Angular deformities of the lower limbs are commonly encountered deformities in pediatric orthopedic clinics. The values of the tibiofemoral angle undergoes changes as the child grows and these changes are self-limiting. The aim of the study is to establish the normal variation of knee angles of children between 2 and 12 years of age in Enugu metropolis and to establish any correlation between the knee angles and the intermalleolar distances (IMDs). ⋯ The physiological changes in the knee angle (tibiofemoral) follow a similar pattern as established in the literature and there was positive correlation between IMD and the tibiofemoral angle.

The incidence of traumatic dental injuries is affected by social, environmental, and socioeconomic variables. For this reason, epidemiological studies are an important tool for increasing social consciousness and guiding the necessary precautions about trauma. ⋯ Early intervention is important for the prognosis of the injured tooth. However, except for severe injuries, the rate of referral to the clinic after trauma was low. Therefore, the level of social awareness and knowledge of trauma should be increased.

Periodontitis and peri-implantitis are irreversible destructive diseases of periodontal and peri-implant tissues. This study aimed to determine the receptor expressions of peroxisome proliferative-activated receptor (PPAR)-γ, retinoid X receptor (RXR)-α, vitamin D receptor (VDR), and cyclooxygenase (COX)-2 in diseased tissues around teeth and dental implants. ⋯ The results revealed that RXR-α and VDR levels were higher, while PPAR-γ and COX-2 levels were lower in the healthy group and periodontitis and peri-implantitis groups resulting in similar expressions in the tested parameters.
