Abstract
This systematic review summarises evidence regarding oral nutritional supplement (ONS) use in children with, or at risk of, faltering growth (FG). Ten randomised controlled trials (RCTs), compared changes in outcomes amongst children receiving ONS versus control were included. Overall, 1116 children (weighted mean (WM) age 5 years; n658 (59%) male) were recruited, of which 585 (52%) received ONS (WM intake contribution 412 kcal, 16.3 g protein, 395 ml) for 116 days (WM). ONS use was associated with significantly greater gains in weight (mean difference (MD) 0.4 kg, 95% CI [0.36, 0.44]) and height (MD 0.3 cm, 95% CI [0.03, 0.57]), likely related to improvements in nutritional intake. Mean compliance to prescribed dose was 98%. Data suggested an association between ONS use and reduced infections. Further research is warranted to establish ONS dosage and effects upon other outcomes. This review provides evidence to support use of ONS in the management of children with, or at risk of, FG.

A systematic review and meta-analysis of the effects of community use of oral nutritional supplements on clinical outcomes. Ageing Res Rev 2023; 88:101953. [PMID: 37182743 DOI: 10.1016/j.arr.2023.101953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 04/28/2023] [Accepted: 05/11/2023] [Indexed: 05/16/2023]
Abstract
The impact of oral nutritional supplements (ONS) on patients with complications (disease related morbidity) requires further exploration. This systematic review included 44 randomised controlled trials (RCT) (29 RCT surgical, 15 RCT medical patients) examining the effect of ONS in community settings on the incidence of complications (n = 716, mean age 67 years, range 35-87). ONS (mean intake 588 kcal/day, range 125-1750; protein 22 g/day, range 0-54; mean energy from protein 22 %, range 0-54) were prescribed for a mean 74 days, range 5-365. Most RCT (77 %) reported fewer complications in the ONS group versus control. Meta-analysis (39 RCT) showed ONS consumption reduced complications including infections, pressure ulcers, wound and fracture healing (OR 0.68, 95 % CI 0.59,0.79; p<0.001). Results showed reductions when ONS were used in hospital and community settings (OR 0.72, 95 % CI 0.59,0.87; p = 0.001) or just in the community (OR 0.65, 95 % CI 0.52, 0.80; p<0.001). Reductions in complications were only seen with high ONS adherence ≥ 80 % (OR 0.63, 95 % CI 0.48,0.83; p = 0.001) and ready-to-drink ONS (OR 0.69, 95 % CI 0.60,0.81; p<0.001). This systematic review and meta-analysis show community-based use of ONS in addition to the diet substantially reduces the incidence of complications. The diversity of ONS, patient populations and complication outcomes within the trials included in this review mean further research is warranted.

Abstract
Disease-related malnutrition is common, detrimentally affecting the patient and healthcare economy. Although use of high protein oral nutritional supplements (ONS) has been recommended to counteract the catabolic effects of disease and to facilitate recovery from illness, there is a lack of systematically obtained evidence to support these recommendations. This systematic review involving 36 randomised controlled trials (RCT) (n=3790) (mean age 74 years; 83% of trials in patients >65 years) and a series of meta-analyses of high protein ONS (>20% energy from protein) demonstrated a range of effects across settings and patient groups in favour of the high protein ONS group. These included reduced complications (odds ratio (OR) 0.68 (95%CI 0.55-0.83), p<0.001, 10 RCT, n=1830); reduced readmissions to hospital (OR 0.59 (95%CI 0.41-0.84), p=0.004, 2 RCT, n=546); improved grip strength (1.76 kg (95%CI 0.36-3.17), p<0.014, 4 RCT, n=219); increased intake of protein (p<0.001) and energy (p<0.001) with little reduction in normal food intake and improvements in weight (p<0.001). There was inadequate information to compare standard ONS (<20% energy from protein) with high protein ONS (>20% energy from protein). The systematic review and meta-analysis provides evidence that high protein supplements produce clinical benefits, with economic implications.

Abstract
BACKGROUND Scleroderma renal crisis (SRC) is an important complication of systemic sclerosis, causing acute renal failure, and usually hypertension. AIMS To review the clinical and pathological features of SRC, and correlate them with renal outcomes and mortality. DESIGN Retrospective case series. METHODS We identified 110 cases of SRC managed at a single centre between 1990 and 2005. RESULTS SRC occurred in 5% of scleroderma cases under follow-up. Cases were predominantly female (81%), with diffuse cutaneous disease (78%). RNA polymerase antibodies were found in 59% of cases tested. Almost all (108/110) received treatment with ACE inhibitors (ACEIs). Dialysis was not required in 36%, was required temporarily (for up to 3 years) in 23%, was required permanently in 41%. Patients not on dialysis showed improvement in estimated glomerular filtration rate after SRC (mean change +23 ml/min over 3 years). Poor renal outcome was associated with lower blood pressure at presentation, and with higher age in those requiring dialysis. Steroid use, microangiopathic haemolytic anaemia, and antibody profile were not related to renal outcome. In the 58 renal biopsies available for clinical correlation, acute changes of mucoid intimal thickening in arteries and fibrinoid necrosis in arterioles were associated with a poorer renal outcome. Mortality was high (59% survival at 5 years), and was higher in men. DISCUSSION Despite the efficacy of ACEIs in managing SRC, the poor long-term outcome warrants evaluation for additional treatments for this devastating complication of systemic sclerosis.

Enteral (oral or tube administration) nutritional support and eicosapentaenoic acid in patients with cancer: a systematic review. Int J Oncol 2006; 28:5-23.

Abstract
The aim of this systematic review was to determine the efficacy and potential benefits of enteral nutritional support [oral nutritional supplements (ONS) or enteral tube feeding (ETF)], and eicosapentaenoic acid (EPA, free acid, ethyl esters or fish oil; provided as capsules or enriched ONS or ETF) in patients with cancer. Clinical studies were identified using electronic databases, and studies were selected according to predetermined criteria. For each treatment modality (chemo/radiotherapy, surgery, and palliative care), the comparisons of interest were nutritional support vs. routine care (no nutritional support), EPA supplement (capsule or enriched ONS or ETF) vs. routine care (no supplement or standard supplement), ETF vs. parenteral nutrition (PN). The reviewed outcomes were dietary intake, anthropometry, clinical (mortality, length of hospital stay, complications, and quality of life) and haematological/biochemical (white blood cell count, serum transferrin and albumin, CD3-positive lymphocytes, and inflammatory markers). Meta-analyses were performed where possible. In patients undergoing radiotherapy, meta-analysis showed that ONS significantly increase dietary intake (381 kcal/day, 95% CI 193 to 569 in 3 RCTs) compared to routine care. In patients undergoing surgery, meta-analyses showed that ETF results in a significantly shorter length of hospital stay (1.72 fewer days, 95% CI 0.90 to 2.54 in 8 RCTs), lower incidence of any complications (OR 0.62, 95% CI 0.50 to 0.77 in 4 RCTs) and infectious complications (OR 0.67, 95% CI 0.55 to 0.82 in 11 RCTs) and lower sepsis scores (2.21 points, 95% CI 1.49 to 2.92 in 2 RCTs), but no difference in mortality (OR 0.72, 95% CI 0.40 to 1.29 in 7 RCTs) compared to PN. There was also no difference in mortality between ONS or ETF vs. routine care in patients undergoing chemotherapy/radiotherapy (OR 1.00, 95% CI 0.62-1.61 in 4 RCTs) or surgery (OR 2.44, 95% CI 0.75 to 7.95 in 4 RCTs). Individual studies of EPA supplementation as capsules showed improvements in survival, complications and inflammatory markers in patients undergoing bone marrow transplant (BMT). In palliative care patients receiving EPA-enriched ONS or capsules, there were inconsistent positive effects on survival and quality of life. In those undergoing surgery, EPA-enriched ETF had no effect. Further research is required to elucidate the clinical efficacy of enteral nutrition support, including the potential benefits of EPA supplementation, in patients with cancer.

Abstract
BACKGROUND There is some controversy about whether all adults receiving healthcare should be routinely screened for nutritional problems. METHODS (i) A systematic review examined the proposition that malnutrition is under-recognised and under-treated, and that nutritional interventions in malnourished patients, identified through a screening procedure produce clinical benefits (assessed using randomised controlled trials, RCTs). (ii) A systematic review of nutritional screening interventions in populations of malnourished and well-nourished subjects (RCTs and non-RCTs). RESULTS (i) The prevalence of malnutrition varies according to the criteria used, but is estimated to affect 10-60% of patients in hospital and nursing homes, 10% or more of older free-living subjects, and less than 5% of younger adults. In the absence of formal screening procedures, more than half the patients at risk of malnutrition in various settings do not appear to be recognised and/or are not referred for treatment. RCTs show that nutritional interventions in malnourished patients produce various clinical benefits. (ii) Interventions with nutritional screening in different care settings also generally suggest clinical benefits, but some are limited by small sample sizes and inadequate methodology. Factors that influence outcomes include validity, reliability and ease of using the screening procedure, the 'care gap' that exists between routine and desirable care and the need for other resources, which may increase or decrease following screening. CONCLUSIONS The frequent failure to recognise and treat malnutrition, especially where it is common, is unacceptable. In such circumstances, the routine use of a simple screening procedure is recommended. Each health care setting should have a transparent policy about nutritional screening, which may vary according to the 'care gap', available resources, and specific populations of patients, in which the prevalence of malnutrition may vary widely.

Serological assessment of type I collagen burden in scleroderma spectrum disorders: a systematic review. Clin Exp Rheumatol 2004; 22:356-67.

Abstract
RATIONALE The aim of the study was to evaluate the validity of collagen type I metabolites as markers of disease activity in scleroderma (SSc), through a systematic review of the literature and by validating the results by measuring collagen type I metabolites in well characterized patients with scleroderma spectrum disorders and in Raynaud's phenomenon. METHODS A systematic review was performed of studies of collagen type I metabolites in scleroderma spectrum disorders published from 1980 to 2003. The collected results from the literature were compared with our own measurements of collagen type I metabolites (PINP and ICTP) in a small number of well characterized patients within the scleroderma spectrum and in patients with primary and "autoimmune" Raynaud's phenomenon. Peptide concentrations from all sources, including the present study, were compared. Reported correlations between peptide concentrations and clinical variables were also analysed. RESULTS Of 19 papers identified by an extensive Medline search, 12 were eligible for systematic analysis. There was a considerable heterogeneity in the results with a wide range of metabolite concentrations. Values from disease groups and healthy controls overlapped. These findings were confirmed by our study where, similarly, there was a large range of values in all groups, but particularly in the diffuse SSc subset. When the correlation between peptide levels and clinical variables was assessed, large discordance between the studies was observed. CONCLUSIONS We have not found sufficient evidence to support the use of serum markers of collagen turnover in the assessment of scleroderma activity and severity, in view of their low specificity and the heterogeneity of the results of various studies. Lack of standardized routine evaluation of SSc patients in clinical studies might have accounted for the variability of the findings. However, due to the small sizes of most published studies, demonstration of no effect should come from large-scale randomised trials. Longitudinal serial analysis of these molecules in individual patients may play a future role in the evaluation of the response to fibroblast-targeting therapeutic strategies in scleroderma patients.

Abstract
BACKGROUND AND AIMS In the UK, cerebrovascular accident (CVA) is the third commonest cause of death and the commonest diagnosis in patients receiving home enteral feeding (HETF). This study aimed to use data from the British Artificial Nutrition Survey (BANS) collected between 1996 and 1999 to assess the outcome of patients on HETF, including mortality, return to oral feeding, level of physical activity, and level of dependency, which has resource implications. RESULTS it is estimated that about 1.7% of all patients suffering a CVA in the UK between 1996 and 1999 received HETF. At one year, 29.6% died while receiving HETF and another 13% returned to oral feeding. Mortality increased with age and was twice as high in those managed in nursing homes compared to those in their own homes. The patients receiving tube feeding spent only 0.6% of their time in hospital. A total of 43.9% of patients were bed-bound at home (1.9% unconscious) and an additional 30.3% were house-bound. Only 21.2% were independent, and the majority were totally dependent on their carers. In CVA patients on HETF the level of dependency was greater than for those with all types of diagnoses (n=12,997). CONCLUSION This study has described the outcome of a large number of patients receiving HETF in the UK. Since patients spent less than 1% of their time in hospital, HETF relieves pressure on the expensive hospital environment, but places more demands on the carers, who have to deal with severely disabled patients. Recovery of swallowing function should be assessed intermittently to prevent unnecessary HETF.

Abstract
OBJECTIVE To assess the safety and efficacy of anti-thymocyte globulin (ATG) followed by mycophenolate mofetil (MMF) in the treatment of diffuse scleroderma. METHODS A pilot study of 13 patients with recent-onset diffuse scleroderma was carried out. Patients received ATG for 5 days, followed by MMF for 12 months. We recorded adverse events, scleroderma skin score, hand contractures, EuroQol score, scleroderma functional assessment, pulmonary function studies, echocardiogram and plasma creatinine concentration. RESULTS Mean skin score decreased during the study from 28 at baseline to 17 after 12 months of MMF (P<0.01). Hand contractures worsened during the study. Mean measurements of systemic disease remained stable. One patient died after a scleroderma renal crisis. Five patients developed serum sickness after ATG treatment, but this was controlled by corticosteroid therapy. MMF therapy was well tolerated. CONCLUSION ATG and MMF appear safe in scleroderma. The improvement in skin score and the apparent stability of systemic disease during the study period suggest that controlled studies of these agents are justified.

Abstract
Despite a marked increase in the prescription of oral nutritional supplements (ONS) in the community (Department of Health, 1991-7), there is still uncertainty about the value of their use in patients with different diseases. To answer questions about the effects on ONS on body weight and structure, spontaneous food intake and body function, a critical systematic review was undertaken (Stratton & Elia, 1999a). Eighty-four trials were reviewed (forty-five randomized, thirty-nine non-randomized: 2,570 patients; diagnoses including chronic obstructive pulmonary disease, Crohn's disease, cystic fibrosis, human immunodeficiency virus and acquired immune deficiency syndrome and cancer). Most studies (83 %) were conducted in patients living at home. The supplements were typically mixed macronutrients in liquid form, providing < 0.42-10.5 MJ/d for 1 week-2 years. The studies reviewed in patients with predominantly chronic conditions living in the community suggested that: (1) ONS produce demonstrable clinical (including functional) benefits, but the nature and extent of these benefits varies with the underlying chronic condition; (2) ONS increase total energy intake with > 50 % of the energy from ONS typically additional to that from habitual food intake; (3) improvements in body weight, total energy intake and body function following ONS appear to occur more frequently in individuals with a BMI < 20 kg/m2 than in those with a BMI > 20 kg/m2.

Abstract
OBJECTIVE To investigate tolerability and efficacy of low molecular weight (LMW) heparin therapy in patients with severe Raynaud's phenomenon. METHODS A prospective parallel group study comparing patients receiving regular subcutaneous LMW heparin (n = 16) with a matched control group (n = 14). Endpoints were change in Raynaud's attack severity, non-invasive vascular studies or serum levels of circulating soluble adhesion molecules. RESULTS There was overall improvement in Raynaud's attack severity during heparin therapy (p = 0.0002). This was observed after 4 weeks, and was maximal by 20 weeks. Mean finger blood flow recovery time improved, and serum levels of circulating ICAM-1, VCAM-1 and E-selectin were lower at completion of heparin therapy, but changes did not reach statistical significance. CONCLUSION This study suggests that LMW heparin therapy is well tolerated, and potentially beneficial, in patients with severe Raynaud's phenomenon, and justifies further evaluation.

Abstract
OBJECTIVE To investigate the expression of thrombomodulin in scleroderma associated pulmonary hypertension. METHODS Soluble thrombomodulin (sTM), was measured in plasma samples from 34 scleroderma patients shown to have pulmonary hypertension at echocardiogram, and comparison drawn against samples from 38 scleroderma control patients, and 20 healthy controls. Serial measurements of sTM were performed in the 34 patients with scleroderma associated pulmonary hypertension to investigate possible changes in sTM concentration with progression of the condition. RESULTS Mean sTM was raised in scleroderma associated pulmonary hypertension when compared with scleroderma controls (mean sTM 65.4 ng/ml v 43.3 ng/ml, p<0.05), and when compared with healthy controls (mean sTM 38.1 ng/ml, p<0.05). There was no significant difference between mean sTM in scleroderma controls and healthy controls. Mean sTM concentration did not change with progression of pulmonary hypertension. CONCLUSION Plasma sTM is raised in scleroderma associated pulmonary hypertension. The pathogenesis of scleroderma associated pulmonary hypertension may be distinct from the pathogenesis of other forms of pulmonary vascular disease.

Abstract
Enteral tube feeding (ETF) and parenteral nutrition (PN) are unphysiological methods of feeding. They may not elicit the cephalic phase response because part or all of the gastrointestinal tract is bypassed, nutrients are typically given in liquid form by a continuous infusion over many hours and often overnight while patients sleep. Work conducted in animals, healthy subjects and patients suggests that nutrients delivered as ETF or PN are less effective in relieving appetite sensations than food intake. Distressing appetite sensations may even occur despite the provision by artificial nutrition of sufficient nutrients to meet requirements. The energy provided by ETF and PN is largely additional to oral food intake in humans eating ad libitum, although the extent to which this occurs may decrease with time. There is a need to establish ways (e.g. nutritional, pharmacological, psychological) to suppress appetite sensations and food intake when eating is contraindicated, and to enhance them when weaning from artificial nutrition is desirable.

Abstract
BACKGROUND Tube feeding is an unphysiological route of nutrient delivery, and yet there is a lack of controlled trials examining its effects on appetite, food intake, and factors involved in their control. This study aimed to investigate the relationship between diurnal tube feeding, hunger, food intake, and circulating concentrations of leptin (a putative satiety factor). METHODS Six healthy lean men received a continuous nasogastric infusion (9:00 AM to 9:00 PM) of colored water (2 days), liquid feeding (4.2 kJ/mL, energy provision 1 x the initial predicted basal metabolic rate; 3 days), and colored water (2 days). Measurements of hunger (visual analog scales), weighed food intake, and fasting circulating leptin concentrations were made while the subjects were allowed free access to isoenergetically dense food items. RESULTS Three days of diurnal nasogastric feeding (mean, 6.9 MJ/d) significantly increased total energy intake (to 19.4 MJ/d; p < .001; analysis of variance [ANOVA]), suppressing oral energy intake by only 17%, with no significant effect on mean daily hunger. Higher levels of energy intake led to a universal rise in circulating leptin concentrations (2.82 to 4.23 ng/mL; p < .004; ANOVA) that was not significantly related to subsequent breakfast energy intake, first rated hunger of the day, timing of morning food consumption, or subsequent mean daily oral energy intake or hunger. CONCLUSIONS This study suggests that 3 days of diurnal tube feeding (equivalent to basal metabolic rate) failed to suppress hunger and reduced food intake by only 17%. The rise in circulating leptin concentrations, associated with tube feeding and the increase in total energy intake, failed to predict subsequent hunger or oral energy intake.

Abstract
OBJECTIVE Assessing the value of a newly developed electronic visual analogue scale questionnaire (Apple Newton Message Pad) with the traditional paper method for appetite rating. DESIGN In a random, crossover design, subjects completed both electronic and paper questionnaires to compare results obtained by the two methods; individual methods were completed consecutively to assess test-retest reliability; preference was established using a questionnaire. SETTING/SUBJECTS Healthy, free-living adults were studied for comparison of methods (n = 12), test-retest reliability (n = 8) and preference (n = 13). INTERVENTION Visual analogue scales were completed each waking hour to assess appetite. Preference was assessed after both methods were completed. RESULTS There was no significant difference in the hourly results obtained by the paper and electronic methods for 'desire to eat', 'how much can you eat now', 'urge to eat' and 'preoccupation with thoughts of food'. Small differences in 'hunger' and 'fullness' ratings were noted (approximately 5% mean difference between methods, P < 0.05), but patterns of change and sensitivity for these and all other parameters remained similar for both methods across the visual analogue scale. Test-retest reliability demonstrated was similar for both methods. Seven (54%) subjects preferred to use the paper questionnaire, five (38%) the electronic method and one (8%) had no preference. CONCLUSIONS The electronic Apple Newton questionnaire is as sensitive and reliable as the paper method, has the advantage that it automatically records the time of data acquisition and data collection and processing are more efficient for the researcher. The two methods should not be used interchangeably.

Abstract
Abnormal endothelial cell function is implicated in the development of scleroderma, and in major life-threatening complications of the disease. The nature of the stimulus leading to abnormal endothelial cell function in scleroderma, scleroderma renal crisis, and scleroderma-associated pulmonary hypertension was investigated by measurement of soluble adhesion molecules, shed by activated endothelial cells, in sera from patients with these conditions. In scleroderma renal crisis, mean levels of soluble E-selectin (p < 0.05 limited scleroderma, p < 0.0001 diffuse scleroderma), sVCAM-1 (soluble vascular cell adhesion molecule-1) (p < 0.05 limited scleroderma, p < 0.05 diffuse scleroderma), and sICAM-1 (soluble intercellular adhesion molecule-1) (p < 0.0001 limited scleroderma, p < 0.0001 diffuse scleroderma) were raised, supporting a model of endothelial cell activation in this complication. Evidence for endothelial cell activation in scleroderma-associated pulmonary hypertension was inconsistent, with normal sE-selectin and normal sVCAM-1 in sera from patients with limited scleroderma and pulmonary hypertension. The endothelial cell phenotype in scleroderma-associated pulmonary hypertension may resemble that of unstimulated cells. The pulmonary vascular and renal vascular lesions associated with scleroderma may arise by distinct pathogenic mechanisms.

Abstract
1. This study aimed to investigate the possible role of leptin in post-traumatic anorexia by making pre- and post-operative (0-8 days) measurements of circulating leptin concentrations in six patients undergoing elective total hip replacement for osteoarthritis. 2. Mean daily hunger rating (four categories) and food intake (assessed by food record charts) were measured pre-operatively, as well as post-operatively for the first 5 days (days 0-5). Leptin concentrations, circulating metabolites [glucose, non-esterified fatty acids, glutamine and 3-hydroxybutyrate] and insulin and cortisol concentrations were measured pre-operatively (day 0) and post-operatively (days 1, 2, 3, 5 and 8). 3. Mean leptin concentrations were significantly increased only on day 1 (56% increase compared with pre-operative values, P < 0.009), whereas food intake (only 0.6 MJ on day 0) and hunger (5/6 patients 'not hungry' on day 0) only gradually improved over the next few days. (The energy intake over the first 5 days was 56% of the pre-operative value.) 4. Circulating insulin and cortisol concentrations were elevated on day 1 compared with pre-operative values on day 0 (P < 0.05). Of the measured metabolites implicated in the control of food intake, circulating non-esterified fatty acids and 3-hydroxybutyrate were not significantly altered in the post-operative period, but significant hyperglycaemia was noted on day 1 compared with day 0 pre-operatively (8.8 compared with 6.4 mmol/l glucose; P < 0.01). 5. It is concluded that circulating leptin is involved in the early (< 24 h) acute-phase response after moderately severe surgical trauma (characterized biochemically by a substantial acute-phase protein response, hypoalbuminaemia, hyperglycaemia and hypoglutaminaemia). Therefore, leptin may be implicated in post-traumatic anorexia, although other factors are likely to be involved, especially after the first 24 h when circulating leptin concentrations are no longer elevated.

Abstract
The continuous assessment and updating of clinical evaluations are integral aspects of dental education. The purpose of this article was to describe the development, implementation, and assessment of an evaluation system for clinical removable prosthodontics. A system based on a three-point scale (RST) was adopted and implemented with the intent of maximizing evaluation effectiveness while minimizing stress on students and faculty members. To date, the RST system has improved both the quality of clinical evaluation and the level of clinical learning. The RST clinical evaluation system appears to be defusing students' ardent quests for grades while promoting the teaching potential within the evaluation process. The system also stimulates student self-evaluation, improves the consistency of faculty grading, facilitates student counseling, and permits an in-depth analysis of the evaluation system at regular intervals.

Abstract
The quality of retention produced by a half-round cast clasp is affected by its curvature in the plane of its flat side. Uncurved clasps and those that curve 90 degrees, 180 degrees, and 270 degrees become progressively stiffer. Conversely, as the radius of the curvature increases, so does the flexibility of the clasp.

Abstract
A method of fabricating similar methyl methacrylate cylinders was used to produce specimens to test the bond strength of alpha cyanoacrylate and autopolymerizing methyl methacrylate. Each group was tested immediately and after storage in 37 degrees C water bath for 90 days. Statistical analysis supported the finding that the autopolymerizing methyl methacrylate produced a better bond even without undercuts or mechanical retention.
