Article
Apical peri-implantitis is often diagnosed by clinical findings such as pain, redness, tenderness, swelling, and sometimes the presence of a fistulous tract. There are few theories about how such a lesion occurs. Hence, the current clinical treatment protocols are scanty. The aim of this report was to evaluate and confer a more extended surgical pr...
Article
The aim of this study was to retrospectively evaluate iatrogenic dental root damage, caused by two different techniques that utilized bone anchor screws, for intermaxillary fixation (IMF) in orofacial trauma. The techniques used included either predrilled or drill-free bone anchor screws. A total of 123 patients who required IMF were evaluated (97...
Article
Background: NEOSS® (Neoss Ltd., Harrogate, UK) dental implant system was introduced on the clinical arena in 2003. It is important that novel implant systems are systematically evaluated in a multicenter setting. Purpose: The aim of this study was to follow a large number of consecutively treated patients, with NEOSS dental implant system, both cli...
Article
Objectives Crohn’s disease (CD) is associated with reduced bone mineral density. The main objective of the present study was to assess the mandibular trabecular bone quality and to compare our findings with those among sex- and age-matched controls. Furthermore, background variables known to be significant for bone density were compared. Materials...
Article
Bone augmentation before treatment with endosseous implants is a common procedure for rehabilitation of the edentulous jaw. Both machined and surface modified implants have been used in one-stage and two-stage surgery protocols with varying results and survival rates. The influence of surface modification on the integration of implants has been doc...

Objective: Development of a new questionnaire, Oral Health-Related Quality of Life - Neurosensory Disturbances after Orthognathic Surgery (OHRQL-NDO), designed to measure the effects of neurosensory disturbance (NSD) on patients' oral health-related quality of life (OHRQL) and to evaluate reliability and validity of this questionnaire. Materials...

Objective The relationship between oral health and Crohn’s disease is uncertain. Previous studies have yielded contradictory results, reflecting perhaps the different phenotypes of the disease. The aim of the present study was to describe and analyse the dental status of a group of patients with Crohn’s disease (CD), considering the positions of th...
Chapter
Dental implant is one of the most rapidly developed techniques in dentistry with good predictability, functionality for the replacement of missing teeth. The era of modern dental implantation began about 50-years ago for use in replaceing missing teeth. The treatment procedure is safe, and has high long-term implant survival rates for all jaw situ...

Background Studies are inconsistent whether people with Crohn’s disease (CD) have an increased fracture risk. Methods Forty-nine CD and 49 controls participated. All 98 completed a health questionnaire. A score with the fracture assessment tool FRAX >15% was considered risk factor for fracture. Results Mean FRAX-score for 49 CD was 10.1±10.3% and...

The objective of this study was to evaluate implant survival in reconstructed bone after the use of a synthetic bone substitute material (Calcium Sulphate). Clinical, radiological and histological parameters were studied in 25 patients. Unilateral and bilateral sinus augmentation was performed. An 80% + 20% mixed alpha hemihydrate Calcium Sulphate...
Article
Objective To investigate the incidence and reasons for titanium fixation plate removal following orthognathic surgery, identify risk factors predisposing removal and to explore if discomfort was reduced postoperatively. Methods Medical records of 404 consecutive patients were retrospectively reviewed. All patients received a questionnaire for foll...

Orthognathic surgery is mostly performed to correct developmental or acquired oral and maxillofacial skeletal deformities (OMSDs). During the past three decades, significant advances in surgical osteotomy techniques and instrumentation have been developed and carried out in orthognathic surgery. However, the basic surgical principles have more or l...

Aim: Surgical corrections of dentofacial deformities have both physical and psychological impact on quality of life (QoL). The objectives of the present study were to evaluate the impact of oral health related problems on QoL before and after a combination of orthodontic treatment and orthognathic surgery. Additionally, the study aimed to identify...
Article
A randomized, prospective, controlled trial was conducted to determine the efficacy of single and repeated betamethasone doses on facial oedema, pain, and neurosensory disturbances after bilateral sagittal split osteotomy. Thirty-seven patients (mean age 23.62 years, range 17–62 years) with either mandibular prognathism or retrognathism were enroll...
Article
Monochromatic light has been used in many studies and indicated that phototherapy might be effective in the treatment of pain relief. The aim of this investigation was to evaluate the efficacy of monochromatic light phototherapy on patients who had undergone impacted third molar surgery. Sixty adult patients were included in the study. The patients...
Article
Mandibular advancement was studied in 32 patients with mandibular retrognathia in whom the only intervention was in the mandible. Fifteen patients were treated with fixation by lag screws and 17 with monocortical miniplates. Lateral radiographs were taken preoperatively, postoperatively, 2 months postoperatively, and 1.5 years postoperatively, and...
Article
Background: The routine use of antibiotics in oral implant treatment seems to be widespread. The pre-or postoperative use of antibiotics in conjunction with implant surgery and its correlation with failure and success rates are poorly documented in the literature. The debate regarding overprescription of antibiotics raises the need for a critical e...
Article
The rich blood supply enjoyed by facial tissue means that the risk for necrosis caused by poor vascularity is reduced under normal conditions. Severe trauma to the face may, however, result in fractures with a poor vascular supply of the respective segment. This may subsequently lead to the loss of that tissue segment due to necrosis. Smaller bone...

Article
The antimicrobial effect of birch toothpicks impregnated with 4% NaF, 8% SnF2, or 2% chlorhexidine was studied both in vitro and in vivo. A non-impregnated toothpick served as a control. In vitro, suspensions of Streptococcus mutans were exposed to the various toothpicks for 20 min and then cultured on blood agar. The results of this susceptibility...
Article
The aim of this investigation was to study the effect of the interproximal use of fluoride (F)-impregnated and non-impregnated birch toothpicks on the degree of de- and remineralization of enamel and dentine in situ. Ten volunteers with complete dentures in the upper jaw participated. Each subject had four specimens: (1) sound enamel, (2) demineral...
Article
The aim of this thesis was to evaluate the wooden toothpick as a vehicle for the delivery of fluoride to the approximal area. After two minutes use in vivo, the release of fluoride from the pointed section of a toothpick impregnated in 4% NaF was estimated to 0.15 mg. Toothpicks produced similar or somewhat higher fluoride concentrations in the app...
Article
The aim of this work was to study the fluoride (F) concentration in the approximal area after using toothpicks and other F-containing products. The exposure time was standardised to 2 min. 24 subjects participated, divided into 4 groups, with 6 individuals per group. In 3 of the groups, the following 4 products were compared: (1) a toothpick impreg...
Article
Birch and lime toothpicks were impregnated in a 4% sodium fluoride (NaF) solution for different periods of time, viz. 30 s, 30 min and 3 d. After impregnation for 30 min, an average of 4.1 mg NaF per birch toothpick was taken up. The corresponding value for lime toothpicks was 5.1 mg. About 60% of the fluoride (F) was released within 1 h in vitro w...
Article
Fluoridated toothpicks (John O. Butler Co.), containing an average of 0.80 mg F as NaF, demonstrated a quick F release in vitro after 1 min immersion in distilled water (0.13 mg; 16%). Continued F release was found after 5 (0.22 mg; 28%) and 60 min (0.35 mg; 44%) and 24 hr (0.55 mg; 69%). In addition, F concentrations were measured in whole saliva...
