To evaluate the systemic effects of low level laser therapy (LLLT) on the early stages of bone repair after implantation of poly-L-lactic/polyglycolic acid (PLLA-PGA) screws 24 rabbits were randomly allocated to one of two groups, experiment or control. Each animal underwent implantation of one 5 × 1.5 mm PLLA-PGA screw in each tibia (right and left). The experiment group received infrared laser irradiation (830 nm, 4 J, 100 mW, 10.1 s) over the right paw immediately after implantation and every 48 h thereafter, for a maximum of seven sessions. The control group was not irradiated. Both groups were divided into three subgroups according to the observation period (5, 15, or 30 days), after which animals were euthanized. The results observed in the left paw of experimental animals were compared with the left paws of control animals. We also compared the right and left paws of experimental animals so as to compare local and potential systemic effects. Bone specimens were analyzed to assess the extent of peri-implant bone formation, quantitative analysis revealed greater bone formation in the left tibia of experimental animals as compared to controls on 5-day follow-up. Descriptive analysis revealed slightly larger and thicker trabeculae in the irradiated animals at 5 days post-procedure. There were no significant differences at any other point in time. As used in this study, LLLT had a positive systemic effect on the early stages of bone formation.

Lipomas are benign tumors of mature adipocytes unusual in the oral and maxillofacial region. The average size of cheek lipomas in the literature ranges from 1.5 to 2.5 cm, with the maximum size of 5 cm. Their etiology remains unclear. Lipomas present, clinically, as well circumscribed, slow growing, painless masses, usually treated by complete excision. The aim of this paper is to present a 78-year-old Caucasian male patient with a huge cheek lipoma compromising facial esthetics and treated through an intraoral excision. Postoperative period was uneventful with no signs of recurrence. Concluding, the intraoral approach is a relatively simple technique that should be taken into account when considering the surgical removal of cheek lipomas.

There were no important differences in the σ1 analysis and the displacement between the SFP and CFP. The differences in marginal bone level reported between SFP and CFP in some clinical studies may not be related to a mechanical factor.

Cervical necrotizing fasciitis is a rare polymicrobial infection characterized by extensive, rapidly spreading necrosis of the subcutaneous tissue and superficial fascia. This paper describes a case of necrotizing fasciitis of odontogenic origin in a 55-year-old man who presented with a dental abscess associated with an impacted lower premolar after prolonged use of removable dentures. Treatment included extensive surgical debridement, systemic antibiotics, and intensive care. This case highlights the importance of proper evaluation and diagnosis before the rehabilitation of edentulous patients. A panoramic radiograph can show the presence of an impacted tooth, which must be removed before installation of a removable denture to prevent further complications like that.
