RESUMEN
OBJECTIVE: To evaluate the outcomes of Secondary Alveolar Bone Grafting (SABG) in patients treated either in daycare or with multiple day hospitalization (MDH) in relation to costs and complication rates. DESIGN: Retrospective comparative cohort study. SETTING: The data was collected from two settings: Postoperative daycare or MDH after oral cleft surgery in an Academic Medical Center in The Netherlands. PATIENTS: Data of 137 patients with unilateral Cleft lip, alveolus, and palate (CLAP) treated between 2006-2018 were evaluated. Registered clinical variables: age, gender, cleft subtype, bone donor site, type of hospitalization, length of stay, additional surgery, complications, surgeons, and costs. INTERVENTIONS: Closure of the alveolar cleft with/without closure of the anterior palate. MAIN OUTCOME MEASURES: Univariate analyses. RESULTS: Of the 137 patients, 46.7% were treated in MDH, and 53.3% in daycare. Total costs for daycare were significantly lower (P < .001). All patients treated in daycare received mandibular symphysis bone, whereas in MDH, 46.9% received iliac crest bone instead. Bone donor site was associated with postoperative care type. Complication rates were slightly but not significantly higher in daycare (26%) vs. MDH (14.1%) (P = .09). Most were Grade I (minor) according to Clavien Dindo classification. CONCLUSIONS: Daycare after alveolar cleft surgery is about as safe as MDH, but significantly cheaper.
RESUMEN
The aim of this study was to examine the potential relationship between the occurrence of orthodontic root resorption and presence of dental anomalies such as tooth agenesis and pipette-shaped roots. Dental anomalies and root resorption were assessed on dental panoramic tomographs (DPT) of 88 subjects, 27 males and 61 females, mean age 28.4 (SD = 11.3 years), selected from orthodontic patients on the basis of the following exclusion criteria: previous fixed appliance treatment, bad quality of the DPTs and no visibility of the periodontal ligament of every tooth, and younger than 15 years of age at the onset of treatment with fixed edgewise appliance lasting at least 18 months. A pipette-shaped root was identified as defined by a drawing. Tooth agenesis was assessed on DPTs and from subjects' dental history. Root resorption was calculated as the difference between the root length before and after treatment, with and without a correction factor (crown length post-treatment/crown length pre-treatment). If one of the four upper incisors showed root resorption of ≥2.3 mm with both formulas, the patient was scored as having root resorption. Chi-square tests indicated that there was no relationship between orthodontic root resorption and agenesis (P = 0.885) nor between orthodontic root resorption and pipette-shaped roots (P = 0.800). There was no relationship between having one of the anomalies and root resorption either (P = 0.750). In the present study, it was not possible to confirm on DPTs a relationship between orthodontic root resorption and dental anomalies, such as agenesis and pipette-shaped roots.

The aim of the present study is to examine all cases of intraosseous benign ameloblastomas treated between 1970 and 2010 in a single institution and to look for a possible correlation between the histopathological aspects and the demographical and clinical parameters, as well as the treatment outcome. The data of a total number of 44 patients were retrieved from the records. Nine patients were excluded because of doubt about the correct diagnosis (8 patients) or because of an extra-osseous presentation (1 patient). No statistically significant differences were found between the histopathological (sub)types of ameloblastomas and the demographical and clinical parameters, nor between the histopathological (sub)types and treatment outcome. Of the 28 patients treated by enucleation, in 17 patients one or more recurrences occurred, with no significant predilection for any histopathological (sub)type, including the unicystic type. There were no significant differences in the recurrence rate after enucleation in patients below and above the age of 20 years either. In six out of 17 patients with a recurrence, the recurrent lesion showed a different histopathological subtype than was encountered in the primary. In two cases a change from solid/multicystic to desmoplastic ameloblastomas was noticed. In conclusion, the current histopathological classification of benign intraosseous ameloblastoma does not seem to have clinical relevance with the possible exception of the luminal unicystic ameloblastoma that has been removed in toto, unfragmented. Since no primary desmoplastic ameloblastomas were encountered in the present study no further comments can be made on this apparently rare entity.

The presence of dental anomalies has been rated radiographically in a number of studies. However, since the reliability of the assessment of these anomalies has rarely been investigated, the aim of this study was to examine inter- and intraexaminer agreement in identifying morphological dental anomalies, such as tooth agenesis, dilacerated, pipette-shaped, blunt, pointed, and short roots. Pre-treatment panoramic radiographs of 40 patients (13 males and 27 females; mean age 27.7 ± 10.8 years) treated between 1983 and 2008 were selected. Four examiners independently assessed the radiographs twice. For a dilacerated root and agenesis, a definition was given. For pipette-shaped, blunt, or pointed roots, a drawing was shown, and for a short root, a ratio was used to identify the anomaly. Intraexaminer agreement of the assessments of the dental anomalies was presented by Cohen's Kappa and varied between -0.01 for short roots and 1.00 for agenesis. With respect to short roots, three of the examiners did not rate them to be present on at least one measurement occasion. This implies that intraexaminer agreement could not be calculated for these three examiners. Interexaminer agreement for dilacerated roots varied between 0.14 and 0.50, for pipette-shaped roots between -0.01 and 0.33, for blunt roots between 0.05 and 0.32, and for pointed roots between 0.17 and 0.37. All values for agenesis were 1.00. It can be concluded that assessing agenesis on panoramic radiographs is reliable. Rating the presence of dilacerated, pipette-shaped, blunt, pointed, and short roots on panoramic radiographs, however, does not result in a reliable assessment.

OBJECTIVES: The aims were: 1) to identify the guidelines available for management of dental invasive procedures in patients on antithrombotic drugs; 2) to assess their quality with the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument; and 3) to summarize their conclusions and recommendations. STUDY DESIGN: Systematic literature search for guidelines in several electronic databases. Retrieved guidelines were evaluated with the AGREE instrument for quality assessment. RESULTS: The systematic search yielded 93 results, of which only 4 were evidence-based practice guidelines. Two of these guidelines could be recommended for clinical use on the basis of the AGREE instrument. These 2 guidelines drew 68 conclusions from the existing literature and provided 58 recommendations. CONCLUSIONS: Two evidence-based clinical practice guidelines, satisfactorily fulfilling the criteria of the AGREE instrument and both published in 2007, advise to not routinely discontinue antiplatelet and anticoagulation medication before dental surgery. The majority of the recommendations, however, were not sufficiently linked to levels of evidence.

OBJECTIVE: Comparison of craniofacial morphology in bilateral cleft lip and palate patients to that of a noncleft control group at the age of 15 years. DESIGN: A cross-sectional study of cephalometric data. SUBJECTS AND METHODS: Cephalometric records of 41 consecutive patients (32 boys and 9 girls) with nonsyndromic complete bilateral cleft lip and palate born between 1973 and 1987. The patients were treated by the cleft teams of the Erasmus Medical Centre in Rotterdam and the VU University Amsterdam. The control group of normal Dutch subjects was followed in the Nijmegen Growth Study. From this population, mean cephalometric data were used. Differences in cephalometric measurements and other variables were calculated between the bilateral cleft lip and palate group and the control group. RESULTS: Independent-sample t tests indicated that there was a statistically significant difference between the mean of the cephalometric values of the bilateral cleft lip and palate patients and the control group with respect to all cephalometric variables. Pearson correlation coefficients calculated between angle ANB and the number of operators, number of surgical procedures before 15 years of age, and the year of birth were not significant. CONCLUSIONS: Bilateral cleft lip and palate patients treated in the Amsterdam and Rotterdam cleft centers differed significantly from the control group in all measurements. A Class III development due to a less forward positioned maxilla was observed. The vertical measurements indicated a more divergent growth pattern in bilateral cleft lip and palate patients (Ans-Me/N-Me, GoGn-SN, and SN-FFH).

To understand the development of dental anxiety better and to identify those at increased risk of developing dental anxiety, the Level of Exposure-Dental Experiences Questionnaire (LOE-DEQ) was developed. The aim of the current study was to determine the psychometric properties (i.e. factor structure, reliability, and validity) of the LOE-DEQ and to determine its suitability as an additional screening instrument for dentally anxious patients. Five different samples were used: (i) highly dentally anxious patients (n = 119); (ii) general dental patients (n = 480); (iii) students (n = 186); (iv) psychiatric outpatients (n = 17); and (v) oral surgery patients (n = 34). Results of the factor analysis revealed a four-factor solution. The LOE-DEQ has sufficient internal consistency (Cronbach's alpha values ranging from 0.69 to 0.85) and satisfactory test-retest reliability (intraclass correlation coefficient = 0.78). The results further suggest that this instrument has adequate discriminant, concurrent, and predictive validity. It is concluded that the LOE-DEQ is a useful tool for assessing patients' background in terms of previous exposure to distressing dental events, which is considered a vulnerability factor in the development of dental anxiety.

OBJECTIVE: The aim of this study was to investigate whether Dutch children with proven coeliac disease show specific dental enamel defects, and to asses whether children with the same gastrointestinal complaints, but proved no-coeliac disease, lack these specific dental enamel defects. MATERIALS AND METHODS: Eighty-one children (53 coeliac patients and 28 control subjects) were examined during the period 2003-2004 in the Oral Surgery Outpatient Clinic of the Academic Medical Centre in Amsterdam. RESULT: Twenty-nine (55%) coeliac patients had enamel defects against 5 (18%) control subjects. In the coeliac disease group, the enamel defects were diagnosed as specific in 20 (38%) children, compared with 1 (4%) in the control group. Statistical analysis showed significantly more specific enamel defects in children with coeliac disease than in children in the control group (chi(2) = 12.62, d.f. = 2, P = 0.002). CONCLUSION: This study showed significantly more specific enamel defects in Dutch children with coeliac disease as compared with children in the control group. Dentists could play an important role in recognizing patients with coeliac disease.

PURPOSE: The aim of this study was to describe and quantify the therapeutic value of platelet concentrate on the capillary density in oral mucosal wound healing. MATERIAL AND METHODS: The subjects included 10 healthy edentulous patients who underwent bilaterally a sinus floor elevation procedure and a buccal onlay graft with autologous iliac crest bone for maxillary reconstruction. During surgery, platelet-rich plasma (PRP) was prepared from a blood sample taken from the patient. After randomization in a split-mouth design, at one side PRP was administered in the wound and at the contralateral side a placebo. At baseline, microvascular capillary density was scored with the orthogonal polarization spectral (OPS) imaging technique and repeated measurements were performed postoperatively on a daily basis until the tenth day, after which measurements were continued weekly until the fifth postoperative week. RESULTS: Ten patients, five males and five females, were included in the study with a mean age of 54.2+/-9.1 years for females and 57.6+/-6.9 years for males. Donor platelet counts from whole blood had a mean value of 248.5+/-13.5 x 10(9)/l, while the value of platelet counts in the PRP had a mean of 975.9+/-97.9 x 10(9)/l. Wound healing was significantly accelerated in the PRP-treated mucosal wounds during the first 10 postoperative days. After the second week, no obvious differences between the PRP or placebo side could be noted. CONCLUSION: PRP has a strong stimulant effect on capillary regeneration in wound healing. These effects are mainly noticeable during the early stages of wound healing.

This double-blind study used a split-mouth design to investigate the microbiological and clinical effects of 0.2% chlorhexidine enclosed in fixtures. Twelve patients had 46 fixtures implanted. At second-stage surgery, a microbiological sample (baseline sample) of the inner parts of the fixtures was taken. Then, a 0.2% chlorhexidine solution was applied into the inner space of 23 fixtures (test group), and in 23 fixtures saline was applied (control group). Abutments were installed and gingival index, plaque index and crevicular fluid flow were monitored weekly. After 6 weeks, a second microbiological sample of the inner part of the fixtures was taken. At baseline, viable bacteria were detected within 46% of the fixtures. After weeks, bacteria were found in 87% of the fixtures. The numbers of bacteria in the control group were significantly higher than those in the test group. The results indicate that, after first-stage surgery, contamination of the inner spaces of the fixtures is commonplace. Application of a 0.2% chlorhexidine solution at second-stage surgery inhibits growth or acquisition of bacteria in the fixtures. In both test and control groups, the crevicular fluid flow as well as the gingival index decreased during the experimental period. At 4, 5, and 6 weeks after chlorhexidine application, these values in the test group appeared lower, but did not attain statistical significance.
