Brief summary

The dehiscence distal to the second molar after lower third molar extraction is very common because the access flap for surgical extraction cannot be repositioned on a portion of healthy bone to guarantee suture support. The healing process is therefore delayed and the possible accumulation of food and debris is often responsible for bad smell and pain with the consequent occurrence of an overlapping infection. The main aim of the study is to evaluate whether healing is significantly different using two different flaps for surgical access. Clinical assessment and a quality of life questionnaire are used for the evaluation.

Interventions

the extraction is performed with one of the two type of flap based non randomization.

Design outcomes

Primary

MeasureTime frameDescription
wound healing day 22 days after surgerya clinical chart is complete to evaluate if in the group of lower third molar extracted with a bayonet flap the proportion of healing without dehiscence (good healing index) is significant greater than in the group of third molar extracted with an envelope flap.
wound healing day 77 days after surgery, at suture removala clinical chart is complete to evaluate if in the group of lower third molar extracted with a bayonet flap the proportion of healing without dehiscence (good healing index) is significant greater than in the group of third molar extracted with an envelope flap.
wound healing day 1414 days after surgerya clinical chart is complete to evaluate if in the group of lower third molar extracted with a bayonet flap the proportion of healing without dehiscence (good healing index) is significant greater than in the group of third molar extracted with an envelope flap.

Secondary

MeasureTime frameDescription
quality of life day 1414 days after surgerythe patient complete a HRQOL questionnaire (modify from Shugars DA et al 1996) to evaluate if differences exist in the patient's quality of post-operative life in relation with two types of flap; we use visual analog scales (VAS) for post-operative pain and five-points Likert-Type for swelling, chewing, speaking, sleeping, sport and daily routine activity; higher scores mean a worse outcome.

Full Mouth Plaque Scorepre-operativeFull-mouth plaque score was recorded dichotomously (presence/absence of plaque) on six sites per tooth and was then calculated as the percentage of total tooth surfaces that revealed the presence of plaque; higher percentage mean higher presence of plaque
Partial Plaque Scorepre-operativePartial plaque score was recorded dichotomously (presence/absence of plaque) on six sites per tooth in the arch of extraction and was then calculated as the percentage of total tooth surfaces that revealed the presence of plaque; an higher percentage means higher presence of plaque
