Management of temporo-mandibular joint ankylosis using different surgical approaches.

Comparison of gap arthroplasty (GAP), interpositional arthroplasty (IAP) and distraction osteogenesis (DO) simultaneous with interpositional arthroplasty (DO+IAP) in management of TMJ ankylosis is of interest to dentists. The study comprised 36 individuals with TMJ ankylosis, 16 of whom were female and 20 of whom were male. Both prior to and following surgery, the maximum inter-incisal opening (MIO) and facial pattern were noted. The postoperative MIO was 33.23 ± 1.23mm, 35.24 ± 1.11mm and 38.24 ± 1.34mm in GAP, IAP and DO+IAP respectively. Data is statistically significant with high MIO observed in DO+ IAP technique and low MIO in GAP technique (p < 0.005). In addition to lengthening the mandible, concurrently processed interpositional arthroplasty alongside DO for TMJ ankylosis corrects gross asymmetry of the face, occlusal mal-alignment, midline change, and creates room for previously un-erupted teeth to emerge.

Effectiveness of low-level laser therapy after surgical removal of impacted mandibular third molars: A randomized clinical trial.

Introduction: The low-level laser therapy has been accepted globally as cell bio-modulator, used to reach ideal therapeutic effects, acting in the reduction of the pain response, with anti-inflammatory effects, stimulating local micro-circulation and wounds repair, promoting a rapid recovery, which brings a better quality of life to the patient. In this study, we aim to to determine the effectiveness of low-level laser therapy on reducing the pain and swelling after removal of impacted third molars. Materials and Methods: In this present prospective randomized clinical study, third molar surgeries were performed in thirty patients who were divided into two equal groups (placebo group and study group) a placebo group with routine treatment and a study group with low-level laser therapy which was applied both intraorally and extraorally after the surgical extraction of mandibular third molar. Results: The parameters such as postoperative pain, edema, and trismus were assessed on 1st and 7th day. All these parameters showed statistically significant results in patients with low-level laser therapy. Conclusions: Low-level laser therapy was effective in reducing the postoperative pain, edema, and trismus in the third molar surgeries.
