Accuratezza e attendibilità delle misurazioni condilari mediante TAC Cone Beam nei pazienti con Artrite Idiopatica Giovanile - Accuracy and reliability of Cone Beam Computed Tomography condylar measurement in Juvenile Idiopathic Arthritis
No full textScopo del lavoro: Valutare in pazienti affetti da Artrite Idiopatica Giovanile (JIA) la relazione tra i segni e sintomi clinici e l’evidenza di lesioni articolari nelle immagini tridimensionali mediante Cone Beam TC. Inoltre sono state considerate le valutazioni cliniche, radiografiche metriche e temporali da un punto di vista statistico. Materiale e Metodi: 30 pazienti affetti da JIA sono stati considerati e sottoposti a TC Cone Beam (CBCT). Sono state eseguite misurazioni quantitative tridimensionali: diametro medio-laterale, diametro antero superiore e angoli condilari. Sono state calcolate le percentuali, le deviazioni standard e gli intervalli di confidenza (CI) delle variabili temporali, metriche, cliniche e radiografiche. Risultati: Le lesioni più comuni sono state: erosione nel 44%, l’appiattimento nel 24,5% e la presenza di osteofiti nel 15%. Solo il 2% dei soggetti non presentava variabili condilari. La misura media del diametro antero-posteriore sia a destra che a sinistra è stata di 15 mm; la misura media del diametro medio laterale destro è stata di 8 mm, quella del diametro medio laterale sinistro è stata di 7mm. La percentuale media dell’angolo condilare destro è stata di 33° e quella del condilo sinistro di 36°. È stata evidenziata una differenza molto significativa nelle misure lineari ed angolari tra condilo affetto da JIA e condilo normale (p<0.01). I segni e sintomi clinici non sono risultati correlati alle lesioni distruttive dei condili viste mediante CBCT. Conclusioni: Nei pazienti con JIA, il coinvolgimento dell’articolazione temporo-mandibolare è spesso asintomatica e può portare a gravi disturbi della crescita cranio-facciale se non trattati in fase iniziale. Nessuno dei segni clinici o sintomi di disfunzione dell’ATM sono predittori di distruzione ossea dell’ATM. La CBCT fornisce informazioni utili nella diagnosi e nel trattamento di JIA, e rappresenta un miglioramento nel quantificare i cambiamenti morfologici del condilo.Aim: To examine the relationship between the clinical signs and symptoms of temporomandibular joint disorders and Cone Beam Computed Tomography (CBCT) evidence of destruction of these joints in children afflicted with Juvenile Idiopathic Arthritis (JIA). It has been evaluated from a statistical stand point the temporal, metric and clinical variables of the disease in order to plan an effective therapy. Materials and Methods: This study enrolled 30 patients with JIA. CBCT has been performed. 3D quantitative measures of the mid-lateral and anterior-posterior diameters and angles of the condyles were taken. The data were captured using an I-CATTM cone beam 3-D imaging system and processed using I-CAT Vision viewing software, which allows visualization and measurement of the images in three dimensions (3D). Averages, standard deviations and 95% confidence intervals (CI) of the temporal, metric and clinical variables available were performed. Results: The analysis of the condylar changes showed that the most apparent signs were the erosion (44%), the flattening (24.5%) and the presence of osteophytes (15%). Only 2% of the study subjects had no damage. The evaluation of metric diameters showed that the mean size of the right as well as left antero-posterior diameters were 15 mm, the mean of the right mid-lateral diameter was 8 mm and that of the left mid-lateral diameter was 7 mm . The average right angle was 33° and the average left angle was 36°. There was a very significant difference in the linear and angular measurements between healthy and affected condyles (p<0.01). Conclusions: Patients with CBCT evidence of TMJ damage cannot be identified reliably by clinical examinations. CBCT represents an improvement in quantifying the morphological changes of the condyle and mandible, gives an accurate picture of these structures in JIA and allows the acquisition of true measurements of the mandibular components even in the early stages of JIA
Alterazioni facciali morfologiche ed estetiche nell’Artrite Idiopatica Giovanile : misurazioni 3D lineari ed angolari
No full textScopo: L’Artrite Idiopatica Giovanile (AIG) può provocare nei bambini un danno all’articolazione temporomandibolare (A.T.M.) con alterazioni della crescita e dello sviluppo facciale. Se il danno temporomandibolare è bilaterale, si osserva una riduzione delle dimensioni mandibolari e si sviluppa una facies caratteristica denominata “bird face” in quanto il naso e la fronte sembrano più prominenti rispetto al terzo inferiore della faccia. Se il danno è monolaterale si sviluppano delle marcate asimmetrie nel volto di questi giovani soggetti. Lo scopo di questo studio è stato di valutare da un punto di vista statistico le variabili temporali, metriche e cliniche della malattia, al fine di pianificare una terapia efficace per limitare gli effetti erosivi sui condili mandibolari dei pazienti affetti da Artrite Idiopatica Giovanile (AIG) consentendo un armonioso sviluppo osseo e dentale.
Materiali e Metodi: Questo studio ha considerate 30 pazienti con AIG. Una Tomografia Computerizzata Cone Beam (CBCT) è stata eseguita per ogni paziente. Sono state prese le misure quantitative 3D del diametro medio-laterale ed anteriore-posteriore e degli angoli dei condili. I dati sono stati raccolti utilizzando un sistema di acquisizione delle immagini 3-D Cone Beam I-CATTM e trattati con un software di visualizzazione I-CAT Vision, che consente la visualizzazione e la misurazione delle immagini in tre dimensioni (3D). Medie, deviazioni standard e intervalli di confidenza del 95% (CI) delle variabili temporali, metriche e cliniche sono stati eseguiti.
Risultati: L'età media del campione studiato è 12,90 anni (95% CI: 11.29-14,50 anni) fino al 16 giugno 2009, l'incidenza della malattia si è verificato a 7,09 anni in media (95% CI: 5,63 - 8,55 anni). L'analisi dei cambiamenti condilari ha mostrato che i segni più evidenti sono stati l'erosione (per il 44% del campione), l'appiattimento (per il 24,5% del campione) e la presenza di osteofiti (per il 15%). Solo il 2% dei soggetti in studio non ha avuto danni.
La valutazione metrica dei diametri ha dimostrato che la dimensione media del diametro antero-posteriore di destra e di sinistra è stata 15 mm, la media del diametro medio-laterale destro è di 8 mm e quella del diametro medio-laterale sinistro è di 7 mm. L'angolo medio di destra era di 33° e l'angolo medio di sinistra è stata di 36 °. C'è una differenza molto significativa nelle misure lineari ed angolari tra condili sani e affetti (p <0,01).
Discussione: L'uso della CBCT e il protocollo diagnostico 3D nei giovani pazienti con AIG ha consentito immagini quantitative affidabili, accurate e precise delle strutture condilari e dei loro rapporti dimensionali. Nei pazienti con AIG, l’interessamento dell’articolazione temporomandibolare (ATM) è spesso asintomatico e può portare a gravi disturbi della crescita cranio-facciale ed a malformazioni facciali se non trattata in fase iniziale. L’artrite dell'ATM nei pazienti con AIG è difficile da diagnosticare in fase iniziale in quanto vi sono relativamente pochi sintomi e dati clinici. Il processo patologico può influenzare la crescita a lungo prima che i cambiamenti radiografici siano visti con le radiografie convenzionali.
Conclusioni: La CBCT fornisce informazioni utili a completare esami clinici e di laboratorio nella diagnosi e nel trattamento dell’AIG. I pazienti con evidenza sulla CBCT di danno dell’ATM non può essere identificato in maniera affidabile mediante esami clinici. La CBCT rappresenta un miglioramento nel quantificare i cambiamenti morfologici del condilo e della mandibola e permette di affrontare precocemente una terapia per ridurre la formazione di malformazioni facciali.Facial modifications in Juvenile Idiopathic Arthritis: three-dimensional linear and angular measurements.
Objective: The Juvenile Idiopathic Arthritis (JIA) can lead in children to temporomandibular joint damage with facial development and growth alterations. If the temporomandibular joint damage is bilateral, there are a small jaw with a characteristic face referred to as "bird face " because the nose and the forehead appear more prominent than the lower third of the face. If the damage is unilateral there is a marked asymmetry in the faces of these young subjects. The aim of this study was to evaluate from a statistical standpoint the temporal, metric and clinical variables of the disease in order to plan an effective therapy to limit the erosive effects on mandibular condyles of the patients affected by Juvenile Idiopathic Arthritis (JIA), allowing an harmonious dental and bone development.
Materials and Methods: This study enrolled 30 patients with JIA. A Cone Beam Computed Tomography (CBCT) has been performed. 3D quantitative measures of the mid-lateral and anterior-posterior diameters and angles of the condyles were taken. The data were captured using an I-CATTM Cone Beam 3-D imaging system and processed using I-CAT Vision viewing software, which allows visualization and measurement of the images in three dimensions (3D). Averages, standard deviations and 95% confidence intervals (CI) of the temporal, metric and clinical variables available were performed.
Results: The mean age of the study samples was 12.90 years (95% Cl: 11.29-14,50 years) up to 16 June 2009, the incidence of the disease occurred at 7.09 years on average (95% Cl: 5,63-8,55 years). The analysis of the condylar changes showed that the most apparent signs were the erosion (for 44% of samples), the flattening (for 24.5% of the samples) and the presence of osteophytes (for 15%). Only 2% of the study subjects had no damage. The evaluation of metric diameters showed that the mean size of the right as well as left antero-posterior diameters were 15 mm, the mean of the right mid-lateral diameter is 8 mm and that of the left mid-lateral diameter is 7 mm . The average right angle was 33° and the average left angle was 36°. There was a very significant difference in the linear and angular measurements between healthy and affected condyles (p<0.01).
Discussion: The use of CBCT and the 3D diagnostic protocol in young patients with JIA enabled reliable, accurate, and precise quantitative images of the condylar structures and of their dimensional relationships. In patients with JIA, temporomandibular joint (TMJ) involvement is often asymptomatic and can lead to severe craniofacial growth disturbances and facial deformities if not treated in the initial stage. TMJ arthritis in JIA patients is difficult to diagnose at an early stage, as there are relatively few symptoms and clinical findings. The pathological process can affect growth long before radiographic changes are seen by standard radiographs.
Conclusions: CBCT provides useful information to supplement clinical and laboratory examinations in the diagnosis and treatment of JIA. Patients with CBCT evidence of TMJ damage cannot be identified reliably by clinical examinations. CBCT represents an improvement in quantifying the morphological changes of the condyle and mandible and it allows to do early a therapy to reduce the formation of facial deformities
Ruolo dell’odontoiatra nella diagnosi e nella terapia dell’artrite psoriasica
No full textScopo: La psoriasi è una comune patologia cutanea infiammatoria la cui lesione caratteristica è rappresentata una placca ben demarcata e coperta da scaglie argentate.
Nel 5-10% della popolazione con psoriasi può insorgere l’Artrite Psoriatica (AP). L’Artrite Psoriatica è una malattia cronica caratterizzata da artrite infiammatoria associata con psoriasi.
Lo scopo di questo lavoro è sottolineare l’importanza dell’odontoiatra nel contribuire a una diagnosi precoce di Artrite Psoriasica, evitando e prevenendo lo sviluppo di complicazioni.
Materiali e Metodi: L’Artrite Psoriasica è una malattia cronica difficile da diagnosticare. La diagnosi viene fatta su sintomi clinici basati su caratteristiche di psoriasi ed artrite infiammatoria delle articolazioni. Molti reports descrivono gli effetti lesivi dell’AP sull’articolazione temporomandibolare (ATM), ma nessuno studio ha chiaramente evidenziato come l’ATM possa essere la prima articolazione coinvolta dalla AP. Questo lavoro riporta un caso di AP che era stato diagnosticato parecchi anni dopo l’esordio del danno temporomandibolare perchè nessun segno a parte la psoriasi era presente. La mancata precoce diagnosi risulta in un severo danno articolare.
Risultati: L’ATM può essere la prima articolazione coinvolta nell’AP. E’ spesso monolaterale, con esordio improvviso. Sul viso si osserva una netta asimmetria. I sintomi includono dolore e affaticamento dell’area articolare e dei muscoli masticatori, rigidità mattutina, crepitazione articolare, occasionale gonfiore doloroso della capsula articolare.
Conclusioni: Per una corretta diagnosi di AP, è fondamentale pertanto che esista sempre uno stretto rapporto interdisciplinare. Il dentista dovrebbe raccomandare inoltre esercizi miofunzionali e trattamento locale del dolore, uno splint occlusale per permettere all’ATM di lavorare correttamente. Tutto ciò permette di prevenire un ulteriore severo danno temporomandibolare e quindi di prevenire una conseguente asimmetria del volto.Aims: Psoriasis is a common inflammatory skin disease whose characteristic lesion is a patch very demarcated and covered with silvery scales.
In 5-10% of people with psoriasis Psoriatic Arthritis (PA) occurs. PA is a chronic disease characterized by inflammatory arthritis associated with psoriasis. The aim is to underline the importance of the dentist in the contribution to the early diagnosis of Psoriatic Arthritis, avoiding and preventing the complications.
Materials and Methods: Psoriatic Arthritis (PA) is a chronic systemic disease that is difficult to detect. The diagnosis is made mainly on clinical grounds based on the findings of psoriasis and inflammatory arthritis of the joints. Many reports have described the damaging effects of PA on the temporomandibular joints (TMJs), but no study has clearly reported the TMJ as the first articulation to be involved in PA. This work reports a case of PA that was diagnosed several years after a TMJ onset because no other signs apart from psoriasis were present. The missed early diagnosis resulted in severe articular damage.
Results: The TMJ can be the first joint involved in PA. It is often unilateral, with a sudden onset. The face has a clean asymmetry. Symptoms include pain and tenderness of the joint area and the muscles of mastication, morning stiffness, joint crepitation, occasional painful swelling of the TMJ capsule.
Conclusions: For a correct early diagnosis of PA, interdisciplinary collaboration it is very important. The dentist should recommend in addition to exercise and local pain treatment, an occlusal splint to help keep the TMJs working properly. All that allows to prevent further severe TMJ damage and, thus, to prevent subsequent facial asymmetr
Inestetismi dentofacciali in pazienti affetti da artrite giovanile : diagnosi volumetrica tridimensionale
No full textScopo del lavoro: L’Artrite Idiopatica Giovanile (AIG) può provocare nei bambini un danno all’articolazione temporomandibolare (A.T.M.) con alterazioni della crescita e dello sviluppo facciale. Il danno articolare provoca una maggiore convessità facciale anteriore, un aumento dell’altezza facciale anteriore rispetto all’altezza facciale posteriore, volti piccoli e corti com mandibole sottosviluppate.
Lo scopo di questo lavoro è mostrare l’importanza della Cone Beam Computerized Tomography (CBCT) per quantificare volumetricamente il danno dell’ ATM in pazienti affetti da AIG, misurando i reali volumi condilari e mandibolari.
Materiali e metodi: 34 bambini con AIG che presentavano un interessamento delle ATM sono stati sottoposti a Cone Beam Computerized Tomography. 4 sono stati esclusi perché le TC erano di difficile lettura.
La mandibola è stata isolata dalle altre strutture craniofacciali; l’intero volume mandibolare e i volumi delle sue parti (condilo, ramo, emimandibola, emisinfisi del lato destro e del lato sinistro) sono stati calcolati mediante misurazione tridimensionale del volume.
Risultati: I risultati hanno dimostrato una differenza statisticamente significativa tra i valori volumetrici della parte affetta rispetto a quelli della parte sana a livello condilare (p < 0.001), e i volumi dell’emimandibola, del ramo e dell’emisinfisi differiscono significativamente (p<0,01); mentre non c’erano grosse differenze nel volume dell’emicorpo. I dati non hanno evidenziato nessuna differenza tra la parte destra e quella sinistra. Nei maschi, la sola differenza significativa nel volume era tra condili sani ed affetti (p = 0.002). Questo è probabilmente dovuto al piccolo campione (n = 7). Nelle femmine, c’erano significative differenze nel volume di condilo, ramo ed emimandibola; non c’erano differenze per l’emicorpo.
Conclusioni: La Cone Beam Computerized Tomography rappresenta un importante miglioramento nella conoscenza dei cambiamenti morfologici del condilo e della mandibola, anche negli stadi precoci dell’AIG. Con una diagnosi precoce è, infatti, possibile intervenire prima che la malattia abbia causato deformazioni del volto.Dentofacial beauty flaws in patients with in Juvenile Arthritis: three-dimensional volumetric diagnosis.
Objective: The Juvenile Idiopathic Arthritis (JIA) can lead in children to temporomandibular joint damage with facial development and growth alterations. The articular damage causes an increased
Anterior facial convexity, an increase of anterior facial height in comparison to posterior facial height, small and short fces with underdeveloped mandibles. The aim of this study is to show the importance of Cone Beam Computerized Tomography to volumetrically quantify TMJ damage in patients with JIA, measuring condylar and mandibular real volumes.
Material and Methods: 34 children with temporomandibular involvement by JIA were observed by Cone Beam Computerized Tomography. 4 were excluded because of several imaging noises. The mandible was isolated from others craniofacial structures; the whole mandibular volume and its components’ volumes (condyle, ramus, emibody, emisymphysis on right side and on left side) has been calculated by a 3D volume rendering technique.
Results: The results show a very significant difference in volume between the healthy and affected condyles (p < 0.001), and the volumes of the hemimandible, ramus, and hemisymphysis differed significantly (P<0,01); however, there was no difference in volume between the hemibodies. The data didn’t show any statistical differences between right side versus left side. In males, the only significant difference in volume was that between the healthy and affected condyles (p = 0.002). This was probably due to the small sample size (n = 7). In females, there were significant differences in volume for the condyle, ramus and hemimandible, and ramus; no differences for the hemibody.
Conclusion: The Cone Beam Computerized Tomography represents a huge improvement in understanding of the condyle and mandibular morphological changes, even in the early stages of the Juvenile Idiopathic Arthritis. Therefore, by early diagnosis, it is possible to operate before the disease has caused face deformities
3D quantitative measurement of condylar morphological changes in osteoarthritis : statistical stand point
No full textAim: The aim of this study was to evaluate from a statistical stand point the temporal, metric and clinical variables of the disease in order to plan an effective therapy for primary and secondary prevention, the ultimate purpose being to limit the erosive effects on mandibular condyles, allowing an harmonious dental and bone development of the patients affected by JIA.
Materials and Methods: This study enrolled 30 patients with JIA. CBCT has been performed. 3D quantitative measures of the mid-lateral and anterior-posterior diameters and angles of the condyles were taken. The data were captured using an I-CATTM cone beam 3-D imaging system and processed using I-CAT Vision viewing software, which allows visualization and measurement of the images in three dimensions (3D). Averages, standard deviations and 95% confidence intervals (CI) of the temporal, metric and clinical variables available were performed.

The average right angle was 33° and the average left angle was 36°. There was a very significant difference in the linear and angular measurements between healthy and affected condyles (p<0.01).
Discussion: The use of CBCT and the 3D diagnostic protocol in young patients with JIA enabled reliable, accurate, and precise quantitative and images of the condylar structures and their dimensional relationships. In patients with JIA, temporomandibular joint involvement is often asymptomatic and can lead to severe craniofacial growth disturbances and facial deformities if not treated in the initial stage. TMJ arthritis in JIA patients is difficult to diagnose at an early stage, as there are relatively few symptoms and clinical findings. The pathological process can affect growth long before radiographic changes are seen. None of the clinical signs or symptoms of TMJ dysfunction are predictors of bony destruction of the TMJ.
Conclusions: CBCT provides useful information to supplement clinical and laboratory examinations in the diagnosis and treatment of JIA. Patients with CBCT evidence of TMJ damage cannot be identified reliably by clinical examinations. CBCT represents an improvement in quantifying the morphological changes of the condyle and mandible. Furthermore, it gives an accurate picture of these structures in JIA and allows the acquisition of true measurements of the mandibular components
Psoriatic arthritis: temporomandibular joint involvement as the first articular phenomenon
No full textPsoriatic arthritis (PA) is a chronic systemic disease that is difficult to detect. The diagnosis is made on mainly clinical grounds based on the findings of psoriasis and inflammatory arthritis of the joints. Many reports have described the damaging effects of PA on the temporomandibular joints (TMJs), but no study has clearly reported the TMJ as the first articulation to be involved in PA. This article reports a case of PA that was diagnosed several years after TMD onset because no signs besides psoriasis were present. The missed early diagnosis resulted in severe TMJ damage. The TMJ can be the first joint involved in PA. For a correct, early diagnosis of PA, collaboration between dental clinicians and rheumatologists is very important
Stress fractures of the base of the metatarsal bones in young trainee ballet dancers
No full textClassical ballet is an art form requiring extraordinary physical activity, characterised by rigorous training. These can lead to many overuse injuries arising from repetitive minor trauma. The purpose of this paper is to report our experience in the diagnosis and treatment of stress fractures at the base of the second and third metatarsal bones in young ballet dancers. We considered 150 trainee ballet dancers from the Ballet Schools of "Teatro Alla Scala" of Milan from 2005 to 2007. Nineteen of them presented with stress fractures of the base of the metatarsal bones. We treated 18 dancers with external shockwave therapy (ESWT) and one with pulsed electromagnetic fields (EMF) and low-intensity ultrasound (US); all patients were recommended rest. In all cases good results were obtained. The best approach to metatarsal stress fractures is to diagnose them early through clinical examination and then through X-ray and MRI. ESWT gave good results, with a relatively short time of rest from the patients' activities and a return to dancing without pain
Condylar osteophytic neoformation in TMJ arthritis : CBCT vs conventional Rx
No full textAim: The purpose of this work was to show the role of CBCT versus conventional radiographs for accurate and reliable detection of osteophytic neoformations on mandibular condyle in Juvenile Idiopathic Arthritis (JIA).
Materials and Methods: An unusual case report was reported. A 16 years old girl was affected by JIA since 8 year of age. When she was 12 year old, came to our observation severed by rheumatologist and orthodontic treatment was proposed to patient to avoid and prevent the TMJ complications CBCT imaging has been performed and the left condyle demonstrated the bird-beak appearance with a large osteophyte. Osteophyte is the medical term for the overgrowth of bone tissue more commonly called ‘bone spurs’. Despite the term ‘spur’, osteophytes are actually small round lumps of extra bone that grow around joints. Osteophytes are the body’s attempt to compensate for existing bone and ligament degeneration due to age arthritis or injury. Unfortunately, the body’s attempt to heal itself this way is unsuccessful.
Results: The CBCT showed mandibular condyle’s morphological and surface changes as cortical erosion, flattening, sclerosis, osteophyte neoformation and a reduced inter-articular space.
Discussion: JIA is a common disease of childhood that causes joint inflammation, typically before 16 years of age. When the TMJ is affected, there is often no pain, which delays the diagnosis and treatment. The condylar abnormalities can range from slight erosion and flattining of the articular surfaces to severe destruction of the conyle head or osteophytic neoformations. Osteophytes are formed by the body for the purpose of limiting or stopping motion in a deteriorating joint that becomes too loose. Since degenerative joint conditions are characteristic of athletes and the aged, osteophytes are common in those with sports related injuries or arthritis.
Conclusions: CBCT represents an improvement in quantifying the morphological changes of the condyle and mandible. The accurate and early diagnosis of JIA and the sensitive monitoring of the disease process are essential. Advanced imaging technology capable of identifying even the slightest trace of erosive joint damage may enable the prediction of future structural and functional deterioration
Stabilographical and electromyographical assessments in TMD patients
No full textAim: The purpose of this investigation was to show how the stabilograph, the electromyograph and the kinesiograph help to diagnose and treat postural problems, masticatory muscle pains and temporomandibular joint disorders.
Materials and Methods: A group of 52 patients with malocclusions and craniomandibular disorders symptomatic at the time of examination was compared to 40 previously studied healthy subjects.
TMD is a collective term embracing a number of clinical problems that involve the masticatory musculature and the temporomandibular joints. All TMD patients and controls were evaluated using stabilograph, electromyograph and kinesiograph.
Results: TMD patients have distinctly different patterns of muscle activity than asymptomatic subjects. Besides restrictions, deviations, limitations in jaw movement are important diagnostic criteria.
Discussion: Successful treatment reduces the irregularity and severity of muscle dysfunction and improves the mandibular movements and organismic posture. So comparison of post-treatment results with pre-treatment situations documents treatment efficacy and effectiveness.
Conclusions: The complex etiology of TMD requires an interdisciplinary approach for successful diagnosis, treatment and maintenance. These instrumentations (EMG-CMS and stabilograph) are extremely valuable for initial patient evaluations, as well as for monitoring treatment results
Laboratory and industrial testing of silica bricks for coke ovens
Get PDFIn order to rationalize the reconstruction of coke ovens' walls in a local steelmaking, a set of laboratory and industrial tests was carried out on silica KN bricks. Two types of bricks that are currently used in oven construction were analyzed, one being less expensive than the other. On the other hand, 25 year-old original bricks were also studied. The results of laboratory tests were analyzed taking into account the requirements of DIN 1089 standard. Additionally, an evaluation of costs was carried out.Fil: Camerucci, Maria Andrea.
