about NHS band/UDA

[Guest guest]

Hi All,

this question is commonly seen in MJDF,

A root canal treatment is done on child patient then after 3 months a crown is put on the same tooth,which band is the treatment and how many UDAs will dentist get?

A patient with 9mm overjet,needs ortho treatment,which band of treatment will this fall in?

3)antifungal which should not be given with diazepam

4)Fl varnish which aggrevates ANUG.

Thank you.

hese phonetics are in relation to complete denture phonetics. .. i have pasted a material i came across... hope this helps....

correct me if i am wrong...

Mechanism of speech The voice is produced in the larynx: the muscles of the thorax and abdomen control the flow of the air with nasal cavity act as resonant chamber  The air from the larynx divided into 2 streams by the velum:a) Upper stream: the air expelled entirely through the nose to produce the nasal sounds: N-M-Ng. Lower stream: the air expelled through the oral cavity and altered by the palate, tongue and position of the teeth and lips to produce all other sounds. Types of sound:I. Vowels:  Produced by vibration of the vocal cords and not affected by oral structures. The tongue is positioned in the floor of the mouth and contact lingual surface of anterior teeth.  Types: Vowels are: a-e-i-o-u.II.

Consonants:  Produced by constriction, obstruction and direction of the air stream when the air pass through the mouth  Types: a) According to the manner of production:1. Nasal sounds: N-M-Ng Produced through the nose. When the nasal cavity is blocked (adenoid hypertrophy- deviated nasal septum), hypernasality occurs.2. Plosives sounds: P-B-T-D-K Produced by complete stop of air stream, build up of pressure in the oral cavity then sudden release and explosion of air3. Sibilant (fricative) sounds: S-Ch-H-X-Z Produced by friction of the air stream when forced through narrow path wayb) According to the site of production:1. Bilabial sounds: B-P-M Formed by lip only. The air from the lung builds up pressure behind the closed lip, explosion produced when the lip suddenly opened2. Labiodentals sounds: F-V Formed by lips and teeth. Produced

by the contact between the upper incisors and the lower lip3. Lingudental sounds: Th Formed when the tip of the tongue is positioned between upper and lower incisors4. Lingualveolar sounds: a. Tongue and the anterior portion of the hard palate: S, T-D S: the tongue form a slit like channel into which the air hisses and the air escape from the median grove of the tongue when it is positioned behind maxillary incisors. If this groove is flattened, lisping occurs (S is pronounced Ch), and if the groove is deepened whistling occurs  T-D: the sided of the tongue contact the teeth, the air stops and sudden release (explode) b. Tongue and the intermediate portion of the hard palate: Sh-Ch-J The tongue is pressed against large area of the hard palate and alveolar processc. Back of the tongue and soft palate: K,G5. Nasal sounds: N-M-Ng Effect of complete denture on speech

(prosthetic factors affecting speech): A. Denture base:1- Denture base thickness:Thin well adapted denture base (1mm thickness) not greatly affect the speech  Increasing the thickness of the denture base leading to cramping of denture space, decrease air volume and obstruction air channels  Thickening the denture base in the anterior palatal → lisping (S pronounced Ch), and T pronounced D Thickening the denture base in posterior palatal border → defect in vowels (e,i) and consonants (k,g), so the border should be smooth tapered and merge with the soft palate (not form a square edge) Thickening the denture base at lower lingual flange → cramping of tongue space → lisping Decreasing the thickness of the denture base → whistling, D pronounced T2- Extension of the denture base Proper extension of the denture flanges aid retention and stability of denture

which help in proper articulation of sounds as with poor retention, the tongue try to reseat the denture against the palate during the speech. Avoid overextension of the flanges to decrease interference with muscle movement during speech → indistinct speech especially if the lip affected3- Polished surface Reproduction of incisive papilla and rugea area (by wax carving –tin foil) on the polished surface of the anterior palate aid in correct production of anterior palatal sounds. B. Denture relations:1- Occlusal plane Too high occlusal plane: tongue spread on the lower teeth→ lisping (S pronounced Ch), and F pronounced V Too low occlusal plane: difficulty in correct positioning of the lower lip and tongue contact occlusal surface during the speech → V pronounced F2- Vertical dimension Increased vertical dimension: denture teeth make contact during speech→ clicking,

defect in Ch-C-J sounds, whistling, Th pronounced T due to failure of the tongue to be placed between anterior teeth  Decreased vertical dimension: leading to lisping (S pronounced Ch) M sound: used as an aid to obtain correct vertical dimension. When the patient say M, if the lips are straightened and unable to make contact, the record blocks are occluded prematurely and the VD is high  S sound: also used as an aid to obtain correct vertical dimension. When the patient say S (sixty-six), the upper and lower teeth should be separated 2mm from each other (closest speaking space method)3- Teeth arrangements: 1- Width of the dental arch:  Too narrow dental arches→ the tongue cramped and the size of air channel decreased → faulty articulation of consonants (T-D-N-K-C), therefore, the teeth should be placed in the position previously occupied by natural teeth 2- Antro-posterior position of

the anterior teeth Upper anterior teeth Too far palatally:- Upper incisors difficult to contact the upper lip → affect labiodentals sounds (F-V)- Tongue make contact with the teeth prematurely → affect lingupalatal sounds→ lisping (S pronounced Ch), T pronounced D Too far labially: whistling and D pronounced T Lower anterior teeth: Too far lingually: Th pronounced T and the tongue rested in the floor of the mouth behind lower anterior teeth in pronunciation of vowels Too far labially: affect pronunciation of vowels.3- The relationship of upper and lower anterior teeth Abnormal protrusive or retrusive Jaw relations (class II, class III angle classification) associated with increase or decrease the overjet leading to difficulty in pronunciation of S sound (increase overjet→ whistling)

Regarding option a) for the s or sh sound, this is an obnoxious question,,the tongue becomes flat and there is no 'tip of tongue' as such,,so it is a bit diff. To assess what part actually touches. If still the tongue touches the anterior palate, the necessary sound will not at all be produced..

A) hemophiliaB) during 's' or 'sh' sound, tip of tongue touches max canines,,that's the best poss answer,,,Ref-we can all see that in the mirror and say !!! ajithaC) to provide enough space.
