Cutaneous Sinus

Odontogenic cutaneous sinus tract (OCST) (synonyms: odontogenic cutaneous fistula, odontogenic subcutaneous granuloma, etc.) is an abnormal tube-shape formation which serves as a pathway for pus drainage from the locus of tooth–associated infection to the cutaneous lesion. OCST is a collective term and commonly is manifested in six cutaneous forms: as dimpling with fistula, cutaneous infiltration, nodule, suppurated nodule, abscess, or even cyst-like cutaneous formation. The purpose of this paper is to present the diverse clinical and radiological appearance (cone-beam computed tomography [CBCT] and ultrasound [US]) of single and multiple OCSTs based on the literature and our four cases. As long as limited publications present the ultrasound appearance of the OCSTs, we will focus on meticulous description of sonograms as well, giving a possibility for oral and maxillofacial surgeons to understand all advantages of that type of non-ionizing radiation diagnostics, avoiding misdiagnosis and mistreatment of OCSTs. Case 1: A 24-year-old male with OCST to the left mandibular region from the lower left first molar. Cutaneous lesion of OCST manifested as a transition stage from cutaneous infiltration to abscess. Case 2: A 41-year-old male with odontogenic cutaneous fistula of the right mandibular body region from the lower right second molar. It`s manifested as deep dimpling with active fistula. Case 3: A 45-year-old male with unilateral multiple OCSTs: 1) odontogenic cutaneous fistula of the left cheek from the left second maxillary molar and 2) a scar from a surgically treated OCST located in the projection of the left mandible from the tooth #3.6. Case 4: An 18-year-old male with OCST to left nasolabial fold and cheek from the upper left first molar. The pathology manifested as a subcutaneous abscess first and a nodule after the abscess lancing. These cases highlight the diverse cutaneous manifestations of the OCSTs. The US appearances of different parts of the OCST are presented, the popular terminology for the same cutaneous lesions are discussed, the new terms are proposed, and the treatment strategies based on histologic results are debated.

Genetic And Environmental Factors

Congenital missing permanent second molar is an extremely rare condition. Non syndromic mandibular second molar agenesis associated with other anomalies has occasionally been reported in literature, but isolated sporadic cases are rarely observed. Number of interactions between genetic and environmental factors during the process of tooth development might be the causative etiology for agenesis. This report presents an isolated case of hypodontia with absence of bilateral mandibular second molar agenesis in a healthy 18 year old female patient is presented and literature review on prevalence of most missing teeth with incidence of missing second molar in various regions of the world and in various regions of Indian continent is presented. No such case has been reported in Indian literature so far.

Intentional replantation is a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this article, intentional replantation is described and discussed as a treatment approach for failed root canal treatment with broken instrument periapically in mandibular second molar.

Introduction: Buccal shelf bone screws have become increasingly popular as a preferred method of skeletal anchorage in the mandibular arch. Anatomic variations and clinical experience suggest that width and slope of the bone at buccal shelf vary in different population groups, with some individual variations. Aims and Objectives: The objective of this study was to evaluate angulation of the bone screw of mandibular buccal shelf area, total bone width, thickness of the cortical bone, and proximity to neurovascular structures. Materials and Methods: Cone-beam computed tomography scans were used to obtain measurements of the buccal shelf region of 35 patients (18 females, 17 males; mean age, 23.6 years). Measurements were taken at three locations (L1, L2, and L3) and total bone width was measured at two levels from the cementoenamel junction (CEJ, H1 and H2). Bone screws were virtually placed and their proximity evaluated from digitally traced inferior alveolar neurovascular bundle. Results: Permissible angulation for placement of buccal shelf bone screw considering the safety distance from the root and avoiding excessive buccal projection to minimize cheek irritation was found to be 74.48 (SD ± 4.26). Total bone width was maximum at the distobuccal cusp of mandibular second molar (L3H2; 6.40 ± 1.35) when measured at the level of 8 mm from the CEJ. Bone screws were well within the safety range from causing any iatrogenic damage to the inferior alveolar neurovascular bundle at all the three aforementioned locations. Conclusion: Thus, area buccal to the mandibular second molar region seems to be the most favorable site for placement of buccal shelf bone screws in Indian patients.
