A 20-year-old male presented with a small swelling in the vestibular area of the right lower second mandibular molar region. Clinically, the area was slightly tender and the tooth had grade two mobility. There was no nerve deficit or adenopathy in the head and neck. Vitality testing of the tooth revealed the tooth to be vital. Radiographically, the tooth had a relativelydefined radiolucent lesion in the periapex with resorption of the mesial and distal root apices. We have discussed the probable treatment plan with the patient and going for extraction of involving tooth and excision of whole lesion with complete margin which is suspected as ameloblastoma.

Primordial odontogenic tumor (POT) is a recently designated benign mixed epithelial and mesenchymal odontogenic tumor and only sixteen cases have been reported worldwide till now. Here we report an another case of POT in a 14–year old boy who presented with an asymptomatic buccal enlargement in the right maxillary region for past 4–5 months. A well-defined, unilocular, radiolucent lesion with impacted teeth was observed radiographically. A detailed account of clinico-radiographical and histolological differential diagnoses along with an updated literature review has been presented.

A 24 year-old male was presented for the diagnosis of an asymptomatic bony expansion in relation to the right maxillary canine and first premolar. The unilocular radiolucent lesion with central foci of calcification had caused divergence of canine and first premolar roots without any resorption. This case report details a diagnosis of two distinct disease processes of different cellular origin namely, focal cemento-ossifying dysplasia and adenomatoid odontogenic tumor in a previously unreported concomitant and contiguous relationship. The diagnosis was determined by a combination of clinical, radiographic, histopathological and surgical evidence. This case highlights two points, first the need to examine all mixed radiolucent-radiopaque lesions with advanced imaging techniques to assess the number and extent of the lesions prior to treatment planning. Second a likely role of periodontal ligament as the tissue source for odontogenic epithelial cells and mesenchymal stem cells required for the development of odontogenic tumors and cemento-osseous dysplasias.

ABSTRACT The adenomatoid odontogenic tumor is a benign, non-invasive tumor and has a slow growth. Its preferred location is the anterior maxillary area, most often causing root displacement, more rarely resorption and mostly affects young women. Being asymptomatic, this injury is discovered upon routine radiographic examination, in which, in most cases, a unilocular, radiolucent image is observed and it may have some degree of calcification within the lesion. This work aims to report the case of a 14-year-old patient who attended the Lauro Wanderley University Hospital (UFPB), complaining of increased volume over a period of 8 months, in the region of non-vital tooth 21. The CT scan showed well-delimited unilocular, radiolucent lesion, with buccal cortex resorption. The proposed treatment plan involved enucleation, followed by peripheral ostectomy and bone graft with alloplastic materials. Because of its benign character, encapsulated and slow growing, the treatment of choice for adenomatoid odontogenic tumor is conservative, the surgical enucleation of the injury being advocated. The excised piece was sent for histopathological analysis, where the AOT diagnosis was confirmed. After 7 months, new bone formation was observed without signs of recurrence.

Introduction: Adenomatoid odontogenic tumor (AOT) is a rare tumor of epithelial origin, and usually presents as a unilocular radiolucency in the maxillary anterior region in adolescent females. Observation: A 31-year-old Japanese male, having a large adenomatoid odontogenic tumor from the right molar region to the left anterior region of the mandible showing root resorption of the neighboring teeth, was presented to the hospital. The lesion was totally resected under general anesthesia. Commentary: AOT may cause displacement of the neighboring teeth. But root resorption is a very rare finding. AOTs are relatively small in size. Conclusion: The patient was under follow-up and had not shown any signs of recurrence 12 months after surgery.

Abstract Background The vertical thickness of the peri-implant mucosa is associated with the amount of post treatment marginal bone loss. However, the variations in mucosal thickness at the different edentulous sites have been sparsely documented. The purpose of the study was to conduct a survey of the frequency distribution of variations in mucosal thickness at the different sites of the edentulous alveolar ridge and to compare them according to gender. Our study included 125 partially edentulous patients having a total of 296 implant sites. Cone-beam computed tomography (CBCT) scans were obtained by placing a diagnostic template with a radiopaque crown indicator on the ridge to determine the mucosal thickness at the crest of the alveolar ridge. Results The mucosal thickness was 3.0±1.3 mm in the maxilla, which was significantly greater than the mucosal thickness of 2.0±1.0 mm in the mandible (p<0.001). In both the maxilla and the mandible, the mucosa was the thickest in the anterior region, followed by the premolar and molar regions. Sites were further classified into two groups based on whether the mucosal thickness was greater than 2 mm. In the mandible, more than half of the sites showed a mucosal thickness of 2 mm or less. Conclusions Although this study was a limited preoperative study, the vertical mucosal thickness at the edentulous ridge differed between the maxillary and mandibular regions. The majority of sites in the mandibular molar region had a mucosal thickness of less than 2 mm. Practitioners might be able to develop an optimal dental implant treatment plan for long-term biologic and esthetic stability by considering these factors.

Background: Excessive use of smartphones may be associated with behavioral and physical health changes and might cause musculoskeletal alterations in the head and neck region. Objective: To evaluate the prevalence of smartphone addiction in college students and its correlation with symptoms of head and neck pain and masticatory and trapezius muscle activity while resting, before and after smartphone use. Methods: Twenty university students participated in the study. They answered the Smartphone Addiction Scale and the Fonseca Anamnestic Index. Next, the participants were seated and prepared for electromyography through the placement of surface electrodes on the masseter, temporal, and trapezius muscles. Rest condition data were collected for 10 seconds before and after 30 minutes of smartphone use. Results: The results showed that 35% of the evaluated individuals were classified as smartphone addicted and 35% reported no head or neck pain in the previous 30 days. There was no association between smartphone use and head and neck pain. In the electromyography, there was an increase in RMS values after smartphone use in the right and left masseter muscles and the left trapezius. Conclusion: College students presented a high prevalence of smartphone addiction and head and neck pain, but these were not statistically associated. There was a change in muscle activity only in the right trapezius muscles before and after 30 minutes of smartphone use. These findings are contrary to the current belief that the use of smartphones correlates with pain in the neck region and changes in the electrical muscle activity, leading to fatigue in the cervical muscles.
