RESUMO
Fractures of temporomandibular joint (TMJ) may be caused by indirect trauma where force of trauma is transmitted to the mandibular condyle from a blow elsewhere or in other situations may also result from direct trauma. TMJ trauma in children is usually accompanied with pain, swelling, limited jaw movement and other additional findings. This report highlights a case of post traumatic trismus successfully managed with Brisement force - gradual tractional forces applied to the temporomandibular joint.

OBJECTIVES: This study compares the efficiency of manual K-files and rotary ProFiles in cleaning capacity and instrumentation time in primary molar root canals. MATERIALS AND METHODS: Seventy-five maxillary and mandibular primary molar root canals were instrumented with ProFiles and K-files in the step-back manner from size #10 to #40. The teeth were decalcified, dehydrated and cleared, and analyzed for the presence of dye remaining on the root canal walls, which served as an evidence of cleaning capacity of both the techniques. RESULTS: The results showed a significant difference in the cleaning capacity of the root canals with ProFiles and K-files, in apical and coronal thirds of the root canal. ProFiles have been found to be more efficient in cleaning the coronal thirds and K-files in cleaning apical thirds of the root canals. Both the techniques were almost equally effective in cleaning the middle thirds of the canals. The time taken during the cleaning of the root canals appeared to be statistically shorter with K-files than profiles.

OBJECTIVES: To assess the relative position of the mandibular foramen (MF) and to evaluate the measurement of gonial angle (GoA) and its relationship with distances between different mandibular borders in growing children between 3 and 13 years of dental age. MATERIALS AND METHODS: The radiographs were traced to arrive at six linear and two angular measurements from which the relative position of the MF was assessed and compared in different age groups to determine the growth pattern of the mandible and changes in the location of the MF. RESULTS: The distances between the MF and the anterior plane of the ramus were greater than that between MF and posterior plane of the ramus through all stages. There was a maximum increase in the vertical dimensions of the mandible compared with the horizontal dimensions, particularly in the late mixed dentition period. CONCLUSION: The mandible and its growth did not alter the position of the MF, both vertically and horizontally, in relation to different landmarks, and more obtuse GoA indicated an increased growth potential of the mandible. This has major implications in the inferior alveolar nerve block technique when used in children.
