1
The aim of focal infections in dentistry
Dr. Mensch Károly 2018
2
Questions 1 . Contraindication of dental treatment related to general health condition 2. What are the problems associated with chronic myeloproliferative diseases from in dentistry? 3. List some states with immundeficiency 4. What kind of INR should not be changed the anticoagulkant therapy? 5. When not to recommand /prescribe a conventional non-steroid medication?
3
Answers Acut infestive diseases, AMI, hospitalisation (psychiatric diseases, anaphylaxia in anamnesis…) Haemorrhagia, immundeficiency, ulcus Transplantation, chemoth, HIV, biological th Under 3,5 Gastroduodenal ulcer, gastrointestinal bleeding in anamnesis
4
Importance Organism affects the oral cavity
BUT the oral cavity affects the organism Oral cavity: the most infected organ Role of dentists: Identificate the lesions of oral cavity, prevent and treat them
7
Definition- Focal infection
An acute or chronic infection in which bacteria are localized in some region of the body, as the tonsils or the periodontal tissue, from which they or their metabolites or toxines may spread to some other organ or structure of the body causing secunder diseases
8
Characteristics of focal infections
Chronically infected areas Asymptomatic or few symptomes Encumbering the organisation via various mechanism Open or closed focals
9
Dental Focuses Open focuses
Caries lesions: microorganism from the caries surface can pass into the blood-stream via micro-traumas Gingivitis, periodontitis: OPEN focuses Alveolitis: bacteria can pass into the blood-stream from destructed and infected coagulum
10
Periodontitis- as focus
The cause is the dental plaque: >99% of microorganisms Deep pockets contact with the periodontal connective tissue and capillars In the case of it, the bacteria can spread during chewing and tooth-brushing IF, we hypotize 5mm deep pockets around every teeth = 100 squarecentimeter wound
11
Dental Focuses Closed focuses: Necrosis of pulp Periapical lesions
Incomplete root-canal fillings (theoretically every root canal treated teeth are focus, we have to reflect the case.. ) Radix relicta Residual cyst Impacted teeth with follicular cyst
12
Mechanisms of focal infections
Metastatic infection from oral cavity via transient bacteremia Metastatic toxical effect: via toxins of oral microorganisms Metastatic inflammation: cascade of immune-mechanisms Via inflammatory cytokines: microorganisms product cytokines: damage in an other area of body
13
Bacteriemia Dental treatmens with bacteriemia!
Supra and subgingival scaling, curettage Extraction, oral-surgical treatments Endodontic treatments Intraligamental anesthesia BUT during tooth-brushing also (poor oral hygiene) 30 sec after treatment, but latest in 10 Min

15
Focal infections If the cause of some disease of an organ is a chronical inflammation of an other organ (far from the damaged area)= focal infection Most common chronical inflammations causing focal infection: Dental focus- MOST COMMON Common: upper respiratory-tract: Tonsillitis follicularis 10%: gall bladder, appendix, prostata, female genital tract
16
Secunder focal infections
Cardiovascular diseases: Atherosclerosis, AMI, STROKE, IE Respiratory diseases Diabetes Mellitus Premature birth Rheumatoid arthritis Nephritis Inflammation of the Iris Allopecia areata Eczema
17
Cardiovascular focal-infections
Atherosclerosis: Chr. Periodontitis: Porphyromonas ging, Tenerella forsythia isolates from atheroma Ischemic heart diseases, acute myocardial infarct Stroke Infective endocarditis: Streptococcus, Actinobacillus, Fusobacterium, Eikenella Bacteremia case of poor oral hygiene, during chewing or bleeding dental treatment ANAMNESIS, ORAL HYGIENE, PROPHYLAXIS
18
By Sarah BC Williams
19
Infective Endocarditis prophylaxis
Injure of endotheldeposit of thrombocyts bacteriemia: bacteria into this deposits: endocardial vegetations High mortality NOT common: souls- 30 cases /year
20
Need of IE prophylaxis Moderate Risk patients: High Risk Patients:
heart valve diseases hypertrophic cardiomyopathy mitrale valve prolapse High Risk Patients: artificial heart valve pulmonal shunt anamnesis: endocarditis cyanotic heart diseases
21
IE Prophylax NOT needed:
Atrial heart diseases Operated ventriculare diseases Operated coronary diseases Pacemaker Making prostese, Impression, Filling, X-ray
22
IE prophylaxis Moderate Risk patients: High Risk Patients:
2g Penicillin, 1h before the treatment, Penicillin allergy: 600 mg Clyndamycin per os, or 1g vancomycin IV High Risk Patients: + 1,5 mg gentamycin before the treatment, 6 hours after treatmen again If possible in one seat! RESISTENCE
23
Respiratory focal-deseases
Aspiration Pneumonia: Periodontopathogens: Actinobacillus, Eikenella, Fusobacterium: NOSOCOMIAL PNEUMONIA. Intubation, artifitial respiration: CHX prophylax COPD: Case of Periodontitis: more common
24
Rheumatoid Arthritis Autoimmun Desease
Porphyromonas ging. was isolated from synovia: CCP (cyclic citrullinated peptide) catalysis: Autoimmun process
25
Diabetes Mellitus, as Focal Disease
There-and-back effect! Mainly: cause of NIDDM Bekteriemia: Increas the inzulinresistance of tissues Untreated periodontitis: more severe Diabetes
26
Premature birth- dental focus
According to literature: >4mm Pocket + 50% BOP significant higher risk to premature birth Mother with vs without periodontitis? weight of newborns: 2834g vs 3180g Group of mothers has premature birth: more komplex microflora in the oral cavity Porphyromonas gingivalis, Fusobacterium nucleatum, Lactobacillus: leading role in premature-birth causing by periodontitis. Increased Prostaglandin level, (contraction of myometrium)
27
Alopecia areata Follicular hair loss Unclear pathomechanism
Dental focal: sure, IF the hair-loss will end after remove the focal-tooth. Lokalization: same side, Maxilla: cranial direction; Mandibula: caudal direction
29
Psoriasis Papulosqamous skin-disease
White or red hyperkeratotic maculas overall the body Caused by extrinsic or intrinsic triggers Dental focal can be a trigger also Unclear!
30
Uveitis Inflammatory desease of the eyes (Iris, Uvea, Corpus ciliare)
Pain, twinge of the eye, red eyes, unclear view Focal infection??? BUT Have to think!
31
Dental focal- consultation
Every day in the praxis Responsibility! Clinical and radiological examination Expertise
32
Where are the patiens coming from?
Dermatologist- alopecia areata, ekzema, psoriasis Gynecologist, Urologist Rheumatologist CARDIOLOGIST Prior to TRANSPLANTATION Prior to Bispfosphonate treatment ??
33
Steps of dental focal examination
General anamnesis- e.g. IE Extraoral examination- Lymphnodes (acute, mobile, painful!!) Examination of teeth OPG, intraoral X-ray Expertise We have to give coverage for the Patient
34
Clinical examination of teeth
BOP, Pocket depth !!! Mobile teeth- Periodontis Big caries leasions, fillings, crowns: Sensibility examination Vertical and horizontal percussion Palpation of apical region
35
Radiological examination
OPG: not enough!- only show us which teeth we have to make an IO X-rey from- RCT, Radix, periapical tissue. BUT able to examine the Periodontal status. IO X-ray needed, if: Sensibility neg. Percussion: sensitive teeth Teeth with sensitive periapical region Big caries, fillings or teeth with crowns
37
Evaluation of clinical and radiological examination
We have to reflect the secunder focal disease. E.g: prior to a heart transplantation. Radical elimination of every potentially focals (every RCT teeth) but alopecia areata: only the really focals have to be eliminated RCT teeth: WITH periapical lesions: really focals Without of periapical lesions: potentially focals
38
Focal-finding Responsibility
We write our findings only in the case of wroten ask We have to write: According to our clinical and radiological examination, XY : Without of any dental focals Closed focal: e.g. periodontitis apicalis chronica of upper first molar left. Open focal: caries, gingivitis, periodontitis Potentially focals: RCT teeth without of periapical lesion
39
Coverage for Patients Why are we looking for a focal?
We write only the Dg, the specialist has to indicate the treatment (Cardiologist, Dermatologist..)! Prior to Bisphosphonate treatment: radical elimination of focals would be needed Where can be treated?
