Abstract:

Statement of the problem: Temporo-Mandibular joint Disorder (TMD) is a widely researched disease in the literature since it has a high prevalence and is often associated with chronic pain and limited function of the Temporo-Mandibular Joint (TMJ).

Osteoarthritis (OA) is considered a whole joint disease with deterioration and loss of the cartilage, changes in bone structures and subchondral and synovial inflammation with reactive oxygen species formation producing the induction of neuropeptides and inflammatory cytokines.

TMJ Visco-Supplementation (VS) is a minimally invasive procedure that consists of an intra-articular injection of sodium Hyaluronate (HA) into the joint compartments. HA is an efficient therapy to promote articular homeostasis and analgesia by stimulating type B synoviocytes to produce additional synovial liquid, with improvements on the lubrication, rheological properties of the synovial liquid, absorption of loads and stimulation of chondrocyte proliferation in fibrocartilage.

Our group did a study to assess a VS protocol, with Cone-Beam Computed Tomography (CBCT) and Ultra-Sonography (US). It was a 3 stages study. First stage: Check the correspondence between the facial points and the osseous components of the TMJ using CBCT. Second stage: Injection of the upper and lower compartments of 20 TMJs of frozen cadavers with colored liquids and dissecting the specimens, Third stage: VS in 20 TMJs with verification by ultrasonography. The proposed protocol was effective for accessing the upper and lower compartments of the TMJ. The evaluated protocol proved to be accurate, safe and clinically reproducible for the assessment of upper and lower compartments.

Superior and inferior joint space injections of Hyaluronic Acid (HA) are effective methods for the treatment of temporomandibular without reduction (ADDWR) in association with TMJ OA. The injection of HA within the inferior joint space appears to result in better condylar reparative remodeling and improvement in jaw function

Abstract:

Transplantation of teeth has a very long history, what started as intentional replantation with the pharaohs became autotransplantation in the 1950 in Denmark and Norway.

In 2004 we started to transplant premolars in Rotterdam. We evaluated our treatment results, as a team and came to a successful guideline for this procedure. This guideline modified during the first 17 years of transplantation. The premolars we transplanted to the posterior region during this period were evaluated to establish the guideline to maximize the success.

Indication, diagnosis and treatment planning will be discussed illustrated by a case and the results of our recent study.

Abstract:

Dentistry has entered an exciting era of high technology. Lasers provide new powerful tools that is characterized by a bloodless field and applied in most branches of dentistry. There are many types of lasers, such as diode laser, Nd: YAG, Erbium lasers and CO2 lasers. Each laser type has its own unique features, advantages and disadvantages. While one laser may be suitable for some procedures, it will be unsuitable for others, so it is important for the dentist to have back ground  information about this technology and its uses in dentistry.

Objectives: To compare the effect of intravenous dexamethasone and intravenous acetaminophen (Apotel) on oral pain, agitation, sore throat, nausea/vomiting and recovery time after dental rehabilitation under general anesthesia in children.

Materials and methods: A total of 60 ASA I, II children in need of dental treatment under general anesthesia in the age range of 2-6 years were included in this prospective double-blinded clinical trial study. All children received 0.5 mg/kg oral midazolam 15 minutes before the intervention. Standard anesthesia techniques including inhalation induction with sevoflurane, followed by venipuncture and intravenous fentanyl l µg/kg and atracurium 0.5 mg/kg were used. Patients were randomly divided into two groups. After induction of anesthesia, the first group received 0.5 mg/kg intravenous dexamethasone and the second group received 15 mg/kg intravenous acetaminophen.

Results: The median recovery time in the Apotel group was significantly shorter (90 vs. 115; p-value<0.001). However, the dexamethasone group showed significantly less agitation (9 vs. 12; p-value=0.005). There was no difference between the two groups in terms of oral pain and sore throat. Dexamethasone group showed less nausea/vomiting during recovery (p-value=0.005) but in 24-hour follow-up, nausea/vomiting showed no significant difference between the two groups (p-value=0.23).

Conclusion: Dexamethasone is a more appropriate intervention compared to Apotel despite the longer recovery time, due to less agitation and nausea and vomiting during recovery. However, it has no advantage over Apotel in terms of reducing mouth pain and sore throat.

Background and objectives: One of the new methods in the treatment of early caries lesions is the use of low viscose resins as an infiltrant substance inside the lesion's porosities. This study aimed to clinically and radio graphically assesses the efficiency of application of resin infiltration method to prevent proximal enamel caries progression in primary posterior teeth.

Materials and methods: This study was conducted on the teeth of 32 children aged 5-10 years who referred to the pediatric dental department of Tehran University of Medical Science. Each child had at least one pair of proximal non cavitated enamel caries in their posterior primary teeth. In each child, one lesion was treated with resin infiltration and another lesion was considered as control group with routine dental hygiene. (Three times a day dental flossing and tooth brushing). After 6 months, all lesions were examined clinically and radio graphically in terms of caries progress. The two groups were compared by the Fisher’s exact test.

Results: In the resin infiltrant group, there was no progress in any of the enamel lesions after 6 months and all 16 surfaces (100%) showed cessation of caries. But in the control group, two of the initial lesions progressed and became cavitated. However these results in two groups were not significantly different (P=0.242).

Conclusion: Resin infiltrant technique is effective to stop the progression of proximal enamel caries of primary molars; since none of the carious lesions progressed within 6 month of follow up.
