1/4. Metal piercing through the tongue and localized loss of attachment: a case report.The piercing of intraoral structures to accommodate different types of jewelry has increased in popularity in the last few years. The association of an intraoral piercing with localized periodontitis is not well documented in the literature. A 22-year-old male presented to our clinic with a tongue stud placed through the mid-dorsum of his tongue. The inferior sphere was coated with plaque and calculus. Teeth #24 and #25 exhibited 6 mm interproximal probing depth and recession, horizontal radiographic bone loss, and tissue indentations consistent with the shape of the inferior ball of the tongue stud directly on the lingual surfaces of both teeth. The treatment consisted of an adult prophylaxis, flap curettage of the mandibular anterior region, oral hygiene instructions, and removal of the tongue stud. At our follow-up visit, the patient's oral hygiene had improved, he has removed the jewelry, and the attachment loss appears to have stabilized.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
2/4. Calculus-like deposit on the apical external root surface of teeth with post-treatment apical periodontitis: report of two cases.AIM: To report two cases in which calculus-like material was found on external root surfaces of (i) an extracted root and (ii) an apicected part of a root, both of which were removed due to post-treatment refractory apical periodontitis. SUMMARY: In each case, there was a fistulous tract, which did not heal after conventional root canal treatment. The first case did not heal even after apical surgery, and subsequent tooth extraction revealed calculus-like material on a root surface of complex anatomy. The second case showed radiographic signs of healing after apicectomy. histology of the apical biopsy revealed a calculus-like material on the external surface of the root apex. It is suggested that the presence of calculus on the root surfaces of teeth with periapical lesions may contribute towards the aetiology of failure. KEY learning POINTS: Biofilm on the external root surface has been implicated in the failure of apical periodontitis to heal, despite adequate root canal treatment. Calculus-like material was found, in two cases, on the root surface of teeth with post-treatment apical periodontitis, where the only communication externally was a sinus tract.- - - - - - - - - - ranking = 7keywords = periodontitis (Clic here for more details about this article) |
3/4. Generalized juvenile periodontitis in a thirteen-year-old child.There have been two previous cases reported in which children with a possible history of Prepubertal periodontitis (PP) developed Generalized Juvenile periodontitis (GJP) in their permanent dentitions at circumpubescent ages. This paper reports a case in which an apparently healthy 13-year-old girl, whose radiographs at 6 1/2 years of age showed horizontal bone loss around the primary molars, developed GJP. blood tests (CBC, WBC differential, fasting glucose level, serum alkaline phosphatase) and a gingival biopsy were performed to exclude possible systemic diseases that might have been associated with alveolar bone resorption. Neutrophil (PMN) chemotaxis (CX) and adhesion molecule CD11b levels were also examined. The results of these tests were all within the normal range. This case report illustrates that an apparently healthy patient with PP may develop advanced periodontitis at a circumpubescent age.- - - - - - - - - - ranking = 5keywords = periodontitis (Clic here for more details about this article) |
4/4. Calculus-like deposit at apex of tooth with refractory apical periodontitis.It is generally accepted that bacteria in or outside the root canal are the reason for apical periodontitis and endodontic failures. This case report presents a 60-year-old woman with a periapical lesion and a fistulous tract which did not respond to conventional root canal treatment. During periapical surgery, granulomatous tissue was removed and a calculus-like deposit was observed on the root surface. A radicular cyst was diagnosed. Nine months after this calculus-like deposit had been removed and the cyst enucleated, complete recovery of the bone had occurred. It is suggested that the presence of the calculus-like deposit at the apex of the tooth or its effects may in part have delayed the healing of the periapical inflammation in spite of apparently adequate endodontic treatment.- - - - - - - - - - ranking = 5keywords = periodontitis (Clic here for more details about this article) |
