营养状况综合评分法在口腔颌面恶性肿瘤患者的应用

本文采用营养状况综合评分法(GNS)对127例口腔颌面部恶性肿瘤患者进行了营养评价,结果36.2％(46/127)营养不良,63.8％(81/127)营养良好。比较这两个营养组病人的实验室营养指标值差异,发现白蛋白、运铁蛋白和肌酐身高指数差别有显著性(P<0.05),说明GNS与用于营养评价的实验室指标有良好的一致性。营养不良组病人术后并发症发生率(48.3％)显著高于良好组(19.4％)(X~2=6.637,P<0.01),提示GNS可用于估价口腔颌面恶性肿瘤的手术预后。     

Quality of reporting masticatory muscle electromyography in 2004: a systematic review

This study evaluated the quality of reporting electromyography in studies evaluating the masticatory muscles published during 2004. Several electronic databases were searched. Abstracts and later articles were selected by a consensus from the five reviewers. An adaptation of the methodological checklist published by the International Society of Electrophysiology and Kinesiology (ISEK) was used. The following information regarding electrodes was reported on the 35 finally selected articles: location (94.3%), interelectrode distance (48.6%), and material (42.9%); detection and amplification: amplification type (54.3%), gain (25.7%), low high pass filters (60%) and cut-off frequencies (60%); electromyography (EMG) processing: sampling rate (74.2%), rectification (46.6%), root-mean square (RMS) (39.2%); number of bits and model of A/D card (17.1%); and normalization procedure (40%). Reasons for the poor reporting are discussed. Because of the general poor quality of reporting of the analysed studies, findings of studies using surface electromyography of masticatory muscles should be interpreted with caution.     

Microbiological composition associated with interleukin-1 gene polymorphism in subjects undergoing supportive periodontal therapy

BACKGROUND: Interleukin-1 gene polymorphism (IL-1 gene) has been associated with periodontitis. The present study examined the subgingival microbiota by IL-1 gene status in subjects undergoing supportive periodontal therapy (SPT). METHODS: A total of 151 subjects with known IL-1 gene status (IL-1A +4845/IL-1B -3954) (IL-1 gene) were included in this study. Clinical data and subgingival plaque samples (40 taxa) were collected. These taxa were determined by the checkerboard DNA-DNA hybridization method. RESULTS: Gender, smoking habits (n-par tests), age, and clinical periodontal conditions did not differ by IL-1 gene status. IL-1 gene-negative subjects had a higher total bacterial load (mean difference, 480.4 x 10(5); 95% confidence interval [CI], 77 to 884 x 10(5); P <0.02). The levels of Actinobacillus actinomycetemcomitans (mean difference, 30.7 x 10(5); 95% CI, 2.2 to 59.5 x 10(5); P <0.05), Eubacterium nodatum (mean difference, 4.2 x 10(5); 95% CI, 0.6 to 7.8 x 10(5); P <0.02), Porphyromonas gingivalis (mean difference, 17.9 x 10(5); 95% CI, 1.2 to 34.5 x 10(5); P <0.05), and Streptococcus anginosus (mean difference, 4.0 x 10(5); 95% CI, 0.2 to 7.2 x 10(5); P <0.05) were higher in IL-1 gene-negative subjects, an observation specifically found at sites with probing depths <5.0 mm. CONCLUSIONS: Bleeding on probing did not differ by IL gene status, reflecting clinical SPT efficacy. IL-1 gene-negative subjects had higher levels of periodontal pathogens. This may suggest that among subjects undergoing SPT, a lower bacterial load is required in IL-1 gene-positive subjects to develop the same level of periodontitis as in IL-1 gene-negative subjects.

Longitudinal craniofacial growth patterns in patients with orofacial clefts: geometric morphometrics.

OBJECTIVE: To demonstrate craniofacial developmental patterns in repaired cleft lip and cleft palate (CLP). DESIGN: Retrospective, longitudinal. SETTING: Center for Craniofacial Disorders, San Juan, Puerto Rico. SAMPLE: Males aged 9 to 17 years: 13 noncleft (NC) Class I occlusion (NCC1); 13 NC Class III malocclusion (NCC3); 12 CLP Class I occlusion (CLPC1); and 15 CLP Class III malocclusion (CLPC3). MAIN OUTCOME MEASURES: Form changes (ages 10, 13, and 16 years), using finite-element scaling analysis. RESULTS: NCC1, 10 to 13 interval: 30% size increase in upper midface (p <.05), mental region (p <.01), mandibular body (p <.05); 13 to 16 interval: 10% to 35% size increase in bimaxillary region and ramus (p <.01). NCC3, 10 to 13 interval: 10% to 40% size increase in posterior cranial base, upper midface, and mandible (p <.05); 13 to 16 interval: 10% to 30% size increase in bimaxillary region (p <.01), especially ramus. CLPC1, 10 to 13 interval: 10% to 15% size increase in posterior cranial base (p <.01), midface (p <.05), and mandibular ramus (p <.05); 13 to 16 interval: 8% to 20% size increase in upper midface (p <.01), lower midface (p <.05), and mandible (p <.05). CLPC3, 10 to 13 interval: no significant changes; 13 to 16 interval: upper midface and cranial base show nonsignificant size decreases, but ramus showed size increase. CONCLUSIONS: Noncleft and CLP Class 1 occlusion groups show similar craniofacial growth patterns. Noncleft Class III groups show excessive cranial and mandibular growth. Class III malocclusion in CLP patients is associated with clinically deficient craniomaxillary growth. Growth guidance may be indicated in children with CLP with unfavorable craniofacial growth patterns.     

Active white enamel lesion: a case-control study

PURPOSE: To assess the risk factors involved for active white enamel lesion in public schoolchildren, aged 7 to 12 years, in Natal, Brazil, using a case-control study. MATERIALS AND METHODS: A total of 273 cases of active white enamel lesion and 325 controls (lesion-free) were matched by age, gender and school. The independent variables were: age; gender; visible plaque index (VPI); gingival bleeding index (GBI); decayed, missing and filled surfaces (DMFS); decayed, extracted or filled surfaces (dmfs); DMFS-dmfs; and the number of carious surfaces. RESULTS: There was no statistical significance for age (p = 0.57), gender (p = 0.428) and dmfs (p = 0.06). Univariate analysis revealed an increased risk of developing active white enamel lesions in individuals with high VPI (OR = 15.5, CI 95% 10.35-23.2), GBI (OR = 2.86, CI 95% 2.05-3.99), DMFS (OR = 18.91, CI 95% 12.51-28.59), DMFS-dmfs (OR 10.22, CI 95% 7.01-14.91) and number of carious surfaces (OR = 5.47, CI 95% 3.85-7.78). Logistic regression analysis identified that GBI (OR = 2.14, CI 95% 1.41-3.25) and DMFS (OR = 17.3, CI 95% 11.39-26.27) were independent risk factors for active white lesions. CONCLUSIONS: The results reaffirm the importance of mechanically controlling biofilm to prevent caries development in its initial stage (white lesion).     

Long-term physical inactivity and oral health in Finnish adults with intellectual disability

Physical inactivity is prevalent among patients with intellectual disability. Because little is known about the oral effects of poor mobility, we reviewed the medical and dental charts of institutionalized dentate patients (n = 214; 40.2 years +/- 12.1) of the Special Welfare District of Southwestern Finland. The number of decayed, missing, and filled teeth (DMFT), the number of retained teeth, dental treatment visits, and the type of the first treatment visit were recorded. Physical activity was good in 55% and severely reduced or completely absent in 45% of the patients. The degree of intellectual disability was mild or moderate in 40% and severe or profound in 60% of the patients. The walking patients weighed more (64.3 (19.6) versus 44.4 (14.4) kg; P< 0.001), had fewer secondary diagnoses (1.4 (1.3) versus 2.2 (1.4); P< 0.001), fewer daily medications (4.0 (2.1) versus 4.8 (2.4); P< 0.02), higher DMFT scores (18.5 (8.2) versus 14.8 (9.2); P < 0.05), and more dental treatment visits (2.7 (2.4) versus 2.0 (1.3); P< 0.03) than patients with poor physical activity. Periodontal treatment given as the primary type of dental care was more common among subjects with poor mobility than among those with good motor activity (P < 0.002). Poor physical activity was related to better dental health, higher need for periodontal therapy, and fewer dental visits than in patients with good motor activity.     

Influence of endodontic irrigants on bond strength of a self-etching adhesive

The aim of this in vitro study was to evaluate the bond strength of a self-etching adhesive system to dentine irrigated with sodium hypochlorite (NaOCl), chlorhexidine solution (CX) and ethylene diamine tetra acetic acid (EDTA) by microtensile testing. Sixty human third molars were sectioned 3 mm below the occlusal level and then randomly divided into six groups: G1(control), without irrigant solution; G2, 1% NaOCl; G3, 1% NaOCl followed by the application of 17% EDTA; G4, 2% CX; G5, 2% CX followed by the application of 17% EDTA and G6, 17% EDTA. The specimens received the self-etching adhesive system were restored with composite resin, then sectioned and trimmed to obtain four hourglass-shaped slabs from each tooth. The specimens were submitted to the microtensile test in a Universal Testing Machine at a crosshead speed of 0.5 mm min(-1) until fracture. The results were submitted to statistical analysis by anova /Newman-Keuls. The means and standard deviations (MPa) were: G1, 26.88 (±3.81); G2, 19.08 (±3.89); G3, 18.16 (±2.21); G4, 18.14 (±4.32); G5, 34.30 (±3.32); G6, 13.61 (±1.21). It was concluded that the application of 2% CX followed by the application of 17% EDTA resulted in increasing the bond strength of the self-etching adhesive system to dentine, when compared with the results obtained for the other tested groups.     

Microbiological examination of infected dental root canals

OBJECTIVES: The aim of this study was to investigate the root canal microbiota of primary and secondary root-infected canals and the association of constituent species with specific endodontic signs and symptoms. METHODS: Microbial samples were taken from 60 root canals, 41 with necrotic pulp tissues (primary infection) and 19 with failed endodontic treatment (secondary infection). Strict anaerobic techniques were used for serial dilution, plating, incubation and identification. RESULTS: A total of 224 cultivable isolates were recovered belonging to 56 different bacterial species. Individual root canals yielded a maximum of 10 bacterial species. Of the bacterial isolates, 70% were either strict anaerobes or microphilic. The anaerobes most frequently isolated were: Peptostreptococcus micros (35%), Fusobacterium necrophorum (23.3%), Fusobacterium nucleatum (11.7%), Prevotella intermedia/nigrescens (16.7%), Porphyromonas gingivalis (6.7%) and Porphyromonas endodontalis (5%). The root canal microflora of untreated teeth with apical periodontitis was found to be mixed, comprising gram-negative and gram-positive and mostly anaerobic microorganisms and usually containing more than 3 species per canal. On the other hand, facultative anaerobic and gram-positive bacteria predominated in canals with failed endodontic treatment, which harbored 1-2 species per canal. Suggested relationships were found between anaerobes, especially gram-negatives, and the presence or history of pain, tenderness to percussion and swelling (P<0.05). In particular, associations were found between: a) pain (n=29) and P. micros (P<0.01), P. intermedia/nigrescens and Eubacterium spp. (both P<0.05); b) history of pain (n=31) and P. micros (P<0.01) Porphyromonas and Fusobacterium spp. (P<0.05); c) tenderness to percussion (n=29) and Porphyromonas spp. (P<0.01), Peptostreptococcus and Fusobacterium spp. (P<0.001); d) swelling (n=20) and Peptostreptococcus spp. (P<0.01), Porphyromonas and Enterococcus spp. (P<0.05); e) wet canals (n=33) and Porphyromonas and Fusobacterium spp. (P<0.05); f) purulent exudate (n=20) and Porphyromonas, Peptostreptococcus and Fusobacterium spp. (P<0.05); previous endodontic treatment and Enterococcus faecalis, Streptococcus spp., P. micros, F. necrophorum (P<0.05). CONCLUSIONS: Our findings indicate potential complex interactions of species resulting in characteristic clinical pictures which cannot be achieved by individual species alone. They also indicate that the microbiota of primary infected canals with apical periodontitis differs in number and in species from the secondary infected canals by using the culture technique.
