“…22 Certain conditions, such as cleft of the soft palate, can have a profound effect on speech as the palate fails to create a posterior seal on phonation and air escapes up into the nose causing hypernasality of the speech. An ; 23 however with normal oral function, even in the presence of a malocclusion, there seems to be huge potential for compensation and there is little substantial evidence that orthodontic correction, even involving orthognathic surgery for severe skeletal discrepancies, will resolve articulatory problems without the adjunct of speech therapy. 24 It would seem, therefore, that the evidence supporting claims of significant dental health improvements following orthodontic treatment are tenuous; however it is increasingly recognised that the health of individuals should be defined, not only in terms of the presence and absence of physical disease and pathology, but more widely in terms of their psychological and social well-being.…”

What is the value of orthodontic treatment?

SummaryOrthodontic treatment is as popular as ever. Orthodontists frequently have long lists of people wanting treatment and the cost to the NHS in England was £261m in 2013-14 (approximately 11% of the NHS annual spend on dentistry). It is important that clinicians and healthcare commissioners constantly question the contribution of interventions towards improving the health of the population. In this article the authors outline some of the evidence for and against the claims that people with a malocclusion are at a disadvantage compared with those without a malocclusion and that orthodontic treatment has significant health benefits. The authors would like to point out that this is not a comprehensive and systematic review of the entire scientific literature. Rather the evidence is presented in order to stimulate discussion and debate.

“…This affects the craniofacial development and cause deviations of the dental occlusion with a significantly more open intermaxillary jaw relationship, retrognathic inclined mandible, lateral cross-bite and narrower inter-canine width when compared to healthy controls (Behlfelt, LinderAronsson, McWilliam, Neander, and Laage-Hellman, 1990;Lofstrand-Tidestrom, Thilander, Ahlqvist-Rastad, Jakobsson, and Hultcrantz, 1999). In a recent study from Finland the prevalence of Class II or asymmetric malocclusion in children with sleep-disordered breathing was 33% (Pirilä-Parkkinen, Pirttiniemi, Nieminen, Tolonen, Pelttari, and Löppönen, 2009) An open-bite may cause distortions of the s-sound normally produced by the tip of tongue in the dentoalveolar region (Laine, 1987). Normal /s/ is produced by many individuals with a low tongue tip and the tongue blade at the site of maximum contriction which is consistently in the region mentioned.…”

Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess sarticulation, perceptually and acoustically in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, 50-65 months, on waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected pre-operatively and six months post-operatively. Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls. After surgery /s/-articulation was normalized perceptually, but acoustic differences still remained. No significant differences between surgical methods were found..

“…4 However, speech disorders have been reported to be associated to different malocclusions, such as: Class II molars, 5,6 Class III molars, 7,8 deep overbite 9,10 and open bite, 7,11,12 the latter being the one that leads more frequently to speech disorders, as researchers have noticed a close relation between open bite and anterior lisping. 7,8,12,13 As epidemiological studies demonstrate that malocclusions occur, on average, in 50% of the population, 14,15 and since occlusal disharmony predisposes to phonoarticulatory alterations, consequently the latter will occur very frequently. Some authors also emphasize that children with pre-existing speech disorders may have their difficulties accentuated by the presence of dental malocclusion.…”

Through a transversal epidemiological study, conducted with 333 Brazilian children, males (157) and females (176), aged 3 to 6 years old, enrolled in a public preschool, this study aimed to evaluate the prevalence of the different types of vertical interincisal trespass (VIT) and the relationship between these occlusal aspects and anterior lisping and/or anterior tongue thrust in the articulation of the lingua-alveolar phonemes /t/, /d/, /n/ and /l/. All children involved were submitted to a VIT examination and to a speech evaluation. Statistical significance was analyzed through the Qui-square test, at a significance level of 0.05 (95% confidence limit). The quantitative analysis of the data demonstrated the following prevalences: 1 -the different types of VIT: 48.3% for normal overbite (NO), 22.5% for deep overbite (DO), 9.3% for edge to edge (ETE) and 19.8% for open bite (OB); 2 -interdental lisping in relation to the different types of VIT: 42% for NO, 12.5% for DO, 12.5% for ETE, 32.9% for OB; and 3 -children with anterior tongue thrust in the articulation of lingua-alveolar phonemes in relation to the different types of VIT: 42.1% for NO, 14% for DO, 10.5% for ETE, 33.3% for OB. The results demonstrated that there was a significant relationship between open bite and anterior lisping and/or anterior tongue thrust in the articulation of the lingua-alveolar phonemes /t/, /d/, /n/ and /l/; and that there was a significant relationship between deep overbite and the absence of anterior lisping and anterior tongue thrust in the articulation of the lingua-alveolar phonemes.
