Nonsurgical Perio Therapy and Maintenance


Course Objective

Competences covered according to the General Educational Framework
Dentistry 2008: I a-j (5), II (5)
The student
• understands the effects of oral hygiene methods, scaling and root
planning (hand and mechanical methods) related to the various forms of
periodontal diseases and various locations in the dentition, to be able
to critically apply this in practice.
• understands the morphology of single rooted and multi-rooted teeth and
have adequate knowledge on the specific local risk factors for proper
therapeutic choices.
• understand the pharmacological characteristics of various antibiotics
and have deep knowledge on the clinical effects of various antibiotics
for the purpose of critical analysis when and how to apply antibiotics.
• understands the pharmacological characteristics of various antiseptics
and have deep knowledge on the clinical effects of various antiseptics
for the purpose of critical analysis when and how to apply antiseptics.
• understands the principles of normal and pathological dental occlusion
and articulation and be familiar with the literature relating to the
(un)necessity of various treatment modalities for occlusion/articulation
problems in relation to periodontal pathology and periodontal therapy.
• has thorough knowledge on the concepts of supportive periodontal
therapy (maintenance) to critically analyse past, current and future
developments in this subject.

Course Content

This module focuses on all aspects of non-surgical periodontal therapy
for the patients with various forms of periodontitis. Ever since the
early 1960’s it is well accepted that the first steps of any periodontal
therapy are improvement of the patient’s oral hygiene. Since the 1970’s
and 1980’s a deep understanding has arisen on the effects of scaling and
root planing of periodontally affected teeth in conjunction with good
oral hygiene.
The course therefore focuses on the clinical and microbiological effects
of this most applied therapy in periodontology. It is imperative that
the students have complete knowledge on the tooth root morphology, as
this affects the success of the applied non-surgical therapy. There is
in some situations a need to prescribe systemic antibiotics; the
indications are taught in this course. Also the prescription, usage and
compliance of antibiotics by the patient will be dealt with. In
addition, professional application of local antibiotics will be studied.
Another part of the non-surgical periodontal therapy is the possible
need for occlusal adjustment of the teeth. The needs and the
contra-indications have been studied and the course will deal with this
subject. Patients with periodontitis need regular maintenance and
after-care; the intervals, the risk factors, prognosis of a case and the
clinical procedures around this issue (i.e. supportive care) are also
part of this course.

Teaching Methods

Literature, research and self-study; assignments; working groups,
intervision and supervision

Method of Assessment

Learning assessment
• Overall assessment of assignments during the seminars (grade: good /
pass / fail)
• Written exam: open ended questions (grade: 1-10)

A prerequisite for grade registration (grade 0-10) is successful
completion of the seminar assignment(s). In case of a fail for the
seminar assignment(s), and a pass for the final exam, a 5.0 will be
registered and students will need to redo the relevant seminar


• Readers with selected papers (compulsory)
• Capita selecta from Lindhe, J., Karring, T. & Lang, N. P. (eds).
