Objective: To analyze and identify changes in the maxillary dental arch before and after cheiloplasty in a group of unilateral complete cleft lip and palate (UCLP) infants. Design: This is a cohort study. Material and Method: Study models from 16 infants with nonsyndromic UCLP, who were treated at Khon Kaen University, were taken before (T1) and after cheiloplasty (T2). The dental models underwent a process of scanning through a 3D scanner, from which 9 linear and 2 angular landmarks were evaluated. Paired t test was used to compare the measurement statistically between T1 and T2. Results: Alveolar cleft gap (G-L), anterior basal angle (∠GC-CC′), and anterior arch curvature angle on greater segment (∠GIC) were significantly decreased ( P < .05). Contrarily, anterior ridge length of greater segment (C-I), anterior ridge length of lesser segment (L-C′), and posterior arch width (T-T′) were significantly increased ( P < .05) after cheiloplasty. While, anterior portion of greater segment (I-G), anterior arch width (C-C′), anterior arch depth (I⊥CC′), arch length (G⊥TT′), and arch circumference (T-C-I-G-L-C′-T′) showed no significant difference. The measurements were tested using the Intraclass correlation coefficient. The coefficients indicated high reliability. Conclusion: Cleft gap significantly decreased after lip repair, and the anterior part of maxillary dental arch was also bent palatally after cheiloplasty without any other intervention except cheiloplasty. More studies are needed to assess the amount of lip pressure. If any convincing force is presented, an appliance to prevent undesirable pressure is indicated.
Objective This study aimed to review all research evidence of presurgical cleft size and related factors to success of secondary alveolar bone grafting (SABG). Design and Setting The systematic review searched the OVID-Medline®, PubMed®, Embase®, and Cochrane Central Register of Controlled Trials (CENTRAL) up to August 2020. Two reviewers independently selected potential abstracts for full review. Disagreeements were resolved by consensus. The first author extracted data and assessed the risk of bias using Risk of Bias in Non-randomized studies—of Interventions tool. Patients and Interventions Patients with non-syndromic clefts who received SABG were selected. Presurgical cleft size/volume and treatment results must be available. Main Outcome Measures Level of the grafted bone, achievement of orthodontic tooth movement into the grafted area, need for re-operation. Results From 962 abstracts, 23 publications were included. Mean cleft width was 6.80 ± 1.98 mm, cleft area 20–240 mm2, and mean volume 0.89 ± 0.33 cm3. No definite conclusion was achieved on whether a narrow or wide cleft showed better treatment outcomes, but other potentially related factors were good oral hygiene and eruptive force of the maxillary canines. Lack of a standard definition of cleft size, a small sample size, varying outcome parameters, and moderate-to-high risk of bias contributed to the summary. A meta-analysis could not be performed because of the heterogeneity. Conclusion Due to insufficient evidence, cleft width/volume could not be specified leading to more successful SABG. Care of patients could be improved in both research by following rigorous methodology, and practice by clear communication.
Objective: To evaluate dental changes in cleft patients after undergoing orthodontic treatment for at least 2 years. Hypothesis: The dental change would decline significantly after 2 years of completing orthodontic treatment. Design: This is a retrospective study. Patient: Eighteen repaired cleft lip and palate patients from the Faculty of Dentistry, KhonKaen University, Thailand, participated in this study. Mean Outcome Measures: A dental model with before treatment (T0), completed treatment (T1), and retention period (T2) data was analyzed using the peer assessment rating (PAR) index. Result: The results showed that the PAR score improved enormously after treatment; from T0 to T1, it was 34.00 ± 10.01 to 4.67 ± 2.47, and there was a reversion in the retention period. There was statistical significance between T0, T1, and T2, with P values <.001, .005, and <.001 when comparing T0 with T1, T1 with T2, and T0 with T2, respectively. Conclusion: Occlusion in cleft lip and palate patients changed from the time of completing treatment to the final results after the retention period. To sustain satisfactory results, orthodontists should plan carefully for the retention period before performing the treatment.
Objective: This study aimed to observe and analyze the effects of nasoalveolar molding (NAM) on maxillary arch dimensions in patients with bilateral complete cleft lip and palate (BCLP) using 3-dimensional analyses. Design: Retrospective case series. Materials and Methods: Seventeen infants were treated using modified Khon Kaen University presurgical nasoalveolar molding devices (KKU-NAM). Dental casts were evaluated 3 dimensionally at 3 time points: pretreatment (T1), after using modified KKU-NAM for 2 weeks (T2), and before cheiloplasty (T3). Repeated-measures analysis of variance and Friedman test were used to compare the maxillary arch dimensions between time points. Results: Both sides of the cleft width, premaxilla deviation, and premaxilla protrusion had significantly reduced with the use of KKU-NAM. Premaxillary rotation had significantly improved, whereas the arch depth did not change significantly. Premaxilla width, posterior arch width, alveolar length, and height had significantly increased. The anterior arch width, intercanine width, and lateral sulcus width showed no significant changes. The intraclass correlation coefficient used to test the measurements indicated substantial reliability. Conclusion: The modified KKU-NAM is an effective device for reducing the severity of bilateral cleft deformities, especially in the premaxilla area.
PurposeThis study aimed to evaluate the trabecular bone changes after alveolar bone grafting in unilateral cleft lip and palate (UCLP) patients using a computer-aided diagnosis (CAD) system.Materials and MethodsThe occlusal radiographs taken from 50 UCLP patients were surveyed retrospectively. The images were categorized as: 50 images in group 0 (before bone grafting), 33 images in group 1 (one month after bone grafting), 24 images in group 2 (2-4 months after bone grafting), 15 images in group 3 (5-7 months after bone grafting), and 21 images in group 4 (8 or more months after bone grafting). Each image was grouped as either "non-cleft side" or "cleft side". The CAD system was used five times for each side to calculate the pixel area based on the mathematical morphology. Significant differences were found using a Wilcoxon signed ranks test or paired samples t test.ResultsThe pixel area showed a significant difference between the "non-cleft side" and "cleft side" in group 0 (404.27±103.72/117.73±92.25; p=0.00), group 1 (434.29±86.70/388.31±109.51; p=0.01), and group 4 (430.98±98.11/366.71±154.59; p=0.02). No significant differences were found in group 2 (423.57±98.12/383.47±135.88; p=0.06) or group 3 (433.02±116.07/384.16±146.55; p=0.19).ConclusionBased on the design of this study, alveolar bone grafting was similar to normal bone within 2-7 months postoperatively.
Cleidocranial dysplasia (CCD) is a rare congenital disorder with prolonged retention of the primary teeth, unerupted permanent teeth, and supernumerary teeth. We report a 19-year-old well-developed and well-nourished Thai woman who presented with intermittent dull pain in the lower left jaw for about a week. CCD was diagnosed based on a panoramic radiograph that revealed 32 unerupted teeth affecting all four quadrants of her jaw. Chest and skull radiographs were added to evaluate the clavicles and skull bone formation to confirm the diagnosis of CCD. Family members, including parents and siblings, were radiographically investigated and showed no abnormality. After a 6-h first operation in the lower left jaw to remove five supernumerary teeth, a deciduous canine, and a permanent third molar, three-dimensional imaging by cone-beam computed tomography was conducted as an aid for planning further dental surgery and orthodontic treatment. A second operation was conducted to remove the other unerupted teeth in the four quadrants in 6 h, the same as the initial operation time, although the second involved the whole jaw, as compared with the first operation in only one quadrant.
Background: Cleft Lip and Palate (CLP) negatively affect the quality of life (QoL) and nasolabial appearance, especially in preteen patients who start to be interested in their own appearance and society. Objective: The objective of this study is to evaluate the cost-effectiveness of plastic surgery for Thai preteen CLP patients through their satisfaction with their QoL and nasolabial appearance. Methods: A cross-sectional study covered purposively selected 30 samples aged between 8 and 12 years old.Their satisfaction with their QoL and appearance was reflected through an interview and a questionnaire with the cooperation of their parents as their caregivers including satisfaction with their nasolabial appearance evaluated by five experts. They compared the photos of patients’nasolabial appearance with those of normal faces of children of the same age using 5-rating scales. Results: General findings showed 53.3% of samples were male patients with mostly (63.3%) UCLP whose parents were mainly (73.3%) poor, so they relied on government financial supports for the treatment. Only some (15%) earned up to 5,001 to 10,000 baht per month because of their low education with just high school level. Specific findings indicated the overall satisfaction with QoL through five dimensions at average level (3.26±1.39). This was based on the satisfaction with the center services, the overall treatments, the medical additional costs, parental satisfaction with psychosocial effects including concerns about the impacts of CLP on the family ranged from high to low i.e. 4.30±0.98, 3.72±1.15, 3.70±1.14, 3.33±1.08 and 2.81±1.46 respectively. Moreover, five experts trended to be highly satisfied with patients’ nasolabial appearance by rating it from Good (53.3%) to Fair (43.43%) with only Poor (3.3%). Conclusion: The good cost-effectiveness of the surgery was represented through the average and high satisfaction of CLP patients with their QoL and their appearance respectively indicating the absence of disability weights for these treated CLP patients.
