Rigidity of commonly used dental trauma splints

DENTAL TRAUMATOLOGY, Issue 3 2009
Christine Berthold
We evaluated the rigidity of various commonly used splints in vitro Material and Methods:, An acrylic resin model was used. The central incisors simulated injured teeth, with increased vertical and horizontal mobility. The lateral incisors and canines stimulated uninjured teeth. Tooth mobility was measured with the Periotest® device. Vertical and horizontal measurements were made before and after splinting, and the difference between values was defined as the splint effect. We evaluated 4 composite splints, 3 wire-composite splints, a titanium trauma splint, a titanium ring splint, a bracket splint, and 2 Schuchardt splints Results:, For all injured teeth and all splints, there was a significant splint effect for the vertical and horizontal dimensions (P < 0.05). For injured teeth, the composite splints produced the largest changes in vertical tooth mobility; wire-composite splints 1 and 2, using orthodontic wires, produced the smallest vertical splint effects. For uninjured teeth, the Schuchardt 1 splint and the bracket splint produced the largest splint effects; wire-composite splints 1 and 2 produced only a slight change in tooth mobility. Composite splints 2 and 3 produced the largest horizontal splint effects for injured teeth, and the 4 composite splints produced the largest horizontal splint effects for uninjured teeth. The most horizontally flexible splints were the titanium trauma splint and wire-composite splints 1 and 2. Conclusions:, According to the current guidelines and within the limits of an in vitro study, it can be stated that flexible or semirigid splints such as the titanium trauma splint and wire-composite splints 1 and 2 are appropriate for splinting teeth with dislocation injuries and root fractures, whereas rigid splints such as wire-composite splint 3 and the titanium ring splint can be used to treat alveolar process fractures.

An evaluation of the Periotest® method as a tool for monitoring tooth mobility in dental traumatology

DENTAL TRAUMATOLOGY, Issue 2 2010
Christine Berthold
The aims of this study were to determine normal Periotest® values in the vertical and horizontal dimensions of periodontally healthy teeth in individuals aged 20,35 years and investigate the reliability of Periotest® in terms of intra-series and inter-series reproducibility before and after applying a dental trauma splint in vivo. Materials and methods:, Periotest® values were measured in periodontally healthy dental students (n = 33; mean age 24.7 years) at reproducible measuring points in the vertical and horizontal dimensions, before and after splint insertion. Three readings were taken per series to observe the intra-series reproducibility; three series were measured to test inter-series reproducibility (Friedman-test; P , 0.001). Two different wire-composite splints, 0.45 mm Dentaflex and 0.8 × 1.8 Strengtheners, were inserted and the Periotest® values were measured. Results:, The median Periotest® values before splinting were: canines -2.5, lateral incisors -0.9, and central incisors 0.0 for the vertical dimension, and canines 1.1, lateral incisors 3.2, and central incisors 3.6 for the horizontal dimension. The intra-series and inter-series Periotest® values were highly reproducible. Conclusion:, The Periotest® method provides highly reproducible results. Focused on dental trauma, the method can be applied diagnostically during the splint and follow-up period and for evaluating splint rigidity. [source]

Rhabdomyosarcoma of the mandible in a 6-year-old boy

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2006
L. E. DAVIDSON
Summary., Introduction., Rhabdomyosarcoma is an aggressive malignant tumour composed of neoplastic mesenchymal cells that infiltrate surrounding tissue structures, making their precise site of origin unclear. Although rare, this is highly aggressive and the most common soft-tissue neoplasm of the head and neck in children. Regrettably by the time most cases are initially seen, the patients already have large tumours, due to rapid tumour growth and delayed medical consultation. Case Report., This report describes a 6-year-old presenting with just such symptoms of facial swelling and pain but elicitation of further information and findings, including tooth mobility of 3 days duration, led to prompt referral and early treatment of an embryonal rhabdomyosarcoma. Conclusion., General dental practitioners are frequently presented with a child with a swollen face and pain. Experience would suggest a dental abscess to be the most likely cause with treatment as appropriate. However, all swellings in children, should be thoroughly investigated and reviewed as particularly in this age group, tumour growth is rapid while early diagnosis allows successful treatment with multimodality therapy.

The periodontal abscess (I).

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 6 2000
Clinical, microbiological findings
Background/aims: Little information is available regarding the diagnosis and microbiology of periodontal abscesses. The aim of this descriptive clinical and microbiological study was to provide more information in order to help in the characterisation of the periodontal abscess associated to periodontitis. Method: 29 consecutive patients with a periodontal abscess were studied by the assessment of clinical variables, including both subjective (pain, edema, redness and swelling) and objective (bleeding on probing, suppuration, probing pocket depth, tooth mobility and cervical lymphadenopathy) parameters. Microbiological samples were taken for anaerobic microbiology and processed by means of culture. Systemic involvement was also studied through the analysis of blood and urine samples using conventional laboratory standards. Results: 62% of the abscesses affected untreated periodontitis patients, and 69% were associated with a molar tooth. More than 75% of the abscesses had moderate-severe scores related to edema, redness and swelling, and 90% of the patients reported pain. Bleeding occurred in all abscesses, while suppuration on sampling was detected in 66%. Mean associated pocket depth was 7.28 mm, and 79% of teeth presented some degree of mobility. Cervical lymphadenopathy was seen in 10% of patients, while elevated leucocyte counts were observed in 31.6%. The absolute number of neutrophils was elevated in 42% of the patients. High prevalences of putative periodontal pathogens were found, including Fusobacterium nucleatum, Peptostreptococcus micros, Porphyromonas gingivalis, Prevotella intermedia and Bacteroides forsythus. Conclusions: The periodontal abscess has clear clinical characteristics and is usually associated with severe periodontal destruction. This condition may cause systemic involvement and the lesion generally has a large bacterial mass with a high prevalence of well-recognised periodontal pathogens. [source]

Short-term clinical, microbiological efficacy of 2 systemic antibiotic regimes
Background/aims: The aim of this short-term open parallel longitudinal clinical study was to compare the clinical and microbiological efficacy of 2 different antibiotic regimes in the treatment of acute periodontal abscesses. Method: After patient selection, a clinical examination was carried out recording the following variables: pain, edema, redness, swelling, bleeding on probing, suppuration, tooth mobility, lymphadenopathy, and probing pocket depth. Microbiological samples were taken from the lesion and the patient was randomly assigned to one of two antibiotic regimes: azithromycin or amoxicillin/clavulanate. Clinical variables were recorded, and microbiological samples were taken, at 3,5 days, 10,12 days and 30 days. Additional mechanical treatment (debridement and scaling) was performed in the third visit (10,12 days). Blood and urine samples were collected at baseline and after 10,12 days. Microbiological samples were processed by anaerobic culturing, and isolated periodontal pathogens were tested for antibiotic susceptibility by means of the spiral gradient endpoint methodology. Results: 15 patients took azithromycin, and 14 amoxicillin/clavulanate. Subjective clinical variables demonstrated statistically significant improvements with both antibiotic regimes, which lasted for at least 1 month (p<0.01). Objective clinical variables also showed clear improvements, being statistically significant after 30 days with probing pocket depth in the azithromycin group (p<0.01). Microbiologically, short-term reductions were detected with both antibiotics, however fast recolonization occurred after the third visit. No significant differences were found between both treatment regimes. Antibiotic susceptibilities demonstrated no resistances for amoxicillin/clavulanate, while 2,3 strains of each studied pathogen were resistant to azithromycin. Conclusions: However, both antibiotic regimes were effective in the short-term treatment of periodontal abscesses in periodontitis patients. [source]

Langerhans cell histiocytosis: oral/periodontal involvement in adult patients

ORAL DISEASES, Issue 8 2009
S Annibali
Objective:, Langerhans cell histiocytosis (LCH) is a clonal proliferative multisystem disease. Although bone and mucosae have been classified as non-risk organs, their involvement may increase the risk of disease progression. Oral and periodontal lesions are burdened with a significant impairment of quality of life for associated signs, symptoms and loss of function. Most of information regards paediatric disease; the disease in adults has received limited attention. Subjects and Methods:, A total of 31 adult patients affected by immuno-histopathology confirmed LCH have been prospectively examined; attention was paid to the occurrence and characterization of oral lesions. Results:, Twelve patients developed oral lesions. Posterior regions of jawbones were always affected; the involvement of anterior regions was not constant. Unifocal oral involvement was significantly associated with multisystemic disease while multifocal lesions were associated with unisystemic disease. Oral disease presented with soft tissue ulcers (50% of cases), gingival bleeding (66.7%), pain (83.4%), periodontal damage (50%), tooth mobility (16.7%), non-healing extraction socket (8.3%); 41.6% of patients complained of negative outcomes on quality of life. Oral lesions were easily handled with local measures. Conclusions:, Posterior regions require attention; single oral lesions may be part of multisystemic disease; oral and periodontal lesions may be early signs of disease reactivation. [source]
