Delayed replantation of an avulsed tooth after 5 hours of storage in saliva: a case report

This article reports a clinical case of a 8-year-old boy, who underwent an avulsion of the upper left central incisor. The avulsed tooth was kept in the oral cavity in direct contact with saliva for 5 h from the moment of trauma until its replantation. Treatment guidelines for avulsed mature permanent teeth were followed. The clinical and radiographic findings after 2 years revealed absence of root resorption, ankylosis or mobility of the replanted tooth.

A stepped approach for the management of symptomatic internal derangement of the temporomandibular joint

BackgroundInternal derangement is the clinical and pathological condition of disc displacement of the temporomandibular joint. Management of these cases involve conservative and surgical treatment options. Minimally invasive surgical procedures namely arthrocentesis and arthroscopy are promising techniques in the management of internal derangement. However patient selection algorithms, indications for minimally invasive procedures and details of the techniques should be further studied for safe and cost effective management of these cases.This manuscript aims to retrospectively analyze the significance of a stepped surgical treatment approach (arthrocentesis under local anaesthesia as the first line of treatment, followed by arthroscopic lysis and lavage under general anaesthesia in unresolving cases) of internal derangement with or without osteoarthritis.MethodsThis is a retrospective cohort study. Case notes of 1414 patients that were managed with a standard protocol were reviewed. Appropriate inclusion and exclusion criteria were set. Thirty-three patients were eligible for inclusion. Parameters recorded were pain-free inter-incisal opening, spontaneous pain, pain on function, difficulty on chewing, and perceived disability on jaw movements. Pre-operative and post-operative (at the end of the follow up period) pain free maximum interincisal opening values were compared with paired t test and the subjective parameters were evaluated with Chisquare analysis. Treatment outcome and success rate according to American Association of Oral and Maxillofacial Surgeons were descriptively shown.ResultsInterincisal opening values increased, and the number of patients with severe or medium rated subjective parameters were reduced at discharge. These improvements were found to be statistically significant. Clinical (Wilkes) staging of internal derangement pre-operatively and at discharge remained either unchanged or was lower. Treatment outcome and success according to American Association of Oral and Maxillofacial Surgeons criteria was 94%.ConclusionThe stepped approach for the management of symptomatic internal derangement with or without osteoarthritis is a successful treatment strategy with favourable therapeutic outcomes.

The effect of teeth in mandibular fracture lines

BACKGROUND/AIM The decision to retain or extract teeth in the line of mandibular fractures has been a subject of debate in the scientific literature, and there is a need for further evidence to clear this issue. Thus, the aim of this study was to investigate the effects on healing of teeth in the line of mandibular fractures in order to contribute to the field. MATERIAL AND METHODS The case notes of 100 patients with teeth in the line of 106 mandibular fractures were reviewed. Open reduction and rigid internal fixation (ORIF) was used if elastic intermaxillary reduction failed to achieve a satisfactory occlusion and/or anatomical reduction in the fragments as assessed by orthopantomogram (OPG) and clinical examination. The remaining cases had maxillomandibular fixation (MMF) with an arch bar and bridle wire. RESULTS Three of the 106 teeth involved in the fracture lines healed with complications. In the cases where the teeth had been removed prior to fracture treatment, or in cases of delayed extractions, no complications were noted. CONCLUSION The factors which should be considered for removal include the condition of the teeth and alveolar bone, the timing and the type of treatment. This decision should be made on an individual basis considering potential risks to avoid complications.

Aktinik şelitis tedavisinde 5-fluorourasıl (5-fu) kullanımı: derleme ve iki olgunun sunumu

Actinic (solar) cheilitis is an epithelial precancerous lesion with a predilection of lower lip rather than upper lip. Clinically they may be undistinguishable from squamous cell carcinomas. Therefore actinic cheilitis should not be left untreated and the effected area should be protected from exposure to excess sun light. Two patients complaining of chronic ulcers and burning sensation on their lower lips were referred to the oral surgery clinic. Clinical examination revealed keratotic areas and superficial ulcers on lower lip vermillion. Patients’ history and the clinical findings led us to a clinical diagnosis of actinic cheilitis in both cases. The diagnoses were confirmed histopathologically, treatment was with topical 5-FU and one of the cases is still under our review. Clinical appearance of actinic cheilitis can be similar to lip carcinomas and there is the risk of transformation to squamous cell carcinoma. For this reason it is imperative that a biopsy is taken promptly to confirm the diagnosis. Recurrence is possible after treatment and this necessitates regular review appointments. Patient compliance is a must, and to improve this, treatment options should be discussed with the patient and their preferences should be considered. OZET Aktinik (solar) selitis daha cok alt dudakta gorulen epitelyal prekanseroz bir olusumdur. Klinik olarak, skuamoz hucreli karsinomdan ayrilmasi guc olabilir.

Çene kemiklerinin yeni tehlikesi: bisfosfonatlar

Bisphosphonate compounds have been used for the improvement of the lives of cancer patients by reducing complications such as hypercalcemia. They are preferred to treat bone metastases of solid tumors such as breast, prostate and lung cancer, and also utilized in the management of lytic lesions of multiple myeloma. Intravenous administration of high doses of bisphosphonates for the management of benign conditions occasionally lead to the development of osteonecrosis of the jaws. In many cases lesions appear spontaneously, or following an infection or a dental extraction. At present, there is no definite treatment for this particular druginduced necrosis of bone except conservative debridement of bone lesions, oral antibiotics and local irrigations. It is important to recognize the clinical and radiographic features of the bisphosohonate osteonecrosis of the jaws in order to provide early diagnosis and to improve the care of these patients. OZET Bisfosfonat bilesikleri malignansiye bagli olarak gelisen hiperkalseminin duzenlenmesinde ve ayrica, meme, prostat ve akciger kanserlerine bagli tumorlerin ve multipl myelomaya bagli metastatik lezyonlarin tedavisinde kanser hastalarinin hayat kalitelerini iyilestirmek amaciyla kullanilmaktadir. Bisfosfonatlarin yuksek dozlarda intravenoz olarak uygulanmalari nedeniyle ilaca bagli bir yan etki olarak cenelerde osteonekroz gelisebilmektedir. Lezyonlar kendiliginden olusabildigi gibi, bir enfeksiyon ve dis cekimi genellikle olayi hizlandirmaktadir. Ilaca bagli olarak gelisen bu ozgun kemik nekrozu icin henuz kesin bir tedavi bulunmamaktadir. Konservatif yaklasim uygulanan vakalarda, kemigin aciga cikmis oldugu hastalarin buyuk bolumunde oral antibiyotikler, antienflamatuvarlar ve acik yara bolgesinin lokal irrigasyonu onerilmektedir. Bisfosfonat osteonekrozuna ait klinik ve radyografik ozelliklerin iyi bilinmesi ve bu tur hastalarda klinik ve radyolojik belirtilerin degerlendirilmesi, erken tani ve tedavi acisindan da onem tasimaktadir.
