Infection Control Audit
Background• Infection control refers to policies and procedures used to minimize the risk of spreading infections in hospitals and health care facilities.
ЖGoals of Infection Control:ЖProtect the patientЖProtect the health care worker, visitors, and others in the health care environment, and
ЖAccomplish the previous goals in a timely, efficient, and cost-effective manner, whenever possible.
Objectives•To identify if infection Control Methods
are adhered to

Recommendations
• Implementation of a standardised hospital control policy.• Training of all personal who are subject to occupational
exposure: dental health care professionals, dental nurses, students.
• Provision of antimicrobial handwash and lotions in all departments.
• Proper clearing of sharp containers.• Clear waste disposal policy; differentiation between clinical and
non-clinical waste
• Schedule for regular cleaning• Staff must use heavy-duty utility (puncture and chemical-
resistant) gloves, and wear eye protection/face shield and a mask
• Used dental instruments should be pre-cleaned by wiping at the chairside.
• A long-handled instrument brush should be supplied• Immunisation and maintain immunisation records• Exposure incident protocol• Re-audit in July
RadiographAudit
Background▪ Why audit radiographs?
There is a need to minimise or eliminate:▪ Radiographic examinations where the results are
unlikely to affect patient management and/or prognosis▪ Radiographic examination which are repeated
unnecessarily▪ Duplication of radiographic examinations which have
been done already▪ Inappropriate radiographic examinations▪ Avoidable lapses in quality assurance which impact on
patient dose and care
Objectives
▪ To identify the quality ratings of periapical radiographs taken at Academy Dental Hospital during the period of September - December 2015
Criteria/Standards
The NRPB suggests the following standards for subjective quality rating of radiographs:
▪ No less than 70% of dental images should have a rating of Excellent – No errors of patient preparation, exposure, positioning, processing or film handling.
▪ No more than 20% should have a rating of diagnostically acceptable – Some errors present, but do not detract from the diagnostic utility of the radiograph.
▪ No more than 10% should have a rating of Unacceptable - Errors which render the radiograph diagnostically unacceptable.

Recommendations
• Appropriate training of the hospital’s staff• The use of collimation and thyroid collars• Receptor holders align the receptor precisely with the
collimated beam (parallel technqiue)• Personal dosimeters should be used by workers • Introduction of other intraoral radiographs: bitewing
radiographs• Radiographs should be documented correctly• Re-audit in July
Endodontic Complications
BackgroundThe aetiology and diagnosis of dental pain and diseases
are integral parts of endodontic practice. Endodontic procedures should be practised with the required level of
skill and on the basis of sound scientific knowledge.
According to the European Society of Endodontology, a competency-based approach to training implies that the quality and consistency of student performance are more important than simply the quantity of clinical exposure.
For root canal treatment, students should be competent to undertake the treatment of uncomplicated molar
teeth, and all students should gain adequate experience in the treatment of anterior, premolar and molar teeth in
both the pre-clinical and clinical environment.
Objectives• To identify the percentage of complications
encountered during endodontic treatment performed by 5th year dental students
• Ascertain that correct guidelines are followed when providing root canal treatment
Criteria/Standards• Quality guidelines for endodontic treatment: consensus report of the European Society of
Endodontology 2006
• European Society of Endodontology-Undergraduate Curriculum Guidelines for Endodontology 2013

Access Cavity
₰ Extension: Regarding the extension of access cavity walls, 31% were found to be overextended; the majority of overextension in anterior teeth was found in canines (40%), while in posterior teeth lower molars were more commonly overextended (35%)
₰ Deroofing: 88% of teeth were sufficiently de-roofed. Of those 12% which were not deroofed, the most commonly involved teeth were the molars (15 out of 64 teeth).

Discussion and Recommendations
Case selectionFor root canal treatment, students should be competent to undertake the treatment of uncomplicated molar teeth, and all students should gain adequate experience in the treatment of anterior, premolar and molar teeth in both the pre-clinical and clinical environment. (European Society of Endodontology-Undergraduate Curriculum Guidelines for Endodontology 2013)
When selecting a case, the students should anticipate all the difficulties that may be encountered, and prepare for these ahead of time. The knowledge of one’s own clinical skills and limitations, plays an important role in case selection.
It is clear from our study, that many difficulties have been encountered, many complications have arisen throughout all stages of root canal treatment, some of which have been overcome.
Detailed assessment of cases prior to treatment, and implementation of the AAE Endodontic Case Difficulty Assessment Guidelines may warrant adequate provision of dental treatment, through the anticipation of expected difficulties and preparation through provision of adequate instrumentation, and the use of various techniques.
Access Cavity• Guidelines that should be followed when preparing an access cavity are as
follows (Pathways of the Pulp, 10th Edition, Stephen Cohen):• Visualization of the Likely Internal Anatomy• Preparation of the Access Cavity Through the Lingual and Occlusal Surfaces• Removal of All Defective Restorations and Caries Before Entry Into the Pulp
Chamber• Removal of Unsupported Tooth Structure• Creation of Access Cavity Walls That Do Not Restrict Straight- or Direct-line Passage
of Instruments to the Apical Foramen or Initial Canal Curvature• Delay of Dental Dam Placement Until Difficult Canals Have Been Located and
Confirmed• Location, Flaring, and Exploration of All Root Canal Orifices
• In our study, 31% of access cavities were overextended, while 3% were underextended. The remaining 66% were good. This could be improved through education by highlighting the precise location of the canals, as well as emphasizing removal of caries and infected dentine using excavators, and low speed handpieces instead of using high speed handpieces.
• 21 out of 175 teeth didn’t have satisfactory deroofing. The result of this is impeded access of instruments to the coronal 1/3 of the root. (Oxford Handbook of Clinical Dentistry, Laura Mitchell, 6th Edition)
• 52% had touched the floor of the pulp chamber with the handpiece. It should be emphasized that students should not search for the canals using the handpiece, and adequate endodontic explorers should be provided, to aid in location of the canals.
• Straight line access was least satisfactory in lower molars (50%). Straight line access could be carefully created in these cases using Gates-Glidden burs and NiTi orifice shapers. Students should be made aware of the use of various techniques available to help with such difficulties.
Recommendations• Introduction of various instruments such as pluggers, and replacement of
old damaged instruments such as excavators, and explorers.• Division of the students between teaching assistants to provide a more
concentrated learning experience and keep better track of their progress.• Presenting an ‘Introduction to Endodontics’ course to third year dental
students, helping them prepare for preclinical endodontics.• Posters identifying recent diagnostic terms, criteria of obturation,
different techniques to approach difficult cases, and handouts to highlight the importance of case selection.
• Students should practice using rotary endodontic instruments on extracted teeth, prior to working on patients.
