          SUMMARY

          The ratio of bad habits, mouth breathing and malocclusion is an important issue in view of prevention and early treatment of disorders of the craniofacial growth. While bad habits can interfere with the position of the teeth and normal pattern of skeletal growth, on the other hand obstruction of the upper airway, resulting in mouth breathing, changes the pattern of craniofacial growth causing malocclusion. Our crosssectional study, carried out on 3017 children using the ROMA index, was developed to verify if there was a significant correlation between bad habits/mouth breathing and malocclusion. The results showed that an increase in the degree of the index increases the prevalence of bad habits and mouth breathing, meaning that these factors are associated with more severe malocclusions. Moreover, we found a significant association of bad habits with increased overjet and openbite, while no association was found with crossbite. Additionally, we found that mouth breathing is closely related to increased overjet, reduced overjet, anterior or posterior crossbite, openbite and displacement of contact points. Therefore, it is necessary to intervene early on these aetiological factors of malocclusion to prevent its development or worsening and, if already developed, correct it by early orthodontic treatment to promote eugnatic skeletal growth.

          RIASSUNTO

          Il rapporto fra abitudini viziate, respirazione orale e malocclusione è fondamentale in tema di prevenzione e trattamento precoce dei disturbi della crescita cranio-facciale. Infatti così come le abitudini viziate possono interferire negativamente con la posizione dei denti e con il normale pattern di crescita scheletrica cranio-facciale, così l'ostruzione delle vie aeree superiori, con conseguente respirazione orale, cambia il modello di crescita craniofacciale con sviluppo di malocclusioni da moderate a severe. Questo studio trasversale, effettuato su 3.017 bambini applicando il ROMA index, vuole verificare l'esistenza di una correlazione significativa tra abitudini viziate/respirazione orale e malocclusione. Dai risultati emerge che all'aumentare del grado dell'indice aumenta anche la prevalenza di abitudini viziate e respirazione orale, significando che questi fattori sono associati alle malocclusioni più gravi. Inoltre abbiamo riscontrato un'associazione statisticamente significativa fra abitudini viziate e overjet e openbite aumentati, ma non con il morso inverso. Dal lavoro è emerso che la respirazione orale è strettamente correlata ad overjet aumentato, overjet inverso, morso crociato, openbite e displacement. Riteniamo quindi che abitudini viziate e respirazione orale, rientrando fra i fattori di rischio di malocclusione, vadano intercettati e corretti precocemente per prevenire lo sviluppo di malocclusioni o il peggioramento di quelle preesistenti.

          The development of an index of orthodontic treatment priority.

          P Brook, W Shaw (1989)
          The aim of this study was to develop a valid and reproducible index of orthodontic treatment priority. After reviewing the available literature, it was felt that this could be best achieved by using two separate components to record firstly the dental health and functional indications for treatment, and secondly the aesthetic impairment caused by the malocclusion. A modification of the index used by the Swedish Dental Health Board was used to record the need for orthodontic treatment on dental health and functional grounds. This index was modified by defining five grades, with precise dividing lines between each grade. An illustrated 10-point scale was used to assess independently the aesthetic treatment need of the patients. This scale was constructed using dental photographs of 12-year-olds collected during a large multi-disciplinary survey. Six non-dental judges rated these photographs on a visual analogue scale, and at equal intervals along the judged range, representative photographs were chosen. To test the index in use, two sample populations were defined; a group of patients referred for treatment, and a random sample of 11-12-year-old schoolchildren. Both samples were examined using the index and satisfactory levels of intra- and inter-examiner agreement were obtained.

            The effect of mouth breathing versus nasal breathing on dentofacial and craniofacial development in orthodontic patients.

            To determine the effect of mouth breathing during childhood on craniofacial and dentofacial development compared to nasal breathing in malocclusion patients treated in the orthodontic clinic. Retrospective study in a tertiary medical center. Clinical variables and cephalometric parameters of 116 pediatric patients who had undergone orthodontic treatment were reviewed. The study group included 55 pediatric patients who suffered from symptoms and signs of nasal obstruction, and the control group included 61 patients who were normal nasal breathers. Mouth breathers demonstrated considerable backward and downward rotation of the mandible, increased overjet, increase in the mandible plane angle, a higher palatal plane, and narrowing of both upper and lower arches at the level of canines and first molars compared to the nasal breathers group. The prevalence of a posterior cross bite was significantly more frequent in the mouth breathers group (49%) than nose breathers (26%), (P = .006). Abnormal lip-to-tongue anterior oral seal was significantly more frequent in the mouth breathers group (56%) than in the nose breathers group (30%) (P = .05). Naso-respiratory obstruction with mouth breathing during critical growth periods in children has a higher tendency for clockwise rotation of the growing mandible, with a disproportionate increase in anterior lower vertical face height and decreased posterior facial height.

              Primate experiments on oral respiration.

              Oral respiration associated with obstruction of the nasal airway is a common finding among patients seeking orthodontic treatment. The primate experiments reported here are part of a series designed to test some of the current hypotheses regarding the relationship between mouth breathing and dental malocclusions, that is, between deviations in orofacial muscle recruitment and jaw morphogenesis. Mouth-breathing was developed in the animals of this experiment by obstruction of the nasal passages with silicon nose plugs. The experiments showed that the monkeys adapted to nasal obstruction in different ways. In general, the experimental animals maintained an open mouth. Some increased the oral airway rhythmically, while others maintained the mandible in a lower position with or without protruding the tongue. All experimental animals gradually acquired a facial appearance and dental occlusion different from those of the control animals. From these and the previously reported primate experiments in this laboratory, it can be deduced that orthodontic appliances in general affect the morphology of the orofacial structure in two ways: by direct force and by sensory stimulation. (1) The appliance exerts a direct physical force which alters the strain distribution in the bone and elicits bone remodeling and tooth movement. (2) The presence of the appliance initiates the sensory input which triggers a neuromuscular response. This change in neuromuscular activity, in turn, affects both muscle development and bone remodeling. The fixed orthodontic appliance may work mainly on the first principle. Certain removable appliances may have a significant effect based on the second principle.
