Unrecognized Lower Jaw Fracture in a Physically and Emotionally Abused Child.

Diagnosing child abuse still poses a challenge for healthcare professionals. We will present a case in which a physically and emotionally abused four-year-old boy had an undiagnosed lower jaw fracture for almost eight months. The child first presented with a peri-mandibular swelling and was treated with antibiotics prescribed by his doctor of dental medicine. After not having responded to antibiotic treatment, the boy was referred to the Department of Oral and Maxillofacial Surgery, accompanied by his birth mother. The deciduous mandibular molars with deep cavities were extracted since we thought that they were the reason for swelling. After several visits with his foster mother, the child was finally diagnosed with a lower jaw fracture and a psychosomatic disorder. Physical abuse by his birth parents was later on confirmed, and the consequences were insufficient growth, non-perception of pain and reduced speech development. After having been with his foster mother for almost a year, the child learned to complain when he was in pain. This report emphasizes the importance of taking a detailed medical history along with a thorough clinical examination.

Anatomical Variations of the Bifid Mandibular Canal on Panoramic Radiographs in Citizens from Zagreb, Croatia.

BACKGROUND: The bifid mandibular canal (BMC) is an anatomical variation with reported prevalence ranging from 0.08 to 65%. Identifying anatomical variations of mandibular canal is very important in order to prevent possible complications during oral surgical and other dental procedures. OBJECTIVES: The aim of this study was to determine the prevalence and to classify the morphology of BMCs using digital panoramic radiographs. MATERIAL AND METHODS: A retrospective study was conducted that included 1008 digital panoramic radiographs (412 female and 596 male) used to identify the type of BMC. Panoramic radiographs were analyzed by three oral surgeons and one dentist, and BMCs were classified into six different types, 4 types according to Langlais et al. (types 1-4), and two new types (types 5 and 6) described by authors. RESULTS: The prevalence of BMC was 4.66% (n=47), with no significant differences in gender between BMC types (P=0.947; χ2=0.74). The prevalence of type 1 BMC was 0.79% (n=8), type 2 2.08% (n=21), type 3 0.30% (n=3), type 4 0% (n=0), type 5 0.89% (n=9) and type 6 0.60% (n=6). CONCLUSION: This study revealed a relatively high prevalence of BMCs among Zagreb citizens. Furthermore, two new types of BMCs were described. These results stress the importance of a careful and thorough radiographic analysis prior to each invasive procedure in the mandible.

Primary School Teachers' Knowledge on Tooth Avulsion.

OBJECTIVE: Permanent teeth trauma is most frequent in children aged 7-9 years, and the primary school teachers (PSTs) are often the first to notice it. The aim of this study was to evaluate the competence in tooth avulsion clinical issues and knowledge on dental trauma of PSTs, as they can occasionally take on the role of school nurses. MATERIAL AND METHODS: Questionnaires were handed to 312 PSTs from 24 randomly selected primary schools in Zagreb, Croatia. An algorithm was designed for PST competence assessment. RESULTS: Response rate amounted to 81.37% (N=255). Only 3.14% (N=8) of the PSTs would replant the permanent tooth properly and only 43.92% of them (N=112) would immediately take the child to a doctor of dental medicine. Dry tissue, as a transport medium for an avulsed tooth, was chosen by 50.20% (N=128) of the respondents. Altogether, 4.71% (N=12) of PSTs were graded as competent in case of child's tooth avulsion. CONCLUSION: These results provided significant implications for school health, showed the educators' serious lack of knowledge in cases of dental trauma and stressed a need for continuous education of PSTs on the topic.

A Large Cheek Hematoma as a Complication of Local Anesthesia: Case Report.

Hematoma is among less frequent complications which occur following local anesthesia. The posterior superior alveolar nerve block and inferior alveolar nerve block are known to be accompanied with a higher incidence of positive aspiration compared to all infiltration and block anesthesia techniques in oral surgery. We present the case of an otherwise healthy 8-year-old boy who experienced a large cheek hematoma after a routine infiltration anesthesia in the maxilla. Firstly, he was mistakenly treated under the diagnosis of type1 allergic reaction. Subsequently, the topical therapy for an evident, large hematoma was unsuccessful. Ultimately, incision of the infected hematoma and antibiotic therapy were crucial for its resolution. Early recognition of clinical signs of hematoma is of utmost importance for the surgeon in order to treat the patient adequately.

Tongue metastasis as an initial presentation of renal cell carcinoma.

Aim Distal metastases to oral cavity are very rare. Adenocarcinoma, renal cell carcinoma (RCC) and squamous cell carcinoma are the most common metastatic tumours. The aim of this study was to assess the diagnostic relevance of metastatic renal cell carcinoma on tongue manifestations in large patient series. Methods A patient with distal RCC metastases to the tongue and neck lymph nodes as the first manifestations of malignancy was presented. Also, all reports described during 106-year period relating to distal RCC metastasis to the tongue were evaluated. Results In the presented patient, initial presentation of RCC was metastasis to the tongue. Three months after nephrectomy, tongue tumour resection and radical neck dissection were performed. Histopathological analysis confirmed RCC metastasis. Postoperatively, the patient underwent radiotherapy and polychemotherapy. Tongue metastasis from RCC is extremely rare with only 51 cases reported during the 106-year period. In only 7 patients tongue metastasis was reported as an initial presentation of RCC. Conclusion The RCC metastasizing to the tongue is extremely rare and thus it poses a diagnostic challenge especially when it is the first sign of malignancy. Therapeutic decisions should maximize patient comfort and minimize morbidity considering the poor long-term prognosis.

New Findings on Local Tramadol Use in Oral Surgery.

In modern times, all procedures in oral surgery need to be painless and management of postoperative pain needs to be adequate. The surgical extraction of the third molar or alveolectomy of the wisdom tooth is one of the most common surgical procedures carried out in oral surgery and it includes rising a flap, bone removal and suturing. These surgical procedures usually cause swelling, trismus and moderate to severe pain. Third molar surgery is often used as a model in clinical trials that are directed toward reducing postoperative pain and improving its management. Tramadol is a well-known central acting opioid analgesic that produces analgesia against multiple pain conditions such as postsurgical pain, obstetric pain, terminal cancer pain, pain of coronary origin and neuropathic pain. Tramadol is an atypical opioid. When administered locally, it has both analgesic and anesthetic properties. The aim of this paper was to present new findings on local effects of tramadol in oral surgery.

Ambulatory oral surgery: 1-year experience with 11680 patients from Zagreb district, Croatia.

AIM: To examine the types and frequencies of oral surgery diagnoses and ambulatory oral surgical treatments during one year period at the Department of Oral Surgery, University Hospital Dubrava in Zagreb, Croatia. METHODS: Sociodemographic and clinical data on 11680 ambulatory patients, treated between January 1 and of December 31, 2011 were retrieved from the hospital database using a specific protocol. The obtained data were subsequently analyzed in order to assess the frequency of diagnoses and differences in sex and age. RESULTS: The most common ambulatory procedure was tooth extraction (37.67%) and the most common procedure in ambulatory operating room was alveolectomy (57.25%). The test of proportions showed that significantly more extractions (P<0.001) and intraoral incisions (P<0.001) were performed among male patients, whereas significantly more alveolectomies and apicoectomies were performed among female patients (P<0.001). A greater prevalence of periodontal disease was found in patients residing in Zagreb than in patients residing in rural areas. CONCLUSION: The data from this study may be useful for planning of ambulatory oral surgery services, budgeting, and sustaining quality improvement, enhancing oral surgical curricula, training and education of primary health care doctors and oral surgery specialists, and promoting patients' awareness of the importance of oral health.

Gastric adenocarcinoma metastases to the alveolar mucosa of the mandible: a case report and review of the literature.

Malignant tumours rarely metastasize to the oral cavity. When they do, such metastases may arise from various locations including the lung, breast, kidney, prostate and colon. Soft tissue oral metastasis from gastric adenocarcinoma is extremely rare, and limited information exists regarding the presentation and work-up of metastatic gastric carcinoma into the oral soft tissue. We present an unusual case of a 70-year-old man and review the records of 17 cases of soft tissue oral metastasis from gastric carcinoma in the English and Japanese literature. Metastatic lesions from all sources are typically diagnosed in patients in their fifth to seventh decade, with the most common sites of soft tissue metastasis being the gingiva and alveolar mucosa of the mandible. In almost one quarter of patients a metastatic lesion in the oral cavity is the first manifestation of an undiscovered primary malignancy. They grow rapidly and tend to bleed and ulcerate. Because of their rarity and clinical characteristics, gastric metastatic tumours in the oral cavity are challenging to diagnose. Inflammatory and reactive lesions are common in the oral cavity and they should be considered in the differential diagnosis. Careful examination with a high degree of clinical suspicion, as well as a multidisciplinary approach is suggested.
