruits eruption of the lower wisdom teeth usually is followed by various complications, such as pericoronitis, an acute purulent periostitis of a mandible, a false «acute periodontitis» of the lower second molar tooth that becomes perceptible at mesial shift of a wisdom tooth and dense contact of its coronal part with a distal root of the second molar tooth. The essential value for a full-fledged teething of wisdom has their situation in an alveolar process (part) of a jaw, and further - in dentition. It in many respects defines a clinical picture of the shown eruption complications and also tactics of stomatologic treatment - orthodontic treatment, surgical treatment or their combinations. The infectious and inflammatory complications bound to the complicated their eruption (85,93% of cases) served as the reasons of an exodontia of wisdom. In 14,07% of cases wisdom teeth on both jaws were extracted in a planned order in connection with the forthcoming orthodontic treatment on elimination of dentoalveolar anomalies. Thus, terms and features of a teething of wisdom at recruits need to be considered in clinical practice of a military odontology as their military service can pass in specific living conditions and activity of troops and health service, and at complications of a teething of wisdom the acute stomatologic surgical management, including stationary is in most cases necessary.

The skeleton of Pawon Man’s that lived in Mesolitic era aged 5,660±170 BP - 9,500± 200 BP (Before Present) years before Christ (BC) has been used for forensic odontology research.  However, there has not been any research on dental caries of Pawon Man. The aim of this research was to describe the dental caries in skulls of Pawon Man. The type of the research was descriptive by using purposive sampling. The samples were from four Pawon Man skulls and their teeth. The research was conducted by using clinical examination. All aspects were recorded, collected and presented in tabular form. The result shows that 12.5% of the samples from 32 teeth of skulls of Pawon Man I, III, IV and V had experienced dental caries. Clinical examination shows presence of dental caries in samples of Pawon Man III of  permanent mandibular third molar tooth of region 4(48) in lingual area and buccal lesion of lower left third molar (38). In Pawon IV, lingual lesion of lower left permanent second molar (37) and in lower left permanent third molar (38). All lesions are only in enamel which is code 1 according to ICDAS code. In conclusion, the dental caries in skulls of Pawon Man was low due to their low sugar diets from fruits and sugar-rich plants (fructose sugars). Consumption of hard foods and evidence of presence of animal teeth and mollusks had contributed to the higher percentage of dental attrition compared to dental caries. Keywords: dental caries, clinical, pawon man

Pyogenic granuloma (PG) refers to a common, acquired, benign, and vascular tumor that arises in tissues such as the skin and mucous membranes. However, it is extremely rare for PG to arise from an empty socket after tooth extraction. Herein, we describe a rare case of PG that arose from the empty extraction socket of the second molar adjacent to a dentigerous cyst of the left mandibular wisdom tooth in a 57-year-old man. The patient’s second molar was extracted during the same procedure in which the wisdom tooth and cyst were removed. Subsequently, at 42 days after surgery, an exophytic mass was found in the socket of the second molar. An excisional biopsy was performed, and the histopathological diagnosis was PG. Since the PG recurred 90 days after the surgery, a complete excision with bone curettage was performed. During the 12 months of follow-up, there has been no recurrence observed. In conclusion, as tooth extraction is a routine dental practice, clinicians should be aware that PGs can also develop from an extraction socket.

A 35-year-old woman presented with a progressively increasing swelling over the left side of the upper part of the neck for the past 8 months with no associated pain over the swelling. On examination, a non-tender, firm, well-defined, oval swelling of size 3×2 cm was palpable in the left submandibular region that was mobile, non-pulsatile and free from the overlying skin and the underlying muscle. Ultrasonography revealed a bilobed heteroechoic lesion in the left submandibular region with internal vascularity and multiple macrocalcification within it. During the procedure for surgically excising the swelling, we found that it was separate from the gland and vascular structures, had a sinus tracking over and around the left submandibular gland extending beyond the angle of mandible up to the root of a decayed left lower second molar tooth.

Second molar tooth germs from 2-day-old Swiss-Webster mice, grown in organ culture for 7 days in ascorbic-acid-deficient medium, synthesized about 65 % as much protein (measured by incorporation of [14C]proline during a 24-h pulse) as did ascorbic-acid-supplemented controls. The newly synthesized proteins from ascorbic-acid-deficient cultures contained only about 7% of the hydroxyproline content of the controls. Collagenase digestion of the newly synthesized proteins showed that collagen comprised the same fraction of the total protein synthesized under both culture conditions. This result indicates that the ascorbatedeficient cultures made significant quantities of underhydroxylated collagen. Partial characterization of the collagen alpha chains on carboxymethyl cellulose columns showed an α1/α2 ratio of about 5, suggesting that at least two different species of collagen were synthesized. The α1/α2 ratio of the chains recovered from the ascorbate-deficient cultures was also about 5 but the chains were slightly underhydroxylated and the total amount of these chains which could be identified accounted for only a small fraction of the total collagen which was synthesized. A large fraction of the synthesized collagenous protein was found in the culture medium, mostly in the form of lower molecular weight peptides. It is concluded that most of the collagen which is synthesized by ascorbate-deficient tooth-bud cultures is not utilized by the component tissues, but is probably degraded and released into the medium.

Complex Odontoma

ABSTRACT The most common odontogenic tumor is odontoma comprising 22% of all the cases. They show no gender predilection, are most often diagnosed in the second decade of life. They are preferentially located in the upper maxilla, particularly in the anterior sector. These are of two types complex and compound. Complex odontoma is a less prevalent than compound (1:2). Their apparent eruption in the oral cavity is rare. We hereby report a rare case of complex odontoma (intraosseous type) associated with impacted lower permanent second molar. These lesions are mostly asymptomatic and constitute casual finding on X-ray indicated for other reasons. The most common clinical manifestation is absence of impacted tooth and the presence of tumor. Treatment consists of surgical removal of tumor with impacted tooth. The prognosis is very good with least tendency toward relapse. How to cite this article Gangwar A, Pant B, Garkoti PD.
