To gather a group of clinicians with the relevant expertise or interest to discuss on the issue of concern
Through structured critical discussion on the relevant evidence during the process, to produce clinically useful comments, recommendations, guidelines, or consensus statements on the concerned issue

lIt was found that many studies on chemical plaque control involve certain amount of bias and heterogeneity.
lIn a comprehensive review “Efﬁcacy of adjunctive anti-plaque chemical agents in managing gingivitis: a systematic review and meta-analysis” by Serrano et al.in 2015, it stated that: “Regarding the independency of the study, in terms of funding and authors, most of the studies were economically supported by private companies with commercial interests in the results, which were clearly stated in the paper (n = 43) or was evident due to the presence of employees of the company in the list of authors (n = 31). Independent researchers (e.g. university staff) were authors in 70 papers, but in 38 of them, they worked together with employees of the funding company (total, n = 53) and/or with staff from a private research company (total, n = 24). Considering as low risk of bias those studies with independent authors and funding, four had low, eight unclear and 75 high risk.”
lHowever, with all the existing available evidence, it was found that chemical plaque control provides statistically signiﬁcant additional benefit over the control groups
lThe clinical benefit varied with different agents and with different indices used in the studies.
The additional effects were statistically significant in terms of Loe & Silness gingival index (46 comparisons, WMD -0.217), modified gingival index (n = 23, -0.415), gingivitis severity index (n = 26, -14.939%) or bleeding index (n = 23, -7.626%), with significant heterogeneity. For plaque, additional effects were found for Turesky (66 studies, WMD -0.475), Silness & Loe (n = 26, -0.109), and plaque severity (n = 12, -23.4%) indices, with significant heterogeneity (Serrano et al. 2015).
lWhether this benefit offer any clinical value is subjected to interpretation.
lThe studies didn’t address the cost-effectiveness issue
lNo specific recommendation for target group of patient who will benefit most from chemical plaque control
lIn many studies, participants in the control group were allowed to brush according to their normal regimen without proper oral hygiene instruction.
lAs early as 1965, Lo¨e et al. Showed, in the well-known “Experimental Gingivitis” study, that proper mechanical tooth brushing is effective in treating gingivitis.
lLang et al.(1973) demonstrated that students who thoroughly removed plaque at least every second day, did not develop clinical signs of gingival inflammation over a 6-week period. This included the use of inter-proximal aids (dental floss and toothpicks) as well as the toothbrush.
lIn the well-motivated and properly instructed individuals who are willing to invest the necessary time and effort, mechanical measures using traditional toothbrushes and adjunctive manual (inter-dental) devices are effective in controlling plaque. Although maintaining a dentition close to plaque free is not easy.
Comments and recommendations
1.One should not rely on chemical plaque control to solve gingivitis problem. On the other hand, good mechanical plaque control can prevent and successfully treat gingivitis.
2.Mouth rinse should not be recommended as the first line of management strategy for gingivitis.
3.We recommend improving patients’ oral hygiene by mechanical tooth bushing and interdental cleaning.
4.Toothpaste with antiplaque agent may be used as it does not involve extra procedure.
5.Routine use of mouth rinse for everyone is not recommended.
6.Mouth rinse may be used in certain clinical situations: (Whenever patient is unable to perform proper mechanical plaque control).
a.Temporary use after oral surgery.
b.Inability to clean at certain areas.
c.Patient with reduced manual dexterity.
d.When patients, due to various reasons, cannot achieve sufficient oral cleanliness after repeated exhaustive effort of oral hygiene instruction.
When prescribing mouth rinse, clinician should also take into account of the possible side effects and cost-effectiveness of its use.
In the Oral Health Survey 2011, 15.4% Hong Kong people believe mouth rinse can prevent gum disease but only 47.9% think that tooth brushing can prevent gum disease.
One should be careful when people over enthusiastically promote the effect of chemical plaque control, there is a risk that the public may misinterpret chemical plaque control agent as a powerful and essential agent that they can rely on, hence compromise the desire to improve their own tooth brushing.

Lecture 1 + AGM
Lecture 2 and Periodontal Experts Panel Discussion
Common head and neck pain that you would encounter in a dental clinic
Date: 11 November 2016 (Friday) Time: 7:30-9:30 Speaker: Dr Sunny Lee (Specialist in Pain Medicine) Venue: 7/F Lounge, PPDH
Course fee: $500 (Free for members)
Light refreshment provided before and after the seminar
Dr Lee graduated from the Chinese University of Hong Kong. After finished his training in Anaesthesiology and Pain Medicine in Hong Kong, he went to Australia to pursuit further training in pain medicine. After practicing in Australia for some time, he went back to Hong Kong and became the first registered pain medicine specialist here. Currently, he runs his private practices in both Hong Kong and Australia. He is the pioneer in many areas in the field. For example, he is the only private practitioner providing services for spinal cord stimulation at present.
Pain is a commonly encountered problem in clinical practice. It is considered as the fifth vital sign in modern medicine. Researches show chronic pain affects about 20% of population. In the talk, the speaker would share with the audiences different aspects of pain medicine. He would explore some basic science of pain, principles of pain treatment, types and nature of analgesics and some commonly encountered chronic pain problems that may encountered by dentists.
