Tooth impaction is one of the most common pathologies in our everyday practice. Over the recent years there has been a debate over the advisability of removing symptom-free wisdom teeth or leaving them in place. One of the main reasons for removal of a symptom-free wisdom tooth is high incidence of later complications, low incidence of their eruption, especially after the age of 25, and 2 times greater risk of complications after the age of 24. Objectives. The aim of our investigation was to systematize a scheme of objective preoperative clinical and roentgenological assessment of mandibular impacted symptom-free wisdom teeth to create a rationale for their prophylactic removal. Material and Methods. 84 clinical cases of patients with impaction of asymptomatic and without any considerable pathological changes mandibular third molars, who have been treated in the Department of Surgical Dentistry and Maxillofacial Surgery of Lviv Danylo Halytsky National Medical University during Results. For the justified removal of a symptom-free mandibular impacted third molar, we processed known clinical, roentgenological parameters, which characterize asymptomatic and without any considerable pathologic changes mandibular impacted third molars and do not belong to the list of indications and contraindications to atypical removal. There were no considerable intra- or postoperative complications in the first subgroup (41 cases of patients years old); minor complications in the second subgroup (10 cases of year old patients). In the case of 68 year-old patient surgery, all complications were related to considerable bone atrophy of the operated area. 5 of 7 clinical cases from control group #1 needed surgical intervention because of the appearance of indications during the next 5 years of follow-up. Mandible third molars from control group #2 during the last five years still have had no pathological changes that may warrant their removal. Conclusions. Considering the abovementioned, all the chosen criteria facilitate the formation of indications for a proper treatment tactic regarding asymptomatic impacted lower third molars without any considerable pathological changes. The low-to-no percentage of intra- and postoperative complications does not give any reason to leave a wisdom tooth with minor clinical manifestations or an asymptomatic wisdom tooth with bad prognosis in place, since early surgical procedures generate less number of complications, having shorter operative time and postoperative period (Dent. Med. Probl. 2014, 51, 1, 35 42). Key words: asymptomatic third molar, impaction, atypical removal. Streszczenie Wprowadzenie. Zatrzymanie zębów jest jedną z częstszych patologii w codziennej praktyce. W ostatnich latach toczy się debata nad kwestią konieczności usuwania bezobjawowych zębów mądrości lub ich pozostawienia. Jednym z głównych powodów usuwania bezobjawowych zatrzymanych zębów mądrości jest duże prawdopodobieństwo późniejszych powikłań, małe prawdopodobieństwo ich wyrżnięcia się, zwłaszcza po 25 roku życia i dwukrotnie większe ryzyko powikłań po 24 latach.

Pokazanie całego zakresu objawów klinicznych i radiologicznych zatrzymanych trzecich zębów trzonowych w żuchwie w celu uzasadnienia konieczności ich profilaktycznego usuwania. Materiał i metody. Materiał stanowiło 84 wyselekcjonowanych pacjentów z bezobjawowo zatrzymanymi trzecimi zębami trzonowymi żuchwy. Byli oni leczeni na Oddziale Stomatologii Chirurgicznej i Chirurgii Szczękowo- -Twarzowej w Lwowskim Uniwersytecie Medycznym im. Daniela Halickiego w latach Wyniki. W celu uzasadnienia usunięcia bezobjawowych zatrzymanych trzecich zębów trzonowych żuchwy badano znane parametry kliniczne i radiologiczne charakteryzujące zatrzymane trzecie zęby trzonowe w żuchwie, nie wykazujace wskazań i przeciwwskazań do atypowego usunięcia. Nie było żadnych znaczących powikłań śród- i pooperacyjnych w pierwszej podgrupie (41 przypadków klinicznych u pacjentów w wieku lat); nieznaczne komplikacje w drugiej podgrupie (10 przypadków klinicznych u pacjentów w wieku lat). U 68-letniego pacjenta wszystkie powikłania były związane ze znaczną atrofią kości żuchwy w obszarze operacyjnym. 5 z 7 przypadków klinicznych w grupie kontrolnej wymagało interwencji chirurgicznej z powodu pojawienia się wskazań w ciągu najbliższych 5 lat obserwacji. Trzecie zęby trzonowe żuchwy z grupy kontrolnej w ciągu pięciu lat nie wykazywały patologicznych zmian, które nakazywałyby ich usunięcie. Wnioski. Zaproponowane kryteria dają wskazania do odpowiedniego leczenia bezobjawowych i niewykazujących zmian patologicznych zatrzymanych trzecich zębów trzonowych w żuchwie. Niski odsetek powikłań śród- i pooperacyjnych nie daje żadnego powodu do pozostawienia zęba mądrości z łagodną chorobą objawową lub bezobjawowego zęba mądrości ze złym rokowaniem miejscowym, ponieważ wczesne interwencje chirurgiczne wywołują mniejszą liczbę powikłań, przy czym okres operacyjny i pooperacyjny jest krótszy (Dent. Med. Probl. 2014, 51, 1, 35 42). Słowa kluczowe: bezobjawowy ząb trzonowy, zatrzymanie, atypowe usunięcia. Tooth impaction is one of the most common pathologies in our everyday practice. Furthermore, it presents the greatest surgical challenge and provokes the biggest controversy when indications for removal are considered. During the recent years there has been a debate over the advisability of removing symptom-free wisdom teeth or leaving them in place [1 3]. One of the main reasons for removing a symptom-free wisdom tooth is the high incidence of their late complications, low incidence of their eruption, especially after the age of 25, and 2 times greater risk of complications after the age of 24 [4 7]. According to M. Miloro et al., an impacted tooth can cause mild to severe complications if it remains unerupted. Not every impacted tooth causes problems of clinical value but each one has a potential for it . For example, partial retention of a wisdom tooth is very common but lack of competence and sometimes carelessness of surgeons may lead to severe complications . Opponents of prophylactic removal of wisdom teeth consider that most of third molars, impacted or not, remain without changes, but the risk of iatrogenic complications because of surgical manipulations is higher than the risk to leave asymptomatic tooth that does not [resent considerable pathological changes [9, 10]. The decision to remove impacted teeth should be based on the thorough evaluation of potential benefits and risks. In the case when pathology exists, the decision to remove is not complicated and vice versa; such situations exist when the removal of an asymptomatic impacted tooth is contraindicated, while surgical complications may exceed the possible benefits . The aim of our investigation was to systematize a scheme of objective preoperative clinical and roentgenological assessment of mandibular impacted symptom-free wisdom teeth to create a rationale for their prophylactic removal. Material and Methods Material and methods of the investigation were 84 clinical cases of patients with impaction of asymptomatic and mandibular third molars that did not present any considerable pathological changes; these patients have been treated in the Department of Surgical Dentistry and Maxillofacial Surgery of Lviv Danylo Halytsky National Medical University during clinical cases of impacted mandibular third molars that were removed according to the results of the proposed tables compose the main group with 3 subgroups (first subgroup 41 cases of patients years old, second subgroup 10 cases of year old patients, and third subgroup 1 case of 68 year old patient). Control group # 1 consists of 7 clinical cases of patients that according to the proposed tables needed their mandibular third molars removed but refused to remove them. Control group # 2 consists of 25 clinical cases of patients that according to the proposed tables at the time of diagnostic did not need their mandibular third molars removed. Results In order to justify the removal of a symptomfree mandibular impacted third molar, a specialist
3 Management of Mandibular Impacted Third Molars 37 needs to compare all possible pathological changes and complications in the area of the tooth in question in case of different treatment tactics. We processed the known clinical, roentgenological parameters, which characterize asymptomatic mandibular impacted third molars that do not present any considerable pathologic changes and do not belong to the list of indications and contraindications to atypical removal, but in complex estimation can play a considerable role while planning a tactic concerning the aforementioned teeth. Processed characteristics were classified into a table, which also includes the age and other parameters. The table is classified according to a treatment tactic of an impacted mandibular third molar (Table 1). Table 1.

4 38 Y. Vares, S. Kyyak Each item may have positive or negative valuation (conduct surgery or not, respectively) in accordance to a clinical case, which has been noted in an appropriate column. In the scheme of general criteria we included: operator s experience, age, weight, sex of a patient, frequency of acute respiratory diseases, readiness of a patient to systematic observation, bad habits, and severity of gag reflex. The scheme of clinical criteria contains: an oral hygiene state, presence of an erupted opposite upper third molar, presence (in anamnesis) of perecoronaritis, presence of plaque distally on a third molar, results of periodontal probe distally to a third molar. In roentgenological characteristics we included: a degree of third molar follicle enlargement, root morphology, proximity to the mandibular canal, angulation, as well as such important characteristic as depth according to the occlusal line, position in relation to the anterior edge of mandibular ramus, evaluation of contact with the second molar, presence of bone and risk of its loss distally along the second molar. The third molar removal was conducted using the surgical bur technique. In accordance with the severity of impaction, a proper incision and tooth sectioning were made following the strict conventional scheme and with a minimization of the distal bone removal and the operative time. Clinical Case no. 1 Patient K., 28 years old, entered our department after a trauma of the maxillofacial area. A panoramic radiography was made (Fig. 1). An asymptomatic impacted mandibular third molar that did not present any considerable changes was revealed. The data was entered into the table (Table 2) and the result was negative, thus, the operative treatment was not conducted. Clinical Case no. 2 Patient, 30 years old, entered our department.

7 Management of Mandibular Impacted Third Molars 41 Patients from control group # 1 were subjected to annual long-term follow-ups. Five of 7 clinical cases from control group needed surgical intervention because of the appearance of indications during the next 5 years of follow-ups. Patients from control group # 2 were also subjected to annual long-term follow-ups and still for the last 5 years there were no pathological changes in those teeth that may warrant their removal. Discussion On the basis of our own observations and analysis of specialized literature, we revealed that 17 32% of the population has third molars, and 73.5% of them are mandibular ones. Almost one third of impacted third molars are those with perspective of eruption. Symptomatic impacted mandibular third molars make 20%, 8 10% of which are with pericoronitis, and the rest (80%) are asymptomatic, respectively. Postoperative complications occur in 30 40% of cases where pain is not considered, but trism and swelling make approximately 9 and 11% respectively. More risk of pathological changes is caused by partial retention, while the postoperative period in this case runs with minor complications. Taking into consideration our research, we can agree with some studies [4 7] that the risk of complications resulting from the removal of a third molar grows approximately twice after the age of 24. Hence, the best time for their removal is the age of . We consider that if impacted mandibular third molar has more characteristics from the positive valuation column from the table it belongs to risk group. That means the surgeon in the future should expect the development of any pathology that will warrant the removal of aforementioned impacted mandibular tooth. Moreover, if these patients do not undergo at least an annual follow-up, the pathology may develop in an uncontrolled manner and a number of impacted mandibular third molar pathologic changes may be clinically silent. Undesired progression of pathological changes, if not mentioned, increases with time; other risk factors like age etc. can lead to more complicated procedures of removal. Hence, surgeons should consider all factors, since the tooth that has mostly positive valuation in our table will, in most cases, develop a pathology finally requiring the removal of the tooth. Considering the above-mentioned, all the chosen criteria facilitate the formation of indications for a proper treatment tactic regarding asymptomatic impacted mandibular third molars that do not present any considerable pathological changes. Knowledge of clinical, roentgenological assessment of a mandibular wisdom tooth and further step-by-step surgical technique of its removal provide a great possibility of successful intra- and post-operative management of patients with vertical, mesioangular, horizontal and distoangular impaction without any severe complications. The low-to-no percentage of intra- and post-operative complications does not give any reason to leave a wisdom tooth with minor clinical manifestations or an asymptomatic wisdom tooth with bad prognosis in place, since early surgical procedures generate less number of complications, having shorter operative time and postoperative period.
