ABSTRACT Purpose To ascertain primary and secondary school teachers knowledge of mouth breathing, as well as to gauge teachers improvements in knowledge of the subject area after the speech therapy guidance program. Methods 150 teachers from both public and private schools participated in the program. The promotion of information about mouth breathing was carried out as part of the Speech Therapy Program, which addressed areas such as the physiology of breathing, causes and consequences of mouth breathing and the professionals involved in the treatment. Before and after the program semi-structured questionnaires were given out, the questionnaires contained objective and discursive questions about the causes and consequences of mouth breathing. The McNemar test was used for statistical analysis of the pre and post program questionnaires. The comparison between the general average of correct answers was ascertained by using the t-Student test. All differences were considered statistically significant at a significance level of 5%. Results Statistical differences (p<0.05) were found in all questions in the pre and post-orientation program questionnaires. Conclusion The teachers showed they had some previous knowledge about mouth breathing, however the Speech Therapy Orientation Program proved to be effective and resulted in the teachers showing a greatly increased knowledge about the subject.

Timetable for oral prevention in childhood--developing dentition and oral habits: a current opinion.

As most of the etiologic factors of malocclusion are of genetic origin and thus cannot be prevented, environmental causative factors have become the focus for correction. Early interception of oral habits may be an important step in order to prevent occlusal disturbances in children. The identification of an abnormal habit and the assessment of its potential immediate and long-term effects on the dentition and potentially on the craniofacial complex should be made at an early stage. This paper focuses on the most common oral habits influencing dentofacial growth in childhood and management of these habits in the developing dentition.

Novel porous oral patches for patients with mild obstructive sleep apnea and mouth breathing: a pilot study.

OBJECTIVES: Habitual open-mouth breathing (OMB) during sleep can cause snoring and obstructive sleep apnea (OSA). This study used a porous oral patch (POP) to treat patients with mild OSA and OMB during sleep. The subjective and objective outcomes were evaluated. STUDY DESIGN: Prospective study. SETTING: Tertiary referral center. SUBJECTS AND METHODS: Patients with ≥5 events hourly but <15 hourly on the apnea-hypopnea index (AHI) were enrolled. All patients slept with their mouths closed by using the POP, which is a porous skin pad consisting of 3 layers: silicone sheet, polyurethane foam, and polyurethane film. Before treatment and during treatment, subjective outcomes were assessed using the Epworth Sleepiness Scale (ESS) and visual analog scale (VAS) of snoring. Objective outcomes were assessed using polysomnography and cephalometry. RESULTS: Thirty patients were enrolled in this study. All patients slept with their mouths closed while using a POP. The ESS and VAS of snoring scores were 8.1 ± 1.5 and 7.5 ± 2.0 before the POP, respectively, in contrast to 5.2 ± 1.6 and 2.4 ± 1.4 while using a POP, respectively (P < .05). The median AHI score was significantly decreased by using a POP from 12.0 per hour before treatment to 7.8 per hour during treatment (P < .01). The snoring intensity and median snoring index were 49.1 ± 10.8 dB and 146.7 per hour before the POP, respectively, which decreased to 41.1 ± 7.8 dB and 40.0 per hour while using a POP, respectively (P < .01). Cephalometry revealed that the retropalatal space and retrolingual space were 7.4 ± 1.6 mm and 6.8 ± 2.5 mm before the POP, respectively, compared with 8.6 ± 1.2 mm and 10.2 ± 1.8 mm during treatment, respectively (P < .01). CONCLUSION: The POP is a useful device to treat patients with mild OSA and habitual OMB.

Compensatory orthodontic treatment for maxillary deficiency: a 4-year follow-up.

In this article, we report the orthodontic treatment of a boy (age 12 years 9 months) who had a midface deficiency, a concave facial profile with maxillary retrusion, a complete crossbite (anterior and posterior), and the maxillary right canine retained in the alveolus. Rapid maxillary expansion was performed followed by complete orthodontic treatment with fixed appliances combined with Class III elastics and anterior vertical elastics. Time was allowed to elapse until growth was virtually over before removing the fixed appliances (at age 18 years 4 months), and no retainer of any type was used. As a result of treatment, significant improvement was noted in his facial appearance, with a proper maxillomandibular relationship, total correction of the maxillary atresia, and satisfactory overjet and overbite. The results remained stable at the 4-year follow-up. Therefore, it can be argued that the use of Class III elastics combined with rapid maxillary expansion has a beneficial effect in the treatment of transverse and sagittal maxillary deficiency in growing patients. Excellence in how the treatment was finished and discontinuation of treatment and control in the final stages of growth contributed to the stability of the final results.

The Loudon Chateau repositioning appliance.

The LCR Appliance if fabricated and used properly, has many advantages over the Herbst and Twin Block appliances in solving tongue thrust, mandibular deficiency and repositioning with proper mandibular advancement and mandibular growth results. The regular Chateau appliance was named in 1904 after Dr. Chateau in Franc. It was originally used in Europe but was an uncomfortable removable appliance with wires used in the mandibular anterior lingual area to reposition the mandible.

Influencia del tratamiento con aparatología ortopédico-funcional sobre la luz del rinofaringe / Influence of the functional-orthopedic appliances treatment on rhino-pharynx patency

Es por todos conocido que la respiración bucal juega un papel de suma importancia en la aparición de las disgnacias en edades tempranas. Con el objetivo de determinar qué tratamiento resulta más adecuado en relación a un enfoque etiopatogénico y comparar los resultados obtenidos, se realizó el siguiente trabajo. La muestra estuvo formada por 36 pacientes disgnácicos, entre 4 y 14 años, divididos en tres grupos. Grupo A: sin tratamiento (grupo control), formado por 15 pacientes (41,66 por ciento); grupo B: tratado con ortopedia funcional, formado por 14 pacientes (38,88 por ciento); grupo C: tratado con ortodoncia, formado por 7 pacientes (19,44 por ciento). Todos ellos fueron elegidos al azar. Se midió la luz de la vía aérea superior, sobre calcos de tele-Rx de cabeza de perfil, tomadas con un intervalo no menor a 10 meses, en la ciudad de La Plata, capital de la prov. de Buenos Aires, y en la ciudad de Neuquén, capital de la prov. de Neuquén, República Argentina, en un universo constituido por 2500 pacientes. Para realizar las mediciones, se utilizaron cinco parámetros del cefalograma faríngeo, observándose que en el grupo A hubo una disminución promedio de -0,49mm. Si consideramos la evolución de este grupo control como referencia, podemos decir que hubo aumento de la luz faríngea en todos los pacientes tratados: en el grupo B de un 100 por ciento (1.49mm) y en el grupo C de 75 por ciento (0.99mm). Como conclusión evidente, los pacientes tratados con ortopedia funcional fueron los que alcanzaron mayor aumento de la luz de la vía aérea superior.

The airway, breathing and orthodontics.

Dentists need to play a bigger role in managing airway development and craniofacial formation even though the relationship between the airway, breathing and malocclusion remains quite controversial. Certainly the airway, the mode of breathing and craniofacial formation are so interrelated during growth and development that form can follow function and function can follow form. So, it is imperative to normalize form and function as early as possible so that function is optimized for life.

Fatores associados ao surgimento da respiração bucal nos primeiros meses do desenvolvimento infantil / Factors associated with onset of mouth breathing in early child development

OBJETIVO: os problemas relacionados com a respiração bucal são vários e possuem diversas consequências na saúde humana. O estudo de coorte prospectiva se propõe a determinar os fatores de risco associados ao desenvolvimento da respiração bucal nos primeiros períodos do desenvolvimento infantil. MÉTODO: o grupo inicial constituiu-se por 86 bebês com idade de zero a três meses selecionados em áreas de abrangência do município de Vitória-ES. Realizaram-se sete visitas domiciliares, coletando-se dados sobre respiração bucal, mista, vedamento labial, alterações respiratórias intervisitas, estimulação da respiração nasal, ronco habitual ao dormir, uso de mamadeira, sucção de chupeta, sucção de dedo e aleitamento materno. A partir do grupo inicial, 67 crianças permaneceram em acompanhamento até a idade média de 29,42 meses (+ 2,49dp). RESULTADOS: a prevalência de respiração bucal foi de 3,0 por cento. O aleitamento materno (ORaj = 0,27 : 0,09 - 0,83) e a estimulação da respiração nasal (ORaj = 0,09 : 0,01 - 0,52) funcionam como fatores de proteção ao vedamento labial, enquanto a alteração respiratória intervisita (ORaj = 7,61 : 1,09 - 53,01), sucção de chupeta (ORaj = 5,54 : 2,00 - 15,37) e o ronco (ORaj = 10,74 : 2,32 - 49,64) funcionam com fatores de risco. CONCLUSÃO: a gênese da respiração bucal inicia-se pela perda do vedamento labial, como conseqüência da interação de fatores positivos e negativos sobre o complexo neurológico, ósseo e muscular.

Effect of mouth taping at night on asthma control--a randomised single-blind crossover study.

BACKGROUND: Nose breathing ensures that inspired air is warm, filtered and moist and may therefore benefit patients with asthma. It features in some complementary approaches to treat asthma and is encouraged at night in the Buteyko technique by the use of mouth taping. In this pragmatic study we sought to determine whether taping the mouth at night has any effect on asthma control compared with usual breathing in patients with symptomatic asthma, since if it was effective it would be a simple intervention to implement. METHODS: This was a randomised, single-blind, crossover study of participants (n=51) with symptomatic asthma (mean FEV(1) 86% predicted). A 4-week period of usual breathing at night was followed by use of mouth taping with microporous tape, as in the Buteyko technique, or vice versa, with a 2-week run-in period and a minimum 2-week washout period of usual breathing between 'treatments'. Primary outcomes were morning peak expiratory flow and symptom scores (Asthma Control Diary). Outcomes were measured and analysed without knowledge of treatment allocation. RESULTS: Fifty participants completed the study and reported taping their mouth for a median 26 of 28 nights. Although 36 participants said mouth taping was very or fairly acceptable there were no differences between treatments for morning peak expiratory flow (mean difference -1l/min (95%CI, -9 to 7)) or symptoms scores (mean difference -0.12 (95%CI, -0.30 to 0.06)) nor for any secondary measures. CONCLUSIONS: Taping the mouth at night had no effect on asthma control in patients with symptomatic asthma.

[A functional approach in the primary treatment of labial-alveolar-velopalatine clefts for a minimum of sequels]. / Une approche fonctionnelle lors du traitement primaire des fentes labioalvéolopalatovélaires pour le minimum de séquelles.

Is the poor potential of growth an ineluctable consequence of mesodermal deficiency? Should we agree with the idea that all protocols are equivalent? Actually, these opinions reflect the empiricism of previous generations. We must now become rational and develop a project without compromise to achieve good functions at primary surgery. 'The normal structures are present on either side of the cleft, only modified by the fact of the cleft...' Victor Veau's hypothesis is the conclusion of rigorous anatomical and embryological research. Our current knowledge of the pathological anatomy allows for a better restoration of the normal anatomy. Anatomy is nothing if it is not functional. Every thing should be done to control the healing process to allow the best expression and interaction of the various functions, especially for those concerning nasal ventilation and masticatory efficiency. To correct the deformity, the cleft surgeon must perform a wide subperiosteal and subperichondrial elevation and must learn the skills of this accurate work to preserve the integrity of very fragile structures. The primary treatment must take into account a rational and uncompromising selection of the age of the first operation, of the successive procedures, and their chronology to benefit from the growth spurt of the maxilla, and to avoid the worse scars resulting from secondary epithelialization. Finally, if nasal breathing is the most important function concerning facial growth, it is essential to restore this normal function at the time of the first operation. The oral breathing pattern set at the time of the first operation leaves a cortical imprint that is very difficult to erase, even after clearing the nasal airways. The results of the functional approach we have used in the last decade are particularly consistent and very convincing. In this ambitious and demanding program, the patient comes first; we decrease the burden for him and his family, and give them the benefit of a good social life before school age.

Care of nasal airway to prevent orthodontic problems in children.

Obstruction in the upper respiratory passage is a cause of mouth breathing. A mouth breather lowers the tongue position to facilitate the flow of air in to the expanding lungs. The state of equilibrium of forces inside themouth is disturbed, thereby resulting altered soft tissue force acting on the bones in between. The resultant effect is maldevelopment of the jaw in particular and deformity of the face in general. Setting of the teeth on the jaw is also affected. All these make the face to look negative. So, to prevent orthodontic problem in children, it is necessary to detect the nasopharyngeal obstruction and treat the same accordingly.

[Influence of feeding method on maxillofacial development]. / Influence de l'allaitement sur le développement maxillo-facial.

The functional differences between breast-feeding and bottle-feeding may have a significant effect on dento-facial development and on the genesis of some severe malocclusions. Orthodontists should be aware of this sometimes under-estimated aspect of development. They should, in conformity with their role as professional health care providers, advise long-term breast feeding as a way of preventing certain disorders or, at least, reducing their severity.

Acoustic rhinometric measurements in children undergoing rapid maxillary expansion.

OBJECTIVE: To evaluate geometric changes of nasal cavities in children undergoing rapid maxillary expansion and to assess the effect of this procedure on nasal airway size by means of acoustic rhinometry. METHOD: We recruited 14 mouth-breather children (mean age 8.2 years) presenting constricted maxillary arches and scheduled for rapid maxillary expansion in the orthodontics department of our hospital. Clinical history did not reveal any allergic diseases and ENT examination was completely normal with a well-aligned nasal septum. Nasal measurements were obtained using acoustic rhinometry, which was performed before the expansion treatment and after 1-year follow-up. A postero-anterior radiograph of the skull was also performed in all patients for cephalometric analysis before and 3 months after the treatment. RESULTS: We observed a satisfactory increment in the transverse dimension of the maxilla in all patients but one who manifested a relapse after 4 months from the treatment and required a second procedure. Similarly, acoustic rhinometric measurements and cephalometric tracings showed a statistically significant increase respectively in decongested total nasal volumes (p=0.047) and in binasal cavity width (p=0.001). However, only eight children switched their respiration from oral to nasal breathing mode. CONCLUSIONS: Rapid maxillary expansion is an effective method for increasing the width of narrow maxillary vault and it is also associated with a significant increment in nasal volumes and in the transverse diameter of the maxilla. With regard to breathing posture, the role of this procedure still remains debatable. To date this is the first study aimed at analysing the effects of rapid maxillary expansion on nasal dimensions by means of acoustic rhinometry.

Clinical study on the use of nozovent in a tertiary care setting.

OBJECTIVE: To assess the effectiveness of the Nozovent device in Pakistani subjects at Aga Khan University Hospital, Karachi and Sir Ganga Ram Hospital, Lahore from 15 January 2001 to 15 January 2002. METHODS: Sixty males and 40 females were selected by non probability purposive sampling, from OPD of ENT Department, complaining of nasal obstruction due to various reasons, e.g. vasomotor rhinitis, allergic rhinitis, congestion during pregnancy and menstruation, common cold, traumatic nose and nasal valve problem. RESULTS: All patients benefited subjectively but the degree of relief varied in individuals. CONCLUSION: The Nozovent provides a unique method to relieve nasal obstruction with no side effects.

Impact of nasal airway obstruction on dentofacial development and sleep disturbances in children: preliminary notes.

Respiratory disorders in the upper respiratory tract during sleep are most often part of a continuous pathological process of long standing. Schematically, three clinical syndromes with increasing severity are described: breathing with the mouth open, snoring and sleep apneal hypopnea syndrome. Obstructive sleep apnea syndrome (OSAS) is a subtle, but severe sleep disorder of early childhood. It is often difficult to detect and may have long-term consequences, including failure to thrive, behavioral disturbances, developmental delay, and cor pulmonale. These conditions always include a functional maxillofacial perturbation, which may be associated with a constitutional or acquired morphological disorder. Pediatric dentists must be aware of the problems connected with mouth breathing and OSAS (obstructive sleep apnea syndrome) in children as any delay in diagnosis and treatment may cause prolonged morbidity. They also have a role in the diagnosis and co-management of these patients because the signs and symptoms may be recognizable in the dental practice. Besides the medical approach itself, the treatment sometimes is surgical, always orthopedic: the earlier it is initiated, the more effective, simple and unrestraining it is. The aim of this work is to focus attention on the early diagnosis and prevention of these pathologies. Diagnostic guidelines will be illustrated.

The effect of external nasal dilators on blood oxygen levels in dental patients.

UNLABELLED: BACKGROUND. The authors conducted a study to examine the use of external nasal dilators, or ENDs, on dental patients and to determine whether the subjective improvement in comfort level noted in dental patients using ENDs is accompanied by a rise in the level of oxygen saturation as measured by pulse oximetry, or SpO2. METHODS: The authors used a hand-held pulse oximeter to monitor 45 patients' SpO2 levels during routine dental procedures. RESULTS: The data suggest that dental procedures in general result in a lowering of the SpO2 level and that patients using an END do experience a rise in the SpO2 level. CONCLUSIONS: The data do not clearly establish that the increase in patient comfort with use of an END is due to a rise in the SpO2 level. CLINICAL IMPLICATIONS: The results of this study demonstrate that the use of an END facilitates nasal breathing in dental patients.
