maintence Flashcards
what are the general objectives?
survival of functional dentintion with satisfactor esthetics for ptns
What are the objectives specific for perio?
prevent reinfection
maintain attachment levels
what are the goals of periodontal therapy?
- maintain stability of attachment levels: improve/gain attachment when feasible
- keep inflam severity as low as possible
- maintain a functional and esthetically pleasing dentition for ptn
what are the goals of maintenance?
- to minimize recurrence and progression of Pd in ptns who have previously been treated
- to reduce incidence of tooth loss by monitoring the dentition and any prosthetic replacement of natural teeth
- to increase the probability of locating and treating, in timely manner, other disease or conditions found within oral cavity
in a study with 77 ptns with advanced PD, the re-exam done in ___ months? This lead to two groups of patients? Then Reeval after ___ years?
2; 52 ptns rigorous maintenance and 25 ptns general practitioner; 6 years
In study of attachment level changes, % of surfaces showing changes from 2 month exam: AL gain in maintenance vs control? AL stable? Attachment loss <= 1mm? 2-5 mm?
17, 01;
72,10;
10, 34;
01, 55
What are the results of proper maintenance? (5)
- preservation of alverolar bone support
- stability of attachment levels
- inflam levels kept low as possible
- improved self-performed plaque control and motivation
- preservation of oral health
what are the purposes/classifications of maintenance?
preventive, trial, and compromise
What is preventive maintenance? Where does it fit in the flow chart?
healthy patient;
- initial exam
- diagnosis
- nonsurgical therapy/cause-related therapy
- reevaluation
- then retreatment surgical/nonsurgical & maintenance
- retreatment surg/non also goes to maintenance
What is trial maintenance and where does it fit in flow chart?
questionable prognosis, assess need for further treatment;
- non-surgical tx
- reeval
- maintenance
- goes to both surgical tx and restorative tx (these can go back to maintenance)
- surgical also goes to restorative
What is compromise maintenance and where does it fit in the flow chart?
special situations in which the results of therapy are less than-ideal;
- periodontal exam
- nonsurgical perio therapy
- to both maintenance and 6 wk post-nonsurgical therapy eval
- both maintenance and additional nonsurgical perio therapy or proceed to perio surgical therapy
- both maintenance and 6 wk post therapy eval
- again to maintenance
what factors included in initial diagnosis? (3)
anatomic consequences of disease progression, inflam changes, presence of local eto factors
what is included in anatomic consequences of disease progression? (3)
attachment loss, pocketing, mobility
what is included in inflam changes? (2)
gingival margin
bottom of pocket/subgingival
what factors involved in maintenance diagnosis?
diagnosis and assessment levels of risk factor for recurrence
what is involved in maintence diagnosis?
comparative to the previous appointment
also consider stability in comparison to status after active therapy (reeval)
what assessment levels of risk factor for recurrence?
- ptn/individual- interval b/t appointments
- tooth- time allocation during the appointment
- site- type of procedure/intervention
what is the rationale for maintenance?
dynamic health-disease process
persisstance of eto factors
motivation
what is involved in motivation in rationale for maintenace?
transmission of periodontopathogens
interference on biofilm (OH deficient in some areas)
what are the effects of a single episode of mechanical disruption of subgingival biofilm?
- decrease on total # of m. os.:
up to 90%/site, 42 days for recolonization by periodontopathogens - changes on microbial ecology:
interference on biofilm, increases on initial colonizers (commensal, non-pathogenic bacteria)
effect of subgingival instrumentation on microbial biofilm?
right after instrumentation, very little patho and nonpathogenic bacteria;
later get recolonization w/ greater number of nonpathogenic bacteria and very little pathogenic
