ABSTRACT
Canalicular adenomas are uncommon benign salivary gland neoplasms of the oral cavity. They are typically located on the upper lip, buccal mucosa and infrequently found on the palate and derived from minor salivary glands. Intra-mandibular localization of canalicular adenoma is extremely rare. Due to benign character of the tumour, canalicular adenomas rarely present with bone erosion. Histologically, trabecular type of basal cell adenoma, pleomorphic adenoma and polymorphous low-grade adenocarcinoma should be discriminated from canalicular adenomas. A-56- year old female patient with asymptomatic intra-mandibular canalicular adenoma was presented. The lesion was managed surgically under local anesthesia and 2 year's follow up was uneventful. Only two other intra-mandibular canalicular adenoma cases have been reported up till now. This case report describes the third intra-mandibular canalicular adenoma, and reviews the literature.

OBJECTIVE: To evaluate the dentoalveolar, skeletal, and soft tissue effects of the Zygoma-Gear Appliance (ZGA) when used for bilateral distalization of the maxillary molars. MATERIALS AND METHODS: The study group included 15 patients (mean age, 15.87 ± 1.09 years; range: 14-18 years) treated with the ZGA system supported with zygomatic anchorage miniplates. The changes due to the distalization were evaluated from the lateral cephalometric films taken before and after distalization by means of a paired t-test. RESULTS: The mean treatment period required to achieve a Class I molar relationship was 5.21 months. The distalization amount of the maxillary molars was 4.37 ± 2.15 mm (P < .001), and, thus, the rate for the distal movement of the molars was 0.84 mm per month. Maxillary first molars showed a slight intrusion (0.50 mm) (P > .05), while distal tipping was only 3.30° ± 2.31° (P > .05). Furthermore, there was a decrease in overjet (-0.50 mm) (P > .05), indicating that there was no anchorage loss with use of the ZGA. CONCLUSIONS: Maxillary molar distalization without anchorage loss can be achieved in a short time with ZGA.

Dental trauma sometimes causes fractures in the maxillary anterior teeth leading to esthetic, functional and phonetic problems. In this report, we describe the treatment of central and lateral incisors simultaneously subgingivally fractured due to dental trauma. Treatment involved flap surgery, reattachment and splinting of the fractured fragments with glass-fibre and composite resin. This reattachment technique, which uses advanced adhesive systems, is an option that offers satisfactory esthetic and functional outcomes.
