Purpose: We present our experience using modified Hyrax devices for treating transverse deficiencies of the maxilla in adult patients with periodontal pathology or insufficient tooth anchorage. The surgical technique, clinical indications, and results are discussed.
Materials And Methods: Eight adult patients (6 females, 2 males) requiring maxillary expansion were studied prospectively between July 2002 and July 2007. All the patients had periodontal pathology or insufficient tooth anchorage preventing the use of conventional Hyrax devices. Patients underwent surgically assisted rapid maxillary expansion with the use of custom-made modified Hyrax devices (bone-borne or tooth-bone-borne devices). Patients received preoperatively (T1), at the end of distraction (T2), at removal of the expansion device (T3), and 12 months after surgery (T4) lateral and posterior anterior cephalograms and study models to measure the width of the anterior and posterior dental arches with a digital sliding calliper.
Results: Mean age was 28.5 years (range, 18-45 years). A significant widening of the anterior (6.3 +/- 1.6 mm) and posterior (7.1 +/- 1.2 mm) dental arches was demonstrated. No significant differences were found when comparing T3 with T4 measures. No significant complications were found.
Conclusion: The results indicated that maxillary expansion with custom-made devices in adults was an easy, affordable, predictable and stable technique without significant complications in patients who suffer periodontal pathology or patients without enough dental support.

Plasma, which was coined by Irving Langmuir in 1928, is the fourth physical state after the solid/liquid/gas phases. Low-temperature plasma (LTP) is a contradictory condition that involves high energy with free radicals at near-body temperatures and was developed through engineering in the 1990's. Research on LTP in engineering and medical fields has rapidly developed since the 2000's.

While histone deacetylation by histone deacetylases (HDACs) is well established, the role of specific HDACs in modulating non-histone protein PTMs, particularly in an infectious context, is poorly understood. Here, we reveal a pivotal role for HDAC6 in orchestrating periodontal inflammation through its dual regulatory effects on FoxO1 acetylation and phosphorylation.

Periodontal ligament fibroblasts (PDLFs) play a crucial role in the etiology of periodontitis and periodontal tissue regeneration. In healthy periodontal tissues, PDLFs maintain the homeostasis of periodontal soft and hard tissues as well as the local immune microenvironment. PDLFs also have the potential for multidirectional transdifferentiation and are involved in periodontal tissue regeneration.

Introduction: Cases involving invasive cervical root resorption (ICRR) in oncological patients are rare, in addition, follow-up of these patients has not yet been reported in the literature.
Objective: This study aims to present a literature review and report a case of denosumab as a possible cause of ICRR in a patient with breast cancer with 2 years of follow-up.
Case Report: A 39-year-old female with a history of luminal breast cancer was treated with denosumab semiannually for osteopenia with discontinuation 1 year ago.

Background: Oral health represents a public health problem due to its remarkable social impact and medical costs. Crenotherapy with sulfur water is shown to be a complementary, less toxic, and traumatizing therapy, but the number of studies that evaluate the effect of natural mineral waters effect on oral health are scarce. The aim of this pilot study is to evaluate the impact of thermal water therapy on the oral health of the participants, assessing parameters such as plaque index, gingival bleeding index and periodontal probing depth as well on the perception of symptoms of oral mucosa diseases (OMD).
