Efficacy of dry needling in patients with myofascial temporomandibular disorders related to the masseter muscle

ABSTRACT

Objective

This randomized, single-center clinical trial aimed to compare the efficacy of superficial dry needling (SDN) and deep dry needling (DDN) in patients with myofascial temporomandibular disorder (MTMD) related to the masseter muscle.Methods: Forty patients showing MTMD with trigger points in the masseter muscle were randomly assigned to groups. Dry needling of the masseter muscle was performed once per week for three weeks. Pressure pain threshold (PPT) measurements, visual analog scale scores, and maximal jaw opening were assessed.Results: Both patient groups showed significant pain reduction, but the SDN group showed significantly better pain reduction. The PPT measurements obtained in the follow-up examinations at three and six weeks were significantly better than the values in SDN and DDN groups.Discussion: SDN showed better pain-reduction efficacy in patients with MTMD. Further research with a larger size sample and a longer follow-up period will help elucidate the benefits of SDN.     

Medication-related osteonecrosis of the jaw: An institution’s experience

ABSTRACT

Objectives

This study aimed to evaluate and report the outcomes associated with the management of patients who were treated surgically for medication-related osteonecrosis of the jaw (MRONJ).Methods: Demographic and medical profiles of patients with a diagnosis of MRONJ were created. The type of surgical treatment, complications, and treatment outcomes were identified.Results: Twenty-one patients with an average age of 68.42 years (range 40–90 years) were included. Nineteen patients had only mandible involvement, one patient had only maxilla involvement, and one patient had both mandible and maxilla involvement. Thirteen patients underwent marginal resections. Eight patients underwent segmental resection of the mandible with immediate reconstruction. Nineteen patients healed without any complications. Two patients who had undergone segmental resection of the mandible experienced postoperative complications and needed a second surgery to achieve primary closure.Discussion: Advanced MRONJ can effectively be treated with resective surgery in combination with medical treatment.     

Physical property investigation of contemporary glass ionomer and resin-modified glass ionomer restorative materials

Objectives

The objective of this study was to investigate selected physical properties of nine contemporary and recently marketed glass ionomer cement (GIC) and four resin-modified glass ionomer cement (RMGI) dental restorative materials.

Materials and methods

Specimens (n = 12) were fabricated for fracture toughness and flexure strength using standardized, stainless steel molds. Testing was completed on a universal testing machine until failure. Knoop hardness was obtained using failed fracture toughness specimens on a microhardness tester, while both flexural modulus and flexural toughness was obtained by analysis of the flexure strength results data. Testing was completed at 1 h, 24 h, 1 week, and then at 1, 3, 6, and 12 months. Mean data was analyzed with Kruskal-Wallis and Mann-Whitney (p = 0.05).

Results

Physical properties results were material dependent. Physical properties of the GIC and RMGI products were inferior at 1 h compared to that at 24 h. Some improvement in selected physical properties were noted over time, but development processes were basically concluded by 24 h. A few materials demonstrated improved physical properties over the course of the evaluation.

Conclusions

Under the conditions of this study:

1. 1.

   GIC and RMGI physical property performance over time was material dependent;

2. 2.

   Polyalkenoate maturation processes are essentially complete by 24 h;

3. 3.

   Although differences in GIC physical properties were noted, the small magnitude of the divergences may render such to be unlikely of clinical significance;

4. 4.

   Modest increases in some GIC physical properties were noted especially flexural modulus and hardness, which lends support to reports of a maturing hydrogel matrix;

5. 5.

   Overall, GIC product physical properties were more stable than RMGI;

6. 6.

   A similar modulus reduction at 6 months for both RMGI and GIC produced may suggest a polyalkenoate matrix change; and

7. 7.

   Globally, RMGI products demonstrated higher values of flexure strength, flexural toughness, and fracture toughness than GIC materials.

Clinical relevance

As compared to RMGI materials, conventional glass ionomer restorative materials demonstrate more stability in physical properties.
