what is the failure of normal fusion of embryonic process during developmen

cleft lip and palate


when does the formation of the lip occur

between the 4th or 7th week in utero


when is the cleft lip apparent

end of second month in utero (8 month)


when does the development of the palate happen

takes place during the 8th to 12th week


when is the cleft palate evident

by the end of the 3rd month 12thweek


what is a class one cleft palate

cleft of the tip of the uvula


what is a class two cleft palate

cleft of the uvula


what is a class three cleft palate

cleft of the soft palate


what is a class four cleft palate

cleft of the soft and hard palate


what is a class five cleft palate

cleft of the soft and hard palate that continues through the alveolar ridge on one side, associated with cleft lip of the same side


what is a class six cleft palate

cleft of the soft and hard palates that continues through the alveolar ridge on both sides, free premaxilla, bilateral cleft lip


what is a class seven cleft palate

submucous clef in which the muscle union is imperfect across the soft palate, short palate, uvula is often bifid, groove situated at midline, closure of pharynx isnt complete


what are risk factors for a cleft lip or palate

multifactoral, genetic and environmental


what are environmental factors for a cleft lip or palate

-tobacco, alcohol consumption, teratogenic agents, inadequate diet


what occurs more frequently in patients with clefts than in the general population

disturbances in normal tooth development


what is there a higher incidence of in cleft lip and palate

missing and supernumerary teeth, missing max laterals correspond to side of mouth with cleft


do people with cleft lip or palate require ortho care

yes, may be required after each stage of surgical tx


what is there a lack of in coordinated movements in patients with a cleft lip or palate which may cause the pt to have compensatory habits

-coordinated movement of lip, tongue, cheeks, floor of mouth, throat,


what is dental biofilm accumulation influenced by in patients with cleft palate or lip

irregular positioned teeth, inability to keep lips closed, mouth breathing, difficulties in personal oral care


what is common in periodontal tissues at the cleft site in adolescents

loss of bone and clinical attachment


where is periodontal tissue loss greatest at

cleft sites


what puts patients with a cleft lip or palate at a higher risk for caries

-malpositioned teeth, mastication problems, diet selection, dental biofilm


what contributes to ECC in patients with cleft lip or palate

-feeding difficulties of infants


in more than 300 disorders, cleft lip, palate or both represent one feature of what

a syndrome


what do factial deformities include in cleft lip or palate

-depression of nostril on side with cleft
-deficiency of upper lip
-overprominent lower lip


what infections are common in cleft lip or palate

upper respiratory infections, middle ear infections


craniofacial anomilies of the nose and throat predispose the child with a cleft palate to

airway obstruction and breathing problems


do patients with a cleft lip or palate have difficulty making certain sounds



what contributes to speech problems

-anatomic structure, airway and breathing problems and hearing difficulties


hearing loss is ______ than in individuals with a cleft palate



when is surgical union of the cleft lip made

at 2 to 3 months of age, 10 weeks of age, weighs 10 lbs, serum hemoglobin of 10 mg/ml


what are purposes of early tx of a cleft lip

-aids in feeding
encourages dev of premaxilla
partial closure of a cleft


when is primary surgery to closure of the palate done

by age 18 months or earlier when possible


what are the goals for tx of closure of cleft palate

achieve normal function, (speech)
relive problems of airway and breathing
-dental esthetics and functional occlusion


what may secondary surgery of the cleft palate include

-lips, nose, palate and jaw


what are the objectives of secondary surgical procedures of a cleft palate

improve function for coherent communication, improve appearance


what are specific procedures of secondary surgical procedures

-rhinoplasty, nasal septal surgery
-velopharyngeal flap
-closure of palatal fistuale
-tonsillectomy or adenoidectomy


When is an alveolar graft placed in palatal surgery

before eruption of maxillary teeth at the cleft site


what does an alveolar graft do

creates a normal archetecture, support is provided for teeth


what are teh 2 types of prosthesis in clefts

obturator- removable prosethesis closure of palatal opening
speech aid prosthesis- removable, completes palatopharyngeal valving


what are the purposes and functions of a prosthesis for a cleft

-closure of palate
replacement of teeth
fill out upper lip
masicatory function
restoration of vertical dimension
postorthodontic retainer


when may orthodontic treatment be initiatied in a cleft

as early as 3 years old


when is speech therapy training started and what is the emphasis

-with very young children
-emphasis after the surgical or prosthodontic tx


what is a major problem in restorative dentistry in cleft patients

dental caries


what is the frequency of maintenence of cleft patients

3 or 4 months, difficult to keep teeth clean


what are some of the objectives of appointment planning

-review dental biofilm control
-provide encouragement
-to remove all calc and smooth surfaces
-supervise a caries prevention program


why may patients have apprehension at appointments

-clinic tired
-low self esteerm, difficulties in social interactoins


what should we know about speech in patients with clefts

-speech may be almost indiscernible, referral for speech assessment


what would we know about hearing in patients with cleft

approach is similar to speech difficulties


what kind of instructions should we provide in a patient with clefts

-personal daily care- select tb and method
-fluoride- fl2 dentifrice and diet supplements
-rinsing instruction for older pts (over 6)
-prostesis or speech aid- halitosis may be problem

-prep mentally


what should patient be made aware of post surgically of personal oral care of cleft lip or palate

-rinse mouth carefully
-water irrigation
-great care to surgery site, careful


What may be done in preparation for dental surgery as far as dental hygiene care
